Answer:
The number b is bigger than the number a by of a.
Step-by-step explanation:
1. If the number a is smaller than the number b by 1/5 of b, then
Thus,
2. Consider the expression
This gives you that the number b is bigger than the number a by of a.
Answer:
Probability that at least one of them suffers from arachnophobia is 0.5160.
Step-by-step explanation:
We are given that a 2005 survey found that 7% of teenagers (ages 13 to 17) suffer from an extreme fear of spiders (arachnophobia).
Also, At a summer camp there are 10 teenagers sleeping in each tent.
Firstly, the binomial probability is given by;
where, n = number of trials(teenagers) taken = 10
r = number of successes = at least one
p = probability of success and success in our question is % of
the teenagers suffering from arachnophobia, i.e. 7%.
Let X = Number of teenagers suffering from arachnophobia
So, X ~
So, probability that at least one of them suffers from arachnophobia
= P(X >= 1) = 1 - probability that none of them suffers from arachnophobia
= 1 - P(X = 0) = 1 -
= 1 - (1 * 1 * ) = 1 - 0.484 = 0.5160 .
Therefore, Probability that at least one of them suffers from arachnophobia is 0.5160 .
Answer:
Step-by-step explanation:
Use the following equation the find the slope:
Rise over run is the change in the y-axis over the change in the x-axis from one point to the other. This is also known as the "slope". Insert the known values:
Solve:
Simplify. Two negatives make a positive:
Simplify fraction by dividing top and bottom by 5:
The slope is 3.
