Step-by-step explanation:

The probability that Dawn selects a matching pair of socks is approximately 0.267 or 26.7%.

To calculate the probability that Dawn selects a matching pair of socks, we can use the concept of combinations. In this case, we have 3 white, 2 red, and 1 green sock, totaling 6 socks in the drawer. We are interested in finding the probability of selecting a matching pair, which can be either white or red since there is only one green sock.

First, let's find the total possible combinations of selecting two socks from six. This is represented by the formula C(n, k) = n! / (k!(n-k)!), where n is the total number of items and k is the number of items we want to select. In this case, n = 6 and k = 2.

C(6, 2) = 6! / (2!(6-2)!) = 15 total combinations.

Now, let's find the combinations of selecting matching pairs. There are C(3, 2) = 3 combinations for selecting two white socks and C(2, 1) = 1 combination for selecting two red socks. The green sock does not have a matching pair, so it is not considered.

Therefore, the total matching combinations are 3 (white) + 1 (red) = 4.

Finally, to find the probability, we can divide the matching combinations by the total combinations:

Probability = Matching combinations / Total combinations = 4/15 ≈ 0.267.

The total volume of the ice cream, in cubic inches, is \(\frac{44\pi }{3}\).

What is Volume?

With a radius of 2 and a height of 4, the top cone has a volume of

\(\frac{1}{3} \pi (2)^2X4\).

The frustum is created by subtracting a tiny cone with a radius of 1 and a height of 4 from a large cone with a radius of 2 and a height of 8, giving it a volume of \(\frac{1}{3} \pi (2)^2X8-\frac{1}{3} \pi (1)^2X4\)

By combining, we have,

\(\frac{1}{3} \pi (16+32-4)\\\\E=\frac{44\pi }{3}\).

Step-by-step explanation:

Two scenarios that create right angle are 3 and 4.

In both the situations, Pythagoras theorem get satisfy with the sides which theorem is only applicable when there is right angle in the triangle.

Here's the explanation using 3 as an example :

From the statement we can assume that height of the window as the perpendicular(P) and distance from base(B) of the building to William as base of the triangle and line distance from Tom to William as hypotenuse(H) of the triangle.

Therefore, H = 130, B= 36.4 and P = 124.8

By Pythagoras theorem,

H² = P² + B²;

130² = 124.8² + 36.4²,

16900 = 15575.04 + 1324.96,

16900 = 16900

Hence satisfy the Pythagoras theorem, therefore triangle is right angle.

Similarly for the 4 statement.

The probability that at least one of them is a kindergartner; 0.643.

Calculating or estimating how likely something is to occur is what probability is all about. The likelihood of an event occurring can be expressed using words like "certain," "impossible," or "probable."

Probabilities are always expressed in mathematics as fractions, decimals, or percentages with values ranging from 0 to 1.

Calculation for the probability of the one of them is a kindergarden;

The total number of children is 8.

The total number of kindergarden are 3.

The total number of first graders are 5.

Let 'P' be the probability that at least one of them is kindergarden.

P(at least one kindergartner) = 1 - P(no kindergartner) = 1 - P(all first-graders)

The probability that all are first-graders = (5/8)×(4/7)

                                                                  = 5/14

Therefore, P(at least one kindergartner) = 1 - (5/14)

                                                                   = 9/14

                                                                   = 0.643

Therefore, if two children are ill then, the probability that at least one of them is a kindergartner is 0.643.

The factorization of the polynomial b³-1000 is (b-10)(b²+10b+100).

The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.

The given expression is b³-1000.

Here, b³-1000=b³-10³

Using a³-b³=(a – b)(a² + ab + b²), we get

(b-10)(b²+10b+100)

Therefore, the factorization of the polynomial b³-1000 is (b-10)(b²+10b+100).

The equations 12x = 9x^2 + 4, 2x^2 = 6x - 5, and -x^2 - 10x = 34 all have two complex solutions and no real solutions.

The equation 3x^2-5x=-8 has two complex solutions and no real solutions. Let's solve it step-by-step:
1. Start by rearranging the equation in standard quadratic form: 3x^2 - 5x + 8 = 0.
2. Now, we need to use the quadratic formula to find the solutions. The quadratic formula is given by:
x = (-b ± √(b^2 - 4ac))/(2a),
where a, b, and c are the coefficients of the quadratic equation.
In our case, a = 3, b = -5, and c = 8.
3. Substitute the values into the quadratic formula:
x = (-(-5) ± √((-5)^2 - 4*3*8))/(2*3).
Simplifying further:
x = (5 ± √(25 - 96))/(6).
x = (5 ± √(-71))/(6).
4. Since we have a negative value under the square root, we can conclude that the solutions are complex.
5. To express the solutions in complex form, we can write them as follows:
x = (5 ± i√71)/(6),
where i represents the imaginary unit (√(-1)).
Therefore, the equation 3x^2-5x=-8 has two complex solutions and no real solutions. The solutions are x = (5 + i√71)/(6) and x = (5 - i√71)/(6).
Now let's check the other equations:
1. 12x = 9x^2 + 4:
This equation is a quadratic equation in the form ax^2 + bx + c = 0. By rearranging it, we get 9x^2 - 12x + 4 = 0. Applying the quadratic formula, we find two complex solutions, which are x = (2 + i√2)/3 and x = (2 - i√2)/3.
2. 2x^2 = 6x - 5:
Again, rearranging the equation gives us 2x^2 - 6x + 5 = 0. Applying the quadratic formula, we find two complex solutions, which are x = (3 + i)/2 and x = (3 - i)/2.
3. -x^2 - 10x = 34:
By rearranging the equation, we get -x^2 - 10x - 34 = 0. Applying the quadratic formula, we find two complex solutions, which are x = (-5 + i√79)/(-1) and x = (-5 - i√79)/(-1).

To answer this question we have to use BIDMAS (brackets, indices, division, multiplication, addition and subtraction).

1) This means that we first have to do the brackets! We have to be careful to do the division inside the brackets first.

This leaves us with -15 -1.87 × 32 - 4.7

2) We next have to do the multiplication!

Leaving us with -15 - 59.84 - 4.7

3) Now we can just do the subtraction!

Answer: 7/8

Step-by-step explanation:

You can change all the fractions to have equivalent denominators.

The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.

1 1/4 = 1 2/8 = 10/8.

3/8 = 3/8.

Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.

10/8 - 3/8 = 7/8.

Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.
