A clinical test on humans of a new drug is normally done in three phases. Phase I is conducted with a relatively small number of

healthy volunteers. For​ example, a phase I test of a specific drug involved only 7 subjects. Assume that we want to treat 7 healthy humans with this new drug and we have 11 suitable volunteers available. Complete parts​ (a) through​ (c) below.a. If the subjects are selected and treated in sequence, so that the trial is discontinued if anyone displays adverse effects, how many different sequential arrangement are possible if 7 people are selected from the 9 that are available? Choose the correct answer below. A. 181,440 B. 362,880 C. 5,040 D. 36b. If 7 subjects are selected from the 9 that are available, and the 7 selected subjects are all treated at the same time, how many different treatment groups are possible? There are_________ different treatment groups possible c. If 7 subjects are randomly selected and treated at the same time, what is the probability of selecting the 7 youngest subjects? P(selecting the 7 youngest subjects)_________(Type an integer or a simplified fraction.)

the trinomial x2 bx c factors to (x m)(x n). if b is negative and c is positive, what must be true about m and n?
galina1969 [7]

For c to be positive, and for b to be negative, m must be negative and n must be negative.


X^2 - bx + c = (x - m)(x - n).

c is the product of m and n. If both m and n are positive, c would be positive. However b is the sum of m and n, therefore to make b negative, both m and n must be negative to ensure that the product of m and n is positive

If trapezoid JKLM with vertices) (3, 4), K (6,4), L (8, 1) and M (1,1) is rotated 270 degrees counterclockwise, what are the
Stels [109]

Answer:

J' = (4,-3)

Step-by-step explanation:

Given

J = (3, 4)

K =(6,4)

L = (8, 1)

M = (1,1)

Rotation = 270CCW

Required

Determine the new coordinate of J

From rules of rotation,

When a point (x,y) is rotated 270 degrees CCW;

The new point becomes (y,-x)

Considering point J

J = (3, 4)

This means

(x,y) = (3,4)

Where x = 3 and y = 4

Using the above rotation rule of

(x,y) -> (y,-x)

The coordinates of J' becomes

J' = (4,-3)

Let the sample space be S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Suppose the outcomes are equally likely. Compute the probability of
Crazy boy [7]

Answer:

The probability is 3/5

Step-by-step explanation:

Given,

Sample space, S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10},

⇒ n(S) = 10,

Odd numbers less than 7 = 1, 2, 3, 4, 5 and 6

i.e. E = {1, 2, 3, 4, 5, 6}

⇒ n(E) = 6,

\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}

So, the probability of the event E,

P(E) =\frac{n(E)}{n(S)}

=\frac{6}{10}

=\frac{3}{5}
