Step-by-step explanation:

The commonly used critical value for a 91% confidence level is approximately 1.70 (option a).

Given that the population appears to be very skewed and s is known, we can use the z-distribution to find the critical value.

For a 91% confidence level, we need to find the critical value za/2. This value represents the z-score corresponding to an area of (1 - 0.91) / 2 = 0.045 in the tails of the distribution.

Since the values given for the critical values do not match the common critical values for a 91% confidence level, we need to calculate the critical value za/2. However, the correct value depends on the specific z-table used. The commonly used critical value for a 91% confidence level is approximately 1.70.

Therefore, the correct answer is (a) za/2 = 1.70.

The complete question is:

Do one of the following, as appropriate: (a) Find the critical value za/2, (b) find the critical value ta/2, (c) state that neither the normal nor the t distribution applies.

91%; n = 45; s is known; population appears to be very skewed.

a. za/2 = 1.70

b. ta/2 = 1.645

c. za/2 = 1.75

d. ta/2 = 1.34

Explanation:

To find an area, you have to multiply the length/width of every side. Meaning you just have to do simple multiplication, which is:

20x4= 80

200x4= 800

100x4= 200

25x4= 100

As you can see, it is 100.

The vendor sold 172 sodas and 58 hotdogs at the hockey game.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

let, the number of soda cans be 'x' and the number of hot dogs be 'y'.

So, From the given information x = 3y and the vendor sold a total of 232.

Therefore, x + y = 232.

3y + y = 232.

4y = 232.

y = 232/4.

y = 58.

So, He sold 58 hot dogs and 3×58 = 172 soda cans.

Answer:

a

Step-by-step explanation:

in integer there will negative ,positive or rational number

The average velocity of the object after during the first three seconds is: 48m/s

The time at which the instantaneous velocity equals the average velocity within the first three seconds is 1.5 seconds.

Instantaneous velocity  is the speed of an object at a particular point in time.

Average velocity is the velocity of an object after covering a certain distance for a period of time

Analysis:

Given

initial height = 600 feet

Height with respect to time = f(t) = -16\(t^{2}\) + 600

a) Height at t = 0 = 600 feet

    Height at t = 3 seconds = f(3) = -16\((3)^{2}\) + 600 = 456 feet

Distance travelled  = 600 - 456 = 144 feet

Average velocity = distance travelled/time taken  = 144/3 = 48 feet/seconds

b) instantaneous velocity at time t = \(\frac{df(t)}{dt}\) = \(\frac{d(-16t^{2} + 600) }{dt}\) = -32t

  when instantaneous velocity equal average velocity

     -32t = -48

      t = 1.5 seconds

In conclusion, the Average velocity after 3 seconds is 48 feet per seconds and the time taken for the average velocity to equal the instantaneous velocity is 1.5 seconds.

Answer: its 40 because its a whole number

Step-by-step explanation:

Answer: (1) C. 65 + 28H < 250

(2) 6

Step-by-step explanation:

Here is the correct question:

Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of $65 along with an

hourly rate of $28. The plumber only charges for a whole number of hours. Anand would like to spend no more than $250, and he wonders how many hours of work he can afford.

Let H represent the whole number of hours that the plumber works.

1) Which inequality describes this scenario?

Choose 1 answer:

A. 28 + 65H < 250

B. 28 + 65H > 250

C. 65 + 28H < 250

D. 65 +28H > 250

2) What is the largest whole number of hours that Anand can afford?​

Since the initial fee charged by the plumber is $65 and an hourly rate of $28, and Anand would like to spend no more than $250. This means that the addition of the initial fee plus the hourly fee based on number of hours worked will have to be less than $250. This can be mathematically expressed as:

= 65 + 28H < 250

That means option C is the correct answer.

Option B and D are incorrect because the greater sign was used but Anand doesn't want to spend more than $250 but the options denoted that he spent more than $250 which isn't correct.

