These are all equivalent to the ratio of 1:2
Step-by-step explanation:
Answer:
The correct answer is -7.5 years.
Step-by-step explanation:
Given:
Principle amount = 12000
Interest = 4320
time = ?
rate = 4.8 simple interest
Solution:
We know that simple Interest I = (P*t*r)/100
then t = I*100/p*r
putting values in formula:
t = 4320*100/4.8*12000
= 432000/57,600
= 7.5 years
Answer:
z=(x-mu)/o
Step-by-step explanation:
X - Heights of women aged 20 to 29: X is N(64, 2.7)
Y - Heights of men aged 20 to 29: X is N(69.3, 2.8)
a) X=6'=72"
b) Y = 72"
c) 72' women can be taken as very tall but men moderately taller than average
d) Y<5'5" =65"
e) X>73"
Z>
Almost 0% can be taken
f) IQR =Q3-Q1
They are vertical angles, thus they are equal to each other:
5x + 12 = 6x - 10
22 = x
x = 22
B = F / (S-C)
B - breaking point in units
F - fixed costs, S - selling price, C - cost per racket.
S-C is the profit on a single unit
B = 740000 / (77.59 - 39.72) = 19540.53
The breaking point is approached after selling 19541 units.
