What is the value for y

Dahasolnce [82]

Answer:

y = -2/5x + 24

Step-by-step explanation:

(5y + 10) + 2x + 50 = 180

5y + 2x + 60 = 180

5y + 2x = 120

5y = -2x + 120

y = -2/5x + 24

Original shirt cost: $55. Current shirt cost $40 find the percent decrease round to the nearest whole percent

ioda

Answer:

Step-by-step explanation:

Original cost = $55

Current price = $40

Decrease in price = 40-55 = -$15

Percentage decrease = [(New price - old price)/ old price] *100

Percentage decrease = (40-55)/55] *100

= -0.272727 *100

= -27.27%

To a whole percentage = 27%

Therefore, the cost of the t-shirt decreased by 27%

Let X have the probability mass function P(X = −1) = 1 2 , P(X = 0) = 1 3 , P(X = 1) = 1 6 Calculate E(|X|) using the approaches

Studentka2010 [4]

Answer:

Step-by-step explanation:

From the given information:

Note that the possible values of Y are 0 and 1 because;

y = 0 if X = 0 and y = 1 if X = ±1

∴

$P(Y =0) = P(X = 0) =\dfrac{1}{3}$

$P(Y = 1) = P(X = -1 \ or \ 1) \\ \\ = P(X = -1) + P(X = 1)$

$= \dfrac{1}{2}+ \dfrac{1}{6}$

$=\dfrac{3+1}{6}$

$= \dfrac{2}{3}$

$E(|X|) = \sum |x| P(X=x) = ( 1 \times \dfrac{1}{2}) + ( 0\times \dfrac{1}{3}) + ( 1 \times \dfrac{1}{6})$

$= \dfrac{2}{3}$
