The probability of waiting longer than one hour for a taxi is approximately 0.5488

Let X be the time between arrivals of taxis at the intersection. Then, X follows an exponential distribution with a mean of 10 minutes, i.e., E(X) = 10.

We want to find the probability of waiting longer than one hour (i.e., 60 minutes) for a taxi. Let Y be the waiting time for a taxi. Then, Y = kX, where k is a constant.

We can find k as follows

E(Y) = E(kX) = kE(X) = 10k

Since the mean waiting time is one hour (i.e., 60 minutes), we have

E(Y) = 60 minutes = 1 hour

Therefore, we get

10k = 1

k = 1/10

Now we can find the probability of waiting longer than one hour for a taxi as follows

P(Y > 60) = P(kX > 60) = P(X > 6) [since k = 1/10]

where the last step follows from the fact that X follows an exponential distribution with mean 10, so P(X > x) = e^(-x/10) for any x > 0.

Therefore, we get

P(Y > 60) = P(X > 6) = e^(-6/10) = e^(-0.6) ≈ 0.5488

The approximate area of the trapezoid is determined as  13.95 unit².

The approximate area of the trapezoid is calculated as follows;

Area = ¹/₂(b₁ + b₂)h

Where;

The y-coordinates of the points on the curve at x=3/2 and x=4 is calculated as follows;

y(3/2) = - (3/2)²/2 + 3/2 + 5

y(3/2) = -9/8 + 3/2 + 5

y(3/2) = 5.375

y(4) = -4²/2 + 4 + 5

y(4) = -8 + 9

y(4) = 1

h = 5.375 - 1 = 4.375

Answer:

The answer is 2.55

Step-by-step explanation:

As, the original price = $17

So, 85% of it have been reduced from it so

85% of 17

= 85/100 x 17 = 14.45

So it have reduced by $14.45

So, $17 - $14.45= $2.55

According to the given statement, the number of product lies on the x-coordinate axis while the the overall profit margin represents the y-coordinate axis.

The interpretation of the vertex (75,10000) shows that the maximum profit is 10,000dollars is reached when 75 items are produced. The vertex shows the maximum point on the curve.

For the x-intercepts at x = 0 and x = 150. Since the x-intercept is the point where there is no profit margin (y = 0), hence:

The x-intercept (0, 0) tells us that the profit will be 0 dollars when 0 items are produced,

The second root (150, 0) says once 150 items are made, the company is no longer making any profit.

Answer:kepler's 3rd law

Step-by-step explanation:

(a) To construct a 95% confidence interval for the mean difference in the estimates of the two methods (method 1 - method 2), we need first to find the sample mean difference and its standard error.

The sample mean difference can be calculated as follows:

mean_diff = mean(method 1 estimates) - mean(method 2 estimates)

And the standard error of the mean difference can be calculated as follows:

standard error = sqrt(variance(method 1 estimates)/n + variance(method 2 estimates)/n)

Where n is the sample size (n = 16 in this case).

Using these values, the 95% confidence interval can be calculated as follows:

mean_diff ± 1.96 * standard error

This interval gives us a range of values that we can be 95% confident contain the true population means the difference between the two methods.

(b) To determine whether our interval in part (a) gives convincing evidence of a difference in the two methods of estimating tire wear, we need to examine the confidence interval and determine whether it includes 0. If the interval includes 0, then we do not have convincing evidence of a difference between the methods, as the difference could be 0. If the interval does not include 0, then we have evidence of a difference between the methods.

Therefore, our interpretation of the interval will depend on the specific values obtained from the calculation.

The correct pairs pf points and axis of symmetry  are  (-1,-8) & y=-8 respectively.

The vertex of a parabola is the point at the intersection of the parabola and its line of symmetry. For a parabola whose equation is given in standard form , the vertex will be the minimum (lowest point) of the graph if and the maximum (highest point) of the graph if .

Given here; A parabola with upwards curve.

Now we know, The vertex is the highest point if the parabola opens downward and the lowest point if the parabola opens upward. The axis of symmetry is the line that cuts the parabola into 2 matching halves and the vertex lies on the axis of symmetry.

Thus we can clearly observe from the graph that (-1,-8) is the vertex of the parabola and we know the parabola is symmetric around its vertex.

Therefore the axis of symmetry of the parabola is y=-8

Hence, The correct pairs pf points and axis of symmetry  are  (-1,-8) & y=-8 respectively.

The equation of the inverse function of the function f(x) = x + 5 is f'1(x) = x - 5

Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function

The function f(x) is given as

f(x) = x + 5

As a general rule, we start by writing f(x) as a variable (say f(x) = y).

So, the equation of the function becomes

y = x + 5

The next step is to switch/swap the positions of x and y in the above equation y = x + 5

The equation becomes

x = y + 5

The next step is to make y the subject of the formula in the above equation x = y + 5

The equation becomes

y = x - 5

This is done by subtracting 5 from both sides of the equation.

So, we have:

y = x - 5

Express as an inverse function

f'1(x) = x - 5

Hence, the inverse function of the function f(x) = x + 5 is f'1(x) = x - 5

The number of students who do not buy lunch is 624 students - 420 students = 204 students.

The circle graph represents the proportion of students who buy lunch and those who don't. To find the number of students who don't buy lunch, we need to subtract the number of students who buy lunch from the total number of students.

Since 255° represents the proportion of students who buy lunch, we can use this to find the number of students who buy lunch. To do this, we divide the number of degrees by 360° and multiply by the total number of students, 624:

(255° / 360°) x 624 students = 420 students

Therefore, the number of students who do not buy lunch is 624 students - 420 students = 204 students.

Answer:

25% pay raise

Step-by-step explanation:

12.50-10.00=2.50

2.50/10.00=1/4

1/4=25%

The standard deviation and the mean are 16.95 and 86.43 respectively.

Z at 75% ≈ 0.674.

Since the spending is more than $75, Z = -0.674

Z at 15% ≈ - 1.036.

Since the spending is more than $104, Z = 1.036

Now,

Z = (x-mean)/SD => Z*SD = x-mean

Therefore,

-0.674*SD = 75 - mean ------- (1)

1.036*SD = 104 -mean ------- (2)

---------------------------------------------

(1) - (2)

-1.71SD = - 29 => SD = 75/1.71 = 16.95

Substituting SD in (1) => -0.674*43.8596 = 75 -mean => mean = 75+(0.674*43.8596) = 86.43.

Then,

SD = 16.95, mean = 86.43

What is permutation and combination?

The process of placing all the components of a set into a certain sequence or order is known as permutation in mathematics. In other terms, the process of permuting is the reordering of the components of a set if the set is already ordered. Nearly all areas of mathematics include permutations in some form or another. They frequently appear when various orderings on certain finite sets are taken into account.

Contrary to permutations, the order of selection is irrelevant when choosing elements from a collection using the combination method. The number of combinations may be counted in simpler situatiThe combinationation is the taking together of n items, k at a time, without repetition. The terms k-selection or k-combination with repetition are frequently used to describe combinations where repetition is permitted.

A function transfers each element's value from one set to a particular element in another set. When the value of x is -3, the function's value is -11.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

As the function's value is required to be rounded when the value of x is -3, we can write the function as follows:

\(f(-3) = 5\text{x} + 4\) Because x has a value of -3,

\(f(-3) = 5(-3) + 4\)

\(\bold{f(-3) = -11}\)

Hence, when the value of x is -3, the function's value is -11.
