Answer:
d) (179.20, 212.716)
Step-by-step explanation:
1000 : 345
569 : 195.96
Midpoint of (179.20, 212.716) is 195.958 which is the closest to 195.96
Answer:
RS = 32
Step-by-step explanation:
Set-up equation like this -- 2x+6+16=4x-4
Solve for x
Then plug x in for the length of RS. You should get 32 for RS.
Only problem is with the simplifying.
We all know that 5/5 = 1, it is natural to assume (x+a)/(x+a) is also 1, but in some cases where x+a=0, it is undefined. In this equation, where they simplify (x-2) and (x-6), you must say that x is not 2 nor 6 or, you just delete 0/0 which is undefined.
Therefore the only solution would be x=-1

i am 99.99% sure it is c
Answer: 0.84134
Step-by-step explanation:
We need to find the z-score for the given information first since this will help us find the probability. The formula for this is
Z score = 
We have
66 inches (the raw score)
70 inches (the population mean)
= 4 inches (the standard deviation)
This gives
Z score = = 
If you use a calculator, or a Z-score table then P(x > Z) is just P(Z > -1) which gives a probability of 0.84134.
