The survey results are most at risk for undercoverage.

A survey is the process research method in which a group of things are tested to find insights into the data collected from the groups.

As its mentioned in the question that the employees must respond to the questionnaire within five days.

The survey results are not at risk for non-response bias as its mandatory for every employee to respond to the survey results.

There can be a chance that the survey does not cover all the points that should be include in order to get employee satisfaction.

Therefore the survey results are most at risk for undercoverage.

Answer:

You could pick as many as you like. Ideally you would use all the leaves on the tree, but that would be rather a large number to measure, and your parents might not be very happy if you stripped the tree bare!

So let's try 100 leaves.

How to get a random sample?

Here is one way you could get a random sample:

Try taking all the leaves on one branch of the tree. After you've discarded any that are broken, then see how many there are. If there are less than 100, then get the leaves from another branch until you have more than 100. Then write a different number (starting with 1) on each leaf with a marking pen.

Write the same numbers on small pieces of paper.

Fold the pieces of paper.

Put them into a hat and mix them up.

Draw 100 pieces of paper (without looking) from the hat. The first 100 pieces of paper you draw would give you the numbers of the leaves to use in the experiment.

The next thing you need to decide is how to measure the leaves, and

how accurate your measurements should be:

How to measure?

Keeping your leaves flat, use a ruler to measure the length of each leaf from the pointy part at one end of the leaf to the point where the leaf joins the stalk at the other end. Maybe your leaves bend a bit, but don't follow the main rib of the leaf as this would make measurement too difficult.

Just measure in a straight line as shown in the following diagram:

leaf

How accurate?

You should measure the length of each leaf to the nearest millimeter.

Now you're ready to begin.

Measure the length of each leaf to the nearest millimeter and record you results in a table, as follows:

Answer:

Year 2022

Step-by-step explanation:

Let number of years = x

Samantha :

Bonus + yearly earning

50 + 5x

Emily :

40 + 10x

Curent earning in 2018:

Years worked by Samantha = 6

50 + 5(6) = 50 + 30 = 80

Years worked by Emily = 2

40 + 10(2) = 60

Year when they'll both receive same amount :

80 + 5x = 60 + 10x

5x - 10x = 60 - 80

-5x = - 20

x = 20/5

x = 4 ; x = 4 years

2018 + 4 = 2022

Answer:

Step-by-step explanation:

the pot will be a cylinder,

V=3.14*r^2*h

V=3.14*(4.5)^2*7.5=476.89

The volume of the soup pot is equal to 476.89 cubic inches.

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube and for the cone it will be radius and height.

The space occupied by the cylinder in three-dimensional space is called the volume of the cylinder.

Given that the soup pot is 7.5 inches tall with a radius of 4.5 inches. The volume of the soup pot will be calculated as,

V=3.14 x r² x h

V=3.14 x (4.5)² x 7.5

V =476.89 cubic inches

Step-by-step explanation:

The probability for P(X<$400) is 0.7881.

The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean. In essence, standard deviation represents the degree of variability present in a given data collection.

Given:

Mean = $360

Standard Deviation = $50

We can use the z-score formula that is shown below:

Z = x - μ/σ

Where,

Z = standard score

x = observed value

μ = mean of the sample

σ = standard deviation

So,

z = 400 - $360/$50

z = 40/ 50

z= 0.8

and, P(x<400) = 0.78814

Answer:

822 × 5 + 2

Step-by-step explanation:

Given that:

4112 ÷ 5 = [tex]\frac{4112}{5}[/tex]

             = 822 remainder 2

To check if the answer is correct, we can write that;

[tex]\frac{4112}{5}[/tex] = 822 remainder 2

4112 = 5 x  822 remainder 2

       = 5 x  822 + 2

       = 822 x 5 + 2

4112 = 4112

Thus,the correct process of checking the answer is 822 x 5 + 2.

Step-by-step explanation:

Answer:

x = 2  +  √-16 [ (-2)⁻¹]

See steps below.

Step-by-step explanation:

Finding the zeroes of a function simply means solving for the unknown variable (in this case "x") when the function is equated to zero.

The function here is   [tex]f(x) = -(x + 1)^{2} - 4 = 0[/tex]

Start by opening the bracket. Ignore the minus sign. It will be reintroduced at the end of this step.

(x + 1)(x + 1)   = x² + x + x + 1    = x² + 2x + 1

Reintroduce the minus sign. Don't forget to put the result above back in a bracket.

- (x² + 2x + 1)  = -x² -2x -1

Place the expression back in the equation and solve. Make sure to put it back in the position where it was.

-x² - 2x - 1 - 4 = 0

Simplify the non-algebraic terms.

-x² - 2x - 5 = 0

Use Quadratic Formula to solve for x.

Quadratic formula: x =  -b ± √(b² - 4ac)

                                              2a

a = the coefficient of x² = -1

b = the coefficient of x  = -2

c = the unit term            = -5

So   x = -(-2)  ± √ [(-2)² - 4(-1 x -5)]

                       2(-1)

x = 2 + √-16                    or x = 2 - √-16

         -2                                          -2

This is where the evaluation ends, since the square root of minus sixteen cannot be evaluated. x hence is equal to a complex number. The above are the two values for x.

Next step is to put it in "a + bi" form.

x = 2  +  √-16  ÷  -2     =  2  +  √-16  x (-2)⁻¹

So   x = 2  +  √-16 [ (-2)⁻¹]

where

a is 2;

b is √-16

i is [(-2)⁻¹]

Answer:  4

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

Rule: The geometric mean of two numbers x and y is sqrt(x*y)

In this case, x = 2 and y = 8

So we have the geometric mean equal to sqrt(2*8) = sqrt(16) = 4

If you wanted to find the geometric mean of three values, then you'll multiply the numbers and take a cube root. If you had four values, then you multiply and apply a fourth root. And so on.
