Answer:
1.328
Step-by-step explanation:
Given :
Sample size, n = 20.
Degree of freedom, df = n - 1
df = 20 - 1 = 19
α = 0.2
Using the T-distribution calculator :
Since it is two - tailed:
Tα/2 ; 19 = T0.2/2 ; 19 = T0.1, 19 = 1.3277 = 1.328
Answer:
Option C
23.08% markup on selling price.
Step-by-step explanation:
Given in the question,
markup percentage on cost price = 30%
To find,
markup percentage on selling price
Markup is the ratio between the cost of a good or service and its selling price.
Let suppose that cost price percentage = 100%
As we know that,
<h3>cost% + markup% = selling%</h3><h3>100% + 30% = 130%</h3>
So percent markup selling price = 30 / 130 x 100
= 23.0769
Hence, 30% markup on cost price = 23.0769% markup on selling price.
Hello :
let : z = 4-3ii z' = -2+7i
the distance between the points 4-3i and -2+7i is : <span>|z - z' |
</span> |z - z' | = |4-3i+2-7i| = |6-10i | =√(6²+(-10)²) =√136
