Answer:

  (B)  -16 1/2

Step-by-step explanation:

To evaluate the expression for a certain variable value, put that value where the variable is in the expression and do the arithmetic.

  [tex]11\dfrac{1}{2}+\left(-4\dfrac{2}{3}\right)\cdot 6= 11\dfrac{1}{2}+(-4)(6) +\left(-\dfrac{2}{3}\right)\cdot6\\\\=11\dfrac{1}{2}-24 -4 =-\left(28-11\dfrac{1}{2}\right)=\boxed{-16\dfrac{1}{2}}[/tex]

The value of the z score form the normal distribution table will be 1.96, 2.58, 0.91, and 0.0014.

It should be noted that a normal distribution simply means a probability distribution which is symmetric about the mean.

From the complete question, value of the z score form the normal distribution table will be calculated thus:

P(-z < Z < z) = 0.95

1 - P(Z < - z) - P(Z > z) = 0.95

1 - P(Z > z) - P(Z > z) = 0.95

1 - 2 × P(Z > z) = 0.95

P(Z > z) = (1 - 0.95)/2 = 0.025

This will be 1.96 from the normal probability table.

For P(-z < Z < z) = 0.99

1 - P(Z < - z) - P(Z > z) = 0.99

1 - P(Z > z) - P(Z > z) = 0.99

1 - 2 × P(Z > z) = 0.99

P(Z > z) = (1 - 0.99)/2 = 0.005

This will be 2.58 from the normal probability table.

For P(-z < Z < z) = 0.64

1 - P(Z < - z) - P(Z > z) = 0.64

1 - P(Z > z) - P(Z > z) = 0.64

1 - 2 × P(Z > z) = 0.64

P(Z > z) = (1 - 0.64)/2 = 0.18

This will be 0.91 from the normal probability table.

For P(-z < Z < z) = 0.9973

1 - P(Z < - z) - P(Z > z) = 0.9973

1 - P(Z > z) - P(Z > z) = 0.9973

1 - 2 × P(Z > z) = 0.9973

P(Z > z) = (1 - 0.9973)/2 = 0.0014

This will be 2.99 from the normal probability table.

Therefore, the correct options are 1.96, 2.58, 0.91, and 0.0014.

Answer:

Step-by-step explanation:

7x/x = 7
-> 7*(x+10) = 7x +70 -> 7x-9 - (7x+70) = 0 - 79

Final result: 7(x+10)-79

Answer:

One solution

Step-by-step explanation:

To start, let's simplify the equations to slope-intercept form

y - 1/4x = =1

  +1/4x     +1/4x

y           = 1/4x - 1

y - 2 = 4x

  +2          +2

y       = 4x + 2

As you can see, the equations do not have anything in common worth mentioning. The slopes are different and the y-intercepts are different, so there must be only one solution.

Answer:

78

Step-by-step explanation:

250 - 172 = 78

Answer:

Step-by-step explanation:

An engagement ring is likely very precise. The ring sizes used by some jewelers differs from the next size by 0.8 mm. As a % that's .8 / 16.5  * 100 = 4.80 %

The 0.8 is the number of mm needed to go from a size 6 to a size 7 ring size. So if you are ever going to buy a ring, be sure and let a jeweler measure the finger that it will go on.

The 16.5 mm is the diameter of the ring in mm. for a size 6 ring. If you have different information, you should go with what you have,

Size 14 dress

I can't answer this: it depends on where you live -- Europe or the US.

Also the type of dress matters: is it a skirt or a skirt and blouse combination. The % of the sides is much larger than 4% for the ring but it is still a definite description.  

Small Medium or Large

Depends entirely on where the garment is made, and where it is being sold.

Wish tells you to add a size if you live in North America. This too is not very distinct.

Answer:

Triangle JKL

Step-by-step explanation:

The formula to find the area of a triangle is :area (A) =  (height (H) x base (B)) / 2

You are given the height and base of both triangles, so you just have to plug in the numbers.

Triangles JKL: A = (18 x 18) / 2

A = 162 in^2

Triangel XYZ: A = (16 x 20) / 2

A = 160 in^2

162 is greater than 160, so Triangle JKL has a larger area.

Answer:ABC has greater area

Answer: 78 eggs

Step-by-step explanation:

We can set up a ratio.

Let x be the amount of eggs in 13 cartons.

Then, [tex]\frac{1 carton}{6 eggs} = \frac{13 cartons}{x eggs}[/tex]

Now we can cross multiply and we get x = 78 eggs

The total number of eggs in the 13 cartons is 78.

Given the parameters:

Number of eggs in one carton = 6 eggs

Number of cartons = 13

Total number of eggs in 13 cartons =?

