Step-by-step explanation:
The coefficients are 4, 5 and 7
There is no constant
The second one is right
Answer: The reason why is because the numbers you are multiplying are both less than 1 so it has to be less the factors
Answer:
0.956
Step-by-step explanation:
X is the random variable representing the number of successes in the experiment in question;
X is represented by a binomial distribution with 5 trials and 0.18 probability of success, X~B (5, 0.18);
The probability of r successes, P(X=r), is found using the formula shown in second pic;
Working is shown in the other pic.
Answer:
x=20
Step-by-step explanation:
Well we know the right angle is 90 so...
And we also know that all the angle of a triangle add up to 180°.
Knowing this you can subtract 40° and 90°, this gives you 50°...
Then you can substitute 20° for x and then it will be 2(20°)+10°
Simplify and get 40°+10°
This equals 50° degrees
You then add that all up and you get 180°, this mean the answer is correct!
Hope this helps!
