Jason, Lewis, and Nora will be placed in a line along with 7 other people.
What is the probability that they will be next to each other in any order?
Give percentage
Answer:
[tex]Pr = 6.67\%[/tex]
Step-by-step explanation:
Given
[tex]n = 10[/tex] i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
[tex]Total = n![/tex]
[tex]Total = 10![/tex]
If the three are to be next to each other,
First, we arrange the three
[tex]r_1 = 3![/tex]
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
[tex]r_2 =8![/tex]
So, the total arrangement, when they have to be next to one another is:
[tex]r = r_1 * r_2[/tex]
[tex]r = 3! * 8![/tex]
The probability is:
[tex]Pr = \frac{r}{n}[/tex]
[tex]Pr = \frac{3! * 8!}{10!}[/tex]
Expand
[tex]Pr = \frac{3*2*1 * 8!}{10*9*8!}[/tex]
[tex]Pr = \frac{3*2*1}{10*9}[/tex]
[tex]Pr = \frac{6}{90}[/tex]
[tex]Pr = 0.0667[/tex]
Express as percentage
[tex]Pr = 0.0667 * 100\%[/tex]
[tex]Pr = 6.67\%[/tex]

help me with this math question please I'm giving away brainliests
Answer:
Step-by-step explanation:
Given function in the question is,
[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]
[tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]
[tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]
Given function is not defined at x = -2
At x = -2,
[tex]f(-2)=\frac{1}{2}(2)[/tex]
[tex]=1[/tex]
Therefore, there is a hole in the graph at (-2, 1).
Graph of the function 'f' will be a straight line with a hole at (-2, 1).
Horizontal asymptote → None
Vertical asymptote → None
x-intercept → No x-intercept [Line passes through origin (0,0)]
y-intercept → No y-intercept [Line passes through origin (0,0)]
Hole → (-2, 1)
Andrew sold 60 baseball cards to a friend . This was 80% of Andrews total baseball card collection. How many total baseball cards where in Andrews collection ?
Answer:
75
Step-by-step explanation:
We know that 80% of Andrew's (former) baseball card collection is 60. Thus, We divide 60 by 80% (equal to 0.8) to obtain [tex]\frac{60}{0.8}=75[/tex].
Answer:
In total there were 75 cards in Andrews collection.
Step-by-step explanation:
We know that 60 is 80% of the total amount of cards Andrew has. Therefore, all we have to do to find the total number of baseball cards is to divide 60 by 80 to find 1% and then multiply the result by 100 to get 100% (the total amount of cards). And so we get...
60 / 80 x 100 = 60 / 0.8 = 75

At a surf shop in Malibu, California, a used blue surfboard is on sale for $100. According to the salesperson, the new price represents a 20% discount from the original price. What did it sell for originally?
Answer:
$125
Step-by-step explanation:
if there was a discount of 20%, the sales price is 100 - 20 = 80% of the original price
let a = original price
this equation can be used to represent the question
a x 0.8 = 100 ]]divide both sides by 0.8
a = 100 / 0.8 = 125

Answer:
Table 1(red)
Step-by-step explanation:
A proportional relationship will have a constant of proportionality between y and x all through the data given.
Constant of proportionality, k = y/x
Table 1 (red):
y/x = 5/1 = 10/2 = 20/4 = 5
k = 5 all through, therefore, this table show a proportional relationship between x and y
Table 2 (blue):
y/x = 1/6 ≠2/9 ≠ 4/15
This doesn't have a constant of proportionality, k, that is the same all through in the given table of values. Therefore, it doesn't show any proportional relationship between x and y
