Trigonometry question

ehidna [41]

Answer:

The scale factors that make figure smaller are the option D. -0.5 and the option E. 0.25

Step-by-step explanation:

we know that

If the absolute value of the scale factor is greater than 1, then the image will be larger than the pre-image.

If the absolute value of the scale factor is less than 1, then the image will be smaller than the pre-image.

If the absolute value of the scale factor is equal to 1, then the image will be the same size than the pre-image.

Additionally, a negative scale factor causes the dilation to rotate 180 degrees

therefore

In this problem

The scale factors that make figure smaller are the option D. -0.5 and the option E 0.25

Find a parametric representation of the solution set of the linear equation. (Enter your answer as a comma-separated list of equ

STALIN [3.7K]

Answer:

x = s, y = t, z = 8 -s -t

Step-by-step explanation:

It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.

You could get more elaborate if you want:

x = 4-s, y = 4-t, z = s+t

Rewrite the following equation in standard form and determine if there is a solution.

Debora [2.8K]

Answer:

| x + 4 | = -1 No solution

Step-by-step explanation:

3 | x + 4 | + 12 = 9

Subtract 12 from both sides: 3 | x + 4 | = -3

Divide both sides by 3: | x + 4 | = -1

Absolute value cannot be negative, so there is no solution.

Predict the products of the double replacement reactions given. Check to see that the equations are

Snowcat [4.5K]

The balanced equation for the given reaction $\mathbf{AgNO_3+NaCl \to AgCl_{(s)} + NaNO_3}$

<h3>What is a double replacement reaction?</h3>

A double replacement is a chemical reaction that takes place in which two reactants swap cations or anions to produce two distinct products.

Whenever the cations representing one of the reactants interact with the anions from another reactant to produce an insoluble ionic compound, a precipitate occurs.

The balanced equation for the given reaction:

$\mathbf{AgNO_3+NaCl \to AgCl_{(s)} + NaNO_3}$

Given the box plot, will the mean or the median provide a better description of the center? box plot with min at 11, Q1 at 22. 5

Slav-nsk [51]

The median, because the data distribution is skewed to the right.

Given that

The box plot with the following parameters:

Minimum value at 11,

First Quartile, Q1 at 22.5,

Median at 34.5,

Third Quartile, Q3 at 36,

Maximum value at 37.5.

According to the question

When a distribution has a longer tail to one of its sides, then it is said to be skewed.

Since the tail is longer to the left, it is said to be left-skewed.

The data distribution is skewed to the left because the median (34.5) is closer to the third quartile (36) than to the first quartile (22.5).

For skewed data, we always prefer the median because it is less affected by the outliers and if the mean is chosen, the value of the mean is biased towards the side that has larger values while the median does not get affected by it. So, we choose the median.

For skewed distributions, the median is the best measure of center.

Hence, the median, because the data distribution is skewed to the right.
