In a random sample of 75 individuals, 52 people said they prefer coffee to tea. 99.7% of the population mean is between 84/80/74 % and 64/58/54%. (Choose the option closest to your answer.)

Answers

Answer 1

Answer: Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.

Answer 2

Answer:

The correct answers are

84 and 54

Barry needed 16 cubic feet of mulch to put under the playground equipment. Each bag of mulch covered 2.1 cubic feet. Barry planned on buying 16 bags of mulch. Is this a reasonable plan? A. No, it is not reasonable because each bag covers around 2 cubic feet. So in order to cover 16 cubic feet, he would need about 32 bags and he would end up with a little extra. B. No, it is not reasonable because each bag covers around 2 cubic feet. So in order to cover 16 cubic feet, he would only need about 8 bags and he would end up with a little extra. C. Yes, it is a reasonable answer because he needs 16 cubic feet of mulch so it is best to get 16 bags of mulch.

The measure of W is 134°, the measure of Y is 46°, and the measure of Z is 134°.What is the measure of X?
a 40°
b 46°
c 134°
d 90°

Answers

The angles in any quadrilateral must add up to 360 degrees.
A trapezoid is a quadrilateral, because it has four sides.

$W+X+Y+Z=360 \n \n (134)+X+(46)+(134)=360 \n \n 314+X=360 \n \n X=46$

Angle X is (b) 46 degrees.

B. 46 because the measure of all of the angles in a quadrilateral is 360. If you add 134+46+134 it equals 314, and 360-314 is 46.
