A shop sells floor tiles at Rs 48 per square meter. A

Alekssandra [29.7K]

Answer:

c. 528000

Step-by-step explanation:

The computation of the amount that need to be paid is shown below:

Let us assume the side of the square shaped hall be X meter s

So,

Perimeter = 4X

Now

4X = 400

X = 100m

Now

Area of the hall = 100 × 100 = 10000 sq. meter.

And,

The cost on total tiles is

= 10,000 × 48 = Rs. 480000

But, there is 10% damage has occurred that involved in the cost

So,

Total cost is

= Rs 480,000 + 10% of 480,000

= 480,000 + 48,000

= Rs. 5,28,000

In a large sample of customer accounts, a utility company determined that the average number of days between when a bill was sen

vaieri [72.5K]

Answer:

Approximately 95% of the numbers of days will be between 26 and 58.

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 42

Standard Deviation, σ = 8

We are given that the distribution of average number of days between a bill is a bell shaped distribution that is a normal distribution.

Empirical Formula:

According to Empirical formula almost all the data lies within three standard deviation of man for a normal distribution.
Almost 68% of data lies within 1 standard deviation of mean.
Almost 95% of data lies within two standard deviation of mean.
Almost 99.7% of data lies within three standard deviation of mean.

Thus, by Empirical formula 95% of data lies within two standard deviation.

$\mu \pm 2(\sigma) \\=42 \pm 2(8)\\=42 \pm 16\\=(26, 58)$

Thus, approximately 95% of the numbers of days will be between 26 and 58.

Two methods, A and B, are available for teaching a certain industrial skill. The failure rate is 15% for A and 5% for B. However

baherus [9]

Answer:

P(A | F) = 81.81%

There is 81.81% probability that worker was taught by method A given that he failed to learn it correctly.

Step-by-step explanation:

The failure rate is 15% for A which means that

P(F | A) = 0.15

The failure rate is 5% for B which means that

P(F | B) = 0.05

Method B is more expensive and hence is used only 40% of the time which means that

P(B) = 0.40

Which means that A is used the other 60% of the time

P(A) = 0.60

A worker is taught the skill by one of the methods but fails to learn it correctly.

We are asked to find the the probability that he was taught by method A.

So that means we want to find out

P(A | F) = ?

We know that according to Baye's rule,

$P(A \:|\: F) = \frac{P(F \:|\: A)\times P(A) }{P(F \:|\: A)\times P(A) + P(F \:|\: B)\times P(B) }$

Substitute the given probabilities into the above equation

$P(A \:|\: F) = \frac{0.15\times 0.60 }{0.15\times 0.60 + 0.05\times 0.40}\\\\P(A \:|\: F) = \frac{0.09 }{0.09 + 0.02}\\\\P(A \:|\: F) = 0.8181 \\\\P(A \:|\: F) = 81.81\%$

Therefore, there is 81.81% probability that worker was taught by method A given that he failed to learn it correctly.
