#6 the x-intercept is (-2,0) and y-intercept is (0,4)
And then
#7 so make x=0 for y intercept. So
y=3(0)+6
y=6
So the y-intercept is (0,6)
Then for x-intercept make y=0
So
3x-6=0
Solve for x.
3(x-2)=0
Divide both sides by 3
x-2=0
Add 2 to both sides
x=2
So
x-intercept is (2,0)
#8 make y=0 for x-intercept so you get
0+2=|x-4|
2=|x-4|
x-4=2 or x-4=-2
x=6 or x=2
So your x intercepts for that one are (6,0) and (2,0)
Lastly for y-intercept you make x=0 and solve for y
So you get
y+2=|0-4|
y+2=|-4|
y+2=4
y=6
So the y-intercept for that one is (0,6)

Choose 1 answer:
Answers
Using the quartiles of the data-set, it is found that there is one high outlier in the data-set.
What are the median and the quartiles of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.The first quartile is the median of the first half of the data-set, which is also the 25th percentile.The third quartile is the median of the second half of the data-set, which is also the 75th percentile.The interquartile range is the difference between the third quartile and the first quartile.The dot plot shows the frequency of each observation, hence the complete data-set is given by:
4, 7, 8, 8, 9, 9, 10, 10, 10, 10, 11, 12, 12, 13, 13, 14, 16, 18, 20.
The quartiles are found as follows:
The first half is composed by the first 9 elements, given by 4, 7, 8, 8, 9, 9, 10, 10, 10, hence Q1 = 9.The second half is composed by the last 9 elements, given by 11, 12, 12, 13, 13, 14, 16, 18, 20, hence Q3 = 13.The IQR is given by:
IQR = Q3 - Q1 = 13 - 9 = 4.
The high outliers are the values that are more than 1.5 IQR above Q3, hence the threshold is given by:
13 + 1.5 x 4 = 19.
There is only value greater than 19, which is of 20, hence there is one high outlier in the data-set.

3. 1/2 divided by 2/5
4.11/3 divided by 4/5
Answers
Answer:
#1 = -2
Step-by-step explanation:
First, we need to make -2 2/3 an improper fraction. An improper fraction is a fraction whose numerator is bigger than its denominator.
you first multiply the whole number (ignoring the negative sign for now) by the denominator:
2*3=6
then you add the numerator:
6+2=8
finally you put that number over the denominator and then put the negative sign back:
-8/3
Next, you can use keep change flip to solve the division
You keep the first fraction, change the division sign to a multiplication sign, and flip the numerator and the denominator of the second fraction:
-8/3 divided by 4/3 becomes -8/3 x 3/4
finally you multiply across as you would normally and simplify
-8/3 x 3/4= -24/12
-24/12 simplified is -2

(5x - 22) + (x + 28) = 180
5x - 22 + x + 28 = 180
6x + 6 = 180
6x = 180 - 6
6x = 174
x = 174/6
x = 29
<A = 5x - 22 = 5(29) - 22 = 123
∠A+ ∠B=180
put the values
5x-22+x+28=180

The time when the two total costs would be equal is 6 hours.
When would the total cost be equal?The equation that can be used to represent the total cost of renting a canoe is a linear function. A linear equation is an equation that has a single variable raised to the power of 1. A linear equation increases by a predetermined constant. An example of a linear equation is 2x + 2.
The form that the equation would be is:
Total cost = rental fee + (cost per hour x number of hours)

Find the center of mass of the wire that lies along the curve r and has density =4(1 sin4tcos4t)
Answers
The mass of the wire is found to be 40π√2 units.
How to find the mass?To calculate the mass of the wire which runs along the curve r ( t ) with the density function δ=5.
The general formula is,
Mass = [tex]\int_a^b \delta\left|r^{\prime}(t)\right| d t[/tex]
To find, we must differentiate this same given curve r ( t ) with respect to t to estimate |r'(t)|.
The given integration limits in this case are a = 0, b = 2π.
Now, as per the question;
The equation of the curve is given as;
r(t) = (4cost)i + (4sint)j + 4tk
Now, differentiate this same given curve r ( t ) with respect to t.
[tex]\begin{aligned}\left|r^{\prime}(t)\right| &=\sqrt{(-4 \sin t)^2+(4 \cos t)^2+4^2} \\&=\sqrt{16 \sin ^2 t+16 \cos ^2 t+16} \\&=\sqrt{16\left(\sin t^2+\cos ^2 t\right)+16}\end{aligned}[/tex]
Further simplifying;
[tex]\begin{aligned}&=\sqrt{16(1)+16} \\&=\sqrt{16+16} \\&=\sqrt{32} \\\left|r^{\prime}(t)\right| &=4 \sqrt{2}\end{aligned}[/tex]
Now, use integration to find the mass of the wire;
[tex]\begin{aligned}&=\int_a^b \delta\left|r^{\prime}(t)\right| d t \\&=\int_0^{2 \pi} 54 \sqrt{2} d t \\&=20 \sqrt{2} \int_0^{2 \pi} d t \\&=20 \sqrt{2}[t]_0^{2 \pi} \\&=20 \sqrt{2}[2 \pi-0] \\&=40 \pi \sqrt{2}\end{aligned}[/tex]

The ratio of 6th grade basketball players to 6th grade volleyball players is 5:2 if THERE ARE 30 BASKETBALL PLAYERS HOW MANY VOLLEYBALL AYERS ARE THERE
Answers
Answer: There are 12 volleyball players
Step-by-step explanation:
If the ratio of basket to volleyball players is 5:2 and there are 30 known basket ball players that means the ratio can be written as 30:x.
If 30 is 5 parts (5x) and volleyball players is 2 parts (2x) we need to figure out the value of 1 part (x)
This can be done by
5x=30
x=6
Now we know what 1 part is, we can now use that two figure out 2 parts
2x or 2(6)
2(6) = 12
So the ratio is 30:12. This can be confirmed by dividing both sides of the radio by 6 to get 5:2

• Both customers paid the same amount per hot wing.
How much does one hot wing cost at this restaurant in dollars and cents?
Record your answer in the boxes below. Be sure to use the correct place value.

Answers
Explanation:
We’ll solve this with a set of equations since the price per wing is fixed and they paid the sam amount at the restaurant. Let x represent the cost of 1 wing.
8x + 4.00 = 10x + 2.80
4.00 = 2x + 2.80
1.20 = 2x
0.60 = x
So, we have found that one wing cost $0.60.

An online store sells old video games and DVDs as a bundle. A bundle of two video games and three DVDs can be purchased for $90.00. A bundle of one video game and two DVDs can be purchased for $51.50. Find the cost of one video game and the cost of one DVD in the bundle.
Answers
Using system of equations, the cost of one video game is $25.5; the cost of one DVD is $13.
How to Apply System of Equations to Solve a Problem?Given the problem above, we would do the following:
Video games = vDVDs = dUsing the information given, we would form two equations for the system as shown below:
2v + 3d = 90 ---> equation 1
v + 2d = 51.5 ---> equation 2
Multiply equation 2 by 2 to get equation 3
2v + 4d = 103 ---> equation 3
Subtract equation 1 from equation 3
d = 13
The cost of one DVD = d = $13.00
Substitute d = 13 into equation 2
v + 2d = 51.5 ---> equation 2
v + 2(13) = 51.5
v + 26 = 51.5
v = 51.5 - 26
v = 25.5
The cost of one video game = v = $25.50.
Therefore, using system of equations, the cost of one video game is $25.5; the cost of one DVD is $13.
