Answer:
1+pi/2, 5/2, square root of 12-1, 2.25. Let me know if this is correct!
Step-by-step explanation:
Step-by-step explanation:
according to the given question
there are 10 bags each have 15kg potatoes so basically, we have 150 kg of poatoes
i want these potatoes to be equally distributed in 50 bags
therefore, mass of potato in 1 bag = total kg's of potatoes÷nuber of bags
mass of potato in 1 bag=150÷50 equals 3 kg
and so, each bag will have mass 3 kg
Answer:
1,3 and 5
Step-by-step explanation:
1) -2(7x + 1) − 5(3x2 + 3x + 2)
= -14x - 2 - 15x^2 - 15x - 10
= -15x^2 - 29x - 12
2) (5x2 − 10x + 8) − (10x2 + 19x + 20)
= 5x^2 - 10x + 8 - 10x^2 - 19x - 20
= -5x^2 -29x - 12
3) (-7x2 − 21x + 13) − (8x2 + 8x + 25)
= -7x^2 - 21x + 13 - 8x^2 - 8x - 25
= -15x^2 - 29x - 12
4) (-19x2 − 4x - 7) + (4x2 + 25x − 5)
= -15x^2 + 21x - 12
5) (-17x2 + 2x − 3) + (2x2 − 31x − 9)
= -15x^2 -29x - 12
6) -2(4x − 15) − 3(5x2 + 7x + 6)
= -8x + 30 - 15x^2 - 21x - 18
= -15x^2 - 29x + 12
Answer:
3/20 or 15%
Step-by-step explanation:
Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.
To find the probability you need to multiply the two probabilities together.
3/5 times 1/4 is 3/20.
So your answer is 3/20 or 15%.
