The variance of the value 7,15,11,1,11 is 22.4
To divide fractions, cross multiple it, 7*9 and 12*5 =
7*9 = 63, 12*5 = 60
63/60
this can be simplified to 21/20
1 and 1/20 as a mixed fraction
1.05 as a decimal
Using the distributive property, you’ll get the equation 56i+63.
You’ll distribute (multiply) 7 to 8i, and 7 to 9
Since ∝ < β you can throw out answers C and D. Using the relationship of sine and cosine being complementary angles you can plug in the two smallest values. Out of those two for 13° you get sin18°=cos72° and 13°+72°=90°, meaning these two angles are complementary.
