The image of the transformation is missing so i have attached it;

Answer:

Option C - The transformation is not isometric because the lengths did not remain the same.

Step-by-step explanation:

Transformation means that it preserves the length of  the original figure which means that it is a distance preserving transformation.

Now, from the image of the question attached, the two figures can be said to be isometric if they are congruent.

Now, for the figure displaying the transformation we can see that the size of the original figure has changed.

We can see that the figure is dilated by a scale factor of 2 as each of the sides of the polygon which is a trapezoid is increased by a factor of 2.

Due to the fact that the lengths of sides of the original figure and transformed figure are are not same, we can say that the lengths are not preserved.

Thus, the transformation is not isometric because the lengths did not remain the same.

Answer:

C : It is not isometric because the side lengths did not remain the same.

The difference between groups and the sample size makes the results of a study statistically significant.

Statistical significance is a measure of the likelihood that the results of a study are not due to chance. In order for a result to be statistically significant, it must meet two criteria:

The difference between groups must be large enough to be unlikely to occur by chance. This is typically assessed using a statistical test such as a t-test or an ANOVA.

The result of the test is expressed as a p-value, which represents the probability of obtaining the observed results if there were no true difference between groups. A p-value of less than 0.05 (or 5%) is generally considered to be statistically significant.

The sample size must be large enough to reduce the possibility of sampling error. A larger sample size generally increases the power of a study, making it more likely to detect a true effect.

A possible amount for the median of the distribution is $22.50.

The histogram of the distribution of the amounts of the orders shows a roughly symmetrical distribution with a single peak, and most of the amounts falling between $15 and $30.

To identify the possible amount for the median of the distribution, we need to find the middle value in the ordered data set. Since the data set has an odd number of observations, the median is simply the middle observation.

There are a total of 91 observations, so the middle observation would be the 46th value when the data set is ordered. Looking at the histogram, we can see that the value corresponding to the 46th observation falls between $20 and $25. Therefore, a possible amount for the median of the distribution is $22.50.

Step-by-step explanation:

If each person has one hat the chances (the probability) of them getting their own hat would be 20%. The chances (the probability) of them getting a hat that belongs to one of the other four students would be 80%. Due to there being 5 hats each person owns 1 hat so there would be a 1 out of 5 chance of them getting their own hat.

Answer:

Step-by-step explanation:

The equation of the straight line passing through (5,-10) and making equal but opposite intercept is y = -4x + 10.

​

To solve the problem, we need to know the equation of a straight line

The equation of a straight line in slope intercept form is given by y = mx + c where

Given that the straight line passes through the point (5, -10) and making equal but opposite intercept, its intercept is at (-5, 10)

We need to find the gradient, m by making m subject of the formula in y.

So, m = (y - c)/x

With

m = (y - c)/x

m = (-10 - 10)/5

m = -20/5

m = -4

Substiting m and c into y, we have

y = mx + c

y = -4x + 10

So, the equation of the straight line passing through (5,-10) and making equal but opposite intercept is y = -4x + 10.

a) The median number of hours per week these Year 12 students spend doing homework is 4 hours.

b) If 10% of Year 12 students spend more than k hours per week doing homework, then the value of k is 5.75 hours.

The median is a central value or a middle value in a distribution. The number of values in a dataset is an important factor that determines the calculation of the median. It is a value that cuts the data set into two equal parts.

The data set consists of 20 Year 12 students. Sort the data in ascending order (or descending order) and find the middle value. Then, use the formula for calculating the median. 

a)The number of hours per week the Year 12 students spend doing homework is given as:

3, 3, 3, 3, 3, 3, 3.5, 3.5, 4, 4, 4, 4, 4.5, 5, 5, 5.5, 6, 7, 8, 8.5

Arrange the data in ascending order:

3, 3, 3, 3, 3, 3, 3.5, 3.5, 4, 4, 4, 4, 4.5, 5, 5, 5.5, 6, 7, 8, 8.5

Now count the data, which gives us 20 numbers. The middle value is the 10th and the 11th numbers, which are both 4.

