YOU HAVE TO FIND THE SLOPE m

The formula to find the slope is m=(y₂-y₁)/(x₂-x₁)

Since we have the coordinate of each point, then we can calculate the slope m

7) (-6-3)/(2+4) = -9/6 =-3/2 (slope negative so the function falls

8) (-1-1)/(7-7) = -2/0 (tan ---> ∞ ) VERTICAL

9) (-2+2)/(5-3) = 0/2 = 0 slope = 0 ===> Horizontal

In a random sample of 5 residents of the state of Texas, the mean waste recycled per person per day was 1.9 pounds with a standa
sammy [17]
<h2>Answer with explanation:</h2><h2 />

The confidence interval for population mean is given by :-

\overline{x} \pm\ t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 5, since n<30 , so the test we use here is t-test.

Sample mean : \overline{x}=1.9\text{ pounds}

Standard deviation: \sigma=0.89\text{ pounds}

Significance level : 1-\alpha:1-0.99=0.01

By using the standard normal distribution table , the critical value corresponds to the given significance level will be :-

t_{n-1,\alpha/2}=t_{5-1,0.01/2}=t_{4,0.005}=4.604

Now, the 99% confidence interval for the mean waste recycled per person per day for the population of Texas will be :-

1.9\pm\ (4.604)\dfrac{0.89}{\sqrt{5}}\\\\\approx1.9\pm1.832\\\\=(1.9-1.832,1.9+1.832)=(0.068,\ 3.732)

Hence, the 99% confidence interval for the mean waste recycled per person per day for the population of Texas  = (0.068, 3.732)

A class consists of 23 women and 83 mean. If a student is random selected, what is the probability that the student is a woman?
slavikrds [6]

Answer:

P(Woman) = \frac{23}{106}

Step-by-step explanation:

Given

Women = 23

Men = 83

Required

P(Woman)

This is calculated as the number of women divided by the population of the class

i.e.

P(Woman) = \frac{Women}{Women + Men}

So, we have:

P(Woman) = \frac{23}{23+83}

P(Woman) = \frac{23}{106}

A. -7x+5<br> B. -7x-35<br> C. -7x+35<br> D. x-35
liubo4ka [24]

Answer:

B

Step-by-step explanation:

p(x) = r(x) * s(x)

     = (x + 5) *(-7)       {Use distributive property}

    = x * -7 + 5 * -7

    = - 7x - 35
