Answer:
Step-by-step explanation:
Given
-- total
--- defective
--- selected
Required
The probability of rejecting the batch
This means that at least one of the selected piece is defected.
So, we first calculate the probability that all the selected piece are accepted.
So, we have:
The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs
So, we have:
Using the complement rule, the probability that the batch will be rejected is:
Options :
A cookies per pound
B. O pounds per hour
c. cookies per hour
D. hours per cookie
Answer: C.) Cookies per hour
Step-by-step explanation:
Given the following :
Number of cookies baked = 225 cookies
Total time taken = 5 hours
Amount of sugar used = 8 pounds
Tara divides 225 by 5; 225 / 5 = 45
Rate gives the amount or number of times something occurs within a given period, Hence
The rate obtained by Tara corresponds to the ratio of ; (Total cookies baked / total time taken) = (225 / 5), this translates to the amount or number of cookies baked within an hour.
Answer:
for this one b=49.458
Step-by-step explanation:
Answer:
Slope (m) =ΔY
/ΔX
=-3/
1
=-3
n slope = -3
From equation [<u>-2</u>x-8]
m slope = -2
so B) m>n
Step-by-step explanation:
Answer:
120°
Step-by-step explanation:
Opposite angles in a cross of 2 lines like this are equal;
A = 120 and B = D = 60°
