Assume that hybridization experiments are conducted with peas having the property that for offspring, there is a 0.75 probabilit

Verdich [7]

Answer:

a) Standard Deviation = 2.74

b) Significantly Low = values below 24.52 (or equal)

Significantly High = values above 35.48 (or equal)

Step-by-step explanation:

This is binomial probability distribution problem.

Where n = 40 [groups of 40, total trials]

p = 0.75 [probability of success]

The formula for standard deviation is:

$Standard \ Deviation = \sqrt{np(1-p)}$

We know n = 40 and p = 0.75, so the standard deviation is:

$Standard \ Deviation = \sqrt{np(1-p)} \\Standard \ Deviation = \sqrt{(40)(0.75)(1-0.75)}\\ Standard \ Deviation = 2.74$

the range rule of thumb tells us that usual range of values is within 2 standard deviation of the mean. First let's calculate mean.

We know,

Mean = n * p = 40 * 0.75 = 30

Mean - 2* Standard Deviation = 30 - 2(2.74) = 24.52

and

Mean + 2* Standard Deviation = 30 + 2(2.74) = 35.48

Significantly Low = values below 24.52 (or equal)

Significantly High = values above 35.48 (or equal)

Find an equation of the parabola with focus (2, −3) and directrix y = 1.

Likurg_2 [28]

Answer:

Step-by-step explanation:

The correct option is option (C).

The required equation of the parabola is

Step-by-step explanation:

Formula:

The distance of a point (x₁,y₁) from a line ax+by+c=0 is

The distance between two points (x₁,y₁) and (x₂,y₂) is

Given that, the focus of the parabola is (2,3) and directrix y= - 1.

We know that, a parabola is the locus of points that equidistant from the directrix and the focus.

Let any point on the parabola be P(x,y) .

The distance of P from the directrix is

=y+1

The distance of the point P from the focus (2,3) is

According to the problem,

The required equation of the parabola is

Find the exact value of the following expression (without using a calculator): tan(Sin^-1 x/2)

Sati [7]

Answer:

tan(Sin^-1 x/2)= $\frac{x/2}{\sqrt{1-x^{2}/4 } }$

Step-by-step explanation:

Let sin^-1 x/2= θ

then sinθ= x/2

on the basis of unit circle, we have a triangle with hypotenuse of length 1, one side of length x/2 and opposite angle of θ.

tan(Sin^-1 x/2) = tanθ

tanθ= sinθ/cosθ

as per trigonometric identities cosθ= √(1-sin^2θ)

tanθ= sinθ/ √(1-sin^2θ)

substituting the value sinθ=x/2 in the above equation

tanθ= $\frac{x/2}{\sqrt{1-x^{2}/4 } }$

now substituting the value sin^-1 x/2= θ in above equation

tan(sin^-1 x/2) = $\frac{x/2}{\sqrt{1-x^{2}/4 } }$
