Answer:

Megavolt used a Systematic sampling method.

Step-by-step explanation:

From the information given:

For every 100th evil light bulbs tested, he starts with the 42nd. This implies that;

The first bulb tested is the 142nd bulb, the second bulb tested is the 242nd...

The sequence is as follows:

142nd, 242nd, 342nd, 442nd, 542nd, 642nd .... etc

From the starting point of manufacturing the evil light bulb, the sequence is derived from sampling where each nth unit is known to be a sample, and this is only feasible in systematic sampling.

Find two numbers that have a sum of -2 and a product of -48 (please show work if possible)​
andreev551 [17]

Answer: -8 and 6

Step-by-step explanation:

factors of 48: 1,2,4,6,8,12,24,48

1 x 48

2 x 24

4 x 12

6 x 8

for a negative product, one of the factors must be negative and the other positive.

for two number to have a sum of -2, the greater number must be the negative number, and both numbers should have be two values apart (ex. 6 and 8, 3 and 5, 12 and 14, etc.). In this case, 8 would have to be negative whereas 6 will be left positive.

and then we check:

-8 x 6 = 48

-8 + 6 = -2
