Answer:

The value of x is 55.6 unit.

Option (A) is correct .

Step-by-step explanation:

Now by using the trigonometric identity

$sin \theta = \frac{Perpendicular}{Hypotenuse}$

$\theta = 20^{\circ}$

Perpendicular = 19

Hypotenuse = x

Put in the identity

$sin\ 20^{\circ}= \frac{19}{x}$

sin 20° = 0.342

Put in the above equation

$x= \frac{19}{0.342}$

x = 55.6

Therefore the value of x is 55.6 unit.

Option (A) is correct .

19/x=sin 20
19/sin 20=x
x=55.5522836

The operating costs for each machine for one day have an unknown distribution with mean 1610 and standard deviation 136 dollars.

BabaBlast [244]

Answer:

20.27

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?

This is s when $\sigma = 136, n = 45$ . So

$s = \frac{136}{\sqrt{45}} = 20.27$

So the correct answer is:

20.27

Answer:

LQ = 5

Median = 6

Step-by-step explanation:

$\frac{n+1}{2}$ gives us 5.5, so we do the average of position 5 and 6. This gives us 6, so the median is 6.

Now we find the median of the bottom half of the numbers, which is 5, so the LQ is 5.

Now we find the median of the upper half of the numbers, which is 7, so the UQ is 7.

The heaviest freshwater fish caught in region A weighs 209 lb, and the heaviest freshwater fish caught in region B weighs 629 l

Colt1911 [192]

Answer:

$Region\ A= \frac{209}{2240}\\\\Region\ B= \frac{629}{2240}$

Step-by-step explanation:

The English ton, also known as the long ton, is equivalent to 2,240 pounds. Therefore, the fractional parts, of each of the two fish, of the English ton are:

Fish caught in region A:

$A= \frac{209}{2240}$

Fish caught in region B:

$B= \frac{629}{2240}$

Both fractions are irreducible.
