You have 2 triangles and 3 rectangles.
Start with a triangle:
area is base side * height / 2 -> 4 * 3 / 2 = 6
The other triangle has the same area: 6
First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21
Now simply add all this together: 6+6+35+28+21 = 96
Answer:
Step-by-step explanation:
It would be the middle of the 6 and 5 because you go -4 plus to to the left and in half would be in the middle of that.
6-2x=-22
2x=-22-6
2×= -16
2x/2= -16/2
X= - 8
SO
six less than twice eight is -22

Step-by-step explanation:
Answer: The probability that it will break down in the next 21 days is 0.777
Step-by-step explanation:
Let the random variable x represent
time between breakdowns of a generator
Given that mean = 14 days,
Decay parameter, m = 1/14
The probability density function for exponential distribution is expressed as
F(x) = me-mx
It becomes
f(x) = 1/14e-(x × 1/14)
P(X < x) = 1 - e- mx
The probability that it will break down in the next 21 days is expressed as
P(x ≤ 21) = P(x < 21)
Therefore,
P(x < 21) = 1 - e-(1/14 × 21)
= 1 - e-1.5
= 1 - 0.223 = 0.777
P(x ≤ 21) = 0.777
