Answer:
Price is decreased by $3,312
And, the price of the next model is $44,688
Step-by-step explanation:
The computation is shown below:
Given that the current model cost is $48,000
And, there is 6.9% lower than the current model
So, the price would decrease in dollars is
= $48,000 × 6.9%
= $3,312
The price of the next model is
= $48,000 - $3,312
= $44,688
This is empirical probability because it is your own experiment and it is on how YOU measured this probability. However, experimental probability is based on statistics.
Hope this helps!
Answer:
False
Step-by-step explanation:
given that a race car driver tested his car for time from 0 to 60 mph, and in 20 tests obtained an average of 4.85 seconds with a standard deviation of 1.47 seconds.
Sample size n = 20
since population standard deviation is not known, we can use t critical value for finding out the confidence interval
df=19
t critical = 2.045
Margin of error = 
conidence interval = Mean±Margin of error
= 
The given confidence interval is (4.52, 5.18)
Hence the statement is false.
Answer:
c = 289
Step-by-step explanation:
Given
x² + 34x
To complete the square
add ( half the coefficient of the x- term )² to x² + 34x
= x² + 2(17)x + 17²
= x² + 34x + 289 ( with c = 289 )
= (x + 17)² ← perfect square
You earn $15 per lawn. 1 lawn would be $15. 15(1) is 15.
7 lawns would be 15(7), which is 105.
