Answer:

Step-by-step explanation: standard score is equal to sample mean - population mean all over standard deviation.

Z=×-u/sigma. Where sigma is standard deviation. 267985-254876=13109. 13109/5834=2.247. Therefore the standard score is 2.247. The price they paid for the house is usual.

KL = 4x +3.<br> JK = 4x + 2, and<br> JL = 45<br> Find KL.
lbvjy [14]

Answer:

KL=23

Step-by-step explanation:

We are given the length of the whole line and its two halves. Since JK and KL make up the line JL, adding them together would make the line JL.

(4x+3)+(4x+2) = 45

8x+5=45

8x=40

x=5

Now we can plug the value of x back into the expression we were given for the line KL.

4(5)+3

23
