The area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.

A trapezium is a quadrilateral having two opposite sides parallel.

The area of a trapezium is equal to;

[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}[/tex]

The trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis.

The vertices are at (0,10), (10,10),(5,5) and (0,5)

You need to find the area of the rectangle (0,10) (10,5) (0,5) and (5,5)

The lengths are 5, 5,5,5.

The area of the legs is = 5 × 5 =25

The area is;

[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}\\\\Area =\dfrac{1}{2} \times 5 \times 5\\\\Area =12.5[/tex]

And the right triangle (10,5),(5,5), and (10,10) the right angle is at (10,5)

the two legs are lengths 5 and 5

so together they are 25 +12.5=37.5 square units.

Hence, the area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.

The quadrilateral that is described with the given properties is known as; Rhombus

A quadrilateral is defined as a closed shape and a type of polygon that has four sides, four vertices and four angles.

Now, we are told that at least  at least two pairs of consecutive sides are congruent, diagonals are perpendicular to one another.

The only quadrilaterals that fit into thus definition are square and rhombus.

Now, we are told that the quadrilateral cannot be inscribed in a circle. A square can be inscribed in a circle but not a rhombus and as such we can say that the quadrilateral with the given properties is a rhombus,

Step-by-step explanation:

To solve the inequality:

4x + 8 ≥ -4

4x ≥ -12

x ≥ -3

If this is what you did then I'm not sure how you ended up getting x ≤ -3. You're not dividing by a negative number so the sign never switches.

Hope this helps

Step-by-step explanation:

−4≤4x+8

Subtraction property of inequality with the value 8.

-12≤4x

Division property of inequality with the value of 4.
The reason the sign stays as less than or greater to is because the sign only switches when the DIVISOR is negative, not the dividend.

According to the Empirical Rule (68-95-99.7% Rule), approximately 68% percent of the values will be between 75 and 85.

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

Here, we had  where mean of distribution of X is [tex]\mu[/tex] and standard deviation from mean of distribution of X is [tex]\sigma[/tex].

A distribution of scores on an aptitude test is Normally distributed with a mean of 80 and a standard deviation of 5.

[tex]\mu=80\\\sigma=5[/tex]

The percentage for the interval of values between 75 and 85 has to be found out. From the 68%, the interval is,

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(80 - 5 < X < 80+ 5) = 68\%\\P(75 < X < 85) = 68\%[/tex]

Thus, according to the Empirical Rule (68-95-99.7% Rule), approximately 68% percent of the values will be between 75 and 85.

Answer:

false

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

First, consider (0,2) and (8,2).  The y-value is the same for both points.  x ranges from 0 to 8, so the length of this horizontal side of the triangle is (8-0), or 8.

Again, this horiz. side has a y-value of 2.

The third point is (4,-3).  Therefore the vertical distance from the horizontal line to the third point is 2 - (-3), or 5.

Thus, the "base" of the triangle is 8 and the "height" is 5.

The area is  A = (bh)/2.  Substitute the values 8 and 5.  Simplify your result.  Answer:  20 square units.
