Using the normal distribution, it is found that 1851 people would have an IQ less than 115.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The proportion of IQ scores less than 115 is the <u>p-value of Z when X = 115</u>, hence:
Z = 1
Z = 1 has a p-value of 0.8413.
Out of 2200 people:
0.8413 x 2200 = 1851.

Answer:
7.6 in
Step-by-step explanation:
c = 2πr Divide each side by 2π
r = C/2π Insert values
r = 48/(2×3.14)
r = 48/6.28
r = 7.6 in
Answer: 6(17+14) or 186
Step-by-step explanation: I provide with you two answers since not sure what u mean .And the first answer is distributive it and the second answer is the sum.
Also 102 + 84 is an expression already so I don't know what your asking and if this help u are welcome !
Answer:
Step-by-step explanation:
Given inequality:
In order to represent the solution on the number line, we will first solve the given inequality.
We have
Subtracting both sides by 4.
Dividing both sides by -3.
[On dividing both sides by a negative number the sign of the inequality reverses.]
So, solution of this inequality will range from -3 to -∞
The number line is represented below.
