Answer: Try 21
Step-by-step explanation:
The confidence interval for the proportion of students attending a football game is [0.6592, 0.7044].
Confidence interval can be calculated by below formula

where the left part is the lower interval and right side is the higher interval.
Pcap = 750/1100
Pcap = 0.6818
Again to calculate
, as we know that the level of confidence is 90 percent so its value will be 1.645
now putting the values on the both side we can get ,
0.6818 - 1.645 x 0.014 < p < 0.6818 + 1.645 x 0.014
0.6818 - 0.023 < p < 0.6818 + 0.023
0.6588 < p < 0.7048
the nearest value is [0.6592, 0.7044]
Hence the confidence interval for the proportion of students attending a football game is [0.6592, 0.7044]

Xy=-36
x+y=-3
x= -36/y
-36/y + y = -3
-36 + y^2 = -3y
y^2 +3y -36 = 0
I think you have to use quadratic formula to find the 2 values of y and then plug in for x
Answer:
16 or 8
Step-by-step explanation:
I'm not sure if this are right
-4.8x3.2 , 4.32/-3 , -2 3/5 - (1 2/5), 2 1/4+(-1 2/5)
So basically if they’re numbered from left to right then it would be 1, 3, 4, 2.
Problem 1 has a solution of -15.36
Problem 2 has a solution of 0.85
Problem 3 has a solution of -1.44
Problem 4 has a solution of -1.2
In order -15.36 would be the least greatest, because it is the farthest from zero. Followed by -1.44, -1.2, and lastly 0.85.
