Answer:
1. Employees * Uniforms = Uniforms Needed
127 *3 = 381
2. Number Needed / Number per Package
381 / 8 = 47.625
3. Round up to Order 48 Packages
Step-by-step explanation:
Answer:
-2.5
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
-5
2
= -2.5
θ =
arctan( ΔY ) + 360°
ΔX
= 291.80140948635°
ΔX = 7 – 5 = 2
ΔY = -2 – 3 = -5
Distance (d) = √ΔX2 + ΔY2 = √29 = 5.3851648071345
Equation of the line:
y = -2.5x + 15.5
or
y =
- 5 x
2
+ 31
2
When x=0, y = 15.5
When y=0, x = 6.2
Answer:
The percent of the pairs that last longer than six months—that is, 180 days is 95.637%
Step-by-step explanation:
Mean = xbar = 208 days
Standard deviation = σ = 14
The standardized score for 180 days is the value minus the mean then divided by the standard deviation.
z = (x - xbar)/σ = (180 - 208)/14 = - 1.71
To determine the percent of boots that last longer than 180 days, we need this probability, P(x > 180) = P(z > (-1.71))
We'll use data from the normal probability table for these probabilities
P(x > 180) = P(z > (-1.71)) = 1 - P(z ≤ (-1.71)) = 1 - 0.04363 = 0.95637 = 95.637%
