Answer: There is convincing evidence at the the significance level that the DMV's claim is incorrect.
Step-by-step explanation:
Since we have given that
Hypothesis:
Probability of teens pass their drivers test on the first attempt = 60% = 0.60
Number of teens = 125
Number of them passed the tests on their first try = 86
So, the value of test statistic would be
At α = 0.05% level of significance, critical value = 1.645
Since 1.645 < 2.01
So, we will reject the null hypothesis.
Hence, there is convincing evidence at the the significance level that the DMV's claim is incorrect.
The correct answer is 5
Solve for x by simplifying both sides of the equation, then isolating the variable.
X=5
It says that the value of a box above two boxes is found by adding the expressions in the two boxes. I filled in the boxes. The top box is 13x + 30, or option B.
Answer:
Step-by-step explanation:
1 ring has a radius of 3 feet
1 ring has a circumfrence of 2*pi*r = 2 * 3.14 * 5 = 10*Pi
5 rings would have a length of 50 * pi length = 50*3.14 = 157 feet
That's a lot of Brillo pads.
Answer:
112x-420
Step-by-step explanation:
(5x + 9) (8x - 30)
distribute 5x into (8x-30)
then same with 9 into (8x-30)
then combine like terms and u will get da answer
hope this helps with da pic dat i attach
