Answer:
19.5
Step-by-step explanation:
15 + 4.5 = 19.5
24 - 4.5 = 19.5
Ok, so you have a right angle, a given angle, and a given side for the left triangle. We are going to call angle 47° angle A. So angle A=47°, the side connecting the two triangles is directly opposite A making it side "a". We are calling the right angle C and the hypotenuse (the longest side which is 11) "c". So, Sin A=a/c and since we don't have "a" we multiply both sides by "c" changing it to (c Sin A)=a. 11•Sin(47°)=a
11•(0.7313537016)=a
8.044890718=a
Solution :
Given :
Sample mean,
Sample size, n = 40
Standard deviation, s = 83.2
∴ The null hypothesis is
Alternate hypothesis is
Test statistic :
z = 0.813
Now at α = 0.05, for a right tailed,
Since, , we fail to reject the null hypothesis.
The last two choices are appropriate.
Both give you f(1) = 7, f(2) = 9.50, f(3) = 12.00, ... as they should.
