Answer:

Erin

Step-by-step explanation:

Z score formula:

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Candice:

Z score = 74 -66/4

Z score = 2

For Erin

Z score = 58 - 42/7

Z score = 2.28571

Erin z score is larger hence, he did better

An investor plans to invest $500 a year and expects to get a 10.5% return. If the investor makes these contributions at the end
taurus [48]

The present value of the investment is $6000.

According to the statement

Principal amount = $500

By the formula

PV = P[1-(1+r)^n]/r

PV = 500[1-(1+0.10)^20]/0.10

PV = 6000

So, The present value of the investment is $6000.

What was your speed if you drove 325 miles in 5 1/4 hours?
Alexus [3.1K]

Answer:

62 miles per hour speed if you drove 325 miles in 5 1/4 hours

Step-by-step explanation:

Using formula:

\text{Speed} = \frac{\text{Distance}}{\text{Time}}

As per the statement:

if you drove 325 miles in 5 1/4 hours

⇒\text{Distance}=325 miles

and

Time = 5\frac{1}{4} = \frac{21}{4} = 5.25 hours

Then by above formula we have;

\text{Speed} = \frac{325}{5.25}=61.90 miles per hour

Therefore, 61.90 ≈ 62 miles per hour speed if you drove 325 miles in 5 1/4 hours

In a right triangle, the hypotenuse is 5 units long, and the legs also have integer lengths. How long are the legs?
Drupady [299]
5^2 = a^2 + b^2

25 = a^2 + b^2
 the other sides need to be shorter than 5 so plug them and and see what works:

25 = 4^2 +4^2 = 25 = 16+16 = 25 = 32 false

25 = 4^2 + 3^2 = 16+9 = 25, 25 = 25 True

 the only one that works would be sides of 3 and 4 units long
