ANSWER THIS QUESTION PLEASE

Answers

Answer:

Step-by-step explanation:

Red = 8

Green = 6

Blue = 14

Total = 8+6+14 = 28

(a) Proability of drawing a green bead = 6/28 = 3/14

Answer for (a) = (iv)

(b) Probability of drawing beads that are not green = 8+14/28

                                                                                     = 22/28

                                                                                     = 11/14

Answer for (b) = (iii)

(c) Probability of drawing green or blue beads = (6/28) + (14/28)

                                                                             = (3/14) + (1/2)

                                                                             = 5/7

Answer for (c) = (i)

(d) Probability of drawing (not red and not green beads) = 1 - p(red) -p(green)

                                                                                              = 1 - 8/28 - 6/28

                                                                                              = 1 - 2/7 - 3/14

                                                                                              = 1/2

Answer for (d) = (iv)

Answer for (e) = (iv)

Reason = Aditi runs out of yellow beads for today, so there are no yellow beads in the potli for him/her to use.

The figure on the left is reflected using the y-axis to form the image on the right. Use the information in the original figure to find the measure of side A, side B, angle C and angle D.

Answers

So basically the figure is just flipped over so it’s the same thing as the other side just placed in a different spot. So angle b would be 2.2. Angle a would be 3.2. Look at the other angle and do what I did for angle b and a and you would be able to figure it out.

find three consecutive integers for which 3 times the sum of the first and third integers is -342? show step by step

Answers

Answer:

-58, -57, -56

Step-by-step explanation:

if the first integer is x,

the second integer must be x + 1 (because it's consecutive)

and the third must be x + 2

Therefore:

3 times the sum of the first and third integers is -342:

3 * (x + (x+2) ) = -342

Combine like terms in parentheses

3 * (2x + 2) = -342

Distribute the 3 to the 2x and the 2:

6x + 6 = -342

Subtract 6 on both sides

6x = -348

Divide by 6 on both sides

x = -58

x + 1 = -57

x + 2 = -56

-58, -57, -56

Check:

3 * (-58 + -56) = 3 * -114 = -342

I hope this can help you

can 490 milliliters fit into 200 centimeters?? I wanna buy this calculator that’s length is '14 cm x 12.5 cm x 2.8 cm’ and a pencil case that is '20×10 cm' so I wanted to see if my calc will fit in before I purchase

Answers

Answer:

No

Step-by-step explanation:

The calculator isn't water or a fluid, therefore you have to follow the dimesions by the question. Since the Calculator is 14cm by 12.5cm, and the pencil case is 20cm by 10cm, the calculator cannot simply fit inside the pencil case as the calculator's width is longer than the pencil case's width. We do not include the height in this question as the pencil case's height is not included

Which of the following appears to be a scaled copy of the original image? *
YOU CAN CHOOSE MORE THAT ONE

Answers

Answer: Third Choice. B,C, and E

Concept:

A scaled copy is a copy of a figure where every length in the original figure is multiplied by the same number.

Explanation:

Choice A. [tex]\boxed{FALSE}[/tex]

The figure given as choice A seems to be much thinner than the original image. Therefore, the figure did not copy each length in scale.

Choice B. [tex]\boxed{TRUE}[/tex]

The figure given as choice B seems to be the same size as the original image but different position. However, the position is not a concern in a scaled copy image. Therefore, the figure did copy each length in scale.

Choice C. [tex]\boxed{TRUE}[/tex]

The figure given as choice C seems to be larger than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Choice D. [tex]\boxed{FALSE}[/tex]

The figure given as choice D seems to be larger and wider than the original image. Therefore, the figure did not copy each length in scale.

Choice E. [tex]\boxed{TRUE}[/tex]

The figure given as choice E seems to be smaller than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Therefore, the choices would be B, C, E, which would be the third choice.

Extra: A shortcut (lazy) way to do the question

As listed above, A and D are clearly not to scale since one is much thinner, one is much wider. Therefore, we can directly neglect choices that contain A and D, which would only leave us with the third choice.

Hope this helps!! :)

Kevin plays on the school baseball team. In the last 8 games, Kevin was at bat 30 times and got 7 hits. What is the experimental probability that Kevin will get a hit during his next time at bat?

Answers

Hi, there I hope you are having a great day :) your question Kevin plays on the school baseball team. In the last 8 games, Kevin was at bat 30 times and got 7 hits. What is the experimental probability that Kevin will get a hit during his next time at bat?

1. In the last 8 games the total number of Kevin was at the bat was 30 and the number of times in which he hit the ball was 7.

2. Now we do the experimental probability = P (Hit) = Number of hits divided by the number of Kevin at the bat.

3. So the answer would be 7/30

Hopefully, that helps you :)

What is the step by step explanation on how to solve 8 1/2 + 3 4/5? I already know the answer is 12.3 but I just need help on the how to do the work.

Answers

To do this, first add the whole numbers: 8 + 3 = 11. Set that aside for a moment.

To add the fractions, 1/2 + 4/5, you need a common denominator. With 2 and 5, you’d have an LCD of 10.

1/2 = 5/10

4/5 = 8/10

So 1/2 + 4/5 = 5/10 + 8/10 = 13/10

Now, 13 is bigger than 10, so 13/10 is the same as 1 and 3/10.

We’ll add that to the 11 we found back in the beginning and get 11 + 1 and 3/10 = 12 and 3/10 or 12.3.

Please help! Greatly appreciated sorry for really bad quality

Answers

The first answer.

Point P is at (50,-40) the distance from Q to P is 80 units which you can find by subtracting the x of Q (-30) from the x of P (50).
50-(-30)=80
It then tells you point R is vertically above point Q so you know your x value for R will be the same as Q.
Add your distance from Q to P of 80 units to the y value of Q because you are traveling up.
-40+80=40
R will have a point of (-30,40) and a distance of 80 units
