Answer:
12 pizzas were ordered and Maribel only has 108 dollars.
12x12=144, 144-108=36, meaning that Maribel needs 36 more dollars for the whole number of pizzas. She could only get 9 pizzas instead of 12 because 12x9=108.
Step-by-step explanation:
Given that average age of employees of a large company is Normal
X - average age of employees
X:N(32,4)
The average age of employees in sales dept is 27 years.
Prob that an employee, chosen at random, will be younger than 27 years.
= P(X<27)
Let us convert x into Z
Z = (x-32)/4 = -5/4 = -1.25
Reqd prob = P(Z<-1.25) =0.5-0.3925
= 0.1075
Hence 10.56% is the correct answer.
13/52 is the ratio of hearts to all cards
That reduces to a 1/4 ratio
or a 25% chance of drawing a heart
3x=1x+5
