Answer:
P(X = 4) = 0.1876
Step-by-step explanation:
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.
In this question:
We want P(X = 4). So
Answer:
B. The show technicians had trouble wiring the equipment.
Step-by-step explanation:
When the machine arrived <u>they had trouble wiring it</u>, so instead of going off to college that morning for an orientation, <u>I spent several days at the theater fixing my light/sound equipment</u>.
If it was easy, the technicians would have been able to handle it. But also, the author would not have spent several days fixing it were simple. It delayed his plans to going off to college by several days.
Answer:
In average, houses in the particular area use 119,6 therms of gas during the month of January.
Step-by-step explanation:
The μ formula is:
μ= ΣXi/N
ΣXi= is the sum of each xi. xi is each observation in the sample.
N= Total number of observations.
For this case:
ΣXi= 125+103+118+ 109+ 122+ 82+ 99+ 138+ 151+ 149
ΣXi= 1196
N= 10
μ= 1196/10
μ= 119,6
In average, houses in the particular area use 119,6 therms of gas during the month of January.
Standard form is written Ax + By = C where A, B, and C are all integers.
In other words, no fractions.
Also, the A or the coefficient of the x term must be positive.
The only thing we need to do is add 7x to both sides to get 7x + y = -1.
So 7x + y = -1 is our answer.
Answer:
The correct answer is $2,50
Step-by-step explanation:
