Answer:
10 feet
Step-by-step explanation:
Multiply 20 by 6 which will give the answer 120 (in inches). Then convert 120(inches) to feet by dividing with 12.The answer will be 10(feet) needed for six shelves.20x6= 120
120/12=10
=10 ft
Please help me solve this problem
Answer:
D, 225
Step-by-step explanation:
Because this equation already has a1, it's useless to test with that, so instead solve for a2.
You would have a2 - 5a1, which would get you a2 = 5(9) because we already know what a1 is, which is 9. a2 = 45
Now we have a2, which is 45, so now we solve for a3
We would have a3 = 5a2 = a3 = 5(45) which is 225 which is a3

Claire is 11 years old. She is 5 years younger than her brother Gary who is y years old. Which equation represents this situation?
Answer:
y = 11 + 5
Step-by-step explanation:
So she is 5 years younger, which would mean that it would be y - 5, and using inverse operations, we get y = 11 + 5

There are 4 green marbles and 2 red marbles in the jar. You just randomly draw one by one without replacement and stop when you get the first red marble. Let X be the number of green marbles you draw when you stop. Get the probability distribution of X and find the expectation of it
Answer:
Then the probability distribution is:
P(0) = 1/3
P(1) = 4/15
P(2) = 1/5
P(3) = 2/15
P(4) = 1/15
The expected value for X is:
EV = 1.33...
Step-by-step explanation:
We have a total of 6 marbles in the jar.
The probability of getting a red marble in the first try (X = 0) is equal to the quotient between the number of red marbles and the total number of marbles, this is:
P(0) = 2/6 = 1/3
The probability of drawing one green marble (X = 1)
is:
First, you draw a green marble with a probability of 4/6
Then you draw the red one, but now there are 5 marbles in the jar (2 red ones and 3 green ones), then the probability is 2/5
The joint probability is:
P(1) = (4/6)*(2/5) = (2/3)*(2/5) = 4/15
The probability of drawing two green marbles (X = 2)
Again, first we draw a green marble with a probability of 4/6
Now we draw again a green marble, now there are 3 green marbles and 5 total marbles in the jar, so this time the probability is 3/5
Now we draw the red marble (there are 2 red marbles and 4 total marbles in the jar), with a probability of 2/4
The joint probability is:
P(2) = (4/6)*(3/5)*(2/4) = (2/6)*(3/5) = 1/5
The probability of drawing 3 green marbles (X = 3)
At this point you may already understand the pattern:
First, we draw a green marble with a probability 4/6
second, we draw a green marble with a probability 3/5
third, we draw a green marble with a probability 2/4
finally, we draw a red marble with a probability 2/3
The joint probability is:
P(3) = (4/6)*(3/5)*(2/4)*(2/3) = (2/6)*(3/5)*(2/3) = (1/5)*(2/3) = (2/15)
Finally, the probability of drawing four green marbles (X = 4) is given by:
First, we draw a green marble with a probability 4/6
second, we draw a green marble with a probability 3/5
third, we draw a green marble with a probability 2/4
fourth, we draw a green marble with a probability 1/3
Finally, we draw a red marble with a probability 2/2 = 1
The joint probability is:
P(4) = (4/6)*(3/5)*(2/4)*(1/3)*1 = (1/5)*(1/3) = 1/15
Then the probability distribution is:
P(0) = 1/3
P(1) = 4/15
P(2) = 1/5
P(3) = 2/15
P(4) = 1/15
The expected value will be:
EV = 0*P(0) + 1*P(1) + 2*P(2) + 3*P(3) + 4*P(4)
EV = 1*(4/15) + 2*( 1/5) + 3*( 2/15) + 4*(1/15 ) = 1.33
So we can expect to draw 1.33 green marbles in this experiment.

-. A businessman plans to retire in 30 years. As part of his retirement plan, he has
invested $8,000 in a public utility bond that will increase his investment at a rate of
6% per year, compounded annually. Which is the best approximation of the value of
the investment after 30 years?
Answer:
A = $45948
Step-by-step explanation:
Given the following data;
Principal = $8000
Interest rate = 6% = 6/100 = 0.06
Time = 30 years
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 8000(1 + \frac{6}{100})^{30}[/tex]
[tex] A = 8000(1 + 0.06)^{30}[/tex]
[tex] A = 8000(1.06)^{30}[/tex]
[tex] A = 8000(5.7435)[/tex]
A = $45948

Answer:
The answer would be a. G and C.
Step-by-step explanation:
When calculating G/C, 329/261.6= 1.49847 rounded.
We are looking for the closest integer ratio to that number which is 3 to 2. A 3/2 ratio =1.5 which is as close to 1.49847 as you are going to get with a ratio. Hope this helps!
the inches of rainfall on mount waiale on Kauai in Hawaii is represented by the function f(x)=3^x+1-22 scientist are useing equations to study rain fall from year to year.
Calculate how much rainfall there was in year four and In year nine. You must show all of your work and calculate.
Answer:
[tex] \textrm {221 in year 4} \\ \textrm{59027 in year 9}[/tex]
Step-by-step explanation:
we are given a function
[tex] \displaystyle f(x) = {3}^{x + 1} - 22[/tex]
where x represents the years f(x) represents the amount of rainfall
so to figure out the amount of rainfall in year 4 we can substitute 4 for x
[tex] \displaystyle f(4) = {3}^{4+ 1} - 22[/tex]
simplify addition:
[tex] \displaystyle f(4) = {3}^{5} - 22[/tex]
simplify square:
[tex] \displaystyle f(4) = 243- 22[/tex]
simplify substraction:
[tex] \displaystyle f(4) = 221[/tex]
likewise In the year 9
[tex] \displaystyle f(9) = {3}^{9 + 1} - 22[/tex]
simplify addition:
[tex] \displaystyle f(9) = {3}^{10} - 22[/tex]
simplify square:
[tex] \displaystyle f(9) = 59049 - 22[/tex]
simplify Substraction:
[tex] \displaystyle f(9) = 59027[/tex]
hence,
there was 221 and 59027 in year four and In year nine
