Answer:
What is the probability that you will finish this quiz in 23.84 minutes or less?
0.03593
Write your answer as a percentage with 2 decimals
= 3.59%
Step-by-step explanation:
The z score formula is given as:
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean = 26 minutes
Standard deviation = 1.2 minutes.
The probability that you will finish this quiz in 23.84 minutes or less(≤) is calculated as:
z = (x-μ)/σ
z = 23.84 - 26/1.2
z = -1.8
Probability value from Z-Table:
P(x ≤ 23.84) = 0.03593
Converting to percentage
0.03593 × 100
= 3.593
Approximately to 2 decimal places = 3.59%
I think c and b are correct answers
The contestants total number of points is 20.
30 + 15 = 45
45 - 25 = 20 total points
To find the answer, take the measurement of an edge of the cube, multiply it by 6, and then square that number.
Ex:
Edge = 16
Faces in 1 cube = 6
6 * 16 = 96
96^2 (which is just 96 * 96)= 9,216
I hope this helps! :)
