Answer:
B. 1.17
Step-by-step explanation:
The z-score is:
z = (x − μ) / σ
z = (67.1 − 64.4) / 2.3
z = 1.17
Length (L): 2w + 3
width (w): w
Perimeter (P) = 2L + 2w
60 = 2(2w + 3) + 2(w)
60 = 4w + 6 + 2w
60 = 6w + 6
54 = 6w
9 = w
Length (L): 2w + 3 = 2(9) + 3 = 18 + 3 = 21
Answer: width = 9 feet, length = 21 feet

Answer:
350 tickets
Step-by-step explanation:
if you do 42/350, it would equal 12%, so 350 is the total
This one I believe is easier than it looks. First you want to start by isolating the part with the exponent. To do this start by dividing both sides by (1/4) and you get….
(5/6)^x= (25/36)
Immediately, it’s noticeable that 25 is 5^2 and 36 is 6^2
So you can rewrite this equation as
(5/6)^x=(5/6)^2
Because the bases are the same now, all you need to do is solve for the exponents. In which you get x=2.
