Answer:
0.1587 or 15.87%
Step-by-step explanation:
- Standardize and find your Z value as: Z = (82-75)/7 = 1.00
- Find in the Z score table the probability P( Z< 1.00), which is = 0.8413 = 84.13%
- Compute the complementary as (1-P), which is = 1 - 0.8413 = 0.1587 = 15.87%
Answer:
65.5 m
Step-by-step explanation:
Step 1. Find the width of the rectangle.
The formula for the area of a rectangle is
A = lw
Data:
A = 265.5 m²
l = 18 m
Calculation:
265.5 = 18w
w = 265.5/18 = 14.75 m
Step 2. Calculate the perimeter
The perimeter (P) of a rectangle is the sum of the lengths of its sides.
P = 2(l + w) = 2(18 + 14.75) = 2 × 32.75 = 65.5 m
The perimeter of the rectangle is 65.5 m.
Answer:
R = 5t
Step-by-step explanation:
given s is three times t then s = 3t and
R = 3t + 2t = 5t
