150
Step-by-step explanation:
45/300 is the probability of blue because out of 300, 45 were blue than times by 1000
Answer:
We conclude that the mean weight of cereal in its 18-ounce boxes is less than 18 ounces.
Step-by-step explanation:
We are given that a researcher performs a hypothesis test to test the claim that for a particular manufacturer, the mean weight of cereal in its 18-ounce boxes is less than 18 ounces.
Let = <em><u>mean weight of cereal in its 18-ounce boxes</u></em>.
So, Null Hypothesis, : = 18 {mean that the mean weight of cereal in its 18-ounce boxes is equal to 18 ounces}
Alternate Hypothesis, : < 18 {mean that the mean weight of cereal in its 18-ounce boxes is less than 18 ounces}
Also, it is given that the P-value is 0.01 and the level of significance is 0.05.
<u>The decision rule based on the P-value is given by;</u>
- If the P-value of our test statistics is less than the level of significance, then we have <em>sufficient evidence to reject our null hypothesis </em>as our test statistics will fall in the rejection region.
- If the P-value of our test statistics is more than the level of significance, then we have <em>insufficient evidence to reject our null hypothesis</em> as our test statistics will not fall in the rejection region.
Here, clearly our P-value is less than the level of significance as 0.01 < 0.05, so we have <em>sufficient evidence to reject our null hypothesis </em>as our test statistics will fall in the rejection region.
Therefore, we conclude that the mean weight of cereal in its 18-ounce boxes is less than 18 ounces.
B - Citizens participate in the government of their country
If you use desmos it helps also the -2 you start out with on point (0,-2) then go down three and right one and continue
Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
