Step-by-step explanation:
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.
First name
Probability= Favourable outcome/Total outcome
Probability of girls=16
Total probability=26
Eduardo has to pull two names out of the hat without replacing them.
Probability= Favourable outcome/Total outcome
=16/26
=8/13
For the second name:
Without replacement of the first hat
Probability of girls=16-1=15
Total probability=26-1=25
Probability= Favourable outcome/Total outcome
=15/25
=3/5
Probability of both of Eduardo's partner for the group project will be girls=8/13*3/5
=24/65

Answer:
Step-by-step explanation:
let a be the number of tennis balls.
let b be the number of tennis rackets.
We write determine the ratio of balls to rackets by dividing the number of balls by the number of rackets:
For every one ball, there 5 thirds of a racket.
We plot this function on a graph to visualize our model;

</span>Finnegan needs to get the average of 70 in 4
tests in science to be able to make it to honour roll.
Find the lowest score he received on the fourth test if his first tests are 65,
60 and 92.
let x be the missing number
=> 65 + 60 + 92 + x / 4 = 70
=> 217 + x / 4 = 70
=> 217 + x = 4 x 70
=> 217 + x = 280
=> x = 280 – 217
=> x = 63
Thus the lowest score he get is 63.</span>
