This triple integral gives the volume of the right circular cylinder which is enclosed by the given surfaces and extends from z = 0 to z = -10.

What in mathematics is an integral?

Mathematicians define an integral as either a number equal to the area under the graph of a function for a certain interval or as a new function whose derivative is the original function (indefinite integral).

                       In general, the word "integral value" refers to the result of integrating or summing the terms of a function that has an infinite number of terms.

The triple integral that gives the volume of the right circular cylinder enclosed by the surfaces x^2 + y^2 = 4 , z=-10 and z=0 is:

∫∫∫dV = ∫∫∫dx dy dz

where the limits of the integration are:

0 ≤ x ≤ 2*sqrt(2), -2*sqrt(2) ≤ y ≤ 2*sqrt(2), 0 ≤ z ≤ -10.

This triple integral gives the volume of the right circular cylinder which is enclosed by the given surfaces and extends from z = 0 to z = -10.

TRUE - Procedure 2 has a larger test statistic and therefore will result in stronger evidence in favor of the alternative hypothesis.

Degrees of freedom are the maximum number of logically independent, or potentially different, values in the sample of data. One is subtracted from the number of elements in the data sample to determine the degree of freedom.

There are degrees of flexibility in the third column. Degrees of freedom (df1) between treatments equals k-1. df2 = N - k is the degree of freedom for the error. The total degree of freedom is N-1; additionally, (k-1) plus (N-k) equals N-1.

Fisher's Least Significant Difference (LSD) and the Bonferroni Method stand out among the techniques. These two use the t-test as their foundation. According to Fisher's LSD, run an F-test first, then if you find evidence to reject the null hypothesis, run regular t tests on all possible pairs of means. Similar but only requiring that you choose beforehand is the Bonferroni technique.

Answer:

No, the zeros of the function are at x = 3/4 and x = –2

Step-by-step explanation:

the equation

4x² + 5x – 6 = 0

(note: since there is a coefficient of x² we need to multiply it to the last term(6))

4x² + 5x – 24 = 0

the factors are :- 8x and – 3x

4x² + 8x – 3x – 6 = 0

4x( x + 2) –3( x + 2) = 0

( 4x – 3)( x + 2) = 0

the zeros will be

4x – 3 = 0

4x = 3

According to Riemann sum and expressing the work as an integral,400 ft/lb work is done in pulling the rope to the top of the building.

Given,

                             =  0.5 × 800 - 0

                             = 400 - 0

                             = 400 ft/lb

The statement that corresponds to P(X = 48), using continuity correction, is given as follows:

c. P(47.5 < x < 48.5).

Continuity correction is used as a "correction" when a continuous distribution is used to approximate a discrete distribution. One example of this is the approximation of the binomial distribution to the normal distribution.

Hence, using continuity correction, the range of values that corresponds to a number of exactly x is given as follows:

x - 0.5 < x < x + 0.5.

Thus the range for exactly 48 successes is of:

47.5 < x < 48.5.

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The given equation is 7m − 11 = 5m + 43.

It can be solved as follows,

7m − 11 = 5m + 43

⇒ 7m - 5m = 43 + 11

⇒ 2m = 54

⇒ m = 27

Now, in the given solution set  {2, 27, 54, 86}, only one integer 27 satisfies the given equation.

The mark-up, as a percentage =80%

What is Markup?

The term "markup" describes the discrepancy between a product's selling price and its actual cost. It is specified as a percentage over the price. In other words, the seller makes a profit when the price of the commodity.

A unit's gross profit, which is the sales price less the cost to create or buy it for resale, is divided by its cost to determine the markup %. The markup percentage is computed as (12 - 8) / 8 and is equal to 50% if an item costs the business $8 to produce but is sold for $12.

Markup percentage = [(selling price - unit cost)/unit cost]*100

                                 = [(900-500)/500]*100

                                 =  [ 400/500] *100

the vector function represents the curve of the intersection between a cylinder and a plane in 3-dimensional space.r(t) = (cos(t), sin(t), 2t)

The vector function represents the curve of the intersection between a cylinder and a plane. The function is given by r(t) = (cos(t), sin(t), 2t). This means that the x-coordinate of the point on the curve is given by cos(t), the y-coordinate of the point on the curve is given by sin(t), and the z-coordinate of the point on the curve is given by 2t.

The parameter t is defined as t [tex]$\in$[/tex] [tex][0, $\pi$/2],[/tex] which means that the domain of t is from 0 to [tex]$\pi$[/tex]/2. Therefore, the vector function represents the curve of the intersection between a cylinder and a plane in 3-dimensional space.

D flip flop stands for a delay flip flop that produces output that is identical to input after a brief delay. The flip flop's input and next state are equal.

Z is an output, and x and x inputs.

x'y + xA = DA= A*

B* = x'B + xA

z=A (output is independent of input) (output is independent of input)

The next states are A(t+1) and B(t+1). We must provide the next state value to D of the D flip flop in order to obtain the next states A(t+1), and B(t+1) for A, B(present state). So the sequential circuit will be:

To get the next state as A(t+1)= x’A + xA, B(t+1)= x’B + xA, we have to give them to DA, DB of D flip flop because for D flip flop whatever is given to DA, DB will appear at output A, B.
