Answer:
<h2>
The manager's claim is likely to be true.</h2>
Step-by-step explanation:
We are given that the factory produces 42,000 computer monitors per day
And the claim is of this amount produces fewer than 660 are defective.
a random sample shows that of 240 monitors 2 are defective
to verify the factory managers claim we need to know how many 240s are there in 42000
=42000/240= 175
Since each 240 will give 2 defective monitors
175 will give= 175*2= 350
350 is less than 660 hence the managers claim is correct
Answer:
228 and 222
Step-by-step explanation:
Answer:
F = 
C + 32
Step-by-step explanation:
Given
C = 
(F - 32)
Multiply both sides by to clear the fraction
C = F - 32 ( add 32 to both sides )
C + 32 = F
Answer:
B
Step-by-step explanation:
Converting it to z, we can use the formula of z-score:
z-score = 
Where
x is the value we are checking for (here, x = 79)
is the mean, which is 85
is the standard deviation, which is 4 now
<em>Let's plug the information into the formula and solve for the answer:</em>
