a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?
Answers
The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.
So, the confidence interval is:
178.6 ± 45.2
To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:
(178.6 + (178.6 - 45.2)) / 2 = 311.6
Therefore, the estimated number of students per grade level in the state is 311.6

Write the equations of each line in slope-intercept form. (y=mx+b)
Answers
The slope-intercept form of the equation of a line is given by:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
To find the equation of a line in slope-intercept form, we need to determine the values of m and b.
Here are two examples:
The line passes through the points (2, 4) and (4, 8).
To find the slope, we use the formula:
m = (y2 - y1)/(x2 - x1)
where (x1, y1) = (2, 4) and (x2, y2) = (4, 8)
m = (8 - 4)/(4 - 2) = 2
To find the y-intercept, we can use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
where (x1, y1) is one of the points on the line, for example, (2, 4).
y - 4 = 2(x - 2)
y - 4 = 2x - 4
y = 2x + 0
Therefore, the equation of the line in slope-intercept form is y = 2x.
The line passes through the point (3, 7) and has a slope of -3.
We can use the point-slope form of the equation of a line to find the equation in slope-intercept form.
y - y1 = m(x - x1)
where (x1, y1) is the given point, (3, 7), and m is the slope, which is -3.
y - 7 = -3(x - 3)
y - 7 = -3x + 9
y = -3x + 16
Therefore, the equation of the line in slope-intercept form is y = -3x + 16
Answer:
The equation would be y = -2x + 19
Step-by-step explanation:
To find this, we can use the point and the slope in point-slope form. The we solve for y.
y - y1 = m(x - x1)
y - 7 = -2(x - 6)
y - 7 = -2x + 12
y = -2x + 19

Elsa and Anna are running a race. Elsa is running at a rate of 2 meters per second and Anna is running at a rate of 1.75 meters per second. If Anna is given a 10 meter head start, how many seconds would it take for Elsa to catch up? Use an equation or system of equations to solve.
Answers
Step-by-step explanation:
Since Elsa is running at 2 and Anna at 1.75, we can first subtract
2 - 1.75 = 0.25, meaning each second Else gains 0.25m
Now that Anna was given a 10m headstart, we can divide 10 by 0.25
10/0.25 = 40
Meaning it would take 40 seconds for Elsa to catch up

Answer:
15 sides
Step-by-step explanation:
As we know the full angles of a polygon is 360°
And
Each side has angle 24°
So,
n = 360/24
n = 15 sides
I hope my answer helps you.
The polygon has 5 sides.
Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.
=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

Answer: See in the explanation, screenshot attached
Step-by-step explanation:
SQUARE QRTS
Step 1: Label all of the coordinates
Step 2: Find the coordinates of the points
Q: (-2, 1)
R: (2, 1)
T: (-2, -2)
S: (2, -2)
Step 3: Know what it means to dilate
To dilate is to make a shape bigger or smaller. For example, when it says to dilate by a scale factor of 2, you multiply each coordinate by 2 to get coordinate pairs that are twice the original amount (in this case you make it bigger). However, if it says to dilate by a scale factor of a fraction, for example 1/2, you'd multiply the coordinates by 1/2 and hence make it smaller (1/2 its size).
Step 4: Dilate by a scale factor of 2--multiply by 2
*x stands for the x coordinate, and y stands for the y coordinate*
Q: -2, 1
x: -2x2= -4
y: 1x2= 2
[Dilated] Q: -4, 2
R: 2, 1
x :2x2= 4
y: 1x2= 2
[Dilated] R: 4, 2
T: -2, -2
x: -2x2= -4
y: -2x2=-4
[Dilated] T: -4, -4
S: 2, -2
x: 2x2= 4
y: -2x2= -4
[Dilated] S: 4, -4
Step 5: Plot the new pairs

SQUARE ABCD
Step 1: Label all the coordinates
Step 2: Find the coordinate pairs of the points
A: -3, 3
B: 3, 3
C: 3, -3
D: -3, -3
Step 3: Remember what it means to dilate
(See 1st explanation)
Step 4: Dilate by a scale factor of 1/3
**Since 1/3 is a fraction, we are making the square smaller, or making it ⅓ of its original size. You will see that the numbers of the coordinates get smaller once you dilate them.**
A: -3, 3
x: -3x1/3= -1
y: 3x1/3= 1
[Dilated] A: -1, 1
B: 3, 3
x: 3x1/3 = 1
y: 3x1/3= 1
[Dilated] B; 1, 1
C: 3, -3
x: 3x1/3= 1
y: -3x1/3= -1
[Dilated] C: 1, -1
D: -3, -3
x: -3x1/3= -1
y: -3x1/3= -1
[Dilated] D: -1, -1
Step 5: Plot the new pairs

149 cars are waiting to take a ferry across the channel. Each ferry can only hold 18 cars. How many cars will be on the last ferry?
Answers
Answer:
5 cars will be on the last ferry
Step-by-step explanation:
If you divide 149 by 8, you get 8.27.
Since each ferry can hold 18 cars, you multipy 18 by 8 which results in 144. Then you subtract 144 from 149 and you get 5 :)
5
work:
149 divided by 18 equals 8.3
8 time 18 equals 144
149 - 144 = 5
Graph y+9=−3x
Identify the x-intercept
Answers
Answer:
formula is y=mx+b
the b(y-intercept) is -3x and m(slope) is 9.
In the graph, you would start at -3x on the y-axis (since it's on the y-intercept)
put your dot on -3x and move up 9.
you should land on positive 7(on the y axis)
9 must be a fraction so it would be 9/1
so, move once to the right on positive 7.

The vertices of a triangle are A(2,5), B(1,2), and C(3,1). Find the coordinates of the image after a rotation 90° clockwise about the origin.
Answers
Answer:
The images are;
A’ (5,2) B’ (2,1) and C’ (1,3)
Step-by-step explanation:
Firstly, we want to reflect across the x-axis
When we reflect a point (x,y) over x-axis, we get (x,-y)
So;
A ( 2,5) becomes (2,-5)
B (1,2) becomes (1,-2)
C ( 3,1) becomes (3,-1)
Then we proceed to rotate 90 degrees counterclockwise about the origin
Here we have;
(x,y) becomes (-y,x)
(2,-5) becomes (5,2)
(1,-2) becomes (2,1)
(3,-1) becomes (1,3)
