Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13
The answer would be 361/4 added to each side of the formula
Answer:
Step-by-step explanation:
The function s(x)=0.9(.82)^x models the number of subscription in tens of thousands where x represents the number of years since the trend has been observed.
s(x) represents the number of subscriptions to the Dorchester Daily in a given year.
0.9 in ten thousands represents the initial number of subscriptions to the Dorchester Daily in a given year.
0.82 represents the rate at which the number of number of subscriptions to the Dorchester Daily is declining. The rate in percentage is 100 - 82 = 12% each year.
x represents the number of years since the trend has been observed.
Answer:
G = -4x - 4
x = -1
Step-by-step explanation:
step 1: flip your equation and turn G into zero
ex: -4x - 4 = 0
step 2: add 4 to both sides
ex: -4x - 4 + 4 = 0 + 4 (-4x = 4)
step 3: divide both sides by -4
ex: -4x/-4 = 4/-4 (x = -1)
step 4: plug -1 into x then solve to check your answer
ex: -4(-1) - 4 = 0
4 - 4 = 0
0 = 0 (when this says 0 = 0 then that means your answer is always true)
