Multiply 30 by 80% - or 0.8.
The resulting number is how many questions he got right.
Subtract that number from the total of 30, and you'll know how many he got wrong.
You can also do it as a fraction - 80% out of 100% is 80/100, or 4/5. So he got 4/5 right and 1/5 wrong.
30 multiplied by 1/5 is the same as 30 divided by 5. So 30 divided by 5 will be how many questions he got wrong.

The manager of a warehouse would like to know how many errors are made when a product’s serial number is read by a bar-code read
maw [93]
<span>In order to determine the total number of errors that were made by the bar code scanner, we first have to calculate how many total scans were made. Because there were six items scanned 1,000 times each, there were 6,000 total scans made. Next, we have to add up the total number of errors made by each item (36+14+21+39+11+2). As a result, there were a total of 123 errors made during the 6,000 scans.</span>

Describe how to transform the graph of f(x) = x2 to obtain the graph of the related function g(x).
gavmur [86]

Answer:

7.

g(x) = f(x + 1) =

(x + 1)² = x² + 2x + 1

as the original function, but the turnaround is now (still at x = 0) at y = 1 instead of y = 0.

and the graph is "narrower". for x = 1 and x = -1, y = 4. for x = 2 and x = -2, y = 9

8.

g(x) = f(x) - 2

= x² - 2

it is exactly the same graph, just 2 units down in y direction (the turnaround is at x = 0. y = -2).

9.

the right answer is D

Step-by-step explanation:

9.

the y values of +x values now become the same values for the -x values. and vice versa.
