Answer:

About 1 ride a day

Step-by-step explanation:

Answer:

Approximately 2.

Step-by-step explanation:

75 years and 365 days a year would be about 27,375 because we do not know which year he was born we cannot say how many leap years there are so we don't add that to the equation and we will just have to say that out answer is an approximation.

Now if he lived 27, 375 days then we divide the amount of car rides( 50, 000) by that number(50,000/27,375= 1.826484018264840182648401826484)

We can just round this to the nearest whole number which would be 2.

so the answer is approximately 2 car rides per day.

Answer:

d) 5 miles

Step-by-step explanation:

Minutes for jogging 1 mile is,

→ 36/3

→ 12 minutes

Formula we use,

→ Total time ÷ Time needed for 1 mile

Then the distance she cross in 60 min,

→ 60 ÷ 12

→ 5 miles

Hence, she will cross 5 miles.

In conclusion, we can use the if-else statement in Python to create a new variable with a value of 1 if the customer's predicted probability is greater than or equal to the breakeven response rate and 0 otherwise.

Given a prediction probability and a breakeven response rate, we need to create a new variable that takes the value of 1 if the customer's predicted probability is greater than or equal to the breakeven response rate and 0 otherwise. We can create this variable using an if-else statement in Python.The code to create the new variable "target" is as follows:```python

if predicted_prob >= breakeven_response_rate:

   target = 1

else:

