Answer:
t(n) = 54 is not a term in the sequence
Step-by-step explanation:
To know if t(n) = 54 is a term in the sequence, let us substitute the value of t(n) into the equation. This is illustrated below
t(n) = 2n — 3
t(n) = 54
54 = 2n — 3
Collect like terms
54 + 3 = 2n
57 = 2n
Divide both side by the coefficient n i.e 2
n = 57/2 = 28.5
since the value of n obtained is decimal number, therefore, t(n) = 54 is not a term in the sequence
The correct answer is 4 and 1/8
Answer:
x=20
Step-by-step explanation:
Since they are congruent triangles
A = D
3x-10 = 2x+10
Subtract 2x from each side
3x-10-2x = 2x+10-2x
x-10 = 10
Add 10 to each side
x-10+10 = 10+10
x=20
Answer:
4% is a statistic and 1% is a parameter
Step-by-step explanation:
First, let's remember the differences between parameters and statistics:
Parameters are values that describe data of the entire population.
Statistics are values that describe data from a sample.
The value of 1% refers to "all of the parts", which is the population of over 1 million parts, thus 1% is a parameter.
The value of 4% refers to the "100 selected", which is the sample of 100 parts, thus 4% is a statistic.
Therefore, 4% is a statistic and 1% is a parameter.
