A student who slept for 5 hours could be expected to score around 68.5,
According to the given information:
The table is,
x y
4 62
6 75
6 88
8 79
10 97
Now create a scatterplot of the data.
Use the trend line equation to make a prediction for what test score you would expect if a student slept for 5 hours.
From the scatterplot,
The trend line equation is y = 4.3x + 52.4.
To find the predicted test score for x = 5, substitute x = 5 into the equation:
y = 4.3(5) + 52.4 y = 75.9
So you would expect a student who slept for 5 hours to have a test score around 75.9.

You and some friends buy tickets to a raffle at your school. You can each buy one ticket. In total 150 tickets were sold. The probability that on of your friends win the raffle is 1/30. How many friends of yours bought tickets
Answer:5
Step-by-step explanation:
Given
There are total of 150 ticket
If the probability to win a raffle is [tex]\frac{1}{30}[/tex]
[tex]Probability =\frac{\text{Favorable outvome }}{\text{Total outcome}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{\text{Total no of tickets}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{150}[/tex]
no of tickets bought[tex]=\frac{150}{30}=5[/tex]
and no of tickets bought=No of friends
Therefore there 5 persons who bought tickets

What is the answer? To this question
Answer:
D.
Step-by-step explanation:
Firstly, we must look at the absolute value symbol. This means that if d is positive, it must be a number greater than 3. If d is negative, the number must be less than -3 (for the absolute value to be greater than 3.)
This results in A and D being possible solutions. HOWEVER, we must look at the ">" symbol.
Notice how the symbol solely represents "Greater than", and not "Greater than OR equal to".
This means that the number line must have OPEN circles at -3 and 3. This will give you solution D.

What is the absolute deviation of Victoria’s quiz score from the mean?
A. 0 points
B. 2 points
C. −1 point
D. 1 point
Please give the right answer
Answer:
B. 2 points(Approximately)
Step-by-step explanation:
The mean absolute deviation (MAD) is defined as
[tex]MAD=\frac{\Sigma |x_{i}-\mu| }{N}[/tex]
Where [tex]\mu[/tex] is the means and [tex]N[/tex] is the total number of elements.
First, we need to find the mean:
[tex]\mu = \frac{\Sigma x_{i} }{N} =\frac{18+12+15+10+13+20+16+12+18+6}{10}= \frac{140}{10}\\ \mu=14[/tex]
Then, we calculate the difference between each value and the mean, from that difference, we are gonna use the absolute value.
18 - 14 = |4|
12 - 14 = |-2|
15 - 14 = |-1|
10 - 14 = |-4|
13 - 14 = |-1|
20 - 14 = |6|
16 - 14 = |2|
12 - 14 = |-2|
18 - 14 = |4|
6 - 14 = |-8|
Now, we sum all terms and divide them by the total number of elements, which are 14.
[tex]MAD=\frac{4+2+1+4+1+6+2+2+4+8}{14}= \frac{34}{14}\\ MAD \approx 2.4[/tex]
Therefore, the absolute deviation is about 2 points. The right answer is B.

What are the Tree Numbers
Answer:
679.
Step-by-step explanation:
There is either a 1, 4 or 7 in the number.
From the second guess, 189, 1 cannot be in the number , either 8 or 9 are in right place. Also 4 or 7 are in the number.
9 6 4: 9 may be in the number, also 4 or 6.
No 2,3 or 5.
2 8 6 this tells us there is no 8 , and 9 is the last digit.
As there is no 2 there must be a 6 in the number
So the number contains a 9 and a 6.
The third number is either a 4 or a 7, but from the 964 result it cannot be a 4 because 6 is included.
So it either 679 or 769.
But 964 had 6 in the wrong place so the number is 679.
I think the answer is 679 because you every numbers make sense except for 679.

A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.
Explain how to find the arc length exactly, and then approximate it to one decimal place.
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in

Step-by-step explanation:
Write an equation of the line that passes through (0,3) and (4,2).
Answer:
y= [tex]\frac{-1}{4}[/tex]x+3
Step-by-step explanation:
To write an equation for a line, we will first need to find the slope of the graph. This can be done by using the slope formula:
m= [tex]\frac{y_{2-y_{1}} }{x_{2}-x_{1}}[/tex]
Now, we can plug these points in this equation.
m= [tex]\frac{2-3}{4-0}[/tex] --> m= [tex]\frac{-1}{4}[/tex] .
Since we have derived the slope, we can simply use one of the points listed to solve for our other values by plugging them into the line formula:
y= mx+b
------------
2= [tex]\frac{-1}{4}[/tex](4)+b
2=-1+b
3= b
Therefore, the equation we get is:
y= -[tex]\frac{-1}{4}[/tex]x+3
