Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is 2/5?
line n, with slope -5/2
line m, with slope 5/2
line p, with slope 2/5

Answer:

-18

Step-by-step explanation:

\(\frac{2}{3}n=-12 \\ \\ \frac{3}{2} \cdot \frac{2}{3}n=\frac{3}{2}(-12) \\ \\ n=-18\)

We know that the 'x' coordinate represents the perpendicular distance from y-axis, and the 'y' coordinate represents the perpendicular distance from x-axis.

It can also be visualized that (x,y) is a point obtained by moving x units horizontally, and then y units vertically, with respect to the origin.

In the given graph, it is observed that on the x-axis 1 and -1 are marked at 10 grid lines, so the length that each grid step represents is calculated as,

So we found that each step represents 0.1 units.

33.

Consider the given coordinate (0.5,-0.5).

In order to reach this point, move 5 steps right and then 5 steps down. We see that this is the location of Red Rock Canyon.

Thus, Red Rock Canyon is located at (0.5,-0.5).

34.

Consider the given coordinate (-1/2 , 2/5) i.e. (-0.5 , 0.4)

In order to reach this point, move 5 steps left and then 4 steps up. We see that this is the location of Mystery Mountain.

Thus, Mystery Mountain is located at (-0.5 , 0.4).

35.

Consider the location of Brown Bat Cave.

It is situated at distance 8 steps on the right, and 7 steps down.

So it's location can be represented by the coordinate (0.8,-0.7) .

36.

Given that the origin is the location of the treasure.

The Pirate's cove is 7 steps left and 6 steps down. The shortest distance from this point to the treasure will be equal to the hypotenuse of the right triangle with base 0.7 units and height 0.6 units.

Solve for the hypotenuse (H) using Pythagoras Theorem as follows,

Thus, the treasure is approximately 0.922 units from the Pirate's Cove.

37.

Consider that the reflection about origin is characterized as,

The location of Parrot's lake is (-5,5) while the Red Rock Canyon is located at (5,-5).

Both these points satisfy the condition of reflection.

So they will be the image of each other, while considering the reflection about the origin.

Thus, the required locations are Parrot's lake and Red Rock Canyon .

The total number of red marbles in the vase are 10.

A ratio is described as a comparison between two amounts with the same unit to determine the amount of 1 quantity is contained in the other. Ratios are divided into two sorts.

The first is a part-to-part ratio, and the second is a part-to-whole ratio. The part-to-part ratio expresses the relationship between 2 separate entities or groupings.

Now, according to the question;

Let 'x' be the red marbles in the vase.

Let 'y' be the orange marbles in the vase.

The total number of marbles in the vase are 60

x  + y = 60 (equation 1)

The ratio of red marbles to orange ones is 1:5.

Thus, x/y = 1/5

cross multiplying;

5x = y

or y = 5x

substitute the value of y in equation 1;

x  + y = 60 (equation 1)

x  + 5x = 60

6x = 60

x = 10  (red marbles)

Thus, the number of red marbles in the vase are 10.

The probability that the coin will show tails and the cube will show a three, four, or six is 1/4.

The probability of two independent events occurring, we multiply their individual probabilities.

Let's start by determining the probability of the coin showing tails.

Since it is a fair coin, there are two equally likely outcomes: heads or tails.

The probability of the coin showing tails is 1/2.

Next, we consider the number cube.

It is a standard six-sided die, and we want to find the probability of rolling a three, four, or six.

Out of the six possible outcomes (numbers 1 to 6), three of them satisfy our condition (3, 4, and 6).

The probability of rolling a three, four, or six is 3/6 or 1/2.

Now, we can find the probability of both events occurring by multiplying the probabilities together:

P(Tails and 3, 4, or 6) = P(Tails) × P(3, 4, or 6)

= 1/2 × 1/2

= 1/4

The require value of PQ is

A line on which numbers are marked at intervals, used to illustrate simple numerical operations.

Now, given coordinates of two points on number line are

P = -41

Q = 31

Since, PQ is the distance between to points P and Q on a number line.

So, PQ is the absolute value of the sum of their coordinates P and Q.

⇒PQ = |P| + |Q|

⇒PQ = 41 + 31

⇒PQ = 72

Hence the required value PQ is 72.

