The probability of getting a diamond or a king from a standard 52-card deck is 4/13.

In mathematics, probability is a measure of the likelihood that an event will occur. It is a way to quantify the chances of different outcomes or events in a random experiment or process. Probability is typically expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event

In a standard deck of 52 cards, there are 13 diamonds and 4 kings. However, the king of diamonds is also a diamond, so we must subtract one from the total count to avoid double-counting.

So there are 13 + 4 - 1 = 16 cards that are either diamonds or kings.

The probability of picking a diamond or a king is therefore 16/52.

Simplifying the fraction, we get:

16/52 = 4/13

Now we can calculate Tran’s dessert making rate:

152 desserts / 10 months = 15.2 desserts per month

So Tran’s dessert making rate is 15.2 desserts per month.

Step-by-step explanation:

Answer: The given expression can be factorized as (2k - 3)(k² - 1) using the difference between squares.

Step-by-step explanation: To factorize the given expression using the difference between squares, we need to identify terms that can be written as the square of some other term.

We can rewrite the expression as:

(2k³ - 3k²) - (2k - 3)

Now, we can factor out the common terms from each bracket:

k²(2k - 3) - 1(2k - 3)

We can see that both brackets have a common factor of (2k - 3), which we can factor out:

(2k - 3)(k² - 1)

Therefore, the given expression can be factorized as (2k - 3)(k² - 1) using the difference between squares.

As per the mentioned informations, the probability that x has a value of at least 95 is calculated to be 0.2 or 20%.

Since x is uniformly distributed between 75 and 100, the probability density function (PDF) of x is given by:

f(x) = 1/(100-75) = 1/25 for 75 ≤ x ≤ 100

To find the probability that x has a value between 80 and 90, we need to calculate the area under the curve between x = 80 and x = 90:

P(80 ≤ x ≤ 90) = ∫[from 80 to 90] f(x) dx

= ∫[from 80 to 90] 1/25 dx

= [1/25 × x] [from 80 to 90]

= (90-80)/25

= 0.4

Therefore, the probability that x has a value between 80 and 90 is 0.4 or 40%.

To find the probability that x has a value of at least 95, we need to calculate the area under the curve to the right of x = 95:

P(x ≥ 95) = ∫[from 95 to 100] f(x) dx

= ∫[from 95 to 100] 1/25 dx

= [1/25 × x] [from 95 to 100]

= (100-95)/25

= 0.2

Therefore, the probability that x has a value of at least 95 is 0.2 or 20%.

At the end of the additional 20-minute period, there are approximately 18.71 pounds of salt in the tank.

Let's denote the amount of salt in the tank at any time t by Q(t), measured in pounds.

Initially, the tank contains 0 pounds of salt. Then, water containing 0.8 lb of salt per gallon is poured into the tank at a rate of 8 gal/min for 20 min, so the total amount of salt added to the tank during this time is

Q₁ = (0.8 lb/gal) × (8 gal/min) × (20 min) = 128 lb

The total volume of water in the tank after 20 minutes is

V₁ = 100 gal + (8 gal/min) × (20 min) = 260 gal

So the concentration of salt in the tank at this point is

C1 = Q₁ / V₁ = 128 lb / 260 gal = 0.4923 lb/gal

During the next 20 minutes, fresh water is poured into the tank at a rate of 8 gal/min, and the mixture is allowed to leave at the same rate. Since the tank initially contains 260 gallons of water, and 8 gallons are leaving every minute, we can see that the total volume of water in the tank during this time is

V₂ = 260 gal - (8 gal/min) × (20 min) = 100 gal

This means that the tank is back to its initial volume of 100 gallons, and all the water in it is fresh. However, there is still some salt left in the tank. We need to find the amount of salt Q₂ in the tank at the end of this period.

During the second 20-minute period, no salt is added to the tank, so the amount of salt in the tank is decreasing only due to the outflow of the mixture. We can use the formula

Q(t) = Q₀ × [tex]e^{-kt}[/tex]

where Q0 is the initial amount of salt (in our case, Q₁), k is the rate constant (which we need to find), and t is the time. We know that Q(20) = Q1 × [tex]e^{-k20}[/tex] is the amount of salt in the tank at the end of the first 20 minutes, and we want to find Q(40), the amount of salt in the tank at the end of the second 20-minute period.

