Answer:

the answer is \(27\)

Step-by-step explanation:

First, you need to substitute a, b, and c for their sums

So your new problem should look like this... \(2+\left(3-\left(-2\right)\right)^2\)

Then you can begin solving this problem using PEMDAS

So first you're going to start w/ the parenthesis... \(3-\left(-2\right)\) which equals 5

Next, you're going to calculate the exponents, so it should look like this... \(5^{2}\) which equals \(25\)

So now your problem should look like this... \(5+25\) which equals \(27\)

So your answer is \(27\)

(a) Payoff Matrix | Effectiveness for two medicines (in percentage)| Medicine 1 | Medicine 2Medicine 1 | 80, 45 | 0, 100Medicine 2|    0, 0     |   100, 0(b)

For determining the effectiveness of the medicines, we need to have the payoff matrix. Therefore, the payoff matrix giving the effectiveness of the two medicines is given below:The first number in each pair of numbers represents the effectiveness of the first medicine, and the second number in each pair of numbers represents the effectiveness of the second medicine.

Now, to decide which medicine she should use, we need to apply the dominance principle. According to the dominance principle, if one strategy is better than another strategy for every row, then the dominant strategy is the better option to choose.In the payoff matrix, the second medicine is completely effective against the second strain and has no effectiveness against the first strain. In contrast, the first medicine is 80% effective against the first strain and 45% effective against the second strain.

The distance from the center of dilation, Q, to the image of vertex A will be 4 units.

According to the given rule of dilation, D subscript Q, two-thirds, the triangle ABC will be dilated with a scale factor of two-thirds centered at point Q.

Since point Q is the center of dilation and the distance from triangle ABC to point Q is 6 units, the image of vertex A will be 2/3 times the distance from A to Q. Therefore, the distance from A' (image of A) to Q will be (2/3) x 6 = 4 units.

By applying the scale factor to the distances, we can determine that the length of A'B' is (2/3) x  3 = 2 units, the length of B'C' is (2/3) x 7 = 14/3 units, and the length of A'C' is (2/3) x 8 = 16/3 units.

the mean time between failures for the modified components is tested using the p-value method at a significance level of 0.05. The null hypothesis (H0) assumes that the mean time is 520 hours or less, while the alternative hypothesis (H1) suggests that the mean time is greater than 520 hours.

we will use the p-value method of hypothesis testing. The null hypothesis (H0) assumes that the mean time between failures for the modified components is 520 hours or less. The alternative hypothesis (H1) suggests that the mean time between failures is greater than 520 hours.

We start by calculating the sample mean and sample standard deviation of the given data. Using the sample mean and the assumed population mean of 520 hours, we can calculate the test statistic t, which follows a t-distribution with n-1 degrees of freedom (where n is the sample size).

Next, we determine the p-value associated with the obtained test statistic. The p-value represents the probability of observing a test statistic as extreme or more extreme than the calculated value, assuming the null hypothesis is true.

Comparing the p-value to the significance level of 0.05, if the p-value is less than 0.05, we reject the null hypothesis in favor of the alternative hypothesis. This would indicate that there is evidence to support the claim that the mean time between failures for the modified components is greater than 520 hours.

If the Circle Line travels clockwise around a circular track with a radius of 5 kilometers, you are approximately 24.22 kilometers away from your original starting position.

To determine how many kilometers away you are from your original starting position, we can use geometry and the Pythagorean theorem.

First, we need to find the distance you traveled on the Circle Line. Since you traveled 3/4 of the way around the circular track, we can find the distance traveled by using the formula for the circumference of a circle:

C = 2πr = 2π(5 km) ≈ 31.42 km

So, you traveled 3/4 of the circumference, or:

d = (3/4)C = (3/4)(31.42 km) ≈ 23.56 km

Next, we need to find the distance you traveled on the Town Line, which is 7 kilometers south.

Now, we can use the Pythagorean theorem to find the distance between your current location and your original starting position. Since you traveled on a circular track, your original starting position is the center of the circle, and your current location is the endpoint of the two segments you traveled.

The distance between them is the hypotenuse of a right triangle with legs of 5 km (the radius of the circle) and 23.56 km (the distance you traveled on the Circle Line). Using the Pythagorean theorem, we get:

d = √(5^2 + 23.56^2) ≈ 24.22 km

108 triangles Congruent to triangle B would fit inside triangle A.

To determine how many triangles congruent to triangle B would fit inside triangle A, we need to consider the scale factor between the two triangles.

Given that triangle B is similar to triangle A with a scale factor of 1/6, it means that the corresponding sides of triangle B are 1/6 the length of the corresponding sides of triangle A.

Let's calculate the dimensions of triangle B:

Width of triangle B = 1/6 * width of triangle A

Height of triangle B = 1/6 * height of triangle A

Width of triangle B = 1/6 * 7 cm = 7/6 cm ≈ 1.17 cm

Height of triangle B = 1/6 * 20 cm = 20/6 cm ≈ 3.33 cm

Now, to find out how many triangles congruent to B would fit inside triangle A, we need to compare the areas of the two triangles.

