Answer:
a) The car will be worth $8000 after 2.9 years.
b) The car will be worth $6000 after 4.2 years.
c) The car will be worth $1000 after 12.7 years.
Step-by-step explanation:
The value of the car after t years is given by:
According to the model, when will the car be worth V(t)?
We have to find t for the given value of V(t). So
(a) $8000
V(t) = 8000
The car will be worth $8000 after 2.9 years.
(b) $6000
V(t) = 6000
The car will be worth $6000 after 4.2 years.
(c) $1000
V(t) = 1000
The car will be worth $1000 after 12.7 years.
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98
<h3>What is a sample size?</h3>
The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.
Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.
For a population mean of 20.15 and a standard deviation of 3.7
68% are within μ ± σ/√n,
hence,
68% = 20.15 ± 3.7/√20 = (19.32, 20.98)
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.

n/4 because all it wants is a number which is expressed by n divided by 4
Answer:
4(2x+1)
Step-by-step explanation:
Add the expressions 3x-2 and 5x+6
which is 8x+4
since every one of the answers are in distributive form, just take the GCF (Greatest Common Factor) out of both