   target = 0

```Where `predicted_prob` is the predicted probability of a customer responding to a marketing campaign, and `breakeven_response_rate` is the minimum response rate required for the campaign to break even. If `predicted_prob` is greater than or equal to `breakeven_response_rate`, `target` is set to 1. Otherwise, it is set to 0. This ensures that the new variable takes the value of 1 only for those customers who are likely to respond to the campaign, and 0 for those who are not likely to respond. The use of `if-else` statement helps us to create a logical condition that evaluates the predicted probability with the breakeven response rate.In conclusion, we can use the if-else statement in Python to create a new variable with a value of 1 if the customer's predicted probability is greater than or equal to the breakeven response rate and 0 otherwise. The code provided above uses this approach to create the variable "target". The length of the answer is 150 words.

Step-by-step explanation:

By standard deviation, The required number of motels that charged 118 or less per night is 87 (approx).

We are to determine how many motels charged 118 or less per night. We can use the normal distribution table to find out the z-score for the 75th percentile. We can then use this z-score to find out the price of lodging per night for the 118th percentile.

The formula to calculate the z-score is:\(z=\frac{X-\mu}{\sigma}\), where X is the price of lodging per night, \($\mu$\)is the mean rate, \($\sigma$\) is the standard deviation.

The z-score for the 75th percentile is found using the normal distribution table as: z = 0.67 (approx). For the 75th percentile, the motel charged $118 per night. Therefore, we can write the formula as:\(0.67 = \frac{118 - 91}{14}\) Simplifying, we get: \(0.67 = \frac{27}{14}\)

Therefore, we can conclude that:118 = 91 + 14 \(\times\) 0.67 Or, X = \(\mu\) + z\(\sigma\)= 91 + 0.67 \(\times\) 14 = 100.38. Thus, motels that charged 118 or less per night can be found as follows: \($$P(X \leq 118)\)=\(P(Z \leq z)$$$$\) = \(P(Z \leq 0.67)$$$$\)= 0.7486.

Hence, the number of motels that charged 118 or less per night is:

0.7486 \(\times\)116 = 87.06. Rounding it to the nearest integer, we get: 87 (approx). Therefore, the required number of motels that charged 118 or less per night is 87 (approx).

To obtain an unbiased sample for surveying the sandwich shop customers, the manager should choose a random selection method that ensures equal opportunity for all customers to be included in the survey.

To obtain an unbiased sample for surveying, the manager of the sandwich shop should choose a description that ensures all customers have an equal chance of being selected. Here are some options for an unbiased sample:

1. Random Selection: The manager randomly selects customers throughout the day, regardless of their demographic characteristics or purchasing behavior. This ensures a fair representation of the entire customer population.

2. Sequential Sampling: The manager surveys every nth customer who enters the shop during a specific time period. For example, every 10th customer entering the shop is selected for the survey. This method helps avoid any bias related to time or customer characteristics.

3. Stratified Sampling: The manager divides the customer population into distinct groups based on relevant characteristics (e.g., age, gender, or frequency of visits). From each group, a random sample is selected. This approach ensures representation from different customer segments.

4. Cluster Sampling: The manager selects specific clusters of customers, such as particular days or times, and surveys all customers within those clusters. This method can be useful when certain periods are expected to have different customer behaviors or preferences.

By employing any of these unbiased sampling methods, the manager can ensure that the survey results accurately reflect the opinions and preferences of the entire customer base, without favoring any particular group or biasing the outcomes.

The speed of the boat in still water is 8 miles per hour.

Let's call the speed of the boat in still water "x" (in miles per hour).

When Mackenzie rows downstream, the current is helping her, so the effective speed of the boat is (x + 4) miles per hour. The distance traveled is 96 miles. We can use the formula:

distance = rate × time

to set up an equation for the downstream trip:

96 = (x + 4) t

where "t" is the time (in hours) it takes for the downstream trip.

For the upstream trip, the current is working against Mackenzie, so the effective speed of the boat is (x - 4) miles per hour. The distance traveled is still 96 miles, but this time the trip takes 16 hours longer than the downstream trip. So we can set up another equation:

96 = (x - 4) (t + 16)

Now we have two equations with two unknowns (x and t). We can solve for t in the first equation and substitute into the second equation:

96 = (x - 4) (t + 16)

96 = (x - 4) (96/(x + 4) + 16)

Simplifying, we get:

96 = (x - 4) (96/(x + 4) + 16)

96 = 96(x - 4)/(x + 4) + 16(x - 4)

96(x + 4) = 96(x - 4) + 16(x + 4)(x - 4)

96x + 384 = 96x - 384 + 16(x^2 - 16)

96x + 384 = 96x - 384 + 16x^2 - 256

16x^2 = 256 + 384 + 384

16x^2 = 1024

x^2 = 64

A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. For any base n, q must be a factor of n in order for p/q to have a terminating base n representation.

A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. This can be seen by noting that if q is a factor of p, then p can be written as a multiple of q, or p = kq, where k is an integer. Thus, p/q = k, and the remainder of p divided by q must be 0. If q is not a factor of p, then the remainder of p divided by q will not be 0. Thus, for a rational number p/q to have a terminating base 60 representation, q must be a factor of 60. To determine if q is a factor of n for any base n, we must again consider the remainder of p divided by q. If the remainder of p divided by q is 0, then q is a factor of n, and the rational number p/q will have a terminating base n representation. If, however, the remainder of p divided by q is not 0, then q is not a factor of n and the rational number p/q will not have a terminating base n representation.

In the event that linear regression is required, we have two options: (1) change the delay column 2) ignore them.

A variable's value can be predicted using linear regression analysis based on the value of another variable. The dependent variable is the one you want to be able to forecast. The independent variable is the one you're using to make a prediction about the value of the other variable.

Given,

You want to run a regression to predict the probability of a flight delay, but there are flights with delays of up to 12 hours that are really messing up your model.

I immediately think of grouping delays into ranges such as those under 40 minutes, those between 40 minutes and 2 hours, those between 2 hours and 10 hours, and those above 10 hours. But doing so requires the use of a classification model, such as logistic regression. We frequently consider whether there will be a delay rather than how long it might last when thinking about delays. In the event that linear regression is required, we have two options: (1) change the delay column 2) ignore them.

The area of quadrilateral EDFG is approximately 21 cm²

We are given that 3DE = 3FC = AB.

Thus:

The area of ΔFCB = ¹/₆ * the area of ABCD

Area of ΔFCB = ¹/₆ * 140 = 23.33 cm²

Area of ΔCFG/Area of ΔCED = (CF/CE)²

Side length of ABCD is: CD = √140 = 11.83 cm

FC = 1/3 * CD

FC = 3.944 cm

CE = √(DE² + CD²)

CE = √(3.944² + 11.83²)

CE = 12.47 cm

Area of ΔCFG/Area of ΔCED = (3.944/12.47)² = 1/10

Area of ΔCFG = 1/10 * 140/6 = 2.33 cm²

Area of EDFG = (140/6) - (140/60) = 21 cm²

Answer:

Step-by-step explanation:

what abby wrote is conjecture,which is a statement know to be proven true

No,because she hasn't proven her statement.one way to do this is to use inductive reasoning.

We were told that the salary, t years after 2015 is given by the function,

S(t) = 3100t + 56000

When considering 2017, the number of years, t from 2015 is 2017 - 2015 = 2

We would substitute t = 2 into the function and find S(2)

Thus,

S(2) = 3100 x 2 + 56000 = 6200 + 56000 = 62200

When considering 2020, the number of years, t from 2015 is 2020 - 2015 = 5

We would substitute t = 2 into the function and find S(2)

Thus,

S(5) = 3100 x 5 + 56000 = 15500 + 56000 = 71500

Thus, we can say that

when

x1 = 2, y1 = 62200

when x2 = 5, y2 = 71500

Recall,

slope or average rate of change = (y2 - y1)/(x2 - x1)

average rate of change = (71500 - 62200)/(5 - 2) = 9300/3

average rate of change = 3100

ii. \(\overrightarrow{AC}\) = \(\overrightarrow{BC}\) - \(\overrightarrow{BA}\)

\(\overrightarrow{AN}\) = (2/7) × \(\overrightarrow{AC}\)

\(\overrightarrow{AN}\) = (2/7) × \(\overrightarrow{BC}\) - \(\overrightarrow{BA}\)

\(\overrightarrow{AN}\) = (2/7) × (p - q)

b. \(\overrightarrow{MN}\) = \(\overrightarrow{MA}\) + \(\overrightarrow{AN}\)

To model the distance (d) of point P from the surface of the water in terms of the number of seconds (t) the stopwatch reads, we can use the equation of a sine function. The equation would be:

                           d(t) = A * sin(B * t + C) + H,

where:

In this case, since point P reaches its maximum height three seconds after starting the stopwatch, the phase shift C would be π/2 (or 90 degrees). We can assume the baseline distance H is zero, as the problem does not mention any initial height above the water surface.

So, the equation that models the distance (d) in feet of point P from the surface of the water in terms of the number of seconds (t) the stopwatch reads would be:

                   d(t) = A * sin(B * t + π/2),

where A and B are constants that depend on the specific dimensions and characteristics of the waterwheel.
