U could answer that question by adding 2.45+1.9=4.35
Speed = distance / time
Speed = 120 / 33
Speed = 3.64 miles per hour
Answer:
7/10 or 70%
Step-by-step explanation:
6 red chips, 10 blue chips, and 4 yellow chips = 20 chips
P( not red) = not red chips / total
= (blue + yellow) / total
= (10+4)/20
=14/20
=7/10
= 70%
Answer:
Step-by-step explanation:
a)
- p = Total Number of Defects / Sample Size x Number of Samples
- z = Number of standard deviation = 3
- σ = Standard deviation of sampling distribution
- σ = p (1- p) / n = 0.0336 (1- 0.0336) / 300 = 0.0336 x 0.9664 / 300 = 0.0104
- Here, n = number of observations in each sample
- UCL = p+zσ = 0.0336 + 3(0.0104) = 0.0336 + 0.0312 = 0.0648 = 0.065
- LCL = p-zσ = 0.0336 - 0.0312 = 0.0024 = 0.002
b) Hence, Lower control limit cannot be a negative number as percent defective cannot be a negative number. As such, No. Percent of defective records cannot be a negative number.
The product would be 40.
First, solve what is in parenthesis (). (4x2) is equal to 8. 5 x 8=40, so
5 x (4 x 2) = 40
