Give a set of five integers, two positive and three negative, for which the mean, median, and mode are all -3
koban [17]
That's 5 integers...

Logic tells me that a number divided by 5 should be equal to -3. -15/5 is in fact equal to -3.

Let's find 5 integers (two positive and three negative) when added up together equal -15.

-14, -3, -3, 2, 3.

[(-14)+(-3)+(-3)+2+3]/5 = (-15)/5 = -3

Mean = -3

----------

Now let's put these numbers in order, from lowest to highest - then pick out the middle value...

-14, -3, [-3], 2, 3

The median turns out to be -3.

------------

Let's look at the numbers once again...

-14, -3, -3, 2, 3

It turns out that -3 appears the most, therefore -3 is the mode too.

Choose the correct word that completes each statement about inscribing a square in a circle.
Anna11 [10]

Answer:

1. Perpendicular

2. Isosceles

3. Never

Step-by-step explanation:

1. AC ⊥ BD because diameter of a square are perpendicular bisector of each other.

2. In Δ AOB , By using pythagoras : AB² = OA² + OB² .......( 1 )

In Δ COB , By using pythagoras : BC² = OC² + OB²  ..........( 2 )

But, OA = OC because both are radius of same circle

So, by using equations ( 1 ) and ( 2 ), We get AB = BC ≠ AC

⇒ ABC is a triangle having two equal sides so ABC is an isosceles triangle.

3. The side can never be equal to radius of circle because the side of the square will be chord for the circle and in a circle chord can never be equal to its radius

Which of the following is a solution to the equation x - 5/7 = -3/7
podryga [215]

Solve the equation:

          5              3
x  –  ——  =  –  ——
          7              7


           5
Add  ——  to both sides, so you get  x  isolated at the left-hand side:
           7

          5          5               3          5
x  –  ——  +  ——  =  –  ——  +  ——
          7           7              7           7

              3          5
x  =  –  ——  +  ——
              7           7


Now, add those fractions at the right-hand side of the equation:

          – 3 + 5
x  =  —————
               7

          2
x  =  ——     <———    this is the answer (first option:  2/7).
          7


I hope this helps. =)
