Answer:

Step-by-step explanation:

Here it is given that ,l ines PV , QW and RX are parallel .That is ,

[tex]\longrightarrow PV \ || \ QW \ || RX [/tex]

And we would like to find out the value of ,

[tex]\longrightarrow m\angle STW \ \& \ \angle TSV [/tex]

As we know that when a transversal intersects two parallel lines then ,

Here ,

[tex]\angle STW [/tex] and [tex]\angle TUX [/tex] are corresponding angles .So they must be equal.

[tex]\longrightarrow x = 2y \dots (i)[/tex]

Again here [tex]\angle VST[/tex] and [tex]\angle STW[/tex] are co- interior angles. So ,

[tex]\longrightarrow x + (x +5y) = 180^o \dots (ii) [/tex]

Substitute the value from equation (i) into (ii) ,

[tex]\longrightarrow 2y + 2y +5y =180^o \\[/tex]

[tex]\longrightarrow 9y = 180^o\\[/tex]

[tex]\longrightarrow y =\dfrac{180^o}{9}\\[/tex]

[tex]\longrightarrow y = 20^o [/tex]

[tex]\rule{200}4[/tex]

Therefore , we may find out the required angles as ,

[tex]\longrightarrow m\angle STW = x \\ [/tex]

[tex]\longrightarrow m\angle STW = 2y\\ [/tex]

[tex]\longrightarrow m\angle STW = 2(20^o)\\ [/tex]

[tex]\longrightarrow \underline{\underline{m\angle STW = 40^o}} [/tex]

[tex]\rule{200}4[/tex]

Again ,

[tex]\longrightarrow m\angle TSV = x + 5y \\ [/tex]

[tex]\longrightarrow m\angle TSV = 40^o 5(20^o)\\[/tex]

[tex]\longrightarrow m\angle TSV = 40^o + 100^o\\ [/tex]

[tex]\longrightarrow \underline{\underline{ m\angle TSV = 140^o }} [/tex]

And we are done!

[tex]\rule{200}4[/tex]

Answer:

5600 $

Step-by-step explanation:

1000 multiply by 5 = 5000 multiply by 12 percent

600 add by 5000

Using proportions, it is found that:

A. 165 students can be expected to oppose school uniforms.

B. From the sample, the most likely outcome is in favor, as it got the most responses, hence we should disagree with Bernice.

A proportion is a fraction of a total amount.

Item a:

Out of 80, 11 opposed, hence, out of 1200, we apply the proportion and find that the amount will be of:

1200 x 11/80 = 165.

Hence, 165 students can be expected to oppose school uniforms.

Item b:

From the sample, the most likely outcome is in favor, as it got the most responses, hence we should disagree with Bernice.

Let l be the symbol for length

Let w be the symbol for width

[tex]l = 2w - 5[/tex]

Our first equation is built according to the given that the length is twice the width subtracted by 5

Our second equation is built on the definition of perimeter. A perimeter is the sum of all sides of a polygon. A rectangle has 4 sides (2 lengths and 2 widths)

So the perimeter of a rectangle is=l+l+w+w=2l+2w

[tex]2l + 2w = 26[/tex]

This will be our second equation;

I can make a system of equations of 2 unknowns using my 2 equations;

[tex]2l + 2w = 26[/tex]

[tex]l -2w = - 5[/tex]

Add the two systems together by adding everything that is before the equal sign together and everything after it together.

[tex]2l + l + 2w - 2w = 26 - 5[/tex]

[tex]3l = 21[/tex]

[tex]l = \frac{21}{3} = 7 \: meters[/tex]

To find the width substitute L=7 in any equation;

[tex]l = 2w - 5[/tex]

[tex]7 = 2w - 5[/tex]

[tex]7 + 5 = 2w[/tex]

12=2w

w=12/2=6

The app is bugging, the width is 6 meters and the length is 7 meters

Answer:

2.983 ft/sec

Step-by-step explanation:

Given that

Distance between center and Jasmine riding on a carousal = 9.5 feet

Time taken to complete one rotation = 20 seconds

To find:

Jasmine's linear speed = ?

Solution:

Number of revolutions per minute = [tex]\frac{60}{20} = 3[/tex]

Formula for linear speed is given as:

[tex]v=\dfrac{2\pi}{60}\cdot r\cdot RPM[/tex]

Where [tex]r[/tex] is the radius of circular path and

[tex]RPM[/tex] is the number of revolutions per minute.

