a. The probability of a rap song being played is 9/25 or 0.36 (36%).

b. The probability of a song not being country is 19/25 or 0.76 (76%).

a) To find the probability that a randomly played song is a rap song, we need to consider the total number of songs and the number of rap songs.

There are 10 rock songs, 9 rap songs, and 6 country songs, for a total of 25 songs.

The probability of a rap song being played is:
(Number of rap songs) / (Total number of songs) = 9 / 25.
So, the probability of a rap song being played is 9/25 or 0.36 (36%).
b) To find the probability that a randomly played song is not country, we need to consider the total number of songs and the number of songs that are not country.

Since there are 6 country songs out of the 25 total songs, there are 19 songs that are not country (10 rock + 9 rap).

The probability of a non-country song being played is:
(Number of non-country songs) / (Total number of songs) = 19 / 25.

Answer:

a = \(\frac{1}{2}\) , b = 5, and  \(\frac{2b}{a}\) = 20

Step-by-step explanation:

f(x) = - x² + b, x ≤ 0     You would use this equation for f(-2). Since -2 is less than 0.

f(x) = - x² + b, x ≤ 0   ← You can ignore the x ≤ 0 part.

f(-2) = - (-2)² + b         Input the value -2 as x. The question states that f(-2) =1.

1 = - (-2)² + b              So switch f(-2) with 1 on the left side only.

1 = - (4) + b                Simplify. Do the exponents first, so (-2)² = 4.

1 = - 4 + b

+4  +4                      Do inverse operations

5 = b

Next,

f(x) = 2ax +3, x > 0      You would use his equation for f(2). Since 2 is greater than 0.

f(x) = 2ax +3, x > 0   ← You can ignore the x > 0 part.

f(2) = 2a(2) + 3             Input the value 2 as x.

f(2) = 4a +3           Simplify. The equation states f(2) = 5. So switch f(2) with 5

5 = 4a +3              on the left side only.

-3        - 3                     Do inverse operations

2 = 4a                          

\(\frac{2}{4}\) = \(\frac{4a}{4}\)                           Divide 4 on both sides to isolate the variable a

\(\frac{2}{4}\) = a                            Simplify

\(\frac{1}{2}\) = a

Then,

The second part says to find \(\frac{2b}{a}\)

\(\frac{2b}{a}\)

\(\frac{2(5)}{(\frac{1}{2}) }\)                  Input both the values of a and b

\(\frac{10}{\frac{1}{2} }\)                    Simplify

20.

The answer for a is \(\frac{1}{2}\), the answer for b is 5, and the answer for \(\frac{2b}{a}\) is 20.

The correct answer is: A)  on his particular test, John did better on his test.

To determine which student performed relatively better on their respective test, we need to compare their scores in relation to the mean and standard deviation of their respective tests.

For John, his score of 113 is above the mean of 100 and deviates by (113 - 100) / 10 = 1.3 standard deviations from the mean.

For Brandon, his score of 263 is above the mean of 250 and deviates by (263 - 250) / 25 = 0.52 standard deviations from the mean.

Since John's deviation from the mean is larger than Brandon's, we can conclude that John performed relatively better on his particular test.

Answer:

C

Step-by-step explanation:

y=5x reads "y equals (5 times x)", which we can rephrase to "the value of y is 5 times the value of x"

y=x+5 reads "y equals (x plus 5)", which we can rephrase to "the value of y is 5 more than the value of x".

Ergo, answer C is what we're looking for.

Answer: C

Step-by-step explanation:

in y=5x, we can see a 5 placed in front of x. If there is no addition, subtraction, or division sign between a number and a variable, it always means it's multiplication.

We know now that this is 5 times x.

In y=x+5, we see that 5 is being added to x. Therefore, y is 5 more than x.

So there you have it.

The technique for determining an array index using only a search key and not searching is called hashing.

Hashing is a method that maps data to a fixed-size array called a hash table. In this technique, a hash function is used to generate a unique index for each search key. The hash function takes the search key as input and performs some calculations to produce the index value.

This index is then used to access the corresponding element in the array, providing direct access to the desired data without the need for further searching.

Step-by-step explanation:

The original slope's reciprocal will be the opposite of the perpendicular slope. To determine the intercept, b, enter the supplied point and the new slope into the slope-intercept form (y = mx + b). Rewrite the following equation in standard form: ax + by = c.

