Answer:

Slope (m) = -5

Step-by-step explanation:

<em>*If all the given four points are on a straight line then; the slope derived from first two points should be equal to the slope derived from the next to points.</em>

<em />

Let's verify this ...

<u>For the first two points:</u>

Slope (m) = change in y ÷ change in x = \frac{6 - 11}{14 - 13} = \frac{-5}{1} = -5

<u>For the next two points:</u>

<u />

m = \frac{-4 - 1}{16 - 15} = -5

*Proved ∴ points (13,11) , (14,6) , (15, 1) and (16,-4) are on the same line.

  • <em>We can find the equation of this line and ascertain that the four points are on a single line.</em>

<em></em>

Taking another point (x,y) on the line and point (13,11);

m = \frac{y - 11}{x - 13} = -5

y = -5x + 65 + 11

y = -5x + 76

  • Let's graph this equation. (graph attached)

Answer:

Step-by-step explanation:

You can easily find the slope by using two points. Let’s use (13, 11) and (14, 6)

We look at the slope equation as: y2 - y1 divided by x2 and x1.

13 = x1 11= y1 and 14= x2 6=y2

Plug in: 6-11/14-13 and solve

Answer: -5

Hope I made sense :)

The owner of a small pet supply store wants to open a second store in another city, but he only wants to do so if more than one-
Andrei [34K]

Answer:

The answer is "The null hypothesis was rejected".

Step-by-step explanation:

Following are the right-tailed test:

Calculating the null and alternative hypothesis:

H_0 : p = 0.3333\\\\H_a : p > 0.3333\\\\n = 150\\\\x = 64\\\\\hat{p} = \frac{x}{n} = \frac{64}{150} = 0.4267\\\\P_0 = 0.3333\\\\1 - P_0 = 1 - 0.3333 = 0.6667\\\\

z = \frac{\hat{p} - P_0}{[\sqrt{\frac{P_0 \times (1 - P_0 )}{n}}]}

   = \frac{0.4267 - 0.3333}{[\sqrt{\frac{(0.3333 \times 0.6667)}{150}}]}\\\\= 2.426

Calculating the right-tailed test:

P(z > 2.426) = 1 - P(z < 2.426) = 1 - 0.9924 = 0.0076\\\\P-value = 0.0076\\\\\alpha = 0.05\\\\P-value < \alpha

Therefore, we reject the null hypothesis.

This example shows that more than a third of the families own pets in this town.

How can i use substraction to describe divison? <br> I’ll mark u as the brainliest
makvit [3.9K]
Repeated subtraction is a method of subtracting the equal number of items from a larger group. It is also known as division. If the same number is repeatedly subtracted from another larger number until the remainder is zero or a number smaller than the number being subtracted, we can write that in the form of division

David hikes 2 ¼ miles in ½ an hour at this rate, how long will it take him to walk 18 miles?
8090 [49]
So in 30 min will hike 2 1/4 miles =9 of those 1/4 miles therefore in 10 min will hike 9/3 =3 of those 1/4 miles = 3/4 of a mile

3/4 mile in 10 min;
(3/4)• 4 = 3 miles in 40 min;
6 miles in 80 min;
9 miles in 120 min;
12 miles in 160 min;
15 miles in 200 min;
18 miles in 240 min or 4 hours
