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%

Answer:
He bought 20 shirts
Step-by-step explanation:
shirts -- x
pants -- 3/4 of x
Therefore,
He bought --- 28(3/4 of x) pants and 40(x) shirts.
So, 28(3/4 of x) + 40(x) = 1220
=> 21x + 40x = 1220
=> 61x = 1220
=> x = 20
He bought 20 shirts and 15 pants.
Thenks and meak me brainliest :))
