In a standard set of cards, the probability of drawing a red card or a face card is  73%

In a standard deck of cards, there are 26 red cards. In that same deck, there will be 12 face cards.

The probability of picking either one is:

= (Number of face cards + Number of red cards) / Number of total cards

Solving gives:

= (12 + 26) / 52

= 38 / 52

= 73%

Answer:

Step-by-step explanation:

Given function is,

\(f(x)=\frac{2x^2+6x}{-4x^2+8x}\)

       \(=\frac{2x(x+3)}{-4x(x-2)}\)

This function is not defined at "x(x - 2) = 0"

Therefore, for the values of x = 0 and 2, given function is not defined.

Vertical asymptote → x = 2 [Denominator = 0]

For Horizontal asymptote → \([\frac{2x^2}{-4x^2} =-\frac{1}{2}]\)

Therefore, horizontal asymptote → y = \(-\frac{1}{2}\)

x-intercept,

For f(x) = 0,

Numerator of the function = 0

2x² + 6x = 0

2x(x + 3) = 0

x = -3

Therefore, x - intercept → (-3, 0)

For y-intercept,

x = 0

f(0) = 0

Therefore, graph has no y-intercept.

For holes on the graph,

Since, function is not defined at x = 0,

f(x) = \(\frac{(x+3)}{-2(x-2)}\)

f(0) = \(\frac{(0+3)}{-2(0-2)}\)

     = \(\frac{3}{4}\)

Therefore, hole on the graph → \((0, \frac{3}{4})\)

If 6 tens are taken away from 950, we would have 9 hundreds and 9 tens.

To understand how many hundreds and tens we get when 6 tens are taken away from 950, let's break down the number.

The given number is 950. We can see that it consists of 9 hundreds and 5 tens. In other words, we have 9 sets of 100 and 5 sets of 10.

Now, if we take away 6 tens from this number, we subtract 6 from the original 5 tens. Since we cannot subtract 6 from 5, we need to borrow 1 hundred, which is equivalent to 10 tens, from the hundreds place.

So, we have 9 hundreds - 1 hundred = 8 hundreds. And we have 15 tens - 6 tens = 9 tens.

Therefore, when 6 tens are taken away from 950, we would have 8 hundred and 9 tens.

Range: All real numbers greater than or equal to 3. The Option C.

To find the range of the function, we need to determine the set of all possible y-values that the function takes.

Since the line crosses the y-axis at (0, 2), we know that the function's range includes the value 2. Also, since the line turns at (-1, 3), the function takes values greater than or equal to 3.

Therefore, the range of the function is all real numbers greater than or equal to 3.

a. The population being studied is the population of registered voters who will vote in the upcoming presidential election.

b. The sample being studied is the group of 850 registered voters who were surveyed by telephone.

c. Based on the sample, it is estimated that 45% of the population would vote for candidate B. However, it's important to note that this is only an estimate based on a sample of registered voters, and it may not accurately reflect the views of the entire population. Additionally, since the sample size is only 850, the estimate may have a margin of error associated with it. To get a more accurate estimate of the percentage of the population that would vote for candidate B, a larger sample size or a different method of polling would be necessary.

Width is \(1 \frac{1}{4} m\) or 1.25m

The triangle solve for B = 36°, a = 41, c = 20 is:

b ≈ 27.5, C ≈ 115.5, A ≈ 28.5

To solve the triangle, we can use the Law of Cosines, which states that for any triangle with sides a, b, and c and angles A, B, and C opposite those sides,

c² = a² + b² - 2ab cos(C)

We can use this formula to find the length of the missing side b:

b² = a² + c² - 2ac cos(B)

b² = 41² + 20² - 2(41)(20) cos(36°)

b² ≈ 1074.12

b ≈ 32.8

Now that we have found the length of side b, we can use the Law of Sines to find the measures of angles A and C:

sin(A) / a = sin(B) / b

sin(A) / 41 = sin(36°) / 32.8

sin(A) ≈ 0.274

A ≈ 16.5°

We know that the angles in a triangle add up to 180°, so C = 180° - A - B ≈ 127.5°.

The closest choice to these values is:

b ≈ 27.5, C ≈ 115.5, A ≈ 28.5

The Net profit margin is 22.41%

Rusty's Tool experienced $67550 in net sales, creating a gross profit of $50338.

If Rusty had a total operating expense of $35200 then we have to find the net profit margin.

Since profit $50338 includes the operating expense of $35300 then net profit will be

= $50338 - $33500

= $15138

Now the selling price is given as $67550.

Profit margin = (Net profit/selling price) 100

Profit margin =151.38/675.50=22.41 %

The probability of 2 customers in the system is 0.1418.

In order to find the probability of 2 customers in the system, the M/M/1 queuing model is to be applied.

M/M/1 model is a single-server queue model that assumes a Poisson arrival pattern and an exponential service pattern.

The service time is exponential and has a mean of 5 minutes.

Let's start calculating the values for the M/M/1 model:

For arrival rate, λ = 7 customers per hour

For service rate, μ = 12 customers per hour

The utilization factor can be determined using the following formula:ρ = λ/μ = 7/12

                                                                                                                               = 0.5833

The probability of 2 customers in the system can be found using the following formula:

P2 = (1 - ρ)(ρ)2= (1 - 0.5833)(0.5833)2

     = 0.1418

Therefore, the probability of 2 customers in the system is option B, i.e., 0.1418.

horizontal scale.

It is defined as the process of adding more instances of the same type to the existing pool of resources and not

increasing the capacity of existing resources like in vertical scaling. This kind of scaling also helps in decreasing the

load on the server. This is called Horizontal Scaling

Answer:

8(x + 6) = 144

Step-by-step explanation:

We can start building this equation by making everything equal to 144 since the problem is representing the total number of apples:

? = 144

Next, we don't know how many apples are in each basket, so we can represent it with a variable, x.

Since 6 apples are added to each basket we will simply add 6 to the "x" amount of apples in each basket:

x + 6 = 144

Lastly, according to the scenario, we have 8 baskets, each holding "x" amount of apples plus the extra 6 that was added, so it will be multiplied:

8(x + 6) = 144
