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
4/3th a 100th per distance of both.
Answer:
the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Step-by-step explanation:
The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:
Let us assume the package of chocolate chip cookie be x
And, the package of ginger bread is y
So,
According to the question
6x + 2y = $72
6x + 10y = $216
Now subtract equation 1 from equation 2
-8y = -144
y = $18
And, for x it would be
6x + $36 = $72
x = $6
Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively
Answer:
91
Step-by-step explanation:
(2 + 5)(8 +5)
2 + 5 = 7
8 + 5 = 13
7 * 13 = 91
Answer:
The linear function would be f(x) = 4x - 10
Step-by-step explanation:
In order to find this, we need to take the equation and solve it for y.
y - 2 = 4(x - 3)
y - 2 = 4x - 12
y = 4x - 10
Now we replace the y with f(x) and this is the function.
f(x) = 4x - 10
