When selecting r objects out of a pool of n objects, the number of ways this can be done is:
nCr = n!/(n-r)!r!
If a local BBQ restaurants offers 2 side dishes with a lunch plate, and there are 7 side dishes, the number of choices that the customer have is expressed as:
7C2 = 7!/(7-2)!2!
7C2 = 7!/(5)!2!
7C2 = 7*6*5!/5! * 2
7C2 = 7*6/2
7C2 = 42/2
7C2 = 21 choices
Hence the customer has 21 choices of side dishes to make

Which decimal is the best best estimate of the fraction 29/40?
Answer: 0.725
Step-by-step explanation: this is the answer. in order to get to this answer you would put The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.

It is assumed that the test results for a class follow a normal distribution with a mean of 78 and a standard deviation of 36. If you know that a student's grade is greater than 72, what is the probability that it is greater than 84
Answer: 0.4337
Step-by-step explanation:
Let X represents the test results for a class that follow a normal distribution .
Given: Mean [tex]\mu=78[/tex], Standard deviation [tex]\sigma=36[/tex]
Then, the probability that it is greater than 84 will be
[tex]P(X>84)=P(\dfrac{X-\mu}{\sigma}>\dfrac{84-78}{36})\\\\=P(Z>0.167)\ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z<0.167)\\\\=1-0.5663=0.4337\ [\text{By p-value table}][/tex]
Hence, the required probability = 0.4337

Twice Bill's number added to 80 is 112
Answer:
Equation: 2x + 80 = 112
Bill's Number: 16
Step-by-step explanation:
Step 1:
2x + 80 = 112
Step 2:
2x = 112 - 80 Subtract 80 on both sides
Step 3:
x = 32 ÷ 2 Divide
Answer:
x = 16

Jane lose 4.7 miles from the local ice cream parlor wow Sarah lives only 3.4 miles from the same ice cream parlor how many more feet away from the parlor does Jane live? Explain how you got the answer.
9514 1404 393
Answer:
6864 ft
Step-by-step explanation:
In miles, the difference of distances is ...
4.7 mi - 3.4 mi = 1.3 mi
We know there are 5280 feet per mile. In feet, that distance is ...
(1.3 mi)×(5280 ft)/(1 mi) = (1.3×5280) ft = 6864 ft
Jane lives 6864 feet farther from the parlor than Sarah.
Answer: If we’re talking terms of subtraction, then it would be 1.3. Now if we’re talking feet, what the other guy said.
Step-by-step explanation:
4.7-3.4=1.3
What is 23 x 2 (4 + 3) x 20 + 6
Pls need help, I will mark you as brainiest
Answer:
328
Step-by-step explanation:
For these questions we need to use BODMAS method
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
First we need to see if there are any brackets
(4 + 3) = 7
After that we need to find if there is any power
- No power
After that we need to find if there is either multiplication or division
23 x 2 = 46
46 x (4 + 3) = 46 x 7 = 322
Now we need to simplify so , we don't get confused
23 x 2 x (4 + 3) x 20 = 322
322 + 6 = 328
We have simplified the answer as much as we can
Answer = 328
Hope you understand

Elena spent $2.50 on pineapple juice. Pineapple juice costs $0.10 per ounce. How many ounces of pineapple juice did Elena buy?
Answer:
Elena bought 25 ounces of pineapple juice
Step-by-step explanation:
We know that however many ounces of pineapple juice Elena bought must equal to the
$2.50she spent.
We also know that it costs
$0.10 per ounce
Let's let x be the number of ounces of pineapple juice that Elena bought:
0.10x=2.50
We get: x=25
HELP ME IM CHOOSING BRAINLEST IF U GET IT RIGHT
The slope for this graph will be 2
Answer:
2
Step-by-step explanation:
you use the rise over run formula. as you can see, the line hits certain points. You count how many points it is above and over, and that is 2 over 1. Remember, lines always go from left to right, so if it goes diagonal downward, it's a negative slope.
What is the y-intercept of the equation of the line that is perpendicular to the line y=3/5x+10 and passes through the
point (15,-5)?
O y=x-20
O y=-3x+20
0 v= 2 X-20
O y=-3x+20
Answer: y=-5/3x+20 or y=-1 2/3x+20, so 20.
Step-by-step explanation: Actually, neither one of those options are correct. You may recall that the slope of the perpendicular line would be the exact opposite, the reciprocal, of the given line. The exact opposite of 3/5x is -5/3x, which could be reduced to -1.5x. From there, you could substitute x and y, which are 15 and -5 in this case, into the y=mx+b equation:
-5=-5/3(15)+b *b is y-intercept*
-5=-25+b Multiplied -5/3 by 15 first
-20=b Subtracted -25 from both sides (it'd be --25, so
basically just +25)
20=b Reciprocate b because you need the opposite

Solution
y = 2x – 7
4 + y = 12
Answer:
x = 15/2 (15 over 2)
y = 8
Step-by-step explanation:
there 3 different way to do this (substitution, Elimination and Matrix)
ill be showing substitution ( you use the answer of one of the variables and substitute it for the other questions variable)
4 + y = 12
y = 12 -4
y = 8
y = -2x - 7
8 = 2x - 7
8 + 7 = 2x
15 = 2x
x = 15/2
hope this helped and made a little sense!
Write the equation of a line that is parallel to y=-7x+5 and which passes through the point (-1, -6).
Answer:
y = -7x - 13
Step-by-step explanation:
When graphing a great website to use is desmos graphing calculator. In it I put in the equation you gave me and the point (-1,-6). When making a parallel equation it should have the same slope as the original problem, so -7. I then set up the equation for y = -7x, since that is what the know and put in numbers to the y-intercept till it matched up with the dot. Making the equation y = -7x - 13

Determine whether the set is well defined.
1) The set of manufacturers of televisions that enjoyed sizeable profits in 1996
A) not well defined
B) well defined
Answer:
A) not well defined
Step-by-step explanation:
A set is said to be a well-defined set when we can clearly state whether something belongs to that set or not without any trace of ambiguity.
This implies that based on the information provided, we can easily decide on the members of a well defined set. A set that is not well defined carries some level of ambiguity regarding what and what should be part of the set.
In this case, 'sizeable profits' was not clearly defined. There ought to have been a threshold of profit defined as sizeable (e.g profit of $ 1,200,000 and above).
Since there is no such definition of 'sizeable profits', the set is not well defined.

Plz help me !!!! 50 points to whoever answers it correctly. Let the graph of g be a vertical stretch by a factor of 4 and a reflection in the x-axis of the graph of f(x)=x^2-3. Write the equation for g.
Answer:
So there are two answers.
Step-by-step explanation:
One answer is vertical strech which streches it vertically and that equation would be f(x)= -4x^2+3 (this is also reflected across the x-axis)
The other answer is if you want a vertical compression and that equation would be f(x)= -1/4x^2+3 (also reflected across the x-axis)
