A relationship between two quantities that is typically stated as the product of their respective quotients.

The ratio of red to blue marbles, or 6:4, is, for instance, 6:4 if a box contains six red and four blue marbles. Decimal or percentage expressions of ratios are also possible. This implies that there would be 10 children for every 16 adults.

The number of children there would be for 40 adults can be calculated by dividing 40 by 16, then multiplying the result by 10.

40/16=2.5

2.5×10=25

25 kids.

Given the relation R = {(6,4), (8,-1), (x,7), (-3,-6)}. Which of the following values for x will make relation R a function

(a) 8

(b) 6

(c) -3

(d) 1

CONCEPT TO BE IMPLEMENTED

FUNCTION

Let A and B are two non empty sets. A Mapping (function ) f from A to B is a rule that assigns to each element x of A a definite element y in B

EVALUATION

Here the given relation

R = {(6,4), (8,-1), (x,7), (-3,-6)}

Take A = {6,8,x,-3}

B={-6, -1, 4,7}

In order to satisfy all requirement for R to be mapping is R will have to assign to each element x of A a definite element y in B

Since R has mapped 6, 8, -3 already

So R can not map 6, 8, - 3 again

So R can not be any of 6, 8, - 3

.'. X = = 1

Answer:

5y + 4; y = -4/5

Step-by-step explanation:

combine like terms

add 2y+3y together, and -1+5

5y+4=0

-4        -4

5y= -4

/5      /5

y= -4/5

Answer:

0.156

Step-by-step explanation:

P(A & B) = P(A) * P(B)

P(Yankess score less than 5 and lose) = P(score less than 5) * P(lose)

0.39 * 0.4 = 0.156

Assuming that the scores on the first exam are a representation for the ones in the second exam, we will see that the probabilities are:

First we want to get the probability that a randomly selected student gets better than a C on the second test.

We assume the percentages for the first test can be applied for the second, so, the ones that got better than a C on the first exam are:

A: 12%

B: 28%

Then the probability is:

P( more than a C) = 12% + 28% = 40% (or 0.40 in actual probability notation)

b) Now we want to find the probability of fail.

The percentage that failed the first test is:

100% - 12% - 28% - 41% - 11% = 8%

So 8% of the students failed the first exam, this means that the probability that a randomly selected student fails the second exam is:

P = 8% or 0.8 in decimal notation.

C) 12% of the students tgot an A, so the probability that a randomly selected student does not get an A is:

P = 100% - 12%  =88%

or 0.88 in decimal notation.

yes,  the square box song big enough to fit the pizza inside.

what is square?

A square is a regular quadrilateral , which means that it has four equal sides and four equal angles.

we have that,

the diameter of the pizza is

D = 10 1/3in

the wide of the square box is

b=10.38in

we know that  

for the pizza to fit inside the box ,it must be fulfilled that

D ≤ b

convert 10.38 in to fraction number

10.38 (100/100)= 1.038/100=519/50

convert 101/3 in to an improper fraction

10 1/3 = 10+3+1/3=31/3

multiply the diameter of the pizza by 50 both numerator and denominator =31+50/50+3= 1.550/150 in

multiply the wide of the box by 3 both numerator and denominator 1.550/150in ≤ 1.557 /150 in

Since we see that P is a point on the perpendicular bisector, l, of MN, we have proven the required PM = PN by the definition of reflection, we can conclude that point P is the image of itself , while point N is the image of M .

We are given :

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

Now, we want to prove the assertion that PM = PN

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

From the question, we can say that by the definition of reflection, we can conclude that point P is the image of itself , while point N is the image of M .

The perpendicular bisector, l is acting as a Line of symmetry which is also called axis of reflection.

Now, due to the fact that reflections preserve lengths in transformation,  it means that we have; PM = PN.

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

The slope of a line can be calculated using the formula:

where (x1,y1) are the coordinates of the first point and (x2,y2) are the coordinates of the second

Mathematically, we have the slope of the first as follows:

For the second line, we have it that:

When two lines are perpendicular, the product of their slopes is equal to -1

We have it that:

This shows that the two lines are not perpendicular

The number of gallons in 6 containers is 4

The statement is given as

A container has a capacity of 2/3 gallons

This means that

1 container = 2/3 gallons

Multiply both sides of the equation by 3/2

So, we have

3/2 * 1 container = 2/3 gallons * 3/2

Evaluate the products

So, we have

3/2 containers = 1 gallon

Multiply both sides by 4

So, we have

4 * 3/2 containers = 4 gallons
