Answer:

c = 1 btw can i be brainiest...

Step-by-step explanation:

First, rewrite the left side of the equation and group and combine like terms:

c + (4 − 3c) − 2 = 0

c + 4 − 3c − 2 = 0

−3c + c + 4 − 2 = 0

−3c + 1c + 4 − 2 = 0

(−3 + 1) c + (4 - 2) = 0

−2c + 2 = 0

Next, subtract

2

from each side of the equation to isolate the

c

term while keeping the equation balanced:

−2c + 2 − 2 = 0

−2 − 2c + 0 = −2

−2c = −2

Now, divide each side of the equation by

−2

to solve for

c

while keeping the equation balanced:

−2c - 2 = −2 − 2

−2c − 2 = 1

c = 1

Por un pantalón y unos zapatos he pagado 126€. Si el precio del pantalón aumentara en un 14%,entonves sería el 75% del precio de
Viktor [21]

Responder:

Pantalón = 50 €

Zapatos = 76 €

Explicación paso a paso:

Total pagado por pantalón y zapatos = 126

Sea el precio del pantalón = p; zapatos = s

p + s = 126

1,14 p = 0,75 s

p = 0,75 s / 1,14

0,75 s / 1,14 + s = 126

(0,75 s + 1,14 s) / 1,14 = 126

0,75 s + 1,14 s = 143,64

1,89 s = 143,64

s = 143,64 / 1,89

s = 76

p + s = 126

P = 126 - s

P = 126 - 76

p = 50

A random sample of house sizes in major city has a sample mean of x¯=1204.9 sq ft and sample standard deviation of s=124.6 sq ft
ki77a [65]

Answer:

About 95% of house sizes that lie between 955.7 and 1454.1 sq ft .

Step-by-step explanation:

According to the empirical rule  about 68% of the data is within one standard deviation of the mean; about 95% of the data is within two standard deviations of the mean ; about 99.7% of the data is within three standard deviations of the mean.

We have given:

Sample mean : x¯=1204.9 sq ft

Standard deviation: s=124.6 sq ft

To find the percentage of house sizes that lie between 955.7 and 1454.1 sqft.

We can write it as

955.7= 1204.9 - 249.2 = 1204.9 - 2(124.6)

and 1454.1  = 1204.9 + 249.2 = 1204.9 + 2(124.6)

Thus, 955.7 is 2 standard deviations left from the means and 1454.1 is 2 deviations right from the mean.

Then by empirical rule , about 95% of house sizes that lie between 955.7 and 1454.1 sq ft .
