Answer:
first, we put them in order
78,[80],83,(85),86,[87],90
Q1 = 80
Q2 (median) = 85
Q3 = 87
Interquartile range (IQR) = Q3 - Q1 = 87 - 80 = 7 <==
Hope this helps!
I notice that both triangles have corresponding angles.
This means the triangles are similar.
Answer:
3x + 4.5x + 1 = 28
3.6 seconds
Step-by-step explanation:
Initial distance apart = 1 foot
Student A:
Walk rate = 3 ft per second
Student B:
1.5*3 = 4.5 ft per second
How long it will take to be a total of 28 feets apart
Distance = speed * time
Let time = x in seconds
Student A distance = 3x
Stident B distance = 4.5x
Initial distance = 1 foot
3x + 4.5x + 1 = 28
7.5x = 28 - 1
7.5x = 27
x = 27/ 7.5
x = 3.6 seconds
Start with the given equation. Subtract 32 from both sides. Multiply both sides by 5.
Divide both sides by
