12 adult elephants, 6 young elephants = 18 total :)
Answer:
a) Mean, median, mode = 56.5
b) 
Step-by-step explanation:
Normally distributed data have the same value for the mean, median and mode. This value is the addition of the maximum value by the minimum, divided by 2.
Also, the standard deviation in a normally distributed sample can be approximated by the following formula:
So
a) Estimate the values of Mean, Median, and Mode.
Highest value = 98
Minimum value = 15
b) Estimate the value of the standard deviation of these data
Max = 98
Min = 15
So
Answer:
(7, 10.5)
Step-by-step explanation:
just going to use substitution here.
so you would substitute the y value in the equation x-2y=-14 with 2x-3.5.
it should look like: x-2(2x-3.5)=-14
solve the equation and you get x=7.
plug in 7 for x in either equation and you get y= 10.5.
These are two questions and two answers.
Question 1. The ordered pair given in the first row in the table can be written using function notation as?
Answer: f(-2) = 1
Justification:
In functions, the notation f(x) denotes the image (ouput) obtained when you apply the rule (function) to the value x, i.e. x is the input.
So, for example, the image of x = 5 is f(5), the image of x = 2,000 is f(2,000), the imaga of x = - 100.5 is f(-100.5).
In the table, the first row shows that the image of x = -2 is 1, so f(-2) = 1, and that is the answer to the question.
Question 2. f(x) = –2 when x is?
Answer: x = 4.
Justification.
You are requested to find which value of x makes the function f(x) equals -2.
Therefore, you have to see that in the third row of the table it is shown that f(x) is - 2 when x = 4., and that is the answer.
All the following expressions mean the same and are used when you deal with functions:
- the ordered pair (4, -2),
- the image of 4 is - 2
- the preimage of -2 is 4
- f(4) = -2
- f(x) = -2, when x = 4.
Let us assume that the first company the cab flat rate is 5$ and the cap driver charges 2$ per mile .for the second company the cab flat rate is 3$ and the cab driver charges 3$ per mile.
a. the company charges per ride at least 5$ and an extra 2$ per mile
b.the equation we will choose is slope intercept since we know the
y-intercept which is the cab flat rate .
y=mx+b
where
m :is the slope
b:is the y-intercept
y:total amount
x. is the milage
total amount=2x+5.
c.the slope will be 2$ which is the change in amount per mile.the y-intercept will be the cab's flat rate.
