3\sqrt(5)-2\sqrt(20)

Answer:

Answer: The mean increases by 3

Step-by-step explanation:

The original data set is 

{50, 76, 78, 79, 79, 80, 81, 82, 82, 83}

The outlier is 50 because it is not near the group of values from 76 to 83 which is where the main cluster is.

The original mean is M = (50+76+78+79+79+80+81+82+82+83)/10 = 77

If we take out the outlier 50, the new mean is N = (76+78+79+79+80+81+82+82+83)/9 = 80

So in summary so far

old mean = M = 77

new mean = N = 80

The difference in values is N-M = 80-77 = 3

So that's why the mean increases by 3

Answer:

The mean increases by 3 would be the correct answer

Final answer:

The probability of pulling a red marble, then pulling a blue marble without replacement is approximately 0.114.

Explanation:

To calculate the probability of pulling a red marble, then pulling a blue marble without replacement, we need to determine the number of favorable outcomes and the total number of possible outcomes.

The number of red marbles is 5, and the number of blue marbles is 4. When the first marble is pulled, there are a total of 12 marbles. So, the probability of pulling a red marble on the first draw is 5/12.

After pulling out a red marble, the number of blue marbles becomes 3. So, the probability of pulling a blue marble on the second draw is 3/11.

To calculate the overall probability, we multiply the probabilities of each event:

P(Red and then Blue) = P(Red) × P(Blue | Red) = 5/12 × 3/11 ≈ 0.114

Final answer:

The probability of drawing a yellow marble and then a green marble without replacement is 0.1.

Explanation:

The probability of drawing a yellow marble and then a green marble without replacement is calculated as follows:

Calculate the probability of drawing a yellow marble first: 2/9 (2 yellow marbles out of a total of 9 marbles).

Now, after drawing a yellow marble, there are 8 marbles left. Calculate the probability of drawing a green marble next: 4/8 (4 green marbles out of the remaining 8).

Multiply the two probabilities: (2/9) * (4/8) = 1/9 = 0.1111 (rounded to the nearest tenth).

Answer:

18 ferrets

Step-by-step explanation:

From the statement you can write the following:

c+r+f= 108

c=cats

r= rabbits

f= ferrets

Then, you have that one third of the animals are cats:

c= 108*(1/3)= 36

Next, three fourths of the remaining animals are rabbits:

r= (108-36)*(3/4)= 72*(3/4)= 54

Now, as you have determine the amount of cats and rabbits, you can isolate f and find the amount of ferrets:

f=108-c-r

f=108-36-54

f= 18

According to this, the answer is that there are 18 ferrets.

Known :

Sa = 1017.36 yd²

Asked :

r = ...?

Answer :

Sa = 4πr²

1017.36 = 4 × 3.14 × r²

1017.36 = 12.56 r²

r² = 1017.36 ÷ 12.56

r² = 81

r = √81

r = 9 yd

So, the radius is 9 yd (D)

Hope it helpful and useful :)

Answer:

9 yd

Step-by-step explanation:

SA = 4 pi r²

1017.36 = 4 × 22/7 × r²

r² = 1017.36 × 7/88

r = 9 yd

Angle DXC and BXC are complementary angle.

Step-by-step explanation:

∠DXC complements with ∠BXC

Complementary angle means the sum of 2 angles that have a vein or form a right angle, which is 90°.

If we add ∠DXC with ∠BXC, it will form a right angle, 90°.

Hope it helpful and useful :)

We want to find the complementary angle to DXC.

We will see that the complementary angle is CXB

Let's start by defining what complementary angles are.

Two angles a and b are complementary if:

a + b = 90°.

This means that we must find another angle such that when we add it to DXC we get a right angle.

Let's look at the diagram.

We can see that we have the line AD, and there is a segment XB, such that the angle AXB is a right angle.

Then the angle DXB is also a right angle.

Now, you can see that the angle DXB is equivalent to DXC + CXB

Then we can see that the complementary angle to DXC is CXB.

