From the unique line postulate, we can draw unique line segment PM and as we are given that P is a point on the perpendicular bisector I of MN, the proof below has shown that using the definition of reflection, point P is the image of itself and point N is the image of point M

We are given :

Point P is a point on the perpendicular bisector, l, of MN.

Now, we want to prove that PM = PN

A Reflection in transformation can be defined as the transformation in which the figure is the mirror image of the other figure. This means that every point is a mirror reflection of itself .

With the aid of the definition of reflection, we can form the statement that point P is the image of itself , and point N is the image of M .

The line l which is the perpendicular bisector of MN acts as a Line of symmetry or axis of reflection.

Finally, when talking about transformations, it is common knowledge that reflections preserve length which means that the required proof PM = PN will hold true

Therefore, we will conclude that point N is the image of M .

Given,

The quadratic equation : x² + 8x + 7 = 0

We have to find the solutions for this quadratic equation using the quadratic formula.

Quadratic formula: [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

To find the values of the variables, divide the values of the result by the corresponding values of the main matrix.

We have:

Divide both sides by 7:

7y/7 = 21/7

y = 3

a) It is 0.1275 times more probability that fewer than five of them have type o negative blood.

b) The probability that less than five of them are type o negative blood types is 0.9933.

c) 0.2708 probability that there are no donors who have type O negative blood. It would not be odd to have no type o negative donors because this likelihood is higher than 0.05.

There are only two outcomes that can occur for any individual. Type o negative blood is either present or absent. Any other person has no effect on a person's likelihood of having type O negative blood. To answer this question, we thus employ the binomial probability distribution.

The probability of precisely x successes on n repeated trials is known as a binomial probability, and X can only have two possible outcomes.

P(X=x)= [tex]C_{n,x.P^{x}.(1-P)^{n-x} }[/tex]

Additionally, p is the probability that X will occur.

This means that P=0.07

This mean that n = 18

Either less than three have, or at least three do. The sum of the probabilities of these events is 1. So

P(X<3) + P(X≥3)=1

We want P(X≥3)

So,

P(X≥3) = 1-P(X<3)

In which

P(X< 3)= P(X = 0)+P(X = 1)+P(X = 2) = 0.2708 + 0.3669 +0.2348 = 0.8725

P(X≥3) = 1-P(X<3) = 1- 0.8725=0.1275

It's 0.1275 times more likely that fewer than five of them have type O negative blood.

P ( x < 5 )= P(X=0)+P(X=1)+P(X=3)+P(X=3)+P(X=4)

P(X=x)= [tex]C_{n,x.P^{x}.(1-P)^{n-x} }[/tex]

P(X=0)= [tex]C_{18,0(0.07)^{0}.(0.93)^{18} }= 0.2708[/tex]

The statement that are true about the equations − 3 ⁢ x − 8 = 19  and − 3 ⁢ x − 2 = 25 is that he equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.

From the first equation, we were given,  − 3 ⁢ x − 8 = 19

then if we add 6 to the both sides of the equation then we will have

− 3 ⁢ x − 8 + 6 = 19 + 6

Then if we perform the simplification on this equation we have,

− 3 ⁢ x − 2 = 25

The key to proving that two triangles are similar or congruent is to prove that three of either side lengths or angles are congrunet, similar or the same.

For the figure given, we have already been told that

Side AB = Side CD

Side AD = Side CB

Since the two triangles share a similar side in BD, we can complete this by saying

Side BD = Side BD

Side AB = Side CD

Side AD = Side CB

Side BD = Side BD

So, three of the sides of the triangles are equal or congruent.

Answer:

consistent system with equation [tex]y=6x+5[/tex]

Step-by-step explanation:

[tex]18x-3y=-15[/tex],   [tex]-6x+y=5[/tex]

To solve by substitution, we have to isolate a variable in one of the equations. I will isolate y in the second equation.

[tex]-6x+y=5[/tex]

+6x           +6x

[tex]y=6x+5[/tex]

Next, substitute this y value for y in the first equation:

[tex]18x-3y=-15[/tex]

[tex]18x-3(6x+5)=-15[/tex]

and distribute.

[tex]18x-18x-15=-15[/tex]

[tex]-15=-15[/tex]

We are left with an equality of constants. This means that the system of equations is actually just one equation, meaning it has an infinite number of solvable points (this is sometimes called consistent). And, its equation is just what we solved for in the first step:

Using the normal distribution, it is found that:

a) The sampling distribution is approximately normal, with mean 45 and standard deviation 4.

b) The answer is not dependent on the sample size, as the underlying distribution is normal.

c) 0.0001 = 0.01% probability that the average is less than half an hour.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For this problem, the parameters are given as follows:

[tex]\mu = 45, \sigma = 12, n = 9[/tex]

Hence the standard error of the approximately normal sampling distribution of sample means of size 9 is:

s = 12/sqrt(9) = 12/3 = 4.

As stated in the problem, the underlying distribution is normal, hence this is not dependent on the sample size.

For item c, the probability is the p-value of Z when X = 30, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (30 - 45)/4

Z = -3.75

Z = -3.75 has a p-value of 0.0001.

Answer:

Step-by-step explanation:

You want to classify a number of functions as even, odd, or neither.

An even function has a graph that is symmetrical about the y-axis. It has the characteristic that ...

  f(x) = f(-x)

A polynomial function will be an even function if it consists entirely of even-degree terms. (A constant is degree zero, hence even degree.) A rational function will be an even function if it can be reduced to the ratio of even functions.

An odd function has a graph that is symmetrical about the origin. It has the characteristic that ...

  f(x) = -f(-x)

A polynomial function will be an odd function if it consists entirely of odd-degree terms. A rational function will be an odd function if it reduces to the ratio of an even and an odd function.

A function is neither even nor odd if it does not have one of the symmetries mentioned above. A polynomial consisting of a mix of even- and odd-degree terms will be neither even nor odd.

This is the ratio of a "neither" function to an even function. It is neither even nor odd.

The ratio can be reduced to ...

  [tex]\dfrac{2x^4+8x^3}{x^3+4x^2}=\dfrac{2x^3(x+4)}{x^2(x+4)}=2x[/tex]

This consists only of an odd-degree term. It is an odd function.

This is the ratio of an odd function to an even function. It is an odd function.

This is the ratio of two even functions. It is an even function.

As in problem 2, the function can be reduced:

  [tex]\dfrac{2x^3+8x^2}{x^3+4x^2}=\dfrac{2(x^3+4x^2)}{x^3+4x^2}=2[/tex]

It is an even (degree 0) function.

This is the ratio of an even function to a "neither" function. It is neither even nor odd.

The function reduces to x+2, which is neither even nor odd.

This is the ratio of two even functions. It is an even function.

This is the ratio of two odd functions. It can be reduced to the ratio of two even functions, so it is an even function.

  [tex]\dfrac{4x^3+2x}{7x^5+3x^3}=\dfrac{2x(2x^2+1)}{x^3(7x^2+3)}=\dfrac{4x^2+2}{7x^4+3x^2}[/tex]

The unit rate of muffins per cup of almonds that the baker is for every 9 muffins, he uses 1 cup of almonds.

The unit rate is the ratio of a variable against another variable.

The unit rate explains the quantity relationship between the number of muffins produced and the cups of almonds used by the baker.

For this situation, a cup of almonds can make 9 muffins.

The total number of muffins made = 36

The total number of cups of almonds used = 4

The ratio of muffins to cups of almonds = 36:4 or 9:1

The unit rate of muffins per cup = 9 (36/4)
