Which expression results in a rational number?

astraxan [27]

Answer:

option D is rational

Step-by-step explanation:

A rational number is a number that can be written in the form of fraction or integer

here in the given question

A) 1.5 + √1.5

now,

√1.5 is not rational as √1.5 = 1.2247448713915890490986420373529

hence A is not rational

b) 12 - √12

√12 is not rational as √12 = 3.4641016151377545870548926830117

hence B is not rational

c) $\frac{3}{4}\times\sqrt\frac{3}{4}$

here,

$\sqrt\frac{3}{4}$ is not rational

D) $\frac{25}{\sqrt{25}}$

now,

√25 = 5

hence,

$\frac{25}{\sqrt{25}}$ = $\frac{25}{5}$ = 5

therefore,

option D is rational

Given that MNOP is a rectangle, find x and y.

IceJOKER [234]

In rectangle, all the angles are 90°. ∠M =∠N = ∠O = ∠P = 90°. Therefore 2X - 10 = 90 and 3Y + 9 = 90. Therefore X = 50 and Y = 27. So option B is correct.

An appliance manufacturer stockpiles washers and dryers in a large warehouse for shipment to retail stores. Sometimes in handlin

Over [174]

Answer:

This is strong evidence that more than 2% get damaged

Step-by-step explanation:

The company goal is to keep the proportion of damaged machines below 2%

$H_o: p = 0.02$

$H_a: p > 0.02$

One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents

So, x = 6

n = 66

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{6}{66}$

Formula : $z=\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

$z=\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

$z=\frac{\frac{6}{66}-0.02}{\sqrt{\frac{0.02(1-0.02)}{66}}}$

$z=4.114$

So, the value of test statistic is 4.114

2) What is the P-value of the test statistic?

So, p value using calculator = .00002

p value < α

So, we accept the alternate hypothesis

So, This is strong evidence that more than 2% get damaged
