Corey used the regression equation y = 1.505x − 88.21, where x is the temperature and y is the number of swimmers, to determine

a possible outside temperature when 80 swimmers are at City Pool.
1. y = 1.505(80) − 88.21

2. y = 120.4 − 88.21

3. y = 32.19

4. If there are 80 swimmers at the pool, the temperature is likely to be 32.2°F.

Analyze Corey’s work to find his error. What is Corey’s mistake?

How do you break apart the factor 42 using place value?
worty [1.4K]

Hey there!☺

Let's break apart 42.

The 4 is in the tens. The 2 is in the ones.

                            Place Value starting from Thousands

                             Thousands  Hundreds  Tens  Ones

                             _________ ________ ____ _____

                                                                        4          2

So this is how we break up numbers using place value.

Hope this helps!

Which of the following could be the ratio of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse
Aliun [14]

Answer:

Option C is correct.

Ratio of longer leg to hypotenuse is;  \sqrt{3} : 2

Step-by-step explanation:

This is the special right angle triangle 30°-60°-90°  as shown below in the figure.

  • The side opposite the 30° angle is always the shortest because 30 degrees is the smallest angle.
  • The side opposite the 60° angle will be the longer leg, because 60 degrees is the mid-sized degree angle in this triangle.
  • Finally , the side opposite the 90° angle will always be the largest side(Hypotenuse) because 90 degrees is the largest angle.

In 30°−60°−90° right triangle,

  • the length of the hypotenuse is twice the length of the shorter leg,also
  • the length of the longer leg is \sqrt{3} times the length of the shorter leg.

Then:

the sides are in proportion i.e,  1:\sqrt{3} :2

Therefore, the ratio of the length of the longer leg to the length of its hypotenuse is:  \sqrt{3} : 2
