How do you find
the rate of change of a function?

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.

Step-by-step explanation:

Answer:

B. The experimental probability and the theoretical probability for group X is the same.

Answer:

x = 12

Step-by-step explanation:

Pythagorean triplet

12,16,20

So, the value of x is 12

x + 256 = 400

x = 400 - 256

x = 144

The square of 12 is 144

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

Work Shown:

Subtract the time values

131.25 - 119.5 = 11.75

This rounds to 12 when rounding to the nearest whole number.

This means she ran about 12 minutes faster. Since she ran 12 miles, this tells us she ran about 12/12 = 1 minute faster per mile.

The more accurate amount is 11.75/12 = 0.97916666666667 and we can see this is fairly close to 1. If we round to the nearest whole number, then we would get 1.

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:

[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

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:

c

Step-by-step explanation:

1. square the two smaller numbers and add them (5^2 + 12^2 = 169)

2. Take the square root of answer ( 13 )

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:

Well the answer would be 9.

Step-by-step explanation:

All you have to do is put 6 in the place of X. So the new equation would be 5x2+6-7, and all you do is solve that. So multiply 5 and 2 to get 10, than add 10 to 6 and get 16, 16 minus 7 to get your answer of 9.

[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]

Answer:

22 hours (B)

Step-by-step explanation:

John's velocity = 55mph

Sally's velocity = 65mph

John's time taken = x

Sally's time taken = x - 4

since they must cover the same distance.

and, distance = vel × time

Sally's vel × time = John's vel × time

55x = 65(x-4)

55x = 65x - 220

-10x = -220

x = 22 hours.

Therefore, Sally catches up after 22 hours

Answer: A

Step-by-step explanation: In all logic its only a 40 soemthing difference and its a bigger number so my guess is 6.1

The percentage decrease in the number of students will be 6.6%. The correct option is B.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that last year, Springfield Middle School had 620 students. This year, it has 582 students.

The percentage decrease will be calculated as:-

Percentage decrease = ( 620 - 582 ) / 582

Percentage decrease = ( 38 / 582) = 0.0652

Percentage decrease = 0.0652 x 100 = 6.52% ≅ 6.6%

Therefore, the percentage decrease in the number of students will be 6.6%. The correct option is B.
