Question 1328
Wool fat is unavailable and must be replaced by lanolin ($28\%$ water, $72\%$ wool fat). What amounts of lanolin and water are needed for the prescription: zinc oxide $2$ g, calamine $2$ g, wool fat $36$ g, water to $60$ g?
Correct Answer Logic:
Lanolin needed $= \dfrac{36}{0.72} = 50$ g. Water from lanolin $= 50 \times 0.28 = 14$ mL. Total water in formula $= 60 - 2 - 2 - 36 = 20$ mL. Additional water $= 20 - 14 = 6$ mL.

Question 1335
For a frequency distribution, the first three raw moments about \(x = 0\) given that \(\mu_1' = 1\), \(\mu_2' = 16\), \(\mu_3' = -40\) are about \(a=2\). The second raw moment about \(x=0\) is:
Correct Answer Logic:
Second raw moment about zero: \(\nu_2 = \mu_2' + a^2 + 2a\mu_1' = 16 + 4 + 2(2)(1) = 24\). Alternatively using \(\nu_2 = \mu_2 + \bar{x}^2 = 15 + 9 = 24\), confirming the answer.

Correct Answer Logic:
Let first term \(=a\), common difference \(=d\), number of terms \(=2k\). Sum of odd-positioned terms \(=k\left(a+\frac{(2k-1)d}{2}\cdot\text{...}\right)=40\), even terms \(=55\). Difference: \(kd=15\). Last \(-\) first \(=(2k-1)d=27\). From \(kd=15\) and \((2k-1)d=27\): dividing gives \(2k-1=\frac{27k}{15} \Rightarrow k=5\).

UNTOWARD: Choose the word most nearly opposite in meaning to this word.
Correct Answer Logic:
UNTOWARD means unexpected and inappropriate or inconvenient โ something that causes difficulty or is unfavorable.
