Answer:

Kindly check explanation

Step-by-step explanation:

Given the data on the result of math exam in Ben's class

{35,42,56,68,69,72,72,77,78,78,82,85,87,88,90,93,94,96,96,99}

The 85th percentile score represents the score in which 85 percent of the students in Ben's class or below obtained in the test.

The 85th percentile score :

85%(n+ 1) term

n = number of observations = 20

0.85(20 + 1)th term

0.85(21) = 17.85 term

Take the average of the 17th and 18th terms

(94 + 96) / 2

= 190 / 2

= 95

Use pythagorena theorme

D=\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}
NOTE: x1 and x2 means the first x and second x, not x^1 and x^2

points given are
(1,1)
(5,6)
x1=1
y1=1
x2=5
y2=6
D=\sqrt{(1-5)^{2}+(1-6)^{2}}
D=\sqrt{(-4)^{2}+(-5)^{2}}
D=\sqrt{16+25}
D=\sqrt{41}

Answer:

y = 4x + 14

Step-by-step explanation:

slope-intercept form: y = mx + b

Slope formula: \frac{y2-y1}{x2-x1}

To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.

To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:

\frac{18-14}{1-0}

Simplify:

18 - 14 = 4

1 - 0 = 1

\frac{4}{1}=4

The slope is 4.

To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:

y = mx + b

18 = 4(1) + b

18 = 4 + b

14 = b

The y-intercept is 14.

Now that we know the slope and the y-intercept, we can write the equation:

y = 4x + 14

Solve the system by elimination <br> 2x+6y= -12 <br> 5x-5y= -10
kvv77 [185]
First thing you should do is reduce coefficients.

1st equation has all multiples of '2'. Divide by 2
---> x +3y = -6

2nd equation has multiples of 5. Divide by 5.
---> x - y = 2

Now elimination part is easier. 
Eliminate 'x' variable by subtracting 2nd equation from 1st.

   x + 3y = -6
-(x  - y = 2)
----------------------
       4y  = -8

Solve for 'y'
4y = -8

y = (-8)/4 = -2


Substitute value for 'y' back into 2nd equation:
x - (-2) = 2
x + 2 = 2
x = 0

Solution to system is:
x=0, y =-2
