Answer:

7c - 11

Step-by-step explanation:

To solve this, you are going to need to add like terms.

Since 5 and 2 both have a "c" next to them, you can add those together to equal 7c.

Then, since -13 and 2 do not have a "c", you can combine those together to equal -7.

Since there is no = , the closest you can get to solving this equation would then be 7c - 11.

Hope this helped!

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,

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

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

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

Hence, the probability for the first child to have Galactosemia is $\frac{1}{24}$
