If a fair coin is tossed 4 times, what is the probability, to the nearest thousandth, of getting exactly 3 tails?
Answer:
000.3
Step-by-step explanation:
The probability of getting exactly 3 tails is 0.25 If a fair coin is tossed 4 times, what is the probability.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a coin if it is tossed 4 times.
Then the probability of getting exactly 3 tails is:
[tex]=\rm 4 C_3(\frac{1}{2} )^3\times (1-\frac{1}{2} )^1[/tex]
[tex]=\rm 4\times \frac{1}{16}[/tex]
= 1/4
= 0.25
Thus, the probability of getting exactly 3 tails is 0.25 If a fair coin is tossed 4 times, what is the probability.

Kim rolls a dice and flips a coin.
a) Calculate the probability that she
gets a 2 and a head.
b) Work out the probability that she
gets an even number and a tail.
What would b be
Answer:
a) 1 / 12
b) 1 / 4
Step-by-step explanation:
The events are independent since they do not affect each other. The total probability of two independent events is the product of the probabilities of the two events.
a) When rolling a die, there are 6 outcomes, the numbers 1 - 6. There is only 1 outcome where you can get a 2. Therefore, the probability of rolling a two is 1/6.
When flipping a coin, there are two ways it can land: heads or tails. And there is one outcome with heads. The probability of getting head would be 1 / 2.
To find the the total, you multiply the probabilities of the two events: 1 / 6 * 1 / 2 = 1 / 12
b) As stated before, when rolling a die, there are 6 outcomes, the numbers 1 - 6. There are 3 outcomes where she can roll an even number: the numbers 2, 4, or 6. So, the probability of rolling an even number is 3 / 6 or 1 / 2.
When flipping a coin, there are two ways it can land: heads or tails. And there is one outcome with tails. The probability of getting tails would be 1 / 2.
Now, you multiply the two probabilities to get the total probability: 1 / 2 * 1 / 2 = 1 / 4
The angle of elevation to the top of the Empire State Building in New York is found to be 11° from the ground at a distance of 5281 feet from the base of the building. Using this information, find the height of the Empire State Building in feet. Use the dimensions given in the diagram to give an equation and solve. Round two decimal places.
Answer:
The height of the building is of 1026.52 feet.
Step-by-step explanation:
This situation is modeled by a right triangle, in which the length of the opposite side to the angle of 11º is the height of the building, while the length of the adjacent side is of 5281 feet.
Tangent:
In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
In this question:
[tex]\tan{(11)} = \frac{x}{5281}[/tex]
[tex]x = 5281*\tan{(11)}[/tex]
Using a calculator, we have that the tangent of 11 degrees is: 0.1944. Thus:
[tex]x = 5281*\tan{(11)} = 5281*0.1944 = 1026.52[/tex]
The height of the building is of 1026.52 feet.

find the value of x in the polygon
x equals to 10.............
A. 15
B. 75
C. 100
D. 105
Answer:
B. 75
Step-by-step explanation:
According to vertical angles theorem, angles that are opposite of one another with shared lines will be equal, so we can set 5x = x +60.
Solving for x, we get x = 15, and substituting into the angle we get 15 + 60 = 75 degrees.

(5a + 18) + (48 - a) + (8a - 30) = 180
5a + 18 + 48 - a + 8a - 30 = 180
5a - a + 8a + 18 + 48 - 30 = 180
12a + 36 = 180
12a = 180 - 36
12a = 144
a = 12

PLEASE HELP !! ILL GIVE BRAINLIEST TO THE RIGHT ANSWERS.
Answer:
12
Step-by-step explanation:
Use the pythagorean theorem ([tex]a^2+b^2=c^2[/tex]). A and b are the two legs of the triangle, and c is ALWAYS the hypotenuse. Plug in the values for a and c
[tex]a^2+b^2=c^2[/tex]
[tex]5^2+b^2=13^2[/tex]
[tex]25+b^2=169[/tex]
[tex]b^2=144[/tex]
[tex]b=12[/tex]
Answer:
b = 12m
Step-by-step explanation:
5^2 + b^2 = 13^2
25 + b^2 = 169 --> *subtract 25 form both sides*
b^2 = 144 --> find square root of 144*
b = 12

Which ordered pair best describes the point plotted in Quadrant II on the coordinate plane shown?
A. (-4, 6 )
B. (6, 4 )
C. (4, -6)
D. (6, -4 )
Answer:
A. (-4, 6 )
Step-by-step explanation:
Signals of x and y in each quadrant:
Suppose we have a point P(x,y).
In the first quadrant, we have that both are positive, that is, x > 0, y > 0.
In the second quadrant, x is negative, while y is positive, that is, x < 0, y > 0.
In the third quadrant, both are negative, that is, x < 0, y < 0.
In the fourth quadrant, x is positive while y is negative, that is, x > 0, y < 0.
In this question:
In the second quadrant, we have x negative and y positive, so the ordered pair that best describes is given by option A.
There are 4 consecutive integers that sum to 394. What is the least of these integers?
Answer: 97
Step-by-step explanation:
394 / 4 = 98.5, so the 4 numbers must be around 98.5.
97 + 98 + 99 + 100 = 394

Answer:
392
Step-by-step explanation:
I would separate this into 2 shapes a triangle and a square. So first take the area of the square
area of square = base x height
16x19=304
Than take the area of the triangle
area of triangle = 1/2(base x height)
you can find the height of the triangle by subtracting 19 from 30 which is 11, and the base is the same as the base of the square which is 16
1/2(16x11)= 88
Add them together
304+88=392

what is the value of x ?
Answer:
x = 19
Step-by-step explanation:
The two angles form a right angle
A right angle has a measure of 90 degrees
Thus, x + 14 + 3x = 90
^This is the equation we will use to solve for x
x + 14 + 3x = 90
step 1 combine like terms
x + 3x = 4x
we now have 4x + 14 = 90
step 2 subtract 14 from each side
90 - 14 = 76
14 - 14 cancels out
we now have 76 = 4x
step 3 divide each side by 4
4x / 4 = x
76 / 4 = 19
we're left with x = 19

Can you help me. 12.95 + 0.4 + 0.3 + 0.09 = ?
Answer:
13.74
Step-by-step explanation:
Answer:
13.74
Step-by-step explanation:
Add 0.4+0.3 = 0.7, so the equation now looks like this: 12.95+0.7+0.09
Add 0.7 + 0.09 = 0.79, so the equation now looks like this: 12.95 + 0.79
Add 12.95 + 0.79, so now you are left with: 13.74
