Suppose that a jewelry store tracked the amount of emeralds they sold each week to more accurately estimate how many emeralds to
denpristay [2]

Answer: The point estimate for the mean is <u>2.59</u> and the margin of error is <u>0.13</u> .

Step-by-step explanation:

The confidence interval for population mean is given by :-

\mu\pm E, where E is the margin of error .

Given : At the end of one year, the store used the weekly sales information to construct a 95% confidence interval for the mean number of emeralds sold per week.

The confidence interval they calculated was (2.46,2.72) .

The lower limit of the confidence interval : \mu-E=2.46                 (1)

The upper limit of the interval :  \mu+E=2.72                                 (2)

Adding (1) and (2) , we get

2\mu=5.18\\\\\Rightarrow\mu=2.59

Now, Subtracting (1) from (2) , we get

2E =0.26\\\\\Rightarrow\ E=0.13

Hence, the point estimate for the mean is 2.59 and the margin of error is 0.13 .

Una empresa exportadora de frutas vende dos variedades de frambuesas: estándar y de lujo. Una caja de freses estándar se vende e
aksik [14]

Answer:

83.33 cajas estándar de frambuesas y 51.67 cajas de lujo de frambuesas.

Step-by-step explanation:

Representemos el número de cajas como

A = caja estándar de frambuesas

B = caja de lujo de frambuesas

Caja estándar de frambuesas = $ 7 Caja de lujo de frambuesas = 10.

A + B = 135 ......... Ecuación 1

B = 135 - A

7A + 10B = 1100 ........... Ecuación 2

Sustituir

135 - A para B en la ecuación 2

7A + 10 (135 - A) = 1100

7A + 1350 -10A = 1100

7A - 10A = 1100-1350

-3A = - 250

A = 250/3

A = 83.33 cajas

Sustituye 83.33 por A en la ecuación 1

A + B = 135

83,33 + B = 135

B = 135 - 83.33 = 51.67 cajas

Por lo tanto, vendió,

83.33 cajas estándar de frambuesas y 51.67 cajas de lujo de frambuesas.

M is the midpoint of AB. If the coordinates of A are (-1,5), and the coordinates of M are (3,3), what are the coordinates of B?
borishaifa [10]

Answer:

B = (5, 1).

Step-by-step explanation:

From the formula for the midpoint of  a line :-

(-1 + x)/2 , (5 + y)/2 = (6/2, 6/2)    where x and y are the coordinates of B.

so (-1 + x)/2 = 6/2

-1 + x = 6

x = 5.

and (5 + y)/2 = 6/2

5 +  y = 6

y =  1.
