3tanx=-4
tanx=-4/3

Now

we know tan53=4/3

But it's negative

So tan is either in 2nd or 4th quadrant

For 2nd Quarter

x=π/2+53=90+53=143°

For 4th quadrant

x=3π/2+53=270+53=323°

Answer:

x = 143° and x = 323°

Step-by-step explanation:

Solving

3tanx = -4
tanx = -4/3
tan values are negative in the 2nd and 4th quadrant
The base value is x = 53°

In Quadrant II,

90° + 53°
⇒ x = 143°

In Quadrant IV,

270° + 53°
⇒ x = 323°

You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page

Sladkaya [172]

9.75 * 1.2 = 11.7
24.5 * .8 = 19.6

11.7+19.6= 31.3 minutes

hope this helped :)

Random samples of size 81 are taken from an infinite population whose mean and standard deviation are 200 and 18, respectively.

TiliK225 [7]

Answer:

d. 200 and 2

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
