Answer:
y=1/10x+9
Step-by-step explanation:
i think, sorry if its wrong
The lengths of sides of a triangle have to satisfy the triangle inequality, which states that the sum of the two shorter sides must exceed the length of the third side.
Here 9+8=17 (not greater), so these segments do not form a triangle.
Answer:
We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 60
Sample mean, 
= 19.5
Sample size, n = 60
Alpha, α = 0.05
Population standard deviation, σ = 1.8
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now, 
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, it be concluded that the population mean is less than 20.
Answer:
A variable which can can be represented in numbers is known to be a quantitative variable.
Step-by-step explanation:
A variable is described as a characteristic of an object. Their values may occur more than once for a set of data.
A variable that can be represented in numbers is known to be a quantitative variable. Arithmetic operations can also be performed on these variables i.e. after performing arithmetic operations such as addition, subtraction, multiplication or division, some numbers can still be obtained as the result.
Quantitative variables can also be compared with each other to obtain meaningful results. Quantitative variables are of two types – discrete and continuous.
Discrete variables have whole numbers as their values whereas continuous variables can even have values in between the whole numbers.
Examples of quantitative variables are height, weight, time in the 100-yard dash, the number of items sold to a shopper.
