Answer:
Step-by-step explanation:
We are looking for the length of the hypotenuse of the 45° right triangle with side of 70.7 ft.
<u>We know the equation:</u>
- h = s√2, is the length of the hypotenuse and side s
<u>Substitute and calculate:</u>
- h = 70.7*√2 = 99.98 ≈ 100 ft
Correct choice is B
Answer:
Step-by-step explanation:
Answer C is correct: Angle T is 95°.
Because the two horiz. lines are parallel, the "vertical angle" of angle T is equal to the "corresponding angle" of 95°.
The answer is (7/1/4)✖️(7/1/4)✖️(7/1/4)

Answer:
(c) H0 should be rejected
Step-by-step explanation:
Null hypothesis (H0): population mean is equal to 5
Alternate hypothesis (Ha): population mean is greater than 5
Z = (sample mean - population mean) ÷ (sd/√n)
sample mean = 5.3, population mean = 5, sd = 1, n = 500
Z = (5.3 - 5) ÷ (1/√500) = 0.3 ÷ 0.045 = 6.67
Using the normal distribution table, for a one tailed test at 0.01 significance level, the critical value is 2.326
Conclusion:
Since 6.67 is greater than 2.326, reject the null hypothesis (H0)
Answer:
Because we know for a fact that the line has a correct answer. Plus, if you choose a point on the line then it will not give you the visual side of which is correct and which is wrong.
