Well there are 5280 feet in 1 mile and if you multiply that by 2 then that's too many. if you multiply 5280 by 1.5, then you get 7920 so it is equal to 1.5 miles.

There are 36 inches in 1 yard so you multiply 6 by 36 to get 216.

Again there are 5,280 feet in 1 mile. Divide 26,400 by 5,280 and you get 50 miles.

12 inches in 1 foot. Multiply 12 by 9 and get 144.

22 feet equals 7 yards and 1 foot.

51 inches equals 4 feet and 3 inches. (4 feet equals 48 inches)

Btw, 7 yards is greater then 20 feet (7 yards equals 21 feet)

2 miles is more then 3,500 yards. (2 miles equals 2,520 yards)

11.5 feet is less then 4 yards (4 yards equals 12 feet)

72 inches is EQUAL to 2 yards

5.5 yards is more then 192 inches. (5.5 yards equals 198 inches)

antiseptic1488 [7]

Answer:

The statistical conclusion is:

a) Your results are significant; one's willingness to wear masks is not independent of one's age.

Step-by-step explanation:

From this experiment,

The null hypothesis is established as:

H 0 = one's willingness to wear masks is independent of one's age.

The alternate hypothesis is established as:

H 1 = one's willingness to wear masks is not independent of one's age.

In statistics, if the absolute value of the test statistic is greater than the critical value, we declare statistical significance and reject the null hypothesis.

Since the test statistic = 16.5, which is higher than the critical value of 7.82, this establishes statistical significance. Thus, the null hypothesis is rejected.

Therefore, the statistical conclusion is that one's willingness to wear masks is not independent of one's age.

X y

Darina [25.2K]

Answer:

Part 1) The rate of change is $\frac{17}{15}$

Part 2) The initial value is 68

Part 3) The function rule to the linear model is $y=\frac{17}{15}x+68$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

step 1

Find the slope

take two points from the table

(0,68) and (15,85)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{85-68}{15-0}$

$m=\frac{17}{15}$

In a linear function , the slope is the same that the rate of change

therefore

The rate of change is $\frac{17}{15}$

step 2

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

Looking at the table

For x=0, y=68

therefore

The y-intercept is

$b=68$

The y-intercept is also called the initial value

therefore

The initial value is 68

step 3

Determine the function rule to the linear model

$y=mx+b$

we have

$m=\frac{17}{15}$

$b=68$

substitute

$y=\frac{17}{15}x+68$
