Answers

Answer 1

The value of the probability P(A u B') is 0.8218

How to determine the probability?

The given parameters are

P(A) = 0.67

P(B) = 0.54

P(A u B) = 0.89

From the above parameters, we have

P(B') = 1 - P(B)

P(B') = 1 - 0.54

P(B') = 0.46

So, we have

P(A u B') = P(A) + P(B') - [P(A) * P(B')]

This gives

P(A u B') = 0.67 + 0.46 - (0.67 * 0.46)

Evaluate

P(A u B') = 0.8218

Hence, the value of the probability P(A u B') is 0.8218

If the slope of a line and a point on the line are​ known, the equation of the line can be found using the​ slope-intercept form, y=mx+b. To do​ so, substitute the value of the slope and the values of x and y using the coordinates of the given​ point, then determine the value of b.
Using the above​ technique, find the equation of the line containing the points ​(​-2,8) and (4,-1)

The equation of the line containing the points ​(​-2,8) and (4,-1) is:

y = -3x/2 + 5

Given data

points ​(​-2,8) and (4,-1)

How to find the equation of the line with the points ​(​-2,8) and (4,-1)

From the equation of the straight line y = mx + c

The slope of the line m is solved by

m = ( y2 - y1 ) / ( x2 - x1 )

m = ( -1 - 8 ) / ( 4 - -2 )

m = (-9 ) / ( 6 )

m = -3/2

using the point ( 4, -1 ) we find the intercept as

y = mx + c

-1 = -3/2 * 4 + c

-1 = -3 * 2 + c

-1 = -6 + c

-1 + 6 = c

c = 5

Substituting the values of m = -3/2 and c = 5 to the equation y = mx + c gives the equation of the line. This is done as follows

y = mx + c

y = -3/2 * x + 5

Given the piece-wise function, the output value of f(7) is 42.

What is the output value of f(7) in the given piece-wise function?

A piece-wise function is simply a function built from pieces of different functions over different intervals

Answers

8000 is the population of village in 1970.

Given that:

The linear equation of the population, P, of a village t years after it was founded in 1970, is given by

P(t) = 8000 + 600t.

To find:

What is the population in 1970 ?

So, according the question

We have,

The population of a village after t years from 1970 in a form of linear equation is,

 P(t) = 8000 + 600t.

This linear equation was founded in 1970, so t years will be counted after 1970. If we need to find the population of a village in 1971, we can use t = 1971 - 1970, which is one year. But here we have to find the population of a village in 1970, so the value of time is 0.

Now, putting the value of t.

We will be get,

 P(t) = 8000 + 600t.

 P(0) = 8000 + 600 × 0.

 P = 8000

The angels of parallelogram is 162, 18, 162 and 18.

How to find the measures of the other three angles in the parallelogram?

given that A parallelogram has one angle that measures 18° means one angle is 18°

we know that

A special variety of quadrilateral called a parallelogram has two sets of opposite sides that are parallel and equal.

The sum of all the angels of parallelogram is equal to 360°

so, the other means second angle of parallelogram is 18°

Let us assume the 3rd be x.

then the 4th also be x, because the opposite sides are equal.

now sum of all angles is 360°

then x + 18 + x + 18 = 360

2x + 36 = 360

2x = 360 - 36

x = 162.

so the 3rd and 4th angles are 162°.

The measures of angle ACB and angle ABC are 40° and 63° respectively

How to determine the value

From the information given, we have that angle DAB is on a straight line

But angle D is 103°

Remember that angles on a straight line sum up to 180°

Then,

103° + Angle A = 180°

Angle A = 180 - 103

Angle A = 77°

It is important to note that sum of angles in a triangle is 180°

angle ACB + angle ABC + angle CAB = 180°

Where;

angle ACB = 3x - 14angle ABC = 3x + 9angle CAB = 77°

Substitute into the formula

3x - 14 + 3x + 9 + 77 = 180

collect like terms

3x + 3x = 180 - 72

6x = 108

Make 'x' the subject

x = 108/6

x = 18

But;

Angle ACB = 3x - 14 = 3(18) - 14 = 54 - 14 = 40°

Angle ABC = 3x + 9 = 3(14) + 9 = 54 + 9 = 63°

Thus, the measures of angle ACB and angle ABC are 40° and 63° respectively.

The difference two positive integer is 3. If the smaller is added to the square of the larger the sun is 417 find the integers

Answers

Answer:

[tex]17[/tex] and [tex]20[/tex].

Step-by-step explanation:

Let [tex]x[/tex] denote the larger one of the two positive integers ([tex]x > 0[/tex].) The smaller integer would be [tex](x - 3)[/tex]. The square of the larger integer would be [tex]x^{2}[/tex].

