Nastasia [14]

Answer: 20 names from each grade

Step-by-step explanation:

The two answers it comes down to are between every student from all of her classes and 20 students from each grade, however since the poll wants to determine how many people across the entire student body would attend, pulling from just Miranda's classes would add a grade level bias to the dance and would not be entirely random. 20 students from each grade is completely unbiased and properly represents the entire student body.

hram777 [196]

Answer:

125 blue vehicles

Step-by-step explanation:

In this question, we are going to estimate the number of vehicles of a specific color given that there are some numbers of both vehicle models present in a sample.

Now to solve this question, we are going to treat the sample numbers as a ratio.

The ratio here is thus 7 black to 5 blue I.e 7:5

We have 300 vehicles, we now want to estimate the number of blue vehicles present.

From the sample ratio, there are a total of 12 vehicles

Now the total number of blue vehicles would be 5/12 * 300 = 125

There are 125 blue vehicles

Angle sum theory find Y
kompoz [17]
<h3>Answer:</h3>

25

<h3>Step-by-step explanation:</h3>

The angle sum theory says that the sum of all the interior angles in a triangle is 180 degrees.

Finding X

To solve for y, we must first find x. This way we know 2 of the interior angles. Luckily, angle x is a part of a linear pair.

  • Linear Pairs are 2 adjacent angles that create a straight line together. This means that the sum to 180 degrees.

Angle x and the angle with a measurement of 115 form a linear pair. Thus, we can create an equation to find x.

  • 115 + x = 180

By subtracting 115 from both sides we know that x = 65.

Solving for Y

Now that we know x, we can find y. We know that one of the interior angles is 65 and that the other is 90 degrees. The square marking the bottom angles in the middle show that they are right angles.

  • Right angles are usuaslly denoted with a square drawn in the angle and have a measurement of 90 degrees.

Lastly, we can create a formula to find y with the angle sum theory.

  • 90 + 65 + y = 180

Combine like terms

  • 155 + y = 180

Subtract 155 from both sides

  • y = 25

This means that the angle y is 25 degrees.
