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

'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.

Answer: got it correct

And yeah

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]

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.

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

Answer

10

Step-by-step explanation:

it takes 3/4 of a cup to make a mini loaves of bread and 3/4 is about one cup so 10

The number of mini-loaves that he could make with 10 cups of flour will be 25 cups.

From the complete information, it was stated that 1 cup of flour can be used to make 2.5 loaves.

Therefore, based on the information given, in order to calculate the number of mini-loaves that he could make with 10 cups of flour, we've to multiply the values. This will be:

= 2.5 × 10 = 25

In conclusion, the correct option is 25 cups.

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.

[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]
