Answer:
75%
Step-by-step explanation:
Probability of a day being sunny (P(S)) = 0.9
Probability of driving when sunny (P(Ds)) = 1-0.75 = 0.25
Probability of a day NOT being sunny (P(N) = 1- 0.9 = 0.1
Probability of driving when sunny (P(Dn)) = 1-0.25 = 0.75
The probability of a day being sunny given that the person is driving (S) is defined as the ratio between the probability of the person driving and the day being sunny by the probability of the person driving:
There is a 75% probability that it's a sunny day.
Answer:
56
Step-by-step explanation:
5ft x 4ft = 20ft / 2 = area =10 10 x 4 triangles = 10 x 4 = 40 + square= area, so 4 x 4 = 16 + 40 = 56ft
Hope this helps!
Brett cannot spend more than $30, so the cost of the books and the shipping charge have to be less or equal to $30, we can express this as in an inequality, like this:
Where n is the number of books purchased, since each book costs $4, 4 times n equals the total cost of the books and 2 is the shipping charge. We can solve for n in the inequality like this:
Then, brett can afford no more than 7 books.

Answer: 180cm
Explanation:
The area of a triangle is 1/2(b)(h).
The height of the triangles is 12cm and the base is 6cm.
1/2(6)(12) = 36cm
Multiply by 4 = 144
For square: 6 • 6 = 36cm
144cm + 36cm = 180cm
