Answer:
Hello!
16
Step-by-step explanation:
Because
-5+16=11
Answer:
b. Not binomial: there are more than two outcomes for each trial.
Step-by-step explanation:
Binomial probability distribution:
We need
Fixed number of trials.
Independent trials.
Each trial can be reduced to a yes/no proposition.
Rolling a single "loaded die 19 times, keeping track of the numbers that are rolled.
There are six possible outcomes(1,2,3,4,5,6), so cannot be reduced to a yes/no proposition, and the answer is given by option b.
Answer:
X = 9.2
Step-by-step explanation:
You have to use the pythagorean theorm, which is a squared + b squared = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.
6squared + 7squared = c squared
85 = csquared
Take the square root of both sides to get rid of the squared on the c.
sqroot of 85 = 9.2
Multiple the length and the width to find the area. 5.5 x 4.5 = 24.75. Then you do the same to the tile. 1 x 1 = 1. So each tile has an area of 1ft and we need to find how many tile we need to have to fill the 23.75 area of the rectangular room. 24.75/1 = 24.75
He will need 24.75 tile
