Answer:
The population in 2015 will be 165 million.
Step-by-step explanation:
The exponential growth formula is given by:
[tex] f(t) = a(1 + r)^{\Delta t} [/tex]
Where:
a: is the initial population
r: is the rate of increase
Δt: is the time
With the initial information we can find the rate:
[tex] 151 = 145(1 + r)^{1998-1990} [/tex]
Using logarithm:
[tex] ln(151) = ln(145) + 8[ln(1 + r)] [/tex]
[tex] ln(1 + r) = \frac{ln(151) - ln(145)}{8} [/tex]
[tex] ln(1 + r) = 5.0683 \cdot 10^{-3} [/tex]
Using exponential:
[tex] e^{ln(1 + r)} = e^{5.0683 \cdot 10^{-3}} [/tex]
[tex] r = 5.081 \cdot 10^{-3} [/tex]
Now, we can find the estimated population in 2015:
[tex] f(t) = 151(1 + 5.081 \cdot 10^{-3})^{2015-1998} [/tex]
[tex] f(t) = 165 [/tex]
Therefore, the population in 2015 will be 165 million.

Simplify the equation to find the value of a.
Subtract 4a from both sides:

Add 15 to both sides:
[tex] - 3a = 12[/tex]
Divide each side by -3:

What is the mean value of Keisha’s data?
A. 0.75
B. 1
C. 1.3¯
D. 2
Answer:sorry its c
Step-by-step explanation:
The mean value of Keisha’s data is 1.333333.
What is Mean?The mean is the average of a set of variables in mathematics and statistics. There are several methods for computing the mean, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations),
We have the data,
0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2.
So, the mean value of data is
= (0 +1 + 0 + 2 + 2 + 1 + 3 + 0 + 4 + 0 + 1 + 2)/12
= 16/12
= 4/3
= 1.33333

I THINK THE RIGHT ANSWER IS RHS THEOREM.A customer pay 72$ for 18 sandwiches. If each sandwich cost the same amount , what is the cost per sandwich, in dollars?
Answer:
Each sandwich costs 4$.
Step-by-step explanation:
To find the answer we will divide 72$ by 18 and we get 4$.
The number of sandwiches and the total price of sandwiches are directly proportional.
Cost of 18 sandwiches = $72
Cost of 1 sandwich = $72/18
= $4
Hence the cost of 1 sandwich is $4.

Step-by-step explanation:

~Set up an equation and solve for x :
→ [tex] \large{ \tt{10x + 45 \degree = 75 \degree + 70 \degree}}[/tex] [ Exterior angle is always equal to the sum of two non-adjacent interior angles ]
Add the numbers : 75° & 70°
→ [tex] \large{ \tt{10x + 45 \degree = 145 \degree}}[/tex]
Since we want to get rid of the constant in the left hand side , subtract 45 from both sides :
→ [tex] \large{ \tt{10x + 45 \degree - 45 \degree= 145 \degree - 45 \degree}}[/tex]
→ [tex] \large{ \tt{10x \: \cancel{ + 45 \degree} \: \cancel{ - 45 \degree} = 100 \degree}}[/tex]
