Answer:
y = -5x + 4
Step-by-step explanation:
y=Mx+b
To solve this problem, we use the formula:
z = (x – u) / s
where z is the z score value which can be obtained from
the tables, x is the sample value, u is the mean = 6.3 min, and s is the std
dev = 2.2 min
at P value = 0.90, the z = 1.28, finding for x:
x = z s + u
x = 1.28 * 2.2 + 6.3
x = 9.116
at P value = 1.0, the z = 3.49, finding for x:
x = z s + u
x = 3.49 * 2.2 + 6.3
x = 13.978 ~ 14
Therefore the longest 10% calls last about 9.1 minutes to
14 minutes
1. 86/2=43/new price of one shirt
2. 43-15=28/original price of one shirt
Your answer would be $28.
Answer:
It equals 74.88
Step-by-step explanation:
U jus multiply them
28 + 6 = 34 and 34 - 3 = 31!!!!!!!
