19.6 is the answer because theee and seven eights times five and one sixteen is 19.6
That would make it 6 squared and 8 squared but the answer would be 48
Answer:
y=-1/2x-1/2
Step-by-step explanation:
For this, you need to use the point slope formula, (y-y1)=m(x-x1). The slope, m, would be -1/2 since the line we're looking for is perpendicular (meaning the slope is the negative reciprocal of the original slope). The x1 would be 3, and the y1 would be 1.
(y-y1)=m(x-x1)
(y-1)=-1/2(x-3)
y-1=-1/2x-3/2
y=-1/2x-1/2
The point estimate is 29.73% and the lower and upper limits are 26.63% and 32.83% respectively.
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
Point estimate = 22/74 = 0.2973 = 29.73%
Lower limit = point estimate - MOE = 29.73 - 3.1 = 26.63%
Upper limit = point estimate + MOE = 29.73 + 3.1 = 32.83%
Thus, the point estimate is 29.73% and the lower and upper limits are 26.63% and 32.83% respectively.
