Answer:
it has 7 zeros in total …
Step-by-step explanation:
answer for the problem .is 320000000.
count how many zeros ig.
There are 8 zeros at the end of the number [tex]2^{12} \times 5^7[/tex].
The given expression is [tex]2^{12} \times 5^7[/tex].
What are exponents?The exponent of a number shows how many times the number is multiplied by itself.
Now, the given expression can be rewritten as [tex]2^7 \times2^5 \times 5^7[/tex].
= [tex]2^7\times 5^7 \times2^5[/tex]
= [tex](2 \times 5) \times 10^7 \times 2^5[/tex]
= [tex]10 \times 10^7 \times 2^5[/tex]
= 100000000 × 32
= 3200000000
Therefore, there are 8 zeros at the end of the number [tex]2^{12} \times 5^7[/tex].

Step-by-step explanation:
Each side of the square is 5 units. The formula for area is Length times width, so its
5x5=25
but the formula for perimeter is length+width+length+width or length+width times 2
so you just add up all the side.
5+5+5+5=20
All sides are always gonna be the same size on a square so thats how we know they are all 5 units.
Hope this helped :)

Your test scores in one class are 80 and 88. What possible scores can you earn on your next test to have a test average between 84 and 89, inclusive?
Answer:
The average of your two scores to date is 84. You need the average of these two tests plus the next test to be between 84 and 89.
So, you need to solve for x, where 2/384 + 1/3x = 84. This will give you the lower end of your next test.
And you need to solve for y, where 2/384 + 1/3y= 89. This will give you the higher end of your next test.
The reason for the 2/3 in front of the 84 is because there are two tests there, and the reason for 1/3 in front of the unknowns is because that is just one test. Averages need to be weighted by number of observations.
I won't go through the algebra here, but the answers will be 84 and 99.
Step-by-step explanation:
Answer:
84 to 99
Step-by-step explanation:
If the goal for your average is 84, then your test scores total ...
(80-84) +(88-84) = -4 +4 = 0
relative to your desired average. This means your minimum score on the next test will need to be 84 -0 = 84.
__
If the goal for your average is 89, then your test scores total ...
(80-89) +(88-89) = -9 -1 = -10
relative to your desired average. This means your maximum score on the next test will need to be 89 -(-10) = 99.
To ensure a test average between 84 and 89, your next test score must be between 84 and 99.

Fifteen students in a class received the following scores on their last test:
15, 62, 65, 65, 71, 73, 74, 75, 75, 81, 83, 84, 88, 91, 96, 99
Which of these numbers could be considered an "outlier"?
An outlier is a data point that lies outside the overall pattern in a distribution.
__________________________________________________________
Here, we have 15, 62, 65, 65, 71, 73, 74, 75, 75, 81, 83, 84, 88, 91, 96, 99.
The outlier here would be 15 because compared to the other numbers 15 is not as close to 60-90 as the others are.
I hope my answer helped you! If you need more information or help, comment down below and I will be sure to respond if I am online. Have a wonderful rest of your day!
The outlier is:
⇨ 15Work/explanation:
An outlier is a data value that is the smallest/largest in the entire set and that is alot smaller/larger than the other values in the set. It can be considered the odd one out.
Here we notice that all the scores are clumped together (from 62 to 99) but one of them is further away than the other ones. That number is 15.
Hence, 15 is the outlier.please help i need to get this done :(
