Answer:

False

Step-by-step explanation:

A trapezoid is one special type of quadrilateral.

The speciality is one pair of opposite sides would be parallel.

The trapezium may or may not have the non parallel sides equal.  If they are equal it is called isosceles trapezium

Here when we consider a trapezium, the median is the line joining the mid points of the non parallel sides.

Since trapezium is narrow on one side of the median and wider on the other side of the median, this cannot divide the trapezium into two symmetrical shapes.

Hence A trapezoid cannot have symmetry with respect to the median of the trapezoid.

Mariana [72]

Answer:

  1. <em> 15</em>
  2. <em> 42,250</em>

Step-by-step explanation:

The given function is,

P=40000+300x-10x^2

where,

P = the total production of apples,

x = the number of trees added.

As the quadratic function has a negative leading coefficient, so it will open downward and at the vertex the value of function is maximum.

The vertex will be at \left(-\dfrac{b}{2a},-f\left(\dfrac{b}{2a}\right )\right)

The value of the function will be maximum at,

x=-\dfrac{b}{2a}

Putting the values,

x=-\dfrac{300}{2\times (-10)}=\dfrac{300}{2\times 10}=\dfrac{300}{20}=15

So at x=15 or for 15 number of trees the production will be ,maximum.

Putting x=15 in f(x) will yield the maximum production of apples.

P=40000+300(15)-10(15)^2=42,250

S_A_V [24]

Answer:

C

Step-by-step explanation:

5 + 6 + 4 = 15

Small - 5/15 = 1/3

Large - 4/15 = 4/15

The probability that he grabs a Large-sized shirt would be 4/15, which is around 26.7%. After that, he will grab a Small-sized shirt, which would have a probability of 33.33%. After combining the two, the only answer choice that could possibly make any sense is C. (using the process of elimination.)
