Since it's 50mL of hardener added in ONE container of resin, you multiply 50 and 15
50mL times 15= 750mL
Hope this helps.
Answer:
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.

Answer:
4/35 lottery is easier to win.
Step-by-step explanation:
For the 5/48 lottery, the winning probability is
≈0.1042
For the 4/35 lottery, the winning probability is
≈ 0.1143
Since

, the lottery where one chooses 4 of the numbers 1 through 35 is easier to win.
Answer: Choice D

=====================================================
Explanation:
The left portion is the interval (-∞, -2)
This is a shorthand way of saying 
The curved parenthesis says "do not include this endpoint as part of the solution set". Note the open hole at x = -2 in the diagram.
In contrast, the value x = 4 is included (due to the filled in circle), so we use a square bracket for this endpoint. Therefore, the right-hand portion is represented by [4, ∞) which translates to 
Negative and positive infinity will always use a parenthesis, and never a square bracket. This is because we can only approach infinity but never reach it, so we cannot include it as an endpoint.
All of this builds up to the full interval notation to be 
The only square bracket is near the 4; everything else is a curved parenthesis. This is why choice D is the final answer.
