Answer:
h(-6)= -(-6)2+1= 12+1= 13.
Answer:
25
Step-by-step explanation:
We know that the standard error of the sampling distribution of sample means is
Standard error=standard deviation/√n
√n=standard deviation/Standard error
n=(standard deviation/Standard error)²
We are given that standard deviation=5 and standard error=1. So,
n=(5/1)²
n=5²
n=25.
Thus, the required sample size is 25.
3(x + 7) = 9(x - 1)
3(x) + 3(7) = 9(x) - 9(1)
3x + 21 = 9x - 9
<u>- 3x - 3x </u>
21 = 3x - 9
<u>+ 9 + 9</u>
<u>30</u> = <u>3x</u>
3 3
10 = x

Answer: 1,500 liters or 396.2581 gallons
Step-by-step explanation: To figure out how much water flows every minute, you‘ll have to multiply 25 liters to 60, which is how many seconds are in a minute. Once, you multiply 25 to 60, you should get a final result of 1,500 or 1,500 liters.
*Reminder*: <u>You can convert 1,500 liters to gallons if you want, but only if your teacher allows you to.</u>
