Step-by-step explanation:
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches
Step-by-step explanation:
y= bisection of w and z
X= intersection of w and z
z= intersection of X and w
w= intersection of X and z
Answer:
F(x) = -3^(27)
According to the way the question was arranged, the answer above is the answer.
But the options given none of them matches my answer.
Step-by-step explanation:
A function is defined as (f of x)
= -3^4√x-9.
F(x)= -3^(4√x-9) at x= 81
√x= √81
√x= 9
F(x)= -3^(4(9)-9)
F(x) = -3^(36-9)
F(x) = -3^(27)
Answer:
x < 0
Step-by-step explanation:
If you look at the values of y, they get bigger ( less negative) when x is negative, when x is positive they get smaller
The function is increasing when x<0
