Based on the information provided, the most appropriate answer is option (c): P value is about 0.2706 and is to the right of the mean.

To determine whether the claim made by Orange Mobiles is supported by the data, a hypothesis test can be conducted. The null hypothesis (H0) would state that the average battery life is 7 hours, while the alternative hypothesis (Ha) would state that the average battery life is less than 7 hours.

By comparing the sample mean (6.9 hours) to the claimed population mean (7 hours) and considering the standard deviation (2 hours), a t-test or z-test can be performed to calculate the p-value. The p-value represents the probability of observing a sample mean as extreme or more extreme than the observed value, assuming the null hypothesis is true.

In this case, the p-value is approximately 0.2706, and since it is greater than the conventional significance level (e.g., 0.05), we fail to reject the null hypothesis. This suggests that there is insufficient evidence to conclude that the average battery life is less than 7 hours.

If Hank has the choice of taking out a 30-year loan for $165,000 at 9.1% interest. The amount that the monthly payment for the 20-year loan is more than the monthly payment for the 30-year loan is: B. $155.66.

For 30-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 30years × 12 months = 360

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^360 / (1+0.00758)^360 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^360 / (1.00758)^360 -1

Monthly payment = 18,957.7574/14.15771760

Monthly payment = $1,339.04

For 20-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 20years × 12 months = 240

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^240 / (1+0.00758)^240 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^240 / (1.00758)^240 -1

Monthly payment = 7,660.239666/5.12476186615

Monthly payment = $1,494.7

Difference = $1,339.04 - $1,494.7

Difference = $155.66

Therefore the correct option is B.

A connected graph can be disconnected by removing vertices if and only if it is not a complete graph.

A connected graph is one where there exists a path between any pair of vertices. Removing any vertex from a complete graph will result in a disconnected graph since there will be at least one pair of vertices that are no longer connected. Therefore, a complete graph cannot be disconnected by removing vertices.

On the other hand, if a graph is not a complete graph, it means that there exist at least two vertices that are not connected by an edge. By removing these vertices, we effectively disconnect the graph since there is no longer a path between them.

Thus, it is possible to remove vertices to disconnect a graph that is not a complete graph.

A complete graph cannot be disconnected by removing vertices, while a non-complete graph can be disconnected by removing appropriate vertices.

The area of the region between the graph of y=4−x2 and the x-axis is 10.67 square units. The solution has been obtained by using the integration method.

The area between the graph of y = 4−x2 and the x-axis is obtained by finding the integral from a to b of the function f(x), which is given by f(x) = 4-x2 .

Therefore, the area of the region between the graph of y=4−x2 and the x-axis is given by the definite integral as follows:

Integral of f(x) = Integral of 4 - x2 dx = [4x - (x3/3)] as limits of integration (x = -2 and x = 2)

By plugging in these limits of integration, we get the value of the area of the region as follows:

Therefore, the area of the region between the graph of y=4−x2 and the x-axis is 10.67 square units.

The probability that the coin lands on heads if one of them is flipped and lands on heads with probability 0.6 is 0.6 × 1/2 + 0.3 × 1/2 = 0.45. Therefore, the probability that the coin lands on heads is 0.45.  

a) Let A be the event that the chosen coin is the one that lands on heads with probability 0.6 and B be the event that the coin lands on heads. Then, the required probability is P(A | B) = P(A and B) / P(B) .

Here, P(A and B) = probability that the chosen coin is the one that lands on heads with probability 0.6 and it actually lands on heads.

Since the probability that the coin lands on heads are 0.45 and the probability that the chosen coin is the one that lands on heads with a probability of 0.6 is 1/2, we have P(A and B) = 0.6 × 1/2 = 0.3. The probability that the coin lands on heads is 0.45.

So, P(B) = probability that the coin lands on heads = 0.45.P(A | B) = P(A and B) / P(B) = 0.3 / 0.45 = 2/3.

The number of bricks in total is = 3x

For the second day, x =4

Number of the bricks he laid on the second day = 12

Now the x =12 for the third day.

Number of the bricks he laid on the third day = 36

Now x = 36 for the fourth day.

Number of the bricks he laid on the fourth day = 108

Now the x = 108 for the fifth day.

Since your retirement fund earns a 4.03% annual interest rate compounded continuously, we'll need to use the continuous compounding formula: A(t) = P * e^(rt)

where:
A(t) = value of the account after t years
P = principal amount (initial investment)
e = the base of the natural logarithm, approximately 2.718
r = interest rate (as a decimal)
t = number of years

Given that you've invested $25,000 (P) at a 4.03% interest rate (r = 0.0403), we'll find the value of the account after 10 years (t = 10).
A(10) = 25000 * e^(0.0403 * 10)

Now, calculate the value:
A(10) = 25000 * e^0.403
A(10) = 25000 * 1.4963 (rounded to 4 decimal places)

Finally, find the total value:
A(10) = 37357.50

After 10 years, the value of the account will be $37,357.50 (rounded to 2 decimal places).

Note that there is no indication of fraud in this scenario, and the interest rate used is 4.03%.

A statement about the system of equations that is true is: A. in the system of equations, x represents the number of liters of acid in solution A, and y represents the number of liters of acid in solution B.

The expression 0.30y represents: B. the number of liters of acid in solution C that come from solution B.

If the system of equations is graphed in a coordinate plane, the x-coordinate of the intersection of the two lines is 2.5.

The number of liters of solution B the chemist mixes with solution

A to create solution C containing 25% acid is 7.5 liters.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of liters of acid in solution A and the number of liters of acid in solution B respectively, and then translate the word problem into an algebraic equation (linear equations) as follows:

Since the chemist mixed the two solutions to make 10 liters of a third solution, solution C, containing 25% acid, a system of linear equations that models the situation is given by;

x + y = 10

10%x + 30%y = 25% ⇒ 0.10x + 0.3y = 2.5

By solving the system of linear equations simultaneously, we have:

0.10(10 - y) + 0.3y = 2.5

y = 7.5 liters.

x = 10 - y = 10 - 7.5 = 2.5 liters.

Step-by-step explanation:

The Malthusian law for population growth states that the rate of population growth is proportional to the current population size.

Mathematically, we can express this as:

dP/dt = rP

where P is the population size, t is time, and r is the growth rate.

Assuming a constant growth rate, we can integrate this equation to get:

ln(P) = rt + C

where C is an integration constant. We can solve for C using the initial population estimate:

ln(1200) = r(1980) + C

C = ln(1200) - r(1980)

Substituting the values of C and P from the second estimate (P=7500 in 2008), we get:

ln(7500) = r(2008) + ln(1200) - r(1980)

Solving for r, we get:

r = [ln(7500) - ln(1200)] / (2008 - 1980) = 0.0496

Using this value of r, we can predict the alligator population in 2020, which is 12 years after the second estimate (2008). We have:

ln(P) = rt + ln(7500)

ln(P) = 0.0496(12) + ln(7500) = 9.058

P = e^9.058 = 8656

Therefore, the estimated alligator population in the region in the year 2020 is 8656.
