Answer:
It takes 1.68 hours to catch up to them.
Step-by-step explanation:
The speed of robber = 71 mph
The speed of police = 78 mph
The police start 10 minutes later
by that time robber would have travelled
10 minutes =0.166667 hours
then the distance = 11.8 mph
Let them meet at distance x from the bank.
time taken by police to reach x , time =
----------------------(1)
time taken by robber in the same time = 
---------------(2)
Equating (1) and (2)
71x =78x - 920.4
920.4 = 78x - 71x
920.4 = 7x
x = 131.48
The distance where they catch up with the robber from the bank is 131.48 miles
speed of police = 78 mph
distance = 131.48 miles
time they catch up = 
= 1.68 hours
Answer:
99.8 %
Step-by-step explanation:
μ = 75 and σ = 5
The information about 68-95-99.7 rule is:
μ ± 0,5σ 68.3 % of all values will be in the interval
[ μ - 0,5σ ; μ + 0,5σ ] [ 72.5 : 77,5 ]
μ ± 1σ 95 % of all values will be in the interval
[ μ - 1σ ; μ + 1σ ] [ 70 : 80 ]
And:
μ ± 1,5σ 99.7 % of all values will be in the interval
[ μ - 1.5σ ; μ + 1.5σ ] [ 67,5 : 82,5 ]
And still 85 is bigger than 82,5 we can conclude that approximately 99.8 % will be smaller than 85 and then "the relative frecuency of rates less than 85 is very high 99.8 %
The linear equation in its generic form is:
y-yo = m (x-xo)
In this case we have that the slope is:
m = 300
The ordered pair is:
(xo, yo) = (2, 1400)
Substituting we have:
y-1400 = -300 (x-2)
Rewriting:
y = -300x + 600 + 1400
y = -300x + 2000
Answer:
a linear function that models this scenario is:
y = -300x + 2000
The slope of the line is:
-300
The y-intercept of the line is:
2000
Y = 11.5x + 22
y = -13x + 218
when will their balance be the same.....ur basically just subbing in 1 y for the other and u get :
11.5x + 22 = -13x + 218....now we solve for x
11.5x + 13x = 218 - 22
24.5x = 196
x = 196 / 24.5
x = 8 <== they will be the same at 8 weeks
11.5(8) + 22 = 114
-13(8) + 218 = 114
and they will both have $ 114 at 8 weeks <===
