Answer:
(a) Loss from selling 15 necklaces
(b) 
Step-by-step explanation:
<em>The question has missing details. (See the comment section for missing details)</em>
Given

Solving (a): Will she make a profit from 15 necklaces
To do this, we substitute 15 for b in 


The inequality is not true.
<em>Hence, she'll make a loss from selling 15 necklaces</em>
Solving (b): An expression that represents profit.
To do this, we solve for b in 
Collect Like Terms


Make b the subject


<em>This implies that to make a profit, she must sell more than 18 necklaces.</em>
Answer:

Step-by-step explanation:
Given
α = 2 and β = 3
As per Gamma distribution Function

Expanding the function and putting the given values, we get -

It says that the sum of the bases are 46 and the bases are the top and bottom, so that means that one base the top or bottom are 23 each so what do you think
Answer:
21 degrees
Step-by-step explanation:
To find this, we are going to use the appropriate trigonometric ratio
The right angle faces the length 22 which is the hypotenuse
The marked angle faces the length 8 which makes it the opposite
The trigonometric ratio that links the two is the sine
The sine is the ratio of the opposite to the hypotenuse
So, we have it that;
sine ? = 8/22
? = arc sine 8/22
? = 21 degrees
