Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.

mariarad [96]

The information you would need to create a two-variable equation is how much was her allowance and how much money did she have. Also you would need to know how many arcade games she played and how much each one cost and how many times she rode the Ferris wheel and how much each ride cost.

Hope this Helps!!

Factorize 9/16 x2 + xy + 4/9 y2

miskamm [114]

$\frac{9}{16} x^2 + xy + \frac{4}{9} y^2 = (\frac{3}{4} x)^{2} + xy + (\frac{2}{3}y)^{2} = (\frac{3}{4} x)^{2} + 2* \frac{3}{4} x * \frac{2}{3}y + (\frac{2}{3}y)^{2}$ $= ( \frac{3}{4}x + \frac{2}{3} y)^{2}$

The Institute of Education Sciences measures the high school dropout rate as the percentage of 16- through 24-year-olds who are

USPshnik [31]

The appropriate hypothesis which is used to test the dropout rate are $H_{0}:p > =0.081\\$ and $H_{1}: p < 0.081$ .

Given Drop out rate through 24 year old who are not enrolled is 8.1%, sample size=1000 and we have to find the hypothesis to test the drop out rate of the school.

The variable which needs to be studied is X=Number of individuals with age between 16 and 24 years old that are high school dropouts.

The parameter of interest is the proportion to high school drop outs is p.

Sample proportion= $p^{1}$ =0.065

The hypothesis can be formed as under:

$H_{0}:p > =0.081$ (null hypothesis)

$H_{1}:p < 0.081$ ( alternate hypothesis)

Null hypothesis is a hypothesis which is tested for its validity and alternate hypothesis is hypothesis which is opposite of null hypothesis means if null hypothesis is rejected then the alternate hypothesis will be true.

$Z_{H_{0} }=(p^{1}-p)/\sqrt{p*(1-p)/n}$

= $0.065-0.081/\sqrt{(0.081*0.0919)/1000}$

=-1.85

Hence the appropriate hypothesis are $H_{0}:p > =0.081$ and $H_{1}:p < 0.081$ .
