Answer:

the pressure of the gas at a volume of 16 L would be 28 kPa.

Step-by-step explanation:

Using Boyle's Law:

P1V1 = P2V2

Where:

P1 = 112 kPa (initial pressure)

V1 = 4 L (initial volume)

V2 = 16 L (final volume)

Solving for P2:

P2 = (P1 x V1) / V2

P2 = (112 kPa x 4 L) / 16 L

P2 = 28 kPa

Therefore, the pressure of the gas at a volume of 16 L would be 28 kPa.

Since the 95% confidence interval includes zero, we cannot conclude that the population means are different without conducting the test in part a.

a. Significance test:

Null hypothesis (H0): The population means are equal for females and males (μ1 = μ2).

Alternative hypothesis (H1): The population means are not equal for females and males (μ1 ≠ μ2).

Significance level (α): 0.05

We will use a two-sample t-test for independent samples to compare the means:

Calculate the pooled variance (Sp^2):

Sp^2 ≈ 5.27

Calculate the standard error (SE):

SE ≈ 0.11

Calculate the t-statistic:

t ≈ 1.18

Calculate the degrees of freedom (df):

df = N1 + N2 - 2

df = 1117 + 870 - 2

df = 1985

Comparing the t-statistic and the critical t-value for a two-tailed test with α = 0.05:

t_critical ≈ ±1.96 (from t-distribution table)

Since -1.96 < 1.18 < 1.96, we fail to reject the null hypothesis.

Conclusion: There is insufficient evidence to conclude that the population means differ for females and males at a 0.05 significance level.

b. 95% confidence interval:

Calculate the margin of error (ME):

ME = t_critical * SE

ME = 1.96 * 0.11

ME ≈ 0.22

Calculate the difference in means (M_diff):

M_diff = M1 - M2

M_diff = 2.99 - 2.86

M_diff = 0.13

Determine the 95% CI for the difference in means:

CI = (0.13 - 0.22, 0.13 + 0.22)

CI ≈ (-0.09, 0.35)

Since the 95% confidence interval includes zero, we cannot conclude that the population means are different without conducting the test in part a.

So Wanda will make more money from the second deal than the first deal if she sells more than 20,000 books.

In mathematics, an inequality is a statement that two values or expressions are not equal. It describes a relationship that is either greater than, less than, or not equal to another value or expression. Inequalities are often represented using symbols such as > (greater than), < (less than), ≥ (greater than or equal to), and ≤ (less than or equal to).

Here,

To determine the range of sales for which Wanda would make more from the second deal than the first deal, we need to set up an inequality that compares the total earnings for each deal. Let's let x be the number of books sold.

For the first deal, Wanda will earn:

Total earnings = $70,000 + $2x

For the second deal, Wanda will earn:

Total earnings = $40,000 + $3.50x

We want to find the range of x values for which the second deal earns more than the first deal. Mathematically, we can express this as:

$40,000 + $3.50x > $70,000 + $2x

Subtracting $2x from both sides gives:

$40,000 + $1.50x > $70,000

Subtracting $40,000 from both sides gives:

$1.50x > $30,000

Dividing both sides by $1.50 gives:

Step-by-step explanation:

The volume of a cylinder can be calculated using the formula V = πr^2h, where V is the volume, r is the radius, and h is the height.

The current volume of the cylinder is:

V = π(12cm)^2(15cm)

V = π(144cm^2)(15cm)

V = 2160π cm^3

If the dimensions of the cylinder are tripled, then the new cylinder will have a radius of 3(12cm) = 36cm and a height of 3(15cm) = 45cm.

The new volume of the cylinder is:

V = π(36cm)^2(45cm)

V = π(1296cm^2)(45cm)

V = 58320π cm^3

Simplifying the expression, we get:

V ≈ 183,124.8 cm^3

Therefore, the volume of the new cylinder, when the dimensions are tripled, is approximately 183,124.8 cm^3.

Answer: No, it is not likely that 60% of Skyline College students say math is their favorite subject based on the given confidence interval of (0.6358, 0.7532).

The confidence interval tells us that we are 95% confident that the true proportion of Skyline College students who say math is their favorite subject lies between 0.6358 and 0.7532. This means that if we were to take many random samples from the population of Skyline College students and construct 95% confidence intervals for the proportion of students who say math is their favorite subject, 95% of those intervals would contain the true population proportion.

Since 0.60 is not within the interval (0.6358, 0.7532), it is unlikely that the true proportion of Skyline College students who say math is their favorite subject is 60%. However, we cannot make any definitive statements about the population proportion based on this one confidence interval alone.

