RESEARCH STUDY 11.2: Dr. Bloedorn is a health psychologist who researches nutrition. She is curious as to whether a new drink additive will help people consume fewer calories during a meal. The drink additive is a white, odorless, tasteless powder that a person can add to any drink. She collects a random sample of 63 overweight students on campus and measures the calories they eat during lunch using a bomb calorimeter. She then gives this additive to the same 63 participants to use at dinner and measures how many calories they eat (again using the bomb calorimeter). Imagine that Dr. Bloedorn finds no difference between the calories consumed with the drink additive and without. This is known as

Answer 1

Answer:

This is known as null effect

Step-by-step explanation:

A null effect is the outcome of an experiment that does not give the effect or result expected. Although an experiment with a null effect has a result, however the result of the experiment does not support the hypothesis

An example of a null result that remains importantly useful is the Michelson-Morley experiment from that partly made possible the formulation of special relativity theory

Two towns tracked the attendance at their summer fairs in 2016 and 2017. The data for each town and year is shown below. Year Ogdenville North Haverbrook 2016 960 500 2017 1008 540 What was the difference between the percent increases for each town from 2016 to 2017?

Answers

Answer:

48 and 5%; 40 and 8%

Step-by-step explanation:

The computation of the difference between the percentage increase for each town from 2016 to 2017 is given below:

Year Ogdenville North Haverbrook

2016 960 500

2017 1008 540

So here the difference would be

For 2016 to 2017

= 1008 - 960

= 48

The percentage increase is

= 48 ÷ 960

= 5%

And,

= 540 - 500

= 40

And, the percentage increase is

= 40 ÷ 500

= 8%

B. 5x2 +1
O C. 5x® - X-1
D. 5x4 - 2

Answers

Answer: Choice A) 5x^3 - x - 3

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

Work Shown:

We subtract the two functions like so

(f - g)(x) = f(x) - g(x)

(f - g)(x) = ( 5x^3-2 ) - ( x+1 )

(f - g)(x) = 5x^3 - 2 - x - 1

(f - g)(x) = 5x^3 - x - 3 ..... choice A

Note: be sure to remember to distribute the negative to every term inside (x+1), and not just to the x only.

then you cross multiply

so 8(2x-1) = 16x-8

and 20*6 = 120

then you do 120= 16x-8

add 8 to both sides (you want x by it's self so to get rid of a -8 you have to add 8)

128= 16x

(divide both sides by 16)

128/16= 8

Express the following equation in the form ax^2+bx+c=0:
(4a+3)^2=(a+5)(a−2)

Answers

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

15a² + 21a + 19 = 0

B. 16 x squared y squared + 9 z squared, a perfect square trinomial
C. 16 x squared y squared minus 24 x y z + 9 z squared, the difference of squares
D. 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial

Answers

Answer:

The answer is option D

Step-by-step explanation:

When factored out option C and D are the same but it is a perfect square, not the difference of squares.

Option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.

What is an algebraic expression?

An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.

For the given situation,

The expression is (4xy-3z)^2.

This expression can be expand by using the formula,

[tex](a-b)^{2} = a^{2} -2ab+b^{2}[/tex]

Here, a = 4xy and b = 3z

⇒ [tex](4xy)^{2} -2(4xy)(3z)+(3z)^{2}[/tex]

⇒ [tex]16x^{2} y^{2} -24xyz+9z^{2}[/tex]

Hence we can conclude that option (D) 16 x squared y squared minus 24 x y z + 9 z squared, a perfect square trinomial is the correct answer.
