Answer:

A. The probability that the student is left-handed, given that the

student is a boy

Step-by-step explanation:

Given

Number of students = 30

Number of boys = 16

Number of girls = 14

Left handed boys = 3

Left handed girls = 2

Suppose that there are two events A and B; conditional probability of an event B is defined such as the probability that the event B will occur provided that event A has already occurred.

Looking at option A through D, the best option that fits the question is option A.

The reason is that;

The option presents the probability that a selected student is left handed provided that the selected student is a boy.

We can split this statement to 2 events;

Event A: Probability that a selected student is a boy

Event B: Probability that a selected student is left handed

The sales tax in your state is 5% if a car costs $24,600 what is the total cost including tax?
Svetach [21]
<h2>Greetings!</h2>

Answer:

$25830

Step-by-step explanation:

If 100% of the car price is 24,600 , then you can imagine that extra 5% being added to this

100 + 5 = 105

So you need to find what 105% of the cost was.

To do this you can use the percentage formula:

Amount x \frac{percentage}{100}

Now, you can simply plug the values into this

24,600 x \frac{105}{100}

24600 x 1.05 = 25830

<h3>So the total cost including tax would be $25830!</h3><h3 /><h2>Hope this helps!</h2>

Need brief explanation about why false is correct
anyanavicka [17]

<u>We are given the equation:</u>

(a + b)! = a! + b!

<u>Testing the given equation</u>

In order to test it, we will let: a = 2 and b = 3

So, we can rewrite the equation as:

(2+3)! = 2! + 3!

5! = 2! + 3!

<em>We know that (5! = 120) , (2! = 2) and (3! = 6):</em>

120 = 2 + 6

We can see that LHS ≠ RHS,

So, we can say that the given equation is incorrect

What’s the answer to this question
Andreas93 [3]

Answer:

ab

Step-by-step explanation:

When all of the variables are the same in a problem, think of them as the same term. They can be added and subtracted just as you would add and subtract normal numbers.

For example if I have 5 bananas on a table and take away 3 bananas. I only have two bananas left (2b). It's the same when there are variables!

Subtract 9 from 3:

-6ab+7ab

Add -6 to 7:

ab

Your final answer is ab!

Line a intersects both lines c and d.
Line a is a transversal to lines c and d.
Angles 10 and 14 are corresponding angles.
Since corresponding angles are congruent, lines a and c are parallel.
Line b has nothing to do with this question.
Answer is choice A.
