Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y
The probability would be 1/6 for each number but for this is would be 2/6
Answer:
Step-by-step explanation:
hello,
from the question, we were not given the P-value. If the test result were statistically significant, this means that P < 0.05 , thus we will reject the null hypothesis. if P < 0.05, then we are saying that the probability that the teaching method affected the students in their final exams is less that 5%. hence we reject the null hypothesis.
on the other hand if the test result is not statistically significant, this means that the P-value, P > 0.05, thus we will fail to reject the null hypothesis because the probability that the teaching method affected the students performance in their final exam is greater than 5%.
Answer:
373/500 = 0.746
Step-by-step explanation:
373 out of 500 is represented by the fraction 373/500.
This value is easily converted to a decimal number by multiplying numerator and denominator by 2:
(373×2)/(500×2) = 746/1000 = 0.746
_____
You can also divide 373 by 500 using a calculator to get the decimal result.

First is dividing
56 ÷ 34 = 56/34
56/34 = 28/17
56 ÷ 2 = 28
34 ÷ 2 = 17
Then multiply by y
28/17 × y = 28/17·y = 28y/17 or 28/17y
At last, you add 12
28y/17 + 12 = 28y/17 + 12
Your answer is: 28y/17 + 12
Hope this helps :)
