find the experimental probability and the theoretical probability.

Answers

Answer 1

The experimental probabilities of each outcome are given as follows:

Outcome of 1: 9/30 = 3/10.Outcome of 2: 5/30 = 1/6.Outcome of 3: 5/30 = 1/6.Outcome of 4: 7/30.Outcome of 5: 4/30 = 2/15.

The theoretical probability of each outcome is given as follows:

1/5.

How to calculate a probability?

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.

For the experimental probability, we consider the 30 trials in the table.

For the theoretical probability, we consider that each of the outcomes is equally as likely, hence the probability is given as follows:

p = 1/5.

Can someone please help me find the measure of the exterior angle.

Answers

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  

k = 140°

Solve 24 =y +17.5 y=

Answers

-6.5


17.5-24 you place the 24 near the 17.5 and make 24 a negative so the equation would be

y= 17.5-24

Answer:

[tex] \sf \: y = 6.5[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of y.

The equation is,

→ 24 = y + 17.5

Then the value of y will be,

→ 24 = y + 17.5

→ y + 17.5 = 24

→ y = 24 - 17.5

→ [ y = 6.5 ]

Hence, the value of y is 6.5.
