Answer:
1/30
Step-by-step explanation:
All of the colours have the same probability of being spun. 5 colours.
So, P(spinning a green) = 1/5.
6-sided to a die.
So, P(rolling a 5) = 1/6
P(spinning a green AND rolling a 5) = (1/5) X (1/6) = 1/30
Please give the brainliest, really appreciated. Thank you
Answer:
1/30
Step-by-step explanation:
i got this answer because the probability of spinning green is 1/5, as there are 5 colors including green.
The probability of rolling 5 is 1/6, as there are 6 numbers including 5.
However, the questions asks for the probability of green and rolling 5, so I simply multiplied 1/6 and 1/5 and got 1/30.

A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses.
20,4,7,7, 10, 10
Find the median and mean number of hours for these students.
If necessary, round your answers to the nearest tenth.
(a) Median:
(b) Mean:
hours
hours
Answer: median = 8.5
mean=
9.7
total = 58
Answer:
median=8.5 hours Mean=9.7 hours
Step-by-step explanation:
First you take the values and add them together, find the sum.
20+4+7+7+10+10=x
x=58
now take 58 and divide it by the number of students
58/6=9.66666
the mean would be 9.7 hours since it asks to round to the nearest 10th
and for the median sort it from lowest to highest
4,7,7,10,10,20
now since in the middle are 7 and 10, add those together and divide by 2
10+7=17
17/2=8.5
the median is 8.5
Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negative 5 + x = negative 2
The equivalent equations that have the value x = 3 are:
2 + x = 5, x + 1 = 4, and (-5) + x = -2.
Equations are considered equivalent if they have the same solution(s). In other words, if you solve each equation for the variable, you should end up with the same value(s).
Let's look at the options given:
2 + x = 5: This equation can be solved by subtracting 2 from both sides, leaving x = 3.
x + 1 = 4: This equation can be solved by subtracting 1 from both sides, leaving x = 3.
9 + x = 6: This equation can be solved by subtracting 9 from both sides, leaving x = -3.
x + (-4) = 7: This equation can be solved by adding 4 to both sides, leaving x = 11.
-5 + x = -2: This equation can be solved by adding 5 to both sides, leaving x = 3.
So, we can see that the first, second, and fifth equations are equivalent since they all simplify to x = 3. The third and fourth equations are not equivalent to any of the other equations, since they have different solutions.

The x- and y-intercepts of the function g(x) = (x + 1)(x² − 10x + 24) include the following: A. x-intercepts: -1, 4, 6; y-intercept: 24.
What is the x-intercept?In Mathematics, the x-intercept is also referred to as horizontal intercept and the x-intercept of the graph of any function simply refers to the point at which the graph of a function crosses or touches the x-coordinate (x-axis) and the y-value or value of "y" is equal to zero (0).
When y = 0, the x-intercepts can be calculated as follows;
g(x) = (x + 1)(x² − 10x + 24)
0 = (x + 1)(x² − 10x + 24)
0 = (x + 1)(x² − 6x - 4x + 24)
0 = (x + 1)x(x − 6) -4(x - 4)
0 = (x + 1)(x - 6)(x - 4)
x = -1, 4, 6.
When x = 0, the y-intercept can be calculated as follows;
g(x) = (x + 1)(x² − 10x + 24)
g(0) = (0 + 1)(0² − 10(0) + 24)
g(0) = 24.

approximate the area under the curve y=x^3 from x=3 to x=6
To approximate the area under the curve y=x^3 from x=3 to x=6, we can use the midpoint rule with four subintervals.First, we need to find the width of each subinterval:delta x = (6 - 3) / 4 = 0.75Next, we can find the midpoint of each subinterval:x1 = 3 + 0.5 * delta x = 3.375
x2 = x1 + delta x = 4.125
x3 = x2 + delta x = 4.875
x4 = x3 + delta x = 5.625Now, we can evaluate the function at each midpoint:y1 = x1^3 = 40.39
y2 = x2^3 = 71.25
y3 = x3^3 = 106.29
y4 = x4^3 = 146.48Finally, we can use the midpoint rule formula to approximate the area:A ≈ delta x * (y1 + y2 + y3 + y4)
= 0.75 * (40.39 + 71.25 + 106.29 + 146.48)
= 267.98Therefore, the approximate area under the curve y=x^3 from x=3 to x=6 is 267.98 square units.

