The given fractions have equal value, so Liam is correct.

Equivalent fractions are defined as fractions that have different numerators and denominators but the same value. For example, 2/4 and 3/6 are equivalent fractions because they are both equal to 1/2. A fraction is part of a whole. Equivalent fractions represent the same part of a whole.  

Liam is claiming that the fraction -(5/12) is equivalent to 5/-12.

Thus, we can say that:

The fraction  -(5/12) can be described as the opposite of a positive number divided by a positive number. A positive number divided by a positive number always results in a positive quotient and its' opposite is always negative.

The fraction 5/-12 can be described as a positive number divided by a negative number which always results in a negative quotient

Answer:

Step-by-step explanation:

2x2+13x+6=0

(2x+1)(x+6)=0

2x+1=0 or x+6=0

x= -1/2 or x= −6

Graphing the equation 3x - 2y = -6 over the range x = -10 to x = 10:

To graph the equation 3x - 2y = -6, we need to rearrange it in the form y = mx + b, where m is the slope and b is the y-intercept.

3x - 2y = -6

-2y = -3x - 6

Divide both sides by -2:

y = (3/2)x + 3

Now we have the equation in slope-intercept form.

To graph the equation, we can plot a few points and draw a line through them. Let's choose some x-values from the range -10 to 10 and find the corresponding y-values.

For x = -10:

y = (3/2)(-10) + 3

y = -15 + 3

y = -12

For x = 0:

y = (3/2)(0) + 3

y = 0 + 3

y = 3

For x = 10:

y = (3/2)(10) + 3

y = 15 + 3

y = 18

Plotting these points (-10, -12), (0, 3), and (10, 18) on the graph and drawing a line through them, we get the graph of the equation 3x - 2y = -6.

Using the graphical method to solve the pair of equations:

The given equations are:

10x = 5y

-3x + y = 1

To solve these equations graphically, we need to plot their graphs on the same coordinate plane and find the point where they intersect, which represents the solution.

Rearranging the second equation in slope-intercept form:

y = 3x + 1

Now we have the equations in the form y = mx + b.

Plotting the graphs of the equations 10x = 5y and y = 3x + 1, we can find the point of intersection, which represents the solution to the system of equations.

The point of intersection is the solution to the system of equations.

Possible outcomes are Head, Middle, and Tail.

Since all outcomes are equally likely, the probability of each event is same, therefore

P(Head) = P(Middle) = P(Tail)

= 1/3

P(B|A) is 1/3

P(C|A) is 2/3

A and B are independent

A and C are not independent

Part a

Finding the sample space, S

S = { (HH), (HM), (HT), (MH), (MM), (MT), (TH), (TM), (TT) }

Part b

Finding  P(B|A) and P(C|A):

n(B and A) = no. of outcomes in which the first toss is Middle and second toss is Tail = 1

n(A) = Total no. of events in which the first toss is Middle = 3

Therefore, P(B|A) = 1/3

n(C and A) = no. of outcomes in which the first toss is Middle and total no. of heads is zero = 2

n(A) = Total no. of events in which the first toss is Middle = 3

Therefore, P(C|A) = 2/3

Part c

Finding if A and B are independent, or if A and C are independent

Two events A and B are said to be independent when the occurrence of one event does not affect the occurrence of the other event and vice versa. In case of independent events,

P(A) = P(first toss is Middle) = 3/9 =1/3

P(B) = P(second toss is Tail) = 3/9 = 1/3

P(A and B) = P(first toss is Middle and second toss is Tail) = 1/9

P(A)*P(B) = (1/3)*(1/3)

= 1/9 = P(A and B)

Hence, we can say that events A and B are independent.

For A and C, we have,

P(A) = P(first toss is Middle) = 3/9

P(C) = P(total no. of Heads is 0) = 4/9

P(A and C) = P(first toss is Middle and total no. of heads is 0) = 2/9

P(A)*P(C) = (3/9)*(4/9)

= 4/27 P(A and C)

Hence, events A and C are not independent.

The question was incomplete, the complete question is:

The population changes to 12.5% in 5 years.

Given the logistic model f(x)=800/1+19e^−0.402x, he initial value is 40

You should recall that Logistic regression is a statistical model that models the probability of an event taking place by having the log-odds for the event be a linear combination of one or more independent variables

The given question states thus: f(x)=800/1+19e^−0.402x, what is the initial value?

