Yes. 0.2782 is a rational number.
It's the ratio of 2782 to 10,000 .
Hint:
If you wrote the number down using digits,
then you wrote a rational number.
Every number that can be completely written
with digits is a rational number.
Answer:
The first option is correct
The answer is 250 cm³
We need to calculate V = Vr - Vp
V - the <span>volume of the space outside the pyramid but inside the prism
Vr - the volume of the rectangular prism.
</span>Vp - the volume of the pyramid<span>
Vr = w * l * h
w = l = 5 cm
h1 = 12 cm
Vr = 5 * 5 * 12 = 300 cm</span>³<span>
Vp = w * l * h / 3
w = l = 5 cm
h2 = h1/2 = 12/2 = 6 cm
Vp = 5 * 5 * 6 / 3 = 50 cm</span>³
V = Vr - Vp = 300 cm³ - 50 cm³ = 250 cm³
Based on the responses, the significance level, and the p-value, we can conclude that the response proportions are not the same for the countries.
<h3>What can be concluded about the response proportions for these countries?</h3>
The null hypothesis is that the response proportions are the same. The alternate hypothesis is that the response proportions are not the same.
The sample size is large enough for a Chi-Square test to be used because the expected counts are all greater than 5.
Running a Chi-Square analysis shows that the P-value to be 0.000.
The P-Value is less than the significance level of 0.01 so the null hypothesis is rejected. This means that the alternate hypothesis of the response proportions not being the same is true.
