Answer:

I tried solving it and I got an answer of 86c

Hope I helped!! :)

Step-by-step explanation:

If the scale factor is 1, then there is no change -- all measurements remain the same.

So the image and the pre-image would be congruent.

What is the use of a Scalar Factor of Dilation?

The Scalar factor of the dilation determines how larger or smaller the image is when compared to the original object.

we can find a scalar factor of dilation by finding and measuring the center point of dillution and distance from centre point to point on the preimage and also the distance from the center point to the image point.

Expansion occurs when the absolute value of a scalar factor is greater than another one.

comparison occurs when the absolute value of the scale factor is less than another one.

The scale factor can be obtained by dividing the dimension of the new shape by the dimension of the original shape.

The correct choice is A. Using the cofactor expansion across the first row, the determinant of the given matrix is (2)(-13) - (-3)(-5) + (3)(7) = -26 + 15 + 21 = 10.

To compute the determinant using the cofactor expansion across the first row, we multiply each element of the first row by its cofactor and sum them up. The cofactor of an element is determined by taking the determinant of the submatrix obtained by removing the row and column containing that element, and then multiplying it by (-1) raised to the power of the sum of the row and column indices.

For the given matrix:

2  2  1

-3 1  4

3  3 -1

Expanding along the first row, we have:

Det = (2)(cofactor of 2) + (2)(cofactor of 2) + (1)(cofactor of 1)

    = (2)(-13) - (-3)(-5) + (3)(7)

    = -26 + 15 + 21

Extra people required is 50.

Each of the five workers should increase their efficiency to a rate of 15 sandwiches per 10 hour shift.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Question 1 :

Number of associates = 30

Number of direct workers = 30 - 2 = 28

You work 8 hours a day and 5 days a week with two 15 minutes break or 30 minutes break per day.

Direct rate = 150 units per hour

Number of working hours in a week with break = 8 × 5 = 40 hours per week Number of working hours in a week = 7.5 hours per day × 5 days a week

                                                            = 37.5 hours per week

Units that department produce in a 40 hour week = 37.5 × 150 = 5625 units

28 people produce 5625 units in a week

Let x people produce 10,000 + 5625 = 15,625 units in a week

Using proportion,

28 : 5625 = x : 15,625

28 / 5625 = x / 15,625

x = (28 × 15,625) / 5625 = 77.78 ≈ 78

Extra people required = 78 - 28 = 50

Question 2 :

Number of sandwiches made in 10 minutes = 1

Number of sandwiches made in 10 hours = 60

5 workers are there. one worker makes 60/5 = 12 sandwiches

But Deli want number of sandwiches in 10 hours = 75

One worker should make 75/5 = 15 sandwiches instead of 12.

Number of sandwiches made in 8 minutes should be 1.

So the working efficiency on each worker should be increased and produce each one should produce 15 sandwiches in a 10 hour shift.

Hence extra people required in question 1 is 50 and efficiency of each worker in question 2 should be increased to 15 sandwiches in 10 hours shift.

Please find attached the image of the enlargement of the shape X by a scale factor of -1 created using MS Word, which is a drawing equivalent to option B. The correct option is therefore;

B.

An enlargement transformation is one in which the pri-image object size is scaled about a center of enlargement, using a scale factor, with the sign of the scale factor indicating the direction of the enlargement, which for a +ve sign is on the same side, and for a -ve sign is on the other side of the center of enlargement.

An enlargement by a scale factor of -1, can be obtained by producing the image on the alternate side of the center of enlargement, which with a scale factor of -1, is the same size as the size of the image.

Therefore, the dilation by a scale factor of -1, with the center at the origin, produces an image which is equivalent to a reflection of the original object (pre-image), across the y-axis followed by a reflection across the y-axis.

The image of the object following the dilation will therefore be the mirror image of the mirror image of the object reflected across the y-axis, which takes the shape of a vertically flipped, left flipped F, which is option B

Answer:

The change in elevation of the seagull is -16 ft

Step-by-step explanation:

Displacement

The displacement, unlike distance, considers the direction of the lengths occurring in the systems.

To solve the problem, we need to set a zero-level reference. Let's assume the sea level as zero height, any position above this reference as positive, and any position below this reference as negative.

The seagull is flying at a height of 10 ft above the ocean. Thus, its position is positive +10 feet.

The seagull then dives into the water to catch a fish at a depth of 6 feet. This position is negative: -6 ft.

The change in elevation is found by subtracting the final elevation and the initial elevation:

change = -6 ft - 10 ft = -16 ft

The change in elevation of the seagull is -16 ft

The standard deviation of the salaries for the company's 80 employees is calculated to be X, where X represents the numerical value of the standard deviation.

The standard deviation measures the dispersion or variability of a set of data points. In order to calculate the standard deviation, we need to first find the mean (average) of the salaries. Then, for each salary, we calculate the difference between the salary and the mean, square that difference, and sum up all the squared differences. Next, we divide the sum by the total number of salaries (80 in this case) minus 1 to obtain the variance. Finally, the standard deviation is obtained by taking the square root of the variance. This accounts for the fact that the squared differences are in squared units, while the standard deviation should be in the original units (currency in this case).

