Answer:
2,721,911.31
Step-by-step explanation:
The formula for Population growth rate is given as:
P(t) = Po(1 + r)^t
Where
Po = Initial population = 1,300000
P(t) = Population after t years
r = growth rate = 3%
t = time in years = 25
Hence,
P(25) = 1,300,000(1 + 0.03)^25
P(25) = 2,721,911.3086
P(25) Approximately = 2,721,911.31
The projected population of the county be in 25 years is 2,721,911.31
Find the x- and y-intercepts of the graph of the linear equation −6x+9y=−18.
Answer: it should be no solution.
Step-by-step explanation:
The graph of the linear equation −6x+9y=−18 , x = -3 and Y = -2.
What is linear equation?Linear equations are equations of the 1st degree. This is a straight line equation. The solutions of linear equations form the values that, when substituted into the unknown values, make the equation true. There is only one solution for one variable. For example, the equation x 2 = 0 has only one solution x = -2. However, for a linear equation in two variables, the solutions are calculated as the cross coordinates of a point in the Euclidean plane.
Given;
−6x+9y=−18
when x=0
then, -6(0)+9y= -18
9y = -18
y = -18/9
y = -2
put y= 0
-6x+9(0)= -18
-6x = -18
x = -18/6
x = -3

The two-way frequency table below shows data on whether medicine was taken and cold length for
participants in a study conducted by The Cold Be Gone Company.
Complete the following two-way table of column relative frequencies.
(If necessary, round your answers to the nearest hundredth.)
PLEASE HELP
Answer: Cold length 7+days and medicine taken is 0.24, the box under is 0.76. Cold length 7+days and medicine not taken is 0.69 and the box under is 0.31. It should look like: 0.24 0.69
0.76. 0.31
Step-by-step explanation: the box is vertical, the total is on the bottom and not the side. This means that you would have to add 6 and 19 together to get 25. 6/25 is 0.24 and the box under would be the rest of the number to get to 1.00 (0.76) because the total is on the bottom. If the total was on the side then you would do 6+27=33, then 6/33 = 0.18 and the remaining amount needed to get to 1.00 is 0.82. Furthermore, if the table has the total at the bottom then, the numbers you add are on the bottom and top box. If the table has the total on the side then, the numbers you add are the boxes that are on the left and right. Remember to round to the nearest hundredth. Your welcome.
The two-way column relative frequency table is,
Medicine taken Medicine not taken
cold length (≥ 7 days) 0.24 0.69
cold length (< 7 days) 10.76 0.31
Total 1.00 1.00
What is two-way frequency table?"It is a way to display frequencies for two categorical variables." "One category is represented by rows and a second category is represented by columns."What is two-way relative frequency table?"It is a way to display relative frequencies (percentages or ratios), instead of just frequency counts."
For given example,
we have been given a two-way frequency table on whether medicine was taken and cold length.
We need to find the column relative frequency table.
First we find the total of each column.
Medicine taken Medicine not taken
cold length (≥ 7 days) 6 27
cold length (< 7 days) 19 12
Total 25 39
Now, divide each element of column by its respective total.
Medicine taken Medicine not taken
cold length (≥ 7 days) 6/25 27/39
cold length (< 7 days) 19/25 12/39
Total 25/25 39/39
Therefore, the two-way column relative frequency table would be,
Medicine taken Medicine not taken
cold length (≥ 7 days) 0.24 0.69
cold length (< 7 days) 10.76 0.31
Total 1.00 1.00

Simplify this expression: -2x + 3 – (5 – 6x). Can someone pls explain how to do this dont just give the awnser
Answer:
-2x + 3 – (5 – 6x) = 4x - 2
Step-by-step explanation:
The given expression is :
-2x + 3 – (5 – 6x)
We need to simplify the above expression. First opening the brackets.
-2x + 3 – (5 – 6x) = -2x + 3 – 5 + 6x
Taking like terms together,
= -2x+6x + 3 -5
= 4x - 2
So, the simplified expression is 4x - 2.

Answer:
f(x)= -2|x-3|-1
(Hi Jasmine! I just wanted to help you with this question but I might be wrong)
Step-by-step explanation:
f(x) = a|x-h|+k
f(x)= a|x-3|-1
-7 = a |0-3| -1
-7 = a |-3| -1 <-- add to -7
-6 = a |-3|
-6 = 3a
-6/3 = a
-2 = a

Teacher chooses to students in a class of 15 girls and 10 boys the students are randomly choosing what is the probability that the teacher chooses to girls
Answer:
7/20
Step-by-step explanation:
So first we know that there are a total od 25 students
15+10=25
And the probability of choosing the first girl is 15/25 or 3/5 simpler terms.
Now to be able to choose another girl in a row just multiply the then probability
So we started off with 25, if a girl was choosen, the population would b 24
and with 24, there is a missing girl so instead of 15 it is 14
now 14/24 or 7/12 simplified
multiply the two
7/12*3/5=21/60
Simplified
7/20

Write the equation in slope-intercept form of the line that passes through
(12,9) and is perpendicular to the graph of y = -3/4x + 1.
Answer:
We conclude that the equation in slope-intercept form of the line that passes through (12,9) and is perpendicular to the graph of y = -3/4x + 1 will be:
[tex]y=\frac{4}{3}x-7[/tex]Step-by-step explanation:
We know the slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the line
y = -3/4x + 1
comparing with the slope-intercept form of the line equation
The slope = m = -3/4
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -3/4
Thus, the slope of the new perpendicular line = – 1/(-3/4) = 4/3
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values of the slope = 4/3 and the point (12, 9)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-9=\frac{4}{3}\left(x-12\right)[/tex]
Add 9 to both sides
[tex]y-9+9=\frac{4}{3}\left(x-12\right)+9[/tex]
[tex]y=\frac{4}{3}x-16+9[/tex]
[tex]y=\frac{4}{3}x-7[/tex]
Therefore, we conclude that the equation in slope-intercept form of the line that passes through (12,9) and is perpendicular to the graph of y = -3/4x + 1 will be:

Rachel participated in a 12-kilometer walkathon to raise money for her favorite charity. If it took her 2.5 hours to complete it, what was the rate in kilometers per hour?
Step-by-step explanation:
here they gave 12 km are reached by 2.5 hours so we. should how much time they took for 1km
12/ 2.5 which is also 150min
12km which is also 12000
12000/150= 80m
it took 80m in 1min so
1hr = 60min
1hr x 80m
60x80
4800
convert it intlo km
4800/1000
4.8km
so it took 4.8 km for 1hour
The time to complete the race is 2.5 hours, then the rate will be equal to 4.8 kilometers per hour.
What are arithmetic operations?The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.
They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.
As per the given information in the question,
Total distance = 12 kilometers
Total time taken to complete 12 kilometers = 2.5 hours
Then, the rate in kilometers per hour will be,
= 12/2.5
= 4.8 kilometers per hour.

Your given two side lengths of 6 centimeters and 9 centimeters. Which measurement can you use for the length of the third side to construct a valid triangle
Answer:
3cm < L < 15cm
Step-by-step explanation:
Given :
Side lengths:
Side 1 = 6cm and side 2 = 9cm
In other to construct a valid triangle, the length of the third side must lie in between.
That is ;
Minimum length must be greater than :
(side 2 - side 1)
9cm - 6cm = 3cm
Maximum length must not exceed :
(side 1 + side 2)
9cm + 6cm = 15cm
Hence, for a valid length for the 3rd side, L:
L > 3cm and L < 15 cm
3cm < L < 15cm
