faltersainse [42]

Answer:

$\left\{\begin{matrix}39 & x\leq 200\\ 39+(x-200)\times 0.35 & x>200\end{matrix}\right.$

Step-by-step explanation:

We are given that Ben has a cell phone plan that provides 200 free minutes each month for a flat rate of $39.

We are also told that For any minutes over 200, Ben is charged $0.35 per minute.

let x be the minutes used each month

So, if $x\leq 200$

So, coat will be $39

If $x>200$

So, Ben is charged $0.35 per minute

So, when $x>200$

So, charge = $39+(x-200)\times 0.35$

So, the piecewise functions accurately represents charges based on Ben's cell phone :

$\left\{\begin{matrix}39 & x\leq 200\\ 39+(x-200)\times 0.35 & x>200\end{matrix}\right.$

Does the ordered pair, (1, 5/2) satisfies the given equation 3x-3y=-3 ?

vampirchik [111]

Answer:

Ordered pair, (1, 5/2) does not satisfy the given equation 3x-3y=-3

Step-by-step explanation:

$3x-3y=-3$

Here $(x, y) = (1, \frac{5}{2} )$

$3(1)-3(\frac{5}{2} )=-3$

$3- (\frac{15}{2} )=-3\\6-15=-6\\-9\neq -6$

5. Two unbiased dice are rolled. Calculate the probability that the sum of the two dice is:

IceJOKER [234]

The sample space has 36 possible pairs from 1,1 1,2 1,3 up to 6,5 and 6,6

(a). Three pairs add to 4 1,3 2,2 and 3,1 so P(4) = 3/36 = 1/12

(b). 6 pairs add to 7 so P(7) = 6/36 = 1/6

(c) 15 pairs add to less than 7 so P(<7) = 15/36 = 5/12
