Answer:

Step-by-step explanation:
A line is perpendicular to another if its slope is the negative reciprocal of the other.
Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope
. The negative reciprocal of that is
, which is the slope of the third answer choice.
Answer:
d) ÷
Step-by-step explanation:
120 ÷ 3/11 = 440
Answer:
The proportions differ from those reported in the survey.
Step-by-step explanation:
The Chi-square goodness of fit test would be used to determine whether the proportions differ from those reported in the survey.
The hypothesis for the test can be defined as follows:
<em>H</em>₀: The proportions does not differ from those reported in the survey.
<em>Hₐ</em>: The proportions differ from those reported in the survey.
Assume that the significance level of the test is, α = 0.01.
The Chi-square test statistic is given by:

Consider the Excel sheet provided.
The Chi-square test statistic value is 191.32.
The <em>p</em>-value of the test is:

The <em>p</em>-value of the test is very small. The null hypothesis will be rejected at 1% level of significance.
Thus, concluding that the proportions differ from those reported in the survey.
Answer:
Split the number into the whole number component and fraction component.
5 8/25= 5+8/25.
For the denominator, recognize that
25×4=100.
Multiple =4.
Multiply the numerator and the denominator by the multiple 4.
8×4/ 25×4.
Simplify.
32/100=0.32
Combine the whole number component with the decimal.
5+0.32=5.32
