Jessica and Callista go the local burger joint. They both want to buy the meal deal. Jessica has 34 of the money needed to buy t

olga_2 [115]

The original price of the meal deal if they would have exactly enough money to buy two of the meal deal is $4

<h3>How to write and solve equation?</h3>

let

x = cost of the meal

Both = 2x - 3

Jessica = 3/4x
Callista = 1/2x

3/4x + 1/2x = 2x - 3

(3+2)x / 4 = 2x - 3

5/4x = 2x - 3

5/4x - 2x = - 3

(5-8)x/ 4 = -3

-3/4x = -3

x = -3 ÷ -3/4

= -3 × -4/3

= 12/3

x = $4

Answer: The standard error for sample is 0.0686 .

Step-by-step explanation:

We know that the formula to find the standard error is given by :-

$S.E.=\dfrac{s}{\sqrt{n}}$

, where s = standard deviation

n= Sample size

As per given , we have

s= $0.4 and n= 34

Then , the standard error for sample is given by :-

$S.E.=\dfrac{0.4}{\sqrt{34}}=\dfrac{0.4}{5.83095189485}\\\\=0.0685994340569\approx0.0686$

Hence , the standard error for sample is 0.0686 .
