A researcher wants to know how undergraduate college students at her university feel about federal financial aid. She obtains a

list of 1196 undergraduate college students at her university, selects 500 of them at random, and emails a questionnaire to them. 107 questionnaires are returned. Of these, 71% stated that they believe that the federal student loan program needs to be completely overhauled. Classify the following groups as the population or the sample for this particular study. If a group does not belong in either category, leave it unplaced.

Answer:

The group she made is the Sample.

Here Population is the all students of undergraduate college at her university.

Whereas the selected 1196 undergraduate college students at her university as well as randomly selected 500 students are Sample.

<em>Further, </em>

<em>The </em><em>sample</em><em> is a subset of the population and it is easy to analyze as compared to the population. </em>

<em>The sample is said to be representative if it represents the whole population. </em>

Flauer [41]
<span>After 6 years of having 153 shares of Cawh Consolidated Banks, each of which pays a constant yearly dividend of $7.14, the value Carmen will receive in dividends is d. $6,554.52. This is the yearly dividend, so the value each of shares pays after 6 years is: $7.14 * 6 = $42.84. There are 153 shares and since each pays $42.84 after 6 years, the total value for all 153 shares after 6 years is: 153 * $42.84 = $6,554.52.</span>

Function f is a linear function with an initial value of 17 and a rate of change of –3. Some values for the linear function g ar
tia_tia [17]

Answer:

g(x) exceed f(x) by 10 when x=5

Step-by-step explanation:

step 1

Find the equation of function f(x)

we know that

The initial value is the y-intercept of the linear function (value of y when the value of x is equal to zero)

so

b=17

The rate of change is equal to the slope

so

m=-3

therefore

f(x)=-3x+17

step 2

Find the equation of function g(x)

Let

A(0,-8),B(2,0)

Find the slope

m=(0+8)/(2-0)=4

b=-8 ----> point A

therefore

g(x)=4x-8

step 3

Find the value of f(x) and g(x) for x=5

f(5)=-3(5)+17=2

g(5)=4(5)-8=12

Find the difference

g(5)-f(5)=12-2=10

Maria will spin the arrow on the spinner 2 times. What is the probability that the arrow will stop on the same letter twice? 19
gavmur [86]
Suppose the spinner lands on <em>a</em>.  There's a 1/3 chance that it'll land on <em>a</em> the second time.
Suppose the spinner lands on <em>b</em>.  There's a 1/3 chance that it'll land on <em>b</em> the second time.
Suppose the spinner lands on <em>c</em>.  There's a 1/3 chance that it'll land on <em>c</em> the second time.

We've covered all possibilities for the first spin, and they're all equal, so their average is 1/3.

The probability that it'll land on the same letter twice is 33.3%.

A pizza shop sells pizzas that are 10 inches (in diameter) or larger. A 10-inch cheese pizza costs
Bogdan [553]

Answer:

A pizza shop sells pizzas that are 10 inches orr larger. A 10-inch cheese pizza costs $8 and each additional costs $1.50 and each additional topping costs $0.75.

The equation that represents the cost of a pizza is:

P = $10 + $1.50a + $0.75b

Where 'a' represents the number additional inches and 'b' represents the number of additional toppings.
