<em>The expected value of n is 1.152</em>

The question states that ratio of 2n+2 and 2n-2 = 99:7. This means that

2n+2:2n-2 = 99:7, this also means that

\frac{2n+2}{2n-2} = \frac{99}{7}

If that is so, we can cross multiply so that

99 * (2n - 2) = 7 * (2n + 2), on expanding the bracket, we have

198n - 198 = 14n + 14

198n - 14n = 14 + 198

184n = 212, dividing both sides by 184, we have

n = 212/184

n = 1.152

<u><em>Therefore, the value of n is 1.152</em></u>

A bathtub can hold 80 gallons of water. The faucet flows at a rate of 4 gallons per minute what percent of the tub will be fille
bazaltina [42]

Answer:

After 6 minutes the tub will be 30% full

Step-by-step explanation:

Step 1

Determine the total volume that will be filled by the faucet at time (t) using the expression below;

V=R×T

where;

V=total volume

R=flow rate, gallons per minute

T=time in minutes

In our case;

V=unknown

R=4 gallons per minute

T=6 minutes

replacing;

V=4×6=24 gallons

Total volume filled after 6 minutes=24 gallons

Step 2

Determine the percentage volume of the tab that will be filled after 6 minutes using the expression;

percentage volume=(volume filled after 6 minutes/total volume)×100

where;

volume filled after 6 minutes=24 gallons

total volume=80 gallons

replacing;

percentage volume=(24/80)×100=30%

After 6 minutes the tub will be 30% full

LAST QUESTION PLEASE HELP IF YOU CAN FOR 11 POINTS AND BRAINLIEST + THANK YOU
jekas [21]

Answer:

  see attachment

Step-by-step explanation:

The y-intercept is +4 for both lines, so only the third selection is appropriate. The lines appear to have a slope of magnitude less than 1, so ±1/2 seems about right.

(We expect at least one of the inequality symbols to include the "or equal to" case so there is no hole at x=0. Alas, it seems the third answer choice doesn't do that.)
