The slope of a line that goes through (2,3) and (4,6) is; Slope, m = 3/2

<h3>Slope of a line</h3>

The slope of a line defined by two points is given as;

Slope, m = (y2 -y1)/(x2 -x1)

Hence, for the given points;

Slope, m = (6-3)/(4-2)

Slope, m = 3/2

yanalaym [24]

Answer:

0.0313

Step-by-step explanation:

Given that in the shipment of 71 vials, only 13 do not have hairline cracks

Probability of not having a hairline cracks = $\frac{13}{71}$

If you randomly select 2 vials from the shipment

(Probability of not having a hairline cracks)' = $\frac{13-1}{71-1}$ = $\frac{12}{70}$

what is the probability that none of the 2 vials have hairline cracks.

i.e $(\frac{13}{71}) * (\frac{12}{70})$

= 0.183 × 0.171

= 0.0313

Hence, the probability that none of the 2 vials have hairline cracks = 0.0313

A department store sells logo shirts at an original price of $20. Every month that a shirt doesn’t sell, the store reduces the s

Tasya [4]

Given:
Original price = 20
reduces selling price by 25% every month it's not sold.

First markdown month:
20 * (100%-25%) = 20 * 75% = 15

Second markdown month
15 * 75% = 11.25

Macy, employee gets a 50% discount off the current price.
11.25 * 50% = 5.625
11.25 - 5.625 = 5.625 or 5.63

The pre-tax price of the shirt for Macy will be $5.63
