Answer:

x = 7

Step-by-step explanation:

Parallel lines so their the same

11x - 2 = 75

add 2 to both sides

11x = 77

divide both signs with 11

x = 7

Answer:

The answer to the equation below is also 75 degrees. X equals 7

Step-by-step explanation:

Assuming that the lines are parallel, we can confirm that the two angles are corresponding because they are cut by a traversal (corresponding means that they occupy the same relative position). Knowing that the are corresponding use the equation 11x-2= 75 to find x. You are welcome and I hope you get the best grade possible :). Have a nice day!

You apply for a job and have to take a drug test. You are curious about the error rate for the test so you do some research. You

Ber [7]

Answer:

Test statistic Z = -1.0

|Z| = |-1.0| < 1.96 at 0.05 level of significance.

The null hypothesis is accepted

The company that produces the drug test claims that less than 14% of the test results are wrong

Step-by-step explanation:

Step(i):-

Given that the population proportion P = 14% =0.14

Given that the sample size 'n' = 382 tests

Given that find a study where 47 out of 382 test results using this test were wrong (either a false positive or a false negative).

Sample proportion

$p = \frac{x}{n} = \frac{47}{382} = 0.1230$

Null hypothesis: H₀ : P = 0.14

Alternative Hypothesis:H₁ : P≠ 0.14

Step(ii):-

Test statistic

$Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }$

$Z = \frac{0.1230-0.14}{\sqrt{\frac{0.14 X0.86}{382} } }$

Z = - 1.0

|Z| = |-1.0| < 1.96 at 0.05 level of significance.

Final answer:-

The null hypothesis is accepted

The company that produces the drug test claims that less than 14% of the test results are wrong
