Answer:
2091
Step-by-step explanation:
The correct answer is CI = (71.415%, 78.915%)
The correct option is (A)
<h3 /><h3>What is Confidence level?</h3>
A confidence interval is the mean of your estimate plus and minus the variation in that estimate.
Given:
x = 376
Sample = 500 students
CI= [(376/500-1.96 √((376/500)*(124/500)/500) , (376/500-1.96
√((376/500)*(124/500)/500)]
CI = (71.415%, 78.915%)
Hence, CI = (71.415%, 78.915%)

2x + 1 = 9
First step is to remove the integer (whole number)
Remove 1
2x = 8
Then divide by 2 to find x
x = 4
P = 58 inches
58 = 2 x height + 2 x width
58 = 2h + 2w
58 = 2 x 18 + 2w
58 = 36 + 2w
Get rid of the whole numbers
22 = 2w
Divide b 2 to find w
w = 11
Answer: Table B is a direct variation.
Step-by-step explanation:
Table A contains data that fits the expression y = x+3. This is not a direct variation. The ratio of x and y is not a constant. Table B matches the expression y = 3x. This is a direct variation. Table C can be expressed as y = x - 3. This is not a direct variation, for the same reason as Table A.
