Step-by-step explanation:

Solve the equations by getting x all by itself on one side. Then, square root to get rid of the exponent.

Any problem where you square root a negative will give you an i in the answer. This is because sqrt(-1) is i. Because i^2 = -1

Also, when you are simplifying square roots for your final answer, look for a perfect square number inside of the radical. Like Sqrt45 can be broken down to

Sqrt9•sqrt5

And because 9 is a perfect square, sqrt9 simplifies to just 3. See image.

A X = 5b. X = 5iC. X = 35d. X = 33e. X = 3i3f. X= 3i51. X^2+45=02. X^2=-253. X^2-25=04. X^2-45=05. X^2=276.

Ashley got a prepaid debit card with $30 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 13 cents per yard. If after that purchase there was $25.06 left on the card, how many yards of ribbon did Ashley buy?

Answers

Answer:

38 yards

Step-by-step explanation:

First, subtract to find out how much money was spent.

30 - 25.06

= 4.94

Then divide to find out how many groups of $0.13 are in $4.94.

4.94 ÷ .13

= 38

Ashley bought 38 yards of ribbon.

38 × .13 = 4.94

4.94 + 25.06 = 30

This answer does not consider tax at all. Because it wasn't mentioned in the question and it complicates the problem. So probably don't worry about tax. Unless your teacher /book/program said to consider it. I can edit the answer.

Also, if they said to write an equation:

Let x = yards of ribbon

30 - .13x = 25.06

subtract 30

-.13x = -4.94

divide by -.13

x = 38

Solve the system of equations :-)
Thank you

Answers

We have the equations:
4x - y + 3z = 12 ...(1)
2x + 9z = -5 ...(2)
x + 4y + 6z = -32 ...(3)

From equation (2), we can express x in terms of z:
2x = -9z - 5
x = (-9z - 5) / 2 ...(4)

Substitute equation (4) into equations (1) and (3):

From equation (1):
4((-9z - 5) / 2) - y + 3z = 12
-18z - 10 - y + 3z = 12
-15z - y = 22 ...(5)

From equation (3):
((-9z - 5) / 2) + 4y + 6z = -32
-9z - 5 + 8y + 12z = -64
3z + 8y = -59 ...(6)

Now we have a system of two equations in terms of y and z.

To solve the system, let's multiply equation (5) by 3 and equation (6) by 15 to eliminate z:

-45z - 3y = 66 ...(7)
45z + 120y = -885 ...(8)

Add equations (7) and (8):
-3y + 120y = 66 - 885
117y = -819
y = -7

Substitute y = -7 into equation (7):
-45z - 3(-7) = 66
-45z + 21 = 66
-45z = 45
z = -1

Substitute y = -7 and z = -1 into equation (4):
x = (-9(-1) - 5) / 2
x = (9 - 5) / 2
x = 2

Therefore, the solution to the system of equations is:
x = 2
y = -7
z = -1

Explain what is meant by a positive relationship between two variables and a negative relationship between two variables. Give an example of a situation in which you would expect to find a positive relationship and when you would expect to find a negative relationship.

Answers

Answer: A positive relationship between two variables means that as the value of one variable increases, the value of the other variable also increases. In other words, there is a direct association or correlation between the two variables. Graphically, a positive relationship is represented by an upward-sloping line or curve.

For example, let's consider the relationship between studying time and exam scores. In general, if a student spends more time studying for an exam, their exam score is likely to increase. This implies a positive relationship between studying time and exam scores.

On the other hand, a negative relationship between two variables means that as the value of one variable increases, the value of the other variable decreases. In this case, there is an inverse association or correlation between the two variables. Graphically, a negative relationship is represented by a downward-sloping line or curve.

For instance, let's consider the relationship between hours of sleep and levels of fatigue. As the number of hours of sleep decreases, the level of fatigue tends to increase. This indicates a negative relationship between hours of sleep and levels of fatigue.

It's important to note that these examples describe typical scenarios, but individual variations and other factors can also influence the relationships between variables.

Answers

The expected value for a person who buys a ticket is $0.35.

We have,

Number of tickets sold = 100

Price of each ticket = $1

Prize value (1st prize) = $25

Prize value (2nd prize) = $10

Let's calculate the expected value step by step:

Calculate the probability of winning each prize:

Since there is only one 1st prize and one 2nd prize, the probability of winning each prize is:

Probability of winning the 1st prize = 1/100

Probability of winning the 2nd prize = 1/100

Calculate the expected value:

Expected value = (Probability of winning 1st prize x Value of 1st prize) + (Probability of winning 2nd prize x Value of 2nd prize)

= (1/100 x $25) + (1/100 x $10)

= $0.25 + $0.10

Part B. Calculate and compare the variability in each distribution.
Part C. Does the data support juniors or seniors spending more time on homework?

