Answer:
60 students
Step-by-step explanation:
The confidence interval of a proportion is given by:

Where 'p' is the proportion of students who responded 'yes', 'z' is the z-score for a 95% confidence interval (which is known to be 1.960), and 'n' is the number of students in the sample.
If the confidence interval is from 0.584 to 0.816, then:

60 students were in the sample.
The total of two whole numbers one after another is 33. for example 10 + 11 (two consecutive integers) = 21
Answer:
6 feet
Step-by-step explanation:
Consider the right triangle formed by the wall, ladder and ground.
Let the distance the ladder is from the wall be d , then
Using Pythagoras' identity in the right triangle
The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then
d² + 8² = 10²
d² + 64 = 100 ( subtract 64 from both sides )
d² = 36 ( take the square root of both sides )
d =
= 6
That is the ladder is 6 feet away from the wall
Answer: A
Step-by-step explanation:
12 x 12 = 144
39 x 39 = 1521
1521 - 144 = 1377
root 1377 = 37.1
-2/3
first do y2-y1 over x1-x2
then it’ll be 2-4 over 5-2
coming out as -2/3
