Use Long Division to find the answer. Please show all steps!
ValentinkaMS [17]

Answer:

The answer to your question is 2x² + 3x +  Remainder (17x - 7)/ ( 2x⁴  +  3x³  - 4x²  + 5x - 7)

Step-by-step explanation:

                             2x² + 3x

             x² - 4     2x⁴  +  3x³  - 4x²  + 5x - 7

                          -2x⁴              + 4x²

                            0      + 3x³   + 0    + 5x

                                     - 3x³             +12x

                                        0                +17x - 7

Quotient = 2x² + 3x

Remainder = 17x - 7

Solution  = 2x² + 3x + (17x - 7)/ ( 2x⁴  +  3x³  - 4x²  + 5x - 7)

Process

1.- Divide the first term of the divident by the first term of the divisor and place the result above the first term of the divident.

2.- Multiply the result of the division (2x²) by the first term of the divisor and change the sign of the result.

3.- Multiply the result (2x²) by the second term of the divisor and place the result below the like term.

4.- Add the results.

5.- Continue with this process until the remainder be lower than the divisor.

A shipment of 24 electric typewriters are rejected if 3 are checked for defects and at least 1 is found to be defective. Find th
Maslowich

Answer:

You keep them if you test 3 and all pass.

There are 18 good ones and 6 bad (making 24)

Chance of first passing is 18/24

If it passes, there are now one less good and one less total.

Chance of second passing is 17/23

If it passes, there are now one less good and one less total.

Chance of second passing is 16/22

Total is (16 x 17 x 18) / (22 x 23 x 24) = about 0.4 (0.403162055 is you really want to know).

So probability all are ok is 0.4

Thus probability you find at least one bad one is 0.6

Hope this helps you out!

13 + (15) = 28


Because you always add the numbers in the parenthesis so 12 + 3 = 15 and 13 + 15 = 28
