100 POINTS+BRAINLIEST 8TH GRADE MATH PT 5: WRITE THE EQUATION OF A LINE- this one was strange because the slope is supposed to b

Finger [1]

Answer:

$\textsf{b.} \quad 3x+5y=2$

Step-by-step explanation:

Define the given points:

$\textsf{let}\:(x_1,y_1)=(4,-2)$

$\textsf{let}\:(x_2,y_2)=(-1,1)$

Use the slope formula to determine the slope of the line:

$\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-(-2)}{-1-4}=\dfrac{1+2}{-1-4}=-\dfrac{3}{5}$

Use the point-slope formula to determine the equation of the line.

$\implies y-y_1=m(x-x_1)$

Substitute the found slope and point (4, -2):

$\implies y-(-2)=-\dfrac{3}{5}(x-4)$

$\implies y+2=-\dfrac{3}{5}(x-4)$

Multiply both sides by 5:

$\implies 5(y+2)=-3(x-4)$

Expand the brackets:

$\implies 5y+10=-3x+12$

Add 3x to both sides:

$\implies 5y+10+3x=-3x+12+3x$

$\implies 3x+5y+10=12$

Subtract 10 from both sides:

$\implies 3x+5y+10-10=12-10$

$\implies 3x+5y=2$

AnnyKZ [126]

Answer:

a) In the interval ( 55,9 ; 456,7 ) we will find 99,7 % of all values

b) In the interval ( 122,7 ; 389,9 ) we find 95,4 % of all values

Step-by-step explanation:

For a Normal distribution N (μ ; σ ) the Empirical rule establishes that the intervals:

( μ ± σ ) contains 68,3 % of all values

( μ ± 2σ ) contains 95,4 % of all values

( μ ± 3σ ) contains 99,7 % of all values

If N ( 256,3 ; 66,8 )

σ = 66,8 ⇒ 3*σ = 3 * 66,8 = 200,4

Then: 256,3 - 200,4 = 55,9

And 256,3 + 200,4 = 456,7

a) In the interval ( 55,9 ; 456,7 ) we will find 99,7 % of all values

b) 2*σ = 2 * 66,8 = 133,6

Then 256,3 - 133,6 = 122,7

And 256,3 + 133,6 = 389,90

Then in the interval ( 122,7 ; 389,9 ) we find 95,4 % of all values
