X+10+10=8+10 is not equal to x=18. It must be x+20=18 x=-2
Answer:
4)X=23
5)x=15
Step-by-step explanation:
8x-77=3x+38
+77 -3x
5x=115
X=23
———
5x+3+9x-33=180
14x-30=180
+30
14x=180
X=15
Answer:
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
Step-by-step explanation:
The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.
In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.
Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
(f-g)(x) is equivalent to f(x) - g(x)
So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3
Hope this helps.
Answer:
4
Step-by-step explanation:
Take 1/5 divided by 4/5. In order to divide fractions you take the problem:
(4/5)/(1/5)
Then you flip the second fraction and multiply:
4/5 x 5/1
20/5
4
You could also just divide 4 by one, since the two fractions have the same denominator
