Answer:

The distance between T and S is 10 units.

Step-by-step explanation:

Given the points

\(\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\)

The distance between T and S is:

\(=\sqrt{\left(2-2\right)^2+\left(6-\left(-4\right)\right)^2}\)

\(=\sqrt{\left(2-2\right)^2+\left(6+4\right)^2}\)

\(=\sqrt{0+10^2}\)

\(=\sqrt{10^2}\)

\(=10\)              ∵ \(\mathrm{Apply\:radical\:rule\:}\sqrt[n]{a^n}=a,\:\quad \mathrm{\:assuming\:}a\ge 0\)

Therefore, the distance between T and S is 10 units.

The triangles are similar by SSS congruence of triangles.

What is SSS congruence of triangles?

The two triangles are congruent if the three sides of one triangle are the same as the corresponding three sides (SSS) of the other triangle.

We are given two triangle ABC and PQR.

In order to see whether these are similar or not, we will use the SSS congruence of triangles.

The ratio of sides are:

⇒AB : PQ = 8 : 6

⇒AB : PQ = 4 : 3

Similarly,

⇒BC : QR = 12 : 9

⇒BC : QR = 4 : 3

Similarly,

⇒AC : PR = 12 : 9

⇒AC : PR = 4 : 3

Since, the ratio of all the sides is same so, the triangles are similar.

Hence, the triangles are similar by SSS congruence of triangles.

Complete question is;

Determine whether the random variable is discrete or continuous.

a. The time it takes to fly from City Upper A to City Upper B.

b. The time it takes for a light bulb to burn out.

c. The number of fish caught during a fishing tournament.

d. The number of textbook authors now sitting at a computer.

e. The distance a baseball travels in the air after being hit.

a. Is the time it takes to fly from City Upper A to City Upper B discrete or​ continuous? A. The random variable is discrete. B. The random variable is continuous.

Answer:

a) continuous random variable.

b) continuous random variable

c) discrete random variable

d) discrete random variable

e) continuous random variable

Step-by-step explanation:

A discrete variable is one where the value of the variable is gotten by counting the variables.

Meanwhile, a continuous variable is one where the value of the variable is gotten by measuring the variables.

For options a & b, the time taken is the variable that is measured. Thus, they are both continuous random variable.

Also, for option e, the distance traveled is the measured variable and thus it is also a continuous random variable.

In option c, the number of fishes can be counted. Also, for option d, the number of textbook authors can be counted. Thus, the values of the variables can be gotten by counting. . Therefore, they are both discrete random variable.

The correct step to prove that \(BC^2 = AB^2 + AC^2\) is:

By the cross product property, \(AC^2 = BC \cdot AD\).

To prove that \(BC^2 = AB^2 + AC^2\), we can use the triangle similarity and the Pythagorean theorem. Here's a step-by-step explanation:

Given triangle ABC with right angle at A and segment AD perpendicular to segment BC.

By triangle similarity, triangle ABD is similar to triangle ABC. This is because angle A is common, and angle BDA is a right angle (as AD is perpendicular to BC).

Using the proportionality of similar triangles, we can write the following ratio:

\($\frac{AB}{BC} = \frac{AD}{AB}$\)

Cross-multiplying, we get:

\($AB^2 = BC \cdot AD$\)

Similarly, using triangle similarity, triangle ACD is also similar to triangle ABC. This gives us:

\($\frac{AC}{BC} = \frac{AD}{AC}$\)

Cross-multiplying, we have:

\($AC^2 = BC \cdot AD$\)

Now, we can substitute the derived expressions into the original equation:

\($BC^2 = AB^2 + AC^2$\\$BC^2 = (BC \cdot AD) + (BC \cdot AD)$\\$BC^2 = 2 \cdot BC \cdot AD$\)

It was made possible by cross-product property.

Therefore, the correct step to prove that \(BC^2 = AB^2 + AC^2\) is:

By the cross product property, \(AC^2 = BC \cdot AD\).

Answer:

Step-by-step explanation:

Given that,

To find the standard form of the equation of the parabola with a focus at (0, 9) and a directrix y = -9.

What is a parabola?

