In order to conduct an experiment five subjects are randomly selected from a group of 48 subjects how many different groups of five subjects are possible
Answer:
1,712,304 ways
Step-by-step explanation:
This problem bothers on combination
Since we are to select 5 subjects from a pool of 48 subjects, the number of ways this can be done is expressed as;
48C5 = 48!/(48-5)!5!
48C5 = 48!/43!5!
48C5 = 48×47×46×45×44×43!/43!5!
48C5 = 48×47×46×45×44/5!
48C5 = 205,476,480/120
48C5 = 1,712,304
Hence this can be done in 1,712,304ways
i cant figure the answer out can u help me (x+6)(3x-8)
Answer:
3x² + 10x - 48
Step-by-step explanation:
Given
(x + 6)(3x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(3x - 8) + 6(3x - 8) ← distribute both parenthesis
= 3x² - 8x + 18x - 48 ← collect like terms
= 3x² + 10x - 48

Answer the photo below thanks
Answer:
You're right, the answer is C.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
I am not sure if it is B or C, but I can say that it is not A since the figure in A is rotated. Figure in B kinda looks like a reflection then C because if the figures were translated then the corner should be at one side. Sorry if that kinda confused you, but I added a picture of what I am trying to say for the figure in option B. I guess it is C.
Hope this helps, thank you !!
solve this please for me
Answer:
c is answer plz see the pic it's the solution
Equations & Inequalities The value of a baseball card is increasing at a rate of $40 per year. If Tom purchased the card for $300, how many years will it take for the card to at least triple in value?
Answer:
15= number of years
Step-by-step explanation:
Giving the following information:
Current value= $300
Growth per year= $40
Triple value= $900
To calculate the number of years it will take to transform $300 into $900, we need to use the following formula:
Future value= current value + (growth rate per year*number of years)
900 = 300 + (40*number of years)
600= 40number of years
600/40= number of years
15= number of years

Helen plays basketball. For free throws, she makes the shot 75% of the time. Helen must now attempt two free throws. The probability that Helen makes the second free throw given that she made the first is 0.85. What is the probability that she makes both free throws?
Answer: 0.6375
Step-by-step explanation:
Let's assume that the event that she'll make the first shot is given as P(A) while making the second shot is P(B). Therefore, P(A/B) = 0.85
Therefore, the probability that she makes both free throws will be denoted as:
= 0.75 × 0.85
= 0.6375
Greg’s family went to the movie theater and bought tickets and popcorn. They spent $35 altogether with $9.50 spent on popcorn. Write an equation that can be used to find out how much money x they spent on tickets.
Answer:
x + 9.50 = 35
Step-by-step explanation:
The missing variable in this case is the number of dollars they spent on tickets. In total, combined the tickets and popcorn is equal to 35$,
We already know the amount they spent on popcorn.
X, the amount they spent on tickets + 9.50=35
Si: a + b + c = 18
hallar: abc + bca + cab
Answer:
abc + bca + cab
abc(1+1+1)
3×18
54
Answer:
54
Step-by-step explanation:
a + b + c = 18
abc + bca + cab = ???
18 / 3 = 6
a = ? = 6
b = ? = 6
c = ? = 6
(6 + 6 + 6) + (6 + 6 + 6) + (6 + 6 + 6)
(18) + (18) + (18)
abc + bca + cab = 54
6/3 + -1/6 reduce this equation to the simplest form
Answer:
12/6-1/6=11/6 simplified to 1 5/6
Step-by-step explanation:
to make this easier make sure all fractions have the same denominator 6/3x2/2=12/6 since they now have the same denominator add 12/6+-1/6=11/6
adding a negative(6/3+-1/6) is the same as subtracting a positive(6/3-1/6)
Answer:
1 5/6

how do I find the percent of budget?
Answer:
First, subtract the budgeted amount from the actual expense. If this expense was over budget, then the result will be positive.
Next, divide that number by the original budgeted amount and then multiply the result by 100 to get the percentage over budget. If your expenses were lower than your budgeted amount, then this number will be negative, describing the percentage under budget.

Answer:
y = 4Step-by-step explanation:
x + 2y = 10 ⇒ 2y - 10 = -x
-x + 4y = 14
2y - 10 + 4y = 14
6y = 24
y = 4
Please answer I need it asap!!!
Answer:
Use ratios of corresponding sides:
EH/FH = FH/GHFH² = EH*GH4.
FH² = 6*3 ⇒ FH = √18 = 3√25.
GH = FH²/EH = 6²/12 = 36.
FH = √(19-15)*15 = √60 = 2√15If the lines in a system of equations have different slopes and the same y-intercept, how many solutions does the system have?

Answer:
11) x = 9
12) x = 9
Step-by-step explanation:
11) Corresponding segments are proportional, so ...
x/6 = 12/8
x = 6(12)/8 . . . multiply by 6
x = 9
__
12) Similar triangle relationships show you the geometric mean relationship that applies in this case.
long side/short side = x/3 = 27/x
x² = 3·27 . . . . . . cross multiply
x = √(3·27) . . . . geometric mean relationship
x = 9

Isabel put $4,000 into a saving account that pays interest monthly at a simple-interest rate of 2.5% per year. If she takes the interest interest out of the account each month, how much money should she expect to earn after 6 months?
9514 1404 393
Answer:
$49.98
Step-by-step explanation:
The interest credited to Isabel's account each month is ...
I = Prt
I = $4000·(0.025)(1/12) = $8.33
If she withdraws that amount each month, the original balance is restored, and she will earn the same amount the next month.
Isabel's total earnings in 6 months will be ...
$8.33 · 6 = $49.98
