Delvig [45]

Answer:

The correct answer is 0.15

Step-by-step explanation:

According to the given scenario, the probability is as follows:

X\sim Bin (n,p)

Here

n = 8

p = 0.20 or 20%

Now this is a binomial probability distribution

P(X) = ^nC_x \times p^x \tmes (1 - p)^{n-x}\\\\P(3) = ^8C_3 \tims 0.20^3 \times (1 - 0.20)^5

= 0.15

Hence, the correct answer is 0.15

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −160 feet. Then she continued to hike down
RoseWind [281]
Ok so first, you need to figure out the change in elevation for each after one min. so we will write it as a ratio

10:-160        20:-300
So for the 10 min one, we will divide both sides by 10
1:-16      So the change in elevation per min. is -16
Now for the 20 one, we will divide by 20.
1: -15   So the change in elevation per  min. is 15

So, the 10 min section of the walk the change of elevation was greater.      Hope that helps! if you need me to explain something just ask!
