The percent change is 40%

Step-by-step explanation:

The percent change is given by the formula

Percent\ change=\frac{New\ value-Original\ value}{Original} * 100

Here

New value = 70

Original value = 50

Putting the values in the formula

Percent\ change=\frac{70-50}{50}*100\\=\frac{20}{50}*100\\=0.4*100\\=40\%

The percent change is 40%

nasty-shy [4]

Answer:

Step-by-step explanation:

Let X be the IQ

IQ is normally distributed with a mean of 100 and a standard deviation of 15.

a) the probability that this person has an IQ greater than 95

=P(X\geq 95)\\=P(Z\geq \frac{95-100}{15} \\=P(Z\geq -0.33)\\=0.1293+0.5\\=0.6293

=62.93%

b) the probability that this person has an IQ less than 125

=P(X\leq 125) =P(X\leq 1.67)\\=0.5-0.4525\\=0.0475

=4.75%

c) Sample size =500

P(X

No of people = 0.2486(500) =124.3

d) P(x>140)\\= P(Z>2.6)\\=0.5-0.4953\\=0.0047

No of persons = 0.0047(500) = 2.35
