Y= earnings of the electrician
x=hrs working
y=45x-20
Since he charges 45 dollars an hour you subtract 20, which is the amount he spends, and get the earnings of the day

Find a line perpendicular to -5y=-35/2x+10 that goes through point(7,4)
valina [46]

Answer:

y=-2/7x+6

Step-by-step explanation:

first write this in y=mx+b format, y=7/2x−2

then write the perpendicular line, which is the opposite & negative of m

y=−2/7x-2

then remove b

y=−2/7x+b

plug in the numbers

(7,4) y= 4 x=7

4=-2/7*7+b

b is 6

so put the numbers back in

y=-2/7x+6

hope this helps and have a great day

malfutka [58]

Answer:

Minimum 13

First quartile 16

Step-by-step explanation:

Rewrite the sample 20 70 13 15 23 17 40 51 in ascending order:

13  15  17  20  23  40  51  70

The minimum is 13.

The median is the middle number

13  15  17  20  23  40  51  70

The middle number between 20 and 23 is

\dfrac{20+23}{2}=21.5

Consider first half of the sample

13  15  17  20

The first quartile is the middle number of this part. The middle number of

13  15  17  20

is

\dfrac{15+17}{2}=16
