Answer:
Step-by-step explanation:
6,0 would be your coordinates
2,4
6,12
meaning that the numbers are multiplied by three. you can see the points without having to plot it on a graph
We need graphs to choose from sweetie
Answer:
1. 120
2. 2600
Step-by-step explanation:
6% of 2000 = 120
2000+120(5)
2000+600
=2600
Answer:
Step-by-step explanation:
Given the expression:
First, we open the outer brackets
Therefore:
Answer:
Step-by-step explanation:
The number of samples is large(greater than or equal to 30). According to the central limit theorem, as the sample size increases, the distribution tends towards normal. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 22199
σ = 5300
n = 30
the probability that a senior owes a mean of more than $20,200 is expressed as
P(x > 20200)
Where x is a random variable representing the average credit card debt for college seniors.
For n = 30,
z = (20200 - 22199)/(5300/√30) =
- 2.07
Looking at the normal distribution table, the probability corresponding to the z score is 0.0197
P(x > 20200) = 0.0197
