The probability that the next customer will pay with a debit card or a credit card is 12%.
What is the probability that the next customer would pay with a debit card or a credit card?
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the next customer would pay with a debit card or a credit card = (number of customers that paid with a debit card + number of customers that paid with a credit card) / total number of customers
(8 + 2)/ 83 = 0.12 = 12%

A chocolatier makes chocolate covered cherries in the form of spheres. Amelia
measures the outer diameter of these chocolates to be 2.8 cm. If she measures the
thickness of the chocolate to be 0.5 cm, how much chocolate is used in one of the
chocolate covered cherries? Round your answer to the nearest hundredth if
necessary. (Note: diagram is not drawn to scale.)
The volume of the chocolate is the amount of choclate used in the cherries
The amount of chocolate used is 17.24 cubic centimeters
How to determine the amoumt of chocolate?Start by calculating the volume of the cherries using:
V = 4/3 π(D/2)^3
The diameter of the cherry is 2.8 cm.
So, we have:
V = 4/3π(2.8/2)^3
Evaluate
V = 11.49
Next, calculate the volume of the cherry and the chocolate.
V = 4/3π(0.5+2.8/2)^3
V = 28.73
Calculate the difference (d) between both volumes
d = 28.73 - 11.49
d = 17.24
Hence, the amount of chocolate used is 17.24 cubic centimeters

A string of a kite is 100 meters long and the inclination of the string with the ground is 60°. Find the height of the kite, assuming that there is no slack in the string.
Answer:
86.5
Step-by-step explanation:
Length of the string forms the hypotenuse AC of right angle triangle ABC.
C is the kite. A is the hand of the person (or, one end of the string). CB is the perpendicular
(height of the kite) from C on the ground. BC is the horizontal.
Sin 60° CB/AC = √3/2
height = 1.73/2 AC = 0.865 * 100 m = 86.5 m

3. Avery records her rock-climbing progress and finds that her altitude, in kilometers above sea
level, can be represented by a linear model, A = 7+ 1.3t, where t is the number of hours since
Avery started climbing.
Based on this model, how many kilometers above sea level was Avery's altitude before she started
climbing?
km
Using the given linear function, it is found that Avery was 7 kilometers above sea level before she started climbing.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can be interpreted as the initial value.In this problem, her altitude in kilometers after t hours is modeled by:
A(t) = 7 + 1.3t.
The y-intercept is of b = 7, which means that Avery was 7 kilometers above sea level before she started climbing.

The difference between the number of items on two grocery lists is 7. The combined total number of items on the lists is 33.
Answer:
20 and 13
Step-by-step explanation:
If one list is 'a' and the other one is 'b' then
a-b = 7 and a+b = 33
a-b+a+b = 7+33
2a = 40
a = 20
Now, 20 - b = 7
-b = -13
b = 13

YAY!!!!!!!
The fraction of the exams that Mr Tough and Mrs Nice grade in 1 hour if they work together is 3/20
What are fractions?In Maths, a fraction is used to represent the portion/part of the whole thing. A fraction has two parts, namely numerator and denominator. There are proper fractions, improper fractions and mixed fractions.
Example: 2/5, 1/4 etc.
How to solve Work and Time problems:We will this equation,
rate × time = work done
For this problem:
Mr Tough's rate:
Mr Tough's rate × 12 hours = final exam
Mr Tough's rate = 1/12
Mrs.Nice's' rate:
Mrs .Nice's' rate × 15 hours = final exam
Mrs .Nice's' rate = 1/15
To make this into a solvable equation, find the total time (T) needed for Mr Tough and Mrs.Nice to grade the final exam. This time is the sum of the rates of Mr Tough and Mrs.Nicea, or:
Total time:
T(1/12 hours + 1/15 hours) = final exam
T = final exam / (1/12 + 1/15)
Simplifying we get,
T = final exam / (0.15)
Now, to finish in 1 hour we will find what fraction of the final exam they can grade, so taking T = 1 hour,
1 hour = final exam / (0.15)
By further simplifying,
final exam = 1 × 0.15
= 0.15
= 15/ 100
= 3/20
Therefore, 3/20 fraction of the final exam they can grade if they work together for 1 hour.
