Answer:

Percent diagram helps to display information, making it easier to solve for what is missing.

A diagram is a way to help your brain process a lot of information at once. It is a visual planning tool that takes some of the pressure off of remembering every single detail. Sometimes we have hard questions that require sifting through a lot of information to figure them out.

This type of chart or diagram gives a quick, easy way to see how a whole is divided into its constituent parts.

Hatshy [7]

Answer:

1, 3, and 4 would be correct answers

Step-by-step explanation:

1.) -x - 2x - 3y - 2y + 1 + 1 = -3x -5y + 2

2.) -3x + 2y + 3y + 2 = -3x + 5y + 2

3.) -3x - y - y - y - y - y + 2 = -3x - 5y + 2

4.) -x - x - x - y - y - y - y - y + 1 + 1 = -3x - 5y + 2

5.) x + x + x + y + y + y + y + y + 1 + 1 = 3x + 5y + 2

Hope this helps!

Omar broke a cell sample into 8 batches, each

Nady [450]

Step-by-step explanation:

we have 8 equally "heavy" batches.

one weighs 3.9 × 10^-10 g

so, the total sample then weighed

8 × 3.9 × 10^-10 = 31.2 × 10^-10 = 3.12 × 10^-9 g

A triangle contains angles mesuring 28 degrees and 37 degrees. How many degrees is the third angle?

Orlov [11]

Answer:

115°

Step-by-step explanation:

We know that:

Angles ∠A and ∠B are 28° and 37°.

We don't know:

Angle ∠C's angle

So, we do this:

Add the 180°
Solve the equation 180 - 28 - 37

Solve:

180 - 28
= 152 - 37
= 115.

Angle ∠C is 115°.

8. A company makes electronic components for TV's. 95% pass final inspection (and 5% fail and need to be fixed). 120 components

Taya2010 [7]

Using the binomial distribution, it is found that the variance of the number that pass inspection in one day is 5.7.

For each component, there are only two possible outcomes, either it passes inspection, or it does not. The probability of a component passing inspections is independent of any other component, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability, and has variance given by:

$V(X) = np(1 - p)$
