Answer:
x = 25
Step-by-step explanation:
(4x - 35) = 180 - 115
4x - 35 = 65
4x = 100
x = 25
Answer:
130.81
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where from the question:
x is the raw score = ?
μ is the population mean = 100
σ is the population standard deviation = 15
We are told in the question that:
Mensa is an international society that has one and only one qualification for membership: a score in the top 2% on an IQ test.
The top 2% means a score in the 98th percentile
The z score of the 98th percentile = 2.054
Hence:
2.054 = x - 100/15
Cross Multiply
2.054 × 15 = x - 100
30.81 = x - 100
x = 30.81 + 100
x = 130.81
The IQ score that one should have in order to be eligible for Mensa is the score of 130.81

Answer:
562 feet of paper
Step-by-step explanation:
multiply 113 by 3 and thats the amount of paper Tommy used to make three 6 inch sandwiches, then add 223. And thats the answer.
A= 15+z+ square root 17(z+15)/ z-2
z=2a^2/(a-1)^2 + 30a/(a-1)^2 - 15/(a-1)^2
