Answer:

Area: 40 cm²

Perimeter: 24 cm

Step-by-step explanation:

<u>Area of Triangle</u>

To find the area of a triangle, you need to do 1/2bh.

b*h = 80. Divide by 2, you get 40 cm²

<u>Perimeter of Triangle</u>

Just add up all the sides! 10 + 8 + 6 = 24 cm!

kap26 [50]

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.
