Answer:
Power
Step-by-step explanation:
An hypothesis is usually formulated at the beginning of research, it is usually in line with the problem statement and gives the possible outcome.
An hypothesis is either accepted or rejected.
Power in hypothesis is the probability of rejecting null hypothesis when it is false. It helps in making a correct decision by rejecting the null hypothesis when it is not true.
power ranges between 0 to 1 when it is close to 1 it is said to be very strong and has the probability of rejecting a null hypothesis when it is not true.
Power helps to avoid a type II error in statistics.
formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees

Answer:
aₙ = aₙ₋₁ + n + 1
Step-by-step explanation:
a₁ = 2
a₂ = 2 + 2 + 1 = 5
a₃ = 5 + 3 + 1 = 9
a₄ = 9 + 4 + 1 = 14
a₅ = 14 + 5 + 1 = 20
Answer:
started off from maximum, so f(x) = acos(bx)
max(f(x))=a=4
f(x)=4cos(bx)
the period is T = 2π
b=2π/T=2π/2π
b=1
f(x)=4cos(x)
Correct answer is the last one.
Function because for every x only one value of y,
not one-to-one because, 2 values of x have the same value of y.
