Which fraction is equal to 0.20%? 1/20 1/40 1/50 1/400 1/500

The probability that a Poisson random variable X equals 2, given that its variance is 3, is approximately 0.2240.

The student asks about finding the probability that a Poisson random variable X takes on a value exactly equal to 2, given that the variance of X is 3. We know for a Poisson distribution, the variance is equal to its mean, which is denoted by λ (lambda). Therefore, λ = 3.

Using the formula for the Poisson probability mass function (PMF), P(X = k) = (e^(-λ) * λ^k) / k!, we can calculate P(X = 2). Substituting λ = 3 and k = 2, we have:

P(X = 2) = (e^(-3) * 3^2) / 2! = (0.0497871 * 9) / 2 = 0.224041.

We can round this probability to four decimal places:

P(X = 2) ≈ 0.2240.

The question involves setting up an equation to determine Clem Kadiddlehopper's current age based on his age in six years and 26 years ago. By solving the equation x + 6 = 5(x - 26), we find that Clem is currently 34 years old.

Explanation:

The question asks us to determine Clem Kadiddlehopper's current age based on information about his age in future and past years. Let's define Clem's current age as x years old.

In six years, he will be x + 6 years old. It is stated that in six years, Clem will be five times as old as he was 26 years ago. Since 26 years ago he was x - 26 years old, we can write the equation: x + 6 = 5(x - 26).

To find Clem's age, we will solve the equation:

Therefore, Clem Kadiddlehopper is currently 34 years old.

commission would be 9000 * 0.10 = 900

 he would make $900

The function to find the number of rides Jay went on is [tex]\( 10.50 + 4.50x = 46.50 \)[/tex]

Let x be the number of rides Jay went on.

The cost of the entrance fee is $10.50, and the cost per ride is $4.50. The total amount Jay spent is $46.50. The equation representing this scenario is:

[tex]\[10.50 + 4.50x = 46.50\][/tex]

To find the number of rides, you can solve for x:

1. Subtract the entrance fee from the total amount:

  [tex]\[ 46.50 - 10.50 = 36.00 \][/tex]

2. Divide by the cost per ride:

 [tex]\[ \frac{36.00}{4.50} = 8 \][/tex]

So, Jay went on 8 rides.

The function to find the number of rides x is:

[tex]\[f(x) = 10.50 + 4.50x\][/tex]

Setting this equal to the total expenditure ($46.50), the function to find x is:

[tex]\[10.50 + 4.50x = 46.50\][/tex]

If the CPI increased by 8.3%, therefore this means that there was a fractional increase of 0.083. So amount increased is:

CPI increase = 141 * 0.083 = 11.703

Therefore the end of year CPI is the sum of the original and the increase:

end of year CPI = 141 + 11.703 = 152.703

Answer:

152.703

The value of the 50 divided by 2.5 divided by 0.04 is equal to  500.

To calculate 50 divided by 2.5 divided by 0.04, should follow the order of operations,

which is parentheses, exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).

However, there are no parentheses or exponents in this expression, so we can proceed directly to multiplication and division:

50 ÷ 2.5 ÷ 0.04

First, divide 50 by 2.5:

50 ÷ 2.5 = 20

Next, divide the result (20) by 0.04:

20 ÷ 0.04 = 500

Therefore, 50 divided by 2.5 divided by 0.04 equals 500.

Final answer:

To find out the total hardener needed for 15 containers of resin, multiply 15 by the amount per container, 50ML, which equals 750ML of hardener in total.

Explanation:

To calculate the total amount of hardener needed for 15 containers of resin, we use a simple multiplication. We have been given that each container requires 50ML of hardener. Therefore, we multiply the number of containers by the amount of hardener needed per container.

Calculation:
Number of containers × Amount of hardener per container = Total amount of hardener
15 containers × 50ML/container = 750ML

Thus, for 15 containers of resin, you would need to add a total of 750ML of hardener.

Answer:58 metric ton

Step-by-step explanation:

Given

Fifty eight thousand kilogram of solid waste

We need to convert it into metric tons

and we know 1 metric ton is equivalent to one thousand kilogram i.e. 1000 kg

so 58,000 kg is equivalent to 58 metric ton

The measure of angles 1 and 2 are 16.5 and 73.5 respectively.

The sum of the two acute angles is complementary.

Let the complementary acute angles be x and y

Since they form a right angle triangle, hence;

x  + y = 90 ............................. 1

If the measure of one acute angle is 3 times the sum of the other acute angle and 8, this is expressed as x = 3(y + 8)

Substitute the value of x into the equation 1 as shown:

3(y+8) + y = 90

3y + 24 + y = 90

4y + 24 = 90

4y = 90 - 24

4y = 66

y = 66/4

y = 16.5

Get the other acute angle:

x = 90 - y

x = 90 - 16.5

x = 73.5 degrees

Hence the measure of angles 1 and 2 are 16.5 and 73.5 respectively.

Final answer:

The region e refers to the inside of a cylinder defined by x² + y² = 16 and between the planes z = -4 and z = 1. It represents a three-dimensional space bounded both radially, by the cylinder, and vertically, by the planes.

Explanation:

The region described in the question is a cylindrical volume in three-dimensional space. To visualize this region, we remember that the cylinder is defined by the equation x2 + y2 = 16, which is the set of points in the xy-plane that are at a distance of 4 from the origin (since the radius is √16 = 4). This cylinder extends indefinitely in the positive and negative z-directions.

The planes z = -4 and z = 1 act as boundaries in the z-direction, trimming the cylinder down so that we're only considering the portion of the cylinder between these two planes. Thus the region e of interest is the set of points inside the cylinder that lie at a height between z = -4 and z = 1.

This type of region is common in problems involving volume calculations, especially when using integral calculus to determine the volume of the shape or when analyzing physical phenomena like fluid flow or electric fields within prescribed bounds.

Ten as 9 hundreds is 9 thousands.

Place value is the value of each digit in a number.

For example 5 in 350 is 5 tens or 50.

The given digit is 9 thousand which can be written as 9,000

It can be written as,
