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.
Answers
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

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
Answers
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.

Find the measure of the arc or angle indicated. Part 1. NO LINKS.
Answers
Answer:
Step-by-step explanation:
1)
O = center of circle (origin)
we know that the angle at the center of the circle ∠ ROS will be
180= 2(31) + ∠x
180-62 = ∠x
118° = ∠x
The supplemental angle to the 118° will be 62°
62° is the interior angle to arc QR , so
arc QR is also 62°
3)
b/c the intercepted arc YZ = 2* 68=136
then 136+125+? = 360
? = 99°
arc ZX = 99°
5)
O= center point
we are given the two arcs 120 and 70 for both of these we know that the
interior angles will be the same. ∠JOX has a central angle of 120 , then
b/c triangle JOX is an isosceles, we know that the two angles J and X of
the triangle JOX will be 1/2 of 60 , or 30 each
also for
also ∠XOY has an interior angle of 70 so the two angle at X and Y will be 1/2 of 110 , or 55°
now add 55+30 to find X for box XYZJ
85° = ∠X
9514 1404 393
Answer:
1) 62°
3) 99°
5) 85°
Step-by-step explanation:
The relevant relationships are ...
an inscribed angle is half the measure of the arc it interceptsthe total measure of the arcs of a circle is 360°__
1) Arc QR has twice the measure of inscribed angle QSR, so is ...
QR = 2×31° = 62°
__
3) Arc YZ is twice the measure of angle X, so is 2×68° = 136°. The sum of arcs around a circle is 360°, so ...
arc XZ = 360° -125° -136° = 99°
__
5) The sum of arcs around a circle is 360°, so ...
arc JZY = 360° -120° -70° = 170°
Angle X is half the measure of arc JZY, so is ...
angle X = 170°/2 = 85°

-. 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?
Answers
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