A small business owner is applying for a small business loan and has been approved for a $50,000 loan with 5.25% annual interest. The first loan is a simple interest rate, the second loan compounds interest quarterly, and the third loan compounds interest continuously. The small business owner plans to pay off the loan in 3 years and 8 months.
Part A: Determine the total value of the loan with the simple interest. Show all work and round your answer to the nearest hundredth.
Part B: Determine the total value of the loan with the quarterly compounded interest. Show all work and round your answer to the nearest hundredth.
Part C: Determine the total value of the loan with the continuously compounded interest. Show all work and round your answer to the nearest hundredth.
Part D: Using the values from Parts A, B, and C, explain which loan option is the best choice for the small business owner.
Part A: The total value of the loan with simple interest is $59,660.50.
Part B: The total value of the loan with quarterly compounded interest is $60,357.91.
Part C: The total value of the loan with continuously compounded interest is $60,441.82.
Part D: The best choice for the small business owner is the loan with simple interest, as it has the lowest total value and thus the lowest cost to repay.
Part A:
To calculate the total value of the loan with simple interest, we can use the formula:
[tex]Total value = Principal \times (1 + interest rate \times time)[/tex]
Where,
Principal = $50,000
Interest rate = 5.25% = 0.0525
Time = 3 years and 8 months = 3.67 years.
[tex]Total $ value = $50,000 \times (1 + 0.0525 \times 3.67) = $59,660.50[/tex]
Therefore, the total value of the loan with simple interest is $59,660.50.
Part B:
To calculate the total value of the loan with quarterly compounded interest, we can use the formula:
[tex]Total value = Principal \times (1 + (interest rate / n))^{(n \times time) }[/tex]
Where,
Principal = $50,000
Interest rate = 5.25% = 0.0525
Time = 3 years and 8 months = 3.67 years
n = 4 (since interest compounds quarterly)
[tex]Total value = $50,000 \times (1 + (0.0525 / 4))^{(4 \times3.67) } = $60,357.91[/tex]
Therefore, the total value of the loan with quarterly compounded interest is $60,357.91.
Part C:
To calculate the total value of the loan with continuously compounded interest, we can use the formula:
[tex]Total value = Principal \times e^{(interest rate \times time)}[/tex]
Where,
Principal = $50,000
Interest rate = 5.25% = 0.0525
Time = 3 years and 8 months = 3.67 years
[tex]Total value = $50,000 \times e^{(0.0525 \times 3.67) } = $60,441.82[/tex]
Therefore, the total value of the loan with continuously compounded interest is $60,441.82.
Part D:
From the calculations in Parts A, B, and C, we can see that the loan with continuously compounded interest has the highest total value of $60,441.82.
This is followed by the loan with quarterly compounded interest with a total value of $60,357.91, and finally the loan with simple interest with a total value of $59,660.50.
Therefore, the best choice for the small business owner would be to take the loan with simple interest, as it has the lowest total value and thus the lowest cost to repay.
However, if the small business owner is willing to pay a higher cost for the loan, they could consider the loan with quarterly or continuously compounded interest, which have higher total values.

