Answer: y=2

Step-by-step explanation:

Combine like terms (2+13)

-20y+15=13-19y

Subtract 13 on each side

-20y+2=-19y

Isolate the variable by adding 20y on both sides

y=2

A number cube is rolled.what is the probability of rolling a number greater than 4​
frosja888 [35]

Answer: 2/6

Step-by-step explanation:

There’s only 2 numbers greater than 4 on a die, so two would be the numerator and the denominator would be the number of possibilities you could roll, which is 1-6.

A diner asks patrons for their preference for waffles or pancakes and syrup or fruit topping.
prohojiy [21]

Answer:

P (Waffles | Syrup)\neq P(Waffles)

Step-by-step explanation:

From the table we have to:

Probability of syrup is 0.96

Probability of waffles and syrup is 0.32

P (Waffles | Syrup) = P (Waffles and syrup) / P (syrup)

So:

If this equality is met, the probabilities are dependent, if on the contrary

P (Wafles | Syrup) = P (Wafles) then are independent probabilities.

P (Wafles | Syrup) = 0.32 / 0.96 = 0.333 \neq 0.32

So we have to:

P (Waffles | Syrup)\neq P(Waffles)

The probabilities are dependent.

A shopper needs 48 hot dogs. The store sells identical hot dogs in 2 differently sized packages. They sell a six pack hot dog fo
Archy [21]

Answer:He should buy the six pack.

Step-by-step explanation:

The total number of hotdogs that the shopper needs is 48.

The store sells identical hot dogs in 2 differently sized packages. They sell a six pack hot dog for $2.10, and an eight pack of hot dog for $3.12.

If the shopper buys the six pack hot dog, he would need to buy 8 of it. The total cost would be

8 × 2.10 = $16.8

If the shopper buys the eight pack hot dog, he would need to buy 6 of it. The total cost would be

6 × 3.12 = $18.72

The 6 pack is cheaper than the eight pack. Therefore,

He should buy the six pack.

Help. The problem is in the picture
inn [45]

Answer:

The answer to your question is y = 2/3x + 4

Step-by-step explanation:

Data

Equation     y = 2/3 x + 5

New line = ?

Process

Two lines are parallel if the have the same slope. The slope is the coefficient of the x.

1.- Get the slope of the original line

                y = 2/3x + 5

   slope = 2/3

2.- Two find the equation of a parallel line we need to point I will use (0, 4)

Use the point slope formula

               y - y1 = m(x - x1)

               y - 4 = 2/3(x - 0)

               y - 4 = 2/3 x

              y = 2/3x + 4
