This is the concept of probability and statistics, to solve the question we proceed as follows;
given that the word the word science has 7 letters;
the probability of selecting a c in the first draw will be:
P(selecting c in first draw)=2/7
Probability of selecting a c on the second draw will be:
P(selecting a c in second draw)=1/6
since these two events are mutually independent, the probability of selecting c twice will be:
P(selecting C twice)=1/6*2/7
=1/21
The rule for dilation (about the origin) is
(x,y)->(kx,ky) where k is the dilation factor.
Let's try a few points,
D(4,8)->D'(2,4)=((1/2)4,(1/2)8) => k=1/2
F(8,8)->F'(4,4)=((1/2)8,(1/2)8) => k=1/2
We can repeat the same verification with points E & G with the same results, so
Answer: scale factor is 1/2, or 0.5.
Answer:
9
Step-by-step explanation:
40% of 15 = 6.
1/6 of 18 = 3.
6 + 3 = 9.
