Psychologist is measuring learning in mice. He assumes that a mouse learns to recognize a specific object after a random number
Sphinxa [80]

Answer:

Option B) 0.2143                                            

Step-by-step explanation:

We are given the following in the question:

Numbers of exposures(x): 4,3,7

We have to find the maximum likelihood estimate of p.

Formula:

\hat{p} = \dfrac{n}{\sum x_i}

Putting the values, we get,

\hat{p} = \dfrac{3}{3+4+7} = \dfrac{3}{14} = 0.2143

Thus, the correct answer is

Option B) 0.2143

Using the quadratic formula to solve 5x=6x squared -3, what are the values of x?
kiruha [24]
Answer: 5+sqrt(97)/12, 5-sqrt(97)/12 or we write it as [5+/-sqrt(97)]/(12)

5x=6x^2-3

6x^2-5x-3=0

x=-b+/-sqrt(b^2-4ac)/2a

x=-(-5)+/-sqrt((-5^2-4(6)(-3))/2(6)

x= 5+/-sqrt(97)/12

And decimal form is;

x=1.237, -0.4041

If anyone has any questions please feel free to ask and I’ll reply ASAP. Thanks

Need help with this question please

We can use the two point form to find the answer:
y1 - y2 = m(x1 - x2)
Where y1 is the y coordinate(coordinate on the right hand side of (-9)) of the of the first coordinates, and y2 is the y coordinates of the second coordinates given (0).

While x1(-9) and x2(-6) are the x-coordinates(left hand side of the coordinates) of the coordinates given seperately.

m is the slope of the two points, and the formula is:
\frac{y1 - y2}{x1 - x2}
In this case:
\frac{ - 9 - ( 0)}{ - 9 - (-6)} \\ = \frac{ - 9 }{ - 9 + 6 } \\ = \frac{ - 9}{ -3 } \\ = 3

We can then proceed to find the eqaution by putting *one* of the points into the two-point formula.

Put (-6,0) into the formula:
-0-y = 3(-6-x)
-y = -18 - 3x
y = -(-18 - 3x)
y = 18 + 3x

Therefore the answer is y= 18+3x.

Hope it helps!
