Answer:

G 52% to 60%

Explanation:

The percentage of voters that plan to vote Yes = 56%

The survey's margin of error = +/-4%

Therefore, the range for the percentage of voters who plan to vote Yes is:

\begin{gathered} 56\%\pm4\% \\ =56\%-4\%\text{ to }56\%+4\% \\ =52\%\text{ to }60\% \end{gathered}

The correct choice is G.

b) If the family decides to send their child to a 4-year public college, they will spend \$7500 per year

c) Valnez family will be pay \$12517 per year to raise the child from birth to 18 years old

d) \$15714 is the cost per year of raising a child from birth to 18 years old, and paying for 4 years of private college

Step-by-step explanation:

Part a) How much will the Smith family spend per year to raise their child from 5 to 18 years old? Round to the nearest dollar.

The cost from 5 to 18 years old is $145,700

Per year cost will be:

Divide the total amount by the number of years from 5 to 18 years. i.e 18-5 = 13 years

Cost per year: \frac{145700}{13}

Cost per year:\$11208

So, Smith family spend  \$11208 per year to raise their child from 5 to 18 years old.

Part b) If the family decides to send their child to a 4-year public college, how much will they spend per year?

The cost of 4 year Public College $30,000

Cost per year: \frac{30000}{4}

Cost per year: \$7500

So, If the family decides to send their child to a 4-year public college, they will spend \$7500 per year

Part c) How much will the Valnez family pay per year to raise the child from birth to 18 years old

Cost from Birth to 5 years old $79,600

Cost from 5 to 18 years old $145,700

Total\,\,cost = \$79,600+\$145,700\\Total\,\,cost =\$225300

Total years: 18

Cost per year: \frac{225300}{18}

Cost per year: \$12517

Valnez family will be pay \$12517 per year to raise the child from birth to 18 years old

Part d) What is the cost per year of raising a child from birth to 18 years old, and paying for 4 years of private college? Round to the nearest dollar.

From birth to 18 years (found in part c)

Cost from birth to 18 years: $225300

Cost of 4-year Private College: $120,400

Total Cost: \$225300+\$120,400

Total Cost: \$345700

Total years: 18+4 = 22

Cost per year: \frac{345700}{22}

Cost per year: \$15714

\$15714 is the cost per year of raising a child from birth to 18 years old, and paying for 4 years of private college

If y=8 when x=3 when x=45
Veronika [31]

Answer:

The value of y for x = 45 is 120 .

Step-by-step explanation:

Given as :

Let The variables y and x are proportional to each others

I,e y ∝ x

Now , y = k x

So, for x = 3  ,  y = 8

I.e  8 = k × 3           ........1

∴  k = \frac{8}{3}

<u>Similarly </u>

for x = 45 , y = k × 3

I.e y = k × 45        ..........2

Now, putting the value of k  in eq 2

So,  y =  \frac{8}{3} × 45

I.e y = \frac{8\times 45}{3}

Or, y = 8 × 15

∴    y = 120

So, for x = 45 , y = 120

Hence The value of y for x = 45 is 120 . Answer
