Answer:
a) Sample correlation coefficient, r = 0.7411
bi) test statistic, t = 4.102
bii) P-value = 0.000736
Step-by-step explanation:
a) The formula for the sample correlation coefficient is given by the formula:
r = 0.7511
b)
i) formula for the test statistic is given by the formula:
sample size, n = 4
t = 4.102
ii) Degree of freedom, df = n -2
df = 14 -2
df = 12
The P-value is calculate from the degree of freedom and the test statistic using excel
P-value =(=TDIST(t,df,tail))
P-value = (=TDIST(4.1,12,1)
P-value = 0.000736
X 25*24*23*22*21*20*19
which gives you
2,422,728,000
Answer:
So she earned 148 dollars and 50 cents or 148.5
Step-by-step explanation:
The bottom is (25 x 20) = 500 of whatever those units are, squared. Each long side is (25 x the depth of the pool, which we don't know), and each end is (20 x depth).
to find the vertical asymptote, set the denominator equal to zero and solve for x.
to find the horizontal asymptote, only evaluate the terms in the numerator and denominator that have the biggest exponent. Use the following rules (m is the exponent of the numerator and n is the exponent of the denominator):
m > n, then y = ∞ so there is no asymptote
m = n, then simplify the coefficients to determine the asumptote
m < n, then y = 
so the asymptote is y = 0
m = 2, n = 1 ⇒ m > n so y = ∞
Answer: there is no horizontal asymptote
