2456 / 3 = 818
Rounded = 800
Answer 800 Pennies in each box.
According to the given equation, to solve the equation we have to use the square roots:
Answer: (1.375, 18.625 )
Step-by-step explanation:
The confidence interval for population mean is given by :-
(1)
, where = sample mean
t* = critical value.
SE = standard error
As per given , we have
n= 21
Degree of freedom : df = n-1=21-1=20
Significance level :
Standard error : SE= 5
The critical t-value for confidence interval is a two-tailed value with respect to the given degree of freedom i.e. .
Using student's t-distribution table ,
The 90% confidence interval will be :
[by formula in (1)]
Hence, the limits of the confidence interval=(1.375, 18.625 )

Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1
