A homeroom was interested in surveying their students to find out opinions about the schools media center. To facilitate data co

llection, the homeroom period was extended 30 minutes to allow everyone in the school ample time to respond to a short questionnaire.

Answer: nonresponse bias

Step-by-step explanation:

According to the information obtained, we can say that it is a non-response bias, since the sample obtained to extrapolate the result was not homogeneous, so these biases arise when the type of response to the non-response is affected in a social experiment. meet a standard among the population muesta¡ra.

Cognitive biases are found in ideas that make us partial. These thoughts, along with certain external circumstances, create what are known as response biases.

Two numbers whose sum is 44 and whose product is a maximum
Mashcka [7]

Answer:

x = y = 22

Step-by-step explanation:

It would help to know your math course. Do you know any calculus? I'll assume not.

Equations

x + y = 44

Max = xy

Solution

y = 44 - x

Max = x (44 - x)                    Remove the brackets

Max = 44x - x^2                   Use the distributive property to take out - 1 on the right.

Max = - (x^2 - 44x )               Complete the square inside the brackets.

Max = - (x^2 - 44x + (44/2)^2 ) + (44 / 2)^2 . You have to understand this step. What you have done  is taken 1/2 the x term and squared it. You are trying to complete the square. You must compensate by adding that amount on the end of the equation. You add because of that minus sign outside the brackets. The number inside will be minus when the brackets are removed.

Max = -(x - 22)^2 + 484

The maximum occurs when x = 22. That's because - (x - 22) becomes 0.

If it is not zero it will be minus and that will subtract from 484

x + y = 44

xy = 484

When you solve this, you find that x = y = 22 If you need more detail, let me know.

san4es73 [151]

Answer:

Step-by-step explanation

Volume of tank = l* b*h

= 18*16*13

=3744 cubic cm

Volume of cylinder = volume of tank

πr²h = 3744

3.14* (17/2)² * h = 3744

h= 3744 *2 *2/*17*17*3.14

h=16.5 cm
