Answer:
Option B) Do not reject null hypothesis, there is not enough evidence to support the claim that the proportion of homes in Oregon heated by natural gas is different from the 48% that the US Department of Energy reported.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 333
p = 48% = 0.48
Alpha, α = 0.01
Number of women belonging to union , x = 149
First, we design the null and the alternate hypothesis
This is a two-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.273079
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to support the claim that proportion of homes in Oregon that were heated by natural gas is different from what was reported.
B. Do not reject null hypothesis, there is not enough evidence to support the claim that the proportion of homes in Oregon heated by natural gas is different from the 48% that the US Department of Energy reported.
Answer:
1. Because a right angle is 90 degrees, the answer to this is 90 - 65 = 25.
2. This question is similar to the last one, but this time the angle is 180 degrees total, so the answer is 180 - 55 = 125.
3. I'm fairly certain the lines here indicate that all three angles are the same. If all three angles make 180 degrees, the answer would be 180 / 3 = 60.
4. This is the same as in question 2. 180 - 135 = 45.
5. Again, because all three angles need to make up 180 degrees, we can just simply do 180 - (65 + 45) = 70.
6. With a quadrilateral, the angles add up to 360 degrees. We can do the same thing as in question 5 here. 360 - (70 + 95 + 55) = 140.
7. I don't remember exactly how to solve this but 55 degrees is correct because 55 + 55 + 70 = 180 which is the only possible value.
I haven't done this kind of stuff in a looooong time so I hope this suffices! :)
He will be able to eat 16 serving from the box that has 12 cups of cereal in it
Step-by-step explanation:
Charlie likes to eat 3/4 cup of cereal each morning for breakfast
We need to find how many servings he will be able to eat from a box
that has 12 cups of cereal in it
To solve the problem
- Divide the number of cubs in the box by the quantity he like to eat
- If the divisor in the division problem is a fraction we change the division to multiplication and reciprocal the divisor
∵ There are 12 cups in the box
∵ Charlie likes to eat 
cup
- Divide the number of the cups in the box by
∴ The number of serving = 12 ÷
Change the division sign to multiplication sign and reciprocal
∵ The reciprocal of = 
∴ The number of serving = 12 ×
∴ The number of serving = 
∴ The number of serving = 16
He will be able to eat 16 serving from the box that has 12 cups of cereal in it

Answer:
-2
Step-by-step explanation:
4 × -0.5 = -2
Answer:
sum of angles at a point is equal to 360
so, 360= 163+ x°+ y°+z°
y°=360-163 -x° - z°
y°=197- x° -z°
