Answer:
∠2 = 41°
Step-by-step explanation:
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
∠2 = 41°
Scientific notation has 1 number to the left of the decimal and is multiplied by 10 raised to the number of spaces the decimal is moved.
A) 5.9 x 10 ^ 9
B) 4 x 10 ^ -2
C) 1 km = 100,000 cm
4x 10^-2 x 100,000 = 4000 fireflies per km = 4 x 10 ^3 fireflies per km
5.9x 10^9 x 4x 10 ^3 = 2.4 X 10^13
A larger error variance making it difficult to estimate the partial effect of any of the independent variables on the dependent variable is True.
<h3>What is Variance?</h3>
This is used to measure how far a data is spread out and the effect independent variables has on the dependent ones.
When there is an error in the variance, the effect calculated is inaccurate which brings about difficulty in ascertaining it.
