Let us say that this number is n
Then we could say:
<em><u>n - 9</u></em>
Answer:
0.6 is the probability of success of a single trial of the experiment
Complete Problem Statement:
In a binomial experiment with 45 trials, the probability of more than 25 successes can be approximated by 
What is the probability of success of a single trial of this experiment?
Options:
Step-by-step explanation:
So to solve this, we need to use the binomial distribution. When using an approximation of a binomially distributed variable through normal distribution , we get:
=
now,

so,
by comparing with
, we get:
μ=np=27
=3.29
put np=27
we get:
=3.29
take square on both sides:
10.8241=27-27p
27p=27-10.8241
p=0.6
Which is the probability of success of a single trial of the experiment
Answer:
x=-11/12
Step-by-step explanation:
Given an equation for x
x -2/3(3x - 4) + 3x = 5/6
We are asked to find the value of x.
We use equation rules to solve
To get rid of denominator in fraction, let us multiply the whole equation by 6.
6x-4(3x-4) +18x = 5
Simplify:
-6x+18x+16 =5
12x = 5-16 = -11
x = -11/12
Answer:
she purchased 6 first class tickets and 2 normal tickets
Step-by-step explanation:
Answer:
160 jars
Step-by-step explanation:
To find how many jars were used, we just need to divide the amount of stuff by the amount of stuff a jar can hold.
400 (the amount of peanut number in pounds) / 2.5 (the amount of peanut butter each jar can hold) = 160.
So, 160 jars were used to package the 400 pounds of peanut butter.