what value of x is in the solution set of the inequality 2(3x-1)>4x-6
Answer: the solution set of the inequality 2(3x-1)>4x-6 is all values of x greater than -2.
Step-by-step explanation: To solve the inequality 2(3x-1)>4x-6, we first simplify the left side by distributing the 2, which gives us 6x-2. Substituting this back into the original inequality, we get:
6x-2 > 4x-6
Next, we isolate the variable term (6x) by subtracting 4x from both sides:
2x-2 > -6
Then, we add 2 to both sides to isolate the variable term completely:
2x > -4
Finally, we divide both sides by 2 to solve for x:
x > -2
Therefore, the solution set of the inequality 2(3x-1)>4x-6 is all values of x greater than -2.
The circle has center O. Its radius is 2 m, and the central angle a measures 160°. What is the area of the shaded region?
Give the exact answer in terms of
, and be sure to include the correct unit in your answer.
Answer:
Area_shaded_region = 2 * (√(1 - cos^2(4π/9))) - (16/9)π m^2
Step-by-step explanation:
To find the area of the shaded region, we need to subtract the area of the sector from the area of the triangle formed by the radius and the two radii connecting to the endpoints of the central angle.
First, let's find the area of the sector:
The formula for the area of a sector is (θ/360) * π * r^2, where θ is the central angle and r is the radius.
Given that the radius is 2 m and the central angle is 160°, we have:
θ = 160°
r = 2 m
Converting the angle to radians:
θ_radians = (160° * π) / 180° = (8π/9) radians
Now, we can calculate the area of the sector:
Area_sector = (θ_radians / (2π)) * π * r^2
= (8π/9) / (2π) * π * 2^2
= (4/9) * π * 4
= (16/9)π m^2
Next, let's find the area of the triangle:
The formula for the area of a triangle is (1/2) * base * height.
The base of the triangle is equal to the length of the radius, which is 2 m.
The height of the triangle can be found using the formula h = r * sin(θ/2).
θ = 160°
r = 2 m
Converting the angle to radians:
θ_radians = (160° * π) / 180° = (8π/9) radians
Calculating the height:
h = 2 * sin(θ_radians/2)
= 2 * sin((8π/9)/2)
= 2 * sin(4π/9)
= 2 * (√(1 - cos(4π/9)^2))
= 2 * (√(1 - cos^2(4π/9)))
Now, we can calculate the area of the triangle:
Area_triangle = (1/2) * base * height
= (1/2) * 2 * 2 * (√(1 - cos^2(4π/9)))
= 2 * (√(1 - cos^2(4π/9)))
Finally, we can find the area of the shaded region by subtracting the area of the sector from the area of the triangle:
Area_shaded_region = Area_triangle - Area_sector
= 2 * (√(1 - cos^2(4π/9))) - (16/9)π m^2
This is the exact answer in terms of π, with the correct unit of measurement (m^2).

as much as the souvenir, and the souvenir cost
2
3
the cost of the pass. Mark had $4.50 left over after buying these items.
What was the cost of each item?
The cost of the burger is $10.50, the cost of the souvenir is $28.00, and the cost of the pass is $42.00.
Let's assume the cost of the pass is x dollars.
According to the given information:
The burger costs 1/4 of the souvenir, so the burger's cost is[tex](1/4) \times x[/tex]dollars.
The souvenir costs 2/3 of the pass, so the souvenir's cost is [tex](2/3) \times x[/tex]dollars.
Mark had $4.50 left over after buying these items, so we can set up the following equation:
[tex]43.00 - [(1/4) \times x + (2/3) \times x] = $4.50[/tex]
Simplifying the equation, we have:
[tex]43.00 - [(1/4) \times x + (2/3) \times x] = $4.50[/tex]
[tex]43.00 - (1/4 + 2/3) \times x = $4.50[/tex]
[tex]43.00 - (3/12 + 8/12) \times x = $4.50[/tex]
[tex]43.00 - (11/12) \times x = $4.50[/tex]
To solve for x, we'll isolate the variable on one side of the equation:
$43.00 - $4.50 = (11/12) * x
$38.50 = (11/12) * x
Now, we can solve for x by multiplying both sides of the equation by (12/11):
[tex](12/11) \times $38.50 = x[/tex]
$42.00 = x
Therefore, the cost of the pass is $42.00.
Now we can find the costs of the burger and the souvenir:
The burger costs 1/4 of the souvenir, so its cost is (1/4) * $42.00 = $10.50.
The souvenir costs 2/3 of the pass, so its cost is (2/3) * $42.00 = $28.00.

