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

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.

Answer:

x = 2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

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.

To interpolate a cubic spline between the points (0, 1), (2, 2), and (4, 0), we can use the concept of spline interpolation. A cubic spline is a piecewise-defined function consisting of cubic polynomials, which smoothly connects the given points.

In order to construct a cubic spline, we need to determine the coefficients of the cubic polynomials for each interval between the given points. The spline should satisfy three conditions: it must pass through each of the given points, it should have continuous first and second derivatives at the interior points, and it should have zero second derivatives at the endpoints to ensure a smooth connection.

We start by dividing the interval into three subintervals: [0, 2], [2, 4]. For each subinterval, we construct a cubic polynomial that satisfies the interpolation conditions. By imposing the continuity and smoothness conditions at the interior point (2, 2), we can obtain a system of equations. Solving this system gives us the coefficients of the cubic polynomials.

Once we have the coefficients, we can express the cubic spline as a piecewise function. The resulting cubic spline will smoothly connect the given points (0, 1), (2, 2), and (4, 0) and provide an interpolation function between them. This interpolation technique ensures a smooth and continuous curve, which can be useful for approximating values between the given data points.

Answer:

$20.60

Step-by-step explanation:

You find how much it costs for the total amount of basketballs (10.40×20=208), then you subtract that number from the total cost of everything to get the cost of all the uniforms (620-208=412), then you divide the total costs for all uniforms by 20 to find the cost for a single uniform (412÷20=20.6). Always make sure that the decimals go until the hundredths place for USD.

Using normal approximation, the probability that exactly 29 out of 108 eligible voters voted is approximately 0.2346, or 23.46%.

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

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

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).

Step-by-step explanation:

Step 1

We have to rearrange the given days set from least to highest

35, 40, 45, 55, 60

(a) the range

Range = The highest number - The least number

= 60 - 35

= 25

(b) the standard deviation of the data set

35, 40, 45, 55, 60.

We find the Mean

Mean = Sum of values/Number of values

= 35+40+45+55+60/5

= 235/5

= 47

We can find the standard deviation now.

The formula =

√(x - Mean)²/n

= √(35 - 47)²+ (40 + 47)² + (45 - 47)² + (55 - 47)² + (60 - 47)²/5

= √144 + 49 + 4 + 64 +169/5

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
