Line segment ĀB has endpoints of A(-3,7) ans B(3,15). Identify the slope of a line perpendicular to ĀB

Answers

Answer 1

Answer:

m = -3/4

Step-by-step explanation:

Let's look at how much x and y change as we move from A to B:

x increases by 6, from -3 to 3, and y increases by 8, from 7 to 15.  Thus, the slope, m, is rise / run, or (change in y):  m = 8/6 = 4/3.

Now any line perpendicular to AB has a slope which is the negative reciprocal of this 4/3:  m = -3/4

A bag contains 18 balls. There are 6 red balls, 6 yellow balls, and 6 green balls. A ball is drawn at random and returned. Then another ball is drawn at random. Select ALL statements that are true.

A. The expected probability of drawing a green ball first is the same as the expected probability of drawing a green ball second.

B.There are six possible outcomes.

C.The probability of drawing a red ball first is the same as not drawing a red ball second.

D.The expected probability of drawing a red ball and then a yellow ball is 19.

Answers

Answer:

There are 18 balls in the bag:

6 are red

6 are yellow

6 are green.

A ball is drawn at random and then returned.

Then another ball is drawn.

Now, let's analyze each option and let's see if it is true or not.

A) The probability of drawing at random a green ball is equal to the quotient between the number of green balls and the total number of balls.

Then for the first draw, the probability is 6/18

Because the drawn ball is returned, for the second draw we still have 6 green balls and 18 balls in total, then the probability still is 6/18

Statement A is true

B) if we define the notation:

YR

as:

Yellow in the first draw, red in the second draw.

The possible outcomes are:

YR

YG

YY

RR

RG

RY

GR

GG

GY

So we have a total of 9 outcomes, we also can calculate this in the following way:

For the first event (first draw) we have 3 possible outcomes (Y, G, and R)

For the second event (second draw) we have again 3 possible outcomes.

The total number of outcomes is the product between the possible outcomes for each event, this is:

3*3 = 9

Then statement B is false.

C) The probability of drawing a red ball first is:

p = 6/18

The probability of NOT drawing a red ball second, is equal to the probability of drawing a yellow or green ball second (we have 12 balls that are green or yellow, and 18 total balls) then this probability is:

q = 12/18

The probabilities are different, then we can conclude that statement C is false.

fD) The expected probabilty of drawing a red ball and then a yellow ball is the product of the individual probabilities, this is:

prob of drawing a red ball first = 6/18

prob of drawing a yellow ball second = 6/18

Joint probability:

P = (6/18)*(6/18) = (1/3)*(1/3) = 1/9

So statement D is true.  (it says 19, i suppose that there is a mistake in this sentence and it actually should say 1/9)

Write an equation of the perpendicular bisector of the segment with endpoints M(1,5) and N(7,−1).​

Answers

Answer:

y = x - 2

Step-by-step explanation:

Going from M to N, the run (increase in x) is 6, from 1 to 7.  The rise (which is actually a decrease here) is -6, from 5 to -1.  Thus, the slope of the line segment MN is m = rise / run = -6/6, or -1.

The slope of the perpendicular bisector is the negative reciprocal of this m = -1, and is +1.

This bisector passes through the midpoint of segment MN.  The x-coordinate of this midpoint is (1 + 7)/2, or 4, and the y-coordinate is (5 - 1)/2, or 2:  (4, 2).

Knowing both a point on this bisector (4, 2) and the slope of the bisector (+1), we can modify the point-slope form of the equation of a straight line, y - k = m(x - h), to obtain y -2 = 1(x - 4), or y = 2 + x - 4, or y = x - 2

Michael has 938cups of glue. He wants to put 11956cups into each smaller container. How many smaller containers can he fill?

Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't well written. Let's reframe it and solve.

Michael has 938cups of glue. He wants to put 11 cups into each smaller container. How many smaller containers can he fill?

To solve this question, we have to divide the total cups of glue that Michael has by the number of cups that he wants to put in each container. This will then be:

= 938 / 11

= 85 3/11

Therefore, he can fill 85 containers.

To solve the question in case you've different numbers, just follow the steps above and you'll get it.

One number is 6 more than other number. Also, 7 times the smaller number is equal to 6 times the
larger number. Find the two numbers.

Answers

Answer:

The numbers are 36 and 42

Step-by-step explanation:

Represent the two numbers  by m and n, m being the larger number and n the smaller.  Then

m = n + 6.  also, 7n = 6m

Substitute n + 6 for m in the second equation:  7n = 6(n + 6).

Performing the indicated multiplication, we get 7n = 6n + 36, or n = 36.

Then m = n + 6, which here is m = 36 + 6 = 42.

The numbers are 36 and 42.

Hello!

This question is relating powers and simplification.

Let's look at the term in the denominator first, which is [tex]d^0[/tex].

The zero exponent rule states that anything to the 0th power, will be 1.

Meaning that we can simplify this expression to [tex]6c^{-3}[/tex].

Now let's look at the term we have left.

The negative exponent rule states that anything to the negative power can be moved to the other side of the fraction and have its exponent turn into a positive exponent.

Meaning that we can simplify [tex]6c^{-3}[/tex] to [tex]\frac{6}{c^3}[/tex].

Two polygons are congruent if and only if there exists a composition of __ that maps one polygon to the other polygon.

Answers

Answer:

two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.

(instead of translations/rotations we could write transformations, but there are transformations that also change the size of the figure, so I think that writing translations/rotations is more precise)

Step-by-step explanation:

Two figures are congruent if they have the same shape and size.

So for example, if we have one triangle, and we reflect that triangle along some line, those bot images will have the same shape and size (but maybe different orientations) so the triangles are still congruent.

Also, we could translate the image, or simply rotate it along some point, and the resulting image will be congruent to the initial image.

Then two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.

The composition that maps one polygon to the other polygon to make both congruent is called; Similarity transformation.

In transformations in mathematics, it could involve dilation, translation, rotation e.t.c

Now, we are told that there has to be a composition that will map one polygon to another one. This means that the two polygons must have the same shape after transformation.

The only method of transformation that can achieve mapping of one polygon to another is called similarity transformation.

Lines AB and CD are parallel. If 6 measures (3x - 31)°, and 5 measures 148°, what is the value of x? A. x = 21 B. x = 212 C. x = 148 D. x = 11

Answers

Answer:

x = 21

Step-by-step explanation:

If lines AB and CD are parallel, then we can assume that m<5 and m<6 are supplementary that is the sum of both angles is 180degrees

Hence;

3x - 31 + 148 = 180

3x + 117 = 180

Subtract 117 from both sides

3x+117-117 = 180 - 117

3x = 180 - 117

3x = 63

x = 63/3

x = 21

Hence the value of x will be 21 if both angles are supplementary
