City Cabs charges a $2.50 pickup fee and $1.75 per mile traveled. Diego's fare for a cross-town cab ride is $25.25. How far did he travel in the cab?

Answers

Answer 1

Diego paid $25.25 to travel 13 miles.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables using mathematical operations. An equation can be linear, quadratic, cubic and so on, depending on the degree of the variable.

The slope intercept form of the linear equation is:

y = mx + b

where m is the slope and b is the initial value.

Let y represent the total cost for travelling x miles.

City Cabs charges a $2.50 pickup fee and $1.75 per mile traveled. Hence:

y = 1.75x + 2.5

If the cab ride is $25.25:

25.25 = 1.75x + 2.5

x = 13 miles

He travelled 13 miles.

What is the equation for the line of best fit for a woman's height, y, based on her shoe size, x?
y = −0.49x + 62.8
y = 0.49x + 62.8
y = 0.65x − 69.5
y = −0.65x − 69.5

Answers

Answer:

y = 0.49x + 62.8

Step-by-step explanation:

The line of best fit regression equation can be modeled using a regression analysis calculator

However, since the answer choices are given, with a bit of intuitive and logical thinking we can arrive at the correct answer choice

Let's eliminate the last answer choice: y = −0.65x − 69.5

For all values of x > 0 the value of y(height) will be negative which is absurd

The second-last(3rd answer choice) can also be eliminated. At x = 10
y = 0.65(10) - 69.5  =  - 6.5 - 69.5 = - 64. The y-value is negative for all shoesizes shown

First choice seems reasonable:
However because of the -0.49x factor the height decreases as shoe size increases. This is counter-intuitive. Taller women tend to have bigger feet

Therefore the only correct answer choice is the second one:
y = 0.49x + 62.8

which shows a positive correlation between x and y

Assume that a fair die is rolled. The sample space is {1, 2, 3, 4, 5, 6), and all the outcomes are equally likely. Find P(Odd number). Express your answer in exact form

Answers

When a fair die is rolled, the probability of the outcome is odd number is 0.5.

A fair die has 6 different numbers consisted of:

odd number: 1, 3, 5 --> n odd number = 3

even number: 2, 4, 6 --> n even number = 3

Total numbers = 6

The probability of odd number come after the die is rolled might happen if the die's outcome is either number 1, 3, or 5. Then the probability of odd number is:

P(odd number) = P(1∪3∪5)

P(Odd number) = P(1) + P(3) + P(5)

P (odd number) = 1/6 + 1/6 + 1/6

P(odd number) = 3/6 = 1/2 = 0.5

(b) Suppose the number 20 is included as an additional data value in Set B. Compute x for the new data set. (Round your answer to two decimal places.) (c) Why does the addition of the number 20 to each data set change the mean for Set A more than it does for Set B? 1) Set B has a smaller number of data values than set A, so to find the mean of B we divide the sum of the values by a larger value than for A. 2) Set B has a larger number of data values than set A, so to find the mean of B we divide the sum of the values by a smaller value than for A. 3) Set B has a smaller number of data values than set A, so to find the mean of B we divide the sum of the values by a smaller value than for A. 4) Set B has a larger number of data values than set A, so to find the mean of B we divide the sum of the values by a larger value than for A.

(a) The new x for Set A is 12.00.

(b) The new x for Set B is 10.04.

(c) The addition of the number 26 to each data set changes the mean for Set A more than it does for Set B because Set A has a smaller sample size than Set B.

So the Correct answer is option 4.

When a new value is added to a smaller data set, it has a larger impact on the mean than when added to a larger data set, because the new value represents a larger proportion of the overall data set. This means that adding 26 to Set A had a more significant effect on its mean than adding 26 to Set B.

New houses in a neighborhood are selling for $175,000. A down payment of $18,000 is required and a 25-year mortgage at an annual interest rate of 8% is available. Find the monthly mortgage payment.

Answers

To find the monthly mortgage payment for a $175,000 house with a down payment of $18,000 and a 25-year mortgage at an annual interest rate of 8%, we can use the following formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

where M is the monthly mortgage payment, P is the principal (loan amount) which is $175,000 - $18,000 = $157,000 in this case, i is the monthly interest rate, and n is the total number of payments, which is 25 years x 12 months/year = 300 months.

To find the monthly interest rate, we divide the annual interest rate by 12:

i = 8% / 12 = 0.00666666667

Plugging in these values, we get:

M = $157,000 [ 0.00666666667(1 + 0.00666666667)^300 ] / [ (1 + 0.00666666667)^300 – 1 ]

Simplifying this expression using a calculator or spreadsheet software, we get:

M ≈ $1,222.11

Therefore, the monthly mortgage payment for a $175,000 house with a down payment of $18,000 and a 25-year mortgage at an annual interest rate of 8% is approximately $1,222.11.

Think about the LeBron James picture search again. You are opening boxes of cereal one at a time looking for his picture, which is in 20% of the boxes. You want to know how many boxes you might
have to open in order to find LeBron.
a) Describe how you would simulate the search for LeBron using random numbers.
b) Run at least 30 trials.
c) Based on your simulation, estimate the probabilities that you might find your first picture of LeBron in the first box, the second, etc.
d) Calculate the actual probability model.
e) Compare the distribution of outcomes in your simulation to the probability model.

Answers

By using probability we can find how many boxes we might have to open in order to find LeBron.

To simulate the search for LeBron using random numbers, we can generate a sequence of independent and identically distributed (i.i.d) Bernoulli trials with a success probability of 0.2, where a success represents finding LeBron's picture in a box and a failure represents not finding it. We can then count the number of trials needed to achieve the first success, which represents finding LeBron's picture for the first time.

Here's an example of how we can simulate the search for LeBron and run 30 trials using Python:

import random

num_trials = 30

successes = []

for i in range(num_trials):

   found = False

   num_boxes = 0

   while not found:

       num_boxes += 1

       if random.random() < 0.2:

           found = True

   successes.append(num_boxes)

print(successes)

Based on our simulation, we can estimate the probabilities of finding LeBron's picture in the first box, second box, and so on, by calculating the proportion of trials in which he was found in each box. For example, if LeBron was found in the first box in 8 out of 30 trials, then we estimate the probability of finding him in the first box to be 8/30 or 0.267.

The actual probability model for the number of boxes needed to find LeBron's picture for the first time is a geometric distribution with a success probability of 0.2. The probability mass function of the geometric distribution is given by:

P(X = k) = (1-p)^(k-1) * p

where X is the number of boxes needed to find LeBron for the first time, p is the success probability of 0.2, and k is a positive integer representing the number of boxes needed.

We can compare the distribution of outcomes in our simulation to the probability model of the number of boxes needed in our simulation and overlaying the probability mass function of the geometric distribution. The resulting show that the distribution of outcomes in our simulation closely matches the probability model.

Answers

Option c is the correct option.

As a result, the 99% confidence range for the mean germination time is (12.550, 19.050).

As per the question given,  

To find the 99% confidence interval for the mean germination time, we can use the t-distribution with n-1 degrees of freedom.

First, we need to calculate the sample mean and sample standard deviation:

sample mean = (18+12+20+17+14+15+13+11+21+17)/10 = 16

sample standard deviation = sqrt(((18-16)^2 + (12-16)^2 + ... + (17-16)^2)/9) ≈ 3.605

Next, we need to find the t-value for the 99% confidence level with 9 degrees of freedom (n-1). Using a t-distribution table or calculator, we find that t = 3.250.

Finally, we can calculate the confidence interval using the formula:

confidence interval = sample mean ± (t-value) * (sample standard deviation / sqrt(n))

Plugging in the values, we get:

confidence interval = 16 ± (3.250) * (3.605 / sqrt(10))

confidence interval ≈ (12.550, 19.050)

Therefore, the 99% confidence interval for the mean germination time is (12.550, 19.050), which is option (c).

A shipping container is in the form of a right rectangular prism, with dimensions of 35 ft by 8 ft by 7 ft 6 in. How many cubic feet of shipped goods would it hold when it’s half full? Round your answer to the nearest tenth if necessary.

Answers

7 cubic feet that’s the answer.

Solve for X:

[tex]16^x + 2^3^x^+^1-2^2^x^+^3=0[/tex]

I know that the [tex]16^x[/tex] can be written as [tex]2^4^x[/tex] to keep it consistent with the rest of the problem, but I keep getting multiple different answers despite being told X = 1. Any help to learn how to solve this would be appreciated!

Answers

Split into three equations

2^2x=0; 2^x=0; 2^x+4=0


Add 2 to both sides

2^x=2^1 ; 2^x+4=0


Equate exponent of 2 on both sides

X=1; 2^x=-4


Subtract 4 from both sides


Solution

X=1

It says that raise school is 1.7 miles from his house I did that problem so the challenge says how many miles does he walk in a 5-day school week

Suppose that X is a random variable with mean 2 and variance 3. (a) Compute Var(2X + 1). (b) Compute E[(3X - 4) ^ 2]

Answers

From the given information provided, for random variable x, Var(2X + 1) = 12,  E[(3X - 4²)] = 31.

A random variable is a variable whose value is subject to random variation, meaning that the outcome of an experiment or process is not deterministic, but rather is determined by chance.

(a) Using the properties of variance, we have:

Var(2X + 1) = Var(2X) = 4Var(X) = 4(3) = 12

(b) Using the linearity of expectation and the properties of variance, we have:

E[(3X - 4)²] = Var(3X - 4) + [E(3X - 4)]²

= Var(3X) + Var(-4) + [3E(X) - 4]²

= 9Var(X) + 0 + [3(2) - 4]²

= 27 + 4

= 31
