Calculating the right-tailed test:
Therefore, we reject the null hypothesis.
This example shows that more than a third of the families own pets in this town.
Answer:
x ≈ 7.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos22° = =
Multiply both sides by 8
8 × cos22° = x, thus
x ≈ 7.4 ( to the nearest tenth )
0.37 meters of netting
<h3>Further explanation</h3><u>Given:</u>
Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.
<u>Question:</u>
How much netting did she use per goal?
<u>The Process:</u>
We will solve the problem of conversion or in other words the ratio or proportion.
Option A: the conversion
Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.
Then for every 1 goal, she needs 0.37 meters of netting.
Because
Option B: the ratio (or proportion)
In the ratio, we process as follows:
Both are divided by 4.
Thus, she uses 0.37 meters of netting per goal.
Alternative problem
How much netting did she use for 8 goals?
meters of netting.
We cross out eight and four because they can be divided.
She uses 2.96 meters of netting to make 8 identical mini hockey goals.
