Two number that multiply to 24 and add up to minus 11

yulyashka [42]

Hello,

Let's x and y the 2 numbers

x*y=24
x+y=-11==>x=-11-y
==> (-11-y)y=24
==>-11y-y²-24=0
==>y²+11y+24=0
Δ==11²-4*24=25=5²
y=(-11+5)/2 or y=(-11-5)/2
==>(y=-3 and x=-11+3) or (y=-8 and x=-11+8)

Sol={(-8,-3),(-3,-8)}

The 2 numbers are -3 et -8.

How large a sample must be drawn to estimate population proportion confidence interval width to within .04, with 95% confidence,

lubasha [3.4K]

Answer:

Sample size 'n' = 384

Step-by-step explanation:

<u><em>Explanation:</em></u>-

Given margin of error = 0.04

The sample proportion 'p'= 0.80

The margin of error is determined by

$M.E = \frac{Z_{\alpha } \sqrt{p(1-p)} }{\sqrt{n} }$

$0.04 = \frac{1.96 \sqrt{0.80(1-0.80)} }{\sqrt{n} }$

Cross multiplication, we get

$\sqrt{n} = \frac{1.96 \sqrt{0.80(1-0.80)} }{0.04 }$

√n = 19.6

Squaring on both sides , we get

n = 384.16≅384
