Answer:
A) from the line of best fit, the approximately y-intercept is (0,1.8). This means without any practice, 1h.8 games are won.
B) slope: (5.6-1.8)/(2-0) = 1.9
y = 1.9x + 1.8
(Line of best fit)
x = 13,
y = 1.9(13) + 1.8 = 26.5
Predicted no. of games won after 13 months of practice is 26.5
inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
<u>Step-by-step explanation:</u>
Here we have , Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds.Dwight builds at most 9 models. We need to find Which inequality could be used to find the number of models Walt builds . Let's find out:
Let the the number Walt builds is x , So Dwight builds 7 fewer models than 4 times the number Walt builds i.e.
⇒ ![4x-7](https://tex.z-dn.net/?f=4x-7)
But , according to question Dwight builds at most 9 models i.e.
⇒ ![4x-7\leq 9](https://tex.z-dn.net/?f=4x-7%5Cleq%209)
⇒ ![4x\leq 16](https://tex.z-dn.net/?f=4x%5Cleq%2016)
⇒ ![\frac{4x}{4}\leq \frac{16}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%5Cleq%20%5Cfrac%7B16%7D%7B4%7D)
⇒ ![x\leq 4](https://tex.z-dn.net/?f=x%5Cleq%204)
Therefore ,
inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .

Answer:
A'B' = 3×AB
Step-by-step explanation:
Any linear measure on the scaled-up drawing will be the measure of the original, multiplied by the scale factor.
A'B' = 3×AB
No, i do not agree. To find this out, we will have to convert all of them into either decimals or percents. Let's convert these all into percents. A percent means 'out of 100', so if we add the percents all together, they should equal to 100. The rides is 50%. To convert 1/3 into a percent, divide the numerator by the denominator. You will get a decimal, so then multiply that by 100 or move the decimal two places to the right. So, 1 divided by 3 is equal to approximately 33%. Let's add 50 and 33 together. The total is 83%. So, like I said, a percent is out of 100. Subtract 83 out of 100 and you will get 17. So, the remaining percent has to be 17 percent, not 10%.
Hope it helps :)
