a survey of an urban university (population of 25,450) showed that 750 of 1,100 students sampled attended a home football game d
DiKsa [7]

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

Pcap - Z_{\alpha /2}\sqrt{\frac{Pcap(1 - Pcap)}{n} } < p < Pcap + Z_{\alpha /2}\sqrt{\frac{Pcap(1 - Pcap)}{n} }

where the left part is the lower interval and right side is the higher interval.

Pcap = 750/1100

Pcap = 0.6818

Again to calculate Z_{\alpha /2} , 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]

25 sqr + 7 sqr = c sqr
625 + 49 = c sqr
625 + 49 = 674

c = sqr root of 674
c = 25.96 (rounded to 2dp)

Help me please im so mad :(:
Len [333]

Answer:

R- (-10, -3)

S- (-10, -6)

Q- (-5, -3)

P- (-5, -6)

Step-by-step explanation:

Well, Q and P would be the exact same coordinates since that land directly on the reflection line.

Basically, on this graph/question you can count how far away the vertices is from the reflection line.

For example, Point R is 5 units away from the reflection line, therefore I need to count over 5 times to the left from the reflection line for point R. (Idk if that makes sense or not, ask questions if you are confused).
