Answers
The 218.63506 yd³ volume of the cone and the 4.9 yd radius of the cone indicates that the height of the cone is about 8.7 yards
h ≈ 8.7 yards
What is a cone?A cone is a three dimensional figure that has a circular base and a tapered surface that meets at a point on the top, such that the vertical cross-section of the cone is a triangle.
The volume of the cone = (1/3) × π × r² × h
Where;
r = The length of the radius of the circle
h = The height of the cone
The specified volume of the cone = 218.63506 yd³
The radius of the cone = 4.9 yards
The constant π ≈ 3.14
Therefore;
(1/3) × 3.14 × (4.9 yd)² × h = 218.63506 yd³
h = 218.63506 yd³ ÷ ((1/3) × 3.14 × (4.9 yd)²) = 8.7 yd

Answers
The best answer is E. We cannot tell if there is a solution for every b in R³.
To determine if the system Ax = b has a solution for every b ∈ R³, we need to examine the properties of matrix A. In this case, matrix A has dimensions 3x2,
which means it has more columns than rows. In general, if a system of linear equations has more variables than equations, it may not have a unique solution or a solution at all.
This is known as an overdetermined system. Since A has more columns than rows, it suggests that there may not be a solution for every b in R³.
However, without further information about the specific values of matrix A and the right-hand side vector b, we cannot definitively determine if there is a solution or not for every b in R³. Therefore, the correct answer is E.

39. The attendance at a weekly training program in the month of January averaged 116 people. If there were 105 people attending the first week, 106 the second, and 125 the third, how many people attended the fourth week? a. 118 b. 128 C. 130 d. 124
Answers
None of the provided options accurately represent the attendance for the fourth week based on the given information.
To find the number of people attending the fourth week, we need to calculate the average attendance for the month of January and then subtract the attendance of the first three weeks. Average attendance for the month of January = 116, Attendance for the first week = 105, Attendance for the second week = 106, Attendance for the third week = 125. Total attendance for the first three weeks = 105 + 106 + 125 = 336
To find the attendance for the fourth week, we subtract the total attendance for the first three weeks from the average attendance for the month: Attendance for the fourth week = Average attendance - Total attendance for the first three weeks, Attendance for the fourth week = 116 - 336, Attendance for the fourth week = -220
Since the result is negative, it implies that there was a decrease in attendance during the fourth week. However, the options provided for the answer (a, b, c, d) are all positive values. Therefore, none of the provided options accurately represent the attendance for the fourth week based on the given information.

Answers
A firm has two plants (X and Y) producing the same product which sells for $12 each. The total profit at plant X and plant Y are equal if the volume of each plant is 2,000 units.
To solve the problem, first translate the given problem into equations.
The formula for profit is:
profit = revenue from sales - total cost
total cost = fixed cost + variable cost
revenue = selling price x number of units sold
Let:
x = the number of units sold in plant X
y = the number of units sold in plant Y
From the problem, we can conclude:
Profit X = profit Y
x = y
Profit X = 12x - (5000 + 3x) (equation 1)
Profit Y = 12 y - (7000 + 2y) (equation 2)
Substitute y = x into equation 2
Profit Y = 12 x - (7000 + 2x)
Hence,
12x - (5000 + 3x) = 12 x - (7000 + 2x)
3x - 2x = 7000 - 5000
x = 2,000
Therefore, total profit at plant X and plant Y are equal if the volume of each plant is 2,000 units.

Answers
Thus, the interval estimate of the number of drivers under the age of 19 in 2008, together with its margin of error of 0.0245.
Explain about the confidence interval:An unknown population parameter's value is likely to be within the bounds of a confidence interval (CI), which is a range of values. Given the qualities of your sample data, these intervals reflect a likely domain for the parameter.
Confidence intervals are computed using a predetermined degree of confidence and are obtained from sample statistics.
Margin of error ME = z(α/2)√[p(1-p)/n]
confidence interval = 95%
z(α/2) value for the 95% confidence interval = 1.96 (taken from attached table)
P = 75% = 0.75
1-p = 1 - 0.75 = 0.25
n = 1200
Put the values in formula:
ME = (1.96)*√[0.75*0.25 / 1200]
ME = (1.96)*√0.00015625
ME = 0.0245

