Answer:

$1,313.3 per month

Step-by-step explanation:

A=p(1+r/n)^nt

P=principal=$75,000

r=interest rate=7.2%=0.072

t=20 years

n=12 months

A=p(1+r/n)^nt

=75,000(1+0.072/12)^12*20

=75,000(1+0.006)^240

=75,000(1.006)^240

=75,000(4.2026)

=315,195

A=$315,195

The term of Lauren's loan=20 years

20 years×12 months=240 months

Lauren's pay per month =$315,195/240

=$1,313.3125

Approximately $1,313.3 per month

A hypothesis test is conducted at the .05 level of significance to test whether or not the population correlation is zero. If th

Answer:

Th computed value of the test statistic is 3.597

Step-by-step explanation:

The null and the alternative hypothesis is as follows:

Null Hypothesis:

\mathbf{H_o:} the population correlation coefficient is equal to zero

\mathbf{H_a:} the population correlation coefficient is not equal to zero

The test statistics for Pearson correlation coefficient is thus computed as :

t =\dfrac{r \sqrt{(n-2)}} { \sqrt{(1-(r)^2)} }

where;

r = correlation coefficient = 0.60

n = sample size = 25

So;

t =\dfrac{0.60 \sqrt{(25-2)}} { \sqrt{(1-(0.60)^2)} }

t =\dfrac{0.60 \sqrt{(23)}} { \sqrt{(1-0.36} }

t =\dfrac{0.60 *4.796} {0.8}

t = 3.597

Comparing to a critical value of t (23 degrees of freedom two-tailed value) = 2.069

Decision Rule:

Since computed value of t is greater than the critical value of t; We reject the null hypothesis and accept the alternative hypothesis.

Conclusion:

We conclude that the population correlation coefficient significantly differs from 0 at 5% (0.05) level of significance.

Answer:

sqrt(-8x+5)

Step-by-step explanation:

(5-8x)

-----------------

sqrt(-8x+5)

We need to rationalize the denominator

(5-8x)               sqrt(-8x+5)

----------------- * ---------------

sqrt(-8x-5)         sqrt(-8x+5)

(5-8x)               sqrt(-8x+5)

----------------- * ---------------

(-8x+5)

The first term cancels
