Answer:
c^2 = 6^2 -8
Step-by-step explanation:
The square of c is c^2; the square of 6 is 6^2. for the former to be 8 less than the latter, we must have ...
c^2 = 6^2 -8
A=(a+b/2) x h
a = 8
b = 14
h = 14
(8+14/2) x 14
(22/2) x 14
11 x 14 = 154
The answer is 154
Answer:
0.5818
Step-by-step explanation:
Suppose the average teenage romantic relationship is normally distributed with a mean number of 100 days with a standard deviation of 30 days.
Answer:
The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and if it is negative then it is below the mean. It is given by:

Given that:

Therefore, from the normal distribution table, P(90 < x < 150) = P(-0.33 < z < 1.67) = P(z < 1.67) - P(z < -0.33) = 0.9525 - 0.3707 = 0.5818
Answer:
i hope its correct
Step-by-step explanation:
11x + 2y=68 ------------1
5x+y=13 ------------2
y= 13-5x. ------------3
put 3 into 1
11x +2(13-5x) =68
11x +26 -10x =68
x=42
put x =42 into 2
5(42) +y =13
210+y=13
y=13-210
y=197
1/4 (6 + s)
One-fourth (1/4) of the sum (+) of: 6 and s (6 + s)
