Answer:
36 people
Step-by-step explanation:
The expected value E(X) = mean of sample = np
Where, p = population proportion, p = 9% = 0.09
n = sample size, = 400
The mean of the number of people with genetic mutation, E(X) = np = (400 * 0.09) = 36
36 people
Answer:
A coefficient is a number in front of a variable. For example, in the expression x 2-10x+25, the coefficient of the x 2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.
Step-by-step explanation:
Answer/Step-by-step explanation:
It typically takes teachers 9 minutes longer than students to get ready for school. - The median of two data = Teachers 25 - Students 16: typically, teachers take 25 mins to get ready and students take 16 mins to get ready.
Answer: x = 3. the length of side ST is 14.
Step-by-step explanation:
Since both sides are equal, we can use the equation 3x + 5 = 5x - 1.
To start the problem, we subtract 3x from each side which makes our equation 5 = 2x - 1.
The next step would be to simplify the equation by adding 1 to each side which makes our equation 6 = 2x.
We then need to simplify the equation to x = 3.
This means the answer to 9 is x = 3.
For the next problem, since we already know the value of x, we substitute its value which in this case would be 3. This leaves us with an equation of 9 + 5, which equals 14.
This means the length of side ST is 14.
Answer:
d
Step-by-step explanation:
using the distance formula
d = 
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )
d = 
= 
= 
= 
= 
≈ 12.369
