Answer:

b. Yes, probability is > 0.05

Step-by-step explanation:

We have to find P(X=3) and if the probability is below 0.05 then the it would be unusual and if it isn't below 0.05 we believe that the data from the blood program.

This probability can be found bu binomial distribution  with parameters  n=6

and p=0.4.

P(X=x)=nCx(p^x)(q^n-x)

where q=1-p=1-0.4=0.6.

P(X=3)=6C3(0.4^3)(0.6^3)

P(X=3)=20(0.064)(0.216)

P(X=3)=0.27648

As the probability that the three have a blood group is greater than 0.05, so,  we believe that the data from the blood program.

The weight of an object on the moon varies directly as its weight on earth. A person who weights 150.94lb on earth weighs 25.66l
Veronika [31]

109.93 lbs

since the quantities vary directly, then

w(moon) = kw(earth ) ← ( k is the constant of variation )

to find k use the given condition

k = w( moon ) / w( earth ) = \frac{25.66}{150.94}

given w(earth) = 218.24

w(moon) = \frac{25.66(218.24)}{150.94} = 109.93

Vertically stretched by a factor of 2, then translated<br> 4 units left and 1 unit down
drek231 [11]

A vertical stretch of scale factor 2, followed by a translation of 4 units left and 1 unit down is written as:

g(x) = 2*f(x + 4) - 1

<h3>How to write the given transformation?</h3>

For a general function f(x), a vertical stretch of scale factor K is written as:

g(x) = K*f(x).

<u><em>Horizontal translation:</em></u>

For a general function f(x), a horizontal translation of N units is written as:

g(x) = f(x + N).

  • If N is positive, the shift is to the left.
  • If N is negative, the shift is to the right.

<u><em>Vertical translation:</em></u>

For a general function f(x), a vertical translation of N units is written as:

g(x) = f(x) + N.

  • If N is positive, the shift is upwards.
  • If N is negative, the shift is downwards.

So, if we start with a function f(x) and we stretch it vertically with a scale factor of 2, we get:

g(x) = 2*f(x)

Then we translate it 4 units left:

g(x) = 2*f(x + 4)

Then we translate 1 unit down:

g(x) = 2*f(x + 4) - 1

This is the equation for the transformation.
