Answer: -10 + 144
Step-by-step explanation:
Subtract alike terms (2x -12x) since the 144 does not have a variable you cannot subtract it
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
Answer:
He ate 42 of the 90 grapes in the bowl
The percentage of grape he ate will be given as this:
42/90 * 100%
=46.67%
Tyler has ate 46.67% of the grapes
Answer:
18
Step-by-step explanation:
-74 --92 =
-74 + 92 =18
-56 --74
-56 + 74 = 18
-38 --56
-38+56 = 18
we are adding 18 each time
The common difference is 18
Answer: m=44
Step-by-step explanation:
1/2m-3/4n = 16
1/2m-3/4(8) = 16
1/2m-24/4 = 16
1/2m-6 = 16
1/2m = 22
m=44
