The probability of rolling a 4 on a number cube and pulling a red marble out of the bag is 1/20.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
The probability of rolling a 4 on a number cube is 1/6, since there is one way to roll a 4 out of six possible outcomes (1, 2, 3, 4, 5, 6).
The probability of pulling a red marble out of the bag is 3/10, since there are three red marbles out of a total of ten marbles.
To find the probability of both events happening (rolling a 4 and pulling a red marble), we multiply the probabilities:
(1/6) x (3/10) = 1/20
Therefore, the probability of rolling a 4 on a number cube and pulling a red marble out of the bag is 1/20.

Concept:
What are Inverse trigonometric functions?
Inverse trigonometric functions are represented as arcsinx, arccosx, arcsecx, and so on.
The trigonometric functions that are used to calculate an angle from any of the angle's trigonometric ratios are called inverse functions.
The formula which is used to in inverse trigonometric equations are:
arcsinx = -arcsinx
arccosx = pi-arccosx
arctanx = -arctanx
arcsecx = pi - arcsecx
Solution:
The maximum values we obtain from the following equations are:
arcsinx = -1 to 1
arccosx = -1 to 1
arctanx = -pi/2 to pi/2
arcsecx = ∞
So the trigonometric functions which have the same maximum value is arcsinx and arccosx.

Points J, K, and L are collinear one, and JL: LK = J is located at (-3,5), K is located at (1,-10) and Lis located at (x, y). What are the values of x and y?
9514 1404 393
Answer:
L = (x, y) = (1/5, -7)
Step-by-step explanation:
The given relation tells you ...
(L -J)/(K -L) = 4/1
Cross-multiplying, we have ...
L -J = 4(K -L)
5L = 4K +J . . . . add 4L+J
L = (4K +J)/5
L = (4(1, -10) +(-3, 5))/5 = (4-3, -40+5)/5
L = (x, y) = (1/5, -7)

A reflection across the x-axis maps the point (4,-5) to the point
Answer:
(4,5)
Step-by-step explanation:
A reflection is a mirror image of the shape.
A reflection across the x-axis maps point (4,-5) to point (4. 5).
What is reflection?A reflection is a mirror image of the shape.
After the reflection, every point in a figure is equidistant from each corresponding point in the reflected figure.
We have,
A point = (4, -5)
The point is reflected across the x-axis.
The reflection formula is given as:
Reflection across the x-axis:
(x, y) → (x, -y)
Reflection across the y-axis:
(x, y) → (-x, y)
The point (4, -5) reflected across the x-axis is:
(4, -5) → (4, - (-5)) = (4, 5)
Thus,
A reflection across the x-axis maps point (4,-5) to point (4. 5).

In 1902, the yearly attendance at a major league baseball park was 3.4 × 105 people.
One hundred years later, the yearly attendance was 1.7 × 106 fans.
How many times greater was the attendance in 2002 than in 1902? Enter your answer in the box.
Answer:
The number of attendance is 5 times greater than in 1902.
Step-by-step explanation:
Since we have given that
Number of attendance at a major league baseball park in 1902 =
Number of attendance at a major league baseball park in 2002 =
We need to find the number of times that the attendance in 2002 is greater than in 1902.
So, number of times becomes,
Hence, the number of attendance is 5 times greater than in 1902.
Suppose that you borrow $11000 for 4 years at 6% toward the purchase of a car. Find the monthly payments and the total interest for the loan.
Answer:
The monthly payments ≅ $258.335
The total interest of the loan ≅ $1400.095
Step-by-step explanation:
The rule of the monthly payments is
[tex]M.P=\frac{P(\frac{r}{n})}{1-(1+\frac{r}{n})^{-nt}}[/tex] , where
P is the initial amountr is the rate in decimaln is the period in a yeart is the number of years∵ You borrow $11000
∴ P = 11000
∵ It will be for 4 years
∴ t = 4
∵ The rate is 6%
∴ r = 6% = [tex]\frac{6}{100}[/tex] = 0.06
∵ It is a monthly payment
∴ n = 12
→ Substitute these values in the rule above
∴ [tex]M.P=\frac{11000(\frac{0.06}{12})}{1-(1+\frac{0.06}{12})^{-12(4)}}[/tex]
→ Use your calculator to find the answer
∴ M.P = 258.3353195
∴ The monthly payments ≅ $258.335
→ The total interest of the loan is the difference between the total
of the monthly payments and the initial amount
∴ The total interest of the loan = T.M.P - P
∵ The total of the monthly payments = M.P × t × n
∴ The total of the monthly payments = 258.3353195 × 4 × 12
∴ The total of the monthly payments = $12400.09534
∵ The initial amount P = $11000
∴ The total interest of the loan = 12400.09534 - 11000
∴ The total interest of the loan = 1400.095
∴ The total interest of the loan ≅ $1400.095

Answer:
x= 8
z= 116 degrees
Step-by-step explanation:
the two given angle measures are vertical angles so they are equal to each other, the equation is: 12x-32 = 11x-24
simplify this to get: x= 8
plug the value of x into either of the given equations, I will use the first one: 12(8) - 32
this means that the angle of one of them is 64
and since z and 12x-32 make a straight angle (180 degrees)
you can subtract 64 from 180 to find z
this gives you 180-64 = 116
9.The Bridgeport water department has a monthly service charge of $12.60 and a volume charge of
$1.38 for every 100 cubic feet of water. Write an equation that can be used to determine the Morgan
family's monthly water bill.
[tex]y = 1.38x + 12.60[/tex]
Step-by-step explanation:
the 12.60 is going to be charged every months no matter what it's fixed so that's why it's added! the 1.38 is a rate, so how many cubic inches she uses in increments of 100 she will be charged so that depends on how much she uses in addition to that 12.60for example she uses 700 cubic feet of water once month well (x) will be 7 because u divide it by 100 and it'll give u ur "x". put it into the formula and it'll give the price she'll have to pay. 1.38(7) + 12.60 and this will equal $21.70 !Which of the following should come next at the end of this row of letters?
