A researcher is interested in determining if the more than two thirds of students would support making the Tuesday before Thanks

giving a holiday. The researcher asks 1,000 random selected students if they would support making the Tuesday before Thanksgiving a holiday. Seven hundred students said that they would support the extra holiday. What is the null and alternative hypothesis?

Answer:

The null hypothesis is, {H₀}: p = 0.66, H₀: p = 0.66 .

The alternative hypothesis is, {Hₐ}: p > 0.66, Hₐ: p > 0.66

Step-by-step explanation:

Let p represent the proportion of students who are supportive of making the day before Thanksgiving a holiday.

Since two populations are considered, the alternative hypothesis for the difference of the means of the two populations has to be stated.

The proportion of two-third students are supportive of making the day before Thanksgiving a holiday is p = 0.66 obtained as shown below:

The null hypothesis is,

{H₀}:p = 0.66, H₀: p = 0.66

The alternative hypothesis is,

{Hₐ:p > 0.66, Ha: p > 0.66

The null hypothesis is, {H₀}: p = 0.66, H₀: p=0.66 .

The alternative hypothesis is, {Hₐ}: p > 0.66, Hₐ: p > 0.66

Answer:

$R=\$145.12$

Step-by-step explanation:

<u>Compound Interest</u>

This is a well-know problem were we want to calculate the regular payment R needed to pay a principal P in n periods with a known rate of interest i.

The present value PV or the principal can be calculated with

$P=F_a\cdot R$

Solving for R

$\displaystyle R=\frac{P}{F_a}$

Where Fa is computed by

$\displaystyle F_a=\frac{1-(1+i)^{-n}}{i}$

We'll use the provided values but we need to convert them first to monthly payments

$i=7\%=7/(12\cdot 100)=0.00583$

$n=3*12=36$

$\displaystyle F_a=\frac{1-(1+0.00583)^{-36}}{0.00583}$

$F_a=32.386$

Thus, each payment is

$\displaystyle R=\frac{4,700}{32.386}=145.12$

$\boxed{R=\$145.12}$

What is the value of (9^7) ^3/14, in simplest terms? a0

s2008m [1.1K]

Answer:

27.

Step-by-step explanation:

It is one property of exponents that for any numbers <em>a, b,</em> and c

$(a^b)^c=a^{bc}$

Therefore, using this property the expression $(9^7) ^{3/14}$ becomes

$(9^7) ^{3/14} =9^{(7*\frac{3}{14} )}$ .

and when when simplify the exponents, we get:

$9^{(\frac{21}{14} )}= 9^{\frac{3}{2} }= (9^{\frac{1}{2} })^3$ .

Since for any number $a^\frac{1}{2} =\sqrt{a}$ <em>( </em> $\dfrac{1}{2}$ <em> in the exponent means the square root) , </em> $(9^{\frac{1}{2} })^3$ is rewritten as

$(\sqrt9} )^3$

which simplifies to

$(\sqrt9} )^3=3^3 =\bold{27}$

Thus,

$\boxed{ (9^7) ^{3/14}=27}$
