Step-by-step explanation:
Answer:
a) <em>Mean number of beans = 33.4 per coco pad</em>
<em>b) Standard deviation of the beans = 5.2 per coco pad</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
a)
Given data 30, 28, 30, 35, 40, 25, 32, 36, 38 and 40.
mean of beans
x⁻ = ∑x/n
![x^{-} = \frac{30+ 28+30+35+40+25+32+36+38 + 40.}{10} = 33.4](https://tex.z-dn.net/?f=x%5E%7B-%7D%20%3D%20%5Cfrac%7B30%2B%2028%2B30%2B35%2B40%2B25%2B32%2B36%2B38%20%2B%2040.%7D%7B10%7D%20%3D%2033.4)
<em>Mean number of beans per coco pad = 33.4</em>
<em>step(ii):-</em>
<em>b) </em>
<u><em>standard deviation</em></u>
<em>∑(xi - x⁻)² = (30-33.4)²+ (28-33.4)²+(30-33.4)²+(35-33.4)²+(40-33.4)²+(25-33.4)²+(32-33.4)²+(36-33.4)²+ (38-33.4)²+(40-33.4)²</em>
<em>On calculation , we get</em>
<em> ∑(xi - x⁻)² = 242.4</em>
<em>standard deviation </em>
<em> = </em>
<em></em>
<em>Standard deviation of the beans (σ) = 5.2 per coco pad</em>

Answer:
A) 20 degrees
Step-by-step explanation:
The sine of an angle is equal to the cosine of the angles complimentary angle.
First, we need to calculate how much money is the discount. We do that by multiplying 20% with 65$ = 20% * 65$ = 0,2 * 65$ = 13$
When we know how much money is the discount, we will subtract it from original value, and we will get the sale price of the tennis racket :
65$ - 13$ = 52$
