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

The ribbon was 3 1/4 inches wide and had an area of 19 1/2 square inches. What is the length of the ribbon? Please Help Will Giv
miv72 [106K]
Hello!

The formula for finding area is l × w

If the area is 19 ½ inches and it was 3 ¼ inches wide, then the length will be 19 ½ ÷ 3 ¼ (Area ÷ Width)

19  \frac{1}{2} \div 3  \frac{1}{4}

Change both to improper fraction

19  \frac{1}{2} =   \frac{39}{2}

3  \frac{1}{4} =  \frac{13}{4}

\frac{39}{2} \div  \frac{13}{4}

Keep 39/2
Change ÷ to ×
Flip 13/4 = 4/13

\frac{39}{2} \times  \frac{4}{13} =  \frac{156}{26} = 6

\framebox {The length of the ribbon is 6 inches}

the contractor demands a working temperature of 82 degrees Fahrenheit. what is the equivalent temperature in degrees Celsius
stiks02 [169]

Answer:

27.8 Celsius

Step-by-step explanation:

The equation to convert Fahrenheit and Celsius is:

F = (9/5)C + 32

82 = (9/5)C + 32 -- subtract 32 from both sides

50 = (9/5)C -- multiply both sides by 5

250 = 9C -- divide by 9

27.777 = C

round up to 27.8 C
