This is the expression simplified:
A=1/2 b*h
So substitute it in 1/2*1/2*4
1/2*1/2= 1/4
1/4*4= 4/4= 1 so the entrance is 1 foot tall
Answer: 79%
That’s because it’s the middle probability it can’t be others because they are too high it too low
Answer:
The answer is "
"
Step-by-step explanation:






Eight phenotypes were present.
Df is provided also by a number of phenotypes -1 The degree of freedom

For p-value 0,9, Chi-square is 2.83;
The p-value of 0.75 is 4.5. Chi-square
Chi-sqaure value is observed at 2.965.
That means 0.90>p-value>0.75.
Option c : 9 is the answer.
Explanation:
The expression is 
We need to determine the subtracted value of the expression.
From the expression we can see that the expression contains two negative signs.
To simplify the expression, we know that, When we multiply two negative numbers then the product is always positive.
This means 
Thus, the expression can be written as

Adding the two numbers, we get,

Thus, the value of the expression is 9.
Hence, Option c is the correct answer.
