Answer:
P(9,7) = 181440
Step-by-step explanation:
The roles are distinct so order matters. So we must use the permutation formula.
P(n,r)=n!/(n−r)!
P(9,7) = 9! / 2! = 9*8*7*6*5*4*3 = 181440
What is the equation of the line that passes through the point (−1,−1) and has a slope of −6?
Answer: y= -6x -7
Step-by-step explanation:
Point slope formula : y-y1=m(x-x1)
y- (-1)=-6(x- (-1))
y+1= -6(x+1)
y+1= -6x-6
y+1-1=-6x-6-1
y=-6x-7
Standard from 6x+y=7

I need help! It’s angles !
Answer:
Angle 1= 106° and Angle 2=74°
Step-by-step explanation:
Angle 2 is 74° because lines a and b are parallel, and since there is a transversal, the 74° angle and angle 2 are corresponding angles.
Angles 1 and angle 2 are supplementary, so you would just do 180° - 74° and you get 106°
Lewis wants to play several games of paintball with his friends. At the park, it costs $10.90 for admission and paintballs, and $6.18 for each game he plays. Which of the following equations could be used to determine Lewis's total cost for several games of paintball? (Let x represent the number of games Lewis plays and y represent his total cost.) A. y = $10.90x + $6.18 B. y = $6.18x C. y = $6.18x + $10.90 D. $10.90y = $6.18x
Answer:
C. y= 6.18x + 10.9
Step-by-step explanation:
Every game that he plays (x) costs 6.18, for example, if he plays 3 games it would be 6.18 times 3 (games)
Now you have to add your admission, 10.9
To enter he needs to pay the admission ( 10.9 ) and also each game ( x ) he plays ( 6.18 )

ollie is making salad dressing.He mixes 1 part vinegar to 2 parts oil.Ollie makes 450mls of salad dressing.how much oul does he use
Answer:
let one part =x
part of vinegar= x
part of oil =2x
part of oil +part of vinegar = 450ml
2x+x=450
3x=450
x=450/3
x=150
part of vinegar=150ml
part of oil= 300ml
The amount of oil used by Ollie is 300ml.
What is linear equation in one variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
Suppose the vinegar is x ml.
So, the oil is 2x ml.
Ollie makes 450mls of salad dressing.
⇒ 2x + x = 450
Solve the above linear equation for x.
⇒ 3x = 450
⇒ x = 150ml
Therefore, amount of oil she used = 2 × 150ml = 300ml.
Hence, the amount of oil used by Ollie is 300ml.

Everyone thought that Martha Mathy was trying to start a new fashion trend when she started wearing socks that did not match. her "look" started to catch on, and pretty soon all the kids at her school were wearing mixed-up socks, too. Rita Writer, a reporter for the school paper, interviewed Martha about the new sock trend. " Wat gave you the idea to wear mismatched socks?" Rita Asked.
"Its simple mathematics," Martha replied. "you see, I have 18 socks at home but no two are the same. with just these 18 socks, I can create over 100 unique pairs of mismatched socks." Rita found this hard to believe, so she checked it out. Was Martha correct?
Answer:
There are 153 combinations
Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)
= 18 * 17 / 2 = 153
OK that is the maths - now the explanation
The first sock can be any of 18
The second sock can be any of 17 (one already been selected and they must be mismatched)
Therefore there are 18*17 = 306 permutations she could make
However the question asks for "combinations" not "permutations"
A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.
Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153
FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!

A sum amount
to rupees 34476 in two and a half years at 4% CI. the sum is
Given:
Amount = Rs. 34476
Rate of compound interest = 4%
Time = [tex]2\dfrac{1}{2}=2.5[/tex] years
To find:
The principal value.
Solution:
Formula for amount is
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, P is principal value, r is rate of interest and t is time in years.
Putting the given values, we get
[tex]34476=P\left(1+\dfrac{4}{100}\right)^{2.5}[/tex]
[tex]34476=P\left(1+0.04\right)^{2.5}[/tex]
[tex]34476=P\left(1.04\right)^{2.5}[/tex]
[tex]\dfrac{34476}{\left(1.04\right)^{2.5}}=P[/tex]
Now,
[tex]P=31256.0090[/tex]
[tex]P\approx 31256[/tex]
Therefore, the value of sum or principal value is Rs.31256.

Step-by-step explanation:
Let the total value be T. If he gave them 33% each, they received

Expand 6(3x-5)
I know it looks easy but I can't
Answer:
18x - 30
Step-by-step explanation:
in order to expand the expression, you need to use the distributive property to simplify 6(3x - 5).
first, distribute 6 to 3x, which is just 6 • 3x.
6 • 3x = 18xnow distribute 6 to -5, which is just 6 • -5.
6 • -5 = -30therefore, 6(3x - 5) expanded is 18x - 30 :) i hope this helps!! have a lovely rest of your day <3

Companies use employee training for various reasons, including employee loyalty, certification, quality, and process improvement. In a national survey of companies, BI Learning Systems reported that 56% of the responding companies named employee retention as a top reason for training. Suppose 38% of the companies replied that they use training for process improvement and for employee retention. In addition, suppose that of the companies that use training for process improvement, 89% use training for employee retention. A company that uses training is randomly selected. a. What is the probability that the company uses training for employee retention and not for process improvement
Answer:
0.3081 = 30.81% probability that the company uses training for employee retention and not for process improvement
Step-by-step explanation:
56% employee retention.
38% for process improvement. Of those, 89% for employee retention.
a. What is the probability that the company uses training for employee retention and not for process improvement
The 56% is composed by:
x of 100 - 38 = 72%(not for process improvement)
89% of 38%(for process improvement).
We want to find x. So
[tex]0.72x + 0.89*0.38 = 0.56[/tex]
[tex]0.72x = 0.56 - 0.89*0.38[/tex]
[tex]x = \frac{0.56 - 0.89*0.38}{0.72}[/tex]
[tex]x = 0.3081[/tex]
0.3081 = 30.81% probability that the company uses training for employee retention and not for process improvement
