Answer:
Step-by-step explanation:
they want you to remember your algebra... :P
mulitply both sides by 5
5* = -7 * 5 this is fair.. b/c you have done the same thing to both sides of the equal sign... the equal sign remains true
now cancel the 5 s on the left
x = -35 and voila you got it
Answer:
B or 4
Step-by-step explanation:
I could be wrong as I'm very new to this math but I believe its 4
The center and shape of the distribution are 2.5 and symmetric. Then the correct option is B.
<h3>How to find that a given condition can be modeled by binomial distribution?</h3>Binomial distributions consist of n independent Bernoulli trials.
Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))
Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as
The probability that out of n trials, there'd be x successes is given by
Then the center and shape of the distribution will be 2.5.
