Answer:

Probability states the ratio of number of favorable outcomes to the total number of possible outcomes.

i.e,  probability = \frac{Number of favourable outcomes }{Total number of possible outcomes}

A bag contains:

Brown marble = 4

Green marbles = 3

Red marbles = 2

Purple marble = 1

Total number of possible outcomes = (4+3+2+1) = 10 marbles

P(Brown marbles) = \frac{4}{10}=\frac{2}{5} = 40\% = 0.4

P(Green marbles) = \frac{3}{10} = 30\% = 0.3

P(Red marbles) = \frac{2}{10}=\frac{1}{5} = 20\% = 0.2

and

P(Purple marbles) = \frac{1}{10}= 10\% = 0.1

Express each rate as a unit rate. <br> 70 miles in 2 hours
Radda [10]

<u><em>Answer:</em></u>

<u><em></em></u>

<u><em> 35 miles per hour</em></u>

<u><em /></u>

<u><em>Step-by-step explanation: Showing Work</em></u>

<u><em>This is a fraction equal to</em></u>

<u><em>70 miles ÷ 2 hours</em></u>

<u><em></em></u>

<u><em>We want a unit rate where</em></u>

<u><em>1 is in the denominator,</em></u>

<u><em>so we divide top and bottom by 2</em></u>

<u><em></em></u>

<u><em>70 miles ÷ 2</em></u>

<u><em>2 hours ÷ 2</em></u>

<u><em>= </em></u>

<u><em>35 miles</em></u>

<u><em>1 hour</em></u>

<u><em>= </em></u>

<u><em>35 miles</em></u>

<u><em>hour</em></u>

M is the midpoint of LN. What is the measure of LM= 3x and LN= 2x + 2, find LM.
raketka [301]

Answer:

LM = 1.5

LN = 3

Step-by-step explanation:

From the question given:

M is the midpoint of LN

LM = 3x

LN= 2x + 2

LM =.?

Next, we shall determine the value of x. This is illustrated below:

Since M is the midpoint of LN, it means that when we divide LN by 2 the result will be LM i.e

LN /2 = LM

With the above formula, we can obtain the value of x as follow:

LN= 2x + 2

LM = 3x

x =..?

LN /2 = LM

2x + 2/ 2 = 3x

Cross multiply

2 × 3x = 2x + 2

6x = 2x + 2

Collect like terms

6x - 2x = 2

4x = 2

Divide both side by 4

x = 2/4

x = 0.5

Finally, we can obtain LM and LN as follow:

LM = 3x

x = 0.5

LM = 3 × 0.5

LM = 1.5

LN= 2x + 2

x = 0.5

LN = 2(0.5) + 2

LN = 1 + 2

LN = 3
