what is 37 + 8 + (78+7) x 56 / 8

Answer:cottontail

The answer is:You​ shouldn't expect to get exactly 5000​ heads, because you cannot predict precisely how many heads will occur.

However, according to the law of large numbers, the frequencies of events with the same likelihood of occurrence even out, given enough trials or instances.

For example, in the case of  a fair coin, where both head and tail have equal probability of occurrence, as the number of tosses becomes sufficiently large (say 1 million tosses), the ratio heads to tails in the outcome will be extremely close to 1:1.

So according to the law, we should expect to approach a point where half of the outcomes are heads and the other half are tails, as the number of tosses become very large.

5. JL (with the line segment symbol above)

Answer:

a = - 1/2b + 1/6w + 2/3

Step-by-step explanation:

w= 3(2a+b) - 4

Add 4 on both sides.

w + 4 = 3(2a+b)

Divide 3 into both sides.

w/3 + 4/3 = 2a+b

Subtract b on both sides.

w/3 + 4/3 - b = 2a

Divide 2 into both parts.

w/3/2 + 4/3/2 - b/2 = a

a = w/6 + 4/6 - b/2

a = 1/6w + 2/3 - 1/2b

Answer:

a=(w-3b+4)/6

Step-by-step explanation:

w= 3(2a+b) -4

w=6a+3b-4

6a= w-3b+4

a=(w-3b+4)/6

Managers, goods, services, and technology are all needed in developing countries, and therefore, they provide new markets for companies that can supply these essentials.

Developing countries often have growing economies and increasing consumer demands. As these countries strive for development and improvement, they require effective management to drive their businesses and organizations. Managers play a crucial role in overseeing operations, implementing strategies, and maximizing efficiency.

Additionally, developing countries require goods and services to meet the needs of their populations. This includes basic necessities such as food, clothing, and shelter, as well as other essential products and services like healthcare, education, infrastructure development, and transportation. Companies that can provide these goods and services have an opportunity to enter new markets and cater to the demands of the growing population.

Answer:

Step-by-step explanation:

The y-intercept is 3.

The rate of change is 2 and the initial value 5.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A zoo charges a rental fee plus $2 per hour for strollers.

The total cost of 5 is $13.

Assume the relationship is linear.

Let x be the number of hours.

And y be the total cost.

So,

y = 2x + m, where m is the rental fee.

Here, x = 5 and y = 13

So,

13 = 10 + m, where m is the rental fee.

m = 3

So, the equation is y = 2x + 3.

When x = 1,

y = 5.

Here, 3 is the y-intercept and 2 is the rate of change.

Hence, 3 is the y-intercept and 2 is the rate of change.

The variance of z is - 177.1788.

The discrete random variable X representing the number of errors per 100 lines of software code has the following probability distribution. X 2 3 4 5 6 P(X) 0.01 0.25 0.4 0.3 0.04

We can apply Theorem 4.2 to find the variance of X. Theorem 4.2: Let X be a discrete random variable with probability distribution p(x). If the mean of X is μ and the variance of X is σ², then μ = E(X) = ∑x p(x) and σ² = Var(X) = E(X²) - [E(X)]².

Now, we find the mean and variance of the discrete random variable z = 3X – 2.

The mean of z = 3X - 2 is E(z) = E(3X - 2) = 3E(X) - 2.

Hence, the mean is μz = 3(2)(0.01) + 3(3)(0.25) + 3(4)(0.4) + 3(5)(0.3) + 3(6)(0.04) - 2= 14.53.

The variance of z = 3X - 2 is Var(z) = Var(3X) = 9Var(X).

Hence, the variance of X is σz² = 9Var(X) = 9[E(X²) - [E(X)]²] = 9[(2²)(0.01) + (3²)(0.25) + (4²)(0.4) + (5²)(0.3) + (6²)(0.04) - 14.53²] = 34.0021 - 211.1809 = - 177.1788

Answer:

45 squared units

Step-by-step explanation:

So we know that the width of the rectangle is 3 units, and that the length of the rectangle is 5 times greater than the width. With simply maths we can find that the length we use the equation 3 multipled 5 = 15.

So we now know the length of the triangle is 15 units, so to find the area of a rectangle the equation would be: Length times width

3 units multiped by 15 units = x

x = 45 squared units

As per the concept of triangle, Adjacent angles are the one which has two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

In math, Angles are formed when two lines intersect.

Here they are measured as a rotation from one side to the other.

And for the convention, the measurement of angles in a plane is considered positive when the rotation is counter-clockwise and is negative when the rotation is clockwise.

Here we need to find the  two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

While we looking into the given question, we know that two angles sharing a common vertex and a side but no common interior points are called adjacent angles.

Therefore, Adjacent angles can be formed when dividing a bigger angle into several smaller parts, thus introducing common rays between the angles.

18 ft is equal to 6 yards. A yard is one linear yards. "Yd" is the yard symbol. It is equivalent to three feet or 36 inches.

The majority of cloth is now sold by the linear yard. A linear yard is 36" long, with a width that varies depending on the cloth roll. Only the length of the material is considered when measuring in linear yards. To calculate square yards, multiply the length and width in yards. In a yard, there are 36 inches. The length of a yard of fabric is 36 inches. Calculating the amount of fabric required for a sewing job is a little more difficult than that, though. A yard of fabric is always one yard long, however the breadth varies depending on where you get it. Between 33 and 44 inches are the typical widths.

Add the conversion factor "0.33333333333278" to the number in feet.

The amount of sugar in the entire shipment is 97(1)/(2) tons.

We are given that a shipment of sugar fills 2(1)/(5) containers. If each container holds 3(3)/(4) tons of sugar, we need to find the amount of sugar in the entire shipment.

Step-by-step explanation:

One container of sugar holds 3(3)/(4) tons of sugar. There are 2(1)/(5) containers of sugar in the shipment.

Amount of sugar in one container = 3(3)/(4) tons

Amount of sugar in 2(1)/(5) containers

= 2(1)/(5) × 3(3)/(4) tons

= 13/5 × 15/4 = 195/20

= 97(1)/(2) tons

The average of a distribution, also known as the mean, is calculated by dividing the sum of all the observations by the total number of observations.

To understand why this calculation yields the average, consider the following:

Summation of x: The sum of all the observations, denoted as Σx (capital sigma x), represents the total value obtained by adding up all the individual values in the distribution. For example, if we have a set of observations {2, 4, 6, 8}, the summation of x would be 2 + 4 + 6 + 8 = 20.

Number of observations: The total number of observations, denoted as N, represents the count of how many values are included in the distribution. Using the previous example, if we have the set of observations {2, 4, 6, 8}, the number of observations N would be 4.

Division: By dividing the sum of all the observations (Σx) by the total number of observations (N), we calculate the average. In mathematical notation, the average (mean) is expressed as:

Mean (average) = Σx / N

Using our previous example, the average (mean) would be: 20 / 4 = 5.

The division operation by the total number of observations normalizes the sum of the values, resulting in an average value that represents the central tendency of the distribution. It gives us a measure of the "typical" or "average" value within the set of observations.
