The probability that a random sample of 150 bowlers will have an average score greater than 165 is 0

Probability is a branch of mathematics that deals with the study of random events or outcomes. It is used to measure the likelihood or chance of an event occurring, ranging from impossible (0 probability) to certain (1 probability).

The basic concept of probability involves determining the ratio of the number of favorable outcomes to the total number of possible outcomes. This ratio is expressed as a fraction, decimal, or percentage.

For example, if you toss a fair coin, there are two possible outcomes: heads or tails. The probability of getting heads is 1/2 or 0.5 or 50%, and the probability of getting tails is also 1/2 or 0.5 or 50%.

To give the probability that a random sample of 150 bowlers will have an average score greater than 165

P( [tex]\bar X[/tex]> 165) = P(z > (165 - 157)/(12/√(150)))

= P(z > 8.16)

= 0 [since from z table]

To find the scale factor of the dilation, we can compare the corresponding dimensions of the original and the enlarged card.

The original card has a length of 3 1/2 inches and is being enlarged to a length of 5 1/4 inches. So the scale factor for the length is:

5 1/4 inches / 3 1/2 inches = 3/2

Similarly, the original card has a width of 2 inches and is being enlarged to a width of 3 inches. So the scale factor for the width is:

3 inches / 2 inches = 3/2

Therefore, the scale factor of the dilation is 3/2 or 1.5.

Therefore , the solution of the given problem of ordered pair comes out to be system of equations is the ordered pair (-4, 1).

Two independent variables that are grouped in a fashion that suggests a particular order are known as "ordered pairs." The 1 and 2 parts each indicate one of an order pair's y-coordinates. The ordered pair is shown in close parenthesis in the example that follows.

Here,

We can solve this system of equations by substitution or elimination.

Here's how to do it using the substitution method:

From the first equation, we know that y = x + 5. We can substitute this expression for y in the second equation to get:

$x - 5y = -9

$x - 5(x + 5) = -9

$x - 5x - 25 = -9

Simplifying the equation, we get:

$-4x = 16$

$x = -4$

Now that we know the value of x, we can substitute it back into the first equation to find y:

y = x + 5 = -4 + 5 = 1$

Therefore, the solution to the system of equations is the ordered pair (-4, 1).

what is percentage ?

Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the % symbol. For example, 50% means 50 out of 100, or 0.5 as a decimal.

According to question:
A. Joey's answer of 180 is not correct. If 300 students are currently mastering their math lessons and this represents 60% of the total number of students in Math 6, we can use the following equation to find the total number of students in Math 6:

60% of the total number of students = 300

0.6 × Total number of students = 300

Total number of students = 300 ÷ 0.6

Total number of students = 500

Therefore, there are 500 students in Math 6, not 180.

B. It is possible that Joey used a method called "guess and check" to arrive at his answer of 180. This method involves guessing a number, plugging it into an equation or problem, and checking to see if it is the correct answer. While this method can be useful in some cases, it is not a reliable method for solving this problem since there are an infinite number of numbers to guess from and the probability of guessing the correct answer is low.

C. To solve this problem correctly, we can use a percent equation. We know that 60% of the students in Math 6 are mastering their math lessons, so we can write:

0.60 × Total number of students = 300

To solve for the total number of students, we can divide both sides of the equation by 0.60:

Total number of students = 300 ÷ 0.60

Total number of students = 500

Therefore, the final answer is that there are 500 students in Math 6.

Step-by-step explanation:

To find the value of (f-g)(2), we first need to compute the function (f-g), which is defined as the difference between f(x) and g(x), and then evaluate it at x=2.

So, (f-g)(x) = f(x) - g(x)

Substituting the given functions, we get:

(f-g)(x) = (3x^2 + 1) - (1-x)

(f-g)(x) = 3x^2 + x

Now, to find (f-g)(2), we substitute x=2 into the expression we just obtained:

(f-g)(2) = 3(2)^2 + 2

(f-g)(2) = 3(4) + 2

(f-g)(2) = 12 + 2

(f-g)(2) = 14

Therefore, the value of (f-g)(2) is [14.]

Answer:

what basic business principle does the author of your reading material state that automakers igno red in recent years leading to the need for an industry bailout

Answer:

Step-by-step explanation:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line is a measure of how steep the line is, and it is defined as the change in y divided by the change in x between any two points on the line. In other words, if we choose two points (x1, y1) and (x2, y2) on the line, then the slope of the line is:

m = (y2 - y1) / (x2 - x1)

The y-intercept of a line is the point where the line crosses the y-axis. In other words, it is the value of y when x = 0. To find the y-intercept of a line given in slope-intercept form, we simply look at the constant term (the term with no x) in the equation.

In the given equation, y = -6x - 7, we can see that the coefficient of x is -6, which means that the slope of the line is -6. This tells us that as we move along the line from left to right, the y-value will decrease by 6 units for every 1 unit that the x-value increases. In other words, the line is sloping downwards from left to right.

