Answer:
2/15.
Step-by-step explanation:
The prime numbers in the first 10 numbers are: 2, 3, 5, 7 . That is a total of 4.
Prob( first number drawn is prime) = 4/10 = 2/5.
Prob( second number drawn is prime) = 3/9 = 1/3.
Required probability is 2/5 * 1/3
= 2/15.
Remember to use PEMDAS when solving.
= 7 + (5 – 9)2 + 3(16 ÷ 8)
= 7 + (-4)2 + 3(2)
= 7 + (-8) + 6
= -1 + 6
= 5
Best of Luck!

Answer:
It is B. hyperbola, 45 degrees.
SteIt is p-by-step explanation:
If we rotate the standard form x^2 - y^2 = 1 through 45 degrees we get xy = 1/2.
xy = -2.5 comes from x^2 - y^2 = -5 being rotated 45 degrees.
