Answer:

sin( -∅ )

- 1 / csc ( ∅ )

1 / csc ( -∅ )

Step-by-step explanation:

Since sin(x) is and odd function (a function where f(-a) = f(a) ).

-sin( ∅ ) = sin( -∅ )

On the other hand, we know that sin( ∅ ) = 1 / csc ( ∅ )

Another odd function, so the same as before applies.

-sin( ∅ ) = -1 / csc ( ∅ )

-sin( ∅ ) = 1 / csc ( -∅ )

Chicken eggs can be categorized as large if they weigh at least 2 ounces. Clare weighs 48 large eggs and finds that they have a
oee [108]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Large eggs : ≥2 ounces

Mean of 48 large eggs = 2.1 ounces

Mean absolute deviation = 0.08 ounces

0.08 ounces here is the mean absolute deviation of the 48 large eggs weighed, meaning that:

The average of the sum of the absolute differences in each individual egg and the mean value of all eggs weighed is 0.08.

This means that the average difference, variability or deviation in the weight of large eggs weighed is 0.08 ounces around the mean value of all eggs weighed.

Mean Absolute Deviation (MAD) :

Σ|xi - mean| / n

xi = each individual value

n = number of values

A cistern is leaking 0.25 liters of water per minute. Approximately how many gallons of water is the cistern losing per hour? (P
nikklg [1K]

The cistern is losing approximately 3.963 gallons of water per hour.

<u><em>Explanation</em></u>

A cistern is leaking 0.25 liters of water per minute.

<u>We know, 1 gallon = 3.785 liters</u>

So, 0.25 liters = \frac{0.25}{3.785}=0.06605... gallons

That means, the cistern is losing 0.06605....gallons of water per minute.

So, the amount of water losing in 1 hour or 60 minutes =(0.06605...*60) gallons= 3.963 gallons <em>(Approximately)</em>
