Klio2033 [76]3 years ago
3 0

Answer:

MAD = 0

Step-by-step explanation:

When I calculated this by hand I got 0. To find the MAD:

1. You first need to find the mean of the numbers.

4 + 5 + 8 + 8 + 10 = 35

35/5 = 7

the mean value = 7

2. Then you must find the absolute value of the difference between each data value and the mean: |data value – mean|

(4 - 7) = -3

(5 - 7) = -2

(8 - 7) = 1

(8 - 7) = 1

(10 - 7) = 3

3. Add the difference values up

(-3) + (-2) + 1 + 1 +3 = 0

4. Divide the sum of the absolute values of the differences by the number of data values.

0/5 = 0

A bicycle lock has a four-digit code. The possible digits, 0 What is the probability that the lock code will begin with
nika2105 [10]

Answer:

0.1-0.6

Step-by-step explanation:

First let's find the number of the elements in the sample space, that is the total number of codes that can be produced.

The first digit is any of {0, 1, 2...,9}, that is 10 possibilities

the second digit is any of the remaining 9, after having picked one. 

and so on...

so in total there are 10*9*8*7 = 5040 codes.

a. What is the probability that the lock code will begin with 5?

Lets fix the first number as 5. Then there are 9 possibilities for the second digit, 8 for the third on and 7 for the last digit.

Thus, there are 1*9*8*7=504 codes which start with 5.

so 

P(first digit is five)=

b. What is the probability that the lock code will not contain the number 0? 

from the set {0, 1, 2...., } we exclude 0, and we are left with {1, 2, ...9}

from which we can form in total 9*8*7*6 codes which do not contain 0.

P(codes without 0)=n(codes without 0)/n(all codes)=(9*8*7*6)/(10*9*8*7)=6/10=0.6

Answer:

0.1 ; 0.6

What are the coordinates of the terminal point determined by t=20pi/3?
attashe74 [19]

Answer:

(- 1/2 , √3/2)

Step-by-step explanation:

t=20π/3

t' = 20π/3 - 6π = 2π/3   (120°) ... 2nd quadrant

If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)

OF/OE = - cos 60° = x / 1 =  - 1/2

FE/OE = sin 60° = y/1  = √3/2
