The population of the country was 314 million. What is the empirical probability of death by stroke during a single year

Marat540 [252]

Answer:

Empirical probability of deaths cause by stroke=0.004086

Empirical probability of deaths cause by kidney disease =0.001436

Death rate due to stroke is 4 times the death rate due to kidney disease.

Step-by-step explanation:

Consider the table attached in figure

No. of deaths cause by stroke = 128300

No. of deaths caused due t kidney disease = 45100

Total population = 314 x 10⁵

Formula to calculate empirical probability:

$P(A)=\frac{No.\, of\,\, times\,\, event\,\, occurs}{Total\,\, population}\\$

Empirical probability of deaths cause by stroke:

$P(A)=\frac{128300}{314\times 10^5}\\\\P(A)=0.004086$

Percentage of deaths cause by stroke =0.4%

Empirical probability of deaths cause by kidney disease:

$P(B)=\frac{45100}{314\times 10^5}\\\\P(B)=0.001436$

Percentage of deaths cause by kidney disease =0.1%

Ratio between deaths caused to stoke to deaths caused by kidney disease is 4:1 which means death rate due to stroke is 4 times the death rate due to kidney disease.

The equation of a line is 4x−3y=−24 .

Ludmilka [50]

Answer:

x = - 6

Step-by-step explanation:

The x-intercept is when y =0, you are looking for a point (x, 0)

So you replace y = 0 in the equation

4x - 3y = - 24

4x - 3(0) = - 24

4x = - 24

x = - 6

For a certain horse race comma the odds in favor of a certain horse finishing in second placehorse race, the odds in favor of a

NikAS [45]

Answer:

0.33

Step-by-step explanation:

Let A denote an event. The odds of the horse finishing second is 33 to 67.

From the information, the total outcomes of event A is:

$Total \ Outcomes, A=Favorable +Unfavorable\\\\=33+67\\\\=100$

Hence, there are 100 total outcomes. The probability of the horse finishing second is calculated as:

$p=\frac{n(A_f)}{n(A_u)}\\\\\\=p=\frac{33}{100}\\\\=0.33$

Hence, the probability of finishing second is 0.33
