Super Cola is considering a recipe change. There are two recipes under development: a sugary, sweet cola and a less sugary, mild

cola. Researchers from Super Cola must determine whether consumers are more or less likely to buy the sweet cola or the mild cola. The researchers realize that the subjects might not like a less sweet cola after drinking a sweeter cola and vice versa. How should the researchers decide which cola should be tasted first?
A. The researchers should flip a coin once and use the winning cola first on every subject, for experimental consistency.
B. There should be only one cola tested per experiment to avoid confusing the consumers.
C. The researchers should flip a coin to decide independently for each subject, to randomly assign the cola recipe for each subject.
D. The sweet cola should always be tasted first because it will give the consumers a relief when they taste the mild cola.
E. The mild cola should always be tasted first because no one would like it after the sweet one.

Answer:

Option C is the correct answer.

Step-by-step explanation:

There are two recipes under development: a sugary, sweet cola and a less sugary, mild cola.

Researchers from Super Cola must determine whether consumers are more or less likely to buy the sweet cola or the mild cola.

As the researchers realize that the subjects might not like a less sweet cola after drinking a sweeter cola so, they should decide which cola should be tasted first by - flipping a coin to decide independently for each subject, to randomly assign the cola recipe for each subject.

In this method they can fix, that if heads comes, the subject has to drink the mild one and if tails come, then he has to drink the sweet one.

Options D and E are irrelevant. Option B will be a biased survey.

An expression is shown below. Which expression is equivalent to the expression shown?
Vera_Pavlovna [14]

Note: In option A, it should be "+" instead of "(".

Given:

The expression is

-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)

To find:

The equivalent expression.

Solution:

We have,

-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)

Using distributive property, we get

=-2x(x)-2x(y)-2x(-3)+3(-x)+3(4y)+y(3x)+y(5y)+y(-3)

=-2x^2-2xy+6x-3x+12y+3xy+5y^2-3y

On combining like terms, we get

=-2x^2+5y^2+(-2xy+3xy)+(6x-3x)+(12y-3y)

=-2x^2+5y^2+xy+3x+9y

The expression -2x^2+5y^2+xy+3x+9y is equivalent to the given expression.

Therefore, the correct option is A.

(10+-7 - -2) / (-2 - -1)
Scrat [10]

Nice use of brackets. We know exactly what you mean.

(10 - 7 + 2) / (-2 + 1) Notice that with an even number of - signs, you get a plus and with and odd number you get a minus.

(5) / (-1) = - 5 answer

Edit

Numerator

10 does not change.

+ - 7 Here a plus and a minus are put together. There is 1 minus sign which is an odd number of minus signs so the 7 is minus

- - 2 Here there are 2 minus signs. They become plus because 2 is even, and an even number of minuses become a plus so you have +2

10 - 7 + 2 = 5

Denominator

-2 does not change. It remains minus 2.

- - 1 There are 2 minus signs so this becomes plus 1.

- 2 + 1 = - 1

Numerator over denominator = 5/-1 = - 5. I'll probably run out of editing time. If you still don't understand, try and pinpoint the problem and we'll keep trying until you do see it. This question is worth it.
