Answer:
Step-by-step explanation:
Since the number of samples is given as n = 30, we would determine the degree of freedom, df
df = n - 1 = 30 - 1
df = 29
Since the test statistic is given as 2.35 and the df = 29, we would determine the p value from the t distribution table. We will look for the row containing df = 29 and trace the two columns between which 2.35 falls. The result would also be in the row containing one tailed test. Therefore, the p-value falls between 0.025 and 0.01.
Answer: y=4x-1
Step-by-step explanation: the line goes through (-2,7) and is perpendicular to the line x-4y =24
Answer:
A sine function has the following key features:
Frequency = 1/4π
Amplitude = 2
Midline: y = 2
y-intercept: (0, 2)
I think it is y=3sin(4pix)+2 ? Am i correct?
Answer:
p(x) = x³ - 9x² + 4x + 120
Step-by-step explanation:
complex zeros occur in conjugate pairs
6 + 2i is a zero, hence 6 - 2i is a zero
the factors are therefore (x + 3) , (x - (6 + 2i)), (x - (6 - 2i)), hence
p(x) = (x + 3)(x - 6 - 2i)(x - 6 + 2i)
= (x + 3)((x - 6)² - 4i²)
= (x + 3)(x² - 12x + 36 + 4) ← i² = - 1
= (x + 3)(x² - 12x + 40)
= x³ - 9x² + 4x + 120 ← in standard form
1.50 x R, R being the rides a visitor rides.
