What is the probability that either two heads or three heads will be thrown if six fair coins are tossed at once?

Mathematics

lesantik [10]3 years ago
8 0

Answer:The right answer will be

0. 546875

Step-by-step explanation:

When 6 coins are tossed , the total number of outcomes is 2*2*2*2*2*2= 64

The number of ways of getting two heads are 6!/2!*4!=15.

The probability of getting two heads P(A) is 15/64 .

In the same way, the probability of getting three heads P( B) is 5/16.

Now, P(A)+P(B)= 0.546875

Answer:

  {x| x≤ 1/2 or x ≥ 3/4}

Step-by-step explanation:

The values of x that make the factors zero are 3/4 and 1/2. The product of these factors will be positive when both factors are negative (for x < 1/2) or when both factors are positive (x > 3/4). The matching answer selection is the third one.

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed
shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168  pounds

Patient's weight in kg =168\times 0.453592=76.203456  kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = 0.4 \times 76.2035\ mg = 30.4814\ mg

We know,  1 micro gram = 0.001 mg

Concentration of drug is given by,

500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

d= \frac{30.4814}{0.5} = 60.9628

Therefore, We inject 60.9628 milliliters of dosage.

Whats the y intercept in 4x-2y=8
MaRussiya [10]

Answer:

Y-intercept=-4

Step-by-step explanation:

When you are finding the y intercept of something, you cover up the other variable because you would insert zero. In this case, x would be 0 and it will leave you with the equation, -2y=8 Just solve the rest using algebra--

-2y=8

-y=4

y=-4

So that means that the y intercept would be -4

I hope this helps!!

Let me know if you have other questions!
