Answer:
X= -1
Step-by-step explanation:
So to solve equations like this, you want to isolate the variable first. Then you begin to simplify by dividing each side of the equation by a factor that does not contain a variable.
Answer:
x=0
Step-by-step explanation:
3*9+x=27-x [9^1=9]
27+x=27-x
27-27= x+x
2x=0
x=0
Answer:

And we can find the probability using the complement rule and with the normal standard table like this:

The probability that the mean height for the sample is greater than 65 inches is 0.007
Step-by-step explanation:
Let X the random variable that represent the women heights of a population, and we know the following parameters
and
We are interested on this probability
Since the sample size selected is 75>30 we can use the centrel limit theorem and the appropiate formula to use would be the z score given by:
If we find the z score for 65 inches we got:

And we can find the probability using the complement rule and with the normal standard table like this:

The probability that the mean height for the sample is greater than 65 inches is 0.007
Answer:
SA = 904 in.²
Step-by-step explanation:
Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)
SA = 2(lw) + 2(wh) + 2(hl)
- l = 36 in.
- w = 10 in.
- h = 2 in.
Substitute the given values and multiply:
SA = 2(lw) + 2(wh) + 2(hl)
SA = 2(36)(10) + 2(10)(2) + 2(2)(36)
SA = 2(360) + 2(20) + 2(72)
SA = 720 + 40 + 144
SA = 904 in.²
Hope this helps!