So the median of the number of hours per week Year 12 students spend doing homework is 4 hours.

b) If 10% of Year 12 students spend more than k hours per week doing homework, then the value of k can be found using the following formula:

100% - 10% = 90%

So, 90% of students study for k hours or less.

So, the value of k can be found using the median. The median value is 4 hours, and 90% of students are studying for k hours or less. Therefore, 10% of students study for more than k hours.

k = 10% more than the value of the 90th percentile value, which is given by: k = 5.5 + ((8-5.5)/10)*1 = 5.5 + 0.25 = 5.75 hours.

Therefore, 10% of Year 12 students spend more than 5.75 hours per week doing homework.

Deductive reasoning is a logical approach where one progress from general ideas to specific conclusions. It is provable by deriving conclusions by reasoning.

The factor theorem states that: if the polynomial p(x) is divisible by x - a if and only if p(a)=0 {where p(a) is the remainder of p(x)/(x - a)}

John used the "general idea" of long division to derive the remainder of the polynomial x² - 25 divided by x - 5 to be zero. Which made him to arrive at the conclusion that (x - 5) is a factor of the polynomial x² - 25.

z_1 and z_2 are complex number;

i) z₁z₂ = 8(cos(7π/12) + isin(7π/12))

ii) z₁/z₂ = 2(cos(π/12) + isin(π/12))

To calculate z₁z₂ and z₁/z₂, we need to perform the complex number operations on z₁ and z₂. Let's break down the calculations step by step:

i) To find z₁z₂, we multiply the magnitudes and add the angles:

z₁z₂ = 4cos(cos(π/4) + isin(π/4)) * 2cos(2π/3) + isin(2π/3))

= 8cos((cos(π/4) + 2π/3) + isin((π/4) + 2π/3))

= 8cos(7π/12) + isin(7π/12)

ii) To find z₁/z₂, we divide the magnitudes and subtract the angles:

z₁/z₂ = (4cos(cos(π/4) + isin(π/4))) / (2cos(2π/3) + isin(2π/3))

= (4cos((cos(π/4) - 2π/3) + isin((π/4) - 2π/3))) / 2

= 2cos(π/12) + isin(π/12)

i) z₁z₂ = 8(cos(7π/12) + isin(7π/12))

ii) z₁/z₂ = 2(cos(π/12) + isin(π/12))

The average rate of change for the interval from x = 7 to x = 8 is 3. To find the average rate of change for the interval from x = 7 to x = 8, we need to calculate the slope of the line passing through the points (7, f(7)) and (8, f(8)), where f(x) is the quadratic function with a vertex at (0, -1).

Since the vertex is at (0, -1), we know that the equation of the quadratic function is in the form f(x) = a(x - 0)^2 - 1, where a is a constant. To find the value of a, we can use one of the other points on the graph. Let's use the point (1, 2), which is given in the problem. Substituting these values into the equation, we get:
2 = a(1 - 0)^2 - 1
3 = a
So the equation of the quadratic function is f(x) = 3x^2 - 1. Now we can calculate the slope of the line passing through (7, f(7)) and (8, f(8)):
slope = (f(8) - f(7))/(8 - 7)
= (3(8)^2 - 1 - (3(7)^2 - 1))/(8 - 7)
= (191 - 188)/(8 - 7)
= 3
Therefore, the average rate of change for the interval from x = 7 to x = 8 is 3. None of the answer choices provided match this result, so we cannot select an answer from the options given.

The probability of spinning two greens on the spinner is 1/16.

To find the probability of spinning two greens on the spinner, we need to determine the probability of spinning a green on the first spin and then the probability of spinning another green on the second spin. Since there are 4 equal sections on the spinner and one of them is green, the probability of spinning a green on the first spin is 1/4.

After the first spin, assuming the spinner is put back to its original state, the probabilities for each section remain the same. Therefore, the probability of spinning a green on the second spin is also 1/4.

To find the probability of both events happening (spinning two greens), we multiply the probabilities together:

P(spinning two greens) = P(green on first spin) * P(green on second spin)

= (1/4) * (1/4)

= 1/16

Therefore, the probability of spinning two greens on the spinner is 1/16.
