Answer:

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Step-by-step explanation:

we know that

The isosceles trapezoid has :

Two parallel sides not equal in length called its bases  (KL and NM)

Two non-parallel sides equal in length (LM and NK)

so

NK=\sqrt{5}\ units

The perimeter is equal to

P=KL+LM+NM+NK

substitute the values

P=2\sqrt{2}+\sqrt{5}+\sqrt{2}+\sqrt{5}

P=(3\sqrt{2}+2\sqrt{5})\ units

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

The elevation of Location 1 is 20 feet above sea level and the elevation of Location 2 is 50 feet below sea level.
bearhunter [10]

Answer:

C.

Step-by-step explanation:

Location 1 is 20 feet ABOVE the sea level while Location 2 is 50 feet BELOW the sea level.

Location 1 would be 20

Location 2 would be -50

And think of the greater than and lesser than symbol as a alligators mouth it would go towards the bigger number so, -50 < 20, Location 1 is higher, is the answer.

About 1/4 of all adults in the United States have type O+ blood. If three randomly selected adults donate blood, find the probab
valina [46]

Answer:

a) 0.0156

b) 0.4219

c) 0.1406

Step-by-step explanation:

We are given the following information:

We treat adult having type O+ blood as a success.

P(Adult have type O+ blood) = 0.25

Then the number of adults follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 3

a) All three are type O+

P(x =3)\\= \binom{3}{3}(0.25)^3(1-0.25)^0\\= 0.0156

b) None of them is type O+

P(x =0)\\= \binom{3}{0}(0.25)^0(1-0.25)^3\\= 0.4219

c) Two out of the three are type O

P(x =2)\\= \binom{3}{2}(0.25)^2(1-0.25)^1\\= 0.1406

A skateboarder descends on a ramp from 172 feet to 67 feet in 15 seconds. What is the average height change in height per second
Tamiku [17]
7 feet per second, 172 minus 67 means he dropped 105 feet then divide that by how many seconds it took to get 7 fps.
