Answer:

Square

Step-by-step explanation:

In the given scenario, the nominal variables are Taia's income, the price of a digital movie rental, and the price of an americano. The real variables would be Taia's income adjusted for inflation, the real price of a digital movie rental, and the real price of an americano.

To calculate the real value of a variable, we need to adjust it for inflation using a suitable price index. As the question does not provide any information about inflation, we cannot calculate the real value of any variable.

Therefore, none of the options given in the question would give the real value of a variable.
Hi! I'd be happy to help you with this question. In the context of the classical dichotomy, real variables are quantities or values that are adjusted for inflation, while nominal variables are unadjusted values.

In the given scenario, Taia spends her income on digital movie rentals and americanos. We have the following information for 2016:

1. Hourly wage: $28.00 (nominal variable)
2. Price of a digital movie rental: $7.00 (nominal variable)
3. Price of an americano: $4.00 (nominal variable)

To determine the real value of a variable, we need to adjust these nominal values for inflation. However, the question does not provide any information about the inflation rate or a base year for comparison. Thus, we cannot calculate the real values for these variables in this scenario.

In summary, we do not have enough information to determine the real value of any variable in this case. Please provide the inflation rate or base year if you'd like me to help you calculate the real values.

Step-by-step explanation:

this is the answer

Answer:

He hiked 10 miles.

Step-by-step explanation:

rate x time = distance

The distance up and the distance down are equal

3 mi/1 hr  x (h hours + 2/3 hr) = 5 mi/1 hr  x  h hours

3h + 2 = 5h

2 = 2h

h = 1 hour

3mi/hr  x 1 2/3 hr = 5 miles

5 mi/hr x  1 hr = 5 miles

Since there are four tellers, the capacity of the bank in customers per hour = 4 x 7.5 = 30.

Valley Bank has four tellers. It takes a teller 8 minutes to serve one customer.

The correct option is D. 30.

We are given that

Valley Bank has four tellers. It takes a teller 8 minutes to serve one customer.

To calculate the capacity of the bank in customers per hour, we need to find how many customers each teller can serve in an hour. To do this, we first need to convert the time taken to serve one customer from minutes to hours.

1 minute = 1/60 hoursSo, time taken to serve one customer

= 8 minutes

= 8/60 hours

= 2/15 hours

One teller can serve one customer in 2/15 hours.In one hour, the number of customers one teller can serve = 1/(2/15) = 15/2 = 7.5 (customers/hour)

Therefore, the capacity of one teller in customers per hour is 7.5.

Now, we need to find the capacity of the bank in customers per hour. Since there are four tellers, the capacity of the bank in customers per hour = 4 x 7.5 = 30.

So, the correct option is D. 30.

The correct answer is option d) 60 cm^2.

The area of the triangle with side lengths 8 cm, 17 cm, and 15 cm can be calculated using Heron's formula. The correct answer can be found by substituting the side lengths into the formula and evaluating the expression.

To find the area of a triangle when the lengths of all three sides are known, we can use Heron's formula. Heron's formula states that the area of a triangle with side lengths a, b, and c is given by:

Area = sqrt(s(s - a)(s - b)(s - c))

where s is the semi-perimeter of the triangle, calculated as:

s = (a + b + c) / 2

In this case, the side lengths are given as 8 cm, 17 cm, and 15 cm. Plugging these values into the formula, we have:

s = (8 cm + 17 cm + 15 cm) / 2 = 20 cm

Area = sqrt(20 cm(20 cm - 8 cm)(20 cm - 17 cm)(20 cm - 15 cm))

     = sqrt(20 cm * 12 cm * 3 cm * 5 cm)

     = sqrt(3600 cm^2)

     = 60 cm^2

Therefore, the correct answer is option d) 60 cm^2.

The projection of the vector v onto the subspace S is [6 13 7].

The projection of the vector v onto the subspace S, we can use the formula for projection:

projᵥS = ((v⋅u₁)/||u₁||²)u₁ + ((v⋅u₂)/||u₂||²)u₂

where v is the vector we want to project, u₁ and u₂ are the basis vectors of the subspace S, ⋅ denotes the dot product, and || || represents the norm or magnitude of a vector.