The sum of the smaller integer and the square of the larger integer is [tex](x^{2} + (x - 3))[/tex]. If this sum is equal to [tex]417[/tex], then:

[tex]x^{2} + x - 3 = 417[/tex].

[tex]x^{2} + x - 420 = 0[/tex].

Solve this quadratic equation for [tex]x[/tex] through factorization. Since [tex]420 = 21 \times 20[/tex]:

[tex]x^{2} + x - (21 \times 20) = 0[/tex].

[tex]x^{2} + 21\, x - 20\, x + (21)\, (-20) = 0[/tex].

[tex](x + 21)\, (x - 20) = 0[/tex].

Thus, either [tex]x = 20[/tex] or [tex]x = (-21)[/tex] by the Factor Theorem. However, since [tex]x > 0[/tex] (the two integers are both positive,) only [tex]x = 20[/tex] is a valid solution.

Hence, the larger one of the two integers would be [tex]20[/tex]. The smaller one of the two integers would be [tex](x - 3) = (20 - 3) = 17[/tex].

How to dilate a polygon set on Cartesian plane by rigid transformation

In this problem we find a polygon generated by four vertices, whose locations are shown in the picture and whose image must be found by using rigid transformation formulas.

Rigid transformations are transformations such that the form of a geometric loci is conserved, dilations are an example of rigid transformation. The general formula of a dilation is described below:

P'(x, y) = O(x, y) + k · [P(x, y) - O(x, y)]  

Where:

O(x, y) - Center of dilationP(x, y) - Original pointP'(x, y) - Resulting pointk - Dilation factor

If we know that O(x, y) = (- 2, 4), k = 2 / 3, T(x, y) = (7, 1), U(x, y) = (4, 4), V(x, y) = (1, 13) and W(x, y) = (- 2, 4), then the coordinates of the polygon are now determined:

T'(x, y) = (- 2, 4) + (2 / 3) · [(7, 1) - (- 2, 4)]

T'(x, y) = (- 2, 4) + (2 / 3) · (9, - 3)

T'(x, y) = (- 2, 4) + (6, - 2)

T'(x, y) = (4, 2)

U'(x, y) = (- 2, 4) + (2 / 3) · [(4, 4) - (- 2, 4)]

U'(x, y) = (- 2, 4) + (2 / 3) · (6, 0)

U'(x, y) = (- 2, 4) + (4, 0)

U'(x, y) = (2, 4)

V'(x, y) = (- 2, 4) + (2 / 3) · [(1, 13) - (- 2, 4)]

V'(x, y) = (- 2, 4) + (2 / 3) · (3, 9)

The measurement of the angle indicated for each trapezoid is m<B equal to 70.

What is trapezoid shape?

A trapezoid, also known as a trapezium, is a flat closed shape having 4 straight sides, with one pair of parallel sides. The parallel sides of a trapezium are known as the bases, and its non-parallel sides are called legs.

Given :

In the trapezoid angle

m<B=11x+15

m<C=19x+15

According to the question,

The trapezoid is a quadrilateral.

The 4 angles of a quadrilateral all equal to 360 degrees.

The angles between parallel lines add up to 180degree due to adjacent angle.

So,

The equation is

m<B+m<C=180

11x+15+19x+15=180

30x+30=180

Subtract 30 from both sides we get,

30x=150

Divide by 30 on both sides we get,

x=5

∴m<B=11x+15=11*5+15

m<B=70

m<C=19x+15=19*5+15

m<C=110

Deposit amount is an amount of money paid into an account.

From the given information:

Then

Amount before deposit the money = $80

Amount deposited = $100

Then

Total amount after deposited = $100+80

Total amount after deposited = $180

Then

Amount After withdrawing = $180 - 100

Amount after withdrawing = $80

How much pure acid should be mixed with 3 gallons of a 20% solution in order to get a 40% acid solution?

I know how to set up the problem but I just can't seem to get the right answer. I know the formula is:
x+%1(gallons)=%2(x+gallons)
Help Please!

Answers

One gallon of pure acid must be added to get a 40% acid solution.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

Given that

3 gallons of a 40% acid solution means you have (20%)×(3) = 0.6 gallons of acid already.

Let x of gallons of pure acid be added to get a 40% acid solution.

⇒ (0.6 +x)/(3+x) = 40%

⇒ (0.6 +x)/(3+x) = 4/10

Cross multiply, we get

⇒ 10(0.6+x) = 4(3+x)

⇒ 6 + 10x = 12 + 4x

⇒ 10x - 4x = 12 - 6

⇒ 6x = 6

⇒ x = 1

Therefore, one gallon of pure acid must be added to get a 40% acid solution.