The volume of the cylinder is approximately 21727.938in^3.

The volume (V) of a cylinder is calculated using the formula:

V=πr^2 h

where:

π (pi) is a mathematical constant approximately equal to 3.14159,

r is the radius of the cylinder,

h is the height of the cylinder.

Given that the radius (r) is 16 inches and the height (h) is 27 inches, you can substitute these values into the formula:

V=π×(16in)^2 ×27in

Now, let's calculate the volume. Remember to use the value π as approximately 3.14159:

V≈3.14159×256×27

V≈3.14159×6912

V≈21727.938in^3

So, the volume of the cylinder is approximately 21727.938in^3.

The value of x from the given equation is 7.

The given equation is 6(n-3)-2n=10.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, 6(n-3)-2n=10

6n-18-2n=10

4n-18=10

Transpose -18 to other side of the equation, we get

4n =10+18

To find the volume of a triangular prism, multiply the base area by the height. The formula for the volume of a prism is V = base area x height. In this case, the base is a triangle, so calculate the area using the formula for the area of a triangle. Substitute the values and multiply the base area by the height to find the volume.

To find the volume of a triangular prism, we need to multiply the base area by the height. The formula for the volume of a prism is:

V = base area x height

In this case, the base of the prism is a triangle, so we calculate the area using the formula for the area of a triangle:

area = (base x height) / 2

Substituting the given measurements, we have:

base = 3 cm, height = 4 cm, height of prism = 11 cm

First, find the area of the triangle: area = (3 cm x 4 cm) / 2 = 6 cm².

Then, multiply the base area by the height of the prism: volume = 6 cm² x 11 cm = 66 cm³.

Final answer:

The area of Kara's bedroom floor is 93 1/3 square feet, which is calculated by converting the given dimensions into improper fractions, multiplying them, and then simplifying.

Explanation:

The area of Kara's bedroom floor is calculated by multiplying the room's length by its width. The dimensions of the room are given as 8 3/4 feet by 10 2/3 feet. We first convert these mixed numbers into improper fractions: 8 3/4 becomes 35/4 and 10 2/3 becomes 32/3. To find the area, we multiply these two fractions together:

Area = (35/4) × (32/3) feet2

Now, we find the product of the two fractions:

Area = (35 × 32) / (4 × 3) square feet

Area = 1120 / 12 square feet

Area = 93 1/3 square feet

Therefore, the area of the bedroom floor is 93 1/3 square feet. When purchasing carpet, Kara would need to round up to ensure she has enough carpet to cover the entire floor, which is typically sold by the whole square foot.

Answer:

All real numbers greater than -3

Step-by-step explanation:

The domain of a log is the baseline is greater than 0.

Set x + 3 greater than zero and solve

x + 3 > 0

x > -3

The domain of the function y = log4(x + 3) is all real numbers greater than -3, as the argument of the logarithm must be positive.

The domain of the function y = log4(x + 3) is determined by the values of x for which the logarithmic expression is defined. Since the logarithm of a number is only defined for positive arguments, we need x + 3 to be greater than zero. Therefore, the domain is all real numbers greater than -3.

What this means is x must be any number such that when you add 3 to it, the result is a positive number. A simple inequality expresses this: x + 3 > 0, which simplifies to x > -3. Hence, the correct domain is all real numbers greater than -3.

The polynomial in standard form is –x⁴ + 6x³ + 7x² – 4x – 4, with terms ordered from the highest degree to the lowest degree.

Explanation:

To write the polynomial 7x²-4+6x³-4x-x⁴ in standard form, we need to arrange the terms in descending order of their exponents. The standard form for a polynomial is to start with the highest degree term and go down to the constant term.

So, the polynomial in standard form will be:

-x⁴ + 6x³ + 7x² - 4x - 4.

This polynomial is now in the proper order and ready to be used for further algebraic operations such as factoring or solving for specific values of x.
