Answer:
Pr(all will survive in one year) = 0.35 to 2 decimal places
Pr(at least 8 will survive) = 0.39 to 2 decimal places.
Step-by-step explanation:
Probability of a tree surviving one year is 0.9. While not surviving probability is 1 - 0.9 = 0.1
This is obtained from the 90℅ surviving rate for one year planted by the landscaping firm.
Probability that if 10 trees are planted, all will survive for one year is:
0.9x0.9x0.9x0.9x0.9x0.9x0.9x0.9x0.9x0.9 = 0.9^10 = 0.349
Probability that at least 8 will survive in one year can be expressed as
8 survived x 2 not survived +(or) 9 survived x 1 not survived +(or) 10 survived
= [(0.9^8)x(0.1^2) + (0.9^9)x(0.1^1) + (0.9^10)] = 0.391
Step-by-step explanation:
Answer:
step by step Explanation:
Since this is a right triangle,
We can find the length b by using the Pythagoras theorem
a2+b2=c2
Plugin the values
→22+b2=62
→4+b2=36
→b2=32
Take the square root of both sides
→√b2=√32
→b=√16⋅2
⇒b=4√2
The fraction for the above ratio is 5/9
Where 5- no of cups of bread crumbs needed; 9= pounds of ground beef needed
Step-by-step explanation:
Anything that can be represented in the x/y form constitutes the fraction.
The above statement can be represented in the fraction form as 5/9. It means that for every 9 pounds of ground beef, 5 cups of bread crumbs are needed.
The above fraction provides the ratio in the form of cups of bread crumb/ pound of ground beef required. Where 5 represents the number of cups of bread crumbs required, 9 represents the pound of ground beef needed for the same.
