Answer:

a. Probability of landing on red = \frac{1}{5}

b. <em>See Explanation</em>

Step-by-step explanation:

Given

A Spinner

Number of section = 10 (equal sized)

Number of red section = 2

Required

- Probability of landing on red

- Describe the probability in words

Calculating the probability of landing on red

The formula used in calculating probability is as follows

Probability = Number of required outcomes / Number of possible outcomes

In this case, the number of required outcomes is the number of red section.

Hence, number of required outcomes  = 2

And the number of possible outcomes is the total section of the spinner

Hence, Number of possible outcomes = 10

By Substitution

Probability of landing on red = \frac{2}{10}

Probability of landing on red = \frac{1}{5}

Describe the probability in words

From (a) above, we have that the probability of the spinner landing on color red is \frac{1}{5}

This means that, for every five times, you spin the spinner, it's likely that one of the outcomes will be red.

A side of the triangle below has been extended to form an exterior angle of 159º. Find the value of x.
xenn [34]

Answer:

x = 69

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles in a triangle

x+90 = 159

Subtract 90 from each side

x +90-90 = 159-90

x =69
