Answer:

Total rainfall = 39 inches.

Step-by-step explanation:

The question is not properly qualified. I am assuming that the first month, 12 inches of rain fell (that is an awful lot) and for the next 9 months the rainfall was 3 inches per month.

Let R be the total rainfall.

R = first month + 9*3

R = 12 + 27

R = 39

Answer:

f(x) = cos(x)

Step-by-step explanation:

Given the expression

[tex]tan(x)csc(c) = \frac{1}{f(x)}[/tex]

Recall that;

[tex]tan(x) = \frac{sin(x)}{cos(x)} \\csc(x) = \frac{1}{sin(x)} \\[/tex]

Substitute into the given expression

[tex]tan(x)csc(c) = \frac{1}{f(x)}\\\frac{sin(x)}{cos(x)} \frac{1}{sin(x)} = \frac{1}{f(x)}\\\frac{1}{cos(x)} = \frac{1}{f(x)}[/tex]

Cross multiply

[tex]cos(x) = f(x)\\Swap\\f(x) = cos(x)[/tex]

Answer:

The p-value is approximately 0.0508

Step-by-step explanation:

The given parameters are;

The expected mass of banana chips bag filled by the machine, μ = 421 gams

The number of bags in the sample of bags filled by the machine, n = 26 bags

The mean mass of the bags in the sample, [tex]\overline x[/tex] = 413 grams

The standard deviation of the mass in the bags, s = 24 grams

The level of significance, α = 0.02

The null hypothesis, H₀; μ = 421 grams

The alternative hypothesis, Hₐ; μ < 421 grams

The test statistic is given as follows;

[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]

We get;

[tex]t=\dfrac{413-421 }{\dfrac{24}{\sqrt{26}}} \approx -1.6996731712[/tex]

The t-value = -1.6996731712

The degrees of freedom df = n - 1 = 26 - 1 = 25

From an online source, we get the critical-t =  2.166587

The p-value is obtained using an online source as p(t ≤  -1.6996731712) = 0.0508

From the p-value table, we get

0.05 < p < 0.1

Answer:

The population is decreasing by 13%.

Step-by-step explanation:

The standard exponential equation can be modeled by:

y = A(1 ± r)^x

Answer:

$22.12

Step-by-step explanation:

Let x be the wholesale price (the price before adding the markup).

The markup is 13%, so 13% of x is added to x.

x + 13%x = $25

x + 0.13x = 25

1.13x = 25

x = 25/1.13

x = 22.12

Answer:

angle 1 = 63°

angle 2 = 117°

angle 3 = 63°

Step-by-step explanation:

angle 2 = 117° (vert.opp.angles)

angle 1 = angle 3 (vert.opp.angles)

angle 1 + angle 2 + angle 3 + 117° = 360°

angle 1 + 117° + angle 3 + 117° = 360°

angle 1 + angle 3 = 360° - 117° - 117°

angle 1 + angle 3 = 126°

angle 1 = 63°

angle 3 = 63°

1. The stochastic matrix for the given transitions is:

   [tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]

2. 40.0% people in February and 32.0% people in March will be the low  users if there are 50% low users in January.

It is given that,

80% of the people who were Low users one month will be Low users the next month.

That means for the transition low-low (L-L)

p = 0.80

So, for Low-high transition (L-H)

p = 1-0.80 = 0.20

It is also given that 70% of the people who were High users one month will be High users the next month.

That means, p = 0.70 for the transition high-high (H-H)

Then for H-L transition, p = 1-0.70 = 0.30

(a) The 2x2 stochastic matrix for these transitions is:

[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]

(b) Given that 50% users are the low users in month of January.

[tex]\text{Percent of the customers will be Low users in February}= (\text{low users in month of January} \times \text{Probability of L-L transition.}) \times 100\%[/tex]= (0.50 x 0.80)x100%

= 0.4x 100%

=40.0%

Now, the percentage of people who will be low users in the month of march = (low users in February x probability of L-L transition)x100%

=(0.40x0.80)x100%

=0.32x100%

=32.0%

Hence, the percentage of people who will be low users in the month of February and in the month of March are 40.0% and 32.0% respectively.

Therefore, the results are:

1.2x2 stochastic matrix for the transitions is as:

         [tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]

2. The percentage of people who will be low users in the month of     February and in the month of March are 40.0% and 32.0% respectively.

Answer:

No, you need to know another  angle to prove that it is a right triangle to use the Pythagorean theorem.

If you did have an additional side length, that needed angle could be calculated and then use the Pythagorean to prove.

Answer:

The father is 54 years old

Step-by-step explanation:

Well from the ratio 9:4

We know the son is 24

we can divide 24/4 to get 6

now we know we have to multiply by 6 on each side of the ratio to get the final result

54:24

Answer:

54 years old

Step-by-step explanation:

Because the son is 24 years old, we know that that is 6 times the '4' in the ratio 9:4 therefore if we do 6*9=54 that is the age of his father!

Find:

Rate of interest r

Computation:

A = p[1+r]ⁿ

Answer:

(2,4)

Step-by-step explanation:

The coordinate of A is (2,-4) currently. If we reflect that point over the x-axis,  the y coordinate will change into the opposite sign. Because the y coordinate is -4, it will change to - (-4) = 4. Therefore, the coordinate of A' would be (2,4).
