She drove 9 miles over the speed limit.
94.50 + 2m = 112.50
Subtract 94.50 from both sides
2m = 18
Divide both sides by 2
m = 9
Answer:
(a) 0.85
(b) 0.7225
Step-by-step explanation:
(a) The point estimate for the proportion of all such components that are not defective is given by the number of non-defective units in the sample divided by the sample size:

The proportion is 0.85.
(b) Assuming that the sample is large enough to accurately provide a point estimate for the whole population, this can be treated as a binomial model with probability of success (non-defective part) p = 0.85. Since both components must be non-defective for the system to work, the probability of two successes in two trials is:

An estimate of 0.7225 for the proportion of all such systems that will function properly.
Answer:
(86 – h) + h = 86
Step-by-step explanation:
$70+$260= $330
34 lemonade + 52 hot dogs = 86 items = $330
With 34 lemonade + 52 hotdogs h= 52
(86 – h) + h = 86 = 86-52+52=86
Answer:
-5a -16
Step-by-step explanation:
-6 + 5a - 6a - 10 - 4a
=5a -6a -4a -10 -6
= -5a -16