2)'The largest whole number of hours that Anand can afford goes thus:

65 + 28H < 250

28H < 250 - 65

28H < 185

H < 185/28

H < 6.6

Therefore, the largest whole number of hours that Anand can afford is 6.

Answer: The Answer is 65+28H < 250 and the largest amount of hours is 6

Step-by-step explanation:

The tangent line to the elliptical path at t = 13 is y = -0.24x + 0.352.

To find the tangent line to the elliptical path at t = 13, we need to find the derivative of y with respect to x at that point.

We have x(t) = 3cos(t) and y(t) = 4sin(t), so

dx/dt = -3sin(t)

dy/dt = 4cos(t)

Using the chain rule, we can find dy/dx as follows:

dy/dx = (dy/dt)/(dx/dt) = (4cos(t))/(-3sin(t)) = -(4/3) * cot(t)

At t = 13, we have x(13) = 3cos(13) ≈ -2.7 and y(13) = 4sin(13) ≈ 1.1.

To find the equation of the tangent line, we need a point on the line and its slope. The point is (-2.7, 1.1), and the slope is dy/dx evaluated at t = 13:

dy/dx|t=13 = -(4/3) * cot(13) ≈ -0.24

Therefore, the equation of the tangent line to the elliptical path at t = 13 is:

y - 1.1 = -0.24(x + 2.7)

Simplifying this equation gives:

y = -0.24x + 0.352

Answer:

f(x) / g(x) = x - 1   where x ≠ -1.

Step-by-step explanation:

f(x) / g(x) =   x² - 1 / x + 1

                = (x + 1)(x - 1) / (x + 1)

                = x - 1.

We have successfully found the inverse function of g(x) = 6 - (1/2)x, which is f(x) = -2x + 6. To find the inverse function of g(x) = 6 - (1/2)x, we need to interchange the roles of x and y and solve for y. The inverse function will have y as the dependent variable and x as the independent variable.

Let's begin by interchanging x and y in the original equation:

x = 6 - (1/2)y

Next, we solve for y:

2x = 6 - y

Subtracting 6 from both sides:

2x - 6 = -y

Multiplying both sides by -1 to isolate y:

y = -2x + 6

Thus, the inverse function of g(x) = 6 - (1/2)x is f(x) = -2x + 6.

To verify the inverse, we can compose the original function g(f(x)) and the inverse function f(g(x)) and check if they yield the identity function.

g(f(x)) = g(-2x + 6) = 6 - (1/2)(-2x + 6) = 6 + x - 3 = x + 3

f(g(x)) = f(6 - (1/2)x) = -2(6 - (1/2)x) + 6 = -12 + x + 3 = x - 9

Since both g(f(x)) and f(g(x)) simplify to x + 3 and x - 9, respectively, they are equal to the identity function.

The conversion of 24 mm into inches is 0.94488 inches.

Millimeter (mm) and inch are both units of length or distance, but they are used in different parts of the world.

A millimeter is a metric unit of length used in most countries outside the United States. It is equal to one-thousandth of a meter (1/1000 of a meter), or approximately 0.03937 inches.

To convert millimeters (mm) to inches, you can use the conversion factor of 1 mm = 0.03937 inches.

So, to convert 24 mm to inches, you can multiply 24 by 0.03937:

24 mm * 0.03937 inches/mm = 0.94488 inches

Therefore, 24 millimeters is approximately equal to 0.94488 inches.

Answer:

(a) Proof explained below

(b) The two lines are parallel

Step-by-step explanation:

(a) In the second equation express \(x\) in terms of \(y\) to get:

\(x=2y-8\)

Then, substitute \(x\) for \(2y-8\) in the first equation to get:

\(3(2y-8)-6y=-12\)

Open parentheses using the distributive property (\(a(b-c)=ab-ac\)) which results in:

\(6y-24-6y=-12\)

Combine like terms to reach:

\(-24=-12\), which is not true. Therefore, for any values of \(x\) and \(y\), the systems of equations will have no solutions.

Since the two lines have no solutions, that means that they are parallel.