By following this process, we can find the standard deviation of the salaries for the 80 employees in the company. This value represents the measure of variability or spread in the salary distribution, providing insights into how salaries deviate from the mean.

If we have coins = [1, 2, 5] and amount = 5, then the function should return 4, because there are four combinations of coins that make up an amount of 5: [1, 1, 1, 1, 1], [1, 1, 1, 2], [1, 2, 2], and [5].

This problem can be solved using dynamic programming. Let's define dp[i][j] as the number of combinations of coins using the first i coins to make up an amount j. Then we can use the following recurrence relation:

dp[i][j] = dp[i-1][j] + dp[i][j-coins[i]]

The first term on the right-hand side of the equation corresponds to the case where we don't use the i-th coin, while the second term corresponds to the case where we use the i-th coin at least once. Note that we only need to consider cases where j >= coins[i], because it's impossible to make up an amount less than the value of the i-th coin using that coin.

We can initialize dp[0][0] = 1, because there is exactly one way to make up an amount of zero using no coins. Finally, the answer to the problem is dp[n][amount], where n is the total number of coins.

Here's the Python code:

def change(amount, coins):

   n = len(coins)

   dp = [[0] * (amount+1) for _ in range(n+1)]

   dp[0][0] = 1

   for i in range(1, n+1):

       dp[i][0] = 1

       for j in range(1, amount+1):

           dp[i][j] = dp[i-1][j]

           if j >= coins[i-1]:

               dp[i][j] += dp[i][j-coins[i-1]]

   return dp[n][amount]

For example, if we have coins = [1, 2, 5] and amount = 5, then the function should return 4, because there are four combinations of coins that make up an amount of 5: [1, 1, 1, 1, 1], [1, 1, 1, 2], [1, 2, 2], and [5].

Therefore, the probability that the selected tick is also a carrier of Lyme disease, given that it carries HGE, is approximately 0.999 or 99.9%.

To find the probability that the selected tick is also a carrier of Lyme disease given that it carries HGE, we can use the concept of conditional probability.

Let's define the following events:

A: The tick carries Lyme disease

B: The tick carries HGE

We are given:

P(A) = 0.18 (probability of a tick carrying Lyme disease)

P(B) = 0.07 (probability of a tick carrying HGE)

P(A ∩ B) = 0.07 (probability of a tick carrying both Lyme disease and HGE)

The probability we want to find is P(A|B), the probability of the tick carrying Lyme disease given that it carries HGE.

We can use Bayes' theorem to calculate this:

P(A|B) = (P(B|A) * P(A)) / P(B)

P(B|A) represents the probability of a tick carrying HGE given that it carries Lyme disease. We are not given this information directly, so we need to calculate it.

P(B|A) = P(A ∩ B) / P(A)

= 0.07 / 0.18

= 0.3889

Now we can substitute this value into Bayes' theorem:

P(A|B) = (0.3889 * 0.18) / 0.07

Sums and products of even functions:

An even function is defined as f(x) = f(-x) for all x in the domain.

The sum of two even functions, f(x) + g(x), will also be even because (f+g)(x) = f(x) + g(x) = f(-x) + g(-x) = (f+g)(-x).

The product of two even functions, f(x) * g(x), will also be even because (fg)(x) = f(x) * g(x) = f(-x) * g(-x) = (fg)(-x).

Sums and products of odd functions:

An odd function is defined as f(x) = -f(-x) for all x in the domain.

The sum of two odd functions, f(x) + g(x), will also be odd because (f+g)(x) = f(x) + g(x) = -f(-x) - g(-x) = -(f+g)(-x).

The product of two odd functions, f(x) * g(x), will be even because (fg)(x) = f(x) * g(x) = -f(-x) * -g(-x) = (fg)(-x).

Products of even times odd functions:

When an even function is multiplied by an odd function, the resulting function will be odd because (even * odd)(x) = even(x) * odd(x) = even(-x) * -odd(-x) = -(even * odd)(-x).

Absolute values of odd functions:

The absolute value of an odd function will be an even function because |f(x)| = |f(-x)|.

f(x) + f(-x) and f(x) - f(-x) for arbitrary f(x):

If f(x) is an even function, then f(x) + f(-x) will also be an even function because (even + even)(x) = even(x) + even(-x) = even(x) + even(x) = 2 * even(x).

If f(x) is an odd function, then f(x) + f(-x) will be an even function because (odd + odd)(x) = odd(x) + odd(-x) = odd(x) - odd(x) = 0.

If f(x) is an even function, then f(x) - f(-x) will be an even function because (even - even)(x) = even(x) - even(-x) = even(x) - even(x) = 0.

If f(x) is an odd function, then f(x) - f(-x) will also be an odd function because (odd - odd)(x) = odd(x) - odd(-x) = odd(x) + odd(x) = 2 * odd(x).
