There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.
So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.
And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.
80% pf 45 times = 0.8 x 45 = 36 times .
Simple....
What is equivalent to 7(x-3)?
Distributing....
7*x=7x
7*-3=-21
7x-21
Thus, your answer.
The function f(x) = (6/120) x + 40
= 0.05x + 40 where x is the excess mileage over 100
If we drive it for 300 miles x will be 300-100 = 200
so cost will be 0.05*200 + 40
= 10+40 = $50 answer
Answer: The parametric is being tested here is "p" (population proportion).
The hypothesis test is left-tailed.
Step-by-step explanation:
Given : The null and alternative hypotheses are
The parametric is being tested here is "p", where p stands for population proportion.
Also, the type of test depends on the alternative hypotheses.
Since the alternative hypotheses is left-tailed, so the hypothesis test is left-tailed.
