Give an example of a ratio that is not a rate. Tell why it is not a rate.
1 answer:
Answer:
Ratio is it rate. Can you do the rate of numbers.
For example, if we say: If the car was very high to acceleration at least, 1,000 km/h.
If Usain Bolt was won on the Olympics, he has 27 km/h.
Hmm, the ratio isn't rate at all. This method can do the non rate. For example, if we say: If the gas price at BP, there's $100 per year.
Step-by-step explanation:
With this method, you must solve the ratio isn't rate.
For there's the group, this was what do you say, it's GCF, or greatest common factor. With this GCF method, for example: if we say, the European Parliament, and the MPs, are divided by gender, if we divide by male and female. For more examples, see the answer at the above with the picture
With this method of the rate, there are no of speed, price, or something else.
There are some examples like the km/h, representing the Kilometers per hour.
Hopefully with this helpful example

Answer:
Step-by-step explanation:
Hello!
The variable of interest is
X: The number of emergency service calls made by the volunteer ambulance service of Walterboro, South Carolina for 50 days.
a)
In the first column, you have the possible number of emergency calls made, in the second column, you have the observed absolute frequency (fi) for each value of the variable.
To establish the probability distribution you have to calculate the relative frequency (hi) for each value of X.
The formula for the relative frequency is
hi= fi*n where i= 0, 1, 2, 3, 4
X₁= 0
f₁= 8
h₁= 8/50= 0.16
X₂= 1
f₂= 10
h₂= 0.20
X₃= 2
f₃= 22
h₃= 22/50= 0.44
X₄= 3
f₄= 9
h₄= 9/50= 0.18
X₅= 4
f₅= 1
h₅= 1/50= 0.02
(See attachment)
b)
The variable of interest is a cuantitative discrete variable, so this is an example of a driscrete distribution.
Discrete variables are numerical and take certain numbers within its range of definition, contrary to the continuous variables that can take any value within the range of definition of the variable.
Another example of a discrete variable is "the money", If the variable is "I have at most 10 dollars in my wallet", the range of definition goes from 0 dollars to 10 dollars.
c) To calculate the mean when the data is arranged in a frequency table you have to use the following formula:
X[bar]= ∑Xihi= (0*0.16)+(1*0.2)+(2*0.44)+(3*0.18)+(4*0.02)= 1.7
This means that they expect an average of 1.7 calls per day.
d) The formula for the standard deviation is:
∑X²fi= (0²*8)+(1²*10)+(2²*22)+(3²*9)+(4²*1)= 195
∑Xfi= (0*8)+(1*10)+(2*22)+(3*9)+(4*1)= 85
I hope this helps!
Answer:
Kindly check attached picture ; 37.5%
Step-by-step explanation:
Let:
S = number of science fiction movie viewers
H = number of horror movie viewers
A = number of adventure movie viewers
From the information given :
n(SnHnA) = 5
n(SnH) only = 15 - 5 = 10
n(SnA) only = 25 - 5 = 20
n(AnH) only = 5 - 5 = 0
n(S) only = 40 - (10+5+20) = 5
n(H) only = 40 - (10+5+0) = 25
n(A) only = 50 - (5 + 20 + 0) = 25
2.) % of science fiction movie to horror movie fans
Total Science fiction movie fans = n(S) = 40
Science fiction and Horror movie fans = n(SnH) = 15
[n(SnH) / n(S)] * 100%
(15 / 40) * 100%
0.375 * 100%
= 37.5%
