The probability that the person has an IQ greater than 120 is 0.2524 of 25.24%
<h3>What is probability?</h3>
It is a branch of mathematics that deals with the occurrence of a random event.
Given:
IQ is normally distributed with a mean of 100 and a standard deviation of 15.
probability that the person has an IQ greater than 120,
P(x >120)
= P(Z > 120-100/ 15)
= P(Z > 0.667)
P(x >120) = 1- P(Z < 0.667)
= 1-0.7476
= 0.2524
= 25.24%
Hence, the probability is 0.2524.

Answer:
1 hotdog is $3.5.
1 drink is $2.
Step-by-step explanation:
18.50= 3x+4y(times 5)
25.50=5x+4y(times -3)
92.5=15x+20x
-76.5=-15x+-12y
16=-8y
2=y
18.50=3x+4(2)
10.50=3x+8
10.50=3x
3.5=x
Answer:
Step-by-step explanation:

Answer: 6 inches
Step-by-step explanation:
From the question, we are informed that a map in Connecticut is drawn to a scale where 2 inches on the map represents 35 miles.
If Greenwich and stonington are 105 miles from each other, to calculate their distance on the map will be:
Since 2 inches represent 35 miles, then: 1 inch = 35miles/2 = 17.5 inches.
Since 1 inch = 17.5 inches;
105 inches will then be: 105inches/17.5 inches = 6 inches
Therefore, 6 inches represent 105 miles.
