Answer:
15 is the next term in the sequence.
Answer:
Step-by-step explanation:
To find the probablility, add all of the possibilities. Then, divide the outcome by the total possibilities.
x+3x+5x+4x=13x
x/13x=1/13.
So, the probabilit is 1/13.
Answer:
33.04% probability that exactly five of them are black
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the buttons are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
Five black buttons, from a set of 10
Four brown buttons, from a set of 6.
Total outcomes:
Nine buttons, from a set of 16.
Probability:
33.04% probability that exactly five of them are black
2y+5
I would guess that you would jut simplify by just adding the two y's and adding positive 7 and negative 2.
Hope this helped!
Answer:
7.25 (h) + 105 ≥ 329.75 represents all the possible values of h.
Step-by-step explanation:
Sara's earning per hour = $7.25
Amount earned in tips = $105
Total amount she earned = $329.75
h : Minimum number of hours Sara could worked
So, according to the question:
Total amount earned by Sara in h hours =
Amount each hour x h working hours + Tip
= 7.25 (h) + 105
And the earned amount id more than on equal to $329.75
⇒7.25 (h) + 105 ≥ 329.75 is the required inequality which represenst all possible values of h.
