Answer:

P(X<65)=0.9452

Step-by-step explanation:

This is a normal distribution problem.

-Given the mean age is 53 years and the standard deviation is 75, the probability of dying before age 65 is calculated as:

[tex]z=\frac{\bar x-\mu}{\sigma}\\\\\\=\frac{65-53}{7.5}\\\\=1.60[/tex]

#We check the value of z=1.60 on the z table:

[tex]P(X<65)=0.5+0.4452\\\\=0.9452[/tex]

Hence, the probability of dying before 65 is 0.9452

the probability that the person will die before the age of 65 is 0.9452.

[tex]P(X<65 ) = P[(X- \mu ) \div \sigma < (65 -53) \div 7.5][/tex]

= P(z <1.6 )

Now here we Using z table

So,

Answer:

Part A. [tex]\frac{84.3y}{12} = 7 +\frac{0.1\cdot y}{4}[/tex]

Part B. The correct quotient is (3 × 4)

Step-by-step explanation:

Part A.

To divide 84.36 by 12 we look for the Highest Common Factor of the whole number and the decimal portions of the numerator and the denominator individually as follows;

[tex]\frac{84.36}{12} = \frac{84+0.3636}{12} = \frac{2 \times 2 \times 3 \times 7+0.01\times 12\times 3}{12} = \frac{12 \times 7+0.03\times 12}{12}[/tex]

Therefore, dividing 84.36 by 12 gives [tex]\frac{12 \times 7+0.03\times 12}{12} = 7+0.03[/tex] = 7.03

When dividing 84.3·y by 12, therefore, we have;

[tex]\frac{12 \times 7+0.3\times y}{12} = 7 +\frac{0.1\cdot y}{4}[/tex]

Part B.

The correct quotient should have factors of the numerator

Therefore the divisor 12 should be represented as follows

[tex]\frac{12 \times 7+0.3\times y}{12} =\frac{12 \times 7+0.3\times y}{3 \times 4}[/tex]

The correct quotient therefore = (3 × 4)

Elena divided the decimal 84.36 by the whole number 12 to get the correct quotient of 7.03. The division process is similar to dividing whole numbers but includes placing the decimal point correctly in the quotient.

To answer the question, Elena divided a decimal by a whole number. Specifically, the division problem is 84.36 ÷ 12. Dividing a decimal by a whole number follows the same process as dividing two whole numbers, with the additional step of placing the decimal point in the quotient.

Set up the division problem with 84.36 inside the division bracket and 12 on the outside.

Start dividing from the left. 12 goes into 84 seven times (12 x 7 = 84), so put 7 above the 84 in the quotient.

Subtract 84 from 84, which leaves 0, and bring down the next digit, which is 3 (from the decimal part).

Since 12 does not go into 3, we place a 0 in the quotient above the 3 and bring down the next digit, which is 6.

Now we have 36. 12 goes into 36 three times (12 x 3 = 36), so place a 3 in the quotient above the 36.

Again, we subtract 36 from 36, leaving 0, with no more digits to bring down, so we have our answer.

The correct quotient is 7.03. Multiplying or dividing by powers of ten, as seen when working with decimals, involves shifting the decimal point. For example, when multiplying 45.86 by 100, you would move the decimal point two places to the right, giving 4586. Conversely, dividing 1.9436 by powers of 10 shifts the decimal point to the left. The significance of this process is underlined by the fact that in scientific fields, calculations often require adjusting the decimal by powers of ten to maintain precision and correct significant figures.

It should be noted that a calculator provides the raw numerical result of a division and doesn't account for the significant figures involved; therefore, it's essential to consider how many decimal places are appropriate for the situation.

Units for the area are in square inches.

==============================================================

Work Shown:

The radius of each circle is 2 inches. Double this value to get the diameter to be 4 inches.

Two circles along the top have their diameters combine to 8 inches total, which is the side length of the square.

The area of the entire square, before we subtract off the circles, is 8^2 = 64 square inches.

Let A = 64

The area of one circle is pi*r^2 = pi*2^2 = 4pi square inches. Four circles combine to an area of 4*4pi = 16pi square inches.

Let B = 16pi

Subtract A and B to get the area of the shaded region, which is the leftover area after subtracting off the four circles

A-B = 64-16pi

Answer:

3 miles

Step-by-step explanation:

The circumference of a circle can be found using:

c=[tex]\pi d[/tex]

We know the circumference is [tex]3\pi[/tex], so we can substitute that in for c

[tex]3\pi[/tex]=[tex]\pi d[/tex]

We want to find the diameter. To do this, we need to get d by itself. It is being multiplied by pi. To undo this, divide both sides by pi. This will cancel pi, and leave d by itself.

