B) 11
Step-by-step explanation:
The interquartile range (IQR) is defined as IQR = Q3 - Q1 where Q3 represents the upper quartile and Q1 represents the lower quartile.
In a box-and-whisker plot, Q1 is the leftmost edge of the box, so Q1=38. Q3 is the rightmost edge of the box, so Q3=49
Therefore, the interquartile range is IQR = Q3 - Q1 = 49 - 38 = 11

Mrs. Suarez sold pies for a fundraiser. she sold 3 5/6 pies the first day and 1 3/6 the second day. how many pies did she sell in all. using number line
Answer: 5 2/6
Step-by-step explanation: 3 5/6 + 1 3/6 = 5 2/6 because you need to add the pie wholes,(3 + 1) and then you have the fractions, 5/6 + 3/6. So since all you need to make another whole is 1/6 you take it away from 3/6 and give it to 5/6 so now you have another whole. 4 wholes plus 1 new whole is 5 wholes. Since you took 1/6 away from 3/6 you now have 2/6. So 5 wholes and 2/6 were sold.
3 5/6 + 1 3/6 =
3 + 1= = 4
5/6 + 1/6 = 1
3/6 - 1/6 = 2/6
4 + 1 = 5
5 + 2/6 = 5 2/6

it cost benjamin 1.35 to send 9 text messages. How much would it cost to send 118 text messages?
price of one message = 1.35 ÷ 9
1.35 ÷ 9 = 0.15
0.15 • 118 = ( 3 ÷ 20 ) • 118
118 • 3 = 354
354 ÷ 20 = 177 ÷ 10 = $17.7 to send 118 messages

Prime Factorization is basically just multiplying prime numbers to get a specific number.
I hope it helps! :)
Answer:
see image
Step-by-step explanation:
It is difficult to show work, unless you were taught to use a factoring tree (see image) or division tower (see image).
On the tree, the bottom row shows the final answer. On the towers, the prime factors all end up on the left or under the tower.
Basically, divide your number (the question/problem) by 2 if its an even number. And keep dividing by two until its not an even number anymore. Then divide by the next smallest prime number that goes into it (like 3 or 5 or 7 or 9 or 11...) When the result is a prime number, then you are done. See image.

James drove 200 miles in 4 hours. If he continues to travel at this rate, how long will it take James to travel 150 more miles?
Answer:
3 hours
Step-by-step explanation:
it will take him 3 more miles because:
200 miles divided by 4 hours = 50
