Below are the jersey numbers of 11 players randomly selected from a football team. find the range, variance, and standard deviation for the given sample data. what do the results tell us? 83 45 80 53 46 24 79 34 55 10 44 rangeequals 73 (round to one decimal place as needed.) sample standard deviationequals 23.4 (round to one decimal place as needed.) sample varianceequals 547.2 (round to one decimal place as needed.) what do the results tell us? a. the sample standard deviation is too large in comparison to the range. b. jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless. c. jersey numbers on a football team do not vary as much as expected. d. jersey numbers on a football team vary much more than expected.

40 minutes

step-by-step explanation:

add the time and multiply by 2

b, 20 yards

step-by-step explanation:

a = (-2, 0)

b= (-4, 0)

c = (-5,2)

d = (-1,2)

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
