A quality control inspector examined 150 light bulbs and found 8 of them to be defective. At this rate how many degective light bulbs will there be in a lot of 2000?

106

Step-by-step explanation:

For every 150 light bulbs, 8 are defective

The defective rate can be written as;

8/150

= 4/75

Now, to find the number of defective light bulbs in a lot of 2000, we simply multiply the defective rate by this amount

This gives;

4/75 * 2000

= 106.6

This is approximately 106 light bulbs because a light bulb is either defective or not so, we need to have a whole number.

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