What is the value of this expression when a = 4, b = -5, and c = -7? a+2bc/3a
Answers
Answer:
To evaluate the expression a+2bc/3a when a = 4, b = -5, and c = -7, we need to substitute these values into the expression and perform the necessary calculations.
First, we can simplify the expression 2bc as follows:
2bc = 2(-5)(-7) = 70
Next, we can substitute these values into the original expression and perform the necessary calculations:
a+2bc/3a = 4 + 70/3(4)
= 4 + 70/12
= 4 + 5.83
= 9.83
Therefore, the value of the expression a+2bc/3a when a = 4, b = -5, and c = -7 is approximately 9.83.
A gymnast is performing a floor routine. In a tumbling run she spins through the air, increasing her angular velocity from 3. 40 to 5. 40 rev/s while rotating through one half of a revolution. How much time does this maneuver take
Answers
With given angular speed/velocity, the maneuver takes approximately 0.716 seconds.
What is angular speed ?Angular speed (ω) is a measure of how quickly an object is rotating around an axis or center point, and is given in units of radians per unit time (e.g., radians per second). It is also sometimes referred to as rotational speed.
Angular speed is related to the linear speed (v) of a point on the rotating object and the distance (r) of that point from the axis of rotation by the equation:
ω = v/r
Now,
As angular velocity
ω_avg = Δθ/Δt
where ω_avg is the average angular velocity, Δθ is the change in angle, and Δt is the time taken.
In this case, the gymnast rotates through half a revolution, or 0.5 × 2π radians = π radians. The initial angular velocity is ω1 = 3.40 rev/s, and the final angular velocity is ω2 = 5.40 rev/s.
We can use the formula for average angular velocity to find the time taken:
ω_avg = (ω1 + ω2)/2
ω_avg = (3.40 rev/s + 5.40 rev/s)/2
ω_avg = 4.40 rev/s
Δθ = π radians
Δt = Δθ/ω_avg
Δt = π/4.40 s
Δt ≈ 0.716 s
Therefore,
The maneuver takes approximately 0.716 seconds.

Use the fact that the mean of a geometric distribution is pi = 1/p and the variance is ohm^2 = p/q^2? b. How many cars do they expect to stop before finding a driver whose seatbelt is not buckled?
Answers
The mean of the number of drivers expected not to be wearing seatbelts is approximately 4.35, the variance is approximately 15.62, and the standard deviation is approximately 3.95 and they expect to stop approximately 4.35 cars before finding a driver whose seatbelt is not buckled.
a. To find the mean, variance, and standard deviation of the number of drivers expected not to be wearing seatbelts, we can model the situation using a geometric distribution.
Let's define a random variable X that represents the number of cars stopped until the first driver without a seatbelt is found. The probability of a driver not wearing a seatbelt is given as p = 0.23.
The mean (μ) of a geometric distribution is given by μ = 1/p.
μ = 1/0.23 ≈ 4.35
The variance (σ^2) of a geometric distribution is given by σ^2 = q/p^2, where q = 1 - p.
σ^2 = (0.77)/(0.23^2) ≈ 15.62
The standard deviation (σ) is the square root of the variance.
σ = √(15.62) ≈ 3.95
b. The expected number of cars they expect to stop before finding a driver whose seatbelt is not buckled is equal to the reciprocal of the probability of success (finding a driver without a seatbelt) in one trial. In this case, the probability of success is p = 0.23.
Expected number of cars = 1/p = 1/0.23 ≈ 4.35

Given z₁ = 4 cos(cos(π/4)+isin(π/4)) and z₂=2(cos(2π/3)+isin(2π/3)), i, find z₁z₂ ii, find z₁/z₂
Answers
z_1 and z_2 are complex number;
i) z₁z₂ = 8(cos(7π/12) + isin(7π/12))
ii) z₁/z₂ = 2(cos(π/12) + isin(π/12))
To calculate z₁z₂ and z₁/z₂, we need to perform the complex number operations on z₁ and z₂. Let's break down the calculations step by step:
i) To find z₁z₂, we multiply the magnitudes and add the angles:
z₁z₂ = 4cos(cos(π/4) + isin(π/4)) * 2cos(2π/3) + isin(2π/3))
= 8cos((cos(π/4) + 2π/3) + isin((π/4) + 2π/3))
= 8cos(7π/12) + isin(7π/12)
ii) To find z₁/z₂, we divide the magnitudes and subtract the angles:
z₁/z₂ = (4cos(cos(π/4) + isin(π/4))) / (2cos(2π/3) + isin(2π/3))
= (4cos((cos(π/4) - 2π/3) + isin((π/4) - 2π/3))) / 2
= 2cos(π/12) + isin(π/12)
i) z₁z₂ = 8(cos(7π/12) + isin(7π/12))
ii) z₁/z₂ = 2(cos(π/12) + isin(π/12))
Please note that the given calculations are based on the provided complex numbers and their angles.

Answer:
x+4 and y+3
Step-by-step explanation:
Both the x and y values move in positive directions from the first triangle to the second.
Answer:
(x+4, y+3)
Step-by-step explanation:
First, choose a point to follow (I chose C). The coordinates of C are (-2, -5). The coordinates of C' are (2, -2). To get to 2 from -2, you have to add 4. Move left or right because it's on the x-axis. Since it's moving you the right, it is positive. So, x+4 is the first part. To get from C to C', you have to move up to follow the y-axis, meaning another positive. Counting the units from (2, -5), because that is the point after x+4, there are 3 units. So, (x+4, y+3).
