Answer:
Step-by-step explanation:
You have 3 points and need to find ax2 + bx + c = y. First use (0,2). x is zero, so y = 2 = c. You have c. Now put (-1,0) into the equation. 0 = 1a -b + 2. Rearrange so you get b = a + 2. Now use the other point. a*(-2 squared) + b*(-2) + 2 = 0. Simplify and substitute (a + 2) for b and you will have the answer.
The answer to this question is false
Answer:
Answer: 1/10 of the store's total sales last month were in appliances (lower right corner)
Step-by-step explanation:
Explanation:
Let's go through the four possible answers
In the upper left corner it says "Total mobile phone sales is likely 27,000" which is a paraphrase of what is given. The chart gives 9000 as the phone sales for that one particular store. If all stores are identical in performance, then we have 4*9000 = 36000 in total mobile phone sales. Of course, it's impossible to know for sure how the other stores did. So we can eliminate this as one of the answers.
In the upper right corner, it says "13% of the stores sales was in car electronics" (also paraphrased). We have 13 thousand in car electronics out of 17+13+6+9+15 = 60 thousand total. Divide the two values: 13/60 = 0.2167 = 21.67% approximately. So we can eliminate this as an answer.
In the lower left corner, it says "the total sales is likely greater than $300,000" but we don't know for sure because again we don't have the other charts for the three other stores. Assuming the four stores perform the same, then we'd have 4*60 = 240 thousand as the total and not 300 thousand. It's safe to say we can eliminate this as an answer.
In the lower right corner, it says "1/10 of the stores sales were appliances". This statement is true. Why? Because 6 thousand is the sales figure for appliances out of 60 thousand total. Divide the values: 6/60 = 1/10. So this is why the lower right corner is the answer.
Number 1.) In game 1 he scored 180 points, In game 2 he scored 200 points this means the score went up , so now you have to add, ( Addition ).
180 + x = 200 | x=? , well 180 + 20 = 200.
Since there is 20 points added to 180 which gives us 200 there is an 11.11% increase .
__________________________________________________
Number 2.) , In the next game he scored 200 points , it asks what is the decreased number?
how many numbers did his score drop? 200 - 180 = 20 |
Now we must work backwards , There is a loss in points , ( 20 ) , so there is an 10% decrease.
(200-180) / 180 * 100% = 10%
20 / 200 * 100% = 10%
20 = The Answer with an 11.11% increase , there is a 10% decrease.
I hope this helps you a lot
