Answer:

Step-by-step explanation:

Given that:

Space left on flash drive = 3/71 * 10^7 bytes = 0.0422535 * 10^7 = 422535.21 bytes

Size of each file = 8.2 * 10^4 bytes = 82000 bytes

Number of files that can be copied :

(422535.21) / (82000)

= 5.1528684

Number of files that can be copied = 5 files

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?

BaLLatris [955]

Answer:

19 dimes and 9 nickels

Step-by-step explanation:

Model the situation using two equations, then solve the system.

let n be number of nickels and d be number of dimes.

n + d = 28 <= This equation is about the number of coins.

0.05n + 0.10d = 2.35 <=This equation is about the worth in dollars.

Rearrange n + d = 28.

n = 28 - d

Now we can substitute this equation into the other one.

Sub n =28-d at the "d" variable for the equation 0.05n + 0.10d = 2.35

0.05n + 0.10d = 2.35

Now there is only one variable.

0.05(28 - d) + 0.10d = 2.35 <=distribute this

0.05(28 - d) + 0.10d = 2.35

1.4 - 0.05d + 0.10d = 2.35 <=combine like terms

1.4 + 0.05d = 2.35 <= begin to isolate d

0.05d = 2.35 - 1.4

0.05d = 0.95

d = 0.95/0.05

d = 19

Now that we know d=19, we can substitute it into any equation.

Choose the equation n + d = 28 because the numbers are easier.

n + d = 28

n + 19 = 28 <=isolate n

n = 28 - 19

n = 9

Since n=9 and d=19, Kay has 9 nickels and 19 dimes.

The given diagram is a scatter plot in which temperature is plotted against number of visitors.

As the number of visitors is rising with the rise in temperature, its a positive correlation.

As joining the dots is going to give a web of line segments, it is not going to be helpful to understand the trends.

The best way to understand the trends is to make the line of best Fit in such a way that the number of dots on either side are approximately the same.

I have attached the figure for your reference of the line of best fit.
