Answer:
70 - 79
Step-by-step explanation:
The mode interval is the interval with the largest frequency.
From the heights of the bars we see that this is 70 - 79
Answer:

Step-by-step explanation:
There are
2 yellow
3 magenta
5 blue
marbles in the bag.
So total of 2 + 3 + 5 = 10 marbles
We have to multiply the probability of yellow on first pick by the probability of yellow on second pick (WITHOUT REPLACEMENT).
We denote P(Y1) as probability of yellow on first draw &
P(Y2) as probability of yellow on second draw
Thus,
P(Y1) = 2/10 = 1/5 [since 2 yellow and 10 total marbles]
Now,
P(Y2) = 1/9 [since now 1 yellow is taken out and NOT replaced, so we have 1 yellow remaining and total 9 marbles]
Now, we multiply:
P(Y1) * P(Y2) = 1/5 * 1/9 = 1/45
The probability is 
Answer:
She will be able to make 8 wreaths
Step-by-step explanation:
I got my answer by first converting 3 1/4 into 13/4. I then divide 28 by 13/4 which was multiplying 28 by 4/13.
I got 112 when I did 28 × 4
I then divided 112 by 13
and got 8.615.
Since they are asking for how much wreaths she could make, it is going to be 8
Answer: 364 with a remainder of 28
Step-by-step explanation:
14952/41
41 goes into 149 3 times
149 - (41 *3)
149 - 123 = 26
41 goes into 265 6 times
265 - (41*6)
265 - 246 = 19
41 goes into 192 4 times
192 - (41*4)
192 - 164 = 28
So 14952/41 = 364 with a remainder of 28
To estimate an answer to this problem, you must first estimate the numbers as well. 189 would round to 190, and 643 would round to 640. Now you would subtract 190 from 640, giving you 460.
