Which statement is true?

So the shaded region represents 30% of the whole. Each individual square on the grid must represent 1/100 of the whole.

A grid is a network of horizontal and vertical lines that intersect at regular intervals to form a pattern of squares, rectangles, or other shapes. It is commonly used as a tool for visualizing and organizing information, such as in maps, charts, graphs, and other types of diagrams. A grid can be simple or complex, depending on its purpose and the level of detail required. Simple grids may consist of only a few lines, while complex grids may have many lines and sub-divisions. In many cases, grids are labeled with coordinates or numbers to facilitate navigation or data analysis.

Here,

If the grid represents 1 in a grid of 100 squares, then each individual square on the grid must represent 1/100 of the whole.

The shaded region covers 30 squares out of the 100 squares in the grid. So the shaded region represents a fraction of the whole that can be calculated by dividing the number of shaded squares by the total number of squares:

30/100

This fraction can be simplified to:

3/10

Therefore, the shaded region represents three-tenths (3/10) of the whole. Alternatively, we can also express this as a percentage by multiplying the fraction by 100:

(3/10) x 100 = 30%

So the shaded region represents 30% of the whole.

Answer:

Step-by-step explanation:

Solve for the variable. Determine if there is one solution, infinitely many solutions, or no solution.

-6x – 12 = 5(-2x – 3)

Let's start by simplifying the right side of the equation:

5(-2x – 3) = -10x - 15

Substituting this back into the original equation, we get:

-6x - 12 = -10x - 15

Next, we can simplify this equation by adding 10x to both sides:

4x - 12 = -15

Finally, we can add 12 to both sides:

4x = -3

Dividing both sides by 4 gives us:

x = -3/4

Therefore, there is one solution, and x equals -3/4.

Answer:

To find the resultant of two forces, you can use the following formula:

R^2 = F1^2 + F2^2 + 2F1F2cosθ

Where R is the resultant force, F1 and F2 are the magnitudes of the two forces, θ is the angle between the two forces, and cosθ is the cosine of the angle.

Plugging in the given values, we get:

R^2 = (500 kg)^2 + (875 kg)^2 + 2(500 kg)(875 kg)cos(100 deg)

R^2 = 250000 + 765625 + 767321.98

R^2 = 1788946.98

R = sqrt(1788946.98) ≈ 1337.3 kg

So the magnitude of the resultant force is approximately 1337.3 kg.

To find the angle that the resultant force makes with the smaller force, we can use the following formula:

tanθ = (F2sinθ)/(F1 + F2cosθ)

Where θ is the angle between the resultant force and the smaller force.

Plugging in the given values, we get:

tanθ = (875 kg sin(100 deg))/(500 kg + 875 kg cos(100 deg))

tanθ = 0.768

θ = tan^-1(0.768) ≈ 36.2 deg

So the angle that the resultant force makes with the smaller force is approximately 36.2 degrees.

Since there are 12 face cards (4 J, 4 Q, 4K) those represent 12/52.  The nonface cards excluding aces (4 twos through 4 tens) represent 36/52.

The expected value is then:

(12/52)($3)+(36/52)(-$2)= -$36/52 or -$0.69 but rounding to one decimal would be -$0.70

By evaluating the linear function in different values of x, we will get the complete table:

Here we have a table of x and f(x) and we want to complete it, to do so, we only need to evaluate the function in different  values of x and then put that in the correspondent places.

if x = -2

f(-2) = (2/3)*-2 - 4

      = -4/3 - 4 = -4/3 - 12/3 = -16/3

if x = 0

f(0) = (2/3)*0 - 4 = -4

if x = 3

f(3) = (2/3)*3 - 4 = 2 - 4 = -2

Answer:

Starting unpaid balance = $5942.00

On April 1st: Starting unpaid balance = $5942.00

On April 10th: $124.00 purchase is made, so the new balance becomes $5942.00 + $124.00 = $6066.00

On April 22nd: $1000.00 payment is made, so the new balance becomes $6066.00 - $1000.00 = $5066.00

On April 28th: $628.00 purchase is made, so the new balance becomes $5066.00 + $628.00 = $5694.00

Step-by-step explanation:

The line should cross over the x-axis at the point (0.5,). The line should cross over the y-axis at the point (0,2). To show this on the graph, like the question is asking, you can place one point at (0,2) and another point at (1,-2).

Theoretically, there is a probability of 23.1%, or about 0.231, chance that a face card will be drawn at random from a deck of playing cards.

Each of the four suits hearts, diamonds, clubs, and spades in a conventional deck of playing cards, which has 52 cards total, has 13 cards (Ace, 2-10, Jack, Queen, and King). Among these 52 cards, there are 12 face cards (Jacks, Queens, and Kings). So the number of face cards is 12, and the total number of cards is 52.

The probability of selecting a face card can be calculated by dividing the number of face cards by the total number of cards:

[tex]P_{face card}[/tex] = [tex]\frac{number of face cards}{total number of cards}[/tex]

= 12 / 52

= 3 / 13

Therefore , the solution of the given problem of angles comes out to be  the detour via Town P is approximately 3.05 km longer .

The largest and smallest walls of a skew are determined by the point at which the lines that make up its ends meet. At a junction, it's possible that two routes will cross. Another result of two objects interacting is an angle. They most closely resemble dihedral shapes. Two line beams can be arranged in a variety of ways between their extremities to form a two-dimensional curve.

