Answer:

2: 4

3:32

Step-by-step explanation:

so you are first going to solve in the parentheses and then solve the exponents

the simplest ratio of the Squares to the circle is 4:1.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, There are 16 squares and 4 circles.

Since there are 16 squares for 4 circles

The ratio of the Squares to the circle = 16/4

The ratio of the Squares to the circle = 4/1

Therefore, the simplest ratio of the Squares to the circle is 4:1.

Step-by-step explanation:

Hey there!

Given;

Ratio = 9:8:7

Let "x" be the common factor. So,

9x+8x+7x = 144

or, 24x = 144

or, x = 144/24

or, x= 6

It's like;

= 9*6:8*6:7*6

= 54:48:42

Therefore, their ratio is 54:48:42.

Answer:

p - 3

Step-by-step explanation:

"fewer than" means subtract from, in this case 3, from an unknown number represented by p

The expression represents the phrase: “3 fewer than a number, p" is

(p-3).

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

We have,

Statement - “3 fewer than a number, p”

We know that the symbol for fewer would subtraction.

Then, the mathematical expression for 3 fewer than a number, p is

= (p - 3)

Thus, the required expression is (p-3).

Answer:

y=x+1

Step-by-step explanation:

The first step I took was to find the slope. A slope is equal to the rise over the run. The equation goes up 2 for every 2 it goes over, which means that the slope is 2/2 or 1. Then you need to determine the y intercept. I usually go about this by thinking logically about the problem. Because there is a point at (4,5) and the slope is 1, there must also be a point at (3,4) (2,3) (1,2) and (0,1) Because the x value in (0,1) is 0, we know that the y intercept must be 1, so I added 1 to the equation. The last step is putting it all together. We know that a linear equation is y=mx+b (m being the slope, b being the y-intercept) so the final equation is y=x+1

The proportional relationships that have the same ratio to that of mike and randys age include:

Since Mike is 5 years old and Randy is 8 years old, their ratio is 5:8.

Also, since Sarah is 40 years old and her mother is 64 years old. We can divide their ages by 8. Then the ratio will be 5:8.

Phill is 40 years old and Moleka is 25 years old. We can divide their ages by 5. Then the ratio will be 5:8.

Complete  Question

An online poll has a question that appears on the screen, and you simply click buttons to vote "Yes, " "No, " "Not sure, " or "Don't care." On a particular day, the results of a question were tallied. In all, 636 said "Yes, " another 595 said "No, " and the remaining 93 indicated that they were not sure.

a)

What is the sample size for this poll?

b)

Compute the percent of responses in each of the possible response categories. (Round your answers to two decimal places.)

c)

Discuss the poll in terms of the population and sample framework that we have studied in this chapter.

i)

This random sample of responses collects the opinions of a random group of users across all users of the Internet.

ii)

This voluntary response sample collects only the opinions of those that visit this site every day.

iii)

This random sample of responses collects the opinions of a random group of users of the particular site.

iv)

Answer:

a

   [tex]n  =  1324[/tex]

b

  YES             [tex]y  = 48.03 \% [/tex]

    NO             [tex]m  =44.94 \% [/tex]

   NOT SURE  [tex]m  =7.02\% [/tex]

c

The correct option is (iv)

Step-by-step explanation:

From the question we are told that

The voting options are "Yes, " "No, " "Not sure, " or "Don't care."

The number of people that said is [tex]Y = 636[/tex]

The number of people that said No is [tex]N = 595 [/tex]

The number that indicated Not sure is [tex]S = 93[/tex]

Generally the sample size is mathematically represented as

[tex]n = Y + N + S[/tex]

=> [tex]n = 636 + 595 + 93[/tex]

=> [tex]n = 1324[/tex]

Generally the percentage of responses that was Yes is mathematically represented as

[tex]y = \frac{636}{ 1324} * 100[/tex]

=>     [tex]y  = 48.03 \% [/tex]

Generally the percentage of responses that was No is mathematically represented as

[tex]m = \frac{595}{ 1324} * 100[/tex]

[tex]m =44.94 \% [/tex]

Generally the percentage of responses that was Not sure is mathematically represented as

[tex]s = \frac{93}{ 1324} * 100[/tex]

[tex]m =7.02\% [/tex]
