What are independent and dependent variables?

1 answer:

8 0

I'm pretty sure this doesn't belong in mathematics but this belongs to science. Anyways.. an independent variable is the only variable that is being changed. The dependent variable is what you find out- in other words it is the outcome.

Suppose that 0.10 of population is colourblind if 25of sample drown from this population find probability that at least 7 have c

Leokris [45]

Answer:

$P(X \geq 8)=22*10^{-4}$

Step-by-step explanation:

From The Question we are told that

Prob that population is colourblind $P(C)=0.10$

Sample size $N=25$

Generally the equation for Number of color blinds is mathematically given by

$P(X \geq 8)=\sum^{25}_{x=8}(25..x)(0.10)^x(0.90)^25-x$

$P(X \geq 8)=22*10^{-4}$

Given the equation Y -3 equals 1/2 (X +6 )in point slope form identify the equation of the same line in standard form

liberstina [14]

The standard form of a line:

$Ax+By=C$

We have the equation of a line in the slope-point form:

$y-3=\dfrac{1}{2}(x+6)$ use distributive property

$y-3=\dfrac{1}{2}x+3$ add 3 to both sides

$y=\dfrac{1}{2}x+6$ multiply both sides by 2

$2y=x+12$ subtract x from both sides

$-x+2y=12$ change the signs

$x-2y=-12$
