The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 4 . If there were 6597 total votes, how many yes votes were there?
The required number of people who voted for yes is 3665.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
here,
As mentioned in the question,
The people residing in the city voted on whether to raise property taxes. The ratio of yes to no is 5 to 4.
The multiplication of the proportion of yes to the total proportion of total votes gives the number of people who voted for yes.
The ratio of people yes to no = 5:4
Proportion of yes voted people = 5 / 9
The number of people who voted for yes = 5 / 9 × 6597 = 3665.

express this formula as a probabilistic relationship between poisson and gamma random variables. math.stackexchange
The gamma as well as Poisson distributions have an intriguing link. For each x, P(X x) = P(Y x), (1) where Y Poisson(x/), if X is a gamma(x, y) random variable and x is an integer.
What does the word "Poisson" mean?The probability density function f(x)=e−μμxx!, which approximates the binomial distribution and is frequently employed as a mathematical model of something like the number of outcomes acquired in an appropriate period of time and space, has a mean equal to its variance.
What is the purpose of Poisson?A Poisson distribution can be used to forecast or explain how many events will take place over a specific period of time or space. "Events" might include anything from illness occurrences towards to customer purchases to meteor strikes. Any defined period of time or area, such as 10 days or 5 square inches, can be used as the interval.

To calculate the height of the model, the architect should [divide] the actual height of the building by [10]
The height of the model is [6] inches.
How to complete the statement explaining how to find the height of the model the architect made?A scale is a factor by which a quantity is multiplied or divided in order to change its magnitude. Scales are commonly used to change the size of a figure without changing its shape or orientation.
Given:
A scale = 1 inch represents 10 feet
The height of the actual building = 60 feet
Since the model is a smaller version of the actual building, in order to get the height of the model, you have to divide the height of the actual building by the scale (10).
Thus, height of the model = 60/10 = 6 inches

What is inverse proportion?Two quantities are said to be in inverse proportion if an increase in one leads to a decrease in the other quantity and a decrease in one leads to an increase in the other quantity". In other words, if the product of both the quantities, irrespective of a change in their values, is equal to a constant value, then they are said to be in inverse proportion.
It takes 30 minutes either Paul or Chris to change the tire if both of them should work at the same rate, then the time of changing a tire would reduce.
so the time taken one tire by the two men 30/2 = 15 minutes.

Four distributions, labeled (a), (b), (c), and (d) are represented below by their histograms. Each distribution is made of measurements. Without performing any calculations, order their respective means , , , and .
The ranking of the data-sets according to their respective means is given as follows:
[tex]\mu_C < \mu_D < \mu_B < \mu_A[/tex]
How to calculate the mean of a data-set?The mean of a data-set is calculated as the sum of the values of all the observations divided by the number of observations.
In this problem, all the distributions have the same number of observations, hence the means are ranked from the highest sum.
The squares give the number of times that each observation appears in the data-sets.
The smallest mean is the mean of data-set C, as it is the only one with three measures of eight, while the other data-sets have four measures of eight.
Then the greatest mean is of data-set A, as it is the only with an observation of 6, and then data-set B has a greater mean than data-set D, as it has an observation of five while data-set D has an observation of three.

For each binomial probability statement below determine the corresponding normal distribution probability statement after a continuity correction. P(x> 118); P(x<118); P(x > 118)?
The probability statements after continuity correction are given as follows:
P(x > 118) = P(x > 117.5).P(X < 118) = P(X < 118.5).P(X = 118) = P(117.5 < x < 118.5).What is continuity correction?Continuity correction is used as a "correction" when a continuous distribution is used to approximate a discrete distribution. One example of this is the approximation of the binomial distribution to the normal distribution.
Hence, using continuity correction, the range of values that corresponds to a number of exactly x is given as follows:
x - 0.5 < x < x + 0.5.

You want the probability that a randomly chosen 8th grader will play the guitar.
Eighth gradersThe table tells us that there are 4 eighth grade students that play the guitar. The total number of eighth grade students is 4+10+6+3 = 23. When one is chosen at random, the probability they play the guitar is ...

Step-by-step explanation:
In general, dogs can run 15-20 mph
humans can run 6-8 mph
You are significantly slower than the dog,
the fastest human is around 27 miles per hour, unfortunately, even if you were this fast
the fastest dog can run 40 miles per hour as an estimate
even house cats can run at 30 mph maximum if they really wanted,
You have no chance of outrunning this dog, and barely a chance of outsmarting it if that option was available, in conclusion, the dog is chasing you at a speed of around 30 mph about 6-7x more than your own speed with no chance of outrunning it(the dog).

3. (x, y) = (20, 30)
4. (x, y) = (30, 4)
Step-by-step explanation:
You have equilateral triangles in two different configurations, and you want to find the values marked x and y.
3.All of the angles marked with an arc are congruent, so all are 60°. The angle marked 80° is an external angle to the top/left triangle. Its value is the sum of the values of the remote interior angles:
80° = 60° +x°
20° = x° . . . . . . . subtract 60°
x = 20
The sides of the equilateral triangle are congruent, so all are length 46. That means the right side is ...
16 +y = 46
y = 30 . . . . . . . subtract 16
(x, y) = (20, 30)
4.All of the angles marked with an arc are congruent, so all are 60°. The top 60° angle of the equilateral triangle is an external angle to the isosceles triangle at top/right. Its two base angles are the remote interior angles with respect to that 60° exterior angle, so their sum is 60°:
x° +x° = 60°
x = 30
The two marked legs of the isosceles triangle are both 20, which means all sides of the equilateral triangle are length 20.
5y = 20
y = 4 . . . . . . . divide by 5
(x, y) = (30, 4)

Claire said 4/3 /5/2 is 10/3. She reasoned 4/3 *5 = 20/3 and 20/3 / 2= 10/3
Clare's answer and reasoning are incorrect because she performed the multiplication operation (4/3) × 5 = 20/3 before the division operation and the correct quotient is 8/15, not 10/3.
To perform the division operation (4/3) ÷ (5/2), we need to first divide the numerator by the denominator.
This gives us (4/3) ÷ (5/2) = 8/15.
Thus, Clare's reasoning is incorrect because she did not apply the order of operations when simplifying the expression.
Instead, she performed the multiplication operation (4/3) × 5 = 20/3 before the division operation (20/3) ÷ 2 = 10/3.
Therefore, the correct quotient is 8/15, not 10/3.

The leading team scored 27.43 points per game in basket ball game.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
The points scored by current leader in 77 basket ball game = 2112,
And the points scored by second place player in 74 game = 2020.
The point scored by players in one match, use ratio property,
By current leader,
Points scored in 77 games = 2112
points scored in 1 game = 2112/77 = 27.43
By second place leader,
Points scored in 74 games = 2020,
