Answer:

The price of a game is $0.82x$

Step-by-step explanation:

Let

x ----> the list price of a game

Remember that

$100\%-18\%=82\%=82/100=0.82$

To find out the price of a game that's been discounted 18% off its list price, multiply the list price by the number 0.82

$(x)(0.82)=0.82x$

poizon [28]

Let x be the number of songs downloaded.
Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.
This cannot be more than 20, so we set this less than or equal to 20:
1.29x ≤ 20.

To solve this, we divide both sides by 1.29: 
 $\frac{1.29x}{1.29}$ ≤ $\frac{20}{1.29}$ ;
x ≤15.5.

We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.

Answer:

-25

Step-by-step explanation:

You must first pick two points. I picked the points of (4, 400) and (8, 300). You can pick different points and still get the right answer.

Subtract the y's and the x's. Divide the difference of y by the difference of x.

400 - 300 = 100

4 - 8 = -4

100/-4 = -25

The slope, or rate of change, is -25.

Answer:

Not true.

Step-by-step explanation:

Whole numbers are integers that are 0 or greater than 0. Since 0 is a whole number and x > 0 does not include 0, the statement is not true. Only the sign ≥ includes 0.

A box contains cards bearing numbers from 6 to 70. If one card is drawn at random from the box, find the probability that it bea

777dan777 [17]

Answer:

a) 4/65 b) 13/65 c) 12/65 d) 19/65

Step-by-step explanation:

Probability is the likelihood or chance that an event might occur.

Probability = expected outcome of event/Total outcome of event

If a box contains cards bearing numbers from 6 to 70, the total outcome will be the total number present from 6 to 70 which is 65

a) The amount of one digit number we have are 4 i.e {6,7,8,9}. This will be our expected outcome in this case.

The probability that the number drawn bears a one digit number will be 4/65

b) For numbers divisible by 5, the numbers that are divisible by 5 from the number drawn are {10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70}

The total expected outcome in this case = 13

The probability that the number drawn is divisible by 5 = 13/65

c) For odd numbers less than 30, they are {7,9,11,13,15,17,19,21,23,25,27,29}

The total expected outcome in this case = 12

The probability that the number drawn are odd numbers less than 30 = 12/65

d) For composite number between 50 and 70, this are numbers that are within this range and they includes {51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69}

The total expected outcome in this case = 19

The probability that the number drawn are composite numbers between 50 and 70= 19/65