Parallel cross sections of a sphere look like circles with the same radius as the sphere, while perpendicular cross sections look like points. Cross sections taken at other angles will be ellipses.

A sphere is a three-dimensional geometric shape that is perfectly round in shape, like a ball. It is defined as the set of all points in three-dimensional space that are at a constant distance (the radius) from a given point called the center.

If we take a cross section of a sphere, the resulting shape will depend on the angle at which the section is taken relative to the center of the sphere.

If we take a plane that is parallel to the base of the sphere, the cross section will be a circle with the same radius as the sphere. This is because the intersection of the plane with the sphere will be a circle, and since the plane is parallel to the base of the sphere, the circle will have the same radius as the sphere.

On the other hand, if we take a plane that is perpendicular to the base of the sphere, the cross section will be a point. This is because the plane will intersect the sphere at only one point, which is the point at which the plane is perpendicular to the sphere.

If we take a plane that is neither parallel nor perpendicular to the base of the sphere, the resulting cross section will be an ellipse. The size and shape of the ellipse will depend on the angle at which the plane intersects the sphere.

Recall the point-slope form of a linear equation:

[tex]y-y_{1}=m(x-x_{1} )[/tex]

Where y1 and x1 are points from the ordered pair (x1, y1),

and m represents the slope of the line.

We are given that the point (-5, 7) belongs to the graph. Here, the x-coordinate is -5, and the y-coordinate is 7.

Let's plug in these values, were x1=-5, and y1=7:

[tex]y-y_{1}=m(x-x_{1} )=\\y-7=m(x-(-5))=\\y-7=m(x+5)[/tex]

We are also given that the slope is -4/3.

In other words, m=-4/3. Let's plug this value in:

[tex]y-7=m(x+5)=\\y-7=-\frac{4}{3}(x+5)[/tex]

Thus, the answer is C.

Answer:

C

Step-by-step explanation:

The point-slope form of the equation of a line passing through the point (x1, y1)with a slope of m is given by:

y - y1 = m(x - x1)

To find the equation of the line passing through the point (-5, 7)with a slope of -4/3, we substitute m = -4/3, x1 = -5, and y1 = 7 into the point-slope form equation:

y - 7 = (-4/3)(x - (-5))

Simplifying this equation, we get the final result in slope-intercept form:

y = (-4/3)x + (17/3)

Therefore, the equation of the line in a point-slope form that passes through (-5,7) and has a slope of -4/3 is y + 7 = -4/3 (x + 5)

Answer: 350

Step-by-step explanation:

First, 32% divided by 100 becomes a decimal.

     32% / 100 = 0.32

Next, let x be equal to a number.

Then, "of" indicates multiplication and "is" indicates equals.

     0.32x = 112

Lastly, we will divide both sides of the equation by 0.32.

     x = 350

This problem can be represented by turning 32% into a decimal and rewriting it like this: .32x = 112, where x is the unknown number. Dividing both sides of the equation by .32 gives you x = 350, so 32% of 350 is 112

The probability of drawing a matching pair of socks is 1/5 or 0.2.

The basic principle of probability, states that the probability of an event happening is the number of ways the event can occur divided by the total number of possible outcomes.

In this problem, we first calculated the number of ways to draw a matching pair of socks for each of the three possible colors.

We then added these probabilities together to get the total probability of drawing a matching pair of socks.

Here we have

A box contains two white socks, two blue socks, and two red socks.

To find the probability of drawing a matching pair of socks, consider the different cases of matching pairs of socks that can be drawn.

Case 1: Matching white socks

The probability of drawing one white sock = 2/6

After drawing one white sock,

Remains 5 socks and of which 1 is white

The probability of drawing 2nd white sock =  1/5  

Hence, probability of selecting 2 white socks = (2/6) × (1/5) = 1/15

Similarly, we can calculate probabilities for Red and Blue socks

Case 2: Matching blue socks

The probability of drawing two blue socks is (2/6) × (1/5) = 1/15  

Case 3: Matching red socks

The probability of drawing two red socks is (2/6) × (1/5) = 1/15.

Therefore, the total probability of drawing a matching pair of socks is the sum of the probabilities of each of these cases:

P(matching pair) = P(white) + P(blue) + P(red)

= 1/15 + 1/15 + 1/15 = 3/15 = 1/5

Therefore,

The probability of drawing a matching pair of socks is 1/5 or 0.2.

A measure of relative fit for a simple regression line is called the r² or coefficient of determination.

