Answer:
write the percent divided by 100
Step-by-step explanation:
1) write the percent divided by 100.
2) if the percent is not a whole number, multiply both top and bottom by 10 for every number after the decimal point.
3) reduce (simplify) the fraction.
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%

Inverse functions (when ploted on the same graph as the original function) create a line of symmetry at X=Y.
C. Its sides are 6 times as long as that of the original square is the answer.
<u>Step-by-step explanation:</u>
Dilation is a kind of transformation which modifies the image size. The scale factor, otherwise called as scalar factor, means how much smaller or larger the image is. Whether the image is expanding or shrinking, the shape is retained.
In the process of dilation, we have to multiply the proportions of original image by the scale factor to find the size of an image. If the scalar factor is saying 6, then the image is inflated so its sizes are 6 times the original image.
Answer:
It is A
that fancy sign means the square root, not division.
B is untrue as well
