Answer:
$66,092.50
Step-by-step explanation:
In 1988, the car cost $17,000
Annual inflation over this period was 3.54% from 1988 to 2017
After adjusted for inflation, $17,000.00 in 1978 is equal to $66,092.50 in 2017
Therefore, the cost of that car in 2017 is closest to $66,092.50
Answer: see below
<u>Step-by-step explanation:</u>
12) 2(x + 4) = 8
<u> ÷2 </u> <u> ÷2 </u>
x + 4 = 4
<u> -4 </u> <u> -4 </u>
14) 4w - 2(1 - w) = -38
4w -2 + 2w = -38
(4w + 2w) - 2 = -38
6w - 2 = -38
<u> +2 </u> <u> +2 </u>
6w = -36
<u> ÷6 </u> <u> ÷6 </u>
16) 10(1 - 2y) = -5(2y - 1)
10 - 20y = -10y + 5
<u> +20y </u> <u>+20y </u>
10 = 10y + 5
<u> -5 </u> <u> -5 </u>
5 = 10y
<u> ÷10</u> <u> ÷10 </u>
Answer:
The probability that the sample mean would differ from the population mean by more than 2.6 mm is 0.0043.
Step-by-step explanation:
According to the Central Limit Theorem if we have a population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample means will be approximately normally distributed.
Then, the mean of the distribution of sample mean is given by,
And the standard deviation of the distribution of sample mean is given by,
The information provided is:
<em>μ</em> = 144 mm
<em>σ</em> = 7 mm
<em>n</em> = 50.
Since <em>n</em> = 50 > 30, the Central limit theorem can be applied to approximate the sampling distribution of sample mean.
Compute the probability that the sample mean would differ from the population mean by more than 2.6 mm as follows:
*Use a <em>z</em>-table for the probability.
Thus, the probability that the sample mean would differ from the population mean by more than 2.6 mm is 0.0043.
If the pictograph is drawn wrong or information could be left out of it. Things could be not drawn to scale. All of this could be misleading. At least this is what I think is the right answer I hope this helps!
Answer:
No.
Step-by-step explanation:
To find the y value, one must replace x value, meaning that it's a multi step problem and it's not direct because y=exact value is not given