In this case, the basis vectors of S are: u₁ = [1 1 0] u₂ = [0 1 1]

The vector v is: v = [4 8 6]

Now we can calculate the projection:

projᵥS = ((v⋅u₁)/||u₁||²)u₁ + ((v⋅u₂)/||u₂||²)u₂

Step 1: Calculate the dot products

v⋅u₁ = [4 8 6]⋅[1 1 0] = 4 + 8 + 0 = 12

v⋅u₂ = [4 8 6]⋅[0 1 1] = 0 + 8 + 6 = 14

Step 2: Calculate the norm squared

||u₁||² = ||[1 1 0]||² = (1² + 1² + 0²) = 2

||u₂||² = ||[0 1 1]||² = (0² + 1² + 1²) = 2

Step 3: Calculate the scalar factors

((v⋅u₁)/||u₁||²) = 12/2 = 6

((v⋅u₂)/||u₂||²) = 14/2 = 7

Step 4: Calculate the projection:

projᵥS = 6[1 1 0] + 7[0 1 1] = [6 6 0] + [0 7 7] = [6 13 7]

Therefore, the projection of the vector v onto the subspace S is [6 13 7].

(a) The coefficients for testing this contrast are -1, 2, and -1. (b) \(n_{1}\)= \(n_{2}\) = \(n_{3}\) = 16, Degrees of freedom = 45, If the P-value is smaller than the significance level (e.g., α = 0.05), we reject the null hypothesis and conclude that there is evidence to support the hypothesis that the average growth at 50% vegetation control is less than the average growth at 0% and 100% control levels.

(a) To test the contrast hypothesis that the average growth at 50% vegetation control is less than the average growth at 0% and 100% control levels,

we can set up the following contrast coefficients:

Contrast coefficients: c = [-1, 2, -1]

which indicate the weight or contribution of each group mean to the contrast. The first coefficient (-1) represents the weight for the 0% control group, the second coefficient (2) represents the weight for the 50% control group, and the third coefficient (-1) represents the weight for the 100% control group.

(b) To perform the test,

we can use the contrast coefficients to calculate the test statistic and P-value.

Test statistic (t-value):

t = (\(c_{1}\) × \(X_{1}\) + \(c_{2}\) × \(X_{2}\) + \(c_{3}\) × \(X_{3}\)) /  √ (\(sp^2\) × (\(c_{1}^{2} /n_{1}\) + \(c_{2} ^{2} /n_{2}\) + \(c_{3} ^{2} /n_{3}\)))  

where:

\(c_{1}\), \(c_{2}\), \(c_{3}\) are the contrast coefficients

\(X_{1}\), \(X_{2}\), \(X_{3}\) are the sample means for each control level

sp is the pooled standard deviation

\(n_{1}\), \(n_{2}\), \(n_{3}\) are the sample sizes for each control level

Using the given values:

\(c_{1}\) = -1,

\(c_{2}\) = 2,

\(c_{3}\) = -1

\(X_{1}\) = 58,

\(X_{2}\)= 73,

\(X_{3}\) = 105

sp = 17

\(n_{1}\) = \(n_{2}\) = \(n_{3}\) = 16

Calculating the t-value:

t = (-1 × 58 + 2 × 73 - 1 × 105) /  √ (\(17^2\) × (\(-1^2/16\) +\(2^2/16\) + \(-1^2/16\)))

Degrees of freedom:

df = \(n_{1}\) +\(n_{2}\) +\(n_{3}\) - 3

= 16 + 16 + 16 - 3

= 45

Using the calculated t-value and degrees of freedom,

we can determine the P-value from a t-distribution table or statistical software.

Step-by-step explanation:

For every pound of sweat you lose you need to drink 16 ounces of water!

Answer:

83.85%

Step-by-step explanation:

Given that:

Mean (μ) = 65 months, Standard deviation (σ) = 6 months.

The empirical rule states that about 68% of the data falls within one standard deviation (μ ± σ), 95% of the data falls within two standard deviation (μ ± 2σ) and 99.7% of the data falls within three standard deviation (μ ± 3σ).

For the question above:

68% of the data falls within one standard deviation (μ ± σ) = (65 ± 6) = (59, 71) i.e between 59 months and 71 months

95% of the data falls within one standard deviation (μ ± 2σ) = (65 ± 12) = (53, 77) i.e between 53 months and 77 months

99.7% of the data falls within one standard deviation (μ ± 3σ) = (65 ± 18) = (47, 83) i.e between 47 months and 83 months

The percentage of cars that remain in service between 47 and 59 months = (68% ÷ 2) + (99.7% ÷ 2) = 34% + 49.85 = 83.85%
