Since there is a total of 17 pens and 2 are removed then there is 15 left. the probability is 5/17 on the first draw and 4/16 (simplified is 1/4) on the second draw.
Answer: Omar can make 14 whole dumplings.
Step-by-step explanation: Make 2 3/4 an improper fraction. To do this, multiply 2 by the denominator, 4. From this, you get 8. Then add 8 to the numerator, which is 3, and you get 11. Keep the denominator and you'll have 11/4.
To divide fractions, you make 3/16 its reciprocal by basically flipping the fraction so that the numerator becomes the denominator and vise versa, making it 16/3. Then multiply 11/4 and 16/3. 11 x 16 is 176; 4 x 3 is 12. The result is 176/12. Simplify by dividing the numerator and denominator by 4. Your resulting answer should be 44/3. Simplify even further by simple division. Your final answer should be 14 2/3. Discard the 2/3 because Omar needs to make whole dumplings. So the answer is 14.
Answer:
Step-by-step explanation:
1) find two factors of c that sum up to -2.
2) 5 and -7 are factors of -35 that sum up to -2.
3) (x+5)(x-7)
4) x+5= 0, x= -5
5) x-7= 0, x= 7
4) the two solutions are -5 and 7.

Answer:
1011011
Step-by-step explanation:
The binary multiplication is pretty much like the decimal one, we have just to remember that in the binary system 1+1 = 10.
First, convert 7 and 13 to binary
7 = 111
13 = 1101
now multiply with the same rules as in decimal
1101x
111
--------------
1101+
1101 +
1101
1111
-------------
1011011
The last row of digits are the carry bits.
So 7*13 = 1101*111(binary) = 1011011 (binary)
