Answer:

A. (4, 12)

Step-by-step explanation:

Adding the second equation to twice the first will eliminate y.

2(10x +2y) +(3x -4y) = 2(64) +(-36)

23x = 92 . . . . . . . . simplify

x = 4 . . . . . . . . . divide by 23

This value matches choice A: (4, 12).

Let's do the trig part first, then the calculus. First we simplify the integrand.

$\cot^3 x \sin ^3 x=\dfrac{\cos^3 x}{\sin^3 x} \sin^3 x= \cos^3 x$

The triple angle formula is:

$\cos 3x = 4 \cos^3 x - 3 \cos x$

$\cos^3 x = \frac 1 4 (\cos 3x + 3 \cos x)$

Now we can integrate:

$\displaystyle \int \cot^3 x \sin^3 x \ dx = \int \cos^3 x\ dx= \int \tfrac 1 4 (\cos 3x + 3 \cos x)\ dx$

$=\frac 1 4 (\frac 1 3 \sin 3x + 3 \sin x) + C$

$=\frac 1 {12} \sin 3x + \frac 3 4 \sin x + C$

A diner asked its customers, 'Did you cook dinner last night?' The results on the survey are shown in the table below: Male Fema

Vinil7 [7]

The total number of both men and women surveyed was 305+279+152+459= 1195. Of this total, 279 women cooked dinner so 279/1195=0.23. This would compare with men which would be 305/1195=0.26 or slightly higher probability.
