Using data from a study, we find a significant difference in the proportion of fruit flies surviving after 13 days between those

eating organic potatoes and those eating conventional (not organic) potatoes. This exercise asks you to conduct a hypothesis test using additional data from this study.1 In this case, we are testingH0:po=pcHa:po>pcwhere po and pc represent the proportion of fruit flies alive at the end of the given time frame of those eating organic food and those eating conventional food, respectively. We have n1=n2=500. Show all remaining details in the test, using a 5% significance level.Effect of Organic Raisins After 15 DaysAfter 15 days, 320 of the 500 fruit flies eating organic raisins are still alive, while 300 of the 500 eating conventional raisins are still alive.Give the test statistic and the p-value.Round your answers to three decimal places.What is the conclusion?Do we have evidence that the proportion surviving after eating organic is higher?

What is negative 6x squared take away 586 =84x take away 4
olchik [2.2K]

Answer:

This equation has no real roots

Step-by-step explanation:

We want to solve

- 6 {x}^{2}  - 586 = 84x - 4

We group all terms on the left:

- 6 {x}^{2}  - 84x - 586 + 4 = 0

- 6 {x}^{2}  - 84x - 582= 0

Divide through by -6

{x}^{2}  + 14x + 97 = 0

The discriminant is

{14}^{2}  - 4 \times 1 \times 97 =  - 192

This means the given equation has no real solution, since the discriminant is less than 0

Which product is negative?
Nataliya [291]

Answer: -3.4.(-2) • (-2)= -48

Step-by-step explanation: please keep in mind that every number that you multiply by 0 is equal to 0, it does not mind if number is positive or negative the result will be always 0, if we have this clear we can pass with following step.

then you do not need resolve the equation with 0 because you know that result will be 0, after that we get only one equation the first one.

-3 * 4 * (-2) * (-2)

keep in mind when you are multiplying numbers with the same sign the product will be positive, but when you are multiplying numbers with different signs the result will be negative.

we can resolve this value by value for example

-3 * 4 * (-2) * (-2)

-3 * 4= -12

then we get the following equation

-12 * (-2) * (-2)

then we can pass with the next value

-12 * (-2) = 24

then we get the following equation

24 * (-2) = -48

as you can see this will be the only one equation with a negative product.
