Ametallurgist is designing an experiment to determine the effect of flux, base metal, and energy input on the hardness of a weld. she wants to study four different fluxes, two different base metals, and three different amounts of energy input. if each run of the experiment involves a choice of one flux, one base metal, and one amount of energy input, how many different runs are possible?

24

Step-by-step explanation:

Given : A metallurgist wants to study four different fluxes, two different base metals, and three different amounts of energy input.

i.e. 4 different choices for fluxes.

2 different choices for base metals.

3 different choices for amounts of energy input.

If each run of the experiment involves a choice of one flux, one base metal, and one amount of energy input.

Then , the number of runs are possible :-

Hence, there are 24 different runs are possible .

the answer is 31.27mph

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
