Answer:

12

Step-by-step explanation:

First you have to add the amount of pencils each person has

14 + 9 + 12 + 13 + 12

Which equals 60

Then, you have to divide the total by the answer you got from above

60 / 5

Which equals 12

The total distance of the race is 517.5 yards.

Remember the relation:

distance = speed*time.

We know that Janice runs at a constant rate (or speed), and covers 450 yards in 100 seconds.

Then her speed is:

S = (450 yd)/(100 s) = 4.5 yd/s

Now, we know that she finishes the race 15 seconds latter, in these 15 seconds she runs:

d =  (4.5yd/s)*15s = 67.5 yd

Adding that to the original 450 yards, the total distance is:

D = 450 yd + 67.5yd = 517.5 yd

Answer:

C. 37 miles

Step-by-step explanation:

0.50 + 1.50 = 20

        -1.50     -1.50

0.50 = 18.50

18.50 / 0.50 = 37

The value of the rate of growth in Japan is - 0.55.

From the question above, :Birth rate = 7.7 per thousand

Death rate = 9.8 per thousand

Net migration = 0.55 per thousand

The rate of growth can be calculated using the following formula:

r = (birth rate - death rate) + net migration

Where,r = rate of growth

birth rate = number of live births per thousand in a population in a given year

death rate = number of deaths per thousand in a population in a given year

net migration = the difference between the number of people moving into a country (immigrants) and the number of people leaving a country (emigrants) per thousand in a given year

Putting the values in the formula we get,r = (7.7 - 9.8) + 0.55r = - 1.1 + 0.55r = - 0.55.

Therefore, the rate of growth in Japan is - 0.55.

Your question is incomplete but most probably your full question was:

thenet migration is confusing me. i thought of using the formula:[ (births + immigration) - (deaths + emmigration)] / total

The average rate of change of the function over the given interval is -6

Step-by-step explanation:

The function we want to find its average rate of change is;

F(x) = 17 - x^2

Mathematically, the average rate of change of a function F(x) over an interval (a,b) can be calculated as;

{F(b) - F(a)}/(b-a)

According to this question, a = 1 and b = 5

F(a) = F(1) = 17 -(1)^2 = 17 -1 = 16

F(b) = F(5) = 17 - 5^2 = 17-25 = -8

So making the substitution; we have

(-8)-16/(5-1) = -24/4 = -6

By using recursion, the function can keep track of the number of sit-ups for each day, allowing Fatoumata to easily determine the number of sit-ups she needs to do on any given day.

To represent Fatoumata's daily exercise routine using recursion, we can define a recursive function that calculates the number of sit-ups she will do on a given day. Let's call this function "sit-ups".

The base case of the recursive function is when the day is equal to 1. In this case, the function should return the initial number of sit-ups, which is 5. For the recursive case, the function should return the sum of the sit-ups on the previous day plus 3. This can be represented as:
sit-ups (day) = sit-ups (day - 1) + 3
To summarize:
- Base case: sit-ups (1) = 5
- Recursive case: sit-ups(day) = sit-ups (day - 1) + 3
Therefore, the recursive function to represent Fatoumata's daily exercise routine is:
def sit-ups(day):
   if day == 1:
       return 5
   else:
       return sit-ups (day - 1) + 3
The recursive function "sit-ups" represents Fatoumata's daily exercise routine of doing sit-ups. It calculates the number of sit-ups she will do on a given day based on the number of sit-ups she did on the previous day. In the base case, which is when the day is equal to 1, the function returns the initial number of sit-ups, which is 5.

This is the starting point for Fatoumata's routine. In the recursive case, the function calculates the number of sit-ups on the current day by adding 3 to the number of sit-ups on the previous day. This means that each day after the first day, Fatoumata will do 3 more sit-ups than the day before. By using recursion, the function can keep track of the number of sit-ups for each day, allowing Fatoumata to easily determine the number of sit-ups she needs to do on any given day.

The recursive function "sitUps" accurately represents Fatoumata's daily exercise routine of doing sit-ups. By using this function, Fatoumata can easily determine the number of sit-ups she needs to do on any day, starting from 5 sit-ups on the first day and increasing by 3 sit-ups each subsequent day.

In the Clausius-Clapeyron equation, the variables related to the measured values that would typically be graphed on the x and y axes depend on the specific application.

Generally, the natural logarithm of the vapor pressure (ln P) is plotted on the y-axis, while the reciprocal of the absolute temperature (1/T) is plotted on the x-axis. The slope (m) and y-intercept (b) of the resulting linear graph have specific interpretations in the context of the equation.

The Clausius-Clapeyron equation relates the vapor pressure of a substance to its temperature. It is expressed as ln(P) = -ΔHvap/R * (1/T) + C, where P is the vapor pressure, ΔHvap is the enthalpy of vaporization, R is the gas constant, T is the temperature, and C is a constant. When graphing this equation, we often plot ln(P) on the y-axis and 1/T on the x-axis.

The graph obtained from plotting these variables follows a linear relationship. The slope of the resulting line, denoted as m, is equal to -ΔHvap/R. This slope provides valuable information about the enthalpy of vaporization, which is a measure of the energy required to convert a substance from its liquid phase to its gas phase. The y-intercept, denoted as b, represents the constant C in the equation, which accounts for any initial conditions or deviations from the ideal gas behavior.

