<span>z = -0.95 </span>
<span>z = (525-515)/100/ √90 </span>
<span>z = 0.95 </span>
<span>P(-0.95< z < 0.95) = 0.6578 </span>
<span>P(-0.95< z < 0.95) = 0.6578 </span>
<span>c. P(484 < x-bar < 504) </span>
<span>z = (484-494)/100/√100 </span>
<span>z = -1 is 0.1587 </span>
<span>z = (504-494)/100/√100 </span>
<span>z = 1 is 0.8413 </span>
<span>P(-1< z <1) = 0.6826</span>
Answer:
see explanation
Step-by-step explanation:
The parts of the graph where it is going 'up' are where it is increasing.
This is between x = - 4 to x = 0 and between x = 5 to infinity
Expressing in interval form the graph is increasing for
(- 4, 0 ) and (5, ∞ )
First, we have to find the difference between the x and y numbers in the table. By dividing the y by the x, the c is being multiplied by 15.
So the answer would be y=15x
