What does 15÷14 equals to

Answer:

the probability that none of the boxes have more than 6 balls is 0.3077

Step-by-step explanation:

Given that;

12 balls are put into 3 boxes randomly, without ay condition

so we will be using the multinomial formula;

⇒ [ 12 + 3 - 1              [ 14

        3 - 1 ]         =       2 ]    =    91

now, assuming that one of the box has more than 6 balls that is at least 7 balls

x + y + z = 12

 x + y + z = 7

therefore

x + 7 + y + z = 12

x + y + z = 5

therefore the number of the solution here computed as;

⇒ [ 5 + 3 - 1              [ 7

        3 - 1 ]         =       2 ]    =   21

Hence, the probability that none of the boxes have more than six (6) balls will be;

= (91 - (3 × 21)) / 91

= (91 - 63) / 91

= 28 / 91

= 0.3077

Therefore the probability that none of the boxes have more than 6 balls is 0.3077

Answer:

The slopes are neither perpendicular nor parallel.

Step-by-step explanation:

First we are going to find the slope-inercept form from the equation, -2x + 10y = 5.

Solve for y.

-2x + 10y = 5

+2x. = +2x

10y = 2x + 5

[tex]\begin{gathered} \frac{10y}{10} = \frac{2x + 5}{10} \\ y = \frac{1}{5}x + \frac{1}{2} \end{gathered}[/tex]

So we now have

[tex]\begin{gathered}y = \frac{1}{5}x + \frac{1}{2} \\ and \\ y = - \frac{1}{5} x + 6 \end{gathered}[/tex]

Looking at the equation above, the slopes are neither perpendicular nor parallel.

Answer:

-16

Step-by-step explanation:

-8 X positive 2  

Answer:

-16

Step-by-step explanation:

When you multiply a negative number with a positive number, the result would be a negative number.

-8 × -2 = -16

The algebraic expression for the situation -4 less than a number is 17 are n -4 = 17

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

We are given that -4 less than a number is 17.

Let the number be n.

So, -4  less than a number means;

n - 4

Also, n - 4 = 17

Solving the equation we get;

n = 21

Therefore, The algebraic expression for the situation -4 less than a number is 17 are n -4 = 17

Answer:

y-9=2x

Step-by-step explanation:

The reason it is y-9=2x is because y=22+9 is y=31 and you have 5 to give so 5=31 which is not correct.

Answer:

A(n)=250+(n-1)(0.03*250);$347.50

The required explicit formula that represent the account's balance at the beginning of year 14 is  given as Amount = 250(1 + 0.03(n - 1)).

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.

Here,
Balance after 1 year of deposit is given by,
Amount = principal(1 + r%)
Amount = 250(1 + 0.03)

Now,
at the end of the n years, Amount is given as,
Amount = 250 ( 1 + 0.03n)

Now. At the starting of the nth year, amount is given as,
Amount = 250(1 + 0.03(n - 1))

Now, put n = 14 in above formula,
Amount = 250(1 + 0.03(14 - 1))
Amount = 4347.5

Thus, The required explicit formula that represent the account's balance at the beginning of year 14 is  given as Amount = 250(1 + 0.03(n - 1)) ,

Answer:

1,500

Step-by-step explanation:

Remember that in a cost function, the cost per item is multiplied by x and the fixed cost is the part of the equation that is not multiplied by anything.

Cost = (Cost per item)(x) + Fixed cost

C(x) = 90x + 1,500

As you can see:

(Cost per item) would be 90

x would be, well x.

The fixed cost would be 1,500.

Answer:

x=2

Step-by-step explanation:

10x+14 = -2x+38  add 2x to both sides

10x +2x +14 = -2x +2x +38

10x +2x +14 = 38 subtract 14 from both sides

10x +2x +14 -14 = 38 -14

10x +2x = 38 -14 combine like terms

12x = 24 divide both sides by 12

12x/12 = 24/12

x =2

Answer:

x = -2

Step-by-step explanation:

10x + 14 = -2x + 38

Subtract 14 from both sides:

10x + 14 - 14 = -2x + 38 - 14

10x = -2x - 24

Add 2x to both sides

10x + 2x = 2x - 2x - 24

12x = -24

Divide both sides by 12

12x/12 = -24/12

x = -2
