Answer:
$15.5
Step-by-step explanation:
58+4=62 62divided by4=15.5 :) Have a nice day
The formula would be
A=p (1-r)^t
P 3400
R 0.02
Since it decreases every 20 years
From 2000 to 2040 it decreases 2 times so
T 2
A=3,400×(1−0.02)^(2)
A=3,265
It's c
8% as a decimal is .08 multiplied by 50 is 4 which is the answer.
Answer: The campers will be 
from their car after 12 hours.
Step-by-step explanation:
<h3>
The missing graph is attached.</h3>
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" the y-intercept.
We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:
Choosing the points (0,4) and (2,10), we get:
We can susbstitute the point (0,4) and the slope into and solve for "b":
Then, the equation of this line is:
Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:
Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute 
into the equation and evaluate. Then we get:
Answer:
Yes, there is significant evidence to support the claim that sample standard deviation is higher than that claimed by the manufacturer
Step-by-step explanation:
Sample standard deviation, s = 3.2
Population standard deviation, σ = 2
Defining the Null and alternative hypothesis :
H0 : σ = 2
H1 : σ > 2
The test statistic :
Use the Relation :.
[(n - 1)*s²] ÷ σ²
[(10 - 1) * 3.2²] ÷ 2²
(9 * 10.24) ÷ 4
92.16 ÷ 4
= 23.04
We obtain the Pvalue for the distribution :
Using the Pvalue from Chisquare distribution calculator :
Pvalue(Chisquare score, df)
df = n - 1 = 10 - 1 = 9
Pvalue(23.04, 9) = 0.006107
Decision :
If Pvalue is < α ; Reject H0 ; α = 0.05
0.006107 < 0.05 ; We reject H0
