Answer:
a=3,b=0,c=5,d=-4/21
Step-by-step explanation:
The formule we use to get the slope is:
m =
a. (3,2);(4,x); m=1
→ x= (1)(4-3)+2 → 3
b. (b,-1);(2,-2); m=-1/2
→ -1= (
)(2-b) →
→ 0
c. (5,d);(9,2); m=-3/4
→ d= (
)(9-5)-2 → 5
d. (-1/3,3/4);(h,5/6); m=7/12
→
=
(
) →
We get this equation with the original one:
y=mx+b
There are three forms of linear equations:
point-slope form y2-y1=m(x2-x1)
standard form Ax + By + C = 0 or Ax + By = C
and slope-intercept form y=mx+b
Answer:
0.397
Step-by-step explanation:
In the experiment, if the coin is flipped 4 times, the outcomes in which there is a single heads out of the 4 flips are:
HTTT,THTT,TTHT and TTTH
The probability of flipping a head, P(Head)=0.18
Therefore: The probability of flipping a tail, P(Tail)=1-0.18=0.82
We can then calculate the probability that there is a single heads out of the 4 flips
=P(HTTT)+P(THTT)+P(TTHT)+P(TTTH)
=(0.18 X 0.82 X 0.82 X 0.82) + (0.82 X 0.18 X 0.82 X 0.82) + (0.82 X 0.82 X 0.18 X 0.82 )+ (0.82 X 0.82 X 0.82 X 0.18)
