Answer:

32.202

Step-by-step explanation:

The hare can afford to nap for a maximum time of 3,690 seconds without losing the race if his speed is 15 m/s.

After running for 7 seconds, the hare has covered a distance of:

\(distance = speed \times time\\distance = 15 \times 7\\\)

distance = 105m

The hare is now 895 m away from the starting line and 100 m away from the finish line.

The hare needs to cover a distance of 100 m to reach the finish line, while the tortoise needs to cover a distance of 895 m.

calculate the time it would take the tortoise to reach the finish line:

\(time = \frac{100}{0.27}\) = 3704 seconds

The maximum speed of the hare is 15 m/s, which means the time it would take the hare to cover the distance is:

\(time = \frac{100}{15}\) = 6.67 seconds

so, the time hare have to nap so that he does not lose race = 3704 - (7+6.67) ≅3690 seconds

It is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

In the given scenario, it is not completely true that based only on the r and p values listed above, you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

Let's first understand what is meant by the term "moderator.

"Moderator: A moderator variable is a variable that changes the strength of a connection between two variables. If there is a statistically significant bivariate relationship between the amount of texting during driving and the number of accidents, scientists investigate whether this bivariate relationship is moderated by age.

Therefore, based on the values of r and p, it is difficult to determine if age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

As we have to analyze other factors also to determine whether the age is a moderator or not, such as the sample size, the effect size, and other aspects to draw a meaningful conclusion.

So, it is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

Answer:

-23.33

Step-by-step explanation:

C = 5/9 (F - 32)

C = 5/9 (-10 - 32)

C = 5/9 (-42)

C = -23.33

Answer: F. n = s/180 + 2

Step-by-step explanation:

         To find the equation that solves for n, we will isolate the n variable.

Given:

     S = (n - 2) x 180

Divide both sides of the equation by 180:

     \(\frac{S}{180}\) = n - 2

Add 2 to both sides of the equation:

     \(\frac{S}{180}\) + 2 = n

Reflexive property:

    n = \(\frac{S}{180}\) + 2

                   F. n = s/180 + 2

Answer: B.

Step-by-step explanation:

   First, we will solve both of these given inequalities for x by isolating the variables.

Given:

   6 + 3y < 9

Subtract 6 from both sides of the equation:

   3y < 3

Divide both sides of the equation by 3:

   y < 1

--

Given:

   4y > 3y + 2

Subtract 3y from both sides of the equation:

   y > 2

   Now, our given inequalities are y < 1 and y > 2. These inequalities are easier to view on the graph. We see that these are not equal to (≥ or ≤), so we will have open circles.

   First, we will graph y < 1. We will plot an open circle at y = 1 and then shade to the left of it. Net, we will graph y > 2. We will plot an open circle at y = 2 and then shade to the right of it. This leaves us with answer option B.

\(\frac{1}{3}(m-3) \leq \frac{1}{6}(m-12)\\\\2(m-3) \leq m-12\\\\2m-6 \leq m-12\\\\m-6 \leq -12\\ \\ m \leq -6\)

To calculate the difference in the amount of food pellets Al gives to the chickens compared to the combined amount given to rabbits and ducks, we need to convert the weights to the same unit.

Given information:

Rabbits: 0.3 kilograms

Chickens: 1,300 grams

Ducks: 0.7 kilograms

1 kilogram = 1,000 grams

Converting the weights to grams:

Rabbits: 0.3 kilograms = 0.3 * 1,000 = 300 grams

Ducks: 0.7 kilograms = 0.7 * 1,000 = 700 grams

Now we can calculate the difference in the amount of pellets given to the chickens compared to the combined amount given to rabbits and ducks:

Total weight of pellets given to rabbits and ducks = 300 grams + 700 grams = 1,000 grams

Difference = Weight of pellets given to chickens - Total weight given to rabbits and ducks

= 1,300 grams - 1,000 grams

= 300 grams

Therefore, Al gives 300 more grams of pellets to the chickens than he gives to the combined rabbits and ducks.

Al provides an additional 300 grams of pellets to the chickens compared to the combined amount given to rabbits and ducks.

The best way to remedy Ask customers throughout the day on both weekdays and weekends.

The cause of the bias in the survey is likely sampling bias. This means that the sample of 110 customers may not be representative of the entire population of food court shoppers. The bias can arise if the sample is not selected randomly or if certain groups of shoppers are overrepresented or underrepresented in the sample.

To remedy the sampling bias, the best way would be to  Ask customers throughout the day on both weekdays and weekends.

By surveying customers at different times, including both weekdays and weekends, a more diverse and representative sample can be obtained. This will help to capture the preferences of a wider range of food court shoppers and reduce the bias introduced by sampling only weekday mornings.

By the conjugate root theorem, both \(1+2i\) and \(1-2i\) are roots of \(f\).

The mean of a normally distributed group of weekly incomes of a large group of executives is $1,000 and the standard deviation is $100. Therefore, the z-score for an income of $1,200 is 2.

The z-score is a measure of how many standard deviations a particular value is away from the mean in a normal distribution.

To calculate the z-score, we use the formula:

z = (x - μ) / σ

where: - z is the z-score - x is the value we want to calculate the z-score for - μ is the mean of the distribution - σ is the standard deviation of the distribution In this case, we are given:

- μ = $1,000 (mean) - σ = $100 (standard deviation) - x = $1,200 (value for which we want to calculate the z-score)

Using the formula, we can calculate the z-score as follows: z = (1,200 - 1,000) / 100 z = 200 / 100 z = 2

Therefore, the z-score for an income of $1,200 is 2.

Answer:

75°

Step-by-step explanation:

I attached a diagram to try and help visualize this.

We are trying to find an unknown angle, x, on this line.

To start, we know we have a 162° angle. The question is a little weird, but it is essentially asking how big the right side would be if the left side is 87°.

simply take 162, and subtract 87. That would be the angle between Malcolm Way and Park Road.

162 - 87 = 75.

So, the angle between Malcolm Way and Park Road is 75°.

The percentage of tires that will have a life of 45,000 to 55,000 miles is  68.27%. So the correct option is 68.27%.

To find the percentage of tires that will have a life of 45,000 to 55,000 miles, we can use the concept of the normal distribution.

First, we calculate the z-scores for both values using the formula:
z = (x - mean) / standard deviation

For 45,000 miles:
z1 = (45,000 - 50,000) / 5,000 = -1

For 55,000 miles:
z2 = (55,000 - 50,000) / 5,000 = 1

Next, we look up the corresponding values in the standard normal distribution table. The table will provide the proportion of data within a certain range of z-scores.

The percentage of tires with a life between 45,000 and 55,000 miles is the difference between the cumulative probabilities for z2 and z1.

Looking at the standard normal distribution table, the cumulative probability for z = -1 is 0.1587, and the cumulative probability for z = 1 is 0.8413.

Therefore, the percentage of tires that will have a life of 45,000 to 55,000 miles is:
0.8413 - 0.1587 = 0.6826

Converting this to a percentage, we get:
0.6826 * 100 = 68.26%

So the correct answer is 68.27%.

The claim is given as follows:

"The mean weight of the fish in this reservoir is greater than 40 pounds".

At the null hypothesis, it is tested if there is not enough evidence to conclude that the claim is true, that is, not enough evidence to conclude that the mean is greater than 40 pounds, hence:

\(H_0: \mu \leq 40\)

At the alternative hypothesis, it is tested if there is enough evidence to conclude that the claim is true, hence:

\(H_1: \mu > 40\)

We are testing if the mean is greater than a value, hence this is a right-tailed test.
