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?

Answer:

  see below

Step-by-step explanation:

The exponent rules that apply are ...

  (a^b)(a^c) = a^(b+c)

  a^-b = (1/a)^b

  (a^b)^c = a^(b·c)

_____

These let you rewrite the given function as ...

  f(x) = (3^(2x))(3^1) = 3(3^(2x)) = 3(3^2)^x = 3·9^x

and

  f(x) = 3^(2x+1) = (3^-1)^(-(2x+1)) = (1/3)^-(2x+1)

Figure ABCD is transformed to obtain figure A′B′C′D′:
Kisachek [45]

Step-by-step explanation:

part A:

ABCD is transformed to obtain figure A′B′C′D′:

1) by reflection over x-axis, obtain the image :

A(-4,-4) B(-2,-2) C(-2, 1) D(-4, -1)

2) by translation T (7 0), obtain the image :

A'(3,-4) B'(5,-2) C'(5, 1) D'(3, -1)

part B:

the two figures are congruent.

the figures that transformed by reflection either or translation will obtain the images with the same shape and size (congruent)

How do you solve this problem
lora16 [44]
X² = 17

To simplify this, you need to find the square root of x², which is x, and the square root of 17.

x = √17
Also remember that when you are using square root, the answer can be either positive or negative.

x = +/-√17 ≈ +/- 4.12
