Answer:
Part A- 6
Part B- 3
Part C- 3/22100
Step-by-step explanation:
Part A-
Use the permutation formula and plug in 3 for n and 2 for k.
nPr=n!/(n-k)!
3P2=3!/(3-2)!
Simplify.
3P2=3!/1!
3P2=6
Part B-
Use the combination formula and plug in 3 for n and 2 for k.
nCk=n!/k!(n-k)!
3C2=3!/2!(3-2)!
Simplify.
3C2=3!/2!(1!)
3C2=3
Part C-
It is given that the total number of three-card hands that can be dealt from a deck of 52 cards is 22100. Use the fact that the probability of something equals the total successful outcomes over the sample space. In this case the total successful outcomes is 3 and the sample space is 22100.
I believe the answer is 3/22100
I honestly suck at probability but I tried my best.
Answer:
the equation for a line is y=MX+b
m= slope(rise/run)
x=variable
b= y intercept
you would find the slope by looking at the rise over run which are both 1 and the line is negative so the slope would be negative one
you would find b by looking at where the y intercept is (y when x is zero) which is 9
y= -x+9
hope that helped
Distributive property is used when you have a number outside a set of numbers in parenthesis.
Using the distributive property, you multiply the number outside the parenthesis by each number inside the parenthesis.
The first answer is correct because they are multiplying 9 by 20 and adding it to 9 multiplied by 6.
Answer:
45.2%
Step-by-step explanation:
To convert 0.452 to a percentage, multiply the number 0.452 by 100.
To give you the total cost of the sweater you do:
18.74 × 1.06 = 19.8664
Which will be rounded to $19.87 because the measurement is currency (2 d.p.).
Therefore, you do have enough because $20 > $19.87.
