Answer:
9.55 in
Step-by-step explanation:
The formula for the circumference of a circle (or the circum. of a basketball) is C = πd, where d is the diameter.
Here C =30 in = πd, so
d = (30 in) / π
= 9.55 in, approx.
The <em><u>correct answer</u></em> is:
A box and whisker plot
Explanation:
A box and whisker plot, or a box plot, displays what is called the "five number summary." This includes:
Median; LQ (lower quartile, or the median of the lower half of data); UQ (upper quartile, or the median of the upper half of data); lowest value; and highest value.
This will show the spread of data, and the mean can easily be added to this diagram.
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%
