The theoretical probability of the spinner not landing on yellow, would be 75 %.
How to find the probability ?In order to calculate the likelihood of the spinner not landing on yellow, it is necessary to initially identify the quantity of non-yellow partitions and subsequently divide this by the full tally of sections. The spinner comprises a total of 8 individual segments.
Of these, two (i.e., sections 2 and 3) are colored in shades of yellow, hence totaling two yellow sectors. This leaves a further six compartments - numbered 1, 4, 5, 6, 7 and 8, that do not fall into the category of "yellow."
The probability is therefore :
= ( Number of not yellow sections ) / ( Total number of sections )
= 6 / 8
= 3 / 4
= 75 %

Answer:
We are given that:
- f(x) = x² - 2x - 4
- g(x) = x - 1We want to find fx for which f(x) = g(x) - 4, or in other words:
- f(x) = x - 1 - 4
- f(x) = x - 5
We can solve forTo find the value of x for which f(x) = g(x) - 4 (which is what I assume you meant by "f(x) = (x) = m - 4"), we can set up the following equation:
f(x) = g(x) - 4
Substituting the given expressions for f(x) and g(x), we get:
x² - 2x - 4 = x - 1 - 4
Simplifying, we have:
x² - 3x - 3 = 0
We can solve for x using the quadratic formula:
x = (-(-3) ± sqrt((-3)² - 4(1)(-3))) / (2(1))
x = (3 ± sqrt(21)) / 2
Therefore, the two values of x for which f(x) = g(x) - 4 are:
- x = (3 + sqrt(21)) / 2
- x = (3 - sqrt(21)) / 2
Find the length of the following parametric curve. x = 6 + it, y = 4 + 43/2, 03752. 0 << Enter your answer symbolically, as in these examples
To find the length of the parametric curve, we can use the formula:
L = ∫a^b √(dx/dt)² + (dy/dt)² dt
Substituting the given values, we get:
L = ∫0^1 √(6)² + (43/2, 03752)² dt
Simplifying:
L = ∫0^1 √(36 + (43/2, 03752)²) dt
Therefore, the length of the parametric curve is:
L = √(36 + (43/2, 03752)²)
In mathematics, substitution refers to the process of replacing a variable or expression in an equation or formula with another variable or expression that has the same value.
For example, if we have an equation: 2x + 3y = 7, and we want to substitute x with the value 4, we replace x with 4 to get:
2(4) + 3y = 7
8 + 3y = 7
We can then solve for y to find its value.
Substitution is a commonly used technique in algebra and calculus to simplify expressions, solve equations and evaluate functions.

Drake was trying to write an equation to help him predict the cost of his monthly phone bill.
He is charged $35 just for having a phone, and his only additional expense comes from the number of text that he sends,
He is charged $0. 05 for each text. Name the function C(t), where C(t) is the cost of bill according to number of text.
The function for Drake's monthly phone bill, C(t), is C(t) = 35 + 0.05t, where t represents the number of texts sent.
Drake has two components to his monthly phone bill: the base cost of $35 and the additional cost for texts sent. The base cost is fixed, meaning it does not change, so we can represent it as a constant value in the function (35).
The cost per text is $0.05, which means it varies depending on the number of texts sent (t). To find the total cost (C(t)), we need to add the fixed cost ($35) and the variable cost ($0.05 times the number of texts). Therefore, the function representing Drake's monthly phone bill cost is C(t) = 35 + 0.05t.

The derivative of the function y = 2(2^x)-2 is 12 * 2^x ln(2) or 12ln(2)x(2^x-1).
To find the derivative of the function y = 2(2^x)-2, we will use the power rule and the chain rule of differentiation.
Apply the power rule to the function y = 2(2^x)-2. The power rule states that if f(x) = x^n, then f'(x) = nx^(n-1).
y' = [2(2^x)-2]'

If a pair of jeans coast $14. 99 in 1973 when the CPI was 135, what would the price of jeans have been in 1995 if the CPI was 305
If the CPI was 305 in 1995, the price of jeans that cost $14.99 in 1973 would be approximately $47.05 in 1995 after adjusting for inflation.
To find the price of jeans in 1995, we first need to adjust the 1973 price for inflation using the Consumer Price Index (CPI). CPI measures the average change in prices of goods and services over time, so it can help us compare prices from different years.
First, we need to calculate the inflation rate between 1973 and 1995. We can do this by dividing the CPI in 1995 (305) by the CPI in 1973 (135):
Inflation rate = (305 / 135) * 100% = 226.67%
This means that prices in 1995 were about 2.27 times higher than in 1973. Now, we can apply this inflation rate to the price of jeans in 1973:
Price in 1995 = Price in 1973 * (1 + inflation rate)
Price in 1995 = $14.99 * (1 + 2.2667) = $47.05
Therefore, if the CPI was 305 in 1995, the price of jeans that cost $14.99 in 1973 would be approximately $47.05 in 1995 after adjusting for inflation. This calculation helps to compare the cost of goods across different time periods by taking inflation into account, thus giving a better understanding of the changes in purchasing power over time.

