<u>Answer:</u>
Area = 150 m²
Volume = 125 m³
<u>Step-by-step explanation:</u>
• The surface area of a cube is given by the formula:
where r is the length of an edge of the cube = 5 m.
∴ Area = 6(5)²
= 6(25)
= 150 m²
• The volume of a cube is given by the formula:
∴ Volume = (5)³
= 125 m³
Answer:
Required probability is 0.19
Step-by-step explanation:
The two-way table for the given data is,
Fiction Non-Fiction Total
9th grade 35 8 43
10th grade 52 12 64
Total 87 20 107
It is required to find the probability of the students who prefer to read non-fiction novels, given that they are in 9th grade.
That is, to find the conditional probability .
Now,
So, we get,
<em><u>Solution:</u></em>
Given that,
We have to simplify
We can simplify the above expression by combining the like terms
Like terms are terms that has same variable with same exponent and same or different coefficient
From given,
Group the like terms
Thus the given expression is simplified
