The quotient of −273−21 is

Answer:

Mean: 4

Median: 3

Mode: 1

Step-by-step explanation: For the mean, you have to add all the numbers and divide it by the amount of numbers there are to find the average (mean). For the median, you have to order the numbers from least to greatest and since there are 9 numbers and 9 is an odd number, you have to see which number is in the middle, 3 was in the middle for this problem. The mode is which number repeats the most, which was 1.  

Answer:

Mean = 4, Median = 3, Mode = 1

Step-by-step explanation:

The mean is also the average. To find it you add all the numbers up and divide that by the # of numbers given.

[tex]\frac{3+5+1+5+1+1+2+3+1+5}{7} =\frac{28}{7}=4[/tex]

Median is the middle number when all the numbers are written out numerically including the doubles

1 1 1 2 3 3 5 5 15

Mode is the number that appears the most

in this case it is 1

Answer:

Option B

Increases

Step-by-step explanation:

to solve this problem, let us plug in figures to replace the variables in the equation.

Let y be equals to the rational exponent which represents the cube root of x^m,

The equation is given as y =[tex]\sqrt[3]{x^{m}}[/tex]

let x= 3

and m =, 3, 4, and  5

when m = 3, we have [tex]y =\sqrt[3]{3^{3}} =3[/tex]

when m = 4, we have [tex]y =\sqrt[3]{3^{4}} =4.33[/tex]

when m = 5, we have [tex]y =\sqrt[3]{3^{5}} =6.24[/tex]

As we can see, the values of y are increasing. Hence,  we can say that the value of the rational exponent increases as y increases

Final answer:

As the positive integer m increases in the rational exponent expression for the cube root of [tex]x^m[/tex], the rational exponent itself increases. This is because the base x is being raised to a higher power, exemplified by [tex]x^{2/3[/tex] compared to [tex]x^{3/3[/tex], showing an increase in expression value.

Explanation:

If a rational exponent represents the cube root of [tex]x^m[/tex], where m is a positive integer, the form used to represent this is [tex]x^{m/3[/tex]. As m increases, the value of the expression increases because the base (x) is being raised to a higher power. Therefore, the correct answer to how the rational exponent changes as m increases is it increases.

For example, consider x to equal 8, and compare [tex]x^{2/3[/tex] (the cube root of 8 squared) to [tex]x^{3/3[/tex] (the cube root of 8 cubed).

As m increases from 2 to 3, the exponent changes from 2/3 to 3/3 (or 1), and thus the result of the expression goes from 4 to 8, illustrating that the expression's value increases with m.

Answer:

True

Step-by-step explanation:

Final answer:

The statement is True: the locus of points concept is used in geometry to define shapes based on the equality of distances, such as an equidistant curve from a line, or a circle at a fixed distance from a point.

Explanation:

The statement "The locus of points idea allows you to define geometric objects just by determining whether or not two distances are equal" is True. The locus of points is a concept in geometry that represents a set of points that satisfy certain conditions. For instance, the locus of points at a given distance from a straight line is known as an equidistant curve, and when this distance is from a point, it forms a circle. Euclidean geometry often assumes that distances are consistent and measurable, idealizing the real world where we use rules and compasses to define distances and constructs. Concepts like parallelism and measurement systems, as found in axioms, help to build an understanding of geometric relations on lines. Moreover, the validity of geometric propositions can be questioned in real-world applications as geometry serves as an abstraction of physical space.

By using the provided scale factor of 2, we multiply the side length of the first square by 2 to find that the length of JP is 8 inches.

To find the length of JP, we must consider the information given about the dimensions of the larger square. Since the problem states that the dimensions of the larger square are twice that of the first square, we know there is a scale factor of 2 involved in the sizing of the squares. Thus, if the side length of the first square is 4 inches, the side length of the larger square would be 4 inches × 2 = 8 inches.

Answer:

5/18, 0.278, 27.8%

Step-by-step explanation:

In this problem, we basically want to find the probability that Marcus will have a total sum of the 2 dices less than Lucia.

In her throw, Lucia gets a 4 and a 1, so she gets a total sum of 5.

Therefore, we want to find the probability that Marcus will get 5 or less.

The possible combinations that can be obtained when throwing 2 dices are 36 (6 x 6).

Of all these 36 combinations, those that gives a sum of 5 or less are:

1 +1 = 2

1 + 2 = 3

2 + 1 = 3

1 +3 = 4

3 + 1 = 4

1 + 4 = 5

4 + 1 = 5

2 + 2 = 4

2 + 3 = 5

3 + 2 = 5

So, a total of 10 combinations.

Since the probability of an event is:

[tex]p(A)=\frac{s}{n}[/tex]

where

s is the number of successfull outcomes

n is the number of total possible outcomes

Here we have

s = 10

n = 36

Therefore the probability here is

[tex]p=\frac{10}{36}=\frac{5}{18}=0.278 = 27.8\%[/tex]

Hope i could help! :D

Step-by-step explanation:

By the 1993 season, the Miami Dolphins had appeared on Monday Night Football 46 times.

