Answer:
D. Use the Distributive Property. You clear the parentheses and then solve the two-step equation.
Step-by-step explanation:
To solve the given expression;
2(w − 3) = 5
Use the Distributive Property. You clear the parentheses and then solve the two-step equation;
Is the most appropriate procedure to follow:
2(w − 3) = 5;
Distributive property will clear the parentheses;
2w - 6 = 5
Then add 6 to both sides;
2w -6 + 6 = 5 + 6
2w = 11
Then divide both sides by 2;
w =
Answer:
(i) The student who weighed the rock 20 times.
Step-by-step explanation:
The margin of error of a confidence interval is:
In which z is related to the confidence level, is the standard deviation of the population and n is the size of the sample.
From the equation above, the larger the size of the sample, the lower the margin is, that is, the narrower the interval is.
In this question:
A student weighed the rock 20 times and other the 5. From above, the one who weighed the rock 20 times will have the more precise interval.
So the correct answer is:
(i) The student who weighed the rock 20 times.
Answer:
0.20 dollars/mile
Step-by-step explanation:
The slope actually has units. It has the meaning of 20 cents per mile. The units are cents per mile.
But it can also be 0.20 dollars/mile which is probably the way you should interpret it in a math class. That way it matches the units of the 50 which is for certain in dollars.
