Allen wants to have a mean of 90 on his math quizzes. So far, he has scored 86, 94, 88, 95, and 89. What is the least score that
viva [34]

Answer:

88

Step-by-step explanation:

\frac{86 + 94 + 88 + 95 + 89 + x}{6}  = 90

The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.

Solve for x:

86 + 94 + 88 + 95 + 89 + x = 540

452 + x = 540

x = 88

Thus, Allen needs at least an 88 to obtain a mean of at least 90.

At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3.
frez [133]

Answer:

0.3

Step-by-step explanation

The formula to find density is m/v=p

m=mass

v=volume

p=density

<h3>---------------------------</h3>

All we have to do is plug in 6g and 20cm^3

This will give us 6/20 which simplifies to 3/10

With this you can easily figure out that the decimal for 3/10 is 0.3

So the density of the ice is <u>0.3</u>

<u>Hope this helped!</u>

Can someone give me some tips of how to study. I have already tried writing everything in my lesson but it doesn't seem to work
Ainat [17]
Study all notes, reread the chapters again. Have someone ask questions on the chapters page by page. This always has worked for me. Plus try to do this again the night before the test. You will be surprised how much you can remember by doing it again the night before the test. Hope this helps.
