Considering the definition of probability, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].
Definition of probabilityProbability is the greater or lesser chance that a given event will occur.
In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases.
[tex]P(A)=\frac{number of favorable events}{ total number of possible events}[/tex]
The probability of event A can only be a number between 0 and 1; although it can also be written as a percentage.
Probability that the next customer pay with a debit cardIn this case, you know:
Total number of customers = 57 +12 +70= 139 (total number of possible cases)The number of customers that used a debit card = 12 (number of favorable cases)Replacing in the definition of probability:
[tex]P(A)=\frac{12}{ 139}[/tex]
Finally, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

What is the value of x?
Enter your answer in the box.
Answer:
x = 25
Step-by-step explanation:
Use Pythagoras' Theorem [tex]a^s+b^2=c^2[/tex]
where a and b are the legs and c is the hypotenuse of a right triangle
[tex]\implies 7^2+24^2=x^2[/tex]
[tex]\implies 49+576=x^2[/tex]
[tex]\implies 625=x^2[/tex]
[tex]\implies x=\sqrt{625}[/tex]
[tex]\implies x=\pm25[/tex]
[tex]\implies x = 25[/tex] only, as distance is positive
Use Pythagorean theorem
[tex]\\ \rm\longmapsto x^2=24^2+7^2[/tex]
[tex]\\ \rm\longmapsto x^2=576+49[/tex]
[tex]\\ \rm\longmapsto x^2=625[/tex]

Rachel is going to rent a truck for one day. There are two companies she can choose from, and they have the following
prices,
Company A charges $79 and allows unlimited mileage.
Company B has an initial fee of S65 and charges an additional S0.70 for every mile driven
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer:
65 + .70(20)= 79 dollars
Step-by-step explanation:
65+0.70miles = Fee
this means she can drive 19 miles and she will still be below the price company A but as soon as she drives 20 miles company A and B will cost the same

Find the area of the circle to the nearest whole number, if necessary!
Answer:
The circle has an area of about 1385 square mm.
Step-by-step explanation:
Let's recall that circles have an area that can be found with the following formula:
[tex]A=\pi r^{2}[/tex]
where r is the radius of the circle.
Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.
[tex]A=\pi (21)^2\\A=441\pi \\A=1385.44236...[/tex]
So, to the nearest whole number, the area of the circle is 1385 square mm.

The circumference of Circle K is pi. The circumference of Circle L is 4xpi.
Two circles, one labeled “Circle K” and the other as “Circle L.”
What is the value of the ratio of their circumferences? of their radii? of their areas? Write the ratios as fractions in the simplest form.
Answer:
Ratio of circumferences: [tex]\displaystyle\frac{1}{4}[/tex]
Ratio of radii: [tex]\displaystyle\frac{1}{4}[/tex]
Ratio of areas: [tex]\displaystyle\frac{1}{16}[/tex]
Step-by-step explanation:
Hi there!
We are given:
- The circumference of Circle K is [tex]\pi[/tex]
- The circumference of Circle L is [tex]4\pi[/tex]
Therefore, the ratio of their circumferences would be:
[tex]\displaystyle\frac{\pi}{4\pi}[/tex] ⇒ [tex]\displaystyle\frac{1}{4}[/tex] when simplified
The formula for circumference is [tex]C=2\pi r[/tex], where r is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.
If the circumference of Circle K is [tex]\pi[/tex], or [tex]1\pi[/tex], then its radius is [tex]\displaystyle\frac{1}{2}[/tex].
If the circumference of Circle L is [tex]4\pi[/tex], then its radius is [tex]\displaystyle\frac{4}{2}[/tex], which is 2.
Therefore the ratio their radii would be:
[tex]\displaystyle\frac{\frac{1}{2}}{{2}}[/tex] ⇒ [tex]\displaystyle\frac{1}{2}*\frac{1}{2}[/tex] ⇒ [tex]\displaystyle\frac{1}{4}[/tex] when simplified
The formula for area is:
[tex]A=\pi r^2[/tex]
First, let's find the area of Circle K:
[tex]A=\pi (\displaystyle\frac{1}{2})^2\\\\A=\displaystyle\frac{1}{4}\pi[/tex]
Now, let's find the area of Circle L:
[tex]A=\pi (2)^2\\A = 4\pi[/tex]
Therefore, the ratio of their areas would be:
[tex]\displaystyle\frac{\frac{1}{4}\pi}{4\pi}[/tex] ⇒ [tex]\displaystyle\frac{\frac{1}{4}}{4}[/tex] ⇒ [tex]\displaystyle\frac{1}{4} * \frac{1}{4}[/tex] ⇒ [tex]\displaystyle\frac{1}{16}[/tex] when simplified

