lana [24]

Answer: The equation would NOT help us solve for the length and width of the classroom is " $x + 2y = 90$ ".

Step-by-step explanation:

Let y be the width of the rectangular classroom floor and x be the length of the rectangular classroom floor .

Given ,

The perimeter of a rectangular classroom floor is 90 feet.

The length of the floor is twice the width.

i.e. Length =2 (width)

i.e. x= 2y ..(i)

Also, perimeter = 2(length+width)

$i.e. 2(x+y)=90\\\\\Rightarrow\ 2x+2y=90$

When we put value of x from (i), we get

$2(2y) + 2y = 90$

Hence, the equation would NOT help us solve for the length and width of the classroom is " $x + 2y = 90$ ".

A survey of 5,913 American adults concludes that 53% of them prefer Captain America to Ironman. Find the Margin of Error. Type y

Virty [35]

Answer:

1.3%

Step-by-step explanation:

Phat = 0.53

1 - phat = 1 - 0.53 = 0.47

Sample size, n = 5913

Assume the confidence level = 95%

Zcritical at 95% = 1.96

Margin of Error = Zcritical * √(phat(1 -phat)) / n

Margin of error :

1.96 * √((0.53 * 0.47) / 5913)

1.96 * 0.0064905

= 0.0127215

= 0.0127215 * 100%

= 1.272%

= 1.3%
