Answer:

0.1359

step by step explanation

The area under the standard normal curve between z = -1.5 and z = 2.5 should be considered as the 0.9270.

Since

p value for z= -1.5 is 0.066807

p value for z= 2.5 is 0.99379

Now

area under the standard normal curve between z = -1.50 and z = 2.50. should be

= 0.99379-0.066807

= 0.926983

= 0.9270

Just think: which number would have the greatest value if it was rounded to the nearest hundredth

Answer: A

Step-by-step explanation:

I think the answer is correct becuase, If we taken all the numbers and put them on a number line they would all be under one. But when we look at the number line we would see that .987 is the closest because it is almost a whole number. And even if we did it without the number line what ever number we see that has the greatest digit and its in the negatives thats the closest to one. (I hope what I said makes sense!)

B. m∠A = \(tan^{-1}(\frac{20}{15} )\)

Step-by-step explanation:

Angle A has opposite side = 20 and adjacent side = 15

Using sohcahtoa method,

\(\frac{opposite}{adjacent} = tan(A)\)

\(\frac{20}{15} = tan(A)\)

\(tan^{-1}(\frac{20}{15} ) = A\)  .....this is the answer.

The answer is 1) V = \(2\pi\int\limits(2)+ {x} \, dx\); 2) V = \(2\pi \int\limits(1 - 2x) - 2x dx\); 3) V =\(2\pi \int\limits {\sqrt{2} } \, dx\) ; 4) V = \(2\pi\int\limits {\sqrt{(-2/2)(2-2)} \ dx\) .

1) The volume of the shell is then given by the product of the area of its curved surface and its height. The height is equal to 2 - (-2) = 4, and the radius is equal to the minimum of the distances from x = 2 to the two curves, which is x = 2 - () = 2 + . The volume of the solid is then given by the definite integral:

V = \(2\pi\int\limits(2)+ {x} \, dx\) = \(2\pi [(/3) + 2x]\) evaluated from 0 to 1 = (4/3)π.

2) The height of the region is equal to  - (2x) =  -2x, and the radius is equal to the minimum of the distances from x = 1 to the two curves, which is x = 1 - (2x) = 1 - 2x. The volume of the solid is then given by:

V = \(2\pi \int\limits(1 - 2x) - 2x dx\)=\(2\pi [/5 - 2/3 + /2]\) evaluated from 0 to 1 = (8π/15).

3) The height of the region is equal to (2-x) -  = 2-x. The radius is equal to the minimum of the distances from x = 0 to the two curves, which is x = The volume of the solid is then given by:

V =\(2\pi \int\limits {\sqrt{2} } \, dx\) = \(2\pi [(x^4/4)]\) evaluated from 0 to √2 = (π/2).

4) The height of the region is equal to () - (2-) = 2 - 2. The radius is equal to the minimum of the distances from x = 0 to the two curves, which is x = √((2-)/2). The volume of the solid is then given by:

Step-by-step explanation:

\(y = mx + b\)

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

\(9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y\)

\( \frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5\)

From y = mx+b, the slope is 3.

In calculating the factor A variation, there are two degrees of freedom. In determining the variation of factor B, there are two degrees of freedom.

A two-factor factorial design is an experiment that collects data for all potential values of the two factors of the study. The design is a balanced two-factor factorial design if equivalent sample sizes are used for every of the possible factor combinations.

Suppose we have two components, A and B, each of which has a high number of levels of interest. We will select a random level of component A and a random level of factor B, and n observations will be taken for each experimental combination.

From the data given:

Answer:

\(\frac{13}{\sqrt5}\)

Step-by-step explanation:

To get the shortest distance from a point to a line, we need to find a perpendicular line that intersects the line and also intersects the line. We know the slope of the line will be 1/2, but to find the y-intercept, we can just plug it into the point because we already know it will be on the line.

-3 = 1/2(-2)+c

-3 = -1+c

-2 = c

Now, we know the slope and the y-intercept, and since it will intersect the other line, we can set it equal to the other lines formula:

1/2x-2 = -2x+6

5/2x=8

x=16/5

Now, plugging this value of x into any of the equations, we can find the y-coordinate:

16/5(1/2)-2 = -2/5

We have the point (16/5, -2/5)

Now, we need to find the distance between (-2, -3) and (16/5, -2/5)

Plugging into distance formula:

\(\sqrt{(-2 - \frac{16}{5})^2+(-3-(-\frac{2}{5}))^2}\\= \sqrt{(-5.2)^2+(-2.6)^2}\\= \sqrt{33.8}\)

= \(=\frac{13}{\sqrt5}\)

A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15.

Given,

First three terms of an arithmetic sequence are x, 2x + 4, 5x

The difference of 1 and 2 term equals the difference of 3 and 2 term.

⇒ 2x + 4 - x = 5x - 2x - 4
