Part A: There are five buttons in all in all in the given item. The item above can be answered through the fundamental principles of counting. 

There are 5 items to choose from during the first pick. Because the shape can be returned and picked again, there are also 5 items to choose from in the second pick. Multiplying them,
                               n = 5 x 5 = 25
Therefore, the sample size for the compound event is equal to 25.

Part B: The same concept can be used in this part of the item; however, instead of 5 there are 6 buttons to choose from.
                              n = 6 x 6 = 36

Hence, the sample size of this picking process is 36.

Solve the following system of equations and show all work.<br> y = 2x^2 +9x<br> y = 4x + 25
Genrish500 [490]

Answer:

x = 5/2 thì y = 35 và x = -5 thì y = 5

Step-by-step explanation:

thay y = 4x + 25 vào phương trình y = 2x ^ 2 + 9x ta có:

4x + 25 = 2x ^ 2 + 9x

⇒2x ^ 2 + 5x - 25 = 0

⇒ x = 5/2 và x = -5

thay x = 5/2 vào phương trình y = 4x + 25 ⇒ y = 4*(5/2) + 25 = 35

thay x = -5 vào phương trình y = 4x + 25 ⇒ y = 4*(-5) + 25 = 5

A question from my math class:
valina [46]

Answer:

A) $29.68

B) $5.60

Step-by-step explanation:

<u>Part A Explanation)</u>

To find the total cost including tax, you must multiply the total cost by .06 because .06 out of 1 is 6%. <em>Quick explanation on percentages.</em>

<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>

28.00 + (28.00 * .06) = 29.68

<u>Part B Explanation)</u>

This is asking only for the tip, not including the total cost. However, we need the total cost to calculate the tip.

28.00 * .20 = 5.6

<em>.20 out of 1 is 20%</em>
