The mug has a capacity of 2 1/4 cups of water, as per the given conditions.

Given that,
A mug is 1/3 full. The mug contains 3/4 of a cup of water. Find the capacity of the mug.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
As
1 / 3 of mug = 3 / 4 cups
1 of mug = 3/4 / [1/3]
1 of mug = 3×3 / 4
1 of mug = 9 / 4 cups or 2 1 / 4 cups

Thus, the mug has a capacity of 2 1/4 cups of water, as per the given conditions.

Probability is a mathematical discipline that concerns with numerical figures of how probable an occurrence is to occur or how probably a statement is to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Mean – 385 per ticket

Standard Deviation - 110

Now,

P (Z > x ) = 0.03

Value of z to the cumulative probability of 0.03 from the normal distribution table is 1.88

P(x - u / (standard deviation) > x - 385/110) = 0.03

That is, (x - 385/110) = 1.88

Therefore, x = 1.88 ×( 110+385)

= 591.91 or $592

The equivalent value of the [x] that satisfy the given statement is 18.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis of the given problem.

Given is the statement -

the quotient of a number and three increased by 10 is 16

The given mathematical statement is -

the quotient of a number and three increased by 10 is 16

Assume the number to be [x]. Then, we can write -

(x/3) + 10 = 16

x/3 = 16 - 10

x/3 = 6

x = 6 x 3

x = 18

Correct representations of the inequality -3(2x - 5) 5 are - 6x + 15 10 - 5x (2 – x)

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. [1]

The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:

The symbol a b indicates that an is smaller than b.

When a > b is used, it indicates that an is bigger than b.

A is not equivalent to b in any scenario. Since an is strictly less than or strictly greater than b, these relationships are known as stringent inequalities[1]. Equivalence is not considered.

There are two form of inequality relations that are not strict, in contrast to strict inequalities:

The indication of an or b denotes that.

According to our question-

The fourth response is shown by an open circle at 5, and a bold line that begins at 5 and points to the right (attached figure)

Detailed explanation

The difference is 5 (-3(2x - 5)). (2 - x)

First, make each side simpler.

∵ -3(2x - 5) = -3(2x) + -3(-5) (-5)

Recall that (+)=(-)

∴ -3(2x - 5) = - 6x + 15

∵ 5(2 - x) = 5(2) + 5(-x) (-x)

Recall that (+)(-) = (-)

∴ 5(2 - x) = 10 - 5x

∴ - 6x + 15 < 10 - 5x

Take 15 away from both sides.

∴ - 6x < -5 - 5x

5 times on both sides

∴ - x < - 5

Because the coefficient of x is negate, you must change the inequality's sign when you divide both sides by it.

The x coefficient is -1.

∴ Add -1 to both sides.

∴ x > 5

The appropriate answers are:

- 6x + 15 < 10 - 5x

The length of the side c is equal to 29.54 approximately to 2 decimal place, using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

For the triangle ABC, by sine rule;

a/sinA = b/sinB = c/sinC

We first derive the angle C as follows:

46° + 73° + C = 180° {sum of interior angles of a triangle}

C = 180° - 119

C = 61°

Thus by sine rule;

c/sin61° = 32.3/sin73°

c = (32.3 × sin61°)/sin73° {cross multiplication}

c = 29.5410

Therefore, by proper application of the sine rule we have the length of the side c to be equal 29.54 approximately to 2 decimal place.

The probability that the card is a king and a black card is 1/26.

There are 4 kings in a deck of 52 playing cards, and half of the cards are black, so there is a 1/13 probability that a randomly drawn card is a king, and a 1/2 probability that it is black.

To find the probability that a card is both a king and black, you can use the formula for the probability of the intersection of two events: P(A and B) = P(A) * P(B | A), where P(A) is the probability of event A occurring, and P(B | A) is the probability of event B occurring given that event A has already occurred.

Using this formula, the probability of drawing a king and a black card is:

P(King and Black) = P(King) * P(Black | King)

= (1/13) * (1/2)

= 1/26

So the probability of drawing a king and a black card is 1/26, or about 3.8%.

It will take 6 months for Omari to finish paying off the monthly payment for the computer.

What is the monthly payment?

The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.

Given, the total price of the computer = $1,099

down payment = 20% of $1,099 = $219.8

The remaining amount = $1,099 - $219.8 = $879.2

monthly payments for the computer = $144

Then, the total months to pay = 879.2/144 = 6 months

Answer:

The equation of the sunflower's height is h = 18+2.5w

Since the number 18 remains constant regardless of the change in number of weeks, we know that at the start h (w=0) = 18 + 2.5 x 0.

This means that, when Jin planted the sunflower, the sunflower's height was already 18 inches.

For such a reason, we can conclude that the number 18 could represent the sunflower's height at the start (original height).

The equation which models the distance of the turtle from the pond is q = 26.2 + 3.5p. Option D. is the answer

Given that:

A turtle is 26.2 meters from a pond when it starts crawling toward the pond

The turtle crawls straight toward the pond at a constant rate of 3.5 meters per minute

q represents the turtle's distance, in meters, from the pond and p represents the number of minutes since it started crawling toward the pond

The linear equation is of the form y = mx + c

where m is the rate of change and c is the starting point or y-intercept

m = 3.5 meters per minute, c = 26.2 meters

y = q ( turtle's distance) and x = p (number of minutes)

You should spend 30 minutes on machine 1 and 10 minutes on machine 2.

Given,

In the question:

You have 40 minute to exercise at the gym, and you want to burn a total of 300 hundred calorie using both machine.

Now, According to the question;

300 calories in 40 minutes can be set up as a ratio to find out how many calories per hour or calories per minute you are trying for:

300 calories /40 minutes = x calories/60 minutes for calories per hour (you are aiming for 450 calories burned per hour)

300 calories / 40 minutes = 7.5 calories per minute if you want to look at it that way instead.

One version of this problem that I found online completes the setup this way:

This allows us to set up a system of equations. The first equation will be for calories burned:

8x + 6y = 300

x is minutes on the 8 calorie per minute machine; y is minutes on the 6 calories per minute machine.

A second equation simply shows that the total minutes add up to 40:

x + y = 40

Now you can use substitution, elimination, or linear combinations to solve the system. I'll use substitution to rewrite the second equation:

x = 40 - y....(1)

Now substituting into the first equation:

8(40 - y) + 6y = 300

320 - 8y + 6y = 300

2y = 20

y = 10

Put the value of y in eq.(1)

Then, x gives the 30

Hence, You should spend 30 minutes on machine 1 and 10 minutes on machine 2.

The graph demonstrates that regardless of its value, y is always positive. From the question figure, the following conclusions can be made.

Whenever x is 0, y also equals 0.

If x is 1, then y is 2.

when x is two, y is four.

Y is two when x is -1.

If x is -2, then y is 4.

It implies that the modulus function (|x|) is a function of f(x).

Here is a definition of the modulus function:

g(x)

g(x) = |x| = {x,i∫x≥0

               {-x,i∫x<0

As we can see, it is twice as large as |x|, therefore the graph in the question figure
