a, d, f
Step-by-step explanation:
Answer:
a. 0.50
Step-by-step explanation:
The standard error of the mean is the standard deviation of the population divided by the square root of the sample size.
In this problem, we have that:
Standard deviation of the population: 6 hours
Sample size: 144
Square root of 144 is 12.
So the standard error of the sample mean is 6/12 = 0.5.
Answer:
1/2 = 3/6
1/3 = 4/12
1/5 = 2/10
1/4 = 5/20
Step-by-step explanation:
To make equivalent fractions, you need multiply by 1. A number divided by itself is 1.
1/1 * x/x = x/x = 1
1/2 = 3/6
1/3 = 4/12
1/5 = 2/10
1/4 = 5/20
Hope this helps :)
Have a great day!

Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
