Bacteria triples every hour. How much bacteria will there be after two days if they started with 13,000 bacteria.

1 answer:

6 0

13,000 • 3 = 1 hour = 39,000
Now we take the one hours worth 39,000 • 48 (hours in two days) = 1,872,000
Hope this helps!

The sine of the complimentary angle of 28° a. -0.86 c. -0.74 b. 0.88 d. 0.76

In-s [12.5K]

Step One
Find the complimentary angle of 28o Compliments add to 90o.

28 + c = 90
c = 90 - 28
c = 62o

Step two
Find the sin of 62o

sin(62) = 0.8829

So the answer is B

Another way to do it is to take the cos of 28
Cos(28) = 0.8829 which is still B.

Mean absolute deviation around the mean

Mean for set 1 equals: (20+24+40+63+76+89)/6 = 312/6 = 52
Mean for set 2 equals: (41+50+58+62+72+83)/6 = 366/6 = 61

Mean absolute deviation around the mean for set 1 equals:
( |20 - 52| + |24 - 52| + |40 - 52| + |63 - 52| + |76 - 52| + |89 - 52| )/6 = (32 + 28 + 12 + 11 + 24 + 37)/6 = 144/6 = 24

Mean absolute deviation around the mean for set 2 equals:
( |41 - 61| + |50 - 61| + |58 - 61| + |62 - 61| + |72 - 61| + |83 - 61| )/6 = (20 + 11 + 3 + 1 + 11 + 22)/6 = 68/6 = 11,334

A card game has 50 cards. After dealing 7 cards to each player, Tupi has 15 cards left over. Solve the equation 50 7p = 15 to fi

mafiozo [28]

Answer:

50 - 7p = 15....subtract 50 from both sides

-7p = 15 - 50

-7p = - 35...divide both sides by -7

p = -35/-7

p = 5 <=== there are 5 players
