Answer:
21°, 84°, 75° are the angles
Step-by-step explanation:
Total angle in a triangle is 180.
x + 4x + (5x - 30) = 180
10x - 30 = 180
10x = 210
x = 21°
Angles are:
A: 21°
B: 4(21) = 84°
C: 5(21) - 30 = 75°
The answer to the question is B. The test statistic is not between the critical values, so we reject the null hypothesis. There is sufficient evidence to support a claim of correlation between percentage of vote and income level.
<h3>What is the scatter plot?</h3>
This is the plot that shows the relationship between two different variables along a straight line. All of the points that are known to have a relationship between these variables would fall under this line. Other parts that fall outside the line are regarded as the outliers in the plot.
In this particular question, the outlier is seen to be outside of the critical values so we have to conclude that the solution is B. We fail to reject the null hypothesis.

67 degrees bc a straight line is 180 degrees
So 180-90=90
90-23=67
Answer:
48.8
Step-by-step explanation: The equation for the area of a circle is π*r², since the base of a cylinder is a circle we take the equation of a circle and multiply the height of the cynlinder by using the equation π*r²*h to get the volume of a cylinder. In this case our factors are
π= 3.14
r²= 6.76
h=2.3
3.14*6.76*2.3=48.82072
rounded to the nearest tenth=48.8
