As per the combination method, the number of ways to form a committee with six members if it must have more women than men is 91,350.

The total number of ways to form a committee with six members from the 27 people in the department is:

²⁷C₆ = 27! / (6! * (27 - 6)!) = 134,490

Now, we need to find the number of ways to form a committee with more women than men. We can use the concept of unitary method to do this. Let x be the number of women in the committee, then the number of men in the committee will be (6 - x), since the total number of members in the committee is 6.

Since we need to have more women than men, we have the following inequality:

x > (6 - x)

Simplifying this inequality, we get:

2x > 6

x > 3

Therefore, the number of women in the committee must be greater than 3.

Now, we can use another formula for combinations to find the number of ways to form a committee with more women than men. Let's call this number W, then we have:

W = (¹⁵C₄ x ¹²C₂) + (¹⁵C₅ x ¹²C₁) + (¹⁵C₆ x ¹²C₀)

The first term in this equation represents the number of ways to choose 4 women and 2 men from the department, the second term represents the number of ways to choose 5 women and 1 man, and the third term represents the number of ways to choose 6 women and 0 men.

Using the formula for combinations, we get:

¹⁵C₄ = 15! / (4! * (15 - 4)!) = 1,386

¹²C₂ = 12! / (2! * (12 - 2)!) = 66

¹⁵C₅ = 15! / (5! * (15 - 5)!) = 3,003

¹²C₁ = 12! / (1! * (12 - 1)!) = 12

¹⁵C₆ = 15! / (6! * (15 - 6)!) = 5005

¹²C₀ = 1

Therefore, we have:

= (1,386 x 66) + (3,003 x 12) + (5005 x 1)

= 91,350

Step-by-step explanation:

The number of hawks that can be supported by 250,000 kilograms of producers are 500 hawks.

1 hawk ≈ 500 grams

1 kg = 1,000 grams

According to the 10 percent law, only 10% of the energy is transferred to each trophic level from its lower trophic level. So, in this case, if 250,000 kg is available to the producer (grass), then only 25,000 kg will be available to the primary consumer (mice) and only 2,500 kg will be available to the secondary consumer (snakes). Then, for the tertiary consumer (hawks) will be available about 250 kg.

So, 250 kg = 250,000 grams

Since 500 grams ≈ 1 hawk

Thus, 250,000 grams ≈ 500 hawks

Hence, the number of hawks that can be supported by 250,000 kilograms of producers are 500 hawks.

If you are allocated 1 TB data to use on your phone, it will take you 83.33 years until you run out of your quota of 1 GB/month consumption.

1 Terabyte (TB) = 1,000 Gigabytes (GB

So, 1 TB = 1,000 GB

So, the total data available is 1,000 GB/month

Then, to find how many years it will take until you run out of your quota of 1 GB/month consumption, divide the total data available by the monthly consumption:

1,000 GB/month ÷ 1 GB/month = 1,000 months

To convert months to years, divide by 12:1,000 months ÷ 12 months/year ≈ 83.33 years

Therefore, it will take you 83.33 years until you run out of your quota of 1 GB/month consumption.

x = - 39

Step-by-step explanation:

The Null and Alternative hypothesis are

Hₒ: π= 0.79

Hₐ: π > 0.79

Statistic Z = -26.38

P-value = 0

Conclusion : The null hypothesis is

rejected .

Final Conclusion : which implies that population proportion is different from

π= 0.79.. This sample proportion can notbe product of chance.

There is enough evidence to support to the claim that selection of people is biased against allowing this ethnicity to sit on the grand jury.

We have problem of proportion and we have to apply hypothesis testing in it .

We claim that the selection is biased against allowing this ethnicity to sit on the grand jury. This means that proportion of people of enthic selected for jeury in a way below from proportion that eligible for jury .

Null and Alternative hypothesis are

Hₒ: π= 0.79

Hₐ : π> 0.79

The significance level is 0.01

The sample we will use is total of 876 people that were selected for grand jury duty (n= 876). 42% of them were entnicity for which we are testing , so sample proportion is p= 0.42

The standard error is

σₚ= s√ (π(1-π)/n)= √ 0.79 (1-0.79)/ 876 = √0.00019 = 0.0137~ 0.014

Then we can calculate Z – value

Z = (p-π+0.5/n)/ σₚ =( 0.42 – 0.79 + 0.5/876 )/ 0.014 = - 0.03964/0.014 = - 26.387

P-value for this test statistic is 0

P-value (z<-26.38)= 0

P-value = 0 < 0.01

As we see that P-value is less lower then significance level . This sample result is unpredictable. The null hypothesis is rejected which implies that population proportion is different from π= 0.79

This sample proportion can not be product of chance.

There is enough evidence to support to the claim that selection of people is biased against allowing this ethnicity to sit on the grand jury.

Answer:

b= 4.6

Step-by-step explanation:

use the pythagorean theorem.

Answer:

4.6

Step-by-step explanation:

The scatter plot of the data shows a linear relationship between the number of weeks (x) and the amount of money saved (y).

