We can say that he used a total of 5/8 gallons of glue

let x - glue to make purple slime

5/8 = 2/5 + 1/5 + x

5/8 = 3/5 + x             (LCD of 5 and 8 is 40)

25/40 = 24/40 + x

25/40 - 24/40 = 24/40 - 24/40 + x    (subtract 24/40 both sides)

x = 1/40

5/8 = 2/5 + 1/5 + 1/40

5/8 = 3/5 + 1/40

25/40 = 24/40 + 1/40

25/40 = 25/40

Therefore, the glue to make purple slime is 1/40 gallons.

As a result, the likelihood of a flush (five cards of the same suit) is.198% while the likelihood of getting three cards of the same rank and two cards from any other rank is 0.07612%.

Probability is the study of numerical representations of the likelihood that an event will happen or that a statement is true. An event's probability is a number between 0 and 1, where 0 generally denotes the event's impossibility and 1 typically denotes its certainty.

Here,

a) It is irrelevant what suit the opening card is. Any of the suits may be drawn first, provided that the subsequent four cards are dealt from the same deck and are of the same suit.

After the initial card is drawn, there are only 12 of a given suit left in the deck, which has 13 of each suit in total. The third card, which has 11, the fourth card, which has 10, and the fifth and final card, which has nine, are then the cards that are still available. Each time, one fewer card will be present in the deck as a whole.

(ℎ) = (2 ) ∙ (3 ) ∙ (4ℎ )\s∙ (5ℎ )

(ℎ) = [tex]\frac{12}{51} *\frac{11}{50} *\frac{10}{49} *\frac{9}{48}[/tex]

(ℎ) =11880 / 5997600

(ℎ)= 33/16660 = .00198 .198%

c) The likelihood of three identical cards and two cards from one other rank.

Considering that the cards have 13 ranks

So, P =  [tex]\frac{13}{52} *\frac{12}{51} *\frac{11}{50} *\frac{10}{49}[/tex]

P = 267696/351655200

P=0 .0007612 or 0.07612 %

As a result, the likelihood of a flush (five cards of the same suit) is.198% while the likelihood of getting three cards of the same rank and two cards from any other rank is 0.07612%.

The operations are solved applying the inverse operations.

The first operation is solved as follows:

x + 10 = 25

x = 25 - 10

x = 15.

Hence the addition operation was solved applying the subtraction operation, which is the inverse operation of the addition.

The second operation is solved as follows:

2x = 28

x = 28/2

x = 14.

Hence the multiplication operation was solved applying the division operation, which is the inverse operation of the multiplication.

The third operation is given as follows:

4^x = 64.

log4(4^x) = log4(64)

The null hypothesis in the given question is 'the mean annual consumption of high fructose corn syrup by a person in the United States is 48.8 pounds' and the alternative hypothesis in the given question is 'the population standard deviation is 3.6 pounds.'

Population mean = 48.8 pounds

Sample size = 120

Sample mean = 49.5 pounds

Population standard deviation = 3.6

α = 0.05

The standardized statistic z is:

z = (Sample mean - Population mean) x (√n / standard deviation)

z = (49.5 - 48.8) x (√120/3.6)

z = 2.13

The standardized statistic P is:

Timmy has a collection of 95 coins consisting of dimes and nickels in his bank, The total value of his bank is $6.50. We can infer that he has 60 nickels and 35 dimes.

In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities.

Given,

Timmy has a collection of 95 coins consisting of dimes and nickels in his bank, The total value of his bank is $6.50.

Set d and n to the appropriate numbers.

Timmy has 95 coins in total, all of which are dimes and nickels, as far as we know.

Equation,

So d + n = 95

His bank is worth a total of $6.50.

A nickel is worth $0.05, while a dime is worth $0.10.

So

0.10d + 0.05n = $6.50

Take note that we have just produced an equation system that we can solve.

The two equations exist.

D + n = 95

and

0.10d + 0.05n = 6.50.

The replacement approach is probably going to be the simplest way to solve this problem out of all the options available to us.

First, we'll want to change the second equation's terms so that one of the variables is defined.

d+ n = 95

Take d off on both sides.

n = 95 - d

Now, let's define "n."

After defining one of the variables, we can now enter (or replace) its value in the other equation. After replacing it, we can find a solution for the other variable.

0.10d + 0.05n = 6.50

n = 95 - d

0.10d + 0.05(95 - d) = 6.50

We now determine d.

0.10d + 0.05(95 - d) = 6.50

distribution of the 0.05 in step 1

0.05 × 95 = 4.75

and

0.05 × -d = -0.05d

0.10d + 4.75 - 0.05d = 6.50

Step 2: Add like terms together (0.10 - 0.05) to get 0.05

0.05d + 4.75 = 6.50

step 3: Take 4.75 off of each side.

0.05d = 1.75

step 4: Subtract 0.05 from both sides.

