Answer:
w= 9 3/4
Step-by-step explanation:
4 1/5 =21/5
13 19/20= 279/20
w+21/5 + 279/20
-21/5 -21/5
w+39/4
w=9 3/4

Answer:
a = 29/46
b= - 9/46
Step-by-step explanation:
<u>Given:</u>
- (5 + 2√3)/(7 + √3) = a - √3b
<u>Rationalizing the left side:</u>
- (5+2√3)(7-√3)/(7+√3)(7-√3) =
- (35 + 14√3 - 5√3 - 2√3²)/(7² - √3²) =
- (35 - 6 + 9√3)/(49 - 3) =
- (29 + 9√3)/46 =
- 29/46 + √3 (9/46)
<u>Comparing the left and right sides:</u>
- a - √3b = 29/46 + √3 9/46
- a = 29/46
- b = - 9/46
Answer:
The population mean is of 6.1667.
Step-by-step explanation:
Total sample size:
26 + 54 + 86 + 26 = 192
Mean:
To the mean is the sum of the midpoint of the class frequencies multiplied by its frequency(mean of 2 to 4 is 3, 4 to 6 is 5 and so on...). So

The population mean is of 6.1667.
