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.

Find the limit, if it exists (picture below)

valentinak56 [21]

Answer:

c. $\frac{1}{2 \sqrt{7} }$

Step-by-step explanation:

When plugging in zero into the given equation:

$\lim_{x \rightarrow 0} \frac{\sqrt{x + 7} - \sqrt{7} }{x} = \frac{0}{0}$

Answer is in indeterminate form = use L'Hospital's Rule:

(Derivative of the top / Derivative of the bottom)

$\lim_{x \rightarrow 0} \frac{ \frac{1}{2} (x + 7)^{ \frac{-1}{2}} - 0 }{1}$

Rearranged equation:

$\lim_{x \rightarrow 0} \frac{1}{2 \sqrt{x + 7} }$

Plug zero back into equation:

$\lim_{x \rightarrow 0} \frac{1}{2 \sqrt{x + 7} } = \frac{1}{2 \sqrt{0 + 7} } = \frac{1}{2 \sqrt{7} }$

Answer:

$\lim_{x \rightarrow 0} \frac{\sqrt{x + 7} - \sqrt{7} }{x} = \frac{1}{2 \sqrt{7} }$

If F(x)=9x which of the following is the inverse of F(x)

user100 [1]

Answer:

Inverse of F(x)=9x = 1/9x

Step-by-step explanation:

If F(x)=9x

which of the following is the inverse of F(x)

When talking about inverse of a function, we are talking about reversal. Therefore, an inverse function is the inverse of another function. In order to get the inverse of a particular function, we reverse the denominator to become the numerator and the numerator to become the denominator.

So for the function,

F(x)=9x, the numerator is 9x and the denominator is 1

Reversing the numerator and denominator, .

Inverse of F(x)=9x = 1/9x
