Answer:
y = -3
Step-by-step explanation:
The equation of the line is y = -x -2
We plug in the given x value into the equation to find y.
y = -(1) - 2
Simplify.
y = -3
Permutation:
5! = 5 * 4 * 3 * 2 * 1 = 120
Answer:
It's a negative 4 and the variable n and can be used for anything or any equation.
Answer:
216 marbles bought altogether
Step-by-step explanation:
small m- 10
large m- 8
10×12+8×12=
120+96
= 216
Answer:
Provided that the sample size, n, is sufficiently large (greater than 30), the distribution of sample means selected from a population will have a normal distribution, according to the Central Limit Theorem.
Explanation:
1. As n increases, the sample mean approaches the population mean
(The Law of Large numbers)
2. The standard error of the sample is
σ/√n
where σ = population standard deviation.
As n increases, the standard error decreases, which means that the error
between the sample and population means decreases.
