Answer:
B. Exponential.
Step-by-step explanation:
Each year you can find the estimated population for the following year by multiplying by 1 + 1.7% = 1.017.
The population estimate in x years time = 78,918 (1.017)^x.
Answer:
Step-by-step explanation:
Simplify ——————
3x - 1
Equation at the end of step 1 :
(6x - 1)
y - ———————— = 0
3x - 1
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using (3x-1) as the denominator :
y y • (3x - 1)
y = — = ————————————
1 (3x - 1)
Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times
Answer:
ok the formula is Width= P
/2﹣l
68/2-18=16
the width is 16
Step-by-step explanation:
Answer: 4/7
This is a fraction
---------------------------------------------------
The two points are (x1,y1) = (2,3) and (x2,y2) = (9,7)
Which breaks down to these four facts
x1=2
y1=3
x2=9
y2=7
Plug those values into the slope formula below and simplify
m = (y2 - y1)/(x2 - x1)
m = (7 - 3)/(9 - 2)
m = 4/7
The slope is 4/7
Side Note: slope = rise/run = 4/7 so rise = 4 and run = 7. Meaning that each time we go up 4, we also go to the right 7
