Answer:
a) 30% probability that it will not be colder today than it was yesterday
b) 90% probability that it will not be warmer today than it was yesterday
Step-by-step explanation:
In this question, we have that:
0.1 = 10% probability it will be warmer today than yesterday.
0.7 = 70% probability it will be colder today than yesterday.
a .What is the probability that it will not be colder today than it was yesterday?
70% probability it will be colder, so 100 - 70 = 30% probability that it will not be colder today than it was yesterday.
b What is the probability that it will not be warmer today than it was yesterday?
10% probability it will be warmer today than yesterday, so 100 - 10 = 90% probability that it will not be warmer today than it was yesterday
Answer:
the last on bottom right :)
Step-by-step explanation:
Answer: x1 = -2, x2 = 3/4
Step-by-step explanation:
4x^2 + 5x -6 = 0
4x^2 + 8x -3x -6 = 0
4x(x+2)-3(x+2)=0
(x+2)(4x-3) = 0
x+2 = 0: x = -2
4x-3 = 0: x = 3/4
I hope this helps you
width w
length 3w
Perimeter=2. (width + length )
Perimeter=2 (w+3w)
24=2.4w
w=3
3w=3.3=9
