Answer:
5.209 or A
Step-by-step explanation
5^x-4=7
reserve 4
log sides
x-4 log5 and log7
x-4=log7/log5
+4 or number of your equation
x=log5/log7 +4
use calculator
get answer
5.209
EDIT: Got a 100 on the test this is correct
Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.
Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5
Therefore, we have:
Let x be the number calls that reach to live person.
We have to find
Using the binomial probability distribution, we have:
Therefore, the probability that none of them reaches a live person is 0.3277
Answer:
y+4 = 9/4(x-3)
Step-by-step explanation:
m=slope and b=y-intercept (probably useful for later on in the school years)
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
Substituting in what we know
y--4 = 9/4(x-3)
y+4 = 9/4(x-3)
Answer:
By the looks of it the answer is A
