For the answer to the question above,
A - C = ( -2, 9) - (- 2 -3)
<span>= ( 0, 12) </span>
<span>AC = 12 </span>
<span>B - C = (7 - 3) - ( - 2 -3) </span>
<span>= (9, 0) </span>
<span>BC = 9 </span>
<span>ABC is a right -angled triangle with AC as the hypotenuse </span>
<span>AC = sqrt( 9^2 + 12^2) </span>
<span>= sqrt(81 + 144) </span>
<span>= srqt(225) </span>
<span>= 15 </span>
<span>Perimeter = 12 + 9 + 15 </span>
<span>= 36 units </span>
<span> So the answer is 36 units
</span>I hope my answer helped you.
Required probability is 0.8990
Given that,
p = 0.44
1 - p = 0.56
n = 736
0.01830
Converting Normal distribution to standard normal because A normal distribution is determined by two parameters the mean and the variance. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Hence it's easy to work with standard normal distribution.
P(0.14<<0.47) = P((0.41-0.44)/0.01830) < <(0.47-0.44)/0.01830
Using normal algebra we get:
= P(-1.64 < z < 1.64)
= P(z < 1.64) - P(z < -1.64)
= 0.9495 - 0.0505
= 0.8990
Thus, required probability is 0.8990
