A bag contains 5 red marbles, 6 blue marble, 3 green marbles, 4 black marbles, 2 yellow marbles. A marble will be drawn from a bag and replaced 200 times. What is a resonanle predition for each times a yellow or green marble will be drawn

Answers

Answer 1

Answer:

50 times

Step-by-step explanation:

Red = 5 ; blue = 6 ; green = 3 ; black = 4 ; yellow = 2

Total number of marbles :

(5 + 6 + 3 + 4 + 2) = 20

Probability of drawing a yellow or green marble :

P(yellow) + p(green)

(2 / 20) + (3 / 20)

5 / 20

Hence, Number of times from 200 draws :

(5 / 20) * 200

= 50

3 + 2n

Step-by-step explanation:

2 + 1 = 3.

2n cannot be added into this because it has a letter in front of it. Therefore, it stays on its own.

1 and 3 are like terms, and because there are no more variables, the 2n will stay alone :)

Otis is packing two gift boxes in a shipping carton. The rest of the space in the carton will be filled with packing pellets. What is the volume of the space that needs to be filled with packing pellets?

Answers

Answer:

[tex]V_3 = 1916in^3[/tex]

Step-by-step explanation:

Given

See attachment for gift items and the shipping carton

Required

Determine the volume of the empty space

First, we calculate the volume of the carton.

[tex]V = LWH[/tex]

From the attachment

L = 16; W =11 and H =13

So:

[tex]V = 16*11*13[/tex]

[tex]V = 2288[/tex]

Next, calculate the volume of the blue wrap

[tex]V = lwh[/tex]

From the attachment

l = 9; w =9 and h =2

So:

[tex]V_1 = 9 * 9 * 2[/tex]

[tex]V_1 = 162[/tex]

Next, calculate the volume of the pink wrap

[tex]V = lwh[/tex]

From the attachment

l = 6; w =5 and h =7

So:

[tex]V_2 = 6*5*7[/tex]

[tex]V_2 = 210[/tex]

The volume of the rest space (V3) is then calculated as:

[tex]V_3 = V - V_1 -V_2[/tex]

[tex]V_3 = 2288 - 162 -210[/tex]

[tex]V_3 = 1916[/tex]

Hence, the rest volume is 1916in^3\

Expand and combine like terms.
(765 – 46)(765 + 46)

Answers

Answer:

587,341

Step-by-step explanation:

(I'm hoping this is what you mean by expand)

(765 – 46)(765 + 46)

First, multiply 765 by 765 = 585,225

Second, multiply 765 by 46 = 35,190

Third, multiply -46 by 765 = -35,190

Fourth, multiply -46 by 46 = -2,116

The second and third answers (35,190 and -35, 190) will cancel each other out. Then, just subtract -2,116 from 585,225.

585,225 - (-2,116) = 585,225 + 2,116 = 587,341

well if u think abut adding them or multyplying them then if u round all the numbers to the nearest 100s then u will get ur answer witch is 122 is ur answer

Step-by-step explanation:

She needs altogether 2 2/4. that is 2 wholes and 2/4 fraction. if we consider using 1/4 cup, 1 whole is made of four quarter cups. Therefore 2 wholes require eight quarter cups. Then theres a remaining fraction of 2/4 which is equivalent to two quarter cups. 1/4 + 1/4 = 2/4. Therefore altogether 8 + 2 = 10 of the 1/4 cups are required for the recipe. 10 of 1/4 cups are needed is this right? Yes or no

Answers

Answer:

Yes

Step-by-step explanation:

According to the analysis;

There are four 1/4 cups in one whole

There are eight 1/4 cups in two wholes

Then the fraction 2/4 = 1/4 + 1/4 Hence there are two 1/4 cups in 2/4.

Altogether we have the fraction 2 2/4 as 8 + 2 = 10 measures of 1/4 cups

To confirm, 10 * 1/4 = 2 2/4

Therefore, the analysis is correct.

The greatest common factor(GCF) of LaTeX: x^7,\:x^3,\:x^5\:is\:_{ }__________.

Answers

Answer:

x^3

Step-by-step explanation:

We are to find the greatest common factor of x^7, x^3 and x^5

x^7 = x^3 * x^4

x^3 = x^3 * 1

x^5 = x^3 * x^2

From both factors, we cam see that x^3 is common to the three, hence the GCF is x^3
