Answer:

3.1891

Step-by-step explanation:

Common logarithms are logarithms with base 10.

So the magnitude of Tallahassee: [tex]log_{10}(1.7*10^5)[/tex]

And the magnitude of Bascom: [tex]log_{10}(1.1*10^2)[/tex]

Difference between the two is: [tex]log_{10}(1.7*10^5)-log_{10}(1.1*10^2)[/tex]

Type: "[tex]log(1.7*10^5)-log(1.1*10^2)[/tex]" into calculator to get: 3.1891

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

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:

y = -2.5x + 5

Step-by-step explanation:

10x + 4y = 20

Subtract 10x from both sides.

4y = -10x + 20

Divide both sides by 4.

y = -2.5x + 5

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

Answer:

A) x¯ = 134.5

s² = 276.7 is the same for both formulas

s = 16.634

B) At 68.26%, we have (117.866, 151.134)

At 95.44%, we have (101.232, 167.768)

At 99.73%, we have (84.598, 184.402)

C) Yes, it will be considered high because 190 doesn't fall between any of the 3 tolerance intervals gotten in B above.

Step-by-step explanation:

A) The random 6 entertainment expenses are;

$157, $132, $109, $145, $125, $139

We want to find x¯ which is the mean.

Thus;

x¯ = (Σx)/n

x¯ = (157 + 132 + 109 + 145 + 125 + 139)/6

x¯ = 134.5

s² is the variance and can be calculated from 2 different formulas which are;

s² = (Σ(x - x¯)²)/n

Or s² = ((Σx²) - (Σx)²/n)/(n - 1)

For the first formula, when calculated we have;

s² = [(157−134.5)² + (132−134.5)² +(109−134.5)² + (145−134.5)² +(125−134.5)² + (139−134.5)²]/6

s² = 276.7

For the second formula;

(Σx²) = (157)² + (132)² + (109)² + (145)² +(125)² + (139)² = 109925

(Σx) = (157 + 132 + 109 + 145 + 125 + 139) = 807

Thus;

s² = (109925 - (807²/6))/(6 - 1)

s² = 276.7

So both formulas gave the same result of s²

s = √s² = √276.7

s = 16.634

B) from the empirical rule, 68% of the data will fall within one standard deviation while 95% of the data will fall within two standard deviations, and then 99.7% of the data will fall within three standard deviations from the mean.

Now, 68.26% will correspond to 1 standard deviation from the means and the tolerance level Formula here is;

x¯ ± s = 134.5 ± 16.634

This gives; (117.866, 151.134)

95.44% will correspond to within 2 standard deviations and the formula here is;

x¯ ± 2s = 134.5 ± 2(16.634)

>> (101.232, 167.768)

99.73% will correspond to within 3 standard deviations and the formula here is;

x¯ ± 3s = 134.5 ± 3(16.634)

>> (84.598, 184.402)

C) Yes it would be considered high because it doesn't fall between any of the 3 intervals in B above.

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.
