A school survey found that 7 out of 30 students walk to

nika2105 [10]

Answer: 7/145

Step-by-step explanation:

The probability that the first student walks to school will be: = 7/30.

The probability of selecting the second student that walks to school will be: = 6/29.

Then we multiply both together and this will be:

= 7/30 × 6/29

= 7/145

1. Over 3 years, how much more does $3000 in a savings account with an APR of 3.2% compounded

Sedbober [7]

Answer:

$1080

Step-by-step explanation:

$((3000 \times 0.032) \times 2) \times 3 = 576$

convert % to decimal by multiplying 3.2%x100=0.032

then multiply by initial amount 3000x0.032

then multiply by 2 because it's compounding semiannual

then multiply by 3 because it's over a 3 yr period

do the same for the quarterly compound but multiply by 4 because it's quarterly

$((3000 \times 0.03) \times 2) \times3 = 1080$

over a 3 yr period the quarterly compounded amount will earn:

$1080 - 576 = 504$

$504 more than the account compounded semiannual

A wheel with radius 1 foot makes 1 revolution in 4 seconds. What is the linear velocity, in feet per second, of a point on the e

Alona [7]

In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.

The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.

Then the point has a linear speed of

(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s

I=prt,for p please show step by step for this variable

Bond [772]

Answer:

$p = \dfrac{I}{rt}$

Step-by-step explanation:

I = prt

Switch sides.

prt = I

We are solving for p. We want p alone on the left side. p is being multiplied by r and t, so we divide both sides by r and t.

$\dfrac{prt}{rt} = \dfrac{I}{rt}$

$p = \dfrac{I}{rt}$
