Answer:
3/12 simplified to 1/4
Step-by-step explanation:
When two fractions in an equation have the same denominator, you can easily subtract/add the numerator, so:
9 - 6 = 3
3/12
If you need to simplify your answer, your answer is 1/4
When simplifying this fraction, three is a multiple of 12 and 3 (called the common factor)
3 divided by 3 is 1
12 divided by 3 is 4.
The equation that would best describe the situation would be the first option. To solve this question, simply break down the question into sections and then use variables X and y to represent each of the things asked for in the problem. We know the following:
X = no of tetra fish
Y = no of goldfish
If there is twice as much goldfish than tetra fish, then it would be 2y.
X = 2Y.
Then knowing what X and y represent, find the equation that gives the total cost of fish he bought, knowing that 1.50 is for a goldfish and 2.00 is for a tetra fish.
Answer:
Yes, Sample is good.
Step-by-step explanation:
The sample is a subset of the population, we take a sample because sometimes it is not possible to work on the whole population or it is quite costly or the time has taken so we work on sample.
Characteristics of Good Sample:
- The choice of the sample should be unbiased that means there should be an equal chance of selecting each unit.
2. It should be representative of the sample.
3. The choice of the sample should be flexible.
Since here she did not do any bias in selecting a sample. Here the choice of sample is independent and each unit has an equal chance of being selected in a sample. So, the choice of sample is quite good.
Answer:
1. x≈1.4825
2. x≈2.26531
Step-by-step explanation:
Answer:
b. 61.75
Step-by-step explanation:
Split it into a rectangle and a triangle
1. Rectangle
You can see that the side lengths are 7 and 6.5, so the area is 7 * 6.5 = 45.5
2. Triangle
You know that the base is 6.5 and that the height is 5 (because 12 - 7 = 5) so you can find the area by doing 6.5 * 5 / 2 = 16.25
3. Total
Add the two areas, so 45.5 + 16.25 = 61.75
