Since the smaller pyramid's height is 6 and the larger pyramid's height is 12, the scale factor is 6/12=1/2
The scale factor for the base would be (1/2)^2 (since we're multiplying the sides, and each of them has a scale factor of 1/2)=1/4
For the volume, since we add another side with scale factor 1/2, we multiply 1/4 by 1/2 to get 1/8
The probability that exactly 1 doesn't grow will be 0.07
<h3> What is Probability?</h3>
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We can use Bernoulli estimation to solve this. P(g) = 0.85, probability of not growing into healthy plant P(n) = 1-P(g) = 1 - 0.85 = 0.15
Using the Bernoulli approximation:
P(n=1)=⁹C₁xP(n)¹.⁵xP(g)⁸.⁵
P(n=1)=9x0.15¹.⁵x0.8⁸.⁵
P(n=1)=0.07
Hence the probability that exactly 1 doesn't grow will be 0.07

Answer:
42
Step-by-step explanation:
Trapezoid has 4 lines
If each side increase by 7, 4 lines totally increase by 7*4 = 28
Perimeter will be 14 + 28 = 42
