Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%

Answer:
Their slope is the same. Perpendicular
Step-by-step explanation:
3x + 4y = 12
4y=12-3x
y=-3/4x+3
6x + 8y = 48
8y=48-6x
y=-3/4+6
Answer:
7.5 miles per hour
Step-by-step explanation:
Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate
To find: speed in miles per hour
Solution:
Distance travelled by Kayla = 
mile
Time = 
hour
To find the speed in miles per hour, use the following formula:
Speed = Distance ÷ Time = 
miles per hour
Answer:
144 = arc DF
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
72 = 1/2 arc DF
Multiply by 2
2*72 = arc DF
144 = arc DF
Answer:
11
or 39.66 units.
Step-by-step explanation:
Use the distance formula!
