What is X^2-X=0? It's factoring equations, but i'm not sure how to factor x-x=0, and then put it into curly brackets.
luda_lava [24]
Here are the solutions:
X^2 - X = 0
Factor out X
X(X - 1) = 0
Here are 2 solutions
X = 0 and X - 1 = 0, which is the same as X = 1.

The solutions are:
X = 0
X = 1.

A researcher reports a 98% confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be [0.34,
Fantom [35]

Answer:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Step-by-step explanation:

For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Solving this for x kx+c=2
KIM [24]
Kx + c = 2
Subtract c from both sides:-
kx + c - c = 2 - c
kx = 2 - c
x = (2 - c) / k
