Answer:
254.45 meters squared
Step-by-step explanation:
Well the radius is 9 and that squared is 81 then that times pi is 254.45.
Answer:
x= 19
Step-by-step explanation:
Is given that the <u>triangles are congruent</u> so the corresponding sides are congruent as well.
Also congruent sides are equal in measure so we use the given picture to write the equality.
2x -1 = 37, add 1 to both sides
2x = 38 , divide both sides by 2
x = 19
The third one and the fourth one

Answer:
The expected number of times is 4.
Step-by-step explanation:
Looking at the question, we see that this follows a geometric distribution because it is asking for the expected number of trials hat will bring about the FIRST SUCCESS. The probability of success is
Since it is a geometric distribution, we know that the expected value of a random variable X, E(X) that follows a geometric distribution is given as:
E(X) = 1/p where p is the probability of success.
Therefore, the expected number of times will be
E(X) = 1/(1/p) = 1/(1/4) = 4.
Hence, the expected number of times is 4.
Answer:
D. 150
Step-by-step explanation:
Take a look at the graph. The y axis shows the containers recycled. From 0, the graph counts by 25 (0, 25, 50, 75, 100, etc.) The spot right above 50 and underneath 100 should be 75. So from 75 (on the y axis) move to the right until you reach the intersection. Now look at where the line and slope intersects, it’s at 150. That would help you predict how many people would be there.
