Answer:
0.0958
Step-by-step explanation:
Percentage involved in accident = 8% = 0.08
Number of drives selected = 14
Probability that 3 or more who were involved in a car accident last year?
P(x>=3) = P(x=3) or P(x>3)
Similarly;
P(x>=3) = 1-P(0<= x <=2)
P(x>=3) = 1-P(0<= x <=2)
Using the binomial probability calculator :
Cummulative probability :
P(X >= x) = 0.09583481948
= 0.0958
Answer:
C. 6x² -45x + 21
Step-by-step explanation:
( x - 7) (6x - 3)
= x(6x - 3) -7 ( 6x - 3)
= 6x² - 3x - 42x + 21
= 6x² - 45x + 21

Answer:
Option D)
The items have same y-intercepts and different rates of change.
Step-by-step explanation:
<h3>y = mx + c </h3>
is the equation of straight line
here m is the gradient and c is the y intercept
First equation given in the question:
<h3>
y = 1.5x + 3.5</h3>
Construction of second equation
m = y2-y1 / x2 - x1
= 2.5 - 1.5 / -1+2
= 1
y = mx + c
1.5 = (-2) + c
c = 3.5
So the second equation will be
<h3>
y = x + 3.5 </h3>
