Answer:
Area = 9π sq. m.
Step-by-step explanation:
C = πd
6π = πd
d = 6
r = 3
A = π
= π
= 9π sq. m.
M<ABC = m<EBD = 36 (vertical angles)
78 - x + 36 + 3x - 10 = 180 (straight angle)
Now solve for x
78 - x + 36 + 3x - 10 = 180
2x + 68 = 180
- 68 -68 (subtract 68 on both sides)
2x = 58
x = 29
Scientists need technology to figure out other stuff. For example, A computer is used to research.
Answer: d. np(1 - p).
Step-by-step explanation:
Let x be any binomial variable which represents the number of success such that
, where n is the sample size or the total number of trials and p is the probability of getting success in each trial .
Then, the mean E(x) and the variance Var(x) for the binomial distribution is given by equation :


where n is the sample size or the total number of trials and p is the probability of getting success in each trial .
Therefore , the correct option is option d. np(1 - p) .
Answer:
Width is 10 Length is 20
Step-by-step explanation:
Perimeter = 60
Length = W + 10
P = 2L + 2W Write the equation for perimeter
60 = 2(W + 10) + 2W Substitute your variables
60 = 4W + 20
- 20 - 20 Subtract 20 from both sides
40 = 4W Divide both sides by 4
10 = W
