So now we have….
-(-3.5) + (-12.8) = ?
{the double negative symbols change into a positive}
3.5 + (-12.8) = ?
3.5 - 12.8 = ?
Answer = -9.3
Your answer is a. -9.3
Hope this helps :)
In all cases, the events are independent. That's why we have to multiply the results.
Probability that both numbers are greater than 6 if the same number can be chosen twice.
P = 3 / 9 * 3 / 9 = 1/9 because possible outcomes are the pairs (7,8), (7,9) and (8,9).
Probability that both numbers are less than 7 if the same number can be chosen twice
P = 6 / 9 * 6 / 9 = 4/9
Probability when both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice
P = 3/9 * 2/8 = 1/12, odd numbers less than 6 are 1, 3 and 5. If the same number cannot be chosen depending on these numbers, we'll end up with 2 in possible outcome for the 2nd pair of the probability.
Probability that both numbers are even numbers if the same numbers cannot be chosen twice is
P = 4/9 * 3/9 = 4/27. The same logic is possible in this case, as well
The domain is all real numbers
The range is y<= 4
Choice C
Answer:
Step-by-step explanation:
Standard form of a sideways parabola:
Given equation:
Add x to both sides:
--------------------------------------------------------------------------------------------
<u>Standard form of circle equation</u>
(where (a,b) is the center and r is the radius)
Given equation:
Group like terms:
Divide by 2:
Factor by completing the square for each variable:
Rearrange into standard form:
Therefore, the circle has a center at (4.5, 2.5) and a radius of √23
Answer:
-16
Step-by-step explanation:
x/-2 = 8
cross multiply.
-2(-2) = 0 (because you're cross multiplying)
8(-2) = -16
x= -16
