On solving the provided question, we can say that the probability that a 2 or 5 is NOT rolled is - 1- 1/3 = 2/3

A branch of mathematics called probability describes the likelihood that an event will occur or that a proposition is true. The probability of an event ranges from 1 to 1, with 1 indicating certainty and numbers in between indicating the difficulty of the event.

to determine the likelihood of rolling a die with a 2 or a 5 on it. The probability formula can be used to do this.

[tex]P(E) = (Number of times event occurs)/(Total number of trials)[/tex]

S = 1, 2, 3, 4, 5, 6 is a sample space of potential results when rolling a dice.

If the likelihood of rolling a die and having a result of 2 or 5 is event E.

Number of occurrences [n(E)] = 2

[n(S)] = 6 trials in all

[tex]P(E) = 2/6 = \frac{1}{3}[/tex]

So, the probability that a 2 or 5 is NOT rolled is - \

The point zero represents option (A) the location of the starting line

Here, -35 represents the starting location of a race car that is 35 yards behind the starting line.

Therefore, the location of the starting line = starting location of a race car that is 35 yards behind the starting line + 35

Substitute the values in the equation

The location of the starting line =  -35 + 35

Add the numbers

= 0

The ending location of a race car = 35

Thar is 35 yards in front of the starting line

Answer:

∠ 2 = 66°

Step-by-step explanation:

∠ 1 and ∠ 2 are same- side interior angles and sum to 180° , then

∠ 2 + 114° = 180° ( subtract 114° from both sides )

Answer:

To simplify this expression, we need to combine like terms. To do that, we need to combine terms that have the same variables raised to the same powers.

First, we will combine the terms in the first set of parentheses:

(4m²n² + 6m²n)

We see that the terms have the same variables, m and n, and the same powers, 2 and 1, respectively. We can combine these terms by adding their coefficients:

(4m²n² + 6m²n) = (4 + 6)m²n = 10m²n

Next, we will combine the terms in the second set of parentheses:

(8m²n^ - 7m²n² - 13m²n)

In this case, we see that the first two terms have the same variables and powers, so we can combine them by adding their coefficients:

(8m²n^ - 7m²n² - 13m²n) = (8 - 7)m²n^ - 13m²n = m²n^ - 13m²n

We can then combine the remaining term with the first term in the expression:

m²n^ - 13m²n + 10m²n = m²n^ + (-13 + 10)m²n = m²n^ - 3m²n

Finally, we will combine the terms in the third set of parentheses:

(14m²n - 2m^n² + 9m²n)

In this case, we see that the first two terms have the same variable and power for the m variable, but the powers of the n variable are different. Since we cannot combine these terms, we will need to leave them as is. We can, however, combine the remaining term with one of the other terms:

(14m²n - 2m^n² + 9m²n) = 14m²n - 2m^n² + (9 + (-14))m²n = 14m²n - 2m^n² - 5m²n

We can then combine this expression with the previous one:

14m²n - 2m^n² - 5m²n + m²n^ - 3m²n = (14 - 1)m²n - 2m^n² - (5 - 3)m²n = 13m²n - 2m^n² - 2m²n

Finally, we have simplified the expression as much as possible:

(4m²n² + 6m²n) - (8m²n^ - 7m²n² - 13m²n) - (14m²n - 2m^n² + 9m²n) = 13m²n - 2m^n² - 2m²n

The combined area of the shaded triangles in figure one is 2ab. We have four congruent right triangles given, with legs a and b. The formula to calculate the area of a right triangle is (leg * leg) / 2. So the area of one of the triangles is ab/2. We have four of these triangles, so ab/2 * 4 = 2ab.

The area of the unshaded square in figure one can be represented as c^2. Since the side of the square is given as c, its area must be c^2 (calculate the area of a square by multiplying its side length by itself).

The combined area of the unshaded squares in figure 2 can be represented by a^2 + b^2. Again, we find the areas of each square by multiplying the side lengths togther: (a * a) + (b * b) = a^2 + b^2.

Finally the areas of the squares in figure one and figure two show that a^2 + b^2 = c^2. This is because the shaded triangles in figure one take up the same area as that of figure two. And since the total figure areas are the same, the unshaded parts of each figure must be equal to each other. Therefore, we have a^2 + b^2 = c^2. This is also known as the Pythagorean Theorem.

Proportionately, the sorting machine will take 100 minutes (1 hour and 40 minutes) to process 720 tons if it takes 50 minutes to process 360 tons.

Proportion is the ratio or numerical relationship that one quantity bears to another.

Proportions are equated to each other to find missing variables.

Proportions are fractional values, usually depicted as fractions, decimals, or percentages.

The total number of oranges to sort = 720 tons

Machine processing speed = 360 tons per 50 minutes

Proportionately, the machine can process 7.2 tons per minute (360/50).

The time to sort 720 tons = 100 minutes (720/360 x 50) or (720/7.2)

The area of the sector and length of the arc are 4.7 unit squared and 3.14 units respectively.

A sector is a portion of a circle which is enclosed between its two radii and the arc adjoining them.

The area of sector of a circle is the amount of space enclosed within the boundary of the sector.

Therefore,

area of the sector = 1 / 2 r²∅

area of the sector = 1 / 2 × 3² × π / 3

area of the sector = 9π / 6

area of the sector = 3 / 2 × 3.14

area of the sector = 4.71 units²

Length of the arc = r∅

where

Therefore,

Length of the arc =  3 × π / 3

Length of the arc = π

Length of the arc = 3.14 units

An average man can lift the weight of $ 150 in quarters

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total weight an average man can lift be = A

Now , the weight of an average quarter = 0.2 ounces

Now , Number of quarters in $ 1 = 4 quarters

Let the total amount be = $ 150

So , the number of quarters in $ 150 is given by the equation

Number of quarters in $ 150 = 150 x 4

Substituting the values in the equation , we get

Number of quarters in $ 150 = 600 quarters

And , the weight of 600 quarters = 600 x weight of an average quarter

Substituting the values in the equation , we get

Number of quarters in $ 150 = 600 quarters

The weight of 600 quarters = 600 x 0.2

The weight of 600 quarters = 120 ounces

Therefore , the value of A is 120 ounces

Hence , an average man can lift the weight of $ 150 in quarters

The expression of the inequality is -0.96 ≤ 0.3x and the solution will be x ≥ -3.2 thus, option (D) is correct.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given,

-0.96 ≤ 0.3x

Divide by 0.3 into both sides of the above equation,

-0.96/0.3 ≤ x

x ≥ -3.2

Answer:

Step-by-step explanation:

You want Marissa's total bill when she bought three cartons of ice cream at $4.59 each and two packages of plastic bowls at $3.00 each, with the plastic being taxed at 5%.

The amount for each item will be the product of the cost per unit and the number of units.

  ice cream total = 3 × $4.59 = $13.77

  plastic total = 2 × $3.00 = $6.00

The tax is applied only to the plastic, so the amount of tax is ...

  5% × $6.00 = $0.30

The total bill is the sum of the item costs and the tax:

What is cost?

A cost is the value of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting. In the case of an acquisition cost, the money spent on the acquisition is considered the cost.

Given:

Andrew buys 8 bottles of cranberry juice at the corner store for a total cost of $5.68.

So, the cost of each bottle is,

$5.68/8 = $0.71
