Answer:
0.1091 or 10.91%
Step-by-step explanation:
We have been given that a particular telephone number is used to receive both voice calls and fax messages. suppose that 20% of the incoming calls involve fax messages and consider a sample of 20 calls. We are asked to find the probability that exactly 6 of the calls involve a fax message.
We will use Bernoulli's trials to solve our given problem.







Therefore, the probability that exactly 6 of the calls involve a fax message would be approximately 0.1091 or 10.91%.
Answer:
The missing base measure of the enlarged trapezoid is 4cm.
Step-by-step explanation:
Step 1:
2 / 3.25 = x / 6.5
Step 2:
Cross product
2 * 6.5 = 3.25 * x
Step 3:
Simplify
13 = 3.25x
Step 4:
Divide both sides by 3.25
13 / 3.25 = 3.25x / 3.25
4 = x
x = 4
The missing base measure of the enlarged trapezoid is 4cm.
Answer:
A)A reflection can be used to create DBE
B)The Angles are congruent, as the transformation was rigid, which preserves angle measure and side length.
C)All the angles are corresponding to the second figure as well as the sides. (name all the sides and angles that are corresponding)
Ex: ABC=DBE
Hope this helps!
P.S. Stay Safe!
-Andrew-OUT!
The vector AB is found by subtracting the coordinates of point B from the coordinates of point A => (8, 3, 4) - (5, 7, - 2)
(8, 3, 4) - (5, 7, - 2) = (3, - 4, 6)
=>
a) a 3 x 1 column =
| 3 |
| -4 |
| 6 |
b) xi + yj + zk
=> 3i - 4j + 6k
3/36 (8.333%) thats the probability
