Answer:

15). is done

16).

slope =  \frac{ {y}^{1} -  {y}^{o}  }{ {x}^{1}  -  {x}^{o} }  \\  =  \frac{2 - ( - 2)}{ - 3 - 9}  \\  =  \frac{4}{ - 12}  \\ slope =  -  \frac{1}{3}

A safety officer wants to prove that μ = the average speed of cars driven by a school is less than 25 mph. Suppose that a random
Akimi4 [234]

Answer:

t=\frac{24-25}{\frac{2.2}{\sqrt{14}}}=-1.70    

The degrees of freedom are given by:

df=n-1=14-1=13  

The p value for this case would be given by:

p_v =P(t_{(13)}  

Step-by-step explanation:

Information given

\bar X=24 represent the mean height for the sample  

s=2.2 represent the sample standard deviation

n=14 sample size  

\mu_o =25 represent the value that we want to test

t would represent the statistic

p_v represent the p value for the test

Hypothesis to verify

We want to cehck if the true mean is lees than 25 mph, the system of hypothesis would be:  

Null hypothesis:\mu \geq 25  

Alternative hypothesis:\mu < 25  

The statistic would be given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

Replacing the info given we got:

t=\frac{24-25}{\frac{2.2}{\sqrt{14}}}=-1.70    

The degrees of freedom are given by:

df=n-1=14-1=13  

The p value for this case would be given by:

p_v =P(t_{(13)}

line v has an equation of y=10/9x +1. Line w includes the point (-3,3) and is perpendicular to line v. What is the equation of l
NARA [144]

Answer:

y = -9/10x + 3/10 or y = 3/10(1 - 3x)

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals of one another

so slope of line w is -9/10

Using (-3,3) >> y = -9/10x + b

3 = -9/10(-3) + b

3 = 27/10 + b

b = 3 - 27/10 = 30/10 - 27/10 = 3/10

y = -9/10x + 3/10 or y = 3/10(1 - 3x)

Jenna surveyed her friends, asking each of them, "How many times have you been to the aquarium?" The resulting data set has a di
exis [7]

In the research, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.

<h3>How to illustrate the research?</h3>

It should be noted that when the distribution of data is skewed to the <u>left</u>, the mean is less than the median.

The distribution can be described by its center. If the distribution is skewed left or right, the <u>median</u> is an accurate measure of center.

The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.
