D) y=-6

Step-by-step explanation:

pass the positive 24 to the other side of the equal sign, but the positive sign changes into negative. Keep the 6y there. Then you need to combine the numbers if their sign is the same you add them up and keep the sign, so in this case is gonna be (-36). After that, you need to divide by 6 because you want the y isolated. The answers is D) y= -6

Answer:

D. = -6.

Step-by-step explanation:

-12 = 24 + 6y Subtract 24 from both sides:

-12 - 24 = 6y

-36 = 6y Divide both sides by 6:

y = -36/6

y = -6.

Un número desconocido es multiplicado por 11 y a este resultado se le resta 24. El resultado de esta operación es 86. Escribe en

Answer: The number is 10.

Step-by-step explanation:

Let x be the required number.

Given: 11 is multiplied to the number then 24 is subtracted from that and the result is 86.

The mathematical statement for the given situation,

11x -24 = 86

To solve the equation, Add 24 on both sides , we get

11x - 24 +24 = 86+24

⇒ 11x = 110

Divide both sides by 11, we get

x = 10

hence, the number is 10.

Minimize Q=3x2+3y2, where x+y=6.

weeeeeb [17]

Answer:

$+(x + y) {}^{2} = 6 {}^{2} \\ x {}^{2} + 2xy + y {?}^{2} = 36$

$x {}^{2} + y {}^{2} = 36 - 2xy$

$q = 3(x {}^{2} + y {}^{2} )$

$q = 3(36 - 2xy) = 108 - 6xy$

The manager of the motor pool wants to know if it costs more to maintain cars that are driven more often. Data are gathered on e

Liula [17]

Answer:

b. There's no statistically significant linear relationship between the number of miles driven and the maintenance cost

Step-by-step explanation:

The p-value for the slope estimate show us how strong is the certainty that there are a linear relationship between both variables. In this case, the p-value for the slopes shows if there is a significant relationship between the number of miles driven and the maintenance cost.

If we have a high p-value like 0.7 we can said that there is no certainty in the linear relationship. it means that there's no statistically significant linear relationship between the number of miles driven and the maintenance cost.
