Answer:
\mu = 14.5\\
\sigma = 5.071\\
k = 1.084
Step-by-step explanation:
given that a statistician uses Chebyshev's Theorem to estimate that at least 15 % of a population lies between the values 9 and 20.
i.e. his findings with respect to probability are

Recall Chebyshev's inequality that

Comparing with the Ii equation which is appropriate here we find that

Next what we find is

Thus from the given information we find that

Answer:
h(r) = 6(r+1)+10
Step-by-step explanation:
Just solve for q. Because that's the output. h(r) = q
Answer:
$38.57
Step-by-step explanation:
Make a proportion.

Cross multiply.
27 times 100 = 2700
2700 divided by 70 = 38.57142857
Round the result to the hundredths place.
38.57142857 ≈ 38.57
**Hope this helps!
Answer:
q =90
Step-by-step explanation:
q/18=5
Multiply each side by 18
q/18 * 18=5* 18
q =90
So assuming that 25cm is 25 square cm because you cannot have a 2 dimentional cake so
600mm by 500mm
to find the area, multiply legnth by width
mm=milimeters
cm=centimeters
this is in mm so
1cm=10mm
1mm=1/10cm
to convert from mm to cm, you divide by 10
we must divide by 10 first
legnth =600mm
600/10=60cm
legnth=60cm
width=500mm
500/10=50cm
width=50cm
area=60 times 50=3000 square cm or cm^2
so 3000 is the area
25 is the area of each cake
divide 3000 into 25 and find how many cakes will fit
3000/25=120
120 cakes will fit
