1.

List the scores:

(2) 60

(1) 65

(5) 75

(1) 95

(1) 100

Find the chart with those quantities: Chart A

2. Find the mean:

75 + 60 + 75 + 100 + 75 + 75 + 75 + 95 + 60 + 65 = 755

755/10 = 75.5

Subtract the mean from Ashley’s score:

60 – 75.5 = -15.5

The answer is D.

If you were to roll the dice one time what is the probability it will land on 4
vovangra [49]

Answer: 1/6

Step-by-step explanation: To find the probability of rolling a 4, let's use our ratio for the probability of an event which is shown below.

Number of favorable outcomes/total number of outcomes

Since only one side of a number cube has a 4 on it, the number of favorable outcomes for rolling a 4 is 1 and since there are six sides to a number cube and it's equally likely that the cube will land on any of these sides, the total number of outcomes is 6.

So the probability of rolling a 4 is 1/6 which is equivalent

to 0.167 or 16.7%.

That means it is't likely that you would roll a 4 for instance but it's just as likely as rolling any other number.

Answer:

y=1/2x-2

Step-by-step explanation:

perpendicular lines have a neg. reciprocal for the slope.

for example:

in this equation y=-2x+1

-2 is the slope and the negative reciprocal would be 1/2

hence, the slop of our new line is 1/2

y=1/2x+b

we can substitute the coordinates given for x and y:

2=1/2(8)+b

2=4+b

-2=b

hence the new equation is y=1/2x-2
