1 answer:

3 0

We know that
the number of coins that each roll contains is
rolls of quarters-------> 40 coins
rolls of Dimes---------> 50 coins
rolls of nickels------> 40 coins

four rolls of quarters------> 4*40*$0.25-----> $40
three rolls of Dimes-----> 3*50*$0.10------> $15
six rolls of nickels-------> 6*40*$0.05-----> $12

total=[40+15+12]------> $67

the answer is
$67

BigorU [14]

Answer:

Step-by-step explanation:

Alice borrowed 16700 from the bank at a simple interest rate of 9% to purchase a used car. It means that the interest is not compounded. Simple interest is usually expressed per annum. The formula for simple is

I = PRT/100

Where

I = interest

P = principal(amount borrowed from the bank)

R = 9% ( rate at which the interest is charged

T = number of years

At the end of the loan,she had paid a total of 24215. This means that the interest + the principal = 24215

Therefore,

The interest = 24215 - 16700 = 7515

Therefore

7517 = (16700 × 9 × t)/100

751700 = 150300t

T = 751700/150300

T = 5 years

Converting 5 years to months,

1 year 12 months

5 months = 12 × 5 = 60 months

Suppose an electronics manufacturer takes a sample of 5000 devices produced by an assembly line. Each device is inspected or tes

Deffense [45]

Answer:

DPMO = 40

Does not meet Six Sigma goals

Step-by-step explanation:

If there are 40 possible defects in each of the 5,000 devices, the number of defect opportunities is:

$n=5,000*40\\n=200,000\ opportunities$

If 8 total defects were found, the DPMO for the sample is:

$DPMO = \frac{8}{200,000}*1,000,000\\DPMO = 40$

Six Sigma aims to reduce defects to 3.4 Defects Per Million Opportunities, since the DPMO is higher than 3.4, the process does not meet Six Sigma goals.

Answer:

-35.626 < temperature < 733.928 . . . . degrees F

(-35.626, 733.928)

Step-by-step explanation:

It is convenient to let a calculator evaluate the expression for converting °C to °F.

-35.626 < temperature < 733.928 . . . . degrees F

(-35.626, 733.928) . . . . . . . . . . . . . . . . . in interval notation
