Herta wants to build a picket fence in her front yard. Her design has fence posts that are 8.5 feet apart, with 19 pickets between each set of posts. If the pickets are 3 inches wide, how wide should the gaps be so that everything is evenly spaced?

Answers

8.5 Feet  = 102 inches

Pickets = 19 x 3  = 57 inches

Remaining = 102 inches - 57 inches = 45

If you put 19 pickets, there will be 20 gaps

So each will be 45 / 20 = 2.25 inches wide

Add three data values to the following data set so the mean increases by 10 and the median does not change. {42, 37, 32, 29, 20}

Answers

Sum of the numbers in the set: 42+37+32+29+20 =160

Current mean: 160/5 = 32

Median = the valvue of the middle = 32.

New mean: 32+10= 42.

Sum of numbers in the new set = 42*8 = 336

Difference: 336 - 160 = 176

I want to include 32, so that the new median stays in 32.

So the other two numbers must add 176 - 32 = 144

I will use a smaller number than 32 and the other greater (again in order to  keep the same median.

I will choose 28 and 144 - 28 = 116.

So my three new numbers are 28, 32 and 116 and the new set is {116, 42, 37, 32, 32, 29,28, 20}

Checking:

Sum of the terms: 116+42+37+32+32+29+28+20 = 336

Mean = 336 / 8 = 42, which is 10 more than the original mean.

And the new median is (32+32)/2 = 32. The same of the original set.

How many solutions does the system of equations have? A) No solution

B) One solution: x = 0, y = 0

C) One solution: x = 1, y = 5

D) Infinite many solutions

Answers

Answer:

no solution

Step-by-step explanation:

a solution would mean a point where the two lines cross. theres no such thing for parallel lines.

but if the lines are the same, they are parallel and cross everywhere, that would give infinite solutions.

if they would cross once, it would mean one solution
