D = d + Vt,
d = 1.0 miles,
V = -70 miles per hour,(- because its coming towards you)
And about D
Imagine you're standing at the centre of the street. a car is coming towards you. You can easily see that car will be X miles away from you two times. When Driving towards you And When Driving away from you. So
we have two D. + 0.15 miles and -0.15 miles.
0.15= 1 - 70t
-0.15=1-70t
From here
t equals
either
0.85/70 hours which is 0.85/70*3600 second about 43.7 sec.
or
1.15/70 hours or 1.15*3600/70 about 59 sec.
As we know that the sum of two sides of a triangle is greater than the third side ...
Option A is correct because 4+5=9>8
Option B is correct because 9+12=21>15
Option C is correct because 12+5=17>13
Hope it helps.....
Answer: The p-value is 0.154.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis :
Alternate hypothesis :
Population mean = 20 hours
Sample mean = 18.5 hours
Sample standard deviation = 4.3 hours
Sample size n = 35
So, test statistic would be
So, the p value would be 0.154.
Hence, the p-value is 0.154.
Answer: x = 1/2, y = 4
Step-by-Step Explanation:
Lets solve it using Substitution Method :-
=> 2x + 3y = 13 (Eq. 1)
=> 4x - y = - 2 (Eq. 2)
From Eq. 2 :-
=> 4x - y = - 2
= - y = - 2 - 4x
=> y = 4x + 2 (Eq. 3)
Substitute value of ‘y’ in Eq. 1 :-
=> 2x + 3y = 13
= 2x + 3(4x + 2) = 13
= 2x + 12x + 6 = 13
= 14x = 13 - 6 = 7
=> x = 7/14 = 1/2
Substitute value of ‘x’ in Eq. 3 :-
=> y = 4x + 2
= y = 4(1/2) + 2
= y = 4/2 + 2
=> y = 2 + 2 = 4
Therefore; x = 1/2, y = 4
