Answer:
62.5 %
Step-by-step explanation:
32 - 12 = 20 ounces left
20/32 = 0.625
0.625 x 100 = 62.5 %
Best Answer: Bill's time to do the whole job, B
Jeff's time, B + 5
time they actually work, 6.
6/B + 6/(B+5) = 1
6(B+5) + 6B = B(B+5)
6B + 30 + 6B = B² + 5B
B² - 7B - 30 = 0
(B - 10)(B + 3) = 0
B = 10 or B = -3, and we reject the negative solution.
the equation is based on adding the fractions of the whole job each does. if Bill takes B hours to do the whole thing and works 6, he does 6/B of the job. similarly for Jeff.
in the 2nd problem,
a = time of experienced accountant
2a = time of new accountant
10 = time each actually works
10/a + 10/(2a) = 1 ........ multiply all by a
10 + 5 = a
a = 15 hr.
Answer:
2p − 1
Step-by-step explanation:
I think, sry is its wrong. Do you have possible answrs?
-4p - (1 - 6p) = -4p - 1 + 6p = -4p + 6p - 1 = 2p - 1
Answer:
a) 25
b) 49
c) 97
Step-by-step explanation:
The sample size is calculated using the formula, n = 
Now,
for 95% confidence level value of z-factor = 1.96
Given:
Mean = $3.94
standard deviation = $0.25
thus,
a) for margin of error = $0.10
n =
or
n = 
or
n = 4.9²
or
n = 24.01 ≈ 25 (Rounded off to next integer)
b) for margin of error = $0.07
n =
or
n = 
or
n = 7²
or
n = 49
c) for margin of error = $0.05
n =
or
n = 
or
n = 9.8²
or
n = 96.04 ≈ 97 (Rounded off to next integer)