A regression line, or line of best fit, is a straight line used to model the relationship between two variables in a data set. It is drawn through the data points to minimize the distance between the line and the points, representing the best fit. The line's equation is y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope, and b is the y-intercept. The slope represents the rate of change of y with respect to x, and the y-intercept represents the value of y when x is equal to 0. The line is often used to predict the dependent variable based on the independent variable, and the accuracy of the predictions depends on how well the line fits the data.

The coefficient of determination, also known as r², is a statistical measure used to determine the relative fit of a simple regression line. This measure represents the proportion of variance in the dependent variable that can be predicted by the independent variable. The calculation involves squaring the correlation coefficient (r) between the two variables. The resulting value of r² ranges from 0 to 1, where 0 indicates that the independent variable has no explanatory power over the dependent variable, while 1 implies that the independent variable explains all the variability in the dependent variable.

d) z₀ = 1.85

The P-value is calculated for as follows P ( z > z₀) = 1 - P( z≤ z₀)

= 1 - P( z≤ 1.85)

Now, using the normal distribution table , the value of P( z≤ 1.85 ) is equals to 0.032157. So, P( z> 1.85) = 1 - 0.032157

=0.967843

e) z₀ = -0. 15

The P-value is calculated for as follows P ( z > -z₀) = P( z ≤ z₀)

The roof area is 468.75 square feet.

To find the roof area, we need to follow these steps:
Determine the rise (vertical distance) using the slope of 9 inches per foot:

Since the run is 10 feet, the rise is 9 inches/foot × 10 feet = 90 inches.
Convert the rise to feet: 90 inches ÷ 12 inches/foot = 7.5 feet.
Calculate the length of the rafter using the Pythagorean theorem:

Rafter length = √(run² + rise²) = √(10² + 7.5²) = √(100 + 56.25) = √156.25 = 12.5 feet.
Determine the total length of the gable roof:

Since the rake slope is 1.25, we have Total length = Rafter length × Rake slope = 12.5 feet × 1.25 = 15.625 feet.

Answer: 6(x - (23/2))² = 14x + 1044

Step-by-step explanation:

First, we need to move all the terms to one side of the equation:

6x² - 46x - 312 - 14x = 0

Next, we need to factor out the coefficient of the x² term:

6(x² - (46/6)x) - 312 - 14x = 0

Simplifying:

6(x² - 23x) - 312 - 14x = 0

To complete the square, we need to add and subtract the square of half the coefficient of the x-term inside the parentheses:

6[(x - (23/2))² - (23/2)²] - 312 - 14x = 0

Simplifying:

6(x - (23/2))² - 6(23/2)² - 312 - 14x = 0

Expanding the square term:

6(x - (23/2))² - 1044 - 14x = 0

Finally, adding 1044 to both sides and simplifying:

6(x - (23/2))² = 14x + 1044

The intermediate step after completing the square is:

6(x - (23/2))² = 14x + 1044

The area of the floor of the igloo is 842.9 m²

We know that the formula for the volume of hemisphere is given by,

V = (2/3) × π × r³

where r is the radius of the hemisphere

Here, a hemisphere igloo has a volume of about 9,202.8 m³

Using above formula of the volume of hemisphere,

V = (2/3) × π × r³

9202.8 = (2/3) × π × r³

r³ = 9202.8 × (3/2π)

r³ = 4394.01

r = 16.38 m

We know that the area of the floor of the igloo is equivalent to the area of circle, as the base of hemisphere is a circle.

So, the area of the floor of the igloo would be,

only the equation y=1/x shows an indirect proportional relationship, while the other three equations show either a direct proportional or a linear relationship.

How to solve the question?

The mathematical term "indirectly proportional" refers to a relationship in which two variables are related in such a way that when one increases, the other decreases, and vice versa. In other words, the two variables vary in opposite directions.

Out of the four equations given, only one shows an indirect proportional relationship. This equation is:

y=1/x

In this equation, y and x are indirectly proportional. As x increases, the value of 1/x decreases, and therefore, the value of y decreases as well. Similarly, as x decreases, the value of 1/x increases, and the value of y increases as well. This relationship is commonly known as an inverse relationship, where the two variables vary in opposite directions.

On the other hand, the other three equations do not show an indirect proportional relationship. The equation y=5x shows a direct proportional relationship, where y increases as x increases and vice versa. The equation y=-2x+1 is a linear equation with a negative slope, where y decreases as x increases, and y increases as x decreases. Lastly, the equation y=3x+5 is also a linear equation with a positive slope, where y increases as x increases, and y decreases as x decreases.

In summary, only the equation y=1/x shows an indirect proportional relationship, while the other three equations show either a direct proportional or a linear relationship.
