the cost of day old donuts after the discount is $4.95.
what is discount?A discount is a decrease in the cost of a good or service. Discount is the reduction in the price of goods or services offered by shopkeepers at the marked price.
Discounts are offers or rebates made to customers on the marked-down prices of goods. We come across phrases like cost price, tagged price, discount, and selling price when making a purchase. Shop owners give discounts to customers to encourage product sales. Let's examine the connections between these concepts.
The formula to calculate the discount is:
Discount = List Price - Selling Price
Discount (%) = (Discount/List Price) × 100
the discount is 40% ⇒0.4
customer buys 3 donuts.
price of 1 donut = $2.75
total cost for 3 donuts= $2.75 x 3 = $8.25
discount for 1 donut= [tex]\frac{0.4}{100}* 2.75[/tex]=$1.1
so, for 3 donuts discount = $1.1 x 3 = $3.3
therefore the final price to be paid by customer is
=$8.25-$3.3
=$4.95

An engine does 62 J of work each cycle as it absorbs 2 times as much heat as it discharges to the environment. A) Determine the efficiency of the engine in percent. B) What quantity of heat is discharged to the environment each cycle in Joules?
Answer:
A) 150%
B) 20.67 J
Step-by-step explanation:
A) To determine the efficiency of the engine, we can use the formula:
efficiency = (work output / heat input) x 100%
In this case, the engine does 62 J of work each cycle, so the work output is 62 J. We're also given that the engine absorbs 2 times as much heat as it discharges to the environment, so we can express the heat input as 2 times the heat discharged:
heat input = 2 x heat discharged
Therefore, we can rewrite the efficiency formula as:
efficiency = (62 J / (2 x heat discharged)) x 100%
Simplifying this expression, we get:
efficiency = 31 J / heat discharged
Now we need to determine the value of heat discharged. We know that the engine absorbs 2 times as much heat as it discharges, so the net heat input is 3 times the heat discharged:
net heat input = heat input - heat discharged = 2 x heat discharged - heat discharged = heat discharged
Therefore, we can express the net heat input as:
net heat input = 3 x heat discharged
Now we can use the first law of thermodynamics, which states that the net heat input is equal to the work output plus the heat discharged:
net heat input = work output + heat discharged
Substituting the given values, we get:
3 x heat discharged = 62 J + heat discharged
Solving for heat discharged, we get:
heat discharged = 20.67 J
Now we can calculate the efficiency:
efficiency = 31 J / 20.67 J = 1.50 or 150%
Therefore, the efficiency of the engine is 150%.
B) To determine the quantity of heat discharged to the environment each cycle in Joules, we can use the value we calculated above for heat discharged:
heat discharged = 20.67 J
Therefore, the quantity of heat discharged to the environment each cycle is 20.67 J.

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where:
P(X = k) is the probability of getting k successes
n is the number of trials
p is the probability of success on one trial
(n choose k) is the binomial coefficient, which is equal to n! / (k! * (n - k)!)
k is the number of successes we want to find the probability for
Using this formula, we can find the probabilities for the given scenarios:
a. P(X = 4) = (10 choose 4) * 0.15^4 * (1 - 0.15)^(10 - 4) = 0.1611
b. P(X <= 1)
= P(X = 0) + P(X = 1)

c. P(X >= 1)
= 1 - P(X = 0)
= 1 - (10 choose 0) * 0.15^0 * (1 - 0.15)^(10 - 0)
= 0.7588
d. P(X > 1)
= 1 - P(X <= 1)
= 1 - (P(X = 0) + P(X = 1))
= 1 - ((10 choose 0) * 0.15^0 * (1 - 0.15)^(10 - 0) + (10 choose 1) * 0.15^1 * (1 - 0.15)^(10 - 1))

What is distance ?Distance is an object's total, aimless movement. Without regard to whether an object represents a starting or finishing point, distance can be defined as the total distance travelled. Distance is referred to as the breadth or height of the difference between two locations. It should be highlighted that the distance between each of the vantage points as well as the distance travelled from one to the other are not the same thing. The total length of a path connecting two locations counts as the distance travelled. Distance is the real distance that a body travels. It also goes by the name "path length." For instance, the length of the route for an object moving from point O to point P would be OP = 360 m.
given,
To find the distance between the points (1, 5) and (3, 8), we can use the distance formula:
distance = √[(x2 - x1)² + (y2 - y1)²]
Substituting the given values, we get:
distance = √[(3 - 1)² + (8 - 5)²]
distance = √[4 + 9]
distance = √13

Generally, it is better to use a Line Graph if your raw data includes non-numeric values. If your raw data only has numeric values, use a Scatter Plot. You can use a Line Graph if you want to label your horizontal axis with text labels. These labels can represent evenly spaced values as days, weeks, and years.
