Answer:

The converse of Pythagorean Theorem states:

<em>If the square length of the longes side of a triangle is equal to the sum of the squares of the other two sides, then it's a right triangle.</em>

<em />

We use the converse of Pythagorean Theorem to prove that a triangle is a right triangle. It's like the inverse use of the theorem. Often, this theorem is used to find the length of a side of a triangle when we already know it's a right triangle. However, when we don't know that is a right triangle, we use the converse to prove it.

Researchers conducted a study to find out if there is a difference in the use of ereaders by different age groups. randomly sele

ikadub [295]

No, there is significant difference in the use of e readers by different age groups.

Given sample 1 ( 29 years old) $n_{1}$ =628, $p_{1}$ =7%, sample 2( 30 years old) $n_{2}$ =2309, $p_{2}$ =0.11.

We have to first form hypothesis one null hypothesis and other alternate hypothesis.

$H_{0}:$ π1-π2=0

$H_{1}:$ π1-π2≠0

α=0.05

Difference between proportions $p_{1}-p_{2} =-0.04$

$p_{d}=0.07-0.11=-0.04$

The pooled proportion needed to calculate standard error is:

$p=(X_{1} -X_{2} )/(n_{1} +n_{2} )$

=(44+254)/(628+2309)

=0.10146

The estimated standard error of difference between means is computed using the formula:

$S_{p_{1} -p_{2} }=\sqrt{p(1-p)/m_{1}+p(1-p)/n_{2} }$

= $\sqrt{0.101*0.899/628+0.101*0.899/2309}$

= $\sqrt{0.000143+0.00003}$

= $\sqrt{0.000173}$

=0.01315

Z= Pd-(π1-π2)/ $S_{p_{1} -p_{2} }$

=-0.04-0/0.013

=-3.0769

This test is a two tailed test so the p value for this test is calculated as (using z table)

p value:2 P(Z<-3.0769)

=2*0.002092

=0.004189

P value< significance level of 5%.

Hence there is enough evidence to show the claim that there is a significant difference in the use of e readers by different age groups.

A flower box in the shape of a right rectangular prism is made of thin metal, shown below. The box has length 90 centimeters (cm

Paul [167]

The volume of the box is
.. V = (90 cm)*(45 cm)*(45 cm) = 182,250 cm³
The empty 15% of the volume is then
.. empty volume = 0.15*182,250 cm³ = 27,337.5 cm³

This will require
.. (empty volume)/(volume / bag) = 27,337.5 cm³ / (28,316 cm³/bag) ≈ 0.97 bag
to fill.

Selection A. 1 bag is appropriate.
