Answer:

No

It could be purely due to chance.

Step-by-step explanation:

A population is defined as the whole group which has the same characteristics. For example a population of the college belongs to the same college . But a sample may be an element of a population.

So it is not necessary for a population to have the same characteristics as the sample.

But it is essential for the sample to have at least one same characteristics as the population.

So we would not be correct in inferring that such a relationship also exists in the population.

It is a hypothesis which can be true or false due to certain conditions or limitations as the case maybe.

For example in a population of smokers some may be in the habit of taking cocaine. But a sample of cocaine users does not mean the whole population uses it.

It could be purely due to chance if we find out that there is a relationship between parents’ and children’s party identification in the population.

The classification of each cost item as a differential cost, a sunk cost, an opportunity cost, or None, is as follows:

1. Cost of the old X-ray machine                                  Sunk cost

2. The salary of the head of the Radiology Dept.      None

3. The salary of the head of the Laboratory Dept.     None

4. Cost of the new color laser printer                          Differential cost

5. Rent on the space occupied by Radiology             None

6. The cost of maintaining the old machine               Differential cost

7. Benefits from a new DNA analyzer                         Opportunity cost

8. Cost of electricity to run the X-ray machines         Differential cost

9. Cost of X-ray film used in the old machine            Sunk cost

A differential cost is a cost that arises as the cost difference between two alternatives.

A sunk cost is an irrelevant cost in managerial decisions because it has been incurred already and future decisions cannot overturn it.

An opportunity cost is a benefit that is lost when an alternative is not chosen.

Thus, the above cost classifications depend on the decision to replace the old X-ray machine with a new machine (new X-ray or new DNA analyzer).

Answer:

p=39/45=13/15

Step-by-step explanation:

The angle 7 is the alternative interior angle to angle 2.

Given that,In the diagram a || bWe need to find the alternate interior angle to <2 .Alternate interior angles are the angles that are formed when a transversal crosses two parallel lines.

They are the angles that are on opposite sides of the transversal and inside the two parallel lines.

Thus, in the given diagram, the angle that is opposite to angle <2 and is inside the two parallel lines a and b is the alternate interior angle to angle <2.

We can see that the alternate interior angle to angle <2 is <7. Therefore, the alternate interior angle to angle <2 is <7.

X=32, Y=148

Step-by-step explanation:

X is 32 degrees because it is parallel to that 32 between f and b.

Y is 148 degrees because x and y together make a straight line and a straight line is 180 degrees therefore, 180-32 = 148.

The minimum number of times Johnny needs to use the wheelbarrow until the delivery truck is 70% filled, obtained from the volume of the wheelbarrow and the volume of the truck is about 41 times.

The volume of a solid is the three dimensional space the solid occupies.

The specified dimensions of the wheelbarrow and truck indicates that the volumes of the wheelbarrow and the truck are;

Volume of the wheelbarrow = 2 ft × 1.5 ft × 3 ft = 9 ft³

Volume of the truck = 11 ft × 8 ft × 6 ft = 528 ft³

70% of the volume of the truck = 70% × 528 ft³ = 369.6 ft³

The number of times Johnny uses the wheelbarrow = 369.6 ft³ ÷ 9 ft³ ≈ 41.0

The number of times Johnny needs to use the wheelbarrow is about 41 times

Step-by-step explanation:

Mikey Johnson shipped out 34 2/7 pounds of electrical supplies. The supplies are placed in individual packets that weigh 2 1/7 pounds each. Therefore, Mikey shipped out 16 packets of electrical supplies.

To solve the problem, we can use the following steps.Step 1: Find the weight of each packet.

We are given that the weight of each packet is 2 1/7 pounds.

To convert this mixed number into an improper fraction, we can multiply the whole number by the denominator and add the numerator.

This gives us: 2 1/7 = (2 × 7 + 1) / 7= 15 / 7 pounds.

Therefore, the weight of each packet is 15/7 pounds.

