Answer:
m = y-b/x
Step-by-step explanation:
y = mx + b
0 = - y + mx + b
-mx = -y + b
m = -y + b / -x
m = y - b / x
Answer:
a) P(a)= 0.0001
b) P(b)= 0.0024
Step-by-step explanation:
Given:
Chosen number = 3079
Possible numbers that have chance of winning from 0000 to 9999= 10,000
Winning condition= if made choice matches the winning digits
Now
a)What is the probability that the winning number matches your number exactly?
From 0000 to 9999, only one time can the number 3079 can be the winning number, so
P(a)= 1/10000
= 0.0001
b)What is the probability that the winning number has the same digits as your number in any order?
Winning numbers from 0000 to 10000 that have same digits as 3079 are
4 x 3 x 2 x 1 = 24 ways
Following are the 24 numbers from 0000 to 9999 that have matching digits to 3079:
0379
0397
0973
0937
0793
0739
3079
3097
3970
3907
3790
3709
7039
7093
7930
7903
7390
7309
9073
9037
9370
9307
9730
9703
P(b)= 24/10000
=0.0024 !
Answer:
m<DBC=120°
Step-by-step explanation:
2x+x+90=180
3x=180-90
3x=90
x=30
m<DBC=x+90=30+90=120
The sum of two consecutive integers is -23.
Let the larger number = x
smaller number = x - 1
Sum = -23
=> x + x - 1 = -23
=> 2x - 1 = -23
=> 2x = -23 + 1 = -22
=> x = -22/2
=> x = -11
Larger number is -11
Under Daily flat rate, we would have 22 and 0.15x
Under Cost per mile, we would have 0.15
Under Number of Miles Driven, we would have x
