Answer:

m=84

r:m = 1:7

therefore when r= 1 then M=14

$r = 12 \\ m = 7 \times 12 \\ m = 84$

I think that's how you do it

Here is a list of numbers: -5, -15, -10, 5, 14, 5, -18, 11, -4 State the median.

Rudik [331]

Answer:

Step-by-step explanation:

-18, -15, -10, -5, 4, 5, 5, 11, 14

There are 9 terms. So the one in the middle is the median.

-18, -15, -10, -5, 4, 5, 5, 11, 14

1 2 3 4 5 6 7 8 9

So 4 is the median.

Which quadratic equation has the roots -1+4i and -1-4i

AysviL [449]

Answer:

Step-by-step explanation:

Solve the quadratic in answer choice C using the quadratic formula:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$ .

Here a=1, b=2, and c=17.

Substitute and you'll have:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{-2+/-\sqrt{(-2)^2-4(1)(17)} }{2(1)}=\frac{-2+/-\sqrt{4-68}}{2)}$

$\frac{-2+/-\sqrt{-64} }{2}=\frac{-2+/-8i }{2}=-1+/- 4i$

Vem created a website for his school's sports teams. He has a hit counter on his site that lets him know

AlladinOne [14]

Using technology, the linear regression equation by fitting the data in the table is ŷ = 2.4x + 11. The predicted number of hits they will be recorded on day 15 is 47.

Using technology such as a regression calculator or excel ;

The regression equation which models the data is ;

ŷ = 2.4x + 11

Slope = 2.4 ; intercept = 11

The number of hits recorded on day 15 :

Substitute x = 15 into the equation :

ŷ = 2.4(15) + 11

ŷ = 47

Therefore, the predicted number of hits on day 15 is 47 hits.
