<u>Answer:</u>
<u>Step-by-step explanation:</u>
We are given the following expression and we are to evaluate it when the value of a is 10 and b is -9:
Substituting the given values in the above expression to get:
Therefore, the simplified form of the given expression that we get after evaluating it when a is 10 and b is -9 is .
Answer:
I'd say it's 0.03
Step-by-step explanation:
0.03 divided by 10 is 0.003 so it's 1/10
Answer:
x ≥ -4
Step-by-step explanation:
There is a closed circle at -4, which means it is equal to
The line goes to the right, which is greater than
x ≥ -4
Reflection over the y-axis:
(x, y) ⇒ (-x, y)
Reflection of that over the line y = x:
(-x, y) ⇒ (y, -x)
Rotation counterclockwise by 270°:
(x, y) ⇒ (y, -x) . . . . . . equivalent to reflection over y, then over y=x.
The appropriate choice is ...
C) Reflecting over the y-axis and then reflecting over the line y = x.
Answer:
Required probability = 7/75.
Step-by-step explanation:
Probability(purple marble) = 7/15 (as there are 7 marbles out of a total of 15.)
Probability( red marble) = 3/15 = 1/5.
So the probability of a purple being drawn followed by a red marble
= 7/15 * 1/5
= 7 /75 (answer).
Note: the 2 probabilities are multiplied because the 2 draws are independent of each other.
