Answer:

52%

Step-by-step explanation:

40% nuts of 5kg = 40% × 5 = 2kg

56% nuts of 15kg = 56% × 15kg = 8.4kg

total of nuts in mixture = 2 + 8.4 = 10.4kg

10.4kg of nuts in 20kg = 10.4/20 = 52%

Answer:

The probability that both of Eduardo’s partners for the group project will be girls is        

Step-by-step explanation:

Given : A hat contains slips of paper with the names of the 26 other students in Eduardo’s class on them, 10 of whom are boys. To determine his partners for the group project, Eduardo has to pull two names out of the hat without replacing them.

To find :  What is the probability that both of Eduardo’s partners for the group project will be girls?

Solution :

Total number of students = 26

Number of boys = 10

Number of girls = 26-10=16

Eduardo has to pull two names out of the hat without replacing them.

For the first hat,

Favorable outcome of getting girl = 16

Total number of outcome = 26

For the second hat, without replacement

Favorable outcome of getting another girl = 15

Total number of outcome = 25

The probability that both of Eduardo’s partners for the group project will be girls is

Hope This Helps :D
