Since the two boxes are identical, we know that both of the boxes are of equal weight. Since one box weighs 168 ounces, the other weighs 168 too. So we add them together..
168 + 168 = 336

The total weight in ounces of the nails that Jason bought is 336 ounces.

seis manzanas y 8 peras cuestan $26. Cuánto cuesta xada pera y cada manzana sabiendo que cada manzana cuesta el triple de lo que

vodomira [7]

Con un sistema de ecuaciones, tiene-se que:

Cada pera cuesta $1.
Cada manzana cuesta $3.

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

Usando la información dada en el texto, se construye un<em> sistema de ecuaciones</em> para encontrar el precio de cada pera e de cada manzana.
Yo diré que el precio de cada manzana es x y de cada pera es de y.

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

<u>La compra de 6 manzanas y 8 peras cuesta $26</u>, lo que significa que una de las ecuaciones es:

$6x + 8y = 26$

<u>Cada manzana cuesta lo triple de cada pera</u>, lo que significa que la outra ecuacione es:

$x = 3y$

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

Aplicando esta relacion en la primera ecuación, se encontra el precio de cada pera.

$6x + 8y = 26$

$6(3y) + 8y = 26$

$26y = 26$

$y = \frac{26}{26}$

$y = 1$

Cada pera cuesta $1.

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

Para cada manzana:

$x = 3y = 3(1) = 3$

Cada manzana cuesta $3.

A market surveyor wishes to know how many energy drinks teenagers drink each week. They want to construct a 80% confidence inter

jasenka [17]

Answer:

The 80% confidence interval for the mean

(4.6199 , 4.7801)

Step-by-step explanation:

<u>Explanation</u>:-

Assuming that the population standard deviation for the number of energy drinks consumed each week is 1

Given the Population standard deviation 'σ' = 1

The study found that for a sample of 256 teenagers the mean number of energy drinks consumed per week is 4.7

given sample size 'n' = 256

mean of the sample 'x⁻' = 4.7

<u>confidence interval for the mean</u>

The 80% confidence interval for the mean is determined by

$(x^{-} -Z_{\alpha } \frac{S.D}{\sqrt{n} } , x^{-} + Z_{\alpha }\frac{S.D}{\sqrt{n} } )$

the z-score of 80% level of significance = 1.282

$(4.7 - 1.282\frac{1}{\sqrt{256} } , 4.7 + 1.282\frac{1}{\sqrt{256} } )$

(4.7 - 0.0801 , 4.7 +0.0801)

(4.6199 , 4.7801)

<u>Conclusion</u>:-

The 80% confidence interval for the mean

(4.6199 , 4.7801)

What is the inverse of the function? f(x)=3x−1

Hatshy [7]

Answer:

The inverse is 1/3 (x+1)

Step-by-step explanation:

y = 3x-1

Exchange x and y

x = 3y-1

Solve for y

Add 1 to each side

x+1 = 3y-1+1

x+1 = 3y

Divide each side by 3

(x+1)/3 = 3y/3

1/3(x+1) =y

The inverse is 1/3 (x+1)
