Ages of patients (in years) in a clinic: 19, 8, 21, 19 (round to the nearest whole ).
Answers
So:
19+8+21+19=67
Divided by 4
67/4= 16.75
Rounded up you get 17

Answer:
= - 2.43%
Step-by-step explanation:
From the information given:
Since the variable (daily returns) is normally distributed, Then, using empirical rule at 95% confidence interval level, we have:
where;
The expected mean daily return
The standard deviation
Given that the 95% confidence interval is expected to be a maximum loss, then the probability is left-tailed which is 1.65 away from the average.
Thus the distribution of the lower boundary can be computed as:
=

What is Decimal Numbers?
Decimal number system is applicable for both integers as well as non integers. Decimal number include a whole number part and a decimal part separated using decimal point.
Fractions are the numbers which are part of a whole.
All decimal numbers can be written as fractions and fractions can be written in the form of decimal numbers.
The given number is 0.45.
0.45 can be written as .
can be expanded in various ways like (40 + 5)/100, (42 + 3)/100 and so on.
can be written in one of the form as
+
.
When simplified, simplified to
and
simplified to
.
So 0.45 = +
.
Now, in the decimal form, = 0.3 and
= 0.15
So, 0.45 = 0.3 + 0.15
Hence 0.45 can be expanded in the fractional form as +
and in the decimal form as 0.3 + 0.15.

Using distributive property we can expand the expression as
3n - 5 = -8 x 6 + (-8) x 5n
To apply the distributive property to the equation
3n - 5 = -8(6 + 5n), we need to distribute the -8 to the terms inside the parentheses.
Using the distributive property, we have:
3n - 5 = -8 x 6 + (-8) x 5n
Simplifying further:
3n - 5 = -48 - 40n
Now, we can continue solving the equation using the simplified form as
3n + 40n = -48 + 5
43n = -43
n= -1.

Answer:
n=-1
Step-by-step explanation:
3n-5=-8(6+5n)
3n-5=-48-40n
add 40n to both sides
43n-5=-48
n=-1

Step-by-step explanation:
x and x+2 are the integers
- x*(x+2)= 7(x+x+2) -1
- x²+2x= 14x+14-1
- x² - 12x -13= 0
Roots of the quadratic equation are: -1 and 13.
So the integers pairs are: -1, 1 and 13, 15

To calculate the cost per patient over the four-year period, we need to add up the costs for each year and then divide by the number of years.
The costs per patient for the four years are:
Year 1: $43
Year 2: $46.5
Year 3: $49.8
Year 4: $53.63
To find the total cost over the four years, we add up these costs:
$43 + $46.5 + $49.8 + $53.63 = $193.93
Now, we divide the total cost by the number of years (which is 4) to find the average cost per patient over the four-year period:
$193.93 / 4 = $48.48
Therefore, the cost per patient over the four-year period is approximately $48.48.
Final answer:
The cost per patient over the four-year period is $193.16.
Explanation:
To find the cost per patient over the four-year period, we need to calculate the percent increase for each year and then multiply the percent increase by the previous year's cost. Here are the steps:
- Calculate the percent increase for each year:
- From $43 to $46.5: ($46.5 - $43) / $43 * 100% = 8.14%
- From $46.5 to $49.8: ($49.8 - $46.5) / $46.5 * 100% = 7.10%
- From $49.8 to $53.63: ($53.63 - $49.8) / $49.8 * 100% = 7.70%
- Multiply the percent increase by the previous year's cost for each year:
- Year 1: $43 * (1 + 8.14%) = $46.57
- Year 2: $46.5 * (1 + 7.10%) = $49.85
- Year 3: $49.8 * (1 + 7.70%) = $53.74
- Add the costs for each year: $43 + $46.57 + $49.85 + $53.74 = $193.16
Therefore, the cost per patient over the four-year period is $193.16.
