The length of the mid-segment of the given trapezoid will be 8.5.

A quadrilateral is a geometrical 2d shape in which there are four sides and each side is connected and makes a close polygon.

In other meaning, a quadrilateral is a kind of polygon in which four sides for example rectangle, square, and parallelogram are quadrilateral.

As per the given vertices,

I(-3, -5), J(8, -5), K(3, -9), and L(-3, -9)

The trapezoid has been plotted below.

The length of LK = 3 - (-3) = 6 units.

Length IJ = 8 - (-3) = 11 units

The length of midsegment x = (11 + 6)/2 = 17/2 = 8.5

A  conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.

The likelihood that any two events will occur is equal to the sum of the probabilities of each event separately, less the probability that the two occurrences will meet. However, if two occurrences are incompatible with one another, then there is a zero probability of the two events intersecting, therefore the likelihood that either one or the other will occur is equal to the sum of the two individual probabilities.

To calculate conditional probability, use the following formula:

p( b | a ) = p( a ∩ b )/ p(a)

It is known that if two events A and B are independent, then p(a ∩ b) = p (a) . p(b)

So, p(b | a) = [p (a) . p(b)]/p(a) = p(b)

Thus, it is concluded that a conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

Answer:

Below

Step-by-step explanation:

10 % OFF means you pay 90% of price

x = original price

Store A :   5% off    means   price is .95x

                    then another 10% off would mean  .9 * (.95x)

                        then another 10% off would mean  .9 * ( .9 *(.95x)

                               this equals .7695 x

Store B 25% off means you pay 75%  

  price is then .75x

price of      .75x at store B is < than .7695 x at store A  

    so B has greater discount

Answer:

Step-by-step explanation: To compare the discounts offered by Store A and Store B, we need to calculate the final price of the item after all discounts have been applied.

For Store A, the successive discounts of 5%, 10%, and 10% can be applied as follows:

The initial price of the item is reduced by 5%, resulting in a price of 0.95 * Price.

The price from step 1 is reduced by an additional 10%, resulting in a price of 0.9 * (0.95 * Price) = 0.855 * Price.

The price from step 2 is reduced by an additional 10%, resulting in a price of 0.9 * (0.855 * Price) = 0.7695 * Price.

For Store B, the single discount of 25% can be applied as follows:

The initial price of the item is reduced by 25%, resulting in a price of 0.75 * Price.

Comparing the final prices of the item at Store A and Store B, we can see that Store B offers a greater discount. The final price of the item at Store A is 0.7695 * Price, while the final price at Store B is 0.75 * Price. Since 0.75 is less than 0.7695, the final price at Store B is lower.

Therefore, Store B offers a greater discount on the item.

Option D is correct the answer. The average rate of change over the interval 1 < x < 5 is greater than the average rate of change over the same interval for the function g(x) = 1. 8x2 is k(x) = 2x^2

The average rate of change:

Given a function y, the average rate of change S of y=f(x)  in an interval (xs,xf) will be given by the following equation:

[tex]S=\frac{f(xf)-f(xo)}{xf-xo}[/tex]

In this problem, we have that:

Interval (1,5), so xf=5,xo=1

Then

[tex]S=\frac{f(5)-f(1)}{4}[/tex]

All options are compared to g(x).

[tex]g(x)=1.8x^{2}[/tex]

g(5) = 1.8*(5)^2 = 45

g(1) = 1.8*(1)^2 = 1.8

[tex]S=\frac{45-1.8}{4} =10.8[/tex]

A.=f(x) = x^2

f(5) = 5^2 = 25

f(1) = 1^2 = 1

[tex]S=\frac{25-1}{4} =6.25[/tex]

Smaller than 10.8, so this is not the answer.

B.=g(x) = 1.2x^2

g(5) = 1.2*(5)^2 = 30

g(1) = 1.2*(1)^2 = 1.2

[tex]S=\frac{30-1.2}{4} =7.2[/tex]

Smaller than 10.8, so this is not the answer.

C.=h(x) = 1.5x^2

h(5) = 1.5*(5)^2 = 37.5

h(1) = 1.5*(1)^2 = 1.5

[tex]S=\frac{37.5-1.5}{4}= 9[/tex]

Smaller than 10.8, so this is not the answer.

D.=k(x) = 2x^2

k(5) = 2*(5)^2 = 50

k(1) = 2*(1)^2 = 2

[tex]S=\frac{50-2}{4} =12[/tex]

Answer:

The x-axis interval of 39 to 65 has the smallest rate of change.

Step-by-step explanation:

See the attached worksheet.  The interval of x that results in the least change in y can be visually seen by plotting the points and drawing a curve.  The curve begins to flatten as x increases.  So the smallest rate of change is between the last two points, x = 39 to 65.

This can also be calculated by finding the change in y per a change in x.  The table in the graph confirms the earlier observation.  Dx and Dy represent the "delta," or difference, D,  between the x (Dx) and y(Dy) values.  The rate of change is calculated as Dy/Dx, or the change in y divided by the change in x.  The results confirm that the 39 to 65 segment is the smallest, at 0.15.

Answer: The y-intercept is 14

y=-5x+b

substitute the points of (3,-1) into the equation and solve for b

-1=-5(3)+b

-1=-15+b

b=14

The y-intercept is 14

The y-intercept of the line is 14.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = -5

The line passes through the point (3, -1).

The equation of the line is y = mx + c.

y = -5x + c

(3, -1) = (x, y)

Answer:

the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).

Step-by-step explanation:

Correctly me if im wrong. To rationalize the denominator of the fraction 1/(5^(1/2)-2), we can use the conjugate of the denominator. The conjugate of a+b is a-b, so the conjugate of 5^(1/2)-2 is 5^(1/2)+2. We can then multiply the numerator and denominator of the fraction by the conjugate to obtain:

1/(5^(1/2)-2) * (5^(1/2)+2)/(5^(1/2)+2)

= (1*(5^(1/2)+2)) / ((5^(1/2)-2)*(5^(1/2)+2))

= (5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)

Notice that we can further simplify this expression by substituting 5^(1/2) with x and expanding the denominator:

(5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)

= (x+2) / (x^2 - 2x - 4)

= (x+2) / (x-2)(x+2)

The denominator of this expression can be further simplified by factoring out x-2, which gives us:

(x+2) / (x-2)(x+2)

= (x+2) / (x-2)(x-2 + 4)

= (x+2) / (x-2)(x^2 - 2x + 4 - 4)

= (x+2) / (x-2)(x^2 - 2x)

= (x+2) / (x-2)((x-1)(x+1))
Finally, we can use the fact that x-1 and x+1 are factors of x^2-2x, which means that we can factor out x-1 and x+1 from the denominator to obtain the fully simplified expression:
(x+2) / (x-2)(x^2 - 2x)

= (x+2) / (x-2)(x-1)(x+1)

= (x+2) / ((x-2)(x-1)(x+1))

Therefore, the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).
