The correlation coefficient (r) of the height and weight is 0.40391008.
Rounded, It will be 0.4
That means that the correlation between the height and weight is a positive weak correlation.
The function is invertible on either side of the vertex. There are many possible answers. Ones that include the vertex are ...
x ≥ 3
or
x ≤ 3
Answer:
She could out 20 necklaces and 20 bracelets on display and she would make $600.
Step-by-step explanation:
$18 necklaces x 20= $360
$12 bracelets x 20 = $240
totalling $600
The first card's probability is easy to calculate.
Of the 52 cards, 26 are black, so the probability is
(26 out of 52) or (1 out of 2) or .5
The second card will be drawn from 51 cards of which 25 are black:
25 / 51
Continuing with this pattern, drawing the 3rd card, the probability is
24 / 50
For the 4th card 23 / 49
For the 5th card 22 / 48
For the 6th card 21 / 47
So, to get the probability of drawing all six cards AND getting all black, we multiply these 6 fractions:
probability = (26 / 52) * (25 / 51) * (24 / 50) * (23 / 49) * (22 / 48) * (21 / 47)