To find the y-intercept of the line, we look at the constant term, which is -7. This tells us that when x = 0, y is equal to -7. So the y-intercept is the point (0, -7), which means that the line crosses the y-axis at the point (0, -7).

To summarize, the slope of the line y = -6x - 7 is -6, which means that the line is sloping downwards from left to right. The y-intercept of the line is (0, -7), which means that the line crosses the y-axis at the point (0, -7).

The event with the highest probability is "reaching into a bag full of 50 strawberry chews and 10 cherry chews without looking and pulling out a strawberry chew", with a probability of 5/6 or approximately 0.83. Option D

To determine which event is most likely to occur, we need to compare the probabilities of each event happening.

Rolling a multiple of 4 on an eight-sided die:

There are 8 possible outcomes when rolling an eight-sided die, and 2 of them are multiples of 4 (4 and 8). So, the probability of rolling a multiple of 4 is 2/8, or 1/4.

Spinning a spinner and landing on pink:

There are 4 possible outcomes when spinning the spinner, and only one of them is pink. So, the probability of landing on pink is 1/4.

Winning a raffle that sold a total of 100 tickets, if you buy 53 tickets:

The total number of possible outcomes is the total number of tickets sold, which is 100. The number of favorable outcomes is the number of tickets the person bought, which is 53. So, the probability of winning the raffle is 53/100.

Reaching into a bag full of 50 strawberry chews and 10 cherry chews without looking and pulling out a strawberry chew:

The total number of possible outcomes is the total number of candies in the bag, which is 50 + 10 = 60.

The number of favorable outcomes is the number of strawberry chews in the bag, which is 50. So, the probability of pulling out a strawberry chew is 50/60, which simplifies to 5/6.

Comparing the probabilities, we can see that the event with the highest probability is "reaching into a bag full of 50 strawberry chews and 10 cherry chews without looking and pulling out a strawberry chew", with a probability of 5/6 or approximately 0.83. Therefore, this event is the most likely to occur.

Using Pythagoras' Theorem, we found the length of Road C and the respective time taken to travel along each road.

What is meant by Pythagoras' theorem?

The Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse. In essence, Pythagoras' theorem is used to determine a triangle's angle and length of an unknown side. This theorem allows us to obtain the hypotenuse, perpendicular, and base formulas.

The given figure is a right triangle.

The length of road A = 16.01 km

The length of road B = 10 km

a) The length of road C can be found using Pythagoras' theorem.

From figure,

A² = B² + C²

16.01 ² = 10² + C²

C² = 156.32

C = 12.5 km

b) Speed of bike = 19.5 km/h

   Length of road C = 12.5 km

Time = Length/speed = 12.5/19.5 = 0.64 hours

 Length of road B =10 km

Time = Length/speed = 10/19.5 = 0.51 hours

c) Length of road A = 16.01

Time taken = Length/speed = 16.01/19.5 = 0.82 hours.

Therefore using Pythagoras' Theorem, we found the length of Road C and the respective time taken to travel along each road.

The sample space lists all possible outcomes of rolling a number cube twice, where W represents a roll with a value of 6 or higher, and L represents a roll with a value of 5 or lower.

What is probability ?

Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.

The answer to Question 3 is List 2, which gives the sample space for pulling 2 marbles from the bag with replacement.

The answer to Question 4 is two ninths. Since there are three cards with one D each, the probability of selecting a D on the first draw is 1/3. Since the cards are replaced, the probability of selecting a D on the second draw is also 1/3. Therefore, the probability of selecting D and D in that order is (1/3) * (1/3) = 1/9. However, since the order of selection does not matter, we must also consider the probability of selecting D and D in the reverse order, which is also 1/9. Therefore, the total probability is 1/9 + 1/9 = 2/9.

The answer to Question 5 is four thirty sixths or one ninth. The only ways to get a sum of 5 are by rolling a 1 and a 4, a 2 and a 3, or a 3 and a 2. Each of these outcomes has a probability of 1/6 * 1/6 = 1/36, so the total probability is 3 * 1/36 = 1/12 = 4/36.

The answer to Question 6 is Rolling a number cube twice.  For example, WW represents rolling a 6 or higher on both rolls, and LL represents rolling a 5 or lower on both rolls.

Therefore, The sample space lists all possible outcomes of rolling a number cube twice, where W represents a roll with a value of 6 or higher, and L represents a roll with a value of 5 or lower.

What is arithmetic operation?

A subject of mathematics known as arithmetic operations deals with the study and use of numbers in all other branches of mathematics. Basic operations including addition, subtraction, multiplication, and division are included.

To calculate the increase in pay, start by multiplying the current hourly rate of $12.50 by the percentage increase of 8% -

Increase in pay = $12.50 x 8/100

Increase in pay = $12.50 x 0.08

Increase in pay = $1.00

So, the increase in pay is $1.00 per hour.

To find the new hourly rate after the increase, add the increase in pay to the current hourly rate -

New hourly rate = $12.50 + $1.00 = $13.50

Therefore, the increased, pay will be $13.50/hr.
