Answer:

c=21, d=69, x=37

Step-by-step explanation:

159+c=180

c=21,

21+d=90

d=69,

3x+69=180

natita [175]

Answer:

Data is quantitative, data is categorical, data must be from a simple random sample, the data mut have normal distribution,

Step-by-step explanation:

When we make inference about one population proportion, we must ensure that the sample was taken randomly and observations follow a normal distribution. The sample size must be as large as possible with at least 10 counts of failures an 10 counts of successes. The individual observations must be independent. They must be quantified and categorized.

Quick question if I had a problem that was sin x = 18.9/20 =.945 how would I inverse sin of both sides ?

galben [10]

Answer:

The result is about 70.9 degrees

Step-by-step explanation:

Easy for a calculator. If you're not using a calculator, it's much more tedious!

There is an inverse sine key on your calculator, but you may have to press a key (likely labeled 2nd or INV) first. The attached image shows a TI-83 display. To get the inverse sine, I first pressed the yellow 2nd key, then the sin key.

Check MODE first to make sure you're measuring angles in degrees (if that's what you want!). Some calculators display angle mode with a small letter at the top of the display, D, R, or G usually.

The left side of the equation produces just x.

$\sin{x}=.945\\\\\sin^{-1}(\sin{x})=\sin^{-1}(.945)\\x=\sin^{-1}(.945) \approx 70.9^\circ$
