1. The small bag of potting soil weighs 3 1/4 pounds. The large bag weighs 3 2/3 times more than the small bag. How much does the large bag weigh?
Answer:
11 11/12 lb
Step-by-step explanation:
"3 2/3 times more than the small bag" comes out to:
(3 2/3)*(3 1/4) lb.
Convert both mixed numbers to improper fractions:
11 13 143
--- * ---- = ----------- = 11.917
3 4 12
The large bag weighs 11.917 lb, which may be converted to the mixed number 11 11/12 lb

Answer:
m = 18/4 = 9/2 = 4.5
Step-by-step explanation:
Notice that the line passes through (0, 0) and (4, 18). Thus, its 'rise' is 18 - 0, or 18, and its 'run' is 4 - 0, or 4, and the slope (which is the desired constant of proportionality) is m = 18/4 = 9/2 = 4.5 This is Answer B

A set of dolls is made so that the volume,V of each of them varies directly as the cube of its height h. The doll with a height of 3cm has a volume of 6.75 cm³.
A) find an equation for V in terms of H.
B) find the volume of a doll with a height of 2.5cm
Answer:
A v=2.25 H=1
b. 5.625
Step-by-step explanation:
Answer:
V = 3.90625 cm³
Step-by-step explanation:
Given that V varies directly as h³ then the equation relating them is
V = kh³ ← k is the constant of variation
To find k use the condition
V = 6.75 when h = 3 , then
6.75 = k × 3³ = 27k ( divide both sides by 27 )
0.25 = k
V = 0.25h³ ← equation of variation
(b)
When h = 2.5 , then
V = 0.25 × 2.5³ = 3.90625 cm³

Find the value of the variables in the simplest form
Answer:
x = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (2[tex]\sqrt{2}[/tex] )² , that is
2x² = 8 ( divide both sides by 2 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2
5x^2 divided by -45x
Answer: -1/9 * x.
Step-by-step explanation:
To simplify the expression (5x^2) / (-45x), we can divide the coefficients and subtract the exponents:
(5 / -45) * (x^2 / x)
Simplifying the coefficient:
-1/9 * (x^2 / x)
Now, simplify the variables:
-1/9 * x^(2-1) = -1/9 * x
Therefore, the simplified expression is -1/9 * x.
Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that
108108
eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted.
Probability that exactly 29 voted
The probability that exactly 29 of 108 eligible voters voted is
Using normal approximation, the probability that exactly 29 out of 108 eligible voters voted is approximately 0.2346, or 23.46%.
What is the probability that exactly 29 out of 108 eligible voters voted?To find the probability that exactly 29 out of 108 eligible voters voted, we can use a normal approximation.
First, we need to calculate the mean (μ) and standard deviation (σ) for the binomial distribution, which can be approximated using the formula:
μ = n * p
σ = √(n * p * (1 - p))
where n is the number of trials (108 in this case) and p is the probability of success (22% or 0.22).
μ = 108 * 0.22 = 23.76
σ = √(108 * 0.22 * (1 - 0.22)) = 4.3
Next, we use the normal distribution to approximate the probability of exactly 29 voters. We will use the continuity correction by considering the interval between 28.5 and 29.5.
P(28.5 < X < 29.5) ≈ P(28.5 - 0.5 < X < 29.5 + 0.5) ≈ P(28 < X < 30)
To find this probability, we calculate the z-scores for 28 and 30 using the mean and standard deviation:
z₁ = (28 - μ) / σ
z₂ = (30 - μ) / σ
Then, we use a standard normal distribution table or calculator to find the probability associated with each z-score:
P(28 < X < 30) ≈ P(z₁ < Z < z₂)
Let's calculate the z-scores and find the corresponding probabilities:
z₁ = (28 - 23.76) / 4.61 ≈ 0.92
z₂ = (30 - 23.76) / 4.61 ≈ 1.35
Using the standard normal distribution table or calculator, we find the probabilities associated with these z-scores:
P(0.92 < Z < 1.35) ≈ 0.4082 - 0.1736 = 0.2346

Work:
V = πr²h
r² = V/(πh)
r² = 2000/(3.14 * 13)

