Answer:

0.03

Step-by-step explanation:w

standard deviation = ( p(1-p) / n)1/2

p= sample proportion= 55%

n= sample size = 900

standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2

= (0.55*0.45 / 900)1/2

= 0.0165

margin of error = critical value*standard deviation

[ from graph critical value = 2]

margin of error = 2*0.0165=0.033

What is 10/n = 15/45 solved?

The answer would be 3.33333. I think because 10*15= 150. Then you would divide it by 45 and you would get 3.333. If you get it wrong im sorry.

Given: AB parallel to DC prove: ABE ~ DCE

slava [35]

The reasons would be:

alternate interior angles
vertical angles
AAA (all angles are congruent)

Since we know that the two line segments are parallel, this means that BC is a transversal. Using that knowledge with the position of ABE and DCE, we see these are alternate interior angles.

AEB and DEC are vertical angles, since they share only a vertex.

This gives us 3 congruent angles, so the triangles must be similar.

The sum of two consecutive number is 15. the number are and solve

Fiesta28 [93]

By Question it's given that the sum of two numbers is 15 . And we need to find out the numbers. So ,

Let us take :-

First number = x
Second number = x + 1

According to the Question :-

$\sf\implies x + x +1=15\\\\\sf\implies 2x = 15-1\\\\\sf\implies 2x =14 \\\\\sf\implies x =14/2 \\\\\sf\implies\red{ x = 7 }$

Therefore :-

First number = 7
Second number = 8

Hence the two numbers are 7 and 8.
