Answer:
Approximately 3 bunches would equal $4.50. So you should be able to buy at least 4 bunches which would be 10 pounds
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:
Given:
The point is (-5,7).
To find:
The image of the given point after 90 degrees counter clockwise rotation.
Solution:
If a point rotated 90 degrees counter clockwise, then
Let the given point is P(-5,7). Using the above rule, we get
Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).

y = 0.2·0.5^x
The form of an exponential function is ...
y = a·b^x
If you look at the values of this for x=0 and x=1, you find ...
<u>For x=0</u>
y = a·b^0 = a·1 = a
The table tells us the corresponding value of y is 0.2, so ...
a = 0.2
<u>For x=1</u>
y = a·b^1 = ab
For the given value of a and the table value of y for x=1, we have ...
0.1 = 0.2·b
b = 0.1/0.2 = 1/2 = 0.5
Then the exponential function that describes the table is ...