In the given equation, the coefficient of x on the left side is 0 (since 3(x - 5) - 7 does not have an x term), and the coefficient of x on the right side is a.
For the equation to have a solution, the coefficients of x on both sides should be equal.
Therefore, we need to equate 0 and a:
0 = a.
If a = 0, then the equation has a solution. However, if a ≠ 0, then there is no solution.
Therefore, whether the equation 3(x - 5) - 7 = ax + b has a solution depends on the value of a.

Find the measure of the arc or angle indicated. Assume that lines which appear tangent are tangent.
Applying the angle of intersecting secant-tangent theorem, the measure of arc VT is calculated as: m(VT) = 116°.
How to Find the Measure of Arc Using the Angle of Intersecting Secant-Tangent Theorem?Given that the lines appear tangent, the measure of the arc VT indicated above can be calculated using the angle of intersecting secant-tangent theorem which states that:
m<U = 1/2(m(WT) - m(VT))
Given the following:
measure of angle U = 37 degrees.
measure of arc WT = 190 degrees.
Plug in the values:
37 = 1/2(190 - m(VT))
74 = 190 - m(VT)
m(VT) = 190 - 74
m(VT) = 116°

In a Leichtman Research Group survey of 1000 TV households, 74.8% of them had at least one Internet-connected TV device (for example, Smart TV, standalone streaming device, connected video game console). A marketing executive wants to convey high penetration of Internet-connected TV devices, so he makes the claim that the percentage of all homes with at least one Internet-connected TV device is equal to 78%. Test that claim using a 0.01 significance level. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.
W do not have sufficient evidence at the 0.01 level of significance to reject the claim made by the marketing executive
How to explain the normal distributionWe'll perform a one-sample z-test for proportions.
From the survey, we know:
Sample size (n) = 1000
Sample proportion) = 0.748
Under the null hypothesis:
Proportion (p0) = 0.78
Now we can calculate the z-score:
z = (0.748 - 0.78) / ✓(0.78 * (1 - 0.78)) / 1000]
= -0.032 / ✓(0.1716 / 1000]
= -0.032 / 0.0131
≈ -2.44
From the z-table, the P-value for -2.44 is approximately 0.015.
However, we need to double this value to get the two-tailed P-value: 2 * 0.015 = 0.03.
If the P-value is less than the significance level (α = 0.01), we reject the null hypothesis. In this case, the P-value (0.03) is greater than α, so we do not reject the null hypothesis.
Based on the data from the Leichtman Research Group survey, we do not have sufficient evidence at the 0.01 level of significance to reject the claim made by the marketing executive.

Answer:
[tex]x=(x-3)^{\frac{9}{5}}[/tex]
Step-by-step explanation:
The first thing we are going to do is change both sides of the equation to be base (x-3):
[tex](x-3)^{log_{(x-3)}(x)}=(x-3)^{\frac{9}{5}}[/tex].
Now, since the log is in base (x-3), the base (x-3) and the log cancel out:
[tex]x = (x-3)^\frac{9}{5}[/tex]
This is the final answer.
Find the determinant of a 10 x 10 matrix which had a 2 in each main diagonal entry and zeros everywhere else.
The determinant of the given 10 x 10 matrix is 1024.
What is a matrix?A matrix is described as a rectangular array or table with rows and columns and numbers, symbols, or expressions that is used to represent a mathematical object or a property of such an object.
We apply the knowledge that the determinant of a diagonal matrix is the product of its diagonal entries in order to find the determinant of a 10 x 10 matrix with 2s on the main diagonal and zeros elsewhere,
Determinant = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2
We then calculate for the product and have:
Determinant = [tex]2 ^ 1^0[/tex] = 1024
