There were 2,626,418 deaths in 2014 according to the CDC. 614,348 of these deaths were caused by diseases of the heart and 136,0
Alex777 [14]

Answer:

= 0.714 (in decimal fraction)

The probability that the death in 2014 was not caused by heart diseases or Unintentional Injuries = 0.714

= 0.714

Step-by-step explanation:

Let's interpret the question our way ti solve it .

Total deaths in 2014:

2626418

Death caused by Heart Diseases:

614348

Death caused by Unintentional Injuries:

750401

Therefore, we can deduced that, the number of death not caused by Heart Diseases or Unintentional Injuries = Total deaths in 2014 minus sum of the recorded death.

= 2626418 - ( 614348 + 136053)

= 2626418 - 750401

= 1876017.

Now, the probability that there were death in 2014 is 1 (one)

To find the probability that death we're not caused by heart diseases or Unintentional Injuries:

= 1 - Pr (Death Caused by heart diseases) + Pr (Death causes by Unintentional Injuries)

= 1 - (0.234 + 0.052)

= 1 - 0.286

= 0.714

To Check:

= 1876017 / 2626418

Divide to the lowest term

=0.714

2X to the second power minus 4X equals three in standard form
Elena-2011 [213]

Answer:

2x^2-4x=3

standard form of a quadratic equation =ax^2+bx+y=0

so you would bring the 3 over to the other side making the solution 2x^2-4x-3=0

Serga [27]
Its line 1

if we expand the second and third expressions they come back to the first.

The last one is called the vertex form of a parabola
