Active immunity can be natural or artificially developed. Naturally acquired - a person is exposed to a live pathogen, develops an immune response - and then creates memory T and B cells. Artificially acquired - a person is given a vaccine (which contains the antigen). This stimulates the same response, without the symptoms of the disease.

Answer:

The answer is B

Step-by-step explanation:

Eight minus three is five so 5/8.

HhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhGiven:
trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long 
⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in
⇒ 77inches by 105 inches
⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long
⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in
⇒ 160 inches by 92 inches
⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long
⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in
⇒ 66 inches by 148 inches
⇒ 9,768 square inches

130 square feet convert to square inches.
130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches
Perimeter = 2(160 + 117)
P = 2(277)
P = 554 inches
P = 2(277)
P = 554 inches 

Answer:

The probability is 0.152

Step-by-step explanation:

We know that in this town 39% of all voters are Democrats. Therefore, the probability of a randomly selected voter being a Democrat is

The experiment of randomly select voters for a survey is called a Bernoulli experiment (under some suppositions). We suppose that exist independence in this randomly selection of voters. We also suppose that there are only two possibilities for the voter : It is Democrat or not.

Now the variable X : ''The randomly selected voter for a survey is Democrat'' is a Binomial random variable.

X ~ Bi (n,p)

The probability function for the BInomial random variable X is :

Where ''n'' is the number of Bernoulli experiments (In this case n = 2 because we randomly selected two voters)

P(X=x) is the probability of the variable X to assumes the value x

(nCx) is the combinatorial number define as

p = 0.39 in this exercise.

We are looking for P(X=2) ⇒

If we round to the nearest thousandth the probability is 0.152

Answer : The mole fraction of the total ions in an aqueous solution is 0.0248

Explanation :

First we have to calculate the moles of water.

Now we have to calculate the moles of magnesium ion and bromide ion.

As we are given that 0.4 moles of that means, there are 0.4 moles of magnesium ion and 0.8 moles of bromide ions.

Total mole of ions in an aqueous solution = 0.4 + 0.8 = 1.2 mole

Now we have to calculate the mole fraction of the total ions in an aqueous solution.

Therefore, the mole fraction of the total ions in an aqueous solution is 0.0248

Answer: D is correct.

Explanation: At the time the Netherlands was a Spanish territory (Charles V inherited this territory from his ancestors, dukes of Burgundy) which brought quite a lot of money to Spain because Netherlands was the most  prosperous part of Spanish empire. The problem was the protestantism of Dutch, their unwillingness to get converted to Catholicism and obey Spanish Catholic mores and rules. The result of that ? Many rebellions of Dutch, disrespect toward Spanish power. Many Dutch found aid and support in England (in this respect English Chanel was crucial) and over the time there was sort of unwritten alliance between the Dutch and the English. And that was something Spaish crown wanted to stop. At the time Spain (house of Habsburg) was considered the most powerful of European countries.

Square root of 45 is 6.7082039325

The volume of a cube or box can be measured by multiplying its length, width, and height (length x width x height).

The units of measure for volume are cubic units, such as cubic centimeters.

V = pi*(r^2)*h
V = pi*(7^2)*5
V = pi*(49)*5
V = 245pi ft^2
V = 796.7 ft^2

You can cross multiply to find the answer. Start by setting up your equation:

45/30 = 60/x  (30 represents half an hour)
Next, cross multiply, 45 times x, and 60 times 30: 

45x = 1800  you must isolate the "x" value by using the opposite operation it is involved in. Here we have 45x (x is multiplied to 45) so we must divide 45, which will cancel itself out, leaving us with "x."

What you do on one side of the equation, you must do on the other, so divide 1800 by 45 as well, which will leave you with 40.

Working it out on paper, your equation should now look like this: x=40, which represents the amount of time it will take to fill a 60 gallon tube.

Answer: It will take 40 minutes to fill a 60 gallon tube. 

The binomial nomenclature for a human is Homo Sapiens. Binomial means two names, and nomenclature means to chose a name. Therefore the two word classification of a human being is homo sapiens. (It also means wise man)

If the voltage is constant (DC like a battery, not AC), there are only resistors in the circuit (not capacitors or inductors) and the resistance doesn't vary, then the current through any circuit is constant.

Answer:

Option: Invasion by the Soviet Union.

Explanation:

The Soviet Union invaded Afghanistan in 1979. Afghan government need for help from soviet to fight against the mujaheddin rebels was the reason for their invasion. The Soviet occupancy in Afghanistan ended in 1989. Eventually, the Soviet Union ended in on 26 December 1991 and replaced by Russian Federation.

Triangle ABC is congruent to triangle YXZ. How do I know this?
 Look at the angles and adjacent (bottom) line.
Because Angle A and Angle Y are both equal to (what I believe says) 78 degrees, they are equal. 
Next, Angle B is equal to Angle X because it is the angle that connects the adjacent (bottom) line and the hypotenuse (top line). Even though they have no measurements or tick marks, it's the process of elimination.
Finally, Angle C and Angle Z. We know that these are equal do to their degree similarity of (what I think is) 65.

{B} Triangle ABC is congruent to Triangle RSQ. How do I know this?
Because Angle A is congruent to the only other angle there, Angle R.
Next, B and S are congruent. If you think of them as angles, then you can see that "angle" b is connected to the leg of AB and BC. AC has one tick mark, as does RS. BC has no tick or anything to note it's congruence. So because Point be is stick in between a leg with one tick and one leg with no tick, look for the similarity in triangle RSQ. The similarity showing as S. You should understand enough now to know how I got how C and P are congruent.