To solve this question, we are given that the San Francisco 49ers had appeared on Monday Night Football 35 times by the 1993 season. We are also informed that the Miami Dolphins had made 11 more appearances than the 49ers. Therefore, to find the total number of times that the Miami Dolphins had appeared, we simply need to add 11 to the 49ers' appearances.

So, 35 (49ers' appearances) + 11 (additional Dolphins' appearances) = 46.

This means that by the 1993 season, the Miami Dolphins had appeared on Monday Night Football a total of 46 times.

Step-by-step explanation:

The average rate of change in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [4, 7 ], thus

f(b) = f(7) = 7² - 4(7) - 1 = 49 - 28 - 1 = 20

f(a) = f(- 4) = (- 4)² - 4(- 4) - 1 = 16 + 16 - 1 = 31

average rate of change = [tex]\frac{20-31}{7+4}[/tex] = [tex]\frac{-11}{11}[/tex] = - 1

The value of [tex]f^{-1}[/tex](-2) is -4 , f(-4) is -2 and f[ [tex]f^{-1}[/tex](-2)] is also -2.

The inverse of a function is basically a reverse function or undo of the function.

For example y = f(x) then inverse will be x = f(y).

It means in the inverse function we need to interchange x and y.

Another example y = 3x² ⇒ x = √(y/3) will be the inverse.

Given the function,

f(x) = 1/2x and  [tex]f^{-1}[/tex](x)= 2x

Now,

[tex]f^{-1}[/tex](-2) = 2(-2) = -4

f(-4) = 1/2 (-4) = -2

Now,

Operation of f is that it will come x variable down,

So,

f[ [tex]f^{-1}[/tex](-2)] = f(-4)

f(-4) = -2

Hence "The value of [tex]f^{-1}[/tex](-2) is -4 , f(-4) is -2 and f[ [tex]f^{-1}[/tex](-2)] is also -2".

Answer:

The population be after 15 years is 171376.

Step-by-step explanation:

Given : A population of 110,000 grows 3% per years 15 years.

To find : How much will the population be after 15 years?

Solution :

Exponential growth population model is given by,

[tex]P(t)=P_o(1+r)^t[/tex]

Where,

P(t) is the population at time (t)

[tex]P_o=110,000[/tex] is the initial value of the population

r=3%=0.03 is the annual rate of growth

t=15 is the time in years.

Substitute the value,

[tex]P(t)=110000(1+0.03)^{15}[/tex]

[tex]P(t)=110000(1.03)^{15}[/tex]

[tex]P(t)=110000\times 1.5579[/tex]

[tex]P(t)=171376.41[/tex]

Therefore, the population be after 15 years is 171376.

Final answer:

The future population after 15 years of 3% annual growth starting with a population of 110,000 is calculated using the exponential growth formula, resulting in approximately 171,380 people.

Explanation:

To calculate the future population given a current population, growth rate, and number of years, you can use the formula for exponential growth:

P(t) = P0 ×[tex](1 + r)^{t}[/tex]

Where:

P(t) is the population after t years.

P0 is the initial population.

r is the annual growth rate (expressed as a decimal).

t is the time in years.

In this case, the initial population (P0) is 110,000, the growth rate (r) is 3% or 0.03, and the time (t) is 15 years.

Applying these values to the formula:

P(15) = 110,000 × (1 + 0.03)¹⁵

Now we compute the amount (rounded to the nearest whole number):

P(15) = 110,000 × 1.03¹⁵

P(15) ≈ 110,000 × 1.558

P(15) ≈ 171,380

Therefore, the population after 15 years will be approximately 171,380 people.

The probability that neither marker chosen from the box is red is 72.25%

The probability that neither marker chosen is red can be calculated by finding the probability of not picking a red marker twice. There are a total of 40 markers (8 green, 10 purple, 6 red, and 16 blue). Therefore, the probability of not picking a red marker on the first try is 34/40 or 0.85 (since there are 34 non-red markers).

Because the marker is replaced, the conditions remain the same for the second draw. Hence, the probability of also not picking a red marker in the second draw remains at 0.85.

As these are two independent events, the total probability of neither marker being red is found by multiplying the probabilities of the individual events. Hence, 0.85 * 0.85 = 0.7225. Hence the probability that neither marker is red is 0.7225 or 72.25%.

To find the probability that neither marker is red, calculate the probability of selecting a non-red marker on each draw and multiply the probabilities together.

To find the probability that neither marker is red, we need to calculate the probability of selecting a non-red marker on each draw.  

The total number of markers in the box is 8 (green) + 10 (purple) + 6 (red) + 16 (blue) = 40.

The probability of selecting a non-red marker on the first draw is (8 + 10 + 16)/40 = 34/40 = 17/20.

Since the marker is replaced back in the box, the probability of selecting a non-red marker on the second draw is also 17/20.

The probability that neither marker is red is the product of the individual probabilities: (17/20) * (17/20) = 289/400.