The values of the slope and y-intercept provide details on the relationship between the two variables, x and y. The slope shows how quickly y changes for every unit change in x. When the x-value is 0, the y-intercept shows the y-value.

Y = mx + b, where m denotes the slope and b the y-intercept, is how the equation of the line is expressed in the slope-intercept form. We can see that the slope of the line in our equation, y = 6x + 2, is 6.

The slope is m and the y-intercept is b in the equation y=mx+b in slope-intercept form. Some equations can also be rewritten so that they resemble slope-intercept form. For instance, y=x can be written as y=1x+0, resulting in a slope and y-intercept of 1 and 0, respectively.

42.3 x 100=4230

Answer:If p and q vary inversely, it means that their product remains constant. So we can set up the equation:

p * q = k

where k is the constant of variation.

Given that p is 29 when q is 25, we can substitute these values into the equation:

29 * 25 = k

725 = k

Now, let's determine the value of q when p is equal to 5:

p * q = k

5 * q = 725

Dividing both sides of the equation by 5:

q = 725 / 5

q = 145

Therefore, when p is equal to 5, q is equal to 145.

Step-by-step explanation:

Answer:p1q1=p2q2

q1=25,p1=29;

p2=5,q2=?;

q2=p1q1/p2;

q2=25*29/5;

The letter has reflection symmetry only. When one half of an object or form reflects the other half, this is known as reflection symmetry. The line where you cut is referred to as the line of symmetry, generating the two equal portions, and the two halves are reflections of one another.

Mirror symmetry, line symmetry, reflection symmetry, and mirror-image symmetry are all terms used in mathematics to describe symmetry with respect to a reflection. To put it another way, a figure with reflectional symmetry is unaffected by reflection. There is a symmetry line or axis in 2D and a symmetry plane in 3D.

A sort of symmetry that pertains to reflections is called reflection symmetry. Line symmetry and mirror symmetry are other names for reflection symmetry. If a figure has at least one line dividing it into two halves, one half is said to be the mirror image of the other half.

If the constraint Q1 + Q2 ≥ 30 is relaxed by one unit, the total cost will increase by λ = 4.

The given objective function is TC=4Q1²+5Q2²−Q1Q2, which we need to minimize subject to the constraint Q1+Q2≥30 using the Lagrangian method. Let's begin the Lagrangian method solution as follows;

L(Q1,Q2,λ)= TC + λ(30 - Q1 - Q2)

Where λ is the Lagrange multiplier

1: Calculate the partial derivatives of L with respect to Q1, Q2, and λ and set them equal to zero

∂L/∂Q1 = 8Q1 - Q2 - λ = 0 .......(1)

∂L/∂Q2 = 10Q2 - Q1 - λ = 0 .......(2)

∂L/∂λ = 30 - Q1 - Q2 = 0 .......(3)

2: Solve the above three equations for Q1, Q2, and λ using the elimination method. Eliminate λ by adding equations (1) and (2). Then substitute this λ value in the third equation. Simplify the equation and solve for Q1 and Q2.

Q1 = 6 and Q2 = 24

λ = 4

The optimal values of Q1 and Q2 are 6 and 24 respectively. The value of lambda is 4.

The value of λ represents the marginal cost of relaxing the constraint by one unit. Intuitively, lambda represents the shadow price of the constraint, i.e., the amount by which the objective function value will increase if the constraint is relaxed by one unit.

Since these two events are independent, multiply the two probabilities together:

6*11 = 66 (choices)

Alex can make a total of 180 different sandwiches by choosing one kind of meat from 10 options and two kinds of cheese from 9 options.

To determine the number of different sandwiches Alex can make, we need to consider the combinations of meat and cheese. Since Alex can choose one kind of meat from 10 options, there are 10 choices for the meat component of the sandwich. For the cheese component, Alex can choose two kinds of cheese from 9 options.

To calculate the total number of combinations, we can use the formula for combinations without repetition. The formula is nCr = n! / (r!(n-r)!), where n is the total number of options and r is the number of choices. In this case, n is 9 (number of cheese options) and r is 2 (number of cheese choices). Thus, the number of combinations of two kinds of cheese is \(9C2\)= 9! / (2!(9-2)!) = 36.
