There aren't any like terms so it would be
x+2y+3z
The probability of getting all 5 right would be 1/<span>3125
This is because each question has one choice. Making it a 1/5 chance for each question.
Now if you combine if you add the rest you will have to calculate.
You would do the calculation by multiple the chance for a correct answer for each question together.
1/5 x 1/5 x 1/5 x 1/5 x 1/5 = 1/3125

Answer:
0.4, 0.004, 0.004
Step-by-step explanation:
The "what" in each case is found by dividing the target value by 10. That is accomplished by moving the decimal point one place to the left.
4/10 = 0.4 ⇒ 10 times 0.4 = 4
0.04 and .04 are exactly the same value, so the last two on your list are the same:
0.04/10 = 0.004 ⇒ 10 times .004 = 0.04
Answer:
28.45
