Answer:
It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.
Step-by-step explanation:
Given that:
sample size n = 1600
sample mean = 20000
standard deviation = 5000
The objective is to choose from the given option about what most closely resembles the relevant box model.
The correct answer is:
It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.
However, if draws are made without replacement, the best estimate of the average amount for the bride will be $20,000
Similarly, the standard error for the sample mean =
the standard error for the sample mean = 125
Answer:
2 + 2 + 2 + 4 + 4 + 4= 20 3 apples and 4 oranges
Step-by-step explanation:
20 - 4 = 16 16 - 4 = 14 - 2 = 12 12 - 4 = 8 8 - 4 = 4 4 - 2 = 2
1 orange 2 oranges 1 apple 3 oranges 4 oranges 2 apples
and 2 - 2 = 0
3 apples
Answer:
step-by-step explanation:
8x+2y=-22
8(0)+2y=-22
2y=-22
and now it is a two step equation
do the same thing to the other one
First simplify the equation of parabola
in the following way:
.
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).
