Answer:
1.98
Step-by-step explanation:
In this problem, we are:
Given: ∠D = 26°, Hypotenuse (DF) = 4.5
To solve: EF
Now through the given, we are to focus on point D to solve for EF.
We need to find the relationship of point D to DF and EF.
The relationship here is sine.
Reason:
Through point D, DF is the hypotenuse and EF is the opposite side.
So let's solve this simply through algebra,
sin =
sin(26°) =
0.44 =
0.44 × 4.5 = EF
1.98 = EF

Answer:
Mean is the sum of all the results included in the sample divided by the number of observations.
Explanation:
Suppose we have the score of 5 randomly selected students in a class.
The scores are:
Now the mean of the 5 randomly selected students will be:
Therefore, the mean is 57.6
