Answer:

3.5 (D)

Step-by-step explanation:

focusing on the right side of the decimal, 5 rounds 5 to 6. 6 rounds 4 to 5. Anything 5 or above rounds up! So the .5 rounds 4 to 5, making the answer 3.5. So sorry if this doesn't make sense, its kind of hard to explain.

Samuel could round both of the individual numbers, to get s rounded answer. So, he could round 23 to 20, and 395 to 400, to get a product of 8000.
Or, he could multiply the numbers first, so 23*395 to get a product of 9085, which would then round to 9000, or depends on what place value it would want to be rounded to.

Given the Histogram that summarizes the data obtained by Kemala:

(a) The Class Width is the length of the intervals.

In order to find the Class Width, you need to subtract the lowest value of each bar from the lowest value of the previous bar.

In this case, you get:

$\begin{gathered} 5-2=3 \\ 8-5=3 \\ 11-8=3 \end{gathered}$

Therefore:

$Class\text{ }Width=3$

(b) You need to identify the number of beaches that had 10 or fewer pregnant turtles. Therefore, you need to add the corresponding number of beaches that correspond to these bars (A, B and C):

Then, you get:
