Answer:

Fraction =  13/20

Decimal =  0.65

Percent = 65%

Step-by-step explanation:

<em><u>Given:</u></em>

13 out of 20 emails in mail inbox are junk emails

<em><u>Solve for:</u></em>

The experimental probability that next email is junk

<em><u>Solution:</u></em>

Step 1: Define the formula for calculating the probability

P = number of elements/total number of elements

Step 2: Perform the calculation

The number of elements (junk emails) = 13

The total number of elements (all emails) = 20

=> P(obtain odd number in experiment) in fraction form = 13/20

=> P(obtain odd number in experiment) in decimal from = 0.65

=> P(obtain odd number in experiment) in percent form = 0.65 x 100 = 65%

Hope this helps!

What is the measure of ∠x
scZoUnD [109]

Answer:

∠x = 63°

Step-by-step explanation:

The exterior angle added with the measure of ∠BAC will equal 180, since they will form a straight line, so we can calculate the measure of ∠BAC:

128 + x = 180

x = 52

∠BAC = 52°

The angles in a triangle all add up to 180°, so we can set up another equation to find x:

52 + 65 + x = 180

117 + x = 180

∠x = 63°
