Answer:
18.75 PLEASE GIVE BRAINLIEST
Step-by-step explanation:
8 hours = 30 gallons
30 ÷ 8 = 3.75 gallons of water used per hour
3.75 x 7 = 26.25 gallons used in 7 hours
45 - 26.25 = 18.75 gallons left after 7 hours

Answer:
3 < x < 6
Step-by-step explanation:
1) Subtract 2 from the whole equation.
- 13 - 2 > -5x > -28 - 2
2) Simplify.
-15 > -5x > -30
3) Divide the whole equation by -5.
-15/-5 < x < -30/-5
4) Simplify.
3 < x < 6

Answer with explanation:</h2>
Given : The distribution of the lengths of a commercially caught fish is bell-shapped ( i.e. normally distributed ) with and .
Let x be the length of a commercially caught fish .
Any fish measuring less than 20 cm must be released.
1) The probability that a fish measuring less than 20 cm :
∴ The proportion of fish that must be released is about 0.16.
2) The probability that a fish measuring between 20 cm and 32 cm :
If total 500 fish are caught, then number of fish have lengths between 20 cm and 32 cm = 0.8185 x (500)=409.25 ≈409
The nearest option from the given options is "408".
