26000 - 32000 = 32000 - 38000 = -6000
Since the difference is common this is a linear function

32300/38000 = 27465/32300 = 0.85
Since the ratio is common this is an exponential function

V(x) = 38000 - 6000x

V(x) = 38000*0.85ˣ

Find V(6) for both cars and compare

V(6) = 38000 - 6*6000 = 2000

V(6) = 38000*0.85⁶ = 14331.68

As we see the difference is significant and car 2 has much greater value

0.48 = log x solve for x

marissa [1.9K]

Answer: x≈3

Step-by-step explanation:

0.48 = log x , this could also be written as :

$log_{10}$ x = 0.48 , that is

x = $10^{0.48}$

x = 3.01995172

x≈ 3

The mean of the values in a data set is c. If each of the values in the data set were multiplied by 6, what would be the mean of

oksian1 [2.3K]

Answer:

Mean of the data would be 6c

Step-by-step explanation:

<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.

In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c

Let us consider that original values in the data set are x, y and z. Their mean would be:

$Mean=\frac{x+y+z}{3}$

If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:

$Mean=\frac{6x+6y+6z}{3}\\Mean=\frac{6(x+y+z)}{3}\\Mean=6\times\frac{x+y+z}{3}\\Mean=6c$

We can see from above that the new mean is 6 multiplied to the original mean.

Therefore, the answer to this question is 6c.

Question 2:

Mashutka [201]

He rode his bike for 45 min a day for 6 days that means he rode 270 min in total. And the total he worked out was 360 min that week.

360 - 270 = 90

Now you divide by 6 because of the days he worked out.

90 divided by 6 = 15.
