Answer:
B
Step-by-step explanation:
We can use the standard form of an exponential function:
The point (0, 18) tells us that <em>y</em> = 18 when <em>x</em> = 0. Hence:
Simplify:
Our equation is now:
Next, the point (-1, 15) tells us that <em>y</em> = 15 when <em>x</em> = -1. Hence:
Isolate the variable:
Hence:
By substitution:
Our answer is B.
Answer:
9 and 10
Step-by-step explanation:
How you find the area of a triangle is base × height ÷ 2. So the equation would be 6×3=18 18÷2=9, so the answer is 9. Hope this helped!
Answer:
Step-by-step explanation:
Let's call p the probability that a passenger shows up.
Then we know that:
Then we took a sample of n = 6 passengers.
We can calculate the probability that less than 4 are presented using the binomial formula:
Where x is the number of passengers that show up, n is the number of selected passengers, p is the probability that a passenger shows up.
Then we look for:
The inverse is x²+7
