Answers

Answer:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

See attachment for the graph of the equation.

Step-by-step explanation:

Given equation:

\(y=\dfrac{1}{3}x\)

To complete the table, find the corresponding values of y by substituting each given value of x into the equation.

\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)

\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)

\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)

Therefore the completed table is:

\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

To graph the equation, plot the ordered pairs on the given coordinate plane:

(6, 2)(12, 4)(18, 6)

Draw a straight line through the points.  (See attachment).

I need some help for this and the graph wont let you use decimals as the answer. Tip: 1/3 = 0.3 .
(6,2),(12,4),(18,6) would be correct

Answers

Answer:

Step-by-step explanation:

you are completely right please follow your heart <3

It’s actually D.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Formula for mean in grouped data

= Zfx/ Zf

f = sum of the number of mice

= 35

Frequency = 39 + x

Mean = 7

Fx = 20 + 78 + 112 + 8x + 54

= 264 + 8x

7 = 264 + 8x/ 39 + x

7(39+x) = 264 + 8x

After solving you will get

x = 9

Triangle Area

To get the area of a triangle the formula is a=b*h*1/2, so base is 3 and height is 3, we would do 3*3*1/2 which equals 4.5

but you have 2 triangles so multiply 4.5*2 and that's 9.

Convert 25 kilometers ran in 10 hours to a unit rate. Use the label kilometers per hour (kph).

Answers

Answer:

Step-by-step explanation:

Speed is distance divided by time. Simply put, if you drove 60 kilometres for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h. Let's take a more complex example: what's the average speed if you covered 425.5km in 5 hours 22 minutes and 30 seconds?

Simply divide 60 by your pace. When you aren't using whole hours in the calculation, convert the number to minutes, then multiply the result by 60 minutes per hour to get miles per hour or kilometers per hour.
