Answer:
(a) The probability that a randomly selected alumnus would say their experience surpassed expectations is 0.05.
(b) The probability that a randomly selected alumnus would say their experience met or surpassed expectations is 0.67.
Step-by-step explanation:
Let's denote the events as follows:
<em>A</em> = Fell short of expectations
<em>B</em> = Met expectations
<em>C</em> = Surpassed expectations
<em>N</em> = no response
<u>Given:</u>
P (N) = 0.04
P (A) = 0.26
P (B) = 0.65
(a)
Compute the probability that a randomly selected alumnus would say their experience surpassed expectations as follows:
![P(C) = 1 - [P(A) + P(B) + P(N)]\\= 1 - [0.26 + 0.65 + 0.04]\\= 1 - 0.95\\= 0.05](https://tex.z-dn.net/?f=P%28C%29%20%3D%201%20-%20%5BP%28A%29%20%2B%20P%28B%29%20%2B%20P%28N%29%5D%5C%5C%3D%201%20-%20%5B0.26%20%2B%200.65%20%2B%200.04%5D%5C%5C%3D%201%20-%200.95%5C%5C%3D%200.05)
Thus, the probability that a randomly selected alumnus would say their experience surpassed expectations is 0.05.
(b)
The response of all individuals are independent.
Compute the probability that a randomly selected alumnus would say their experience met or surpassed expectations as follows:

Thus, the probability that a randomly selected alumnus would say their experience met or surpassed expectations is 0.67.
Answer:
wait a minute i gonna comment the answer look there ok :)
Answer:
x = -1
y = 5
Step-by-step explanation:
x+y=4
3x+7y=32
<em><u>To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.</u></em>
x+y=4,3x+7y=32
<em><u>Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.</u></em>
x+y=4
<em><u>Subtract y from both sides of the equation</u></em>.
x=−y+4
<em><u>Substitute −y+4 for x in the other equation, 3x+7y=32.</u></em>
3(−y+4)+7y=32
<em><u>Multiply 3 times −y+4.</u></em>
−3y+12+7y=32
<em><u>Add −3y to 7y.</u></em>
4y+12=32
<em><u>Subtract 12 from both sides of the equation</u></em>.
4y=20
<em><u>Divide both sides by 4</u></em>.
y=5
<em><u>Substitute 5 for y in x=−y+4. Because the resulting equation contains only one variable, you can solve for x directly.</u></em>
x=−5+4
<em><u>Add 4 to −5.</u></em>
x=−1
<span>its false I hope I helped</span>
It can consist of translations (slides), reflections (flips), and rotations (turns).
I would say a reflection, then slide right, then slide down.
