Answer:

False Option B

Step-by-step explanation:

From the question we are told that:

Sample size n=10

Assumed degrees of freedom df'=19

Generally for the df of the t test

If Cp = Rs 660, Loss percent = 5% find Sp​
Aneli [31]

Answer:

SP = 627 Rs

Step-by-step explanation:

Percentage loss is calculated as

\frac{CP-SP}{CP} , then

\frac{660-SP}{660} = 5% = 0.05 ( multiply both sides by 660 )

660 - SP = 33 ( subtract 660 from both sides )

- SP = - 627 ( multiply both sides by - 1 )

SP = 627 Rs

400 pounds per 340 square feet” as a rate in simplest form
Airida [17]
400lbs/340ft^2

Factor out largest common factor.  LCF is the product of shared primes of the numbers prime factorization.

400=2*2*2*2*5*5,  340=2*2*5*17

So the product of the shared primes is 2*2*5=20, so divide the numerator and denominator by 40.

(400/20)lbs/(340/20)ft^2

20lbs/17ft^2  or if you prefer

(20/17)lbs/ft^2

(1 3/17)lbs/ft^2 or approximately

1.18 lbs/ft^2