A parabola is a cross-section cut out of the cone and represented by an equation

Focus of the prabola = (h , k + F ) =  (0, 9)

Since the directrix, y =  -9

F = -9

k + F = 9

k = 0

Vertex of the parabola = (h,  k  )

                                    =  (0, 0)

Standard equation of the parabola

( y - k ) = 4a (x - h)²

( y - 0 ) = 4a (x - 0)²

y = 4 * 9 x²

y = 36 x²

Thus, the required expression for the parabola with focus at (0, -9) and a directrix y = 9 is y = 36x².

Step-by-step explanation:

y+y = 9-3

2y = 6

y = 3

Answer:

3

Step-by-step explanation:

1. Regroup terms.

y+3=9−y

2. Subtract 33 from both sides.

y=9-y-3y=9−y−3

3. Simplify  9-y-39−y−3  to  6-y6−y.

y=6-yy=6−y

4. Add yy to both sides.

y+y=6y+y=6

5. Simplify  y+yy+y  to  2y2y.

2y=62y=6

6. Divide both sides by 22.

y = 6/2

Answer:

Step-by-step explanation:

To get the y values all you need to do is substitute the x value in the equation y=-2/3x+7.

For example:

y=-2/3(-6)=7

-2/3x6=-4

-4+7=3

(-6,3)

You can double check your work by filling the x and y coordinates in the equation and when solved if it it true you know you were correct.

To get the x value, you need to fill in the y in the equation y=-2/3x+7

for example:

5=-2/3x+7

-2=-2/3x

3=x

(3,5)

y=-2/3x+7

y=-2/3(15)+7

y=-10+7

y=-3

(15,-3)

y=-2/3x+7

15=-2/3x+7

8=-2/3x

Answer:

(a) To find the mean of the data set, sum up all the values and divide by the total number of values.

44 + 44 + 54 + 54 + 65 + 39 + 54 + 44 = 398

Mean = 398 / 8 = 49.75

Rounded to one decimal place, the mean of this data set is 49.8.

(b) To find the median of the data set, i need to arrange the values in ascending order first:

39, 44, 44, 44, 54, 54, 54, 65

The median is the middle value in the sorted data set. In this case, we have 8 values, so the median is the average of the two middle values:

(44 + 54) / 2 = 98 / 2 = 49

Rounded to one decimal place, the median of this data set is 49.0.

(c) To determine the modes of the data set, identify the values that appear most frequently.

In this case, the mode refers to the value(s) that occur(s) with the highest frequency.

From the data set, i see that the value 44 appears three times, while the value 54 also appears three times. Therefore, there are two modes: 44 and 54.

a) Type of research hypothesis is tested in this study is causal RH

b) Type of design is being used in this study is non-experiment

c) Type of design is being used in this study is within-subjects design

d) No, the design used in this study cannot provide an appropriate test of the research hypothesis.

(a) The research hypothesis being tested in this study is a causal hypothesis. The company president believes that the type of music listened to can predict production line output.

(b) The type of design being used in this study is a non-experiment. The researcher is not manipulating the type of music listened to; instead, the plant is naturally exposed to either country or classical music.

(c) The design being used in this study is within-subjects design, as the same group of individuals is exposed to both types of music. It is also a repeated measures design, as the same individuals are measured twice (once under country music and once under classical music).

(d) No, the design used in this study cannot provide an appropriate test of the research hypothesis. Since the researcher is not manipulating the type of music listened to, it is possible that other variables could be affecting the production line output, such as different environmental conditions on each week, or different levels of motivation.

Therefore, it is difficult to determine if any differences in production line output are actually due to the type of music listened to. A true experiment with random assignment of workers to the two music conditions would provide a better test of the research hypothesis.

Answer:

  PJ ⊥ KP

Step-by-step explanation:

The little square corner at point P is the mark that indicates lines are perpendicular.

That is the only on mark indicating perpendicular in this diagram. It shows line KI to be perpendicular to line MJ. Then all of the segments on one of those lines are perpendicular to any of the segments on the other of those two lines.

Just to make sure we don't get in trouble with interpretation, we should probably include point P in any segments we list.

  MJ ⊥ KI

  OJ ⊥ KI

  MP ⊥ KI

  OP ⊥ KI

  PJ ⊥ KI

In any of the above, KI can be replaced by KP or PI and the statement will remain true.

_____

Additional comment

Segment NI, being parallel to OP, is also perpendicular to KI. However, it is not marked as such.

MO is perpendicular to PI, but isn't really marked as such.
