Remember distributive property
a(b+c)=ab+ac
we can ervers it
6(31)+6(4)-6(15)=6(31)+6(4)+6(-15)=6(31+4-15)=6(20)=120
-2x + 8 = -4x + 1
- 1 -2x
7 = -6x
—
-6x
7/-6 or -7/6
Answer:
The answer is "No, There are more than two possible outcomes on each trial of the experiment
".
Step-by-step explanation:
When various ice cream products are known. This might surpass 2 brands or more. Thus the number of different results varies considerably.
BINOMIAL DISTRIBUTION:
An investigation with a set set of individual tests, each only with two possible results.
Four conditions are met by the binomial experiment
- The set of indicators is fixed.
- Each attempt is autonomous.
- 2 potential results exist only.
- In each and every test, the probability of each outcome remains unchanged.
Answer:the company bought 12 computers and 4 printers.
Step-by-step explanation:
Let x represent the number of computers that the company bought.
Let y represent the number of printers that the company bought.
The company buys a total of 16 machines. It means that
x + y = 16
Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that
550x + 390y = 8160 - - - - - - - - - - 1
Substituting x = 16 - y into equation 1, it becomes
550(16 - y) + 390y = 8160
8800 - 550y + 390y = 8160
- 550y + 390y = 8160 - 8800
- 160y = - 640
y = - 640/ - 160
y = 4
Substituting y = 4 into x = 16 - y, it becomes
x = 16 - 4
x = 12
