M is the midpoint of RS. R has coordinates (-2,-3) and M has coordinates (1,0). Find the coordinates of S.

Answers

Answer:

[tex](4,3)[/tex]

Step-by-step explanation:

Given

[tex]R = (-2,-3)[/tex]

[tex]M = (1,0)[/tex]

Required

Determine the coordinates of S

Midpoint is calculated as:

[tex]M(x,y) = \frac{1}{2}(x_1 +x_2,y_1+y_2)[/tex]

Where:

[tex](x,y) = (1,0)[/tex]

[tex](x_1,y_1) = (-2,-3)[/tex]

Substitute these values in the above formula:

[tex](1,0) = \frac{1}{2}(-2 + x_2,-3+y_2)[/tex]

Multiply through by 2

[tex]2 * (1,0) = 2 * \frac{1}{2}(-2 + x_2,-3+y_2)[/tex]

[tex](2,0) = (-2 + x_2,-3+y_2)[/tex]

By direct comparison:

[tex]2 = -2 + x_2[/tex] and [tex]0 = -3 + y_2[/tex]

Solving for x2

[tex]2 = -2 + x_2[/tex]

[tex]x_2 = 2 + 2[/tex]

[tex]x_2 = 4[/tex]

Solving for y2

[tex]0 = -3 + y_2[/tex]

[tex]y_2 = 0 + 3[/tex]

[tex]y_2 = 3[/tex]

Hence, the coordinates of S is: [tex](4,3)[/tex]

it given that sin(-x) = -m where x is acute angle . express sec x in terms of m​

Answers

Answer:

[tex]\sec(x)=\frac{1}{\sqrt{1-m^2}}[/tex]

Step-by-step explanation:

We know that:

[tex]\sin(-x)=-m[/tex]

First, since sine is an odd function, we can move the negative outside:

[tex]=-\sin(x)=-m[/tex]

Divide both sides by -1:

[tex]\sin(x)=m[/tex]

We will now use the Pythagorean Identity:

[tex]\cos^2(x)+\sin^2(x)=1[/tex]

Substitute m for sine:

[tex]\cos^2(x)+m^2=1[/tex]

Solve for cosine:

[tex]\cos^2(x)=1-m^2[/tex]

Take the square root of both sides:

[tex]\cos(x)=\pm\sqrt{1-m^2}[/tex]

Since x is an acute angle, cosine will always be positive. Thus:

[tex]\cos(x)=\sqrt{1-m^2}[/tex]

Take the reciprocal of both sides. Hence:

[tex]\frac{1}{\cos(x)}=\sec(x)=\frac{1}{\sqrt{1-m^2}}[/tex]

Ms. Avella’s class volunteers at an animal shelter one day per week.each student is responsible for caring for four animals during every hour spent at the shelter

Please help

Answers

Answer:

Option (3)

Step-by-step explanation:

Since, every student is responsible for the caring of 4 animals during every hour,

Number of animals cared for ∝ Number of hours spent at shelter  

a ∝ h

a = kh

Here 'k' = proportionality constant

For h = 1 and a = 4,

k = [tex]\frac{h}{a}=\frac{4}{1}[/tex]

k = 4

a = 4h

By this equation,

For h = 2,

a = 8

For h = 3,

a = 12

For h = 4,

a = 16,

For h = 5,

a = 20

Since, for every input value there is a different output value,

Diagram shows a function.

Therefore, Option (3) will be the correct option.

Find the critical value zα2/ that corresponds to a 91% confidence level. Question 13 options: a) 1.7 b) 1.95 c) 1.81 d) 2.33 e) 2.57

Answers

Answer:

D

Step-by-step explanation:

2.33 I think

The critical value that corresponds to a 91% confidence level is 1.7

What is critical value?

'Critical value is a cut-off value that is used to mark the start of a region where the test statistic, obtained in hypothesis testing, is unlikely to fall in. In hypothesis testing, the critical value is compared with the obtained test statistic to determine whether the null hypothesis has to be rejected or not.'

