Look at the part of the function after the commas. That tells you which function to use. -2 is less than 1, so use the top function

f(-2) = 3(-2)² - 1 = 11

Find P(organic | oranges)<br> Find P(Non-organic | oranges)
Reika [66]
Answer to part A: 0.63
Answer to part B: 0.37
Answer to part C: organic oranges

---------------------------------------------------------------------
---------------------------------------------------------------------

Work Shown:

Part A
P(Organic|Oranges) = P(Organic AND oranges)/P(Oranges)
P(Organic|Oranges) = 0.19/0.30
P(Organic|Oranges) = 0.63

Part B
P(Non-organic|Oranges) = P(non-organic AND oranges)/P(oranges)
P(Non-organic|Oranges) = 0.11/0.30
P(Non-organic|Oranges) = 0.37

Part C
The probability in part A is larger compared to the answer in part B, so it's more likely to have someone pick organic oranges rather than non-organic oranges. Melina should restock organic oranges for the next sale.

Deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?
slavikrds [6]

deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?​

REmember that

The range of a set of data is the difference between the highest and lowest values in the set

If U is the highest value

Range=U-38

range=10

so

10=U-38

U=10+38

U=48

If U is the lowest value

Range=47-U

10=47-U

U=47-10

U=37

therefore

U coulbe between 48 and 37

Given a mean of 61.2 and a standard deviation of 21.4 what is the z score of the value 90 rounded to the nearest tenth?
Nitella [24]

Answer:

The z-score of 90 is 1.35

Step-by-step explanation:

The z-score is calculated using the formula:

z =  \frac{x -  \mu}{ \sigma}

From the question, it was given that the mean is

\mu = 61.2

and the standard deviation is

\sigma = 21.4

and x=90.

We substitute the given values to obtain:

z =  \frac{90 - 61.2}{21.4}

z =  \frac{28.8}{21.4}  = 1.35

Observa las dimensiones del siguiente portarretrato, y escribe la expresión que determina el área disponible para la fotografía
777dan777 [17]

Answer:

<h2>D</h2>

Step-by-step explanation:

The dimensions of the portrait are attached.

The total area of the portrait is represented by its width 5+x and its length x+1.

We know by definition that the area of a rectangle is

A= w \times l

Where w is the width and l is the length.

Using the given expressiones, we have

A=(5+x)(x+1)=5x+5+x^{2} +x=x^{2} +6x+5

Therefore, the right answer is D.
