Answer:
6% growth
Step-by-step explanation:
The equation =
A = 2300(1.06)⁷
What does 0.06 represent in the equation?
The formula for Exponential growth =
y = a (1 +r)^t
Where
y = Size after time t
a = Initial size
r = Growth rate in Percentage
t = Time t
Equating both Equations together
y = a (1 +r)^t = A = 2300(1.06)⁷
1 + r = 1.06
r = 1.06 - 1
r = 0.06
Converting to percent
r = 0.06 × 100
r = 6% growth rate
10.77(0.07) + 10.77 = $11.52
2.09(0.07) + 2.09 = $2.24
0.75(0.07) + 0.75 = $0.80
Add all of these up, and you get your total of A.) $14.56
Answer: 0.1359
Step-by-step explanation:
mean = $400
Standard deviation = $50
Since the wages is normally distributed , the first thing is to find the z - score.
z = 
finding the z - value for 300 and 350 , we have
z =
z = 
2 = -2
also
z = 
z = 
z = -1
The next thing is to check the calculated value on z - table.
From z - table :
P (z
-2 ) = 0.0228
P ( z
) = 0.1587
combining the two
P ( -2
z
-1 ) = 0.1587 - 0.0228
P ( -2
z
-1 ) = 0.1359
Therefore , the the probability that a worker
selected at random makes between
$300 and $350 = 0.1359
Answer:

Step-by-step explanation:
p(x) has degree 3
(x - 4) has degree 1
So p(x) can be rewritten as a polynomial of degree 2 multiplying (x-4)
So

To find a, b and c, we have to divide p(x) by x - 4.
So
Finding a:
Dividing the first term of p(x) by x - 4.

So a = 3.
Now multiplying 3x² by, x - 4, we have:

Subtracting p(x) from this:

Finding b:
Dividing the first term, after the subtraction, by x - 4.

So b = -8.
Multiplying -8x by x - 4, we have:

Then
Finding c:

So c = 5.
Just to verify if the remainder is 0.


Ok
Then:


Answer:
2
Step-by-step explanation:
it is the only number that occurs more than once
