The probability of the value of p(a ∩ bc ) is 1/54

Probability is a mathematical measure of how likely an event is to occur.

Given that p(a ∪ b) = 2/3, which means the probability of either event a or event b happening is 2/3, we can find the probability of a and b happening simultaneously using the formula for conditional probability.

=> p(a ∩ b) = p(a | b) * p(b) = 1/12,

where p(a | b) is the probability of event a happening given that event b has already happened. We can use this information to find p(b) as follows:

=> p(b) = p(a ∩ b) / p(a | b) = 1/12 / p(a | b)

We also know that p(b ∩ ac) = 1/3, which means the probability of both events b and ac happening is 1/3. We can use this information to find p(b) and p(a | b).

=> p(b) = p(b ∩ ac) / p(ac | b) = 1/3 / p(ac | b)

Finally, using the formula for conditional probability, we can find p(a ∩ bc) as follows:

p(a ∩ bc) = p(a | bc) * p(bc) = p(a | b) * p(b | bc) * p(bc) = p(a | b) * p(b) * p(bc | b) * p(bc)

p(a ∩ bc) = 2/3 * 1/12 *1/3 = 1/54

Answer:

3 r 2

Step-by-step explanation:

Do 3 times 1 which equals 3

Then do 3 times 2 which equals 6

Then do 3 times 3 which equals 9

But if you do 3 times 4 it will equal 12 so you can't do that.

Therefore, it will be 3 and then you do 11-9 which equals 2 so there is your remainder.

Answer is 3 r2

The surface areas of the given cylinders are 94.5 in²,150.72 in², 100.48 in², 200.96 in² and 314 in²

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.

Given are cylinders, we need to find the surface area of them,

The surface area of a cylinder  = 2πr(h+r), where r and h are radius and height of the cylinder,

1) Height = 2 in and radius = 3 in

Surface area = 2·3.14·3·(3+2) = 94.5 in²

2) Height = 5 in and radius = 3 in

Surface area = 2·3.14·3(5+3) = 150.72 in²

3) Height = 6 in and radius = 2 in

Surface area = 2·3.14·2(6+2) = 100.48 in²

4) Height = 4 in and radius = 4 in

Surface area = 2·3.14·4(4+4) = 200.96 in²

5) Height = 4 in and radius = 4 in

Surface area = 2·3.14·5(5+5) = 314 in²

Hence, the surface areas of the given cylinders are 94.5 in²,150.72 in², 100.48 in², 200.96 in² and 314 in²

The number of bags of flour would be 40.

And, the number of bags of sugar would be 120.

Given that,

You must buy three times as many bags of sugar as there are bags of flour.

And, you are on a budget of $720. Flour costs $6 per bag and sugar costs $4 per bag.

Let us assume that,

The number of bags of flour = x

And, the number of bags of sugar = y

Hence, we get;

y = 3x  .. (i)

And, 6x + 4y = 720  .. (ii)

Substitute x = 3y in (ii);

6x + 4 (3x) = 720

6x + 12x = 720

18x = 720

x = 720/18

x = 40

From (i);

y = 3 × 40

y = 120

Thus, The number of bags of flour = 40

And, the number of bags of sugar = 120

Answer:

⇛(5+√2)/23.

Step-by-step explanation:

Given,

1/(5-√2)

The denominator is 5-√2.

We know that

The rationalising factor of a+√b is a-√b.

Therefore, the rationalising factor of 5-√2 is 5+√2. To rationalise the denominator is 1/(5-√2), we multiply this by (5+√2)/(5+√2).

∴ 1/(5-√2)

= {1/(5-√2)}×{(5+√2)/(5+√2)}

= {1(5+√2)}/{(5)²-(√2)²} [∵(a-b)(a+b)=a²-b²]

= {1(5+√2)}/{(5*5)-(√2*2)}

= {1(5+√2)}/25 - 2

= {1(5+√2)}/23

= (5+√2)/23

Hence the denominator is rationalised.

The distribution of the data is skewed right, which means that the data is not evenly distributed across the range of values.

To calculate the skewness, we can use the formula Skewness = (Mean - Mode) / Standard Deviation. In this case, the mean is 599.2 seconds, the mode is 590 seconds, and the standard deviation is 110.88 seconds. Plugging these values into the formula, we get Skewness = (599.2 - 590) / 110.88 = 0.8094. This indicates that the data is skewed right, as the skewness is greater than 0. A right-skewed distribution typically occurs when the majority of data points are closer to the minimum value, while there are fewer data points near the maximum value. This can be seen in the graphical summary, where the majority of the data points are clustered around the lower end of the range and the tail extends to the right.