By plotting ln(P) against 1/T, we can determine the slope and y-intercept of the linear graph. These parameters have specific physical interpretations and can provide insights into the thermodynamic properties of the substance under investigation. Analyzing the slope and y-intercept values can help in quantifying the enthalpy of vaporization and understanding the behavior of the substance as its temperature changes.

The null hypothesis is always a statement about the population parameter or the absence of a relationship or difference between variables in a statistical hypothesis test. It is typically denoted as "H0" and assumes no effect or no difference exists.

The null hypothesis can take different forms depending on the specific research question. For example, in a study comparing the mean scores of two groups, the null hypothesis might state that the means are equal. In a correlation study, the null hypothesis could assert that there is no correlation between variables.

The null hypothesis acts as a baseline for comparison in hypothesis testing. Researchers aim to gather evidence against the null hypothesis to support an alternative hypothesis. Statistical analysis helps determine the likelihood of observing the obtained data if the null hypothesis were true.

By specifying a null hypothesis, researchers can objectively evaluate the evidence and draw conclusions about the relationship or difference they are investigating.

In summary, the null hypothesis is a statement about the population parameter or lack of relationship/difference, which serves as a reference point for hypothesis testing. It helps researchers assess evidence and draw conclusions based on statistical analysis.

Step-by-step explanation:

Vertical asymptotes is x = -4 and horizontal asymptote is y = 1

What is an Asymptote?

An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote.

There are 3 types of asymptotes.

The given expression,

f(x) = (x² - 3x) / (x² + x - 12)

First, find Horizontal asymptote

so,

Horizontal asymptote (y) = (leading coefficient of numerator) / (leading coefficient of denominator)

leading coefficient of numerator = 1

leading coefficient of denominator = 1

y = 1/1

y =1 (Horizontal asymptote)

Now, find Vertical asymptote

so, let's simplify the expression f(x) = (x² - 3x) / (x + x - 12)

f(x) = (x(x - 3) ) / (x² + 4x - 3x - 12)

f(x) = (x(x - 3) ) / (x(x + 4) - 3 (x + 4) )

f(x) = (x(x - 3) ) / ( (x -3) (x + 4) )

f(x) = x / (x + 4)

Now, put the denominator = 0

x + 4 = 0

x = -4 ( Vertical asymptote )

Hence, Vertical asymptotes is x = -4 and horizontal asymptote is y = 1

Answer:

  x = 9

Step-by-step explanation:

You want the value of x that satisfies 6/40 = x/60.

This equation can be solved in one step: multiply by the inverse of the coefficient of x.

The coefficient of x is 1/60. Its inverse is 60/1 = 60. Multiplying the equation by 60 gives ...

  60(6/40) = 60(x/60)

  360/40 = x

  9 = x

__

Additional comment

Often, you will be advised to "cross multiply" as the first step in solving a proportion. Doing this would give you ...

  6(60) = 40(x)

Now, you would need to divide by the coefficient of x (or multiply by its inverse).

  6(60)/40 = (40x)/40

  360/40 = x = 9

This accomplishes in two steps what we did above in one step.

The rate of change of the circle diameter with respect to the radius is a constant value of 2.

The diameter of a circle is twice the radius, so we can write:

Diameter = 2 * Radius

To find the rate of change of the diameter with respect to the radius, we can take the derivative of both sides of this equation with respect to the radius:

diameter/d(radius) = d(2 * radius)/d(radius)

The derivative of 2*radius with respect to radius is simply 2, so we can simplify the equation:

diameter/d(radius) = 2

Therefore, the rate of change of the circle diameter with respect to the radius is a constant value of 2. This means that if we increase the radius by a small amount, the diameter will increase by twice that amount. Conversely, if we decrease the radius by a small amount, the diameter will decrease by twice that amount.

1. Probability that you have written the first 2 digits of your phone number. The probability of picking the first digit is 1/10. Now, since there are 9 digits left, the probability of picking the second digit (without replacement) is 1/9. Therefore, the probability of picking the first 2 digits of your phone number is:1/10 x 1/9 = 1/90

2. Probability that a person who tests positive actually has the disease, Incidence rate = 0.2% = 0.002The probability of not having the disease is: 1 - incidence rate = 1 - 0.002 = 0.998The false negative rate = 6% = 0.06The false positive rate = 5% = 0.05Let A be the event that a person has the disease, and B be the event that a person tests positive. We want to find P(A | B), the probability that a person who tests positive actually has the disease. By Bayes' theorem:P(A | B) = P(B | A) * P(A) / P(B)P(B) = P(B | A) * P(A) + P(B | A complement) * P(A complement)where P(B | A) is the true positive rate, which is 1 - false negative rate, and P(B | A complement) is the false positive rate, which is 0.05. Thus:P(B) = (1 - false negative rate) * incidence rate + false positive rate * (1 - incidence rate)= (1 - 0.06) * 0.002 + 0.05 * 0.998= 0.05084.Therefore, P(A | B) = P(B | A) * P(A) / P(B)= (1 - false negative rate) * incidence rate / P(B)= 0.00188 / 0.05084= 0.0369 (rounded to 3 decimal places).
