How do u find a slope

Mathematics

To find slope, you do the height of the line over the length of the line. In other words, rise over run. If I have a line that is 5 units tall and 10 units in length, my slope would be 5/10, or 1/2.

Mileage tests are conducted for a particular model of automobile. If a 98% confidence interval with a margin of error of 1 mile
Llana [10]

Answer: 37

Step-by-step explanation:

Given : Significance level : \alpha:1-0.98=0.02

Critical value : z_{\alpha/2}=z_{0.01}=2.33

margin of error : E= 1 mile per gallon

Population standard deviation: \sigma=2.6 miles per gallon.

We know that when the population standard deviation is known then the formula to find the sample size is given by  :

n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2

n=(\dfrac{(2.33)\times 2.6}{1})^2=36.699364\approx37  [Round to the next whole number.]

Hence, the required number of automobiles should be used in the test = 37

The distance between two cities on a map is 4 - inches. The actual distance between the two cities is 24 miles.
Rudiy27

Answer

The scale factor is

Explanation

We have to ways to find the scale factor here:

1. Find the unit fraction from inches to miles; in other words, we need to divide the distance between the cities on the map (in inches) by the actual distance between the cities.

We can conclude that the scale factor is

2. Let  be the scale factor.

We know form our problem that 24 miles times the scale factor is equal 4 1/2 inches, so we can set up an equation an solve for :

Just like before, we can conclude that the scale factor is

B.

Answer

6 inches separate the cities on the map

Explanation

We know that our scale factor is 1/4 inch = 1 mile, so we can create a conversion factor to convert 24 miles to inches. Since we need to convert from miles to inches, the denominator of our conversion factor must be 1 mile so we can cancel miles out. Notice that we can also express 1/4 inch as 0.25 inch to simplify our calculations:

We can conclude that if the conversion factor is 1/4 inch = 1 mile, 6 inches separate the cities on the map.
