The probability of Jamie picking a blue marble is greater. The ratio of this probability would be 7:3

Hi Melanie!

This problem involves proportion.

Let x be the unknown, which is the height of the building.

height of pole = height of the building

height of the shadow height of the shadow

3.3 m = x

1.78 m 49. 75 m

Solve for x.

(3.3 m) (49.75 m) = x

1.78 m

92.2331460674 = x

Rounded to the nearest meter, the building is 92 meters high.

Hope that helps.

The fraction bars are not coming out (Underline), I don't know why... but yeah, that is the answer.

Mae has a number cube with 6 sides that are numbered 1 through 6. What is the probability that Mae will roll an odd number?

Stels [109]

Answer:

C) $P(E) = \frac{3}{6}$ <u></u>

The probability that Mae will roll an odd number

<u></u> $P(E) = \frac{3}{6}$ <u></u>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that Mae has a number cube with 6 sides that are numbered 1 through 6.</em>

<em>n(S) = { 1,2,3,4,5,6,} = 6</em>

<em>Let 'E ' be the event of odd numbers</em>

<em>Mae will roll an odd number</em>

<em>n(E) = {1, 3, 5} = 3</em>

<u>Step(ii):-</u>

<u>The probability that Mae will roll an odd number</u>

<u></u> $P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}$ <u></u>

<u></u> $P(E) = \frac{3}{6}$ <u></u>
