Answer: 1/10 or 0.1
Step-by-step explanation: 2/5 x 1/4 = 2/20 or simplified 1/10
Answer:
B -0.104
Step-by-step explanation:
Step 1: Write the formula for correlation
r = total xy
√Total x² x Total y²
Step 2: Make a table to calculate all values
Table is attached in the picture below
Step 3 : Solve
Mean of X = Total X/ Total number of X
= 507/12
= 106.33
Mean of Y = Total Y/ Total number of Y
= 1276/ 12
= 42.25
r = total xy
√Total x² x Total y²
r = -352.05/ √3656.25 x 3122.66698
r = -0.104
-0.104 is negative
This negative correlation means there is an inverse correlation between variables.
For the shoe size be equal to the length of the foot, this means that L must be equal to S. Now, since we have different equations depending on your gender, we first check the conditions for man.
Since S = 3L - 22 for men, for a person to have a foot length equal to his shoe size, we equate L to S as shown below.
L = S
L = 3L - 22
2L = 22
L = 11
Thus, we can see that men with 11-inch foot would have the same shoe size number. We can apply similar approach to find the length of a woman's foot that satisfies our conditions as shown.
L = S
L = 3L - 21
2L = 21
L = 10.5
Hence, a woman with a 10.5-inch foot have 10.5 for a shoe size as well.
Answer:
man: 11 inches
woman: 10.5 inches
Omg you need to find the quadrant 1,2,3,4 then once you doo you can put your number
True, <span>Conditional probability is </span><span>the probability of an event ( </span>A<span> ), given that another ( </span>B<span> ) has already occurred.</span>
