Answer:

area equals to 1/2 a + b * height so I have divided 1/2 which I've taken to divide 4.4 + 3.2 which equals to 7.6 * 3 so 1/2 divide divide 7.6 is 3.8 .3.8 * 3 equals to 11.4 that's my answer 11.4 ft.

A bug was sitting on the tip of a wind turbine blade that was 24 inches long when it started to rotate. The bug held on for 5 ro

son4ous [18]

Answer:

240π

Step-by-step explanation:

Turbine blade that was 24 inches long is the radius of the circle the bug travels.

So the Circumference is = 2rπ = 2*24*π = 48π

The bug held on for 5 rotations. so the distance that the bug travels = 5*48π = 240π

We roll a pair dice 10,000 times. Estimate the probability that the number of times we get snake eyes (two ones) is between 280

Natali5045456 [20]

Answer:

0.3573 = 35.7%

Step-by-step explanation:

We roll a pair of dice 10,000 times so the mean and standard deviation is,

μ = 10000/36 =277.7 σ = $\sqrt{10000*\frac{35}{36^{2} } } =16.4$

$z_{1}$ = (280 - 277.7)/16.4 = .14

$z_{2}$ = (300 - 277.7)/16.4 = 1.35

Probablity (range)

0.3573

Z(low)=0.14 0.555766357

Z(upper)=1.36 0.91304644

At a gathering of 15 people, there are 10 people who all know each other and 5 people who know no one. People who do not know ea

melomori [17]

Answer:

Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.
