How to identify points on a Plane?

A plane is defined by a line and a point outside of it. Meanwhile, a line is defined by two points. Thus, whenever we have 3 non-collinear points, we can define a plane.

Let us check each of the given options;

A) There are exactly two planes that contain points A, B, and F;

If these points are collinear, they can't make a plane and If they are not collinear, they define a plane.

Since we can't make two planes with them, then the statement is false.

B) There is exactly one plane that contains points E, F, and B;

Due to the same reasoning in part A, the statement is true assuming the points are not collinear.

C) The line that can be drawn through points C and G would lie in plane X;

The statement is true because both points C and G lie on plane X, and as such the line that connects them also should lie on the same plane.

D) The line that can be drawn through points E and F would lie in plane Y; Similar to above, this statement is true.

E) The only points that can lie on plane Y are points E and F.

This statement is false because infinite points can lie on a plane.

Circle O has secant lines AB and BD intersects circle O at points C and D. if AD=40 degrees and BC=120 degrees, find

Answers

Answer:

Angle AED: 40
Angle BEC: 105

Explanation:
1) To find Angle AED, you have to do arc BC minus arc AD then divide by 2.
120 - 40 = 80.
80 / 2 = 40

2) To find Angle BEC, you have to do arc BA + CD then divide by 2. But that's only angle CED. You'll have to double the number because BEA is vertical; then minus 360.

62 + 88 = 150
150 / 2 = 75
75 times 2 = 150
360 - 150 = 210
210 / 2 = 105
- You'll divide 210 by 2 because of the vertical angles of AED and BEC.

The series is a convergence series and the sum of the series is -8/3

The type of the series

The series is given as:

[tex]\sum\limits^{\infty}_{n = 1} -4(-\frac 12)^{n-1}[/tex]

The above series has the following properties:

First term; a = -4Common ratio, r = -1/2

Start by calculating the absolute value of the common ratio

Absolute value = |-1/2|

This gives

Absolute value = 1/2

The above value is less than 1.

It means that the series converges.

The sum of the series

This is calculated using:

[tex]S_{\infty} = \frac{a}{1 -r}[/tex]

So, we have:

[tex]S_{\infty} = \frac{-4}{1 + \frac 12}[/tex]

Evaluate the sum

Martha and Emily had to sew dresses with beads. Emily had 20% more beads than Martha. Then Emily gave 25% of her beads to Martha. Now Martha has 80 beads more than Emily. How many beads did each dressmaker had at the start?

Answers

Answer:

Emily has about 73 beads and Martha has about 62

Step-by-step explanation:

E = M · 1.2

M + ( .25 · E ) = m

m = 80

Now work backwards to find the answer.

Note that to find the answer you must get rid of the variable E, so you must use the expression M · 1.2 to represent E.

M + ( .25 · M · 1.2 ) = 80

M + .3M = 80

1.3M = 80

Divide both sides by 1.3

M = 61.5

Round to the nearest one

M = 62

Now use this to find E

E = 62 · 1.2

E = 74.4

Round to nearest one

E = 73

The weights of packs of chewing gum for a certain brand have a mean of 47.1 grams and a standard deviation 2.4 grams. The weight of a randomly selected pack of gum has a z-score of 3.11. Which of the following statements is the best interpretation of the z-score?

The weight of this pack of gum is lighter than the mean weight by 3.11 standard deviations.
The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.
The weight of this pack of gum is lighter than the mean weight by 2.4 standard deviations.
The weight of this pack of gum is heavier than the mean weight by 2.4 standard deviations.

Answers

The weight of this pack of gum is heavier than the mean weight by 3.11 standard deviations.

Why is the above statement appropriate ?

The supplied z-score of 3.11 can be best translated as "This pack of gum weighs 3.11 standard deviations more than the mean weight." A z-score indicates how many standard deviations an observation is from the population mean. When an observation has a positive z-score, it is above the mean; when it has a negative z-score, it is below the mean. The selected pack of gum weighs more than the population's mean weight because the specified z-score is positive. Furthermore, a z-score of 3.11 means that the pack of gum weighs 3.11 standard deviations more than the population's mean weight.

A price is divided into 1:11. If the difference between the shares is £180, what is the total prize

Answers

Answer:

£216

Step-by-step explanation:

The total prize will be the sum of the divisions of the prize. The difference of those divisions is given.

divisions

Let P represent the value of the prize. The 1:11 ratio of the parts tells us there are 1 +11 = 12 total parts, and their ratio is P/12 : 11P/12. The sum of these divisions is the whole prize:

P/12 +11P/12 = 12P/12 = P

difference

The difference of the two divisions of the prize is ...

11P/12 -P/12 = £180

10P = £2160 . . . . . . . . multiply by 12 and simplify

P = £216 . . . . . . . . divide by 10

The total prize is £216.

_____

Additional comment

The divisions of the prize are

£216/12 = £18 and 11×£18 = £198

The sum of those divisions is the total prize: £18 +198 = £216.

The total price (prize)the difference between the shares is £180 is £216.

How to determine the total prize

Let's represent the total price as "P." According to the information given, the price is divided into a ratio of 1:11.

The total number of parts in the ratio is 1 + 11 = 12 (1 part for the first share and 11 parts for the second share).

Let the first share be "x" and the second share be "11x" (since the ratio is 1:11).

Now, the difference between the shares is £180:

11x - x = £180

Simplifying:

10x = £180

Now, divide both sides by 10 to find the value of "x":

x = £180 / 10

x = £18

Now, we can find the total price "P" by adding the shares together:

P = x + 11x

P = £18 + £198

P = £216

So, the total price (prize) is £216.

If LN = 12x + 16, what is the length of Line segment L N in units?

Answers

Answer:

LN = 64 units

Step-by-step explanation:

Given M lies on LN, so LN = LM + MN --------------(1)

LN = 12x + 16

LM = 10x + 8

MN = 5x - 4

Substituting the values in equation 1, we get:

12x + 16 = (10x + 8) + (5x - 4)

12x + 16 = 15x + 4

15x - 12x = 16 -4

3x=12

Therefore x=4

LN= 12(4) + 16 = 64 units

Step-by-step explanation:

the third answer.

5/6 is almost 1, 3/8 is almost 1/2, so their difference is close to 1 - 1/2 = 1/2.

and 19/24 is much bigger than 1/2 (which would be 12/24).
