Answer: 1/4
Step-by-step explanation:
In a group of 84 kids 3/7 brought their lunches. This means that the number of kids that bought their lunches will be 3/7 ×total number of kids
= 3/7 × 84 = 36 kids
Of those who bought their lunches 9 got a slice of pizza. This means that 9 kids out of 36 got a slice of pizza.
Fraction of the students who bought their lunches and got a slice of pizza will be the number of students who bought their lunches and got a slice of pizza / the total number of students that bought their lunch. This becomes
9/36 = 1/4
The probability he will select a hockey card is 1/4, and then the probability that he selects a baseball card without replacement is 1/6.
So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.
Mean = 40 median = 37.5 mode = 30
