Complete question:

A recent study examined several variables on collegiate football players, including the variable Years, which is number of years playing football, and the variable Percentile, which gives percentile on a cognitive reaction test. The regression line for predicting Percentile from Years is:

Percentile 102 - 3.34 Years.

(a) Predict the cognitive percentile for someone who has played football for 7 years and for someone who has played football for 16 years. Enter the exact answers. The cognitive percentile for someone who has played football for 7 years is The cognitive percentile for someone who has played football for 16 years is

i) Cognitive percentile for someone who has played football for 7 years is 76.62

ii) Cognitive percentile for someone who has played football for 7 years is 46.56

Step-by-step explanation:

Given the regression equation: 102 - 3.34 (years)

Required:

Predict the cognitive percentile for someone who has played football for 7 years and for someone who has played football for 16 years

a) Cognitive percentile for someone who has played football for 7 years:

102 - 3.34 (years)

= 102 - 3.34(Y)

Substitute 7 for Y

102 - 3.34(7)

= 102 - 23.38

= 76.62

Cognitive percentile for someone who has played football for 7 years is 76.62

b) Cognitive percentile for someone who has played football for 16 years:

102 - 3.34 (years)

= 102 - 3.34(Y)

Substitute 7 for Y

102 - 3.34(16)

= 102 - 53.44

= 46.56

Cognitive percentile for someone who has played football for 7 years is 46.56

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
