Answer:
7/23
Step-by-step explanation:
Multiples of 4 are 4 and 8
4 was spun 4 times
8 was spun 3 times
total spins = 2+3+2+4+5+3+1+3=23
P( 4 or 8) = number of times spun / total
= (4+3) / 23
=7/23
Answer: 3
Step-by-step explanation:
Let's create a model first.
The initial fee is $19 (this is our y intercept or b)
And the pay per is $4 (this is our variable or m)
y=mx+b
y= 4x+19
To find out what the maximum number of events someone can attend for $31, we plug in different number for the x value until it's less than or equal to $31
In this case, plugging in 3 for x gives us exactly $31
y=4(3)+19= 31
Hi- I'm not sure what they mean by place value. But hopefully this helps.
A: Lee needs 370 pencils and wants to buy them by the box. There are 10 in a box so we need to divide 370 by 10.
370/10= 37
So he would need to buy 37 boxes
B: A carton has 10 boxes and each box has 10 pencils so first we need to find out how many pencils are in a carton:
10*10=100
To get 370 pencils, Lee would have to buy 4 cartons totaling 400 pencils
Answer:
Total number of ways are 336.
Step-by-step explanation:
It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find .
