<span>rectangle PQRS, PQ = 18, PS = 14, and PR = 22.8
so
</span><span>Diagonals PR = QS
if PR = 22.8 then QS = 22.8
TQ = QS/2 = 22.8 / 2 = 11.4

TQ = 11.4</span>
Mean can also be thought of as average.
Standard deviation is a bit more difficult to describe. It is a statistic that can help measure how spread out the data gets.
Depending on the distribution, data within 1 standard deviation of the mean can be considered fairly common and expected. Essentially it tells you that data is not exceptionally high or exceptionally low.
Answer:
y-6=-14/11(x+4)
Step-by-step explanation:
Answer:
d. 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
45a−25+7a=79
45a+−25+7a=79
(45a+7a)+(−25)=79(Combine Like Terms)
52a+−25=79
52a−25=79
Step 2: Add 25 to both sides.
52a−25+25=79+25
52a=104
Step 3: Divide both sides by 52.
52a
