Answer:
Step-by-step explanation:
The given expression that represents the volume of the rectangular prism is:
We can rewrite this to reveal a perfect square pattern.
We factor using perfect squares to obtain:
Volume is three dimensional so we need a third factor different from 1.
We further factor one of the difference of two squares to get:
So pick the following unique dimensions from the possible answers:
Answer:
b = 46 - 31
Step-by-step explanation:
b = 46 - 31
b = 15
The boys (b) brought 15 paper towel tubes
If simplifying it means breaking it down with the answer it would be 1/5
Consider, ΔBCD, in rectangle,
cos 60 = b/24
1/2 = b/24
b = 12
Now, Sin 60 = p/24
√3/2 = p/24
p = 24√3/2 = 12√3
Area would be : Length * Width = 12 * 12√3 = 144√3 cm²
Answer:
5% significance level indicates the level of risk, error or exactness. It guides our conclusion on which hypothesis a data supports
Level of significance defined as the possibility, probability or chances of rejecting a null hypothesis when it's results is valid.
For every statistical hypothesis, the result has propency or likeliness to be exact or not. That is, it has chances of containing a type of error referred to as level of significance.
Now, a 5% significance level implies that, the statistical results or analysis has 95% reliability or confidence level.
In other words, a 5% significance level indicates that a result has 0.05 RISK level.
The level of significance is needed for every hypothetical test because it indicates validity of each hypothesis data. It gives confidence such that one is at peace to know the hypothesis a particular data supports
