can someone please help me with this? PLEASE I'm so confused.
==================================================
Explanation:
Let's say we had the slots A,B,C,D,E,F. Each slot represents where a flower would go.
For slot A, we have 15 different flowers to pick from.
Then slot B has 15-1 = 14 choices
C has 15-2 = 13 choices
and so on. We count our way down until we fill up slot F.
The count down looks like this: 15, 14, 13, 12, 11, 10
Multiply out those values: 15*14*13*12*11*10 = 3,603,600
If order mattered, then this represents the number of ways to select 6 flowers from a pool of 15 total.
However, order does not matter in this case. All that matters is the group overall.
For any group of 6 items, we have 6! = 6*5*4*3*2*1 = 720 different arrangements. That means the value 3,603,600 is too large exactly by a factor of 720.
We divide by 720 to get to (3,603,600)/720 = 5005 which is the final answer
It's the number of combinations where we select 6 from a pool of 15.
-------------------------------
As you can guess, you could use the nCr combination formula as an alternative route. Plug in n = 15 and r = 6 like so
[tex]_n C _r = \frac{n!}{r!*(n-r)!}\\\\_{15} C _{6} = \frac{15!}{6!*(15-6)!}\\\\_{15} C _{6} = \frac{15!}{6!*9!}\\\\_{15} C _{6} = \frac{15*14*13*12*11*10*9!}{6!*9!}\\\\_{15} C _{6} = \frac{15*14*13*12*11*10}{6!}\\\\_{15} C _{6} = \frac{15*14*13*12*11*10}{6*5*4*3*2*1}\\\\_{15} C _{6} = \frac{3,603,600}{720}\\\\_{15} C _{6} = 5005\\\\[/tex]
In the third to last step, notice how we have the 15*14*13*12*11*10 up top and 6*5*4*3*2*1 down below.
This value 5005 can be found in Pascal's Triangle. Look in the row that has 1, 15, ... and count out 7 spaces from the left. You should arrive at 5005. However, you'll need a fairly large Pascal's Triangle to use this method.
Given:
Total number of flower cuts = 15 different flowers
Number of flowers Jeanine Baker wants to use = 6 flowers
To find:
Total number of ways 6 flowers can be chosen
Steps:
In this question, we need to find the total number of outcomes of choosing 6 random flowers from a total of 15 flowers
Let's give each flowers a letter, so there will be A, B, C, D, E, F, G, H, I, J, K, L, M, N and O.
Now let's find all the outcomes
Outcomes= ABCDEF, ABCDEG, ABCDEH, ABCDEI, ABCDEJ, ABCDEK, ABCDEL, ABCDEM, ABCDEN, ABCDEO.....
This method will take a lot of time so, i am going to use the formula
[tex]No.outcomes = \frac{n!}{r!(n-r)!}[/tex]
Here n = total number of items, and r = number of items chosen
Also the '!' means factorial, or the product of all positive numbers less then or equal to the number, so n! = n * (n-1) * (n-2) ..... * 1
So, now substituting the formula
[tex]No.outcomes = \frac{15!}{6! * (n-r)!}[/tex]
[tex]No.outcomes=\frac{15!}{6! * 9!}[/tex]
[tex]No.outcomes = \frac{15*14*13*12*11*10*9*8*7*6*5*4*3*2*1}{6*5*4*3*2*1*9*8*7*6*5*4*3*2*1}[/tex]
[tex]No.outcomes=\frac{15*14*13*12*11*10}{6*5*4*3*2*1}[/tex] (cutting same numbers)
[tex]No.outcomes = \frac{7*13*3*11*10}{6}[/tex] (simplifying)
[tex]No.outcomes = \frac{30030}{6}[/tex]
[tex]No.outcomes=5005[/tex]
Therefore, the total number of ways the 6 flowers can be chosen is 5005 ways

2x-54 and x + 22 are vertical angles and equal each other. Set the two equations equal to each other and solve for x.
2x -54 = x + 22
Add 54 to both sides:
2x = x + 76
Subtract 1x from each side:
X = 76
The answer is x = 76
The area of the triangle below is 4.5 square inches. What is the length of the base?
Answer:
Can you please send the length of the height if possible.
Step-by-step explanation:
Also the the formula to solve this is the exact opposite of Area= base times height divided by 2.
first step you need to do is multiply 4.5 by 2 to get 9. then you have to divide 9 by the height. Then you will get the value of the height. Hope you understood!

The girls in Lana’s troop set a goal to sell 1,000 boxes of cookies this year. There are 13 girls in the troop. At least how many boxes of cookies should each girl sell to reach their goal?
Answer:
77 boxes
Step-by-step explanation:
Step 1:
Lana's troop must sell 1000 boxes of cookies, but there are 13 girls in total. Supposing that each girl will sell an equal amount of boxes, we can simply divide:
[tex]1000[/tex]÷[tex]13\approx76.92[/tex] boxes.
Step 2:
However, it would seem unlikely that the girls would decide to sell fractions of a box of cookies. We should round...up or down?
If we round down, each girl will sell 76 boxes of cookies. Hmm... then they would'nt be able to sell a total of 1000 boxes of cookies! We need to round up.
Therefore, each girl should sell at least [tex]\fbox{77}[/tex] boxes.

What is 3,700,000 in scientific notation??
=========================================================
Explanation:
Place a decimal point between the first two digits 3 and 7.
Now ask yourself how you can go from 3.7 back to the original value. Notice we can move the decimal point 6 spots to the right to go from 3.7 back to 3,700,000
Therefore, the exponent over the 10 is 6. The exponent is positive to mean we move the decimal point to the right. If we had a negative exponent, then we'd move left.
You can use a calculator to confirm that 3.7 * 10^6 = 3,700,000
--------------
Side notes:
3,700,000 = 3 million, 7 hundred thousand
3,700,000 = 3.7 million

Find the measure Of K
Answer:
K = 10
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin K = 11 / 61
Taking the inverse sin of each side
sin ^-1 ( sin K) = sin ^-1 (11/61)
K =10.38885782

plz help ASAP... I'll mark you as the brainliest!
Answer:
(a) 495, (b) 210
Step-by-step explanation:
Total number of persons = 12
number of openings = 8
number of women = 7
number of men = 12 - 7 = 5
(a) Number of ways to select the 8 persons
[tex]C_{8}^{12}\textrm{}\\\\= \frac{12!}{8!\times 4!}\\\\=495[/tex]
(b) Three are men
So, 3 men and 5 women
The number of ways are

The equivalent expression for the given expression is h³.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is h⁶/h³.
h⁶ can be written as h³×h³
= h³×h³/h³
= h³
Therefore, the equivalent expression is h³.