A racing car is one of the many toys manufactured by Mack Corporation. The assembly time for this toy follows a normal distribution with a mean of 50 minutes and a standard deviation of 5 minutes. If one worker starts assembling a racing car, what is the probability that she will finish this job in more than 60 minutes? Find the z score? QUESTION 2 1 pol 1b. What do you get from Table A? QUESTION 3 3 point 10. What is the probability that she will finish this job in more than 60 minutos? (round to a percent with two decimals)
The probability that the worker will finish assembling the racing car in more than 60 minutes is approximately 0.1587. The z-score corresponding to 60 minutes is 2. The probability of completing the job in more than 60 minutes is 15.87%.
To find the probability that the worker will finish assembling the racing car in more than 60 minutes, we need to calculate the z-score and then find the corresponding probability from the standard normal distribution.
First, we calculate the z-score using the formula:
z = (x - μ) / σ
where x is the given time (60 minutes), μ is the mean (50 minutes), and σ is the standard deviation (5 minutes).
z = (60 - 50) / 5
z = 2
Next, we look up the probability corresponding to a z-score of 2 in Table A (standard normal distribution table). The value in the table represents the probability of a random variable being less than the given z-score. To find the probability of the worker finishing in more than 60 minutes, we subtract this value from 1.
From Table A, the probability corresponding to a z-score of 2 is approximately 0.9772.
Probability = 1 - 0.9772
Probability ≈ 0.0228
Therefore, the probability that the worker will finish assembling the racing car in more than 60 minutes is approximately 0.0228 or 2.28% (rounded to two decimal places).

An 18-foot ladder leaning against a wall makes an angle of elevation of 70° with the ground. How far up the wall is the ladder, to the nearest foot?
Answer:
17 ft
Step-by-step explanation:
An 18-foot ladder leaning against a wall makes an angle of elevation of 70° with the ground. How far up the wall is the ladder, to the nearest foot?
We solve the above question using the Trigonometric function of Sine
sine theta = Opposite/Hypotenuse
theta = Angle of elevation = 70°
Hypotenuse =Length of the ladder = 18ft
Opposite = Height of the wall = x
Therefore
sin 70 = x/ 18 ft
Cross Multiply
x = sin 70 × 18 ft
x = 16.914467174 ft
Approximately = 17 ft

Alternate Sources of Fuel Seventy-five percent of Americans favor spending government money to develop alternative sources of fuel for automobiles. For a random sample of 140 Americans, find the mean, variance, and standard deviation for the number who favor government spending for alternative fuels. Round your answers to three decimal places.
Part: 0/2 ______
Part 1 of 2
(a) Find the mean.
Mean: μ= _____
The mean number of Americans who favor government spending for alternative fuels can be calculated by multiplying the percentage of Americans who favor such spending by the total sample size. In this case, 75% of Americans favor government spending, and the sample size is 140.
Mean = (Percentage of Americans who favor government spending) * (Sample size)
= 0.75 * 140
= 105
Therefore, the mean number of Americans who favor government spending for alternative fuels is 105.
The mean represents the average or central tendency of the data. In this context, it indicates the average number of Americans in the sample who support government spending for alternative fuels. It is obtained by multiplying the percentage of Americans who favor such spending by the sample size.

Find all eigenvalues of the given matrix. (Enter your answers as a comma-separated list.) 1 0 0 00-4 A = 04 0 a = =
The eigenvalues of the given matrix A are 1, 2, and -2.
To find the eigenvalues of the matrix A:
A = [1 0 0]
[0 -4]
[0 4]
To find the eigenvalues, we need to solve the characteristic equation |A - λI| = 0, where λ is the eigenvalue and I is the identity matrix.
The matrix A - λI is:
A - λI = [1 - λ 0]
[0 -4]
[0 4 - λ]
Taking the determinant of A - λI:
|A - λI| = (1 - λ)(-4 - λ(4 - λ))
Expanding the determinant and setting it equal to zero:
(1 - λ)(-4 - λ(4 - λ)) = 0
Simplifying the equation:
(1 - λ)(-4 - 4λ + λ²) = 0
Now, we can solve for λ by setting each factor equal to zero:
1 - λ = 0 or -4 - 4λ + λ² = 0
Solving the first equation, we get:
λ = 1
Solving the second equation, we can factorize it:
(λ - 2)(λ + 2) = 0
From this equation, we get two additional eigenvalues:
λ = 2 or λ = -2
Therefore, the eigenvalues are 1, 2, and -2.
