Margot is looking at some information for the obstacle course she is interested in completing the x-coordinate is the number of the obstacle, while the y-coordinate

is the average time to complete the obstacle, measured in minutes

(1.6 25), (2.6875), (3, 7.5625), (4,8,31875)

margot use an explicit formula to find the average time she will need for the 8th obstacle.

(8) 11(6.25): (8) 409782

(8) = 6.25(1.1) (8) = 12.179

(8) = 11(625) (8) = 2561137

(8) = 6.25(1.1) (8) 13.397

the answer is 6.25(1.1)^8 = 13.397

Step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