[tex]v=\dfrac{2\pi}{60}\times 9.5 \times 3\\\Rightarrow v=\dfrac{\pi}{10}\times9.5 \\\Rightarrow v = \bold{2.983\ ft/sec}[/tex]

Therefore, the linear speed is 2.983 ft/sec.

Answer:

When the discriminant of a quadratic function is negative than it is not be written in factored form.

Step-by-step explanation:

If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then

1. It is factorable if [tex]D=b^2-4ac\geq 0,[/tex] i.e., graph of function intersect the x-axis, roots of the function are real.

2. It is not factorable if [tex]D=b^2-4ac< 0,[/tex] i.e., graph of function does not intersect the x-axis, roots of the function are imaginary or complex.

It means, the quadratic function not be written in factored form when the discriminant of a quadratic function is negative.

A                       126               1.25

B                        98                  -2.772

C                        97                -0.26

D                        88                  -2.984

E                        66                -1.88

F                        95                  -2.801

G                        111                  0.47

H                        105                -2.539

B)For z = 2.00, test score =278.4

For z - -2.00, test score =125.6

Step-by-step explanation:

Student       Test Score     z-score

A                       126               1.25

B                        98

C                        97                -0.26

D                        88

E                        66                -1.88

F                        95

G                        111                  0.47

H                        105

Mean = [tex]\mu = 202[/tex]

Standard deviation = [tex]\sigma = 38.2[/tex]

For Student B

x= 98

[tex]Z=\frac{x-\mu}{\sigma}=\frac{98-202}{38.2}=-2.722[/tex]

For Student D

x= 88

[tex]Z=\frac{x-\mu}{\sigma}=\frac{88-202}{38.2}=-2.984[/tex]

For Student F

x= 95

[tex]Z=\frac{x-\mu}{\sigma}=\frac{95-202}{38.2}=-2.8010[/tex]

For Student H

x= 105

[tex]Z=\frac{x-\mu}{\sigma}=\frac{105-202}{38.2}=-2.539[/tex]

Now we are supposed to find test scores :

For z = 2.00

[tex]Z=\frac{x-\mu}{\sigma}\\2=\frac{x-202}{38.2}\\(2 \times 38.2)+202=x\\278.4=x[/tex]

For z = -2.00

[tex]Z=\frac{x-\mu}{\sigma}\\-2=\frac{x-202}{38.2}\\(-2 \times 38.2)+202=x\\125.6=x[/tex]

Hence ,For z = 2.00, test score =278.4

For z - -2.00, test score =125.6

Answer:

1. N,  2. S,  3. S, 4.  S, 5.  N*

Step-by-step explanation:

By "similar," I'm assuming you mean the same thing as "like" terms.  Those are exactly the same (same variables and same exponents) but could have different coefficients (the number in front).

1. N  variables are not the same

2. S  variables are the same, exponents are the same

3. S  same variables; same exponents (x^3 y^2 is the same as y^2 x^3)

4. S

5. N first term has z^2 in it; the second does not

Answer:

the container that holds

Answer: y=7/2 in decimal form 3.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2-4*y-(-12)=0

Pull out like factors :

  14 - 4y  =   -2 • (2y - 7)

  Solve  :    2y-7 = 0  

Add  7  to both sides of the equation :  

                     2y = 7

Divide both sides of the equation by 2:

                    y = 7/2 = 3.500

The middle of the upper half of a set of organized data is called the upper quarter.

We can divide the organized data in two halfs or in 4 quartiles (the interquartile range), where each quartile contains 25% of the data.

Such that each of the two halfs would be divided into two quartiles.

The middle of the upper half (where the third quartile ends and the fourth starts) is called the upper quarter.

So, concluding, the middle of the upper half of a set of organized data is called the upper quarter.

Step-by-step explanation:

Your question was this:

9+8/(-4)-12

I want you first to get rid of the -4-12 and be done with it so here are the steps:
Rule: If negative subtract a negative, that shall be an addition problem with the larger number's symbol.

In this case, we need to add 4 and 12 together and include the negative symbol in front of the answer.

That shall be -16

Our Question now:
9+8/-16

So do 9+8 which is 17.

Our question now:

17/-16

Your answer is an improper fraction so you could change it to a mixed number or you could simply divide 17 and -16 to get a negative decimal.
