castortr0y [4]

Answer:

The ratio of apartments to bathrooms in the building is 8 : 11

Step-by-step explanation:

We are given with,

Number of Apartments in the building = 48

Number of bathrooms in the building = 66

We have to find the ratio of number of apartments to the number of bathrooms.

$\frac{Number\:of\:apartments}{Number\:of\:bathrooms}=\frac{48}{66}=\frac{8}{11}$

Thus, Ratio is 8 : 11

Therefore, The ratio of apartments to bathrooms in the building is 8 : 11

When a scatterplot is created from a table of values, which statement is correct?

jeka94

Answer: A is correct option .It is possible for two points to have the same x-coordinate and the same y-coordinate.

Step-by-step explanation:

A scatter plot is a mathematical diagram or 2-dimensional data visualization using Cartesian coordinates to display values for two variables for a set of data by using dots to represent the values occurred for two different variables - one plotted along the x-axis and the other plotted along the y-axis. They show how variables are correlated thats why they are also called correlation plot. For example we have scatter plot with variables as study time and exam grade, so it can happen that 2 students study for same time and got same grade.

Therefore, It is possible for two points to have the same x-coordinate and the same y-coordinate.

John and Martha are contemplating having children, but John’s brother has galactosemia (an autosomal recessive disease) and Mart

Rina8888 [55]

<h2>Answer:</h2>

$Probability=\frac{1}{24}$

<h2>Step-by-step explanation:</h2>

As the question states,

John's brother has Galactosemia which states that his parents were both the carriers.

Therefore, the chances for the John to have the disease is = 2/3

Now,

Martha's great-grandmother also had the disease that means her children definitely carried the disease means probability of 1.

Now, one of those children married with a person.

So,

Probability for the child to have disease will be = 1/2

Now, again the child's child (Martha) probability for having the disease is = 1/2.

Therefore,

<u>The total probability for Martha's first child to be diagnosed with Galactosemia will be,</u>

$Probability=\frac{2}{3}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{4}\\Probability=\frac{1}{24}$

(Here, we assumed that the child has the disease therefore, the probability was taken to be = 1/4.)

<em><u>Hence, the probability for the first child to have Galactosemia is $\frac{1}{24}$ </u></em>
