5 0

Answer:

You can find and write the equations in Slope-Intercept form due to the slope and y-intercept.

Step-by-step explanation:

The Slope-Intercept Form Formula: y=mx+b

The m represents the slope while the b represents the y-intercept

You can also use y2 - y1 / x2 - x1 to find the slope which is the m in your formula.

Lastly, to find a y-intercept, you can plug in your coordinate for the x and y to do two-step linear equations.

miv72 [106K]

Answer:

6

Step-by-step explanation:

The mean of a list of test scores is 80

Adding an additional test score of 92 caused the mean to rise to 82

To find:

After this additional, how many total test are in the list ?

Solution:

Let the total number of test at first = n

And sum of total score = S

As we know, mean = \frac{sum \ of \ total \ observation}{number\  of \ total\  observation}

                    80= \frac{S}{n} \\

Multiplying both sides by n

80n=S

Now, as adding an additional test score of 92 caused the mean to rise to 82,

S+92=82\times(n+1)\\80n +92 = 82n+82           \  (given \ S =80n)

80n-82n =82-92\\-2n=-10

By dividing both sides by minus ( - )

2n =10

By dividing both sides by 2

n =5

Thus, total number of test at first = n = 5

And, after this additional score added, total number of tests are n+1=6

Brums [2.3K]

Answer:

42

Step-by-step explanation:

Number of students whose favorite class is Math:

60*0.85=51

Number of students whose favorite class is Science:

15% is equal to 0.15.

60*0.15=9

Subtract number of students who like science from number of students who like math.

51-9=42

42 more students in the survey prefer math over science.
