Answer:

1)Yes, because the difference in means ÷ by the larger MAD is greater than 2 MADs.

Step-step explanation:

Difference in means:

70.5 - 64.1

= 6.4

Larger MAD:

1.7

6.4/1.7 = 3.764705882 > 1.7

A cylinder has a base diameter of 10cm and a height of 14cm. What is its volume in cubic cm, to the nearest tenths place?

Dvinal [7]

Volume of any cylinder = π times (radius)² times (height or length)

Radius of your cylinder = 1/2 of the diameter =5 cm

Volume = π (5 cm)² (14 cm) = 350 π cm³ = 1,099.56 cm³ (rounded)

There were 2,300 applicants for enrollment to the freshman class at a small college in the year 2010. The number of applicants h

Answer:

The inverse function is $g(x) = \frac{x - 2300}{170}$

The value of g(x) represents the number of applicants to the freshman class based on the number of years since 2010.

Step-by-step explanation:

Number of applicants in x years after 2010:

Is given by the following function:

$f(x) = 2300 + 170x$

Inverse function:

We exchange the values of y = f(x) and x in the original function, and then find y. So

$x = 2300 + 170y$

$170y = x - 2300$

$y = \frac{x - 2300}{170}$

$g(x) = \frac{x - 2300}{170}$

The inverse function is $g(x) = \frac{x - 2300}{170}$

Meaning of g:

f(x): Number of students in x years:

g(x): Inverse of f(x), is the number of years it takes for there to be x applicants, so the answer is:

The value of g(x) represents the number of applicants to the freshman class based on the number of years since 2010.
