Answer:
[tex]P(Same)=\frac{61}{190}[/tex]
Step-by-step explanation:
Given
[tex]Red = 5[/tex]
[tex]White = 6[/tex]
[tex]Black = 9[/tex]
Required
The probability of selecting 2 same colors when the first is not replaced
The total number of ball is:
[tex]Total = 5 + 6 + 9[/tex]
[tex]Total = 20[/tex]
This is calculated as:
[tex]P(Same)=P(Red\ and\ Red) + P(White\ and\ White) + P(Black\ and\ Black)[/tex]
So, we have:
[tex]P(Same)=\frac{n(Red)}{Total} * \frac{n(Red) - 1}{Total - 1} + \frac{n(White)}{Total} * \frac{n(White) - 1}{Total - 1} + \frac{n(Black)}{Total} * \frac{n(Black) - 1}{Total - 1}[/tex]
Note that: 1 is subtracted because it is a probability without replacement
[tex]P(Same)=\frac{5}{20} * \frac{5 - 1}{20- 1} + \frac{6}{20} * \frac{6 - 1}{20- 1} + \frac{9}{20} * \frac{9- 1}{20- 1}[/tex]
[tex]P(Same)=\frac{5}{20} * \frac{4}{19} + \frac{6}{20} * \frac{5}{19} + \frac{9}{20} * \frac{8}{19}[/tex]
[tex]P(Same)=\frac{20}{380} + \frac{30}{380} + \frac{72}{380}[/tex]
[tex]P(Same)=\frac{20+30+72}{380}[/tex]
[tex]P(Same)=\frac{122}{380}[/tex]
[tex]P(Same)=\frac{61}{190}[/tex]

Q1 (Describe the two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system)Q2(Describe how proteins are made packaged and transported within the cell) plz help fast
Step-by-step explanation:
Ans 1
Two eukaryotic animal cell organelles that have roles similar to the organs of the human digestive system are lysosome and mitochondria. ... Mitochondria is like the small intestine, it is responsible for converting the food we eat into nutrients and minerals needed for the cell
Ans2
The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell. ... Proteins must make their way through the stack of intervening cisternae and along the way become modified and packaged for transport to various locations within the cell (Figure 1).

Given the following situation, determine if the data is rank data. A NFL Stadium manager wants to compare the Customer Satisfaction levels of two different stadium locations. He randomly selects 30 customers from Stadium A and Stadium B, and he compares the results. The Customer Satisfaction Survey measures responses as "Highly Satisfied", "Satisfied", "Neither", "Unsatisfied", and "Highly Unsatisfied." Is this rank data? Group of answer choices not rank data rank data
Answer:
Rank data
Step-by-step explanation:
Ranked data scale is one in which the ordering or levels in the scaling format follows or depicts a certain degree of importance or hierarchy. They are usually used in ordinal scaling method. In the scenario above, the ranking follows a defined order with the highest level of satisfaction which a customer can report being Highly Satisfied" followed by "Satisfied" then "Neither" (meaning that customer is neither satisfied nor unsatisfied) the least level of satisfaction which a customer could report is being "Highly Unsatisfied." which is worse than being "Unsatisfied".

Answer: 13 is the first one and the second one is 15
Step-by-step explanation:
The double number line shows how far a hummingbird can fly in 1 second.
Answer:
1st box-1
2nd box-3
3rd box-130
Step-by-step explanation:
On the number line, 13 metres is in line with 1 second. So, that means the hummingbird flies 13m/s.
Then to work out the second box, for how much time it takes to travel 39 metres, you would have to do 39÷13=3. This means that in 3 seconds, the hummingbird flies 39 metres in 3 seconds.
To work out how many metres the hummingbird flies in 10 seconds, you would have to do 13×10=130. The reason why you times 13 by 10 is because the hummingbird does 13 metres in 1 second, but we want 10 seconds, so we times it.
Hope this helps :)

(Constructed Response) Determine whether the binomial, 9x² - 49, is a difference of
two squares. If so, factor it. If not, explain why.
Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)
=============================================================
Explanation:
We can write the 9x^2 as (3x)^2 since
(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2
The 49 can be written as 7^2 because 7^2 = 7*7 = 49.
This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.
The difference of squares factoring rule is
a^2 - b^2 = (a-b)(a+b)
which we have a = 3x and b = 7 in this case
So,
a^2 - b^2 = (a-b)(a+b)
(3x)^2 - 7^2 = (3x-7)(3x+7)
9x^2 - 49 = (3x-7)(3x+7)
Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.

Answer:
The angle measures of quadrilateral P'R'S'T are equal to the corresponding angle measures of quadrilateral PRST
Step-by-step explanation:
The transformation rule (x,y) ----> (x + 4 , y + 9 ) is an example of translation.
Translation is moving the points around.
During a translation the only thing that changes is the location of the points.
Everything else stays the same therefore the corresponding angles will be congruent.

Enter a phrase for the expression
Answer:
The quotient of x and 11.
Step-by-step explanation:
Given:
[tex] \frac{x}{11} [/tex]
Required:
Write the expression in words
Solution:
In the expression given, we have the numerator which is the dividend (x), and the denominator which is the divisor (8).
So, we are dividing x into 8 parts.
A quotient is the result you get when you divide the dividend by the divisor.
✅In describing the expression in words, we would use the following phrase:
The quotient of x and 11.
The dividend is mentioned first before the dividend.
