Answer:
14
Step-by-step explanation:
The question is asking for the value of A when n = 2
So we just need to plug in 2 for n
A(2) = 10 + (<em>2</em>-1)(4) = 10 + (1)(4) = 10 +4 = 14
Answer:
Step-by-step explanation:
x=-1 is the counter example as ((-1)2)^(1/2)=1 and not -1.
Answer:
∠ BDC = 54°
Step-by-step explanation:
The inscribed angle BDC is half the measure of its intercepted arc , so
∠ BDC = 
× 108° = 54°
Answer:
(-2)^2 - 49
4 - 49 = -45
(-1)^2 - 49 = 1 - 49= -48
(0)^2-49= 0-49=-49
(1)^2-49=1-49=-48
(2)^2-49= 4-49= -45
the solution is either a or c
(x,y) ==> (-45,-2),(-48,-1),(-49,0),(-48,1),(-45,2)
(y,x)==> (-2, -45), (-1,-48), (-0,-49),(1,-48),(2,-45)
Step-by-step explanation:
The test perform to test the hypothesis is T-test.
A statistical test called a t-test is employed to compare the means of two groups. It is frequently employed in hypothesis testing to establish whether a procedure or treatment truly affects the population of interest or whether two groups differ from one another.
The three t-tests used to compare means are the one-sample, two-sample, and paired t-tests. The qualities of each are outlined in the table below, along with advice on how to pick the best test.
T-test formula:
t = (m - μ) / (s/√n)
t = t-test
m = mean
mu = theoretical value
s = standard deviation
n = variable set size
