Long’s Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month,
dem82 [27]

Answer: 12 refills

Step-by-step explanation:

y = 8.95 + 1.50x

26.95= 8.95 + 1.50x

26.95 - 8.95 = 1.50x

18 = 1.50X

18 / 1.50 = x

X = 12

Solve the quadratic equation by completing the square.<br> x^2+12x+52=0
White raven [17]

Answer:

(x + 6)² + 16 = 0

Step-by-step explanation:

To complete the square we will first need to get our equation to look like: x² + bx = c

Here we have x² + bx + c = 0 → x² + 12x + 52 = 0

  • First we need to subtract our c, in this case 52, from both sides to get x² + 12x = -52
  • We then need to add (\frac{b}{2} )^{2} to both sides of the equation
  • Here our b value is 12, so plugging this into our formula we get (\frac{12}{2} )^{2} =(6)^{2} =36
  • Adding 36 to both sides our equation becomes: x² + 12x + 36 = -52 + 36
  • Then combining like terms on the right side we get x² + 12x + 36 = -16
  • Now making our left side of the equation into a perfect square we get: (x + 6)² = -16
  • Finally adding the 16 to both sides of the equation we get: (x + 6)² + 16 = 0

anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, and teh probability that it is canvas is
harkovskaia [24]

The probability that it is pink or canvas is 0.9

Step-by-step explanation:

Let us revise the meaning of "or" , "and" on probability :

  • The use of the word "or" means that you are calculating the probability  that either event A or event B happened.  Both events do not have to happen
  • The use the word "and", means that both event A and B have to happen

The addition rules are:

  • P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen  at the same time)
  • P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they  have at least one outcome in common)

Anna is shopping for a new backpack

∵ The probability that the backpack is pink is 0.7

∴ P(pink) = 0.7

∵ The probability that it is canvas is 0.7

∴ P(canvas) = 0.7

∵ The probability that it is pink and canvas is 0.5

∴ P(pink and canvas) = 0.5

Substitute the values above in the rule below

∵ P(pink or canvas) = P(pink) + P(canvas) - P(pink and canvas)

∴ P(pink or canvas) = 0.7 + 0.7 - 0.5

∴ P(pink or canvas) = 0.9

The probability that it is pink or canvas is 0.9
