Answer:

Step-by-step explanation:

Hi,
<span>SP=Selling Price
</span>CP of dress= $ 89.47
percent of mark up = 50%
SP without tax= 100+ mark up % /100 * CP
<span>SP without tax= 100+50/100 * 89.47
</span>SP without tax= 150/100 * 89.47
SP without tax= 1.5 * 89.47
<span>SP without tax= $ 134.205
</span>tot. SP(SP with tax)= 100 + tax %/100 * SP
<span>SP=100 + 7.6/100 * 134.205
</span>SP= 107.6/100 * 134.205
SP= 1.076 * 134.205
<span>SP= $144.40458
Hope this helps you.</span>
Answer:
P( That it will take over 10 years or more of a year with a rainfall above 50inches) = (0.9938)^10
Step-by-step explanation:
Since the annual rainfall is normally distributed,
Given: that
Mean (µ )= 40
and σ = 4.
Let X be normal random variables of the annual rainfall.
P(that there will be over 10 years or more before a year with a rainfall above 50 inches)
P(>50) = 1-P[X ≤50]
1 - P[X- μ/σ ≤ 50 - 40/4]
=1 - P [Z≤ 5/2]
=1 -Φ(5/2)
=1 - 0.9939
= 0.0062
P( the non occurrence of rainfall above 50 inches)
= 1-0.0062
=0.9938
ASSUMPTION:
P( That it will take over 10 years or more of a year with a rainfall above 50inches) =