Now, divide the total weight by the weight of each packet.

We are given that the total weight of the supplies shipped out is 34 2/7 pounds.

To convert this mixed number into an improper fraction, we can multiply the whole number by the denominator and add the numerator.

This gives us: 34 2/7 = (34 × 7 + 2) / 7= 240 / 7 pounds.

Therefore, the total weight of the supplies is 240/7 pounds.

To find the number of packets that Mikey shipped out, we can divide the total weight by the weight of each packet.

This gives us: 240/7 ÷ 15/7 = 240/7 × 7/15= 16.

Therefore, Mikey shipped out 16 packets of electrical supplies.

Answer:

\(C = 25.1 \text{ cm}\)

Step-by-step explanation:

We can find the circumference of the circle by plugging the given radius value 8 cm into the formula:

\(C = \pi d\)

Note: This formula can also be written as \(C = 2\pi r\) because \(2r = d\).

↓ plugging in the given radius

\(C = 8\pi \text{ cm}\)

↓ rounding to the nearest tenth

\(\boxed{C = 25.1 \text{ cm}}\)

The distance between points AB at A(2, 5) and B(2, 10) is 5 units

An equation is an expression that shows the relationship between two or more numbers and variables.

The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is:

\(AB=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\)

Let us assume that AB has coordinate at A(2, 5) and B(2, 10), hence:

\(AB=\sqrt{(10-5)^2+(2-2)^2}=5\ units\)

Answer:

The correct option is  C

Step-by-step explanation:

From the question we are told that

     The number of independent variables is  \(n = 3\)

     The number of observation is  \(z = 47\)

Since n is are independent variables then their degree of freedom is  3

   The  denominator(i.e z) degrees of freedom is evaluated as

            \(Df(z) = z - (n +1)\)

          \(Df(z) = 47 - (3 +1)\)

          \(Df(z) = 43\)

So for the numerator (n) the degree of freedom is  Df(n) = 3

So for the denominator(i.e z) the degree of freedom is  Df(z) = 43

A. It looks like Harry made a mistake when adding the two numbers written in scientific notation. In scientific notation, numbers are written in the form a x 10^b, where a is a number between 1 and 10 and b is an integer exponent. When adding or subtracting numbers written in scientific notation, it's important to make sure that the exponents are the same before performing the operation. In this case, Harry appears to have added the two numbers together without aligning the exponents, resulting in an incorrect answer.

B. Here is the correct solution to the problem:

(4.25 x10^13) + (2.10 x 10^14) =

4.25 x 10^13 + 2.10 x 10^14

= 4.25 x 10^13 + 21 x 10^13

= (4.25 + 21) x 10^13

= 25.25 x 10^13

= 2.525 x 10^14

The correct answer is 2.525 x 10^14.

The circumference of a circle of radius r is given by the equation presented as follows:

C = 2πr.

The parameters for this problem are given as follows:

d = 9 -> r = 4.5.

(as the radius is half the diameter)

Hence the circumference is given as follows:

C = 2 x π x 4.5

C = 28.27 ft.

The cost is of $4.22 per ft, hence the total cost is given as follows:

Answer:

.583

Step-by-step explanation:

7÷12 London division

Hello there.

You are asking to change 7/12 into a recurring decimal. To do this, you simply have to divide 7 by 12. (7 ÷ 12.)

After dividing 7 by 12, we get the answer of 0.58333333. Since a recurring decimal is a decimal that continues on and on, occurring again and again, I repeated the 3 value to show this. Additionally, although I can't properly format it on Brainly, you can also draw a line above the 3. A line such as that one means that the value it is over repeats infinitely, or forever. In other words, 0.583 with a line over the 3 is the same value as 0.583333, with 3 continuing forever.

Therefore, 7/12 as a recurring decimal is 0.58333333 - with a 3 that continues on forever.

Answer:

115 hours.

Step-by-step explanation:
