Answer:

4.5.

Step-by-step explanation:

To find the median of a set of data, we need to first arrange the data in numerical order. Once the data is arranged in order, the median is the middle value in the set. In this case, the data arranged in numerical order is: 2.5, 3.5, 4.5, 5.5, 6.5. The median is the middle value, which is 4.5.

Answer:

The compound inequality that has no solution is 3(x+4) < 12 or 3x + 1 > 10. To solve this inequality, we need to first consider each inequality separately. For the first inequality, 3(x+4) < 12, we can solve for x by dividing both sides of the inequality by 3, like this:

(x+4) < 4

x < 0

This means that the solution to the first inequality is all values of x that are less than 0. For the second inequality, 3x + 1 > 10, we can solve for x by subtracting 1 from both sides of the inequality and then dividing by 3, like this:

3x > 9

x > 3

This means that the solution to the second inequality is all values of x that are greater than 3.

Now that we have the solutions to each inequality, we need to combine them to find the solution to the compound inequality. To do this, we need to consider the "or" that connects the two inequalities. This means that the solution to the compound inequality is the set of values that are either less than 0 or greater than 3. Since there are no values that are both less than 0 and greater than 3, this compound inequality has no solution. The other compound inequalities listed have solutions, so they are not the answer to the question.

The garden will stretch by 2/3 miles.

What do you mean by stretch ?

Stretch is to extend or lengthen something beyond the normal length.

Given that :

Garden covers an area of 1/6 of a square mile and the garden is 1/4 mile wide.

We know that,

      The garden is a rectangle in shape

Formula for area of rectangle

    Area of rectangle = length x breath

                         Area = l x b

substitute the given values in the formula , we get

     1/6 = l x (1/4)

     4/6 = 4 l / 4   [ multiply both sides with 4 ]

     4 / 6 = l

     2 / 3 = l         [ cancel by using 2 table ]

Therefore, the length of garden stretch when the garden covers an area of 1/6 of a square mile and the garden is 1/4 mile wide is 2/3 mile.

Answer:

g(x) = -x + 1|-2

Step-by-step explanation:

Negating the x-values flips everything over the y-axis. See attached for example

The value of the function f(x) = x when the limit x approaches to 0 is equal to 0.

As given in the function,

Given function is equal to:

f(x) = x

Value for the limit x approaches to zero

When x approaches to zero means x approaches to right hand side limit to zero or left hand side limit to zero

When limit x→0+ then the function f(x) = x is equal to 0

When limit x → 0- then the function f(x) = x is equal to 0.

[tex]\lim_{x \to 0} f(x)[/tex]

Answer: 10 burritos

Step-by-step explanation:

Let y be the total cost, and b is the number of burritos

So we have the equation is

y= 5.50b + 7

Now we put a total cost of $62 in the y spot

62 = 5.50b + 7

Subtract 7 from both sides

55 = 5.50b

Divide 5.50 from both sides

b = 10 burritos

Answer: 10 burritos

Step-by-step explanation:

This is a worded question. The first step would be to extract the essential information and represent it as an easily understandable equation:

b is the number of burritos

$5.50 is the cost for each burrito

$7 is additionally charged for a service fee

We have to find the number of burritos (b)

Therefore, we can write the equation like this:

(5.50 * b) + 7 = 62

We can then rearrange the equation to get b on one side. Remember to follow the BIDMAS rules backwards!

(5.50 * b) + 7 = 62

5.50*b = 62-7

5.50*b = 55

b = 55/5.50

b = 10

Finally, always write a worded answer because it is a worded equation. For example, you could write:

Marie bought 10 burritos

We have,

tan w = 0.0175

Multiply [tex]tan^{-1}[/tex] on both sides.

w = [tex]tan^{-1}[/tex] 0.0175

a) 0.7 % percentage of students taking the test had scores between 60 and 80.

b) 73.8% percentage of students taking the test had scores of at least 90.

c) 68% percentage of students taking the test had scores that were more than one standard deviation away from the mean.

d) The terms "probability distribution function" and "probability function" are also sometimes used to denote probability density functions. Probability Distribution Function can be used when the probability distribution is defined as a function over a general set of values. Alternatively, you can refer to the cumulative distribution function.

Let us assume that distribution is normal. As mean is 69.5

and standard deviation is 28.55,

z−score for 60 is (60-80)/ 28.55 = -0.7, and

z−score for 80 is (80-80)/28.55 = 0

Therefore, the area under the curve of the z result is −2 is 0.7. This is

z = +2 to z

  =0.7 (4 or z = 0 to z = −2).

So the percentage of values ​​between 60 and 80 is 0.7%.

b) (x > 90) = 1 - P( z < 90 - 69.5/ 28.55)

                 = 1 - (z < 0.71)

                 = 0.738

                 = 73.8%

Therefore, the percentage of students taking the test had scores of at least 90 is 73.8%.

c) The rule of thumb, or the 68-95-99.7% rule, falls within 1 standard deviation (68%), 2 standard deviations (95%), and 3 standard deviations (99.7%) of the mean Shows approximate percentage of data.

d) In probability theory, the probability density function (PDF) or continuous random variable density describes the value at a particular pattern (or point) in the pattern space (the set of possible values ​​taken by a random variable) as is a function that can be interpreted as Relative probability that the value of the random variable is close to this sample. Probability density is the probability per unit length. That is, the absolute probability that a continuous random variable will take on a particular value is 0 (because there is an infinite set of possible values ​​after all), but given the PDFs of two different samples, any random variable For a plot of , we can derive how much more likely the random variable is to be close to one sample than the other.

An exponential function has an opposite called a logarithmic function. In both exponential and log functions, the basis is the same.

An exponent and a number (the base) are inputs into a logarithmic function, which yields a result (the logarithm). The base that must be raised in order to obtain a number is represented by the number's logarithm.

The features of exponential functions can be investigated and exponential equations can be solved using logarithms. In calculus, where they are used to determine the slope of specific functions and the region enclosed by specific curves, they also become incredibly useful.

The probability they choose the same number is 0.1 or 1/10.

What is probability?

Mathematical descriptions of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between zero and one represents the likelihood of an event, with 0 roughly denoting impossibility and 1 denoting certainty. It is more likely that an event will occur if its probability is higher. The flip of a fair (impartial) coin serves as a straightforward illustration. Given that the coin is fair, the outcomes "heads" and "tails" are equally likely; therefore, the likelihood of "heads" equals the possibility of "tails"; since no other outcomes seem to be possible, the likelihood of either "heads" as well as "tails" is 1/2 (also known as 0.5 or 50%).

Whichever number the professor picks doesn't matter. The only thing that matters is that the student matches the predetermined number.

That probability is one-tenth(1/10) for any given number.

A simple random sample of tanks is selected and the sample mean capacity is found to be 8550 gallons. Therefore, The z score corresponding to a tank with a capacity of 8550 gallons is z = 0.50.

We can see that the actual capacity of the tank is normally distributed with a mean of 8544 gallons and a standard deviation of 12 gallons.

The actual capacity of the tank is normally distributed.

Let X = the actual volume of the tank

SO, X ~ Normal(μ = 8544 , σ² = (12)²)

The normal z-score probability distribution is given by:

                   Z = ~ N(0,1)

where μ = average capacity = 8544 gallons

           σ = standard deviation = 12 gallons

Z score measures how many standard deviations the measurements are from the mean To do. Once you have determined the Z-score, look at the Z-score table to find the p-value (area) associated with that Z-score. This p-value is the probability that the value of the measure is less than X. which means that Percentile of X.

Now,

The probability of a randomly selected tank having a capacity of less than 8550 gallons is given by = P(X < 8550 gallons)

   P(X < 8550 gallons) = P ( X - μ /σ < 8550 - 8544/12 )

                                     = P(Z < 0.50)

                                      = 0.6915

The above probabilities are calculated considering the value of x = 0.50 in a z-table with an area of ​​0.6915.

The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale." One kilometer on the ground is equal to one centimeter on a map with a scale of 1:100,000. There are three primary scale types found on maps: fractional scales, graphic scales, and written or verbal scales.

The link between the map's landscape and the one it shows is expressed using words in a written or verbal scale, for example, one inch equals one mile. To calculate distances and regions on a map, we can utilize the scale. Calculating distance is easy compared to converting scale types. Since we must square the integers, area computations are more difficult.
