Answer:

0.14

Step-by-step explanation:

Here, we want to find the probability that a student earns the grade of A

Mathematically, we have this as the frequency of A divided by the sum of all frequencies

From the question, the sum of all frequencies will be (5 + 10 + 15+ 3 +2) = 35

Now we place the frequency of A over this

This gives;

5/35 = 1/7 = 0.14

A) 5xy ×? = 15x²y² can someone explain​
Aleksandr [31]

Answer:

5xy*3xy=15x^2y^2

Step-by-step explanation:

Multiply 5*3 to get 15, and each x and y is squared, so 5xy needs another set of x and y to have two xs and ys in the final expression, so you multiply 5xy by 3xy to get your answer.

How to calculate velocity
zaharov [31]

Answer: Divide the total displacement by the total time.

In order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity. Example 1 (cont.): The car changed its position by 36 meters over 8 seconds.

A Coffee table was $129.99 and on sale for 20% off. The sales tax is 8.5%. How much do we save?
krek1111 [17]

Answer:

Step-by-step explanation:

Discount = 20% of 129.99

=\frac{20}{100}*129.99\\\\=25.998

= $26

Price after discount = 129.99 - 26 = $103.99

Tax = 8.5% of 103.99

=\frac{8.5}{100}*103.99\\\\=8.83915

= $8.84

Selling price including tax = 103.99 + 8.84

                                           = $112.83

Amount saved = 129.99 - 112.83

                        =$ 17.16

Please help!!!! :) !!!!!!!!
Musya8 [376]

Answer:

x = 3

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are equal, thus

x - y = x + 2 ( subtract x from both sides )

- y = 2 ( multiply both sides by - 1 )

y = - 2

and

4x + 2y = 2x - y

substitute y = - 2

4x - 4 = 2x + 2 ( subtract 2x from both sides )

2x - 4 = 2 ( add 4 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3