To find k, we can use the fact that the concentration of salt in the tank is decreasing at a rate of 0.8 lb/gal × 8 gal/min = 6.4 lb/min, which means that

dQ/dt = -C₁ × 8 gal/min = -3.14 lb/min

We can write this as

dQ/dt = -k × Q(t)

Substituting Q(t) = Q₁ × [tex]e^{-kt}[/tex] and C₁ = Q₁ / V₁, we get:

-k × Q₁ ×  [tex]e^{-kt}[/tex]  = -Q₁ × C₁ × 8 gal/min

Simplifying:

k = 0.0300

Now we can find Q(40) as

Q(40) = Q₁ × [tex]e^{-k40}[/tex] = 18.71 lb

Comparing the z-scores, a score of 94 on a test with a mean of 72 and a standard deviation of 11 is relatively better than a score of 687 on a test with a mean of 447 and a standard deviation of 150, as the z-score of the first test (2) is higher than the z-score of the second test (1.6).

To determine which score is relatively better, we will calculate the z-scores for both test results using the given mean and standard deviation values. A z-score represents how many standard deviations a data point is away from the mean. The higher the z-score, the better the performance relative to the mean.

For the first test:
1. Subtract the mean (72) from the score (94): 94 - 72 = 22
2. Divide the difference (22) by the standard deviation (11): 22 / 11 = 2

The z-score for the first test is 2.

For the second test:
1. Subtract the mean (447) from the score (687): 687 - 447 = 240
2. Divide the difference (240) by the standard deviation (150): 240 / 150 = 1.6

The z-score for the second test is 1.6.

Equation is a mathematical statement that two expressions are equal. It is written as an expression that shows the equality of two values using mathematical symbols. Equations are used to solve problems by finding the unknown value. They are used in almost all branches of mathematics, and help to explain the behavior of physical and chemical systems.

The equation of a parabola with vertex (x_0,y_0) and that passes through (x_1,y_1) can be expressed as

y = a(x - x_0)^2 + y_0

where a is a constant.

In this case, the vertex of the parabola is (-2, 5) and it passes through (4, -8). We can substitute these values for x_0, y_0 and x_1, y_1 into the equation to get:

y = a(x - (-2))^2 + 5

We can solve for a by substituting the coordinates of the given point (4, -8) into the equation:

-8 = a(4 - (-2))^2 + 5

-8 = a(6)^2 + 5

-8 = 36a + 5

Given information:

Two stores each advertise a discount on the same type of hat at both stores.

The original price of the hat was $45 store A discounted the price of the hat by 25% store B discounted the price of the hat by 15%.

The discount at store A is 25% off $45, which is $11.25. So the discounted price at store A is $33.75 ($45 - $11.25).

The discount at store B is 15% of $45, which is $6.75. So the discounted price at store B is $38.25 ($45 - $6.75).

The difference between the discounted price at store A and store B is $38.25 - $33.75 = $4.50.

The group which completes the given work in 13 days is Group A with members of P, Q, and R.

Total number of men = 4

P, Q, R, S.

Let us consider that S takes 1 unit of time to complete the work.

Then, the time taken by each of the other men to complete the work as follows,

R takes 3 units of time to complete the work.

Q takes 9 units of time to complete the work.

P takes 27 units of time to complete the work.

Let the group that completes the work in 13 days be called Group A.

and the group that completes the work in 31 days be called Group B.

Let us assume that Group A consists of P, Q, and R,

Group B consists of S, Q, and R.

Group C consists of P, Q, S.

The total work done by the two groups is the same.

Let us consider that the total work is 1 unit.

Then, the amount of work done by Group A in 1 day is,

=   1/((1/27)+(1/9)+(1/3))

= 1/((1 + 3 + 9 )/ 27)

= 27/13

The amount of work done by Group B in 1 day is,

= 1/((1/1)+(1/9)+(1/3))

= 1/((9+3+1)/9)

= 9/13

The amount of work done by Group C in 1 day is,

=  1/((1/27)+(1/9)+(1/1))

= 1/((1 + 3 + 27 )/ 27)

= 27/31

Group A completes 27/13 units of work in 1 day.

Group B completes 9/13  is equivalent to 27 / 39 units of work in 1 day.

and Group C complete 27/31 units of work in 1 day.

If we consider 27 as one unit.

Then Group A completes the work in 13 days.

And Group C completes the work in 31 days.
