for the given scenario the distribution is applicable, (a) negative binomial (b) binomial (c) normal (d) exponential (e) Poisson (f) uniform, (g) geometric.

The waiting process is frequently a part of geometric, negative binomial, and exponential random variables; in these cases, the waiting process is continuous until something occurs, rather than a count of trials. (Exponential). Large numbers of independent quantities that are averaged and summed typically have distributions that are close to normal. For observed counts, there are two models: Poisson and binomial. For binomial, there is a predetermined number of trials, leading to a clearly defined maximum count; for Poisson, there is no clearly defined maximum potential count. When there is no evident preference for one interval of distance or time over another such equal-length interval, the distribution is continuous.

We have to identify the best described as binomial, geometric, negative binomial, Poisson, uniform distribution and so on.

The 34% would be considered a statistic.

A statistic is a numerical measurement of a characteristic of a population.

It is calculated by taking the number of individuals in the sample with a certain characteristic, such as preferring charcoal to gas grills, and dividing it by the total number of individuals in the sample.

For example, in the survey of 1000 adults, if 340 of them prefer charcoal to gas grills, then the statistic would be calculated as 340/1000 = 0.34 = 34%. This statistic can then be used to make inferences about the entire population. In this case, it can be inferred that 34% of the population prefers charcoal grills to gas grills.

Answer: 18000 cm^2

Step-by-step explanation:

1.5 meters = 150 cm

        = 18000 cm^2

The best combination of belts and coats for this economy to produce is 95 belts and 1 coat. If the annual demand, setup cost, and cost per unit changes, then the EOQ formula can be used to determine the best combination of belts and coats to produce.

The best combination of belts and coats for this economy to produce can be determined using the economic order quantity (EOQ) formula. The EOQ formula helps businesses determine the most cost-effective order quantity when ordering goods. The EOQ formula is expressed as:

EOQ = √2AS/C

Where A is the annual demand for the product, S is the setup cost, and C is the cost per unit.

Using the EOQ formula, the best combination of belts and coats for this economy to produce is determined by calculating the EOQ for each product. For example, if the annual demand for belts is 95, the setup cost for belts is $1 and the cost per unit for belts is $2, then the EOQ for belts is:

EOQ = √2(95)(1)/(2)

EOQ = 95 belts

Similarly, if the annual demand for coats is 1, the setup cost for coats is $2, and the cost per unit for coats is $3, then the EOQ for coats is:

EOQ = √2(1)(2)/(3)

EOQ = 1 coat

Therefore, the best combination of belts and coats for this economy to produce is 95 belts and 1 coat. If the annual demand, setup cost, and cost per unit changes, then the EOQ formula can be used to determine the best combination of belts and coats to produce.

The value of (hg)(x) would be  4x.

What is the function?

A function is a mathematical relationship between a set of inputs (also known as domain) and a set of possible outputs (also known as range). The inputs are usually represented by variables, such as 'x' in the examples you provided. The outputs are usually represented by expressions, such as 'x² - 8x + 4' in the example f(x) = x² - 8x + 4.

(hg)(x) is the composition of two functions h(x) and g(x). In this case, it would be equivalent to h(g(x)), which means to first apply the function g(x) to the input x, then apply the function h(x) to the output of g(x).

(hg)(x) = h(g(x)) = h(4x - 3) = (4x - 3) + 2 = 4x.

The Sun's rays hit the Earth most directly close to the equator, whereas near the poles they hit at a sharp angle.

This indicates that the tropics are warmer than the poles and that higher latitudes absorb less solar radiation per square centimeter (or inch) of surface area than lower latitudes do.

The incoming solar energy is more direct (almost perpendicular or closer to a 90° angle) when the sun's rays hit the surface of the Earth close to the equator. Warmer temperatures result from the solar radiation being concentrated over a smaller surface area.

Near the equator, the incoming solar radiation impacts the Earth's surface more directly (nearly perpendicular or closer to a 90° angle). Because the sun radiation is concentrated over a smaller surface area, it leads to warmer temperatures.

Since less surface area receives sunlight at the equator than at the poles, it warms up more quickly. Less atmosphere needs to be traveled through at the equator than at the poles.

As a result, the Earth's surface receives more solar heat. The variance in solar energy received at various latitudes affects atmospheric circulation.

The mean of the population can be calculated by finding the sum of all the heights and dividing it by the total number of observations.

This is also known as the arithmetic mean and can be represented by the formula:

Mean = (Sum of Observations) / (Number of Observations)

In this case, the sum of all the heights is 10,800 and the total number of observations is 100. Therefore, the mean of the population is:

Mean = 10,800 / 100 = 108 inches

To verify this result, we can also look at the histogram. Since the heights are grouped into intervals of 10 inches, the mean should be around the midpoint of the tallest bar, which is 108 inches. This confirms our calculation of the mean.

Answer:

Step-by-step explanation:

Since this equation uses order of operations, you should solve what's in the parenthesis first.  

48 ÷ 2 = 24

Now you have 24 - 4²2 + 2 × 2.  The next thing to solve in order of operations is exponents, so square 4.  

4² = 16

Now you should have 24 - 16 (2) +2 × 2.  Next is multiplication, so multiply 16(2) and 2 × 2.  

16 × 2 = 32, and 2 × 2 = 4

Now you have 24 - 32 + 4.  This should look a lot more simple now.  Simply do the math from here; doesn't matter how.  

24 - 32 = -8

A technique for determining a function's derivative is differentiation. Mathematicians use a procedure called differentiation to determine a function's instantaneous rate of change based on one of its variables. The most typical illustration is velocity, which is the rate at which a distance changes in relation to time.

Differentiation is the ratio of a slight change in one quantity to a little change in another that depends on the first quantity.

Differentiation is the process of determining the maximum or lowest value of a function, the speed and acceleration of moving objects, and the tangent of a curve.
