Cost of four DVD= 36.7, but due to 25% discount it cost 27.57. Then add 7.75 taxes and he payed 29.71. Answer is 29.71
Step-by-step explanation:
Answer:
$27.71
Step-by-step explanation:
Price of 1 DVD: $9.19
Price of 4 DVDs: 4 * $9.19 = $36.76
Discount: 25%
Now we find 25% of $36.76.
25% of $36.76 =
= 0.25 * $36.76
= $9.19
The 25% discount amounts to $9.19. We now subtract $9.19 from $36.76 to find the discounted price.
$36.76 - $9.19 = $27.57
Now we need to apply the 7.75% tax to $27.57.
7.75% of $27.57 =
= 0.0775 * $27.57
= $2.14
The sales tax is $2.14.
Now we add the sales tax amount to the total discounted price.
$27.57 + $2.14 = $29.71
Answer: $27.71
The number of typing errors made by a typist has a Poisson distribution with an average of five errors per page. If more than five errors appear on a given page, the typist must retype the whole page. What is the probability that a randomly selected page does not need to be retyped
Answer:
0.61596
Step-by-step explanation:
Given that:
λ = 5 (5 errors per page)
Poisson distribution formula :
P(x = x) = (λ^x * e^-λ) / x!
Probability that page does not need to be retyped means that error on page is less than or equal to 5
P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)
The individual probabilities can be obtained using the formula above or the use of a calculator
P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674
P(x ≤ 5) = 0.61596

A living room wall is 13 feet long. How far from the corner would you have to the edge of a 3ft 6in shelf for it to be centered on the wall?
Answer:
You start the shelf 4 ft. 9 in. from the wall.
Step-by-step explanation:
The game plan is to take the length of the shelf away from the length of the wall, and then divide the remaining part into two equal pieces.
13 ft.
- 3 ft. 6 in.
12 ft 12 in,
- 3ft 6 in
9 ft 6 in.
9 ft. 6 inches divided by 2 equals 4.5 ft, 3 in.
.5 ft * 12 inches = 6 inches
You start the shelf 4 ft. 9 in. from the wall.
The length from the corner for the edge of a 3ft 6in shelf for it to be centered on the wall is A = 4.75 feet = 4 feet 9 inches
What is the diagonal of a rectangle?The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
To center a shelf on a 13-foot long wall, we need to find the midpoint of the wall, and then subtract half the length of the shelf to determine the position of the shelf's edge.
First, we need to convert 3 feet 6 inches to feet. There are 12 inches in a foot, so:
3 feet 6 inches = 3 + 6/12 = 3.5 feet
Now , the diagonal of the rectangular shelf is
The midpoint of the wall is half of 13 feet, which is:
13 / 2 = 6.5 feet
To find the distance from the corner to the edge of the shelf, we need to subtract half the length of the shelf from the midpoint of the wall:
6.5 feet - 1.75 feet = 4.75 feet
Hence , the shelf should be placed 4.75 feet from the corner to be centered on the 13-foot long wall.

Answer:
1213 tablespoons
1 teaspoon
Step-by-step explanation:
This answer is my interpretation of what the question is asking, it could be wrong.
This question says, one has 2426 tablespoons, and 2 teaspoons of a substance. If one were divided that quantity in half, how much of that substance could they have. So essentially, all one needs to do is divided 2426 by 2, and divide 2 by 2.
2426 ÷ 2 = 1213
2 ÷ 2 = 1