Paisley and Damian are both driving along the same highway in two different cars to
a stadium in a distant city. At noon, Paisley is 315 miles away from the stadium and
Damian is 383 miles away from the stadium. Paisley is driving along the highway at a
speed of 42 miles per hour and Damian is driving at speed of 59 miles per hour. Let
P represent Paisley's distance, in miles, away from the stadium t hours after noon.
Let D represent Damian's distance, in miles, away from the stadium t hours after
noon. Write an equation for each situation, in terms oft, and determine whether
Paisley or Damian is closer to the stadium 5 hours after noon.
are
Using linear functions, it is found that:
Paisley's equation is: P(t) = 315 - 42t.Damian's equation is: D(t) = 383 - 59t.Damian is closer to the stadium 5 hours after noon.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 also be interpreted as the initial value.Paisley is 315 miles away from the stadium, and driving at a speed of 42 miles per hour, hence for the linear equation for his distance after t hours, we have that:
m = -42, b = 315, then:
P(t) = 315 - 42t.
Damian is 383 miles away from the stadium, and driving at a speed of 59 miles per hour, hence for the linear equation for his distance after t hours, we have that:
m = -59, b = 383, then:
D(t) = 383 - 59t.
After 5 hours, their distances are:
P(5) = 315 - 42(5) = 105
D(5) = 383 - 59(5) = 88
D(5) < P(G), hence Damian is closer to the stadium 5 hours after noon.

area (a)=l×b
70=l×7
70=7l
70÷7=l
10=l
therefore, itslength is 10m
again,
perimeter (p)=2(l+b)

Graph the quadrilateral with the given vertices in the coordinate plane.
A(0, 1), B(4, 4), C(12, 4), D(8, 1)
Answer:
Because BC=AD=8, segment BC ≅ Segment AD. Because these are horizontal line segments, their slopes are 0 and they are parallel.
Segment BC and AD are opposite sides that are both congruent and parallel. So ABCD is a parallelogram by the opposite sides congruent theorem.
Step-by-step explanation:
So if you count the boxes of segment BC you will get 8, same for if you count the boxes that make up segment AD. If they are the same distance they are congruent. You can see how BC and AD are both horizontal lines. To find the slope you need to do the slope formula for BC and AD, which is y2-y1/x2-x1 in our case BC= 4-4/12-4 which equals 0/8. If you do the same formula for AD, you will get 0/8 making them congruent and the slope 0. If the opposite sides are congruent and parallel it has to be a parallelogram by the opposites and congruent theorem.

David throws a bucket with an initial speed of 2 meters per second into a well that is 30 meters deep. When will the bucket hit the bottom of the well?
A. About 2.69 seconds
B. About 30 seconds
C. About 3.82 seconds
D. About 4.21 seconds
Answer: A
Applying the expression for speed, we found that the time taken for the bucket to hit the bottom of the well is 15 seconds
Speed, Distance, TimeGiven Data
Speed = 2 meters per second
Distance = 30 meters
Time = ??
We know that the expression for the relationship between speed, distance and time is given as
Speed = Distance/Time
substituting we have
2 = 30/t
cross multiplying
2t = 30
divide both sides by 2
t = 30/2
t = 15 seconds
