Answer:
4 1/2
Step-by-step explanation:
We use the formula d = rt where d = distance, r = rate, t = time
Equation for Sam:
Equation for Sam's father:
d = (12)(t - 0.33)
d = 12t - 4
Since Sam and his father have the same distance from their home to Sam's school, then
2t = 12t - 4
4 = 12t - 2t
4 = 10t
4/10 = t
t = 0.4 hrs or 24 mins
Sam travel 24 mins from home to school and his father travel 4 mins from home to school. Therefore, it was about 8:24 when Sam's father give the project to Sam.
Answer:
The required probability is 0.9916
Step-by-step explanation:
Consider the provided information.
If 45% of cars are traveling in excess of 70mph,
Therefore, p = 0.45
q = 1-p = 1-0.45 = 0.55
8 random cars are measured via radar: n = 8
We need to find at least 1 car is going over 70mph.
According to binomial distribution:
We need to find P(X≥1)
Hence, the required probability is 0.9916
I remember this but I dead forgot how to do it
Answer: y intercept (0|0)
x intercept (0|0)
Step-by-step explanation:
Y intercept means x=0
y=3*0
y=0. So the point is (0|0)
X intercept means y=0
0=3x
X=0. So the point is also (0|0)