In the scatter plot, the x-axis represents the number of weeks, and the y-axis represents the amount of money saved. The initial amount of money saved is $10, and each week $5 is added to the savings.

To create the scatter plot, we start with the initial point (0, 10) on the graph, which represents the starting point. Then, for each subsequent week, we add $5 to the y-coordinate and increment the x-coordinate by 1. This process is repeated for the desired number of weeks.

The resulting scatter plot will show a series of points that form a straight line with a positive slope. Each point on the line represents the number of weeks and the corresponding amount of money saved at that time. As the number of weeks increases, the amount of money saved increases linearly.

Overall, the scatter plot visually represents the relationship between the number of weeks and the amount of money saved, showing the incremental growth of savings over time.

Newton's law of cooling describes how the temperature of an object changes over time in response to the surrounding temperature. The equation that governs this process is du/dt = -K(u - T), where u is the temperature of the object at any given time, T is the constant ambient temperature, and K is a positive constant.

To find the temperature of the object at any time, we need to solve this differential equation. First, we can separate the variables by dividing both sides by (u-T), which gives us du/(u-T) = -K dt. Integrating both sides, we get ln|u-T| = -Kt + C, where C is a constant of integration. Exponentiating both sides, we get u-T = e^(-Kt+C), or u(t) = T + Ce^(-Kt).

To find the value of the constant C, we use the initial condition u(0) = u_0. Plugging in t=0 and u(0) = u_0 into the equation above, we get u_0 = T + C. Solving for C, we get C = u_0 - T. Substituting this value of C into the equation for u(t), we get u(t) = T + (u_0 - T)e^(-Kt).

Therefore, the temperature of the object at any time t is given by u(t) = T + (u_0 - T)e^(-Kt).
According to Newton's law of cooling, the temperature u(t) of an object can be determined using the differential equation du/dt = -K(u - T), where T is the constant ambient temperature, and K is a positive constant. To find the temperature of the object at any time, given the initial temperature u(0) = u_0, we need to solve this differential equation.

Step 1: Separate the variables by dividing both sides by (u - T) and multiplying both sides by dt:
(1/(u - T)) du = -K dt

Step 2: Integrate both sides with respect to their respective variables:
∫(1/(u - T)) du = ∫-K dt

Step 3: Evaluate the integrals:
ln|u - T| = -Kt + C, where C is the constant of integration.

Step 4: Take the exponent of both sides to eliminate the natural logarithm:
u - T = e^(-Kt + C)

Step 5: Rearrange the equation to isolate u:
u(t) = T + e^(-Kt + C)

Step 6: Use the initial condition u(0) = u_0 to find the constant C:
u_0 = T + e^(C), so e^C = u_0 - T

Step 7: Substitute the value of e^C back into the equation for u(t):
u(t) = T + (u_0 - T)e^(-Kt)

This equation gives the temperature of the object at any time t, taking into account Newton's law of cooling, the ambient temperature T, and the initial temperature u_0.

Thus, the equation that gives the temperature of the object at any time t, considering the initial temperature u_0 and the ambient temperature T is  u(t) = T + (u_0 - T)e^(-Kt).

According to Newton's law of cooling, the temperature u(t) of an object satisfies the differential equation du/dt = -K(u - T), where T is the constant ambient temperature and K is a positive constant.

Given the initial temperature u(0) = u_0, we can solve this differential equation to find the temperature of the object at any time.

To solve the differential equation, we can use separation of variables:
1/(u - T) du = -K dt

Integrate both sides:
∫(1/(u - T)) du = ∫(-K) dt
ln|u - T| = -Kt + C (where C is the integration constant)

Now, we can solve for u(t):
u - T = Ce^(-Kt)

To find the constant C, we use the initial condition u(0) = u_0:
u_0 - T = Ce^(-K*0)
u_0 - T = C

So, our temperature function is:
u(t) = T + (u_0 - T)e^(-Kt)

This equation gives the temperature of the object at any time t, considering the initial temperature u_0 and the ambient temperature T.

Carlos' score was 2 standard deviations from the mean, so his z-score was 2.0. You can either use the empirical 68-95-98.5 rule, or you can plug it into your calculator as normalcdf(-999, 2) = .977

So 97.7% of people had a score lower than Carlos!

.977 * 1.5 million = 1,465,500 people

To find the total amount of money in the account at the end of 8 years with simple interest , we can use the formula:

A = P * (1 + r * t

where A = total amount P = principal (initial amount) r = interest rate per year (as a decimal) t = time (in years)

In this case, P = $300 r = 6.5% = 0.065 t = 8 years

Substituting these values in the formula:

A = $300 * (1 + 0.065 * 8) A = $300 * 1.52 A = $456

Therefore, the total amount of money in the account at the end of 8 years is $456 with simple interest.

Note that this assumes that the interest is compounded annually , and that there are no other deposits or withdrawals made during the 8-year period. If the interest is compounded more frequently, or if there are additional deposits or withdrawals, the calculation would be different.
