Answer:

Part A: The amount of students represented is around 68-69

Part B: You Can collect the data by using the dot plot, the units are text messages

Part C: How many students receive text messages over the weekend? This is a statical question because there’s more than one answer.

I’m not sure by the way, I hope it helps anyway. If this doesn’t work out then sorry :)

Gavin rides his bike to and from his grandparents each day. The one-day trip is 2.15 kilometers. How many kilometers will he tra

Lubov Fominskaja [6]

Answer:

Number of kilometers= 9.68 km

Step-by-step explanation:

Giving the following information:

Total trip= 2.15 kilometers

Number of days= 4.5 days

<u>To calculate the total number of kilometers traveled in 4.5 days is calculated using the following formula:</u>

<u></u>

Number of kilometers= kilometers per day*number of days

Number of kilometers= 2.15*4.5

Number of kilometers= 9.68 km

Find an equation for the line that passes through the points (6, -1) and (-6, 2).

kirill115 [55]

Answer:

$D : y = \frac{-1}{4}x + \frac{1}{2}$

Step-by-step explanation:

let D be the line that passes through the points (6, -1) and (-6, 2)

Then D has an equation of the form D: y = ax + b

Now we need to find a and b in order to be able to write the equation of the line D:

$a = \frac{-1-2}{6-(-6)}= \frac{-3}{12}= \frac{-1}{4}$

Since the point (6 , -1) lies on the line D then :

-1 = (-1/4) × (6) + b

then

-1 = (-6/4) + b

then

b = -1 - (-6/4) = -1 + 6/4 = -4/6 + 6/4 = (-4+6)/4 = 2/4 = 1/2

then

b = 1/2

Conclusion:

Since a = -1/4 and b = 1/2 then

$D : y = \frac{-1}{4}x + \frac{1}{2}$

A right triangle has a hypotenuse length of 13 units. One leg has a length of 12 units. Which equation can be used to determine

viktelen [127]

a = √(13² - 12²) units

<h3>Further explanation</h3>

<u>Given:</u>

A right triangle has a hypotenuse length of 13 units.
One leg has a length of 12 units

<u>Question:</u>

Which equation can be used to determine the length of the other leg?

<u>The Process:</u>

We will solve a problem regarding right triangles. In the process, there is a relationship between the Pythagorean Theorem with Exponent and Square Root.

Let us find out the equation to determine the length of the other leg. Let the length of the leg as "a".

The Phytagorean Theorem:

$\boxed{ \ (leg)^2 + (leg)^2 = (hypotenuse)^2 \ }$

$\boxed{ \ a^2 + 12^2 = 13^2 \ }$

Subtract by 12² on both sides.

$\boxed{ \ a^2 = 13^2 - 12^2 \ }$

To take the square root on both sides.

So here's the equation that can be used to determine the length of the other leg: $\boxed{\boxed{ \ a = \sqrt{13^2 - 12^2} \ }}$

- - - - - - - - - -

Notes

If we continue working on the above, the results will be as follows:

$\boxed{ \ a = \sqrt{13^2 - 12^2} \ }$

$\boxed{ \ a = \sqrt{169 - 144} \ }$

$\boxed{ \ a = \sqrt{25} \ }$

Hence the length of the other leg equal to a = 5 cm.

Of course, we agree with the use of the right intuition, which is to remember Pythagorean Triples, i.e., $\boxed{ \ 5-12-13 \ }.$ This method is very convenient when working on multiple-choice tests in a limited amount of time.
