1/6 because 2•1=2 and 3•4=12 and 2/12=1/6
Answer:a and b
Step-by-step explanation:
Answer:
Statistic
Step-by-step explanation:
Since, a characteristic of a sample is called statistic. It is used to estimate the value of a population parameter and can be computed from the sample.
Here, the sample is 104 children,
For which the average number of hours of sleep per night was 9.46 hours,
∵ 9.46 is the number that can be computed from the sample of 97 children.
Hence, the number 9.46 is a Statistic
Answer:
x -2y = -9
Step-by-step explanation:
We can start by swapping the coefficients of x and y, then negating one of them. We can finish by evaluating the expression at the given point to find the constant.
2x -4y = constant
2(1) -4(5) = -18 = constant
So, an equation could be ...
2x -4y = -18
We notice that all of the coefficients of this equation are divisible by 2, so we can remove a factor of 2 from the equation:
x -2y = -9
