Answer:
the probability of exactly 4 out of next 7 individuals that the sociologists survey earning over $50000 is given by
= = 0.09724
Step-by-step explanation:
i) This problem is solved by using the Binomial Probability distribution as the sample size is less than 30.
ii) The sample size is 7
iii) It is given that the probability of an individual earning over $50000 is 30% or 0.3 and therefore the probability of an individual not earning over $50000 is ( 1 - 0.3) = 0.7
iv) Therefore the probability of exactly 4 out of next 7 individuals that the sociologists survey earning over $50000 is given by
= = 0.09724

The light's coverage area is given mathematically as i.e. Area=
Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.
The revolving beam of light covers the whole space i.e entirely 360°
I.e. it forms a circle-like region
Area of circle = { where r is the radius of circle}
Let's assume the distance traveled by light as "d"
as it forms a circular region, it forms a circle of radius "d"
Mathematical connection i.e. area of the region
⇒area of circular region= {where d is the radius of region}

Answer:
48 assistants
Step-by-step explanation:
If 1 executive has an average of 1.5 assistants, let x represent the number of assistants that are employed if there are 32 executives in the office.
Thus:
1.5 assistants to 1 executive = x assistants to 32 executives
1.5 : 1 = x : 32
Cross multiply
Therefore, 48 assistants were employed in the office.
