Answer:
The probability is 0.31
Step-by-step explanation:
In this question, we are tasked with calculating the probability that a random plumber called at Denver will charge an amount greater than $86 given the mean and the standard deviation.
Firstly, we calculate the standard score of $86 using the mean and the standard deviation.
Mathematically;
z-score = (x-mean)/SD
where x = 86, mean = 84 and SD = 4
z-score = (86-84)/4 = 2/4 = 0.5
Hence, we want to calculate P(z ≥ 0.5)
Using standard table
P( (z ≥ 0.5) = 1 - P(z ≤ 0.5) = 1 - ( 0.19146 + 0.5) = 0.30854
To the nearest hundredth = 0.31
Its option C
40 × (¹/₄)⁰ = 40
40 × (¹/₄)¹ = 10
40 × (¹/₄)² = 5/2
40 × (¹/₄)³ = 5/8
40 × (¹/₄)⁴ = 5/32
Mellisa will win because she has alot of balls
Convert all to liters
1000 ml=1L
therefor
1800ml=1800/1000L=1.8L
1 cup=0.236L
multiply
7.5 times 0.236=1.77
we have 1.9, 1.8,1.77
1.9 is greatest so Kanye drank the most water today
