Answer: a) critical value = 0.0853, b) we reject the null hypothesis.
Step-by-step explanation:
Since we have given that
z = -1.37
And the hypothesis are given below:
Since α = 0.01
since critical value = 0.0853
As we can see that 0.853 < 0.25.
so, we reject the null hypothesis.
Hence, a) critical value = 0.0853, b) we reject the null hypothesis.
Answer:
The value of 2 in 2000 is 10 times greater than the value of 2 in 200
Step-by-step explanation:
from the value of 2 in 200 to reach 2000, it takes 10 times as much because we're moving only one place (which is the thousand's digit).
So the first question you just need to convert it to its simplest form. You would do 105 \ 20 and that turns into 4 5/20.
The second question is turning it into a improper fraction so instead of dividing it you would multiply the whole number with the denominator, then add the numerator. So 4 x 9 = 36.
36 + 8 = 44
Add back the denominator to 44 and you get
44/9
Answer:
a > - 9
Step-by-step explanation:
Given
a + 6 > 0 ( subtract 6 from both sides )
a > - 6
Multiply both sides by 3 to clear the fraction
2a > - 18 ( divide both sides by 2 )
a > - 9
The answer is C. $95.83. To get the answer, you need to
convert all units into yard first. Then, multiply all the given numbers having
a result of 2.0827 cubic yards. Lastly, multiply the result to the concrete
cost of $46. So the cost to pour a slab for a patio is $95.83.
