The probability of getting exactly 4 tails when tossing 16 coins simultaneously is approximately 0.385 or 38.5%.

In order to calculate the probability of getting a specific number of tails when tossing multiple coins, we can use the binomial probability formula.

In this case, you want to calculate the probability of getting 4 tails out of 16 coins. Plugging the values into the formula:

P(X = 4) = (¹⁶C₄) * (0.5₄) * (0.5¹²))

Calculating the values:

P(X = 4) = (16! / (4! * (16-4)!)) * (0.5⁴) * (0.5¹²)

= (16! / (4! * 12!)) * (0.5⁴) * (0.5¹²)

= (16 * 15 * 14 * 13) / (4 * 3 * 2 * 1) * (0.5⁴) * (0.5¹²)

≈ 0.385

Therefore, the probability of getting exactly 4 tails when tossing 16 coins simultaneously is approximately 0.385 or 38.5%.

Step-by-step explanation:

The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

There are 420 rabbits in the park.

Given that, on Monday 20 rabbits were tagged on Tuesday 12 out of 42 rabbits were found tagged,

So,

Tuesday = 12 / 42 = 2/7

2/7 of the total rabbits on the farm = 20 tagged on Monday

Let r represent the total rabbits on the farm

then (2/7)r = 20

r = 120(7/2)

r ≈ 420

Hence, there are 420 rabbits in the park.

Answer: 278 tickets.

Step-by-step explanation: Each ticket costs $2.25, and is sold as that constant rate. We know that the drawer ended with 775.50 and started with a minimum of $150. Using this information, we can construct an equation.

150 + 2.25x = 775.50

Using algebra, we can simplify the equation to find the answer. Whatever we do to one side must be done to both sides.

150 + 2.25x = 775.50

-150                -150

= 2.25x = 665.50

(2.25 / 2.25) x = (665.50 / 2.25)

= x = 278

Answer: x= 6

Step-by-step explanation:

Since the shape is a parallelogram, the angles will either be equal to each other or add up to 180.  

You can see they do not look the same so they add up to equal 180

12x + 3 +105 = 180

12x + 108 = 180

12x = 72

x = 6

The exact value of the series ∑n=0infinitynπ^2n/(16^2n * (2n+1)!) is approximately -0.190985.

To find the exact value of the series, we need to evaluate each term and sum them up. Starting with the given expression, we have (-1)^n * π^(2n) / (16^(2n) * (2n+1)!). Breaking down each term, we have (-1)^n, π^(2n), 16^(2n), and (2n+1)!.

The term (-1)^n represents alternating signs, where it alternates between positive and negative for each value of n. The term π^(2n) represents π raised to the power of 2n. The term 16^(2n) represents 16 raised to the power of 2n. The term (2n+1)! represents the factorial of 2n+1.

By substituting the values of each term into the given expression and summing them up from n = 0 to infinity, we can approximate the value to be approximately -0.190985.

The cylinders formed by stacking circular coins on top of each other will not have the same volume if they are formed in different ways. In this case, the first stack forms a cylinder with a vertical axis, while the second stack forms an oblique cylinder with an axis that is not vertical.

The volume of a cylinder is given by the formula V = πr^2h, where r is the radius of the base and h is the height of the cylinder. Since both stacks have the same number of coins stacked on top of each other (h coins), the height of both cylinders will be the same. However, the radius of the base will be different for the two cylinders.

In the case of the first stack, the coins are stacked directly on top of each other to form a cylinder with a base that is perfectly circular. Therefore, the radius of the base is the same for every coin in the stack. This means that the radius of the base of the cylinder will be constant, and the volume of the cylinder will only depend on the height.

On the other hand, in the case of the second stack, the coins are not stacked directly on top of each other. Instead, they are arranged in a slanted manner, forming a base that is not perfectly circular. As a result, the radius of the base will vary depending on the position of the coin in the stack. This means that the volume of the oblique cylinder will depend on both the height and the varying radius of the base.

Therefore, the cylinders formed by the two separate stacks of circular coins will have different volumes due to the difference in the base shape and the varying radius of the base in the oblique cylinder.

if he needs 12 tins, and purchased from paint -O  mine, he would spend (12/3) X 7.50 = 4 x 7.50 = £30

from ready steady, he can buy 4 for £11. he needs 12.

so he will spend (12/4) X 11 = 3 X 11 = £33. but he can get 15% off. 15% off is the same as multiplying by 0.85.

First lets find out how many feet or in one yard ?

Well 1 yard = 3 feet.

Now that we know that we can use our knowledge to answer the next question:

If Bill ran 52 yards, how many feet did he ran?

We can do math to solve our answer. :

1 x 52 = 52.

Now we need to multiply 52 x 3.

That is a little bit to much, so lets make the problem easier!

By breaking up the problem \/ to make it more easier.

50 x 3. ( 5 x 3 = 15, just add a zero! ) = 150

3 x 2 = 6.

Next add:

150 + 6 = 156.

Thus the answer to your problem is, 156

Answer:

D(1,4) - the fourth vertex, the area is equal to 12

Step-by-step explanation:

A(2,-1), B(1,0),C(4,3), They are consecutive, we need to find the point D, find the midpoint of AC (O)

xo= (xA+xc)/2    x0= (-2+4)/2=1

y0=(yA+yC)/2    y0= (1+3)/2=2

0(1,2)

O is the midpoint of BD, so let's find the vertex D

X0= (xB+xD)/2     1= (1+xD)/2   xD=1

y0= (yB+yD)/2      2= (0+yD)/2    yD=4

D(1,4)

the vector DA is (-2-1, 1-4)= (-3,-3)

the vector DC is (4-1, 3-4)= (3,-1)

The modul of DC is sqrt ((-3)^2+(-3)^2)= 3*sqrt2(the length of the side Dc)

The modul of DA is sqrt (3^2+(-1)^2)= sqrt10(the length of the side DA)

cosD= (-3*3+(-3)(-1))/3*sqrt2*sqrt10=-6/3*2*sqrt5=-1/sqrt5

sinD= sqrt (1- 1/5)=2/ sqrt5

The lower limit of the 99% confidence interval for the true population proportion of binge drinkers cannot be determined without additional information.

To calculate the lower limit of the 99% confidence interval for the true population proportion of binge drinkers, we need to know the sample proportion and the sample size. While the information provided states that 2312 out of 5914 randomly selected full-time US college students were classified as binge drinkers, we don't have the specific sample proportion.

Additionally, the margin of error is required to calculate the confidence interval. Without these values or the methodology used to calculate the interval, we cannot determine the lower limit. It is important to note that the confidence interval is influenced by the sample size, sample proportion, and the desired level of confidence. Without more information, we cannot compute the lower limit of the confidence interval.
