Answer:

52√3 ft²

Step-by-step explanation:

sin 60° = (√3) / 2 = h/8

h = 8 x (√3) / 2 = 4√3

cos 60° = 1/2 = a/8

a = 4         b = 15-4 = 11

area = left triangle + right rectangle

area = (4*4√3) / 2 + 11*4√3

        = 8√3 + 44√3

        = 52√3

Point (k, -3) lies on the line whose equation is x-2y=-2. What is the value of k?
natita [175]

Answer:

Substitute, <em><u>y = -3</u></em> and <em><u>x = k</u></em> on the equation.

=> k - 2×(-3) = -2

=> k = -2 + (-6)

=> k = - 8

A four-sided die is rolled repeatedly, until the first time (if ever) that an even number is obtained. What is the sample space
Andrew [12]

Answer:

Sample space by its definition is termed as the list of all the possible outcomes of an experiment.

Therefore, the sample space for this experiment rolling a four-sided die will be: {1, 2, 3, 4}

Step-by-step explanation:

When you roll a a four-sided die, number of dots on uppermost face is said to be an outcome.

For example,  whenever a four-sided die is rolled we can get either 1, 2,3 or 4 dots on the upper most face as an outcome.

As we know that rolling a four-sided die will bring the following possible outcomes: {1, 2, 3, 4}

Possibilities of the number being even (2 and 4) = 2

Probability of the number being even = 2/4 = 1/2

Sample space by its definition is termed as the list of all the possible outcomes of an experiment.

As we have already determined that rolling a four-sided die will bring the following possible outcomes: {1, 2, 3, 4}

Therefore, the sample space for this experiment will be: {1, 2, 3, 4}

Keywords: sample space, 4-sided dice
