Im not entirely sure what the scale factor is, but i do know that 10 ft is 20 times bigger than 6in, 4 cm is 16 times bigger than 2.5mm, and that 15 yards is 9times bigger than 5ft. If that helps at all
Answer:
(a) 0.42
(b) 0.28
(c) 0.88
Step-by-step explanation:
Let probability that the bank stock will appreciate over a year, P(A) = 0.70
Probability that the electric utility will increase over the same period, P(B) = 0.60
Also, it is given that the two events are independent.
(a) Probability that both stocks appreciate during the period = Bank stock will appreciate * Electric utility will appreciate = P(A) * P(B)
= 0.70 * 0.60 = 0.42 .
(b) Probability that the bank stock appreciates but the utility does not is given by;
P(A) * (1 - P(B)) = 0.70 * (1 - 0.60) = 0.70 * 0.40 = 0.28 .
(c) Probability that at least one of the stocks appreciates = P(A B)
P(A B) = P(A) + P(B) - P(A B)
= 0.70 + 0.60 - (0.70 * 0.60) { because both events are
independent }
= 1.3 - 0.42 = 0.88 .
Answer:
median
Step-by-step explanation:
The centre of every data set is the second quartile/50th percentile/median
I also think it is c. Just look over and make sure or your positive that i am right
Answer:
10 units long
Step-by-step explanation:
We need to find the distance from the origin (0, 0) to the point (-3, -4), that will be a radius of the circle.
Use the distance formula: d = √[(x2 - x1)² + (y2 - y1)²]
Plug in the values from the 2 points we are given...
d = √[(-3 - 0)² + (-4 - 0)²]
d = √[(-3)² + (-4)²]
d = √[ 9 + 16 ]
d = √25
d = 5
The radius is 5, therefore the diameter is 10. (the diameter is always twice the length of the radius)
