Find x

The relationship between x, 47 and $17^{\circ}$ is:

$sin(17^{\circ}) = \frac{x}{47}$

i.e.

$sin(\theta) = \frac{Opposite}{Hypotenuse}$

Solving further:

$sin(17^{\circ}) = \frac{x}{47}$

Make x the subject

$x = 47 * sin(17^{\circ})$

$x = 47 * 0.2924$

$x =13.7428$

$x =13.7$ --- approximated

Write the polar coordinates (3, π) in rectangular form.

$\bf (\stackrel{\stackrel{r}{\downarrow }}{3}~~,~~\stackrel{\stackrel{\theta }{\downarrow }}{\pi })~~\begin{cases}x=rcos(\theta )\\y=rsin(\pi )\end{cases}\implies [3cos(\pi )~~,~~3sin(\pi )]\\[2em][3(-1)~~,~~3(0)]\implies \boxed{(-3,0)}$

3 = m/12 What is m? It is for math

JulsSmile [24]

Answer:

m is equal to 36.

Step-by-step explanation:

To get rid of division, all you need to do is multiply both sides of the equation by the denominator, which is 12 in this case:

$3 = \frac{m}{12}\\\\3 \times 12 = \frac{m}{12} \times 12\\\\36 = m$

So m is equal to 36

It is believed that 43% of the US population can play the piano, 28% can play the guitar, 15% can play the harmonica, 12% can pl

melomori [17]

Answer:

The smallest sample size to satisfy the conditions is n=500.

Step-by-step explanation:

The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

$np\geq10\\\\n(1-p)\geq10$

The largest sample size required will be for the minimum p or (1-p).

This happens to be the proportion that can play other instruments: 2%.

Then, we can calculate the minimum sample size as:

$np\geq10\\\\n(0.02)\geq10\\\\n\geq(10/0.02)\\\\n\geq500$
