By PEMDAS (or any alternative), <em>the first step should be to divide</em>, as D comes before A. So, 16 ÷ 4.
Hello!
<u><em>Answer: ⇒⇒⇒⇒⇒⇒⇒ =54</em></u>
_________________________________________________________________
Step-by-step explanation:
First you had to convert element to fraction.
Then you had to cross out by the common factor of 3.
Multiply by the fraction.
Multiply by the number.
Again multiply by the number.
Apply rule.
54 is the right answer.

Answer:
w=4
Step-by-step explanation:
Answer:
6 ft^2
Step-by-step explanation:
If the object in question is a cube, then we could say the length is 1, the depth is 1 and the height is 1, in which case each side of the cube has an area of 1 ft^2.
There are 6 such sides, so the total surface area is 6 ft^2.
Next time please be explicit in naming the shape, either verbally or with a diagram.
Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The sample proportion is
The margin of error is
Given that the confidence level is 95% the level of significance is mathematically represented as
Next we obtain the critical value of from the normal distribution table , the values is
The reason we are obtaining critical value of instead of is because
represents the area under the normal curve where the confidence level interval ( ) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the margin of error
Generally the margin of error is mathematically represented as
substituting values
=>
