The problem indicates that A represents the number of tablet computers sold in millions. So, if 65 million were sold, we must substitute A = 65 to the equation. Then, we find for t.
65 = 4.5t² +43.5t + 17
Solving for t using a calculator,
t = 1 and -10.67
Let's take the positive root. So, t=1.
That means the year would be 1 year after 2010. <em>Therefore, the answer is 2011.</em>
Answer:
60ft
Step-by-step explanation:
I have not done this kind of work in a while but if you scale each side of the square by 6 is should increase to a perimeter of 60ft
Ratio of boys to girls= 17:3
number of people= 740
to find the number of boys out of 740 people, you have to add the ratio together and divide 740 by it. then multiply the answer by 17 because the ratio for boys is 17.
17+3=20
740÷20=37
37×17=629
answer= 629

Experimental methods involve the manipulation and control of variables, whereas non experimental methods require simple observation of the variables.
Answer: Option D.
<u>Explanation:</u>
Non-experimental research about doesn't mean nonscientific. Non-experimental investigate implies there is an indicator variable or gathering of subjects that can't be controlled by the experimenter. Test plan, then again, takes into consideration specialists to control the indicator variable and subjects.
Non experimental research falls into three broad categories: single-variable research, correlational and quasi-experimental research, and qualitative research.
For example let’s use something simple.
1+1 < 3+6
Why is this?
Because 1 +1 = 2 and that is less than 3 + 6 which is 9. Next time, apply this to something harder you might learn. I hope this helped <3
