Answer:
0.336
Step-by-step explanation:
Use binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Here, n = 8, r = 7, p = 0.8, and q = 0.2.
P = ₈C₇ (0.8)⁷ (0.2)⁸⁻⁷
P = 0.336

Answer:
It will take Jack 74 minutes(1 hour and 14 minutes) to complete the task
Step-by-step explanation:
From the question, we know that he has 1000 envelopes to stuff.
Now, he has already stuffed 112 out of the 1000. Number of envelopes left to be stuffed will be 1000 -112 = 888 envelops
We were told that it takes him 1 minute to stuff 12 envelopes.
Let the time it will take him to stuff 888 envelopes be x minutes;
Let’s have a relationship here;
12 envelopes = 1 minute
888 envelopes = x minutes
12 * x = 888 * 1
12x = 888
x = 888/12
x = 74 minutes
Answer:
69.66 Square inches
Step-by-step explanation:
Area of a Square = Length X Length
Length of the Square Pan =18 Inch
- Area of the Square Pan =18 X 18 =324 Square inches
Area of a Circle 
Diameter of the Pizza Pan =18 Inch
Radius =Diameter/2=18/2=9 Inch
- Area of a circular pan

Difference in Area =324-254.34
=69.66 Square inches
A pizza made in the square pan is <u>69.66 Square inches</u> larger than that made in a circular pan.
