Answer:

4.5 mL

Step-by-step explanation:

Amount of Acetaminophen prescribed is 15 mg/kg. This means for every 1 kg of the child's weight, 15 mg of Acetaminophen will be administered to the child.

Weight of the child = 9.6 kg

Since, for each 1 kg the amount of Acetaminophen is 15 mg, the amount of Acetaminophen needed for 9.6 kg will be = 9.6 x 15 = 144 mg

Therefore, the child must be administered 144 mg of Acetaminophen in total.

The strength of Acetaminophen is 160mg / 5 mL. This means 5 mL of an injection contains 160 mg of Acetaminophen. But since, the child needs 144 mg, we need to calculate in mL, the volume of injection needed for 144 mg of Acetaminophen.

160 mg of Acetaminophen is present in an injection of volume = 5mL

1 mg of Acetaminophen is present in an injection of volume = $\frac{5}{160}$ mL

144 mg of Acetaminophen is present in an injection of volume = $\frac{5}{160} \times 144 = 4.5$ mL

Thus, 4.5 mL of the injection will contain 144mg of Acetaminophen which would be administered to the patient.

Answer:

A) It fulfills the condition of binomial experiment

B) P (x=12) =0.1678

C)P ( x ≥16)= 0.1011

d) P (x>17) =0.0096 < 0.5

Step-by-step explanation:

A. The binomial probability distribution has the following four properties

1. the outcomes of each trial maybe classified into success and failure.

2) the probability of success p remains constant for all trials.

3) the successive trials are all independent.

4) the experiment is repeated a fixed number of times ,n.

These all conditions are fulfilled by the given question so it is a binomial experiment.

B) P (x=12) = 20C12 (0.64)^12 * (1-0.64)^8= 0.1678

C) P ( x ≥16) = P (x=16) + P (x=17) + P (x=18) + P (x=19)+ P (x=20)

where

P (x=16)= 20C16 (0.64)^16 * (1-0.64)^4= 0.0645

P (x=17)= 20C17 (0.64)^17 * (1-0.64)^3= 0.0270

P (x=18)= 20C18 (0.64)^18 * (1-0.64)^2= 0.0080

P (x=19)=20C19 (0.64)^10 * (1-0.64)^1= 0.0015

P (x=20)= 20C20 (0.64)^20 * (1-0.64)^0= 0.0001

P ( x ≥16)= 0.0645+ 0.0270 +0.0080+ 0.0015+0.0001= 0.1011

d) P (x>17)= P (x=17) + P (x=18) + P (x=19)+ P (x=20)

=0.0270 +0.0080+ 0.0015+0.0001

=0.0096

From this we see that the probability of more than 17 people who flush public toilets with their foot is unusual because it is far away from the mean which is supposed to be somewhere 0.5 in a given distribution.

Nikitich [7]

I'd like to assume that the triangle is a right triangle and you solve for x so...

133 + c = 180 (supplementary property to find one angle of triangle)
c = 47

x = 180 - 90 - 47 (int. angles of triangle = 180)
= 90 - 47
= 43

Therefore, x is 43 degrees

Answer:

F, I only

Step-by-step explanation:

We can see this is a quadratic equation and c is the constant. What changes when we change the constant? It will change the h intercept which we can see is also known as a y intercept (the y axis is renamed as h).

You can also use graphs to visualize this, try changing the constant in the equation and you can see the y intercept change.

so the answer is F, I only.
