22 = z + (-9) Switch the sides
z = 22 - (-9) Solve
z = 31 So, z = 31

</span>P (not
one B+) + P (no B+) = 1
P (not one B+) = 1 – P (no B+)
<span> = 1 – 0.681472 </span>
P (at least 1 B+) = 0.318528=31.85%
<span>(d)
</span>B. The event in part (a) is unusual because its
probability is less than or equal to 0.05.

Answer:
3
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 2 ] , then
h(b) = h(2) = 0 ← from table for x = 2
h(a) = h(1) = - 3 ← from table for x = 1 , then
average rate of change = 
= 
= 3
Answer:
Step-by-step explanation:
It's given that 
. Because the side 
corresponds with the side 
, their lengths will be equal. Therefore, we have:
Plugging 
, we have:
.
