Answer:
0.006 is the probability that the record will be broken in next year.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 62 seconds
Standard Deviation, σ = 0.8 seconds
We are given that the distribution of face time is a bell shaped distribution that is a normal distribution.
Formula:
The record will be broken if the time is less than 60 seconds.
P(time is less than 60 seconds)
P(x < 60)
Calculation the value from standard normal z table, we have,
Thus, 0.006 is the probability that the record will be broken in next year.
Answer:
1) triangular garden is larger
2) 1.46 square feet
3) 56.5 square inches
4) 557.1 sq in
5) 216 sq in
Step-by-step explanation:
1) Area of circlular garden: 78.54
Area of triangle garden: 80
2) 80 - 78.54 = 1.46
3) 12/2 = 6
= 113.1
113.1/2 = 56.5
4) area of square: 20(20) = 400
area do semicircle: /2 = 157.1
400 + 157.1 = 557.1
5) square: 144
triangle: 144/2 = 72
144 + 72 = 216
