The upcoming championship high school football game is a big deal in your little town. The problem is, it is being played in the next biggest town, which is two hours away! To get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. You determine that if more than three students share a ride, on average, you will create the app.
You conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. The following data are collected:
6 5 5 5 3 2 3 6 2 2
5 4 3 3 4 2 5 3 4 5
You and your partner will construct a 90% confidence interval and 95% confidence interval for the mean number of students who share a ride to school, then you will compare and interpret the results.
Part A: Decide which partner will construct each confidence interval, and then state the parameter and check the conditions.
Part B: Construct the confidence interval. Be sure to show all your work, including the degrees of freedom, critical value, sample statistics, and an explanation of your process.
Part C: Interpret the meaning of the confidence interval, and describe the difference in the width of the interval and the margin of error.
Part D: Use your findings to explain whether you should develop the ride-share app for the football game.

Work out the size of the angle marked x.
x
145
Answer:
x = 125°
Step-by-step explanation:
The sum of the angles around a point = 360° , then
90 + 145 + x = 360°
235° + x = 360° ( subtract 235° from both sides )
x = 125°

100 POINTS!!! ONLY 1 QUESTION! WILL GIVE BRAINLIEST. Please EXPLAIN how you got the answer
Answer:
A
Step-by-step explanation:
its hard to explain but pretty much if you didn't know the ^x+1 is the x intercept except when its graphed its no marked at (1,0) its mark ate (-1,0) because it always takes the inverse
if you go over to the right 3 then your adding 3 to the x intercept or subtracting 3 from ^x+1 so it would be ^x-2
the y intercept part is easy all you have to do is subtract 2 from the y intercept so it would be +2

reduce:
add 2x to each side:
9x-6 = 12
add 6 to each side:
9x = 18
divide both sides by 9:
x = 2

Mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.
What is mean?Mean is the sum of numbers divided by the numbers. It is also known as average.
How to calculate values?Fow calculating mean we have to find sum of numbers which is calculated in figure as 1553.
Mean=1553/25=62.12
Mode is basically the number having higher frequency which is 53.
Median is[ (n+1/2)th term,(n/2)th term]/2
=(60+60)/2
= 60.
Range is basically the difference of smallest number and largest number divided by 2=82-49=32
Q3=3(N+1)/2
=3(25+1)/2
=18.5th term which is 69.
Hence mean of the data is 62.12, median is 60, mode is 53, range is 32, Q3 is 69.

Factoring quadratic trinomials.
List down all the factors of (13).
List down the sum of (40).
Identify which two factors add up to 13.
x^2 + 13x + 40
Answer:
The correct solution is "x = -5 and x = -8".
Step-by-step explanation:
The given equation is:
⇒ [tex]x^2+13x+40=0[/tex]
On factorizing the above equation, we get
⇒ [tex]x^2+5x+8x+40=0[/tex]
On taking "x" common, we get
⇒ [tex]x(x+5)+8(x+5)=0[/tex]
⇒ [tex](x+5)(x+8)=0[/tex]
Now,
⇒ [tex]x+5=0[/tex]
On subtracting "5" from both sides, we get
⇒ [tex]x+5-5=0-5[/tex]
⇒ [tex]x=-5[/tex]
Or,
⇒ [tex]x+8=0[/tex]
On subtracting "8" from both sides, we get
⇒ [tex]x+8-8=0-8[/tex]
⇒ [tex]x=-8[/tex]

find the x and y intercepts
find vertical and horizontal asymptotes
determine the holes
Step-by-step explanation:
First, I decided to determine the vertical asymptote! You can determine the vertical asymptote by taking the denominator and setting it equal to zero.
−4x+4=0
−4x=−4
x=1
There's a vertical asymptote at x=1.
Now for the horizontal asymptote! The horizontal asymptote is determined by looking at the leading coefficients in the numerator and denominator. Here's a helpful visual.
content://com.cryptotab.android.FileProvider/images/screenshot/16159519510813476709092178134526.jp
In our case, the leading coefficient in the numerator (x2) is larger than the leading coefficient in the denominator (−4x). This means there is no horizontal asymptote!
In some cases, a slant asymptote may be present in a graph. These are sometimes present in graphs that have a stronger leading coefficient in the numerator than the denominator. To determine the slant asymptote, we need to divide the numerator by the denominator.
content://com.cryptotab.android.FileProvider/images/screenshot/16159520052041557972364765603410
The slant asymptote is y=−x4−1
Holes are determined by finding numbers that when plugged into x, return undefined. On a graphing calculator these values will give us an error. Luckily for us, there are no holes, so we can move on.
X-intercepts are values that make the numerator equal zero. We can find these by setting the numerator equal to zero and solving.
x2+3x=0
x(x+3)=0
x+3=0
x=−3
Another number that makes the numerator equal zero is, well, zero!
x2+3x=0
(0)2+3(0)=0
0=0
So we know our x-intercepts are 0 and -3.
To find the y-intercepts, set x equal to zero and solve the equation!
y=x2+3x−4x+4
y=(0)2+3(0)−4(0)+4
y=04
y=0
So we have a y-intercept at y=0!
A rectangle or prism measures 3 1/2 cm long to 2 1/2 cm wide and 1 1/2 cm high how many tubes with side length of 1/2 cm I needed to fill the prism
Answer:
4/2
Step-by-step explanation:
At which value(s) of x does the graph of the function f(x) have a vertical asymptote? Check all that apply
F(x)=x-5/3x(x+1)
The vertical asymptotes are x= 0 and x = -1 option (D) and option (F) are correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
F(x) = (x-5)/3x(x+ 1)
To find the vertical asymptotes:
3x = 0
or
x = 0
x + 1 = 0
or
x = -1
Thus, the vertical asymptotes are x= 0 and x = -1 option (D) and option (F) are correct.

You spent $175 on a pair of shoes and three shirts. Each shirt cost the same amount. The shoes cost four times the amount of one shirt.
A) Graph the system of equations.
B) What was the price of the shoes and each shirt?
Please answer and take seriously will give brainliest
Step-by-step explanation:
1. making the equation:
shoes = x
shirts = y
175 = x + 3y
x = 4y
2. graph it (I'm using desmos)
the green line is for 175 = x + 3y and the purple one is for x = 4y
3. find the price
x = 4y
175 = 4y + 3y
175 = 7y
y = 175/7 = $25
price of the shirt = $25
x = 4y = 4*25 = $100
price of a pair of shoes = $100

The equation of a line is written as y = mx + b, where m is the slope and b is the y intercept.
You are given the slope: 5
The y-intercept is the y value when x is 0, this is also the point given to you (0,4), so the y-intercept (b) is 4.
The equation is y = 5x +4
The equation of line is y = mx + b where m is slope.
In the given question slope is 5
So, we can substitute m with 5, and we get
y = 5x + b
The y-intercept is the y value when x is 0, this is also the point given to you (0,4), so the y-intercept (b) is 4
∴ the final equation will be
y = 5x + 4
What is the Slope of a Line?
The slope of a line, otherwise called the slope is characterized as the worth of the steepness or the heading of a line in a direction plane. Incline can be determined utilizing various techniques, given the condition of a line or the directions of focuses lying on the straight line.
In Mathematics, a slope of a line is the adjustment of y-coordinate as for the adjustment of x direction. The net change in y-coordinate is addressed by Δy and the net change in x-coordinate is addressed by Δx. Where "m" is the slant of a line. In this way, tan θ to be the slope of a line.