Option (C)

Step-by-step explanation:

Option (A)

Rise-run ratio from the smaller triangle = \(\frac{\text{Rise}}{\text{Run}}\)

                                                                 = \(\frac{2}{3}\)

Rise-run ratio from the large triangle = \(\frac{4}{6}\)

                                                             = \(\frac{2}{3}\)

\(\frac{2}{3}=\frac{2}{3}\)

Therefore, the ratios of the rise to run are equivalent in both the triangles.

True.

Option (B)

Slope the line AC will be same as segments AB and BC which lie on the same line AC.

Slope of AC = \(\frac{2}{3}\)

True.

Option (C)

Since, the segments AB and BC are the parts of line AC

Slope of AB = Slope of BC = Slope AC

Therefore, slope of AB and BC can not be the same.

False.

Option (D)

Since, segment AB is a part line AC, slope of both will be same.

True.

Option (C) is not true.

The probability best prediction for the number of times that Ellen will draw a blue marble is 200.

Number of blue marbles: 222

Number of red marbles: 333

Total number of marbles: 555

Probability of drawing a blue marble:

222/555

= 0.4

Number of times drawing a blue marble:

300300300 x 0.4

= 120,120,120

Rounded to nearest whole number:

120,120

Ellen has a bag with 333 red marbles and 222 blue marbles in it. She is going to randomly draw a marble from the bag 300300300 times, putting the marble back in the bag after each draw. The best prediction for the number of times that Ellen will draw a blue marble is 200. This prediction is based on the fact that there are more red marbles than blue marbles in the bag. To calculate this, we first need to determine the probability of drawing a blue marble; there are 222 blue marbles out of 555 total marbles, so the probability is

222/555

= 0.4.

Multiplying this by the total number of draws (300300300) gives us 120,120,120. Rounding this to the nearest whole number gives us our prediction of 200 times.

Answer:

multiplicative inverse of -11/21 is -21/11.

The result of the operation -√(-25) - 8√(-16) is -37i.

To perform the indicated operation, we can simplify each term separately and then combine them:

Starting with the first term, we have:

-√(-25)

The square root of -25 is not a real number, as the square root of a negative number is considered to be an imaginary number. Therefore, we can express it as:

-√(-25) = -√(25) * √(-1) = -5i

Moving on to the second term, we have:

-8√(-16)

Similarly, the square root of -16 is an imaginary number. We can express it as:

-8√(-16) = -8√(16) * √(-1) = -8 * 4i = -32i

Now, we can combine the simplified terms:

-√(-25) - 8√(-16) = -5i - 32i = -37i

Therefore, the result of the operation -√(-25) - 8√(-16) is -37i.

The vector (3,9) as a linear combination of the unit vectors i and j is  3 * i + 9 * j

To write the vector (3, 9) as a linear combination of the unit vectors i and j, we need to find the coefficients that multiply the unit vectors to obtain the components of the given vector.

The unit vectors i and j represent the directions of the x-axis and y-axis, respectively. The vector (3, 9) can be expressed as:

(3, 9) = a * i + b * j

where a and b are the coefficients we need to find.

Since the unit vector i corresponds to the x-axis, the coefficient a represents the component of the vector (3, 9) in the x-direction. Similarly, the coefficient b represents the component of the vector (3, 9) in the y-direction.

To find the coefficients, we can equate the corresponding components:

3 = a

9 = b

Therefore, the vector (3, 9) can be written as:

(3, 9) = 3 * i + 9 * j

In this representation, the coefficient 3 indicates that the vector (3, 9) has a magnitude of 3 in the x-direction (i.e., parallel to the x-axis), and the coefficient 9 indicates that it has a magnitude of 9 in the y-direction (i.e., parallel to the y-axis).

The probability that at least two of the balls have the same number is 27.40%

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

Probability requested is equivalent to:

P(at least 2 have same number) = 1 - P(no 2 have the same number)

P(no 2 have same number) = No. of ways to succeed / No. of possible outcomes

No. of ways to succeed = 90P8

No. of possible outcomes = 90^8

No. of ways to succeed =

nPr = n! / (n-r)!

90P8 = 90! / (90-8)!

90P8 = 90! / (82)!

90P8 = 90*89*88*87*86*85*84*83*82! / [(82)!

90P8 = 90*89*88*87*86*85*84*83

90P8 = 3.13x10^15

P(no 2 have same number) = 3.13x10^15 / 90^8

P(no 2 have same number) = 0.73

P(at least 2 have same number) = 1 - P(no 2 have the same number)

P(at least 2 have same number) = 1 - 0.73

P(at least 2 have same number) = 0.2740 = 27.40%
