Answer:
0.11069
Step-by-step explanation:
We will assume that the trains pass by his house following a uniform distribution with values between 0 and 24. The probability of a train passing on a 9-hour time period is 9/24 = 3/8 = 0.375. Lets call Y the amount of trains passing by his house during that 9-hour period. Y follows a Binomail distribution with parameters 22 and 0.375.
P(Y ≤ 5) = P(Y = 0) + P(Y=1) + P(Y=2) + P(Y=3) + P(Y=4) + P(Y=5) =
I hope that works for you!
Question is not proper, Proper question is given below;
For a birthday party, Mr. Perkins orders 8 chocolate chip cookies and 16 sugar cookies. Each cookie is the same price. He also picks up a cupcake for himself, which costs $2.75. The total bill is $44.03. What is the cost of a cookie?
Answer:
The Cost of the cookie will be $1.72.
Step-by-step explanation:
Given:
Mr Perkins orders 8 chocolate chip cookies and 16 sugar cookies.
Since cost of both the cookies are same then Let us assume the cost of cookies be 'x'.
Total cost of the cookies =
Cost of Cup cakes = $2.75.
Total bill he pays = $44.03
We need to find the cost of each cookies.
Now we know that Total bill he pays is equal to sum of Cost of cookies and Cost of Cup cakes he bought.
Framing in equation form we get;
Now Subtracting both side by 2.75 using Subtraction property we get;
Now Dividing both side by 24 using Division property we get;
Hence The Cost of the cookie will be $1.72.
Answer: y=1/x is the blue line and it goes straight up and down the y and x axis.
y=x^2 is the green line which is a thin "u" like shape. its going up the y axis.
y=\frac{x^{3}}{x^{2}-9} is the red line it goes up and down the y axis and diagonally across the middle of both axis'.
Step-by-step explanation: I went to desmos calculator and typed in your equation and it automatically gave me this graph. (See Picture for more details.)
