Answer: First : C, Variance: 84,000 , Standard deviation: 290
Step-by-step explanation:
i took the test
Multiply the √49 by √4 - this will give you √196 over 4
√196 = 14
therefore you have 14/4
divide each by 2 to simplify
this gives you 7/2 <-- your final answer
Answer:
The answer to your question is 2 hours
Step-by-step explanation:
Data
Juan speed = 4 mi/h
Cathy speed = 7 mi/h
t = x
Formula
speed = distance/time
Solve for distance
distance = speed x time
d = s x t
Distance travelled by Juan
d = 4t
Distance travelled by Juan in 1.5 h
d = 4(1.5)
d = 6 mi
total distance d = 6 + 4t
Distance travelled by Cathy
d = vt
d = 7t
Equal both equations
6 + 4t = 7t
Solve for t
6 = 7t - 4t
6 = 3t
6/3 = t
2 = t
Cathy wll catch up with Juan in 2 hours
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable. q = − 96.6 <-- (The 6 is repeated)
