Answer:
-460
Step-by-step explanation:
I multiply by splitting the numbers into digits. So for the 90, in my head I did 5 × 90, which is 450. Then I did 2 × 5, this is 10. Now I added those up to make 460. Considering the 92 is negative, the answer will also be negative.
THE SURFACE AREA IS 3220CM^2
Answer:
a) 9 / 200
b) 13 / 100
Step-by-step explanation:
a) The two events are independent because they do not depend each other since the marbles are replaced. To find the total probability of two independent events, you multiply the probability of each event together.
Probability is represented by the amount of desirable outcomes over the total number of outcomes. The total would be the number of marbles, which is: 8 + 4 + 5 + 2 + 1 = 20 outcomes. The number of orange marbles is 2, so the outcomes where you do not pick orange are 20 - 2 or 18 outcomes. The probability of not picking an orange marble would be 18 / 20 or 9 / 10 (using the formula for probability).
There is one outcome where we can pick a blue marble, so the probability of picking a blue marble is 1 / 20. Now, we need to multiply the probabilities for each event: 1 / 20 * 9 / 10 = 9 / 200
b)There are 5 green marbles and 8 red marbles, so the the total outcomes where you pick green or red is 13. We put that over our total to get 13 / 20.
There are 4 purple marbles, so the probability of picking purple is 4 / 20 or 1 / 5. Now we multiply the two probabilities to get the total probability: 1 / 5 * 13 / 20 = 13 / 100
Use 2 points on the line to find the slope.
Slope = change in y / change in x
The two points used: (-2,5) and ( 1,-10)
slope = (-10 -5) /(1- -2) = -15/3 = -5
the y intercept is where the line is at in the y direction when it crosses the x axis at 0.
the y intercept is -5
The equation is y = -5x -5
Answer:
1.) Drawing a king or a queen.
Step-by-step explanation:
1.) Drawing a king or a queen.
You cannot get a king and a queen at the same time= mutually exclusive
2.) Drawing a club or a black card.
King of clubs is both a club and a black card
3.) Drawing a king or a heart.
king of hearts is both a heart and a king
4.) Drawing a face card or a heart
queen of hearts is a heart and a face card
