The sample for a study exhibits question wording bias. Select the statement that best describes the bias in the study
-Each subject in the study completes one of three different surveys. Each survey asks the same questions but using slightly different wording
-One or more questions on the survey is vague, confusing, leading, or lacks information
-The questions on the survey are short answer rather than yes or no questions
-The survey is more than 20 questions long

Answer:

ans b is the correct answer because

first we should have to multiply 1.4×10 power 6 which means 14000000 km

then we should divide with mars diameter which is 7000 km

14000000/7000km= 2× 10 power 3

2× 10 power 3

2×1000

therefore 2000 km is the ans

Step-by-step explanation:

A quadrilateral is a shape that has 4 sides, along with other rules.

A rhombus (also known as a diamond) has 4 sides.

A parallelogram has 4 sides.

A trapezoid has 4 sides.

A circle does not have 4 sides, since its one side continues infinitely.

Answer:

5.4

Step-by-step explanation:

Circumference = 2 x 3.14 x radius

To find this information, you must first divide:

33.912 ÷ 2 = 16.956

Then, divide:

16.956 ÷ 3.14 = 5.4

So then your answer is:

Radius = 5.4

Answer: Point P is at (3, 7)

Step-by-step explanation: the distance from point a to point B is 10.8. 10.8 divided by 3 is 3.6, so you have to find a point that 3.6 from point a. Using a graph, I found the answer to be (3,7)

Answer:

A) (-2,-1)

Step-by-step explanation:

It would be in Quadrant III, so (-2,-1)

Given:

Height of a man = [tex]61\dfrac{5}{12}[/tex] inches

Height of the daughter = [tex]58\dfrac{4}{9}[/tex] inches

To find:

How much taller is the man?

Solution:

It this problem, we need to find the difference between the heights of the man and his daughter.

Difference between the heights [tex]=61\dfrac{5}{12}-58\dfrac{4}{9}[/tex]

                                                      [tex]=\dfrac{732+5}{12}-\dfrac{522+4}{9}[/tex]

                                                      [tex]=\dfrac{737}{12}-\dfrac{526}{9}[/tex]

Taking LCM, we get

Difference between the heights [tex]=\dfrac{3(737)-4(526)}{36}[/tex]

                                                      [tex]=\dfrac{2211-2104}{36}[/tex]

                                                      [tex]=\dfrac{107 }{36}[/tex]

                                                      [tex]=2\dfrac{35 }{36}[/tex]

Therefore, the man is [tex]2\dfrac{35}{36}[/tex] inches taller than his daughter.

Answer:

5.25

Step-by-step explanation:

So lets gather our information(Note that I use x as the small x value and X as the larger and missing value)

First off, we know that x is 3.

We know that the X value is a scale of x by 1.75.

We can think of this as 1.75x.

So to find X, we can multiply x by the scale 1.75:

x*1.75=X

plug in the value we know for x:

3*1.75=X

=

5.25=X

So our answer is 5.25!

Hope this helps! :)

Answer:

B

Step-by-step explanation:

since x is GREATER than -25, the shaded part has to be on the right of -25

Answer: B

Step-by-step explanation:

The answer is (C) 2x+1/ 2x+5.

This is just finding like terms.

Like terms are terms that are the same, like 2x and 3x for example, would be like terms. (This is not in the problem by the way.) Just divide the like terms, and that's your answer.

I tried to give a good explanation but I'm super tired. Just trying to help.

The expression is equivalent to the quotient is (2x+1)/(2x+5). Therefore, option C is the correct answer.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Given that, (4x²-8x-5)/(4x²-25)

= (4x²-10x+2x-5)/((2x)²-(5)²)

= [2x(2x-5)+1(2x-5)]/(2x-5)(2x+5)

= [(2x-5)(2x+1)]/(2x-5)(2x+5)

= (2x+1)/(2x+5)

Therefore, option C is the correct answer.

Answer:

8 cm

Step-by-step explanation:

The area of the shaded portion is:

[tex]a = \pi \times (( {r1)}^{2} - {(r2}^{2})) [/tex]

A=39π cm^2

r1 is the radius of the large circle

r2=5 cm

Answer:

42.2 cubic inch

Step-by-step explanation:

Applying,

V = πr²h/3.................... Equation 1

Where, r = radius of the circular base, h = height of the cone, π = pie.

But,

r = P/2π..................... Equation 2

Where P = circumference of the circular base.

Substitute equation 2 into equation 1

V = π(P/2π)²(h)/3

V = P²h/12π.................. Equation 3

From the question,

Given: h = 18.4 in, P = 9.3 in

Constant: π = 3.14

Substitute these values into equation 3

V = (9.3²)(18.4)/(12×3.14)

V = 42.2 cubic inch
