Step-by-step explanation:

Since the total number of marbles is 40, that is our size of the sample. there are 16 red ones on that sample, so the probability of extracting a red marble from the box is given by the ratio of successes divided the total number of marbles:

Luana bought a new phone and plan. She paid $175. after three months, She paid $295. after 6 months. Write an equation that mode

elixir [45]

Answer: Hence, our required model will be

$C=40m+55$

Explanation:

Since we have given that

Luana bought a new phone and

For 3 months, the amount she paid = $175

For 6 months, the amount she paid = $295

Now, we have to model an equation ,

Here, let cost be 'C' and

Let number of months be 'm'.

So, we will use the "equation of line" i.e. for two point slope form :

Here y represented by 'C' and x represented by 'm'

So,

$C-C_0=\frac{295-175}{6-3}(m-m_0)\\\\C-175=\frac{120}{3}(m-3)\\\\C-175=40(m-3)\\\\C-175=40m-120\\\\C=40m-120+175\\\\C=40m+55$

Hence, our required model will be

$C=40m+55$

If a = i - 9k and b = j + k , find ab .

Orlov [11]

Answer:

solution

given a=1_9k and b=j+k

Now,ab=(1_9k)(j+k)

=1((j+k)-9k(j+k)

=j+k_9jk-9k^2

=k_9k^2+j_9jk

=k((1_9k)+j(1_9k)

=(1_9k)(k+k)

(Geometry HELP) The perimeter of WXY is ___ cm?

jeka57 [31]

I hope this helps you

QR=WS=2.93

RS=QW =2.04

QS=XR =2.28

RS=XQ=2.04

SY=QR =2.93

RY=QS =2.28

XY=XR+RY=2.28+2.28=4.56

XW=XQ+QW=2.04+2.04=4.08

WY=WS+SY=2.93+2.93=5.86

Perimeter of XYW=XW+WY+XY

Perimeter of XYW=4.08+5.86+4.56

Perimeter of XYW =14.5