Answer:
x = 14°
t = 12.367 ~ 12.4
r = 2.999 ~ 3
Step-by-step explanation:
1st we can find x by sum theory which is the sum of all side equal to 180° .
x + 90° + 76° = 180 °
x + 166° = 180°
x= 180° - 166°
x = 14° ... So the unknown angle is 14°
and we also can solve hypotenus t and adjecent r by using sin amd cos respectively by angle 76° .
sin(76) = 12/t
sin(76) t = 12 ....... criss cross it
t = 12 / sin(76) ....... divided both side by sin(76)

This evaluated expression is a scalar multiple of -4, which projects that vectors CD and CE are collinear. Then, points C, D, and E lie on the same straight line.
Let us proceed by evaluating the vector CD. Then C is the midpoint of OA, we can evaluate the vector CD by subtracting vector CO from vector OD.
Vector CO = 1/2 × Vector OA
= 1/2 × (a + b)
= 1/2a + 1/2b
Vector OD = 3/4 × Vector AD
= 3/4 × (3/4a - 1/4b)
= 9/16a - 3/16b
Vector CD = Vector OD - Vector CO
= (9/16a - 3/16b) - (1/2a + 1/2b) = 5/16a - 5/16b
Then the value of the vector CE is
OB = 2BE,
we can evaluate the vector BE by dividing vector OB by 2.
Vector BE = 1/2 × Vector OB
= 1/2 × b
= 1/2b
Vector CE = Vector CO + Vector OE
Vector OE = Vector OB - Vector OE
= b - Vector BE
= b - 1/2b
= 1/2b
Vector CE = Vector CO + Vector OE
= (1/2a + 1/2b) + (1/2b)
= 1/2a + b
Then we have to show that vectors CD and CE are collinear. Two vectors are collinear if one is a scalar multiple.
CE can be expressed in terms of CD

a. How long does it take to hit the floor
b. How far from the table will it hit floor
Answer:
Step-by-step explanation:
a. To find the time it takes for the stone to hit the floor, we can use the formula t = sqrt(2h/g), where h is the height of the table and g is the acceleration due to gravity. Plugging in the values, we get:
t = sqrt(2(1.5 m)/9.8 m/s^2) = 0.55 seconds.
b. To find the horizontal distance traveled by the stone, we can use the formula d = vt, where v is the initial velocity of the stone and t is the time it takes to hit the floor. Plugging in the values, we get:
d = (0.80 m/s) * (0.55 s) = 0.44 meters.
Therefore, the stone will hit the floor after 0.55 seconds and will travel 0.44 meters from the table.

This rule ensures that the output will always be eight units smaller than the input. For example, if the input is 15, the output will be 7. This function rule can be used to perform calculations or model various scenarios where the output is consistently eight units less than the input.

When approximating mixed fraction 5 6/13 to the nearest whole number, the rounded value is 5.
To round the mixed fraction 5 6/13 to the nearest whole number, we examine the fractional part, which is 6/13. The general rule for rounding mixed fractions is to consider the fractional part and round up if it is greater than or equal to 1/2, and round down if it is less than 1/2.
In this case, 6/13 is approximately 0.4615. Since it is less than 1/2, we need to round down to the nearest whole number. Therefore, when rounding 5 6/13 to the nearest whole number, the answer is 5.
A mixed fraction consists of a whole number part and a fractional part. When rounding a mixed fraction, we focus on the fractional part to determine the appropriate rounding direction. If the fractional part is exactly 1/2, it is typically rounded up to the next whole number.
However, in the case of 5 6/13, the fractional part is less than 1/2, so we round down. Rounding down gives us a more accurate approximation that is closer to the original value. In this instance, rounding 5 6/13 down to 5 provides a whole number estimate that is slightly smaller but still reasonably close to the initial mixed fraction.
Rounding serves as a useful tool in situations where precise values are not necessary and a simpler approximation is sufficient for practical purposes.

Express the volume of the sphere x^2+ y^2 + z2 < 36 that lies between the cones z = √ 3x^2 + 3y^2 and z = √(x^2+y^2)/3
The volume of the sphere that lies between the two cones is approximately 43.53 cubic units.
How to calculate the volume of the sphereTo find the volume of the sphere that lies between the given cones, we first need to determine the limits of integration.
Since the sphere has a radius of 6 (since x² + y² + z² = 36), we can use spherical coordinates to express the volume as an integral. Let's first consider the cone z = √3x² + 3y².
In spherical coordinates, this is equivalent to z = ρcos(φ)√3, where ρ is the radial distance and φ is the angle between the positive z-axis and the line connecting the origin to the point.
Similarly, the cone z = √(x²+y²)/3 can be expressed in spherical coordinates as z = ρcos(φ)/√3.
Since we're only interested in the volume of the sphere between these cones, we can integrate over the limits of ρ and φ that satisfy both inequalities.
The limits of ρ will be 0 (the origin) to 6 (the radius of the sphere).
To find the limits of φ, we need to solve for the intersection points of the two cones.
Setting the two equations equal to each other, we get:
ρcos(φ)√3 = ρcos(φ)/√3
Solving for φ, we get:
tan(φ) = 1/√3 Using the inverse tangent function, we find that: φ = π/6, 7π/6
So the limits of integration for φ will be π/6 to 7π/6.
Finally, we need to integrate over the full range of θ (the angle between the positive x-axis and the line connecting the origin to the point).
This will be 0 to 2π.
Putting it all together, the volume of the sphere between the two cones is:
∫∫∫ ρ^2sin(φ) dρ dφ dθ
With limits of integration:
0 ≤ ρ ≤ 6 π/6 ≤ φ ≤ 7π/6 0 ≤ θ ≤ 2π
Evaluating this integral gives:
V = 288π/5 - 216√3π/5
So the volume of the sphere that lies between the two cones is approximately 43.53 cubic units.
