Answer:
x = 9/k
Step-by-step explanation:
Answer:
Definetely, it is reasonable. You may assume that a pet as a companionship will help the elderly feel more comfortable and therefore, happy. There are a few problems tough:
- There is no practical way of meassuring 'happiness'.
- Sometimes, the correlations of two factors may be a coincidence. Scientist should always consider this when they try to claim something byusing some backup logic, like we did.
- Even tough the statement makes some sense, you need to be aware that maybe is not completly positively correlated. Maybe having 20 more pets does not make an elderly happy if it alredy had 1 or 2.
Answer:
The equation is not a function.
Step-by-step explanation:
We are given that
![y^2=x^3+2](https://tex.z-dn.net/?f=y%5E2%3Dx%5E3%2B2)
![y=\pm\sqrt{x^3+2}](https://tex.z-dn.net/?f=y%3D%5Cpm%5Csqrt%7Bx%5E3%2B2%7D)
Function: It is mapping between the values of two sets A and B.
Each element of A has unique value in set B.
By definition of function
In given function
y has no unique value for each value of x.
Substitute x=0
![y=\pm \sqrt{0+2}=\pm \sqrt 2](https://tex.z-dn.net/?f=y%3D%5Cpm%20%5Csqrt%7B0%2B2%7D%3D%5Cpm%20%5Csqrt%202)
Hence, it is not a function.
Answer:
The formula T= 10d +20
A) what does each term on the right side of the equation represent?
- 10d⇒ 10 degrees increase per 1 km and 20 deg surface temperature
B) Estimate the depth where the temperature is 60 degrees C.
C) What is the approximate temperature at a depth of 4km?
Answer:
Point estimate of the corresponding population mean = $8,213
Step-by-step explanation:
Given:
Average cost of a wedding reception (x) = $8,213
Total number of sample (n) = 450
Standard deviation = $2185
Find:
Point estimate of the corresponding population mean
Computation:
Average cost of a wedding reception (x) = Point estimate of the corresponding population mean
Point estimate of the corresponding population mean = $8,213
