________ are numbers equally likely to be chosen from a large population of numbers.
ki77a [65]

A simple random sample are numbers equally likely to be chosen from a large population of numbers.

<h3>What is Population?</h3>

This is defined as the total number of people or variables present in an area over a given period of time.

Numbers are usually chosen at random from a large population for different reasons and are referred to as simple random sample because they have an equal probability of being chosen.

Find the measure of ∠C if ∠A = 3 2 x + 20 ∠B = 7 2 x + 20 ∠C = 5 2 x + 40 ∠D = 3 2 x + 10 A) 65° B) 76° C) 95° D) 115°
Rudiy27
The sum of the angles of a quadrilateral is 360°.
\left(\dfrac{3}{2}x+20\right)+\left(\dfrac{7}{2}x+20\right)+\left(\dfrac{5}{2}x+40\right)+\left(\dfrac{3}{2}x+10\right)=360\\\\9x+90=360\\\\x=\dfrac{270}{9}=30

Given that x=30, the measure of ∠C is
  ∠C = (5/2)×30 +40 = 115

The appropriate choice is ...
  D) 115°

Plzzzzz help will give brain and points!!! Explain why a quadratic equation with a positive discriminant has two real solutions,
NISA [10]

Answer:

The given equation is -2x^2 = -8x + 8

This can be rewritten as 2x^2 - 8x + 8 = 0

Here the value of a =2, b = -8 and c = 8

Discriminant = b^2 - 4ac

Now plug in the above values in the discriminant, we get

= (-8)^2 - 4*2*8

= 64 - 64

= 0

Here the discriminant is 0, so we will get one real root.

The discriminant is equal to 0, which means the equation has one real number solution.

Hope this will helpful.

Thank you.
