Step-by-step explanation:
soln:
let,
(x1,y1) =(2,4)
(x2,y2)=2,-7)
Now,
By midpoint formula,
×= <u>x</u><u>1</u><u>+</u><u>x</u><u>2</u>
2
= <u>2</u><u>+</u><u>2</u>
2
=<u>4</u>
2
=2,,
And,
Y=<u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2
=<u>4</u><u>-</u><u>7</u>
2
= <u>-</u><u>3</u>
2
Hence ,
The mispoint between points (2,4) and (2,-7) is (2,<u>-</u><u>3</u><u> </u><u> </u><u> </u><u>)</u>

Answer:
-5/3, or in decimal form, -1.666.
Step-by-step explanation:
a. -146 (3k+5) --- distribute the -146 to "3k" and "+5."
b. -438k - 730 = 0 --- get the variable k to one side of the equation.
c. -438k=730 --- divide by -438 on both sides.
d. the answer you get is 730/-438, which, in simpler terms, is -5/3, or -1.666.

Answer:
87.08% percentage of families spend more than $4000 annually on food and drink
Step-by-step explanation:
Given -
average annual expenditure on food and drink for all families is $5700
Mean 
= 5700
standard deviation 
= 1500
Let X be the no of families spend annually on food and drink
percentage of families spend more than $4000 annually on food and drink =
= 
= 
Using 
= 1 - 
= 1 - .1292
= .8708
= 87.08%
