Answer:
let cp be x
sp= 115x/100 ---(when 15%gain)
sp = 88x/100------(when 12% loss
according to question
115x/100 - 88x/100 = 81
or, (115x-88x)= 8100
or, 27x = 8100
or, x= 8100/27
x = 300
hence cp is RS 300
Answer:
the values of the population and sample proportions is 0.64 and 0.6 respectively
Step-by-step explanation:
The computation of the values of the sample proportions and the population is shown below:
Given that
Let us assume the population be P
N= 1000
X = subjects possess specific characteristic = 640
So,
P = X ÷ N
= 640 ÷ 1000
= 0.64
And, the sample proportion is
n = 40
x = subjects possess specific characteristic = 24
p =X ÷ N
= 24 ÷ 40
= 0.6
hence, the values of the population and sample proportions is 0.64 and 0.6 respectively
Hi there! The answer is $465
The total cost can be found using the formula

To find the amount of money Ben Frank charges, we need to plug in the data from the question.
h = number of hours worked = 7
f = number of fixtures installed = 9

Therefore, Ben Frank charges $465

Answer:
see explanation
Step-by-step explanation:
Let ∠4 be x then ∠6 is
x
∠4 and ∠6 are same side interior angles and are supplementary, thus
x +
x = 180
Multiply through by 8 to clear the fraction
8x + x = 1440, that is
9x = 1440 ( divide both sides by 9 )
x = 160
Hence ∠4 = 160° and ∠6 = 160° ÷ 8 = 20°
