I believe the answer is 5t
6s7t-6s2t = 5t
Answer:
In which x is the number of which we want to find the probability.
Step-by-step explanation:
For each traffic fatality, there are only two possible outcomes. EIther it involved an intoxicated or alcohol-impaired driver or nonoccupant, or it didn't. Traffic fatalities are independent of other traffic fatalities, which means that the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
The probability is .40 that a traffic fatality involves an intoxication or alcohol-impaired driver or nonoccupant.
This means that
Eight traffic fatalities
This means that
Find the probability that the number which involve an intoxicated or alcohol-impaired driver or nonoccupant is
This is P(X = x), in which x is the number of which we want to find the probability. So
Domain is how far left or right the numbers go on the number line for that graph
I answerd this yesterday I think
g(x) starts at -inifinity and ends ata bout x=2, so it doesn't have all real numbers
f(x) starts at about -4 and ends at abot infinity, doesn't have all real number
p(x) is a veritical line, we know that lines have domain as all real number
only p(x)

Answer:
t = 1 3/7 hours
Step-by-step explanation:
For plane 1
distance = rate *t
d1 = 40 *t
For plane 2
distance = rate * time
d2 = 100 * t
We know that d1+d2 = 200 (the planes will meet)
We know that the times will be the same because the leave at the same time.
Substitute in d1 =40t and d2 = 100t into d1+d2 = 200
d1+d2 = 200
40t + 100t = 200
Combine like terms
140t = 200
Divide each side by 140
140t/140 = 200/140
t= 200/140
t= 20/14
t = 10/7
t = 1 3/7 hours
the money given by joe to hector is 125$
let the hector works for x weeks,
it is given that hector earns 50$ in a week,
so the total money hector wants to save is 1100$
now
from the above inequality, we will find x
it means the hector will work for 20 weeks in order to earn 1100$.