Here,

We can determine the length of the road from B to P using the rule of cosines:

=> BP² = AB² + AP² - 2AB(AP)cos(20°)

=>  BP² = x² + 4² - 2x(4)cos(20°)

We can determine the length of the detour via town P by using the rule of cosines once more:

y² = AP² + BP² - 2(AP)(BP)cos(110°)

y² = 4^2 + BP² - 2(4)(BP)cos(110°)

y² = 16 + BP² + 8BP(0.342)

y² = 16 + x² + 16 - 8x(cos(20°))(0.342) + 8(4)(0.342)(BP)

y²= 32 + x² - 2.75x + 1.368BP

=> BP² = x²+ 4² - 2x(4)cos(20°)

=> BP² = x² + 16 - 8x(cos(20°))

=> BP² = sqrt(x² + 16 - 8x(cos(20°)))

=> y² = 32 + x²- 2.75x + 1.368(sqrt(x^2 + 16 - 8x(cos(20°))))

=>  y - x = √(y²) - x

=>  y - x = √(32 + x² - 2.75x + 1.368(√x² + 16 - 8x(cos(20°))))) - x

With the aid of a computer, we can determine that y - x is roughly 3.05 km.

The outcome that is most likely to occur after rolling the cube 100 times is that an even number would be rolled around 50 times.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

A fair number cube labeled with the numbers 1 - 6 is equally likely to land on any of its faces when rolled.

Therefore, we can use probability to determine which outcome is most likely to occur after rolling the cube 100 times.

"The number 6 would never be rolled." This outcome is highly unlikely, but not impossible.
If the cube is fair, each number has an equal probability of being rolled, so the probability of rolling a 6 on any given roll is 1/6.

The probability of rolling a non-6 on any given roll is 5/6. The probability of not rolling a 6 in 100 rolls is (5/6)¹⁰⁰, which is approximately 0.0001. So, while it is very unlikely that the number 6 would never be rolled, it is not impossible.

"All the numbers rolled would be odd." This outcome is even less likely than the first one.

The odd numbers on the cube are 1, 3, and 5, each with a probability of 1/2.

The probability of rolling an odd number on any given roll is 1/2.

The probability of rolling an odd number on 100 rolls is (1/2)¹⁰⁰, which is an extremely small number, approaching zero.

"An even number would be rolled 50 times." This outcome is more likely than the first two.

The even numbers on the cube are 2, 4, and 6, each with a probability of 1/2.

The probability of rolling an even number on any given roll is 1/2.

If we assume that each roll is independent of the others, the probability of rolling an even number exactly 50 times in 100 rolls can be calculated using the binomial distribution and is approximately 0.0796.

This means that this outcome is not very likely, but still possible.

"The number 7 would be rolled at least once."

This outcome is impossible since the cube is only labeled with the numbers 1 through 6.

Therefore, the number 7 cannot be rolled.

Hence, Based on the above analysis, the outcome that is most likely to occur after rolling the cube 100 times is that an even number would be rolled around 50 times.

The probability that a worker selected at random makes between $350 and $450 is 68%.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

We can start by standardizing the values of $350 and $450 using the formula:

z = (x - mu) / sigma

where x is the value we want to standardize, mu is the mean, and sigma is the standard deviation.

For $350, we have:

z = (350 - 400) / 50 = -1

For $450, we have:

z = (450 - 400) / 50 = 1

Now, we can use the z-score table or calculator to find the probability of a standard normal distribution between -1 and 1, which is approximately 68%.

Therefore, the probability that a worker selected at random makes between $350 and $450 is 68%.

According to your query I am defining you multiply in simple manner.

The term multiply refers to the mathematical operation of repeatedly adding a number to itself a certain number of times. The result of this operation is known as the product. Multiplication is an essential arithmetic operation that is used in various fields, including science, engineering, and economics.

Multiplication is typically represented by the symbol "×" or "*", and the numbers being multiplied are called factors. For example, if we multiply 2 and 3, we get the product 6, which can be written as 2 × 3 or 2 * 3.

Multiplication has several important properties, including the commutative property, which states that the order of the factors does not affect the product. For example, 2 × 3 is equal to 3 × 2.

Another important property of multiplication is the distributive property, which states that the product of a number and the sum of two or more numbers is equal to the sum of the products of the number and each of the individual numbers. For example, 2 × (3 + 4) is equal to (2 × 3) + (2 × 4), which simplifies to 14.

Answer:

The 99% confidence interval for the population proportion is between (0.4526, 0.4960). The interpretation is that we are 99% sure that the true proportion of adults who have started paying bills online in the last year is between these two values.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\dfrac{\pi (1-\pi )}{n} }[/tex]

In which

z is the z-score that has a p-value of [tex]1-\dfrac{\alpha }{2}[/tex].

For this problem, we have that:

In a survey of 2954 ​adults, 1401 say they have started paying bills online in the last year. This means that [tex]n=2954, \ p=\dfrac{1401}{2954} =0.4743[/tex]

99% confidence level

So [tex]\alpha =0.01[/tex], z is the value of Z that has a p-value of [tex]1-\dfrac{0.01}{2} =0.995[/tex], so [tex]Z=2.575[/tex].

The lower limit of this interval is:

[tex]\pi -z\sqrt{\dfrac{\pi (1-\pi)}{n} } =0.4743-2.575\sqrt{\dfrac{0.4743\times0.4408}{2954} } =0.4526[/tex]

The upper limit of this interval is:

[tex]\pi -z\sqrt{\dfrac{\pi (1-\pi)}{n} } =0.4743+2.575\sqrt{\dfrac{0.4743\times0.4408}{2954} } =0.4960[/tex]

The 99% confidence interval for the population proportion is between (0.4526, 0.4960). The interpretation is that we are 99% sure that the true proportion of adults who have started paying bills online in the last year is between these two values.