0.05d / 0.05 = d and 1.75 / 0.05 = 35

d = 35

Now that we know the value of one variable, we can use it to solve for the second variable by plugging it into one of the equations ( note that the equation that we use does not matter, we will acquire the same answer )

d + n = 95

d = 35

35 + n = 95

Take 35 off both sides.

n = 60

We can infer that he has 60 nickels and 35 dimes.

Here, we are given the following statement-

For all sets A, B and C if A ≤ B and B∩C = Φ

then A∩C = Ф

We can use the proof-by-contradiction method to prove the given statement as shown below-

Suppose that there exist 3 sets, that are- A, B, and C

Such that A ≤ B, B∩C = Φ

and A∩C ≠ Φ

Then, there must exist an element x such that x ∈ A∩C

Now, by the definition of intersection, we have- x ∈ A and x ∈ C

Then x ∈ B because A ≤ B. Additionally, we know that x ∈ C

Hence, by the definition of intersection, x ∈ B∩C

Thus, B∩C ≠ Φ by definition of null set (Φ)

But this contradicts the supposition. Hence, our assumption is false and so A∩C = Ф.

A formal power series that encodes the coefficients of a sequence of numbers is a generating function.

Here, the coefficients of the sequence {Sₙ} are encoded by the generating function S(x). where Sₙ is the number of lattice paths as described above.

Here we will use the fact that the generating function for a sequence satisfies a functional equation that relates the generating function to the sequence itself to prove that 1 + (x – 1)S(x) + xS(x)² = 0,

Here, the functional equation is

S(x) = 1 + xS(x) + xS(x)²

This equation implies that

The term 1 on the right-hand side corresponds to the fact that to reach the point (0,0) (the starting point), there is exactly one way which is to stay at the starting point.

The term xS(x) corresponds to the fact that by taking a step in the positive x-direction and then following a path to (n-1, n-1) we can reach any point (n,n)

The term xS(x)² corresponds to the fact that by taking a step in the positive x-direction and then following a path to (n-2, n-2), and then taking another step in the positive x-direction and following a path to (n-1, n-1) we can reach any point (n,n)

To maximise the profit in a day, we maximize z = (6.50 x x) + (7.50 x y)

The maximum profit is obtained at (449.93,500.02).

Therefore, z = (6.50 x 449.93) + (7.50 x 500.02)

z = 2924.545 + 3750.15

z = 6674.695

The profit earned per day is $6674.695.

The length of the Arc of the circle is 17.00 units

We should know that the arc of the circle is part of the circumference of the circle cut off by the radii of the circle.

The length of the arc is given by

L=[tex]\frac{A}{360} *2*\pi *r[/tex]   where A= angle made by the radii

[tex]\pi[/tex]=3.14, radius =10, L-length of arc = x

Applying the values in the formula we have

x=(x/3*2*3.14*10)÷360

Simplifying the expression

62.8x=1080x

Taking the ratio of both sides we have

62.8x:1080x

= 17.00 units

Therefore the length of the arc is 17.00 units

In the graph B we can see that y intercept is 9 and zero is 3. So the graph b is the correct answer.

In the given question, linear function k has a zero at 3 and a y-intercept of 9.

We have to choose which graph best represents k.

As we know that;

The link between the two unknown variables is represented by a linear equation. The linear equation have one degree.

The most basic linear equation demonstrates the relationship between (x,y), which can be used to create a table, a graph on the coordinate plane, or to perform an assessment at a particular x or y value.

We represent linear function in the form of y=mx+c.

where m is the slope of the line, c is the y intercept of the line, x is independent variable and y is the dependent variable.

As we see the y intercept in the graph crosses the y axis.

Here y intercept is 9.

The zeros of the linear function is that where y value is zero.

As in the graph B we can see that y intercept is 9 and zero is 3. So the graph b is the correct answer.

Answer:

t ≥ 5

Step-by-step explanation:

In the tank now: 19

Fill rate per minute: 6

Number of minutes: t

Amount filled in t minutes: 6t

Total amount in tank after t minutes: 6t + 19

Amount desired: at least 49 liters

At least 49 liters means "greater than or equal to 49"

Inequality:

6t + 19 ≥ 49

Subtract 19 from both sides.

6t ≥ 30

Divide both sides by 6.

t ≥ 5

Answer:

small car: 2

medium car: 2

luxury car: 2

Small van: 2

Large van: 3

Step-by-step explanation:

just multiply the amount per day by numbers increasing from 1 till you get a number that is larger than the week.  I swear whoever made this car rental will not be in business much longer lol.

For 2 days, vehicle can be given to rent before it would be less expensive to rent.

Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.

Given that,

Rent for small car,

For 1 day = $100.

For 1 week = $250

The maximum days in which small car could be given to rent,

= 250 / 100 = 2.5 ≅ 2 days.

Similarly, for medium car = 290 / 110 = 2.7 ≅ 2 days.

For luxury car = 325 / 120 = 2.54  ≅ 2 days.

For small van = 350 / 150 = 2.3  ≅ 2 days.

And for large can = 390 / 170 = 2.28  ≅ 2 days.

Each car can be rented for 2 days before it would be less expensive for the week.
