if the population of a city is 158,000 and is
decreasing by 8% every year, what will the
population be in 5 years?
Answers
Answer:
~ 104 135
Step-by-step explanation:
Decreasing by 8% each year means 92% is left each year
Formula
FV = PV ( i)^n FV = population in future PV = pop now
i = 92% in decimal form = .92 n = years = 5
FV = 158000(.92)^5 = 104135
A percentage is a way to describe a part of a whole. The population of the city after 5 years will be 104135.
What are Percentages?
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the population of a city is 158,000 and is decreasing by 8% every year. Therefore, the population of the city after 5 years will be,
Population after 5 years = 158,000(1-0.08)⁵
= 158,000 × 0.659
= 104134.8807 ≈ 104135
Hence, the population of the city after 5 years will be 104135.

on the high attempts the picture was cut off and the last one is 98 in the picture
Answers
Answer:
Below in bold.
Step-by-step explanation:
Mean = (98+92+90+78+83+88+95)/7
= 89.1 to nearest tenth.
Deviations:
98 - 89.1 = 8.9
92 - 89.1 = 2.9
90 - 89.1 = 0.9
78 - 89.1 = -11.1 = 11.1 (absolute value)
83 - 89.1 = 6.1
88-89.1 = 1.1
95 - 89.1 = 5.9
So the MAD
= (8.9+2.9+0.9+11.1+6.1+1.1+5.9)/7
= 36.9/7
= 5.27
= 5.3 to nearest tenth.

For funcitons f(x)=2x+3 and g(x)=-3x-2, please find (f∘g)(-1)
Answers
Answer:
[tex]\displaystyle (f\circ g)(-1) = 5[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]\displaystyle f(x) = 2x + 3\text{ and } g(x) = -3x - 2[/tex]
And we want to find:
[tex]\displaystyle (f\circ g)(-1)[/tex]
Recall that this is equivalent to:
[tex]\displaystyle (f\circ g)(-1) = f(g(-1))[/tex]
Hence, find g(-1):
[tex]\displaystyle \begin{aligned} g(x) & = -3x - 2\\ \\ g(-1) & = -3(-1) - 2\\ \\ & = (3) - 2 \\ \\ & = 1 \end{aligned}[/tex]
Substitute:
[tex]\displaystyle f(g(-1)) = f(1)[/tex]
Find f(1):
[tex]\displaystyle \begin{aligned} f(x) & = 2x+ 3 \\ \\ f(1) & = 2(1) + 3 \\ \\ & = 5\end{aligned}[/tex]
In conclusion:
[tex]\displaystyle (f\circ g)(-1) = 5[/tex]

A. 42
B. 36
C. 40
D. 38
Answers
Answer:
40 so C would be your answer.
The third quartile of the data set is 38.
What is Quartile?
Quartiles are statistical measures that divide a dataset into four equal parts, each representing 25% of the data. They are used to analyze the distribution and spread of data.
There are three quartiles: the first quartile (Q1), the second quartile (Q2), and the third quartile (Q3).
To find the third quartile of a data set, we need to arrange the data in ascending order and then locate the value that divides the upper 25% of the data from the lower 75%.
Arranging the data set in ascending order:
14, 18, 20, 21, 25, 32, 38, 42, 48
The data set has 9 values, so the third quartile will be the value at the
(9 0.75)th position
= 6.75th position.
Since we can't have a fractional position, we round up to the nearest whole number, which is 7.
The value at the 7th position is 38. Therefore, the third quartile of the data set is 38.

Answers
Step-by-step explanation:
There are 3 cubes in the solid's length, 2 in its width, and 3 in its height. Therefore, the number of cubes = length * width * height = 3*2*3 = 18
The volume of a small cube , for a length l, is l³. The length is (1/3)m, so the volume is (1/3)³ = 1/27 m³
volume of solid = number of cubes * area of each cube = 1/27 * 18 = 18/27 m³. This is because we have to figure out the volume of 18 cubes together, and we can just add each cube to the volume 18 times for our answer

Step-by-step explanation:
Knowing that:
3 vanilla cupcakes
3 other cupcakes
Total = 6
To Find:
What is the experimental probability that the next cupcake sold will be a vanilla cupcake?
Write your answer as a fraction or whole number.
P(vanilla cupcake)=
Solve:
Experimental probability is expressed as:
(Favorable outcomes) / (Total outcomes)
The favorable outcome in this situation is vanilla cupcakes. There were 3 vanilla cupcake sold, so this is the numerator of our fraction.
To find the total outcomes we add 3 + 3, which equals 6. This will be the denominator of our fraction.
The fraction used to express experimental probability will be: 3/6
We can further simplify this to 1/2.
Thus:
P(vanilla cupcake)= 1/2 or 3/6

Answer:
Ravi and Courtney
Step-by-step explanation:
Simplifying the equations
Penny
2x - y = -1y = 2x + 1
Ravi
2x + 3y = 33y = -2x + 3y = -2/3x + 3
Courtney
-4x - 6y = -66y = -4x + 6y = -2/3x + 3
Edwin
6x + 6y = 96y = -6x + 9y = -x + 9
Ravi and Courtney would have infinitely many solutions because they are the same equation.
Answer:
Ravi and Courtney have the same equation so they will have infinetely many solutions.
Step-by-step explanation:
Step 1: Solve each equation for y
Penny → [tex]2x - y = 1[/tex]
→ [tex]-y + 2x - 2x = 1 - 2x[/tex]
→ [tex](-y) * -1 = (1 - 2x) * -1[/tex]
→ [tex]y = 2x - 1[/tex]
Ravi → [tex]2x + 3y = 3[/tex]
→ [tex]3y + 2x - 2x = 3 - 2x[/tex]
→ [tex](3y)/3 = (3 - 2x)/3[/tex]
→ [tex]y = -2/3x + 1[/tex]
Courtney → [tex]-4x - 6y = -6[/tex]
→ [tex]-6y - 4x + 4x = -6 + 4x[/tex]
→ [tex](-6y)/-6 = (-6 + 4x)/-6[/tex]
→ [tex]y = -2/3x + 1[/tex]
Edwin → [tex]6x + 6y = 9[/tex]
→ [tex]6y + 6x - 6x = 9 - 6x[/tex]
→ [tex](6y)/6 = (9 - 6x)/6[/tex]
→ [tex]y = -x + 1.5[/tex]
Answer: Ravi and Courtney have the same equation so they will have infinetely many solutions.

Which statement is true of a rectangle that has an area of 4x2 39x – 10 square units and a width of (x 10) units? the rectangle is a square. the rectangle has a length of (2x – 5) units. the perimeter of the rectangle is (10x 18) units. the area of the rectangle can be represented by (4x2 20x – 2x – 10) square units.
Answers
The length and width of the rectangle are (4x - 1) and (x + 10) then the perimeter of the rectangle is 10x + 18. Then the correct option is C.
What is a factorization?
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The polynomial of the rectangle will be given below.
4x² + 39x – 10
The factor of the polynomial will be
(4x - 1)(x + 10)
Then the perimeter of the rectangle will be
Perimeter = 4x - 1 + 4x - 1 + x + 10 + x + 10
Perimeter = 10x + 18

Angles in ΔLMN
(6x + 3)° = 6(12) + 3 = 75°(4x - 10)° = 4(12) - 10 = 38°(5x + 7)° = 5(12) + 7 = 67°
Solving for y in ΔSTU
