Answer:
Option A - The number of visitors is multiplied by (1+r) each year
Step-by-step explanation:
Given : The number of visitors to an art museum increases each year. The function 
represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.
To find : Select the correct statement?
Solution :
We have given an exponential function,
The function represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.
As In year 0,
The initial visitors is 
In year 1,
In year 2,
So, According to this the number of visors is multiplied by (1+r) each year.
Therefore, Option A is correct.
solution:
You have only two qualitatively different outcomes possible. Count
the number of ways to get each of the two.
There are just two possible outcomes here: the two missing socks
make a pair (the best case) and the two missing stocks do not make a
pair (the worst case). The total number of different outcomes (the ways
to choose the missing socks) is 10 C 2 = 45.
The number of best-case ones is 5; hence its probability is 5 /45 = 1/9
The number of worst-case ones is 45 − 5 = 40; hence its probability is 40/45 = 8/9.
On average, you should expect 4 • 1/ 9 + 3 • 8 /9 = 28/ 9 = 3 1/ 9 matching pairs.
2 1/8 - 1 2/7 = ?
8*2+1/8 - 7*1+2/7 =
17/8 + 9/7 =
8,7 | 2
4,7 | 2
2,7 | 2
1, 7 | 7
1, 1 | 1_______ 2*2*2*7 = 56
17/8 + 9/7 =
56÷8*17/56 + 56÷7*9/56 =
7*17/56 + 8*9/56 =
119/56 + 72/56 = 191/56
Answer:
191/56
Answer:
p= -1
Step-by-step explanation:
5p-17p-9p+(-14)=7
5-17-9= -21p
-21p-14=7 add 14 to both sides
-21p=21 divide both sides by -21
p= -1
check 5(-1)-17(-1)-9(-1)+ (-14)=7
-5+17+9-14=7
Answer: 4(2x - 5)
Step-by-step explanation:
factors of 8 : (2, 2), 2
20 : (2, 2), 5
Therefore the GCF is 2*2 = 4
8x/4 = 2x and -20/4 = -5
4(2x - 5) = 8x - 20
