Answer:
The equation that best represent the situation is;
x^2 = 576
or x^2 -576 = 0
Step-by-step explanation:
Here, we want an equation that best represent the given information in the question.
The length of the garden is twice as long as it is wide
So, given that x is the length of the garden, then x/2 will represent the width of the garden
From the description given in the question, the garden would be rectangular in shape.
Mathematically, the area of a rectangle can be calculated using the formula;
L * B = area
Thus;
x * x/2 = 288
x*2 = 2 * 288
x^2 = 576
Answer:
The sampling used is simple random sampling.
Step-by-step explanation:
Consider the provided information.
Types:
- Simple random sample is a subset of the population chosen from a larger set. Every person is selected by chance and randomly.
- Systematic sampling: list of elements is counted off.
- Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.
- Cluster sampling: divide the population into groups, usually geographically.
- Stratified sampling: divide population into groups called strata. but this time population might be separated into males and females.
Here, randomly selected 60 customers, Thus, the sampling used is simple random sampling.
18=p+d+n, 3p=d, 2n=d
The lowest number that is divisible by 3&2 is 6 so, there is 6 nickels.
There is 6 nickels and there is half of that in dimes, 3 dimes.
There is three times the amount of pennies of dimes. 3*3=9. There is 9 pennies.
6 nickels + 3 dimes + 9 pennies= 18 coins
So Sahra is 3 times as old as her daugter. That means that the sum of their age is the daughters age times 4.
We can prove that by saying the daughters age is x. Sahra's age must be 3x. Their sum must be x+3x = 4x.
So to get the daughters age we divide the sum by 4, which is 8.