Area of triangle A = (1/2) * base * height

Area of triangle B = (1/2) * base * height

Area of triangle A = (1/2) * 42 cm * 20 cm = 420 cm²

Area of triangle B = (1/2) * (7/6 cm) * (20/6 cm) ≈ 1.17 cm * 3.33 cm ≈ 3.89 cm²

To find the number of congruent triangles that can fit inside triangle A, we divide the area of triangle A by the area of triangle B:

Number of triangles congruent to B = Area of triangle A / Area of triangle B

Number of triangles congruent to B = 420 cm² / 3.89 cm² ≈ 108.01

Therefore, approximately 108 triangles congruent to triangle B would fit inside triangle A.

The area and circumference to the nearest tenth include the following:

Area = 490.6 square meters.

Circumference = 78.5 meters.

In Mathematics, the area of a circle can be calculated by using this formula:

Area = πr²

Where:

r represents the radius of a circle.

Note: Radius = diameter/2 = 25/2 = 12.5 meters.

By substituting the radius into the formula for the area of a circle, we have the following;

Area of circle = 3.14 × 12.5²

Area of circle = 490.6 square meters.

In Mathematics, the circumference of a circle can be calculated by using the following mathematical expression:

Circumference of a circle, C = 2πr

Circumference of a circle, C = 2(3.14) × 12.5

Circumference of a circle, C = 78.5 m.

Step-by-step explanation:

1. First we'll find the probability of drawing a blue marble.

P = (No. favourable events)/(Total events)

In this case it's:

P = (No. blue marbles)/(Total Marbles)

Therefore P(Blue) = 4/16 = 0.25

Now we find the probability of drawing a yellow marble:

The total number will be the same because the blue marble will have been put back.

P(Yellow) = 3/16 = 0.1875

Now, since we are calculating the probability of both happening we multiply together the two individual probabilities to get the combined probability of both:

0.25 x 0.1875 = 0.0469 (4.d.p)

2. The probability of drawing a blue marble is still the same so we can keep that: P(Blue) = 0.25

But this time, the marble is not replaced. This means that the total number of marbles has changed when drawing the yellow marble:

P(Yellow) = 3/15 = 0.2

Now we multiply them together again to find the combined probability of both happening:

0.25 x 0.2 = 0.05

There are 2.25 distinct 2-colored necklaces of length 4, up to rotation. Since we cannot have a fractional number of necklaces, we round up to get a final answer of 3.

A necklace is made by stringing together beads in a circular shape. A 2-colored necklace is a necklace where each bead is painted either black or white. How many distinct 2-colored necklaces of length 4 are there? Two colorings are considered identical if they can be obtained from each other by rotation.Let's draw a table to keep track of our count:Each row in the table represents one way to color the necklace, and each column represents a distinct necklace.

For example, the first row represents a necklace where all the beads are black, and each column represents a distinct rotation of that necklace.We start by counting the necklaces where all the beads are the same color. There are 2 of these. We then count the necklaces where there are 2 beads of each color. There are 3 of these.Next, we count the necklaces where there are 3 beads of one color and 1 bead of the other color. There are 2 of these, as we can start with a black or white bead and then rotate.

Finally, we count the necklaces where there are 2 beads of one color and 2 beads of the other color. There are 2 of these, as we can start with a black or white bead and then rotate. Thus, there are a total of 2 + 3 + 2 + 2 = 9 distinct 2-colored necklaces of length 4, up to rotation.  Answer: 9There is a better algebraic way to do this without finding all cases: Using Burnside's lemma. Burnside's lemma states that the number of distinct necklaces (up to rotation) is equal to the average number of necklaces fixed by a rotation of the necklace group. The necklace group is the group of all rotations of the necklace.

The average number of necklaces fixed by a rotation is the sum of the number of necklaces fixed by each rotation, divided by the number of rotations.For a necklace of length 4, there are 4 rotations: no rotation (identity), 1/4 turn, 1/2 turn, and 3/4 turn. Let's count the number of necklaces fixed by each rotation:Identity: All necklaces are fixed by the identity rotation. There are 2^4 = 16 necklaces in total.1/4 turn: A necklace is fixed by a 1/4 turn rotation if and only if all beads are the same color or if they alternate black-white-black-white.

There are 2 necklaces of the first type and 2 necklaces of the second type.1/2 turn: A necklace is fixed by a 1/2 turn rotation if and only if it is made up of two pairs of opposite colored beads. There are 3 such necklaces.3/4 turn: A necklace is fixed by a 3/4 turn rotation if and only if it alternates white-black-white-black or black-white-black-white. There are 2 necklaces of this type.The total number of necklaces fixed by all rotations is 2 + 2 + 3 + 2 = 9, which is the same as our previous count. Dividing by the number of rotations (4), we get 9/4 = 2.25.

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%
