Step-by-step explanation:
P(A) = 0.47
P(B) = 0.53
P(A|B) = 0.57
a. Probability that at least one stock will rise is equal to P(A u B)
= P(A) + p(B) - P(A n B)
= (O.47+0.53)-(0.53*0.57)
= 1-0.3021
= 0.6979
b. Events A and B are not mutually exclusive. This is because P(AnB)≠0
P(AnB) = p(B).P(A|B)
= 0.53x0.57
= 0.3021 and this value is not equal to 0
c. No, events A and B are not independent. This is because P(A|B) ≠ P(A)
Since we have
p(A) as 0.47
P(A|B) as 0.53
Answer:
The area of each section of the circle is
Step-by-step explanation:
we know that
The area of a circle is equal to
we have
substitute
To find the area of each section divide the complete area of the circle by
so
Answer:
y = 5x - 472
Step-by-step explanation:
You have two data points: (108,68) and (114,98). Plot the points on a graph, with temperature on the x-axis and chirp rate on the y-axis.
Use the coordinates of the points to determine the slope of the line through them.
Δy =98-68 = 30
Δx =114-108 = 6
Slope = Δy/Δx = 5
Point-slope equation for line of slope 5 that passes through (114,98):
y-98 = 5(x-114)
To put the point-slope equation into slope-intercept form, rearrange to solve for y and simplify.
y = 5(x-114) + 98 = 5x - 472
I can’t see the top of the image. Can you make it more upper a little? I think it is 9
Put 2 together straight up then one over it side ways
