A researcher collected data on years spent in college and yearly income. He found that the longer someone is in college, the lower his/her income is. Which of the following is true based on this research? Select all that apply.
The line of best fit for this data would be increasing from left to right on the scatter plot.
The slope of the line of best fit for this data would be negative.
The -intercept for the line of best fit for this data would be zero.
The line of best fit for this data is horizontal because the variables are not related.
If you divided the data into two groups and found the average years of college and average yearly income from each of the two groups, you could find the estimated slope of the line of best fit by using the slope formula on those representative points.

D)32/40
Hope it helps you
Answer:
[tex]\frac{24}{40}[/tex]
Step-by-step explanation:
Sin = [tex]\frac{opposite}{hypotenuse}[/tex] (relative to the angle asked for)
The opposite of Angle Z is 24
The hypotenuse no matter what would always be 40; therefore,
Sin(Z) = [tex]\frac{24}{40}[/tex]

Which Which value of x makes this equation true? -3x+10=5x-8
value of x makes this equation true? -3x+10=5x-8
Answer:
9/4
Step-by-step explanation:
-3x+10=5x-8
or, -3x-5x = -8-10
or, -8x=-18
or, 8x=18 (i.e. - is cancelled)
or, x=18/8
i.e. x=9/4
Hence, the value of x is 9/4
Answer:
The value of x is 9/4
Step-by-step explanation:
-3x+ 10 = 5x - 8
Add 3x both side
-3x + 3x + 10 = 5x + 3x - 8
10 = 8x - 8
Now, Add 8 both side
10 + 8 = 8x - 8 + 8
18 = 8x
8x = 18
Now, Divide by 8 from both side
8x/8 = 18/8
x = 9/4
Thus, The value of x is 9/4
FOR VERIFICATION ONLY:-3x + 10 = 5x - 8
-3(9/4) + 10 = 5(9/4) - 8
-27/4 + 10 = 45/4 - 8
-27 + 4 × 10/4 = 45 - 8 × 4/4
-27 + 40/4 = 45 - 32/4
13/4 = 13/4
Hence, L.HS = R.H.S

What linear equation is represented by the table?
Please hurry!
Best answer gets Brainliest!!!!
A) Y= 2x
B) y= 4x
C) y= 4x -2
D) y= 2x - 2
Answer:
y = 4x - 2
Step-by-step explanation:
linear equation - y = mx + b
where m = slope and b = y intercept
The y intercept is the y value of the coordinate where x = 0
Looking at the table, we notice that when x = 0, y = -2
Which means that the y intercept ( b ) = -2
Slope = change in y over change in x
As y goes up 4 x goes up 1
Thus, slope ( m ) = 4
Now we plug in the identified slope and y intercept into " y = mx + b "
we get that the equation is y = 4x - 2

If 49 voters are randomly sampled from the large number of voters in this area, approximate the probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08. (Round your answer to four decimal places.)
Answer:
The probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08 is 0.7698
Step-by-step explanation:
Given
n = 64
p = 0.20
X/n -p < 0.06
x-np <0.06n
x-np <0.06 * 64
x-np <3.84
Z score
= (x-np)/sqrt (np(1-p))
= -3.84/ sqrt (64*0.20*0.80)

P (x/n-p<0.06) = P(-1.2<z<1.20) = 1-2*0.1151 = 0.7698

What is an inequality?In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol.
Given is an inequality, x-1 / x-3 < 0, we need to find the graph of it,
Let p = x-1 and q = x-3
Now,
The problem we want to solve is in the form p/q < 0
Since p/q is negative, there are two cases we have to address ;
Case 1) p is positive and q is negative, or,
Case 2) p is negative and q is positive
The signs of p and q are opposite one another.
Case 1) If p is positive, then
p > 0
x-1 > 0
x > 1
If q is negative, then
q < 0
x-3 < 0
x < 3
Combine x > 1 with x < 3 and we get 1 < x < 3.
Case 2) If p is negative, then
p < 0
x-1 < 0
x < 1
If q is positive, then,
q > 0
x-3 > 0
x > 3
We get a contradiction.
Both "p is negative" and "q is positive" must be true at the same time. But if p is negative, then x < 1 which contradicts x > 3 (which happens when q is positive)
Put simply: case 2 is not possible. There's no way to have p be negative at the same time q is positive. This because we're wanting x to both be smaller than 1 AND also be greater than 3 at the same time.
We must rule out case 2 and side with case 1 instead.
The conclusion of case 1 was that 1 < x < 3
The graph of this has open holes at 1 and 3 on the number line. The shading is between the open holes to represent all values between 1 and 3, excluding the endpoints.
Hence, the graph is C.
