Answer:
3x = 6
Step-by-step explanation:
Combine:
6x + 5y =16
- (6x + 2y=10)
--------------------
3y = 6, so that y = 2 (We weren't actually asked to find the solution.)
Answer:
a reflection over the x-axis
Step-by-step explanation:
say you plotted (1,1) and the plotted (-1,1). The result would be a reflection over the x-axis.
Perimeter is 30
Area is also 30.
Add the numbers to get the perimeter and then use 1/2bh to get the area. <span />
Something percent of a number must be smaller than the number.
And also, 39% of a number is equal to 39/100 multiplied by the number.
Thus:
39/100 * 1200
39/1 * 12
468
Answer:
b) use a two-sided test instead of a one sided test.
Step-by-step explanation:
If we are using a significance level of 0.05, then the two-tailed test assigns half alpha to test for statistical significance in one direction and half alpha to test statistical significance in the other direction. This implies that .025 is present in each tail of the test statistical distribution. When using the two-tailed test, regardless of the direction of the relationship you assume, we test the possibility of the relationship in both directions.