To determine the total number of eggs in 13 cartons, you simply multiply the number of eggs per carton (6) by the number of cartons (13).

Using the multiplication method:

Total number of eggs = Number of eggs in one carton × Number of cartons

Plug in the values:

Total number of eggs = 6 eggs/carton × 13 cartons

Total number of eggs = 6 eggs × 13

Total number of eggs = 78 eggs

Therefore, the total number of eggs is 78.

I am joyous to assist you at any time.

Answer:

210

Step-by-step explanation:

The mean=210

When your doing mean next time this is how you do it. you add up all the numbers so 210 225 206 214 180 and 225. The you divide by the total of numbers so there are a total of 6 numbers.

When you add up all these numbers it has a total amount of 1,260.

so what is 1,260 divided by 6? It=210.

Would you like to also know mode median and range.

Median=212
When you do median you sort the list of numbers least to greatest and the middle number is median now since there are an even amount of numbers you would use 3 and 4 since were on 6 and do the middle between them 2 so 210 and 214.

The middle number between them is 212 and that's your answer,

Mode=All the numbers above and for the list of numbers here,all the numbers appear the same amount of times because dealing with mode,mode is the number or numbers that appears most in the data set,and for this one they all appear once.

Range=45

Range is the highest number-the lowest number so 225-180=45.

Minimum is 180 because minimum is the lowest number in the data set.

Maximum is 225 because maximum is the highest number in the data set.

Hope it helps have a great day:)

Answer:

324pi

Step-by-step explanation:

V of sphere = 4/3 x pi x r^3

V of cone = pi x r^2 x h x 1/3

4/3 x pi x 6^3 = 288 pi

pi x 6^2 x 15 x 1/3 = 180 pi

since the sphere is cut in half = 288/2 = 144

144 pi + 180 pi = 324 pi

=====================================================

Explanation:

Problem 22

To get the cosine ratio, we divide the adjacent over hypotenuse.

cos(angle) = adjacent/hypotenuse

cos(x) = b/c

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

Problem 24

To get the sine ratio, we divide opposite over hypotenuse.

[tex]\sin\left(\text{angle}\right) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin\left(\text{x}\right) = \frac{2}{2\sqrt{17}}\\\\\sin\left(\text{x}\right) = \frac{1}{\sqrt{17}}\\\\\sin\left(\text{x}\right) = \frac{1*\sqrt{17}}{\sqrt{17}*\sqrt{17}}\\\\\sin\left(\text{x}\right) = \boldsymbol{\frac{\sqrt{17}}{17}}\\\\[/tex]

In the fourth step, I multiplied top and bottom by sqrt(17) to rationalize the denominator.

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

Problem 26

tan(angle) = opposite/adjacent

tan(x) = 2/8

tan(x) = 1/4

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

Problem 28

cos(y) = sin(x) in this case. The general rule is that sin(A) = cos(B) if and only if A+B = 90.

Therefore the answer is exactly identical to problem 24.

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

Problem 30

sin(30) = 1/2 is something you either memorize or look up on a reference chart, or use the unit circle. Alternatively, you can use a 30-60-90 triangle template.

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

Problem 32

[tex]\sin\left(45^{\circ}\right) = \boldsymbol{\frac{\sqrt{2}}{2}}\\\\[/tex] is something you memorize or have on a reference sheet. You could also use a 45-45-90 triangle.

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

Problem 34

[tex]\cos\left(30^{\circ}\right) = \boldsymbol{\frac{\sqrt{3}}{2}}\\\\[/tex] is similar to problems 30 and 32 in that you should memorize this or have it on a reference sheet. You could use a 30-60-90 triangle template here.

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

Problem 36

Let x be the length of side AC.

Use the tangent ratio to find x.

tan(angle) = opposite/adjacent

tan(B) = AC/AB

tan(31) = x/9

x = 9*tan(31)

x = 5.4077 approximately

Answer:

3(2v - 3)(3v + 2)

Step-by-step explanation:

18v² - 15v - 18 ← factor out 3 from each term

= 3(6v² - 5v - 6) ← factor the quadratic

consider the factors of the product of the coefficient of the v² term and the constant term which sum to give the coefficient of the v- term.

product = 6 × - 6 = - 36 and sum = - 5

the factors are - 9 and + 4

use these factors to split the v- term

6v² - 9v + 4v - 6 ( factor the first/second and third/fourth terms )

= 3v(2v - 3) + 2(2v - 3) ← factor out (2v - 3) from each term

= (2v - 3)(3v + 2)

Then

18v² - 15v - 18 = 3(2v - 3)(3v + 2)
