Answer:

Step-by-step explanation:

Mark -2 on the graph for that is your y intercept. Move 7 units up from -2 and mark the point you land on. Then you move 7 units down from -2 and mark the point you land on. Draw a line connecting the 3 points and there you have your line.

Have a good day. :]

How do I start this problem? I don't need help with the graphing part.

tamaranim1 [39]

Answer:

x = 6 , y = 0 (x , y) = (6 , 0)

x = 12, y = 3 (x , y) = (12 , 3)

x = 24, y = 9 (x , y) = (24 , 9)

Step-by-step explanation:

Simply plug in a x, and find a y that would make the equation true:

When x = 6:

6 - 2y = 6

6 (-6) - 2y = 6 (-6)

-2y = 0

(-2y)/-2 = (0)/-2

y = 0

When x = 6, y = 0 (x , y) = (6 , 0)

When x = 12:

12 - 2y = 6

12 (-12) -2y = 6 (-12)

-2y = -6

(-2y)/-2 = (-6)/-2

y = 3

When x = 12, y = 3 (x , y) = (12 , 3)

When x = 24:

24 - 2y = 6

24 (-24) - 2y = 6 (-24)

-2y = -18

(-2y)/-2 = (-18)/-2

y = 9

When x = 24, y = 9 (x , y) = (24 , 9)

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 8.4 years, and standard deviation of

QveST [7]

Answer:

7.35 years

Step-by-step explanation:

Given that :

mean = 8.4

standard deviation = 0.6

From the negative z tables, the corresponding data for 0.04 = -1.75

So, using the z-score formula:

$z = \dfrac{x - \mu}{\sigma}$

$-1.75 = \dfrac{x - 8.4}{0.6}$

-1.75 × 0.6 = x - 8.4

- 1.05 = x - 8.4

x = -1.05 + 8.4

x = 7.35 years

the shortest lifespan will last less than 7.35 years

∴ the longest 4% will have lifespans longer than x = 8.4 + 1.75(0.6)

= 9.45 years

The Ratio of boys to girls at a middle school is 3:2. If the school has 400 people how many will be boys?

Mekhanik [1.2K]

You have to divide 400 by 5. That will equal 80. Since the ratio is 3:2 Just multiply 3 by 80 then 2 by 80! :-)

You can check it by simplifying it again.
