You always want the period to the right of the first number meaning you’ll start from there counting backwards because it is negative.
Answer:
The solution is going to be the point where the two lines on a graph intersect.
Step-by-step explanation:
The solution of a system is going to be a ordered pair that satisfies all of the equations in the system. This translates to the lines intersecting on a graph since they all go through the same ordered pair.
Answer:
Size 50
Step-by-step explanation:
You should choose the larger sample size. This is because if you take the mean, it will help to cancel out outliers. For instance, most people exercise half an hour. With sample size of 10, there might be one person who doesn't exercise, thus dragging down the mean. A larger sample size would have a greater ratio of "average" people.
Answer:
B
Step-by-step explanation:
Charla uses 2 cups of mix per 6 cups of water.
2/6 = 1/3
Rae uses 3 cups of mix per 7 cups of water.
3/7
To compare these fractions, we need to find the common denominator. In this case, it's 21.
1/3 = 7/21
3/7 = 9/21
9/21 is greater than 7/21, so Rae's lemonade will taste stronger.
Two numbers make up the factors of 1000. <span>In order that neither of the numbers be divisible by ten, each must contain powers of only one of the prime factors of 10, namely, 2 OR 5.</span>
So let's see what we can cook up. The obvious answer is
1000 = 10 * 10 * 10
1000 = 2*5 * 2*5 * 2*5
1000 = 2^3 * 5^3
1000 = 8 * 125 Are there any others?
I don't think so. The answer then comes to 8 + 125 = 133
You might argue that -8 * - 125 would also work. But the question says natural numbers not integers.