[tex]3\pi /\pi =\pi d/ \pi[/tex]

3=d

So, the diameter is 3 miles

Answer:

Diameter is 3

Step-by-step explanation:

C=2πr

3π = 2πr

3π / 2π = r  (Divide each side by 2π)

3/2 = r   (Simplify π)

3/2 *2 = d  (d = 2r)

d = 6/2 = 3

Answer:

Yes, it is possible

Step-by-step explanation:

In a triangle, the length of the longest side of the triangle cannot be larger than the sum of the lenghts of the two shortest sides.

In formula, this means that:

[tex]c\leq a+b[/tex]

where

c is the length of the longest side

a, b are the lengths of the shortest side

In this problem, we want to build a triangle using 3 pieces of lumber, each of length:

a = 3 ft

b = 7 ft

c = 8 ft

We can verify that the length of the longest piece of lumber is less than the sum of the lengths of the other two sides, so:

[tex]8\leq 3+7 = 10[/tex]

Therefore, yes, it is possible to build a closed triangular pen.

The question is about the Triangle Inequality Theorem in Geometry. It asks if a triangle can be formed with given lengths of 3 ft, 7 ft, and 8 ft. By verifying with the theorem, we can confirm that a triangle can be formed.

The subject of the question is determining if a triangle can be formed with three given lengths. This topic belongs to Geometry, a branch of Mathematics. To form a triangle, the lengths must satisfy the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side. In this case, we can plug our given lengths into this theorem:

All these inequalities hold true, so yes, Mrs. Barto can build a closed triangular pen for her pet rabbit with the three pieces of lumber.

Wheres the diagram?

Step-by-step explanation:

A Venn Diagram is commonly used in probability theory to visualize and calculate probabilities. The probability of two conditions being met can be found by taking a sum of the probabilities of both conditions and their intersection, and subtracting the probabilities of each condition occurring separately. A Tree Diagram is another tool used to easily represent and calculate probabilities of multiple outcomes.

The use of a Venn Diagram is a common strategy in probability theory to help visualize and calculate probabilities effectively. To begin solving these problems, label each piece of the Venn Diagram clearly and note the probability or frequency of each part. Start by labeling the overlapping section first.

In the case of calculating the probability that a student belongs to a club and works part-time, identify the overlapping section of the Venn Diagram that represents both these conditions. The probability of this will be the sum of the probabilities of the student belonging to a club, working part-time, and both these conditions minus the probabilities of each of these conditions occurring separately.

Another tool that can be useful for visualizing and calculating probabilities is a Tree Diagram. A tree diagram uses branches to represent the possible outcomes of a scenario, which makes it easier to visually work through and solve probability problems. For instance, to visualize the probability of a man developing cancer in his lifetime and having at least one false-positive test, a tree diagram could be used where one branch represents the man developing cancer and the other branch represents the man having a false-positive.

Answer:

Volume: [tex]\frac{2}{3}\pi r^3[/tex]

Ratio: [tex]\frac{2}{9}r[/tex]

Step-by-step explanation:

First of all, we need to find the volume of the hemispherical tank.

The volume of a sphere is given by:

[tex]V=\frac{4}{3}\pi r^3[/tex]

where

r is the radius of the sphere

V is the volume

Here, we have a hemispherical tank: a hemisphere is exactly a sphere cut in a half, so its volume is half that of the sphere:

[tex]V'=\frac{V}{2}=\frac{\frac{4}{3}\pi r^3}{2}=\frac{2}{3}\pi r^3[/tex]

Now we want to find the ratio between the volume of the hemisphere and its surface area.

The surface area of a sphere is

[tex]A=4 \pi r^2[/tex]

For a hemisphere, the area of the curved part of the surface is therefore half of this value, so [tex]2\pi r^2[/tex]. Moreover, we have to add the surface of the base, which is [tex]\pi r^2[/tex]. So the total surface area of the hemispherical tank is

[tex]A'=2\pi r^2 + \pi r^2 = 3 \pi r^2[/tex]

Therefore, the ratio betwen the volume and the surface area of the hemisphere is

[tex]\frac{V'}{A'}=\frac{\frac{2}{3}\pi r^3}{3\pi r^2}=\frac{2}{9}r[/tex]
