5 it's not a factor of 2058
Sarahtime (min) {3 } 5 12 17
distance (meters) {75} 125 300 425
Eva time (min) {2} 7 10 20
distance (meters) {52} 182 260 520
Sarah:meters over min =75 over 3 = 25 over 1
25 meters per min
Eva :meters over min= 52 over 2 =26 over 1
26 meters per min
eva is the faster swimming because 26 meters per min is faster then 25 meters per min .
i hope this help
Answer:
120 degrees the sum of all angle is 720 degrees In the above
Answer:
number of ways = 120
Step-by-step explanation:
The number of ways five children can pose for a photograph line up in a row is given by the number of permutations of 5 elements in 5 different positions (positions in the line), then
number of ways = number of permutations of 5 elements = 5! = 5 * 4 * 3 * 2 * 1 = 120
Since the first children that occupies the line can be on any of the positions (5 positions) , but then the second one can choose any of the 4 remaining positions (since the first children had already occupied one) , the third can choose 3 ... and so on.
Answer: d) $369.31 to $380.69
Step-by-step explanation:
Given;
Mean price x= $375
Standard deviation r= $20
Number of retail stores n = 50
Confidence interval of 95%
Z*(95%) = 1.96
Confidence interval = x+/-Z*(r/√n)
= $375+/- 1.96(20/√50)
= $375+/- 5.69
Confidence interval = ($369.31 to $380.79)