The initial value is the value when the value of x = 0

This implies that f(x) = (800)/ [1 + 19e⁻⁰°⁴⁰²ˣ

Simplifying this we have

f(x) = (800) / (1 + 19e⁰)

⇒ (800)  1 + 19

Simplifying to have

f(x) = 800/20

Dividing 800/20 to get 40

f(x) = 40

In conclusion, the initial value of f(x)=800/1+19e^−0.402x is 40

A type I error means that the hypothesis test has failed to detect a real treatment effect. This statement is incorrect. A type I error is also known as a false positive error, and it occurs when the null hypothesis is rejected even when it is true.

A type I error occurs when a hypothesis test rejects a null hypothesis when it is actually true. It's also referred to as a "false positive" because the test indicated that there is a difference when there isn't one.

The level of significance (also known as alpha) is frequently utilized to calculate the likelihood of making a type I error. It's usually set at 0.05 or 0.01, which means there's a 5% or 1% chance of making a type I error if the null hypothesis is true.

Answer:

0 < x < 28

Step-by-step explanation:

The triangle inequality theorem states that the sum of any two sides of the triangle should be greater than the third side.

Therefore,

All the possible values of x are 26 < x < 28.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

So a triangle has three sides.

We have the triangle inequality theorem which states that,

The length of any side of the triangle is always less than the sum of the other two sides.

And the range of the possible measure of the third side is the sum and the difference of the other two sides.

So x < 27 + 1 = 28

and,

x > 27 - 1 = 26

So 26 < x < 28

Hence the measures of third side is 26 < x < 28.

Answer:

\(y = -8x + 3\)

Step-by-step explanation:

When lines are parallel to one another, their slopes are the same.  But they have different y-intercepts. To explain further, slope is the angle of measure of a line from a horizontal standpoint and knowing that parallel angles must have the same angle, it can be concluded that parallel lines would have the same slope or in other words, an equal slope.

Now solving, use algebraic concepts:

11 = -8(-1) +b    (Now solve for b)

11 = 8 + b     (Subtract 8 from both sides) (Use the "Right" to "Left")

-8   -8

3 = b  (Switch terms)

b = 3

The rocket will land at the point of 124.43 meters from the starting point (option a).

To solve this problem, we'll need to use the equation provided in the problem, which gives the width of the rocket as a function of the horizontal distance from the starting point on the roof. In other words, we have a mathematical function that describes the shape of the rocket's flight path.

The function is given by:

f(x) = -0.05x² + 6.2x + 2.7

where x is the horizontal distance from the starting point, and f(x) gives the height of the rocket above the ground at that distance.

Now, we need to find out where the rocket lands, which means we need to find the horizontal distance at which its height is zero (i.e., when it hits the ground). In other words, we need to find the x-value that makes f(x) = 0.

To do this, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = -0.05, b = 6.2, and c = 2.7 (from the equation f(x) = -0.05x² + 6.2x + 2.7).

Plugging these values into the formula, we get:

x = (-6.2 ± √(6.2² - 4(-0.05)(2.7))) / 2(-0.05)

Simplifying this, we get:

x = (-6.2 ± √(38.44)) / -0.1

x ≈ -3.31 or x ≈ 124.43

Since we're only interested in the positive solution (the rocket can't travel a negative distance), we can round our answer to the nearest hundredth meter:

x ≈ 124.43 meters

Hence the correct option is (a).

The given proof demonstrates that the measure of angle RST is equal to the difference between the measures of angles MTQR and MTR. It begins by establishing the tangency of RS and TS to arc v at points R and T, respectively.

Using the Angle Addition Postulate and substitution, the proof shows that angles MZRSV and MZTSV are both equal to x. By substituting the values for MTR and MTQR and applying the Angle Addition Postulate, it is concluded that the measure of angle RST is equal to the difference between the measures of angles MTQR and MTR.

The given proof utilizes various geometric properties and postulates to establish the relationship between angles RST, MTQR, and MTR. It starts by stating that RS and TS are tangent to arc v at points R and T, respectively. Then, it applies the Angle Addition Postulate to establish that the sum of angles MZRSV and RSV is equal to 90 degrees, and the sum of angles MZTSV and TSV is also equal to 90 degrees. These steps are proven using substitution and the properties of tangent lines.

Next, the proof substitutes the given information that MTR equals 180 degrees minus 2x. By using the Angle Addition Postulate again, it determines that MTQR is equal to 180 degrees plus 2x. Substituting these values into the equation, the proof concludes that the measure of angle RST is equal to the difference between the measures of angles MTQR and MTR, which is (MTQR - MTR). This conclusion is reached by applying the Substitution and Addition Property of Equality, as well as the Multiplication Property.    

In summary, the proof provides a logical and step-by-step demonstration of how the measure of angle RST can be derived as the difference between the measures of angles MTQR and MTR, based on the given information about the tangency of RS and TS to arc v.
