Answer: Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds. Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds. Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris. Which of the following represents the shape of the sampling distribution for x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C?

Normal, because both population distributions are Normal.  

Uniform, because the both sample sizes are less than 30.

Skewed right, because the difference in times cannot be negative.

Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

Step-by-step explanation: Can someone tell me the answer?

Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

Alex’s times for running a mile are Normally distributed with a mean time of 5.28 minutes and a standard deviation of 0.38 seconds.

Chris’s times for running a mile are Normally distributed with a mean time of 5.45 seconds and a standard deviation of 0.2 seconds.

Ten of Alex’s times and 15 of Chris’s times are randomly selected. Let x Overbar Subscript Upper A Baseline minus x Overbar Subscript Upper C represent the difference in the mean times for Alex and Chris.

The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.

Normal, because both population distributions are Normal.  

Uniform, because both sample sizes are less than 30.

Skewed right, because the difference in times cannot be negative.

Skewed left, because the sample sizes are less than 30 and the sampling variability is unknown.

Step-by-step explanation:

[tex]\frac{3}{11} = 0.2727272727[/tex]

27 is repeating so you draw a line over the number

Answer: 0.27 thats the answer hope you pass your grade

Answer:

The number of adults tickets sold equals 52.

Step-by-step explanation:

First, we need to establish the system of equations:

x= number of adults tickets sold

y= number of kids tickets sold

10x + 6y= 928

x + y=120

Now, we isolate x in one equation and change it in the other to obtain its value:

x= 120 - y

10(120 - y) + 6y = 928

1,200 - 10y + 6y = 928

272 = 4y

68 = y

x= 120 - 68= 52

Answer:

x=15

Step-by-step explanation:

it would be something like this:

f(x) = 12 + x(4%)

but if you want it in y format then:

y = 12 + x(4%)

Answer:

4d−3

Step-by-step explanation:

5d−7−d+4

Combine 5d and −d to get 4d.

4d−7+4

Add −7 and 4 to get −3.

4d−3

The simplified expression is 4d - 3.

Given is an expression 5d - 7 - d + 4 we need to simplify it,

We know that,

An expression is a combination of numbers, variables, and operations that can be evaluated to produce a value.

It can represent a mathematical relationship or a computation.

To simplify the expression 5d - 7 - d + 4, we can combine like terms.

First, let's group the terms with the variable "d" together:

(5d - d) - 7 + 4

Simplifying within the parentheses:

4d - 7 + 4

Combining the constants:

4d - 3

Therefore, the simplified expression is 4d - 3.

Answer:

The vertex of the graph of g is 2 units above the vertex of the graph of f.

Step-by-step explanation:

The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.

Then the g(x) will be

g(x) = x² + 2

We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.

The graph is shown.

The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).

Thus, the correct option is A.

Answer:

the scale factor is penguin

jkjk the scale factor is 1/2

Step-by-step explanation:

to find the scale factor you take the coordinates of the image and divide it by the coordinates of the preimage

ex. A' coordinates are (3,1)

A coordinates are (6,2)

3/6=1/2

1/2=1/2

therefore the scale factor is 1/2

Answer: 165 different combinations.

Step-by-step explanation:

Here we first need to identify the "selections", and then the number of options for each selection.

Here we have two selections, shorts, and sleeveless blouses.

For shorts, we have 15 options.

For sleeveless blouses, we have 11 options.

The total number of combinations will be equal to the product between the numbers of options for each selection, then the total number of combinations is:

C = 11*15 = 165

Answer:

[tex]m=\frac{2}{5}[/tex]

Step-by-step explanation:

1. To find the slope we need to use the slope formula, [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

2. The points that were given were (0,0) and (5,2). Let's plug those into the formula.

[tex]\frac{2-0}{5-0}[/tex]

[tex]\frac{2}{5}[/tex]

So, your slope would be [tex]m=\frac{2}{5}[/tex]

Answer:

shortest:  33 feet  

second:  66 feet

third:  58 feet

Step-by-step explanation:

s = shortest side  (33)

2s = second side   (66)

25 + s = third side   (58)

157 = s + 2s + 25 + s

157 = 4s + 25

4s = 132

s = 33

Lets us start with finding the inner angles of the triangle. The bottom right angle shall be 70 degrees as it is opposite. The 100 degrees shall add together to make 200. 360-200 = 160. 160 / 2 = 80. So, Now we know bottom left angle (80) and bottom right (70). 80 + 70 = 150. In a triangle, angles add to 180 so 180 - 150 = 30. 30 = 2x which means that x = 15
