answer:

the mean for this is 27

step-by-step explanation:

all you have to do is add up all of the times

15, 18, 20, 22, 28, 37, 49

which would have given you

189

then you divide that number by how much times were written down

7 would be that number so

189/7 = 27

and this is what it is written in one equation

(15+18+20+22+28+37+49)/7

hope this helps you! :)

What is the answer to y = 0.0793x + 31.3

SIZIF [17.4K]

Answer:

a line :P

Step-by-step explanation:

This is the slope intercept form of a line.

the formula is.....

y = mx + b

so that equations will make a line... that goes through 31.5 as it passes over the y axis... in a Cartesian graph... hmmmmm do they want you to draw it?

It would be hard to draw b/c of the 0.079 slope part.. but.. it's very very slightly going up hill... from 31.5....

A company makes two different-sized ice cream cones. The smaller cones are 3.5 inches tall and have a diameter of 3 inches. The

barxatty [35]

Answer:

The Volume of large cone is 19.545 $inches^3$ greater than the smaller cone

Step-by-step explanation:

Given:

Size of the small cone = 3.5 inches

Diameter of the small cone = 3 inches

Size of the large cone = 3.5 inches

Diameter of the small cone = 3 inches

To Find:

How much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone = ?

Solution:

Volume of the small cone :

Radius = $\frac{diameter}{2}$

Radius = $\frac{3}{2}$

Radius = 1.5 inches

volume of the cone = $\pi rl$

substituting the values,

=> $\pi (1.5)(3.5)$

=> $\pi(5.25)$

=> 16.485 $inches^3$

Volume of the large cone :

Volume of the large cone :

Radius = $\frac{diameter}{2}$

Radius = $\frac{4.5}{2}$

Radius = 2.25 inches

volume of the cone = $\pi rl$

substituting the values,

=> $\pi (2.25)(5.1)$

=> $\pi(11.475)$

=>36.06 $inches^3$

Now ,

volume of small cone - volume of large cone

=>36.06 - 16.485

=>19.545 $inches^3$

2) A fair coin was tossed 75 times. The coin landed on Heads 42 times and Tails 33 times. What is the experimental probability o

coldgirl [10]

Answer:

$\frac{11}{25}$

Step-by-step explanation:

In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...

$\frac{33}{75}$ or 0.44

This fraction can also be simplified to its simplest form of $\frac{11}{25}$ which is obtained by dividing both the numerator and denominator by 3
