(1.2 x 10-4) + (2.4 x 10-3)

Mathematics
1 answer:
ryzh [129]3 years ago
6 0

Answer:

29

Step-by-step explanation:

(1.2 x 10-4) + (2.4 x 10-3)

Simplify

1.2 x 10- 4 = 8

2.4 x 10- 3 = 21

Add both sums to get 29!

SCIENTIFIC NOTATION

2.9 x 10 to the 1st power

Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better

The mathematics department of a college has 10 male​ professors, 12 female​ professors, 12 male teaching​ assistants, and 15 fem
lana [24]

We need the total count of persons = 10+12+12+15 = 49 persons

We need the count of the target group, female or teaching assistants

= (10+12) professors + 12 male teaching assistants

= 22+12

= 34 persons

Assuming equal probability of choosing anyone from the 30 persons, the

probability of choosing a professor or a male

= 34/49

(For probability calculations, try to keep a fraction for as long as you can, because fractions are exact. Decimal are frequently approximate, for example in this case, 34/49=0.693877551020...... = 0.694 approximately)

Three people play a game on each spinner in the previos problem.
arlik [135]

Answer:

Step-by-step explanation:

All other things being equal, spinner A is fine. It is a fair spinner.

Spinner B is not fair. Players 1 and 3 have only 1 number each. Player 2 on the other hand, has 2 numbers that work for him. If player 2 puts in two dollars and players 1 and 3 one dollar each, that should even up the odds. Now you want it just to be fair. So I think player 2 has to put up 2 dollars and players 1 and 3 each put up one. The pot is 4 dollars each time it is played.

Spinner 3 is not fair either. Player one has 2 chances. Player 2 has 3 chances and player 3 has but one chance. There are 6 chances in all. Player 1 should put up 2 dollars to play player 1 should put up 3 dollars and player 1 should put up 1 dollar.
