quester [9]

Answer:1866

Step-by-step explanation:

Given

n=200

x=118

Population proportion P= $\frac{118}{200}$ =0.59

$\alpha$ =0.005

Realiability =99%

$Z_{\frac{\alpha }{2}}=2.576$

Margin of erroe is given by $\sqrt{\frac{p\left ( 1-p \right )}{N}}$

0.03= $\sqrt{\frac{0.59\left ( 1-0.59 \right )}{N}}$

85.667= $\sqrt{\frac{N}{0.6519}}[tex]N=1865.88[tex]\approx 1866 Students$

Solve using the quadratic formula. h2 + 8h + 8 = 0 Write your answers as integers, proper or improper fractions in simplest form

Marina86 [1]

A=1 b=8 c=8
h = [-8 +-sq root(64 - 4*1*8)] / 2
h = [-8 +-sq root(32)] / 2
h1 = -4 + 2.8284271247 
h1 = -1.1715728753 
h2 = -4 - 2.8284271247
h2 = - 6.8284271247

The probability of picking two black marbles from a box at random without replacement is 10/91 .

sasho [114]

The probability of the 2 events are multiplied to get the result 10/91

so we have the relation 5/14 * x = 10/91

where x is the probability of drawing the second black

so x = 10/91 * 14/5 = 4/13 answer
