Answer: The following statements are correct :

Data are typically collected from a sample because it is too difficult and expensive to collect data from an entire population.

When the results from a sample are extended to the​ population, it is called inference.

If data are not collected​ properly, the conclusions that are drawn will be meaningless.

The following statement is false: <u><em>The first step in the process of statistics is to collect the data.</em></u>

The first step in the process of statistics is to <em><u>Plan: develop a statistical inquiry that can be answered with aggregation of data.</u></em>

seraphim [82]

Answer:

245.04

Step-by-step explanation:

The equation to a cylinder for area is A=2πrh+2πr^2

Fill in and solve.

A=2(3.14)(3)(10)+2(3.14)(3)^2

So using PEMDAS you get the answer 245.04

Find three consecutive even integers if three times the first integer is two times<br> the third
lara31 [8.8K]

Solution:

Let's name the three consecutive numbers as y, y + 2, and y + 4.

<u>Note that:</u>

  • => Equation formed: 3(y) = 2(y + 4)

<u>Solve the equation to find the three consecutive numbers.</u>

  • 3(y) = 2(y + 4)
  • => 3y = 2y + 8
  • => 3y - 2y = 8
  • => y = 8

The numbers are 8, 10, and 12.

1. Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year
Zielflug [23.3K]

Answer:

The value after 7 years is $ 855355.65

Solution:

Given that, Annual sales for a fast food restaurant are 650000 and are increasing at a rate of 4% per year

To find:  exponential function to find the annual sales after 7 years

The exponential growth function is given as:

Where,

"a" is the initial amount

"y" is the future value

"r" is the rate of interest in decimal

"t" is the number of years

Here in this given question,

a = 650000

t = 7 years

Substituting the values in given formula,

Thus the value after 7 years is $ 855355.65

A globe has a surface area of 2700 cm². Andrew wants to estimate the volume of the globe. To do the estimate, he approximates π
Alika [10]
The surface area is given by:
 A = 4πr ^ 2
 Where,
 r: sphere radio
 Substituting values we have:
 2700 = 4 (3) r ^ 2
 Clearing r we have:
 r = root (2700/12)
 r = 15
 Then, the volume of the sphere is given by:
 V = (4/3) πr ^ 3
 Substituting values:
 V = (4/3) * (3) * (15) ^ 3
 V = 13500 cm ^ 3
 Answer:
 
The approximate volume of the globe is:
 
V = 13500 cm ^ 3
