The probability that the first song is by Cardi B and the second song is by Taylor Swift is 1/24.

To calculate the probability of the first song being by Cardi B and the second song being by Taylor Swift, we need to consider the total number of possible outcomes and the number of favorable outcomes.

There are four songs in total, and we want to determine the probability that the first song is by Cardi B and the second song is by Taylor Swift. Since the order matters (the first song and then the second song), we can use the concept of permutations.

The total number of possible outcomes is the number of ways to arrange four songs, which is 4!.

The number of favorable outcomes is the number of ways to arrange the songs such that the first song is by Cardi B and the second song is by Taylor Swift. Since each song can only be played once, there are 1 way to choose Cardi B as the first song and 1 way to choose Taylor Swift as the second song.

The probability can be calculated as:

Probability = Number of favorable outcomes / Total number of possible outcomes

= 1 / 4!

Simplifying:

4! = 4 x 3 x 2 x 1 = 24

Probability = 1 / 24

The probability that the first song is by Cardi B and the second song is by Taylor Swift is 1/24.

Step-by-step explanation:

The food intake is proportional to body surface area. So, a 40 kg dog should eat 4.85 liters of dog food per week. Therefore, the correct answer is option a. 5 litres.

Since food intake is proportional to body surface area, we calculate the amount of food required for a 40 kg dog as:

(food for 10 kg dog) x (surface area of 40 kg dog) / (surface area of 10 kg dog)

To calculate the surface area, we can use the formula for the surface area of a sphere, which is 4πr^2, where r is the radius of the sphere. We can assume that the dogs are roughly spherical, so we can use their weight to estimate their radius using the formula:

radius = (weight / density)^(1/3)

where the density of a dog is approximately 1 g/cm^3.

For the 10 kg dog:

radius = (10,000 g / 1 g/cm^3)^(1/3) = 21.54 cm

surface area = 4π(21.54 cm)^2 = 5823.47 cm^2

For the 40 kg dog:

radius = (40,000 g / 1 g/cm^3)^(1/3) = 33.60 cm

surface area = 4π(33.60 cm)^2 = 14122.57 cm^2

Now we can plug in the values and solve for the amount of food required for the 40 kg dog:

(food for 10 kg dog) x (surface area of 40 kg dog) / (surface area of 10 kg dog) = (2 liters) x (14122.57 cm^2) / (5823.47 cm^2)

= 4.85 liters

Therefore, a 40 kg dog should eat about 4.85 liters of dry dog food per week, which is closest to 5 liters.

We would use 3 degrees of freedom when looking up the critical chi-square value.

When conducting a chi-square test with four categories and 16 subjects, we would use 3 degrees of freedom. This is because the degrees of freedom for a chi-square test with k categories and n subjects is calculated as (k-1)(n-1). In this case, (4-1)(16-1) = 3(15) = 45.

To calculate the degrees of freedom for a chi-square test in this scenario, you can use the formula:

Degrees of Freedom = (number of rows - 1) * (number of columns - 1)

In this case, we have 1 row for the subjects and 4 columns for the fast-food restaurant options. Plugging in the values, we get:

Degrees of Freedom = (1 - 1) * (4 - 1) = 0 * 3 = 0

Since there is only one row, the degree of freedom is 0. However, it's important to note that a chi-square test may not be appropriate for this situation, as it requires at least two rows to compare the observed frequencies to the expected frequencies.

Answer:

C=$7650

Step-by-step explanation:

Flat fee of 4500

S= 225x

x=14 tons of sugar

4500+225(14)=$7650 (C)

Equation:

C=4500+225(S)

Answer:

Total cost to transport 14 tons of sugar: $7650

Step-by-step explanation:

In the problem we are trying to find, C, the total cost to transport 14 tons of sugar.

$4500 to rent trucks

Additional $225 for each ton of sugar transported

C=4500+225(S)

We have our equation so now when begin to solve.

The problem gives us, S, the number of tons of sugar we are transporting, which is 14 tons.

So if it is an additional $225 for each ton of sugar then we would multiply 225 and 14. Which will look something like this:

C=4500+225(14)

Now we just simplify!

225(14)=3150

C=4500+3150

C=7650

a) The central 95% of all copper contents would be bounded by the values of 26.02 and 35.58.

b) The distribution of the sample mean copper content follows an approximately normal distribution with a mean of 30.8 and a standard error of \($\frac{2.45}{\sqrt{16}}\) =0.6125.

c) If we were to randomly sample 16 brake pads from this distribution, the bounding values for the central 95% of possible means would be (29.6, 32)

a) Since the copper content in sintered brake pads follows an approximately normal distribution with a mean of 30.8 and a standard deviation of 2.45, we can use the standard normal distribution to find the values that bound the central 95% of all copper contents. The 95% confidence interval corresponds to z=1.96 in the standard normal distribution. Thus, the values that bound the central 95% of all copper contents are given by:

30.8−1.96×2.45=26.02,30.8+1.96×2.45=35.58

b) The sample mean of copper content for a sample of 16 pads is also normally distributed with a mean of 30.8 and a standard deviation of \($\frac{2.45}{\sqrt{16}}=0.6125$\), which is called the standard error. The distribution of the sample mean is given by:

c) The bounding values for the central 95% of possible means can be found by using the formula:

where \($\sigma$\) is the population standard deviation, n is the sample size and \($z^*$\)is the critical value of the standard normal distribution that corresponds to a 95% confidence interval. Substituting the values, we get:

Therefore, the bounding values for the central 95% of possible means are given by:

Answer:

A = 1024 pi  units^2

Step-by-step explanation:

If r = 32 units, we can find the area

A = pi r^2

A = pi ( 32) ^2

A = 1024 pi  units^2

The area of the circle C is 1024π square units.

Area is the amount of space occupied by a two-dimensional figure.

The formula for the area of circle is given by

\(Area = \pi r^{2}\)

Where,

r is the radius of the circle

According to the question.

We have the radius of circle, r = 32 units

Therefore,

The area of the circle C is given by

\(Area = \pi (32)^{2}\)

⇒ \(Area = 1024\pi\) square units

Hence, the area of the circle C is 1024π square units.

The slopes of both those lines are the same so there is no solution. Use slope triangles to find out the slope. They are both 1/4.

A. No solution

y = 1/4x+5

x - 4y = 4

You can simplify the second equation into y = 1/4x - 1

Since these equations both have the same slope, they are parallel. When two lines are parallel, they have no solutions.

Each of the tables is classified as linear or non-linear on the image presented at the end of the answer.

A function is classified as linear or non-linear depending on the rate of change of the function.

If the rate of change of the function is constant, that is, when x changes by one amount, y always changes by the same amount, then the function is classified as linear.

Conversely, if the rate of change of the function is different for different intervals, then the function is classified as non-linear.

For example, the top-left function is non linear, as when x changes by one from x = 1 to x = 2, y changes by 3, from y = 1 to y = 4, while when x changes by one from x = 2 to x = 3, y changes by 5.

The bottom-right function is linear, as for each increase of x by 5, the value of y decays by 4.
