Help!! Please!!!!!

Mathematics
1 answer:
VLD [36.1K]3 years ago
4 0

Answer:

the mean is 8 and the absolute deviation is 1.5

Step-by-step explanation:

to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!

MA_775_DIABLO [31]

Answer:

y = .025x +20

The y intercept is the value when x = o, or the starting value.  In this case, it is the temperature in degrees F at a depth of 0 meters.

Step-by-step explanation:

We have a point a (0,20) and a point at (2 , 20.05)

We can find the slope from

m = (y2-y1)/(x2-x1)

   = (20.05-20)/(2-0)

   = .05/2

     =.025

One of the points (0,20) is the y intercept  since x=0

We can use the slope intercept form of the equation

y= mx+b

y = .025x +20


The y intercept is the value when x = o, or the starting value.  In this case, it is the temperature in degrees F at a depth of 0 meters.

Write an inequality that represents the missing dimension x
forsale [732]

For this case we have that by definition, the area of a rectangle is given by:

A = a * b

Where:

a, b: They are the dimensions of the rectangle.

In the statement we are told that "The area is greater than 12 square inches", then:

A> 12

Also we have:

a = 2\\b = x

Substituting we have:

2x> 12

Dividing between 2 on both sides:

x> \frac {12} {2}\\x> 6

Finally we have:

x> 6

ANswer:

x> 6

A travel agent is booking trips for tourists who travel from New York to Chicago. Tourists have three choices for how to travel
sashaice [31]

Answer:

P = 1/2

Step-by-step explanation:

If the tourist spends more than 275$, they must not arrive in Chicago by bus.

( 150 + 60 < 275, 150 + 40 < 275)

The total options the tourist can make:

3 x 2 = 6

(1st leg: 3 possible options, 2nd leg: 2 possible options)

The number of options the tourist can make after excluding bus option:

2 x 2 = 4

(1st leg: 2 remaining possible options, 2nd leg: 2 possible options)

The number of options the tourist can make after excluding the bus option and spend more than 275$:

4 - 1 = 3

(excluding the case of selecting train and cab, because 225 + 40 < 275)

=> The probability that the tourist will spend more than 275$ on these 2 legs of the trip:

P = 3/6 = 1/2

PLEASE HELP ME WITH THIS<br><br>​
Vladimir [108]

Answer:

A. (0, 60)

B. 15x

Step-by-step explanation:

The initial value is the same as the y-intercept, which is 60 or (0, 60).

The rate of change would be the same as the slope. To find the slope, you do rise/run. You move 15 units up, and 1 to the right. That would be 15x.

Hope this helps!
