Answer:
25inch
Step-by-step explanation:
Ok so there is something called a Pythagorean theorem.
It's a²+b²=c²
It works on right triangles
C is the longest side or the side not touching the right angle
and a and b is the other 2 sides
so the missing side is 24²+7²=Missing side or c²
24²=576 and 7²= 49
576+49=625
=25
The procedure is to make the difference of the terms that occupy the same position (column and row):
| - 6 - 4 | | - 5 5 | | - 6 + 5 - 4 - 5 | | -1 - 9 |
| 6 0 | - | - 4 -1 | = | 6 + 4 0 + 1 | = | 10 1 |
| 6 4 | | 6 - 4 | | 6 - 6 4 + 4 | | 0 8 |
Answer: option B.
Hi there!
The correct answer is 6.25 times.
This is how you get there:
1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm
2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25
If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.
I hope that I have been able to simplify this problem for you!

To solve for proportion we make use of the z statistic.
The procedure is to solve for the value of the z score and then locate for the
proportion using the standard distribution tables. The formula for z score is:
z = (X – μ) / σ
where X is the sample value, μ is the mean value and σ is
the standard deviation
when X = 70
z1 = (70 – 100) / 15 = -2
Using the standard distribution tables, proportion is P1
= 0.0228
when X = 130
z2 = (130 – 100) /15 = 2
Using the standard distribution tables, proportion is P2
= 0.9772
Therefore the proportion between X of 70 and 130 is:
P (70<X<130) = P2 – P1
P (70<X<130) = 0.9772 - 0.0228
P (70<X<130) = 0.9544
Therefore 0.9544 or 95.44% of the test takers scored
between 70 and 130.