Step-by-step explanation:

The value of \(f^{-1}(x)\) is \(\frac{x}{\sqrt[3]{2} }\)  when f(x) = 16  is \(x=2^\frac{11}{3}\) .

We have given a function \(f(x)=x\sqrt[3]{2}\).        ....(1)

 Let y = f(x)

         \(y=x\sqrt[3]{2} \\\\x=\frac{y}{\sqrt[3]{2} }\)                         ......(2)

Swap the values of x and y, then the inverse is then

Answer:

small triangle area = 1/2(8)(14) = 56 m²

bigger triangle area = 1/2(16)(14) = 112 m²

biggest triangle area = 1/2(24)(14) = 168 m²

there's 2 bigger triangles so you pick the bigger one you want

Answer:

smaller triangle area = 56m²

larger triangle area = 112m²

total area = 168m²

Step-by-step explanation:

Area of triangle = \(\frac{bh}{2}\)

where b = base length and h = height

smaller triangle dimensions

base length= 8m

height = 14m

* plug in the values into the formula *

\(area=\frac{8*14}{2} \\8*14 =112\\\frac{112}{2}=56\\A=56m^2\)

so we can conclude that the area of the smaller triangle is 56 square meters

larger triangle dimensions

base length = 16m

height = 14m

* plug in the values into the formula *

\(area=\frac{16*14}{2} \\16*14=224\\\frac{224}{2} =112\\A=112m^2\)

so we can conclude that the area of the larger triangle is 112 square meters

total area = the sum of the two triangle's area

total area = 112 + 56

112 + 56 = 168

hence the total area is 168 square meters

Answer:

B. \(k(x)=(-x+3)^{1/2}\)

Step-by-step explanation:

When we're talking about a restricted domain, we're looking for a function that's undefined for certain values of x. A classic example is the function f(x) = 1/x. Division by 0 is undefined, so this restricts our domain to all real numbers except 0.

A key feature of our problem is in the exponents - are there any exponents that would limit the possible values of x? Let's strip away the rest of the details and just look at those powers for each option:

For A, let's look at the function \(f(x) = x^{1/5}\). Remember that fractional exponents are the same as roots, so we could also say \(f(x)=\sqrt[5]{x}\). Any odd root like this can take any value for x, positive and negative. This has to do with the fact that any odd power of a negative is always negative. So no restrictions on A.

For B, just looking at the exponent, let's see if there are restrictions on the function \(k(x) = x^{1/2}\). Again, we can rewrite the right side as a root: \(k(x) = \sqrt{x}\).

Unline f(x), k(x) is restricted. The square root of a negative number has no real solutions, so k(x) comes with the restriction that x ≥ 0. We could look at C and D, but we've already found our solution at this point, so I'll stop here!

The probabilities of picking an A, a B or a C is given as follows:

167/210.

A probability is obtained by the division of the number of desired outcomes by the number of total outcomes in the context of a problem.

For each event, the probabilities in this problem are given as follows:

To find the or probability, we add the probabilities of the desired outcomes, hence:

P(A) + P(B) + P(C) = 1/5 + 3/7 + 1/6 = (42 + 90 + 35)/210 = 167/210.

the criteria used when deciding upon the inclusion of a variable are A - Theory, B - t-statistic, C - Bias, and D - Adjusted R^2.

When deciding upon the inclusion of a variable, the following criteria are commonly used:

A - Theory: Theoretical justification is often considered to include a variable in a model. It involves assessing whether the variable is relevant and aligns with the underlying theory or conceptual framework.

B - t-statistic: The t-statistic is used to determine the statistical significance of a variable. A variable with a significant t-statistic suggests that it has a meaningful relationship with the dependent variable and may be included in the model.

C - Bias: Bias refers to the presence of systematic errors in the estimation of model parameters. It is important to consider the potential bias introduced by including or excluding a variable and assess whether it aligns with the research objectives.

D - Adjusted R^2: Adjusted R^2 is a measure of the goodness of fit of a regression model. It considers the trade-off between the number of variables included and the overall fit of the model. Adjusted R^2 helps in assessing whether the inclusion of a variable improves the model's explanatory power.
