Mariya is solving the quadratic equation by completing the square.

DerKrebs [107]

Answer:

A=4

Step-by-step explanation:

Mariya was solving:

4x2-20x+3=0

4x2-20x=-3

A(x2-5x)=-3

At this point, we can know that 4*x2=4x2 and 4*5x=20x, son A=4

The annual 2-mile fun-run is a traditional fund-raising event to support local arts and sciences activities. It is known that th

victus00 [196]

Answer: 0.0228

Step-by-step explanation:

Given : The mean and the standard deviation of finish times (in minutes) for this event are respectively as :-

$\mu=30\\\\\sigma=5.5$

If the distribution of finish times is approximately bell-shaped and symmetric, then it must be normally distributed.

Let X be the random variable that represents the finish times for this event.

z score : $z=\dfrac{x-\mu}{\sigma}$

$z=\dfrac{19-30}{5.5}=-2$

Now, the probability of runners who finish in under 19 minutes by using standard normal distribution table :-

$P(X$

Hence, the approximate proportion of runners who finish in under 19 minutes = 0.0228

Mhanifa can you please help this is due asap

sleet_krkn [62]

Answer:

<h3>Question 1 </h3>

<em>Adjacent angles are supplementary, opposite angles are equal</em>

62 + 5x + 3 = 180
5x = 180 - 65
5x = 115
x = 23

62 = 3y + 2
3y = 60
y = 20

<h3>Question 2</h3>

<em>Diagonals bisect each other</em>

4x = 3x + 7
x = 7

6y = 2y + 16
4y = 16
y = 4

Correct choice is A

Describe how a point on a graph is related to a table and an equation that represent the same relationship.

castortr0y [4]

Answer:

because everything is relative to each other.

Step-by-step explanation: Graphing ordered pairs is only the beginning of the story. Once you know how to place points on a grid, you can use them to make sense of all kinds of mathematical relationships. A linear relationship is a relationship between variables such that when plotted on a coordinate plane, the points lie on a line. Let’s start by looking at a series of points in Quadrant I on the coordinate plane. Look at the five ordered pairs (and their x– and y-coordinates) below.