Answers

Mean (Juniors) = Sum / number of data points = 1085 / 12 ≈ 90.42

Median (Juniors) = (95 + 95) / 2 = 95

Mean (Seniors) = Sum / number of data points = 1095 / 12 ≈ 91.25

Median (Seniors) = (80 + 80) / 2 = 80

How to solve for the median of center

Juniors: 125, 90, 95, 80, 100, 100, 120, 85, 95, 120, 95, 85

First, sort the data: 80, 85, 85, 90, 95, 95, 95, 100, 100, 120, 120, 125

Sum = 1085

Mean (Juniors) = Sum / number of data points = 1085 / 12 ≈ 90.42

Median (Juniors) = (95 + 95) / 2 = 95

Seniors: 135, 70, 65, 100, 35, 175, 80, 80, 90, 65, 120, 60

First, sort the data: 35, 65, 65, 70, 80, 80, 90, 100, 120, 120, 135, 175

Juniors:

Range = max - min = 125 - 80 = 45

Seniors:

8. For positive real numbers a, b, and c, the expressions albici and Vabac are equivalent. What are the values
of p, q, and r?

Answers

Answer:

Step-by-step explanation:

To find the values of p, q, and r in the expression albici = Vabac, we need to equate the corresponding parts on both sides.

From the given equation, we have:

p * (a * b) * (c * i) = q * (a * b * a * c)

Comparing the exponents of a, b, and c on both sides, we get:

p = q * a^2

1 = q * c

To determine the value of r, we can use the fact that albici and Vabac are equivalent. The radical symbol (√) represents taking the square root.

√(a * b * c * i) = √(a * b * a * c)

This implies that:

√(a * b * c * i) = √(a^2 * b * c)

Comparing the exponents of a, b, and c on both sides, we get:

1/2 = 2 * p * q * r

Combining all the equations, we have:

p = q * a^2

1 = q * c

1/2 = 2 * p * q * r

To find the specific values of p, q, and r, we need additional information or equations involving a, b, and c. Without more context or equations, it is not possible to determine the exact values of p, q, and r.

Answers

78,624,000 different license plates are possible if letters and digits cannot be repeated.

For the letters:

There are 26 letters in the English alphabet, and we need to choose three of them without repetition.

This can be calculated as a permutation of 26 letters taken 3 at a time:

P(26, 3) = 26! / (26 - 3)!

= 26! / 23!

= 26 x 25 x 24

= 15,600

For the digits:

There are 10 digits (0-9), and we need to choose four of them without repetition.

This can be calculated as a permutation of 10 digits taken 4 at a time:

P(10, 4) = 10! / (10 - 4)! = 10! / 6!

= 10 x 9 x 8 x 7

= 5,040

To find the total number of different license plates possible, we multiply the number of possibilities for the letters by the number of possibilities for the digits:

In trigonometry,

The sine function (sin) represents the ratio of the length of the side opposite an angle in a right triangle to the length of the hypotenuse.

The cosecant function (csc) is the reciprocal of the sine function, meaning it is equal to 1 divided by the sine of an angle.

In this case,

We are given that csc θ (the cosecant of θ) is equal to 13/9.

To find the value of sin θ (the sine of θ), we can take the reciprocal of csc θ. So,

How to obtain the period of the function?

A periodic function is a function that has the behavior repeating in intervals over the domain.

Then the period of the function is defined as the difference between two points in which the function has the same behavior.

The function in this problem has the behavior repeating at these following points:

x = 0, x = 4, x = 8, ...

Hence the period is given as follows:

4 - 0 = 8 - 4 = 4.

The graph of the proportional relationship is a linear graph, with slope of 4.6 and intercept of zero.

What is a proportional relationship?

A proportional relationship is a relationship in which a constant ratio between the output variable and the input variable is present.

The equation that defines the proportional relationship is a linear function with slope k and intercept zero given as follows:

y = kx.

The slope k is the constant of proportionality, representing the increase or decrease in the output variable y when the constant variable x is increased by one.

Hence the graph is a linear function with slope of k and intercept of zero.

The cost of 4 pints is of $18.4, and the cost of 10 pints is of $46, hence the slope of the relation is given as follows:

k = 46/10 = 18.4/4 = 4.6.

The measures of dispersions are;

Rangeinterquartile range standard deviation

From the information given, if 4 is added to all the measures, we get;

Mean = 15 + 4 = 19

Median = 16 + 4 = 20

Mode = 18 + 4 = 22

Standard deviation = 3.2 + 4 = 7.2

Range = 20 + 4 = 24

If the values are multiplied by 5

Mean = 15(5) = 75

Median = 16(5) =  80

Mode = 18(5) = 90

Standard deviation = 3.2(5) = 16

Range = 20(5) = 100

O is the center of the decagon below. Find its area. Round to the nearest tenth if necessary.

Answers

Answer:

752.4

Step-by-step explanation:

Here we are provided with a decagon which has 10 sides.

The total interior angle is 360°.

So each will have 360/10 = 36 degrees

Half of that is 18 degrees inside the triangle.

Refer to the attachment below.

opposite = 16sin(18)

adjacent = 16cos(18)

Find the area of this triangle:

= 1/2 × 16sin(18) × 16cos(18)

= 37.61825

There are 20 triangles just like this so the total area is (37.61825 × 20) = 752.365 ≈ 752.4 unit2
