Answer:

1,400

Step-by-step explanation:

We take the sample proportion of skunks and estimate for the entire population.

Sample:

140 skunks out of 230 + 140 + 120 = 490 animals.

140/490 = 0.28571428571

If a random sample of 5,000 animals are trapped in the city, how many skunks would be estimated to be included?

0.28571428571 out of 5000. So

0.28571428571*5000 = 1429

Close to 1400, which means that the answer is given by option C.

Maria has decided to invest to help with her retirement savings. How much would she have to invest to have $113,400 after 20 yea

Answer:

$56,226

Step-by-step explanation:

x = investment

Earning interest of 3.57% is the equivalent of multiplying the initial balance (investment) by 1.0357;

Over 20 years, the new balance can be found by multiplying the initial balance by (1.0357)²⁰;

We can formulate an equation to solve to get the initial investment:

x(1.0357)²⁰ = 113400

(2.01687752)x = 113400

x = ¹¹³⁴⁰⁰/₍₂.₀₁₆...₎

x = 56225.5263 → 56226

5p - 14 = 8p + 4<br><br> Explain

grigory [225]

1: we bring all the x to one member, changing its sign (I use x, consider it a p)
$5x - 8x - 14 = + 4$

2 we bring all the non-x to the other member
$5x - 8x = + 14 + 4$
3 we solve the members
$(5 - 8)x = - 3x$
$( + 14 + 4) = + 18$
4 we divide 18 by -3
$- 3x = + 18$
$x = 18 \div - 3$
$18 \div - 3 = - 5$
$x = - 5$
my English is so bad lol
