Answer:
34.5
Step-by-step explanation:
Given the data:
X : 18; 18; 21; 22; 25; 26; 27; 29; 30; 31; 31; 33; 36; 37; 37; 41; 42; 47; 52; 55; 57; 58; 62; 64; 67; 69; 71; 72; 73; 74; 76; 77.
The 37th Percentile :
37/100(n + 1)th term
n = sample size = 32
Therefore,
0.37(32 + 1)th term
0.37(33)th term = 12.21 th term
(12th + 13th) term ÷ 2
(33 + 36) / 2
69 / 2
34.5
The 37th percentile is 34.5

3/4 - 4x + 1/2x - 1/2 + 1/2x Combine the like terms to simplify. Show your work
If you mean,
[tex] \frac{3}{4} - 4x + \frac{1}{2} x - \frac{1}{2} + \frac{1}{2}x[/tex]
Then the answer would be,
[tex] \frac{1}{4} - 3x[/tex]
But if you mean,
[tex] \frac{3}{4} - 4x + \frac{1}{2x} - \frac{1}{2} + \frac{1}{2x} [/tex]
Then the answer would be,
[tex] \frac{1}{4} - 4x + \frac{1}{x} [/tex]