According to the given problem,

Confidence level = 91%

Now, α = ( 100 - 91 ) %

             = 9%

             = 0.09

Area of each tail = [tex]\frac{0.09}{2}[/tex]

                             = 0.045

Area in the middle = 1 - 0.045

                               = 0.955

Now, if we look up this area on the z-table, the critical value will come as 1.6954, which is nearly equal to 1.7.

Hence, we can conclude, the critical value is 1.7.

lillian is a business woman of manufacturing phones. she must pay a daily fixed cost to rent the building and equipment and also pays a cost per phone produced for materials and labor. let c represent the total cost in dollars of producing p phones in a given day. the table below has select values showing the linear relationship between p and c. determine fixed cost for rent and equipment?

P: 2,4,6
C: 1200, 1400, 1600

Answers

Answer:

1000 dollars

Step-by-step explanation:

Given

P:  ---2 -----,4 ----,6

C: 1200, 1400, 1600

Required

Calculate the fixed cost

First, we need to determine the equation that determines the relationship between P and C

We start by selecting any two corresponding values of P and C

We have that:

[tex](P_1,C_1) = (2,1200)[/tex]

[tex](P_2,C_2) = (6,1600)[/tex]

Calculate the slope, using:

[tex]m = \frac{C_2 - C_1}{P_2 - P_1}[/tex]

[tex]m = \frac{1600 - 1200}{6 - 2}[/tex]

[tex]m = \frac{400}{4}[/tex]

[tex]m = 100[/tex]

The equation is then calculated using:

[tex]C - C_2 = m(P - P_2)[/tex]

Where

[tex]m = 100[/tex] and

[tex](P_2,C_2) = (6,1600)[/tex]

[tex]C - 1600 = 100(P - 6)[/tex]

[tex]C - 1600 = 100P - 600[/tex]

Collect Like Terms

[tex]C = 100P - 600 +1600[/tex]

[tex]C = 100P + 1000[/tex]

From the equation above,

100P represents the amount paid for P phones produced

1000 represents the fixed cost paid

C represents the total amount paid

A movie theater complex gave a poll as viewers exited from two theaters showing the same film. They had a 20% response rate from the people in theater A and a 30% response rate from the people in theater B. There were 800 people in total in theaters A and B.

Part A:​ It was estimated that an equal number of people from each theater responded to the poll. If this was the case, how many people in total would have been in theater A?

Part B:​ In reality, 440 people were in theater A and 360 people were in theater B. What was the total response rate for the poll? Express your answer as a percentage.

Answers

Answer:

Let´s define the variables:

x = number of people in theater A

y = number of people in theater B

We know that a 20% (or 0.2 in decimal form) of the people in theater A answered the survey, then the number of people from theater A that answered the survey is: Na = 0.2*x

We know that a 30% (or 0.3 in decimal form) of the people in theater B answered the survey, then the number of people from theater B that answered the survey is: Nb = 0.3*y

There where 800 people in total (counting from the two theatres)

Then x + y = 800.

A) In this case we have:

Na = Nb

this means that:

0.2*x = 0.3*y

and we also have the equation:

x  + y = 800

To solve this, we need to isolate one variable in one of the equations, i will isolate x in the second equation:

x = 800 - y

And now we can replace this in the other equation to get:

0.2*(800 - y) = 0.3*y

We need to solve this for y:

160 - 0.2*y = 0.3*y

160 = 0.3*y + 0.2*y = 0.5*y

160/0.5 = y = 320

Then there where 320 people in theater B, and:

x + y = 800

x + 320 = 800

x = 800 - 320 = 480

There where 480 people in theather A.

B) Now we have:

x = 440

y = 360

then:

Na = 0.2*440 = 88

In theater A, 88 people answered the survey.

Nb = 0.3*360 = 108

In theater B, 108 people answered the survey.

In total, 88 + 108 = 196 people answered the survey.

Answer:

D. The experimental probability is closer to the theoretical probability for group H than group G.

With any experimental probability, the more trials that are done will make the experiment move more likely to be the theoretical probability. in this case, the theoretical probability for flipping a coin is 50 heads 50 tails which H is closer to. any statistical data the more data collected the more close to reality it is.
