Principal =$300 rate = 7% time= 2 years

Total Time = t1 + t2 = (D / 1.4) + (D / 0.8) hours.

To find the time it takes for Dae to hike downhill and uphill, we can use the formula:

Time = Distance / Speed

1. For the downhill hike, Dae's speed is 1.4 miles per hour. Let's assume the distance is D miles. So the time it takes for the downhill hike is t1 = D / 1.4 hours.

2. For the uphill hike, Dae's speed is 0.8 miles per hour. The distance is still D miles. So the time it takes for the uphill hike is t2 = D / 0.8 hours.

Now, if we add the time it takes for the downhill hike (t1) and the uphill hike (t2), we get the total time for the round trip:

Total Time = t1 + t2 = (D / 1.4) + (D / 0.8) hours.

When checking the adequacy of a regression model, Correlation must be greater than alpha, option A.

A. Correlation is important for understanding the relationship between variables in a regression model but is not a requirement for assessing its adequacy.

Adequacy is determined by factors such as constant variance of residuals, mean of residuals close to zero, and approximately normal distribution of residuals.

B. The residuals should have a constant variance (homoscedasticity): This assumption ensures that the variability of the residuals is consistent across all levels of the independent variable(s).

C. The mean of the residuals is close to zero: This assumption suggests that the model is unbiased, and the residuals have no systematic bias in their average values.

D. The residuals are approximately normally distributed: This assumption implies that the residuals follow a normal distribution.

Departure from normality may affect the validity of statistical tests and confidence intervals.

These three requirements (B, C, and D) are important to ensure that the regression model provides accurate and reliable estimates of the parameters and produces valid statistical inferences.

Therefore, the correct answer is A. Correlation must be greater than alpha.

Answer:

f(x)=5-x

Step-by-step explanation:

Step-by-step explanation:

Find what 14.6 mi/hr is in f/s

14.6 mi / hr   *  1 hr / 3600 s  *  5280 ft / mi =  21.413 f/s

Then  distance / rate = time :

75 f  /  21.413 f/s = 3.5 sec

It would take Julio approximately 3.5 seconds to run from first base to second base at his top speed. Rounded to the nearest tenth of a second, it is approximately 3.5 seconds.

To calculate the time it takes for Julio to run from first base to second base, we first need to convert the distance between the bases from feet to miles.

1 mile = 5280 feet

So, 75 feet is equal to:

75 feet / 5280 feet per mile = 0.0142 miles (approximately, rounded to four decimal places)

Now, we'll use the formula for time:

Time = Distance / Speed

Time = 0.0142 miles / 14.6 miles per hour

Time ≈ 0.00097222222 hours

Now, we need to convert the time from hours to seconds:

1 hour = 3600 seconds

Time = 0.00097222222 hours * 3600 seconds per hour ≈ 3.5 seconds

So, it would take Julio approximately 3.5 seconds to run from first base to second base at his top speed. Rounded to the nearest tenth of a second, it is approximately 3.5 seconds.

Answer:

x:-4,-3,-2,-1,0,1

f(x):-10,0,0,-4,-6,0

from the table we can see when x=0, y=-6

Therefore the y-intercept will be (0,-6)

OAmalOHopeO

The y intercept of the continuous function in the table is given by the relation f ( 0 ) = -6

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

Let the values of x be x = { -4 , -3 , -2 , -1 , 0 }

Let the values of y be y = { -10 , 0 , 0 , -4 , -6 }

Now , the y intercept of the function is when the value of x = 0

So , when x = 0 , the value of y = -6

And , f ( 0 ) = -6

Therefore , the y intercept is ( 0 , -6 )

Hence , the y intercept of the function is ( 0 , -6 )

The volume of the prism is 145.89 cubic inches.

To find the volume of a prism, multiply the area of the base by the height of the prism.

We know the formula for the volume of a triangular prism is:

\(V = \frac{1}{2}\times b \times h\)

Where:

b represent the base area of a triangular prism.

h represent the height of a triangular prism.

Therefore, we can calculate the volume of the prism by cubing the length of one of its sides:

\(V = \frac{1}{2}\times 5.27\times 8.13 \times 6.81\)

\(V= \frac{291.775131}{2}\)

The area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Area of regular polygon = 1/2 × apothem × perimeter

perimeter = (s)side length of octagon × (n)number of side.

apothem = s/[2tan(180/n)].

11 = s/[2tan(180/12)]

s = 11 × 2tan15

s = 5.8949

perimeter = 5.8949 × 12 = 70.7388

Area of dodecagon = 1/2 × 11 × 70.7388

Area of dodecagon = 389.0634 in²

Area of pentagon = 1/2 × 5.23 × 7.6

Area of pentagon = 19.874 in²

Therefore, the area of the regular polygons with 12 sides(dodecagon) and 5 sides (pentagon) are 389.06 in² and 19.87 in² respectively.

Option c) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B

According to the information given in the question,

A true proportion of 0.325 represents that the two simulations will be conducted for sampling proportions from a population

Simulation A -

Sample size - 100

Trials - 1500

Simulation B -

Sample size - 50

Trials - 2000

Now due to the relation of simulation A and simulation B, they are closely equal-

The total sample size of simulation A= 1500 x 100

= 150000

The total sample size of simulation B = 2000 x 50

= 100000

From the above calculations of simulations A and B, we can see that while comparing the,

Sample Size = Simulation A > Simulation B

Variability = Simulation B < Simulation B

Therefore, option c) The centers will roughly be equal, and the variability of simulation A will be less than the variability of simulation B is correct.
