Suppose Mike has a dresser with 3 tan pants, 5 jeans, 2 black pants, and 3 gray pants. He also has 2 brown shoes, 3 black shoes, and 2 blue shoes. If he randomly chooses a pair of pants and shoes, what is the probability that both are black? Give your answer as an exact fraction and reduce the fraction as much as possible.

Answers

Answer:

Probability of choosing a black pair of pants and shoes $= (6)/(91)$

Step-by-step explanation:

Given:

Total number of pants Mike has = $\textrm{ 3 tan pants + 5 jeans + 2 black pants + 3 gray pants = 13 pair of pants}$

Probability of randomly choosing a pair of black pants = $\frac{\textrm{Number of Black pants}}{\textrm{Total number of pants}} = (2)/(13)$

Total number of shoes Mike has = $\textrm{ 2 brown shoes + 3 black shoes + 2 blue shoes = 7 pairs of shoes}$

Probability of randomly choosing a pair of black shoes = $\frac{\textrm{Number of Black shoes}}{\textrm{Total number of shoes}} = (3)/(7)$

Probability of choosing a black pair of pants and shoes = $(2)/(13)* (3)/(7) = (6)/(91)$

Linda found that the cost to get a swimming pool installed in her backyard is a linear function of the pool's area. A swimming pool with an area of 1,000 square feet can be installed for $50,000, whereas the installation of an 800 square foot swimming pool costs $35,000. Select the correct graph that models the given relationship.

Answers

Final answer:

The cost to install a swimming pool as a function of its area can be modeled by the linear equation y = 35x + 15,000, where y is the cost and x is the area in square feet. The cost increases by $35 per extra square foot of area.

Explanation:

The first step in modelling this scenario is to identify the slope of the linear relationship between the pool's area and its cost. The slope can be determined using the formula:

m = (y2 - y1) / (x2 - x1)

Where:

Applying these numbers to the formula gives a slope (m) equal to $35 per square foot.

Next, we can determine the y-intercept (b) of the equation by substituting one of the points and the calculated m into the equation y = mx + b:

$50,000 = $35 * 1000 + b, solving for b gives b = $15,000.

Therefore, the linear equation that models this situation is y = 35x + 15,000. The graph of this equation is a straight line that starts at (0, 15,000) and increases with a slope of 35. Every increase in pool area of 1 square foot increases the cost by $35.

Answer:

$35,000

Step-by-step explanation:

if $50,000 is to install an area of 1,000 square feet swimming pool and $35,000 can be used to install an 800 square foot swimming pool I think the best graph model is 800 square feet for $35,000 for a cost cut of $15,000 is a good bargain

Can you help me simplify it?
