A real estate agent is showing homes to a prospective buyer. There are ten homes in the desired price range listed in the area.

Citrus2011 [14]

Answer:

0.48% probability that all four are new

Step-by-step explanation:

The homes are chosen "without replacement", which means that after a home is visited, it is not elegible to be visited again. So we use the hypergeometric distribution to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

Total of 10 homes, so N = 10.

We want 4 new, so x = 4.

In total, there are 4 new, so k = 4.

Sample of four homes, so n = 4.

Then

$P(X = 4) = h(4,10,4,4) = \frac{C_{4,4}*C_{6,0}}{C_{10,4}} = 0.0048$

0.48% probability that all four are new

The table shows the height of a plant as it grows. what equation in point slope form gives the plants height at any time

Mazyrski [523]

Answer:

$y - 15 = 5(x-3)$

Step-by-step explanation:

Equation of a line:

The equation of a line, in point slope form, is given by:

$y - y_0 = m(x - x_0)$

In which the point is $(x_0,y_0)$ and m is the slope.

3/15

This means that $x_0 = 3, y_0 = 15$

$y - 15 = m(x - 3)$

Finding the slope:

Suppose we have two points. The slope is given by the change in the output divided by the change in the input.

3/15

5/25

Change in the output: 25 - 15 = 10

Change in the input: 5 - 3 = 2

$m = \frac{10}{2} = 5$

The equation is:

$y - 15 = 5(x-3)$

Janet bought 3/4 of a pound of apples, 1 1/2 pounds of bananas, and 2 1/4 pounds of grapes. She bought ____ pounds of fruit.

8_murik_8 [283]

Answer:

We have 3/4 plus 3/2 plus 9/4 pounds of fruit, so we get

12/4 + 3/2 pounds of fruit

and 3/2 can become 6/4, so we have 18/4 pounds of fruit, or 4 2/4 pounds, which can simplify into 9/2 or 4 1/2

A medical researcher has two petri dishes containing viruses. Dish A has a population density of 1.2 viruses per square millimet

Lyrx [107]

<h3><u>Answer;</u></h3>

= 3,391 viruses

<h3><u>Explanation;</u></h3>

The population density is 1.2 viruses per square millimeter.

This means, each square millimeter is occupied by a population of 1.2 viruses.

Therefore; for an area of 2,826 square millimeters, there will be;

= 2,826 multiplied by 1.2 viruses

= 2,826 × 1.2

= 3391.2 viruses,

and since we can have a fraction or decimal virus then the population would be <u>3391 viruses</u>
