Answer:
a. N(500, 100)
Step-by-step explanation:
The normal probability distribution, with mean M and standard deviation S, can be represented in the following notation.
N(M,S).
In this problem, we have that:
Mean = 500
Standard deviation = 100
Which of the following options would be the correct way to represent the information?
a. N(500, 100)
Bse is 10
x^m, x is base of exponent
Answer:
<h3>THE SCIENCE OF COLLECTING, REVIEWING AND ANALYSING DATA.</h3>
There are 12 inches in a foot, so 9ft = 108in. Also, 80% = 0.8. Therefore the formula is:
h(n) = 108 * 0.8^n.
To find the bounce height after 10 bounces, substitute n=10 into the equation:
h(n) = 108 * 0.8^10 = 11.60in (2.d.p.).
Finally to find how many bounces happen before the height is less than one inch, substitute h(n) = 1, then rearrage with logarithms to solve for the power, x:
108 * 0.8^x = 1;
0.8^x = 1/108;
Ln(0.8^x) = ln(1/108);
xln(0.8) = ln(1\108);
x = ln(1/108) / ln(0.8) = -4.682 / -0.223 = 21 bounces
