I’m not that sure if the numbers you provided are the ones I am supposed to be adding or the x’s in the graph but here’s an answer for both

Numbers: 150
X:10

If I didn’t understand what to add, please let me know

The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.

Phil has 7 green marbles and 3 purple marbles in a bag. he removes a marble at random, records the color, puts it back, and then

Lesechka [4]

The probability of selecting a green marble in one turn is 7/7+3 which is 7/10. For 3 turns, we will do $\frac{7}{10} * \frac{7}{10} * \frac{7}{10} = \frac{343}{1000}$

Am I do this correctly?

love history [14]

You have the right idea. You multiply the exponents. However, you did not multiply the denominators 6 and 6 to get 36

So you should have 12/36 reducing to 1/3 as your final exponent

Therefore, the answer is 6^(1/3) which is the same as the cube root of 6

Side note: you don't need to turn 2/3 and 1/2 into fractions with a denominator of 6. You can multiply straight across and simplify

(2/3)*(1/2) = (2*1)/(3*2) = 2/6 = 1/3

Find the values of

astra-53 [7]

The values of AB, BC, CD and AD are the distance between their endpoints.

<em>The lengths cannot be determined.</em>

I've attached the required diagram.

The length of the segments cannot be calculated; so, I will give the steps to calculate the lengths.

<em>Draw a straight through each endpoint</em>
<em>Measure the length of straight using a ruler.</em>
<em>Record each length</em>

<u>Approximate to the nearest eighth of an inch.</u>

To approximate to the nearest eighth of an inch means that, you approximate to the nearest 0.125

Assume the length of AB is:

$AB = 4.51$

<u>The eighths of an inch are: </u>

0.125, 0.250, 0.375, 0.500, 0.625, 0.750, 0.875, 1.000

<em>0.51 is between 0.500 and 0.625, but it is closer to 0.500.</em>

So, the approximated value would be

$AB = 4.500$

Assume BC is:

$BC = 4.200$

<em>0.200 is between 0.125 and 0.250, but it is closer to 0.125.</em>

So, the approximated value would be

$BC = 4.250$
