Step-by-step explanation:
A term is a number, a variable, or a constant multiplied by a variable or variables.
Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different.
A coefficient is a multiplicative factor in some term of a polynomial (expression).
Constant is a term in the algebraic expression that contain only number.
n + 5n = n + 5n + 0
terms: n, 5n
like terms: n, 5n
coefficients: 1, 5
constant: 0
simplified form: n + 5n = 6n
term: 6n
coefficient: 6
constant: 0
=======================
12c - c = 12c - c + 0
terms: 12c, -c
like terms: 12c, -c
coefficients: 12, -1
constant: 0
simplified form: 12c - c = 11c
term: 11c
coefficient: 11
constant: 0
========================
-4j - 1 - 4j + 6
terms: -4j, -1, -4j, 6
like terms: -4j, -4j and -1, 6
coefficients: -4, -4
constants: -1, 6
simplified form: -4j - 1 - 4j + 6 = (-4j - 4j) + (-1 + 6) = -8j + 5
term: -8j, 5
coefficient: -8
constant: 5
Answer:
a) 
b) Null hypothesis:
Alternative hypothesis: 
And we can use a t test procedure in order to check if the true mean is equat to the desired value.
Step-by-step explanation:
For this case we know that this:
Claim: The mean pulse rate (in beats per minute) of adult males is equal to 69.5 bpm
Part a
If we convert this with symbols we can write this as:
Part b
We have the following info given:
represent the sample mean
represent the sample size
We have the following system of hypothesis:
Null hypothesis:
Alternative hypothesis:
And we can use a t test procedure in order to check if the true mean is equat to the desired value.
1,212 devided by 4 =
303
I hope this helps!
