d = 2*3 -10 = -4
The n-th term of the sequence is
.. t[n] = 3 +d(n -1) = 7 -4n
Answer:
correct
Step-by-step explanation:
3(4)-2(4)+8=12
12-8+8=12
12=12

Step-by-step explanation:
Answer:
Option C) Nominal
Step-by-step explanation:
We are given the following in the question:
Variable:
Nation of origin
Nominal and ordinal:
- Categorical variables can further be divided as nominal and ordinal.
- Nominal variable are simple name variable and no numeric value is used to express such variable.
- Ordinal variable are the variable where position plays an important role but again numerical value is not used to express them.
Ratio and interval:
- Numerical data can be divided as ratio and interval.
- Ratio is the data that have true zero value.
- For interval, absolute zero have no meaning.
Thus, the given variable that is name of origin is a categorical variable.
It is a nominal variable as position plays no role in this.
Thus, the correct answer is
Option C) Nominal
Answer:
B)
−29
Step-by-step explanation:
2/5(2x − 12) = −28
Multiply each side by 5/2 to clear the fraction
5/2*2/5(2x − 12) = −28*5/2
2x-12 = -70
Add 12 to each side
2x-12+12 = -70+12
2x = -58
Divide by 2
2x/2 = -58/2
x = -29
