Answer:
A. 7√3 in
Step-by-step explanation:
We first have to draw out the altitude on the triangle. When we do so, we should see that we will get 2 congruent 30-60-90 triangles. From there, our <em>h</em> height is <em>x</em> and we use tan∅ to solve:
tan60° = x/7
x = 7tan60°
x = 7√3
10/9 = 1.01 and you know 1/2 = 0.5 so 1.1 is closest to 1 because there is just 0.1 different between them :))

Step-by-step explanation:
When adults with smartphones are randomly selected, 61% use them in meetings or classes, then
- the probability of using the smartphone is
- the probability of not using the smartphone is

If 8 adult smartphone users are randomly selected, the probability that exactly 3 of them use their smartphones in meetings or classes can be calculated using binomial distribution as

Note that

then the probabilty is
