Answer:
(a)
and 
Step-by-step explanation:
Required
Which of a to d has no solution
(a)
and 
We have: 
Sole for m



Divide by 6

So, we have:
and 
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
I don’t see the picture if I see it I can help you tho
Answer:
Please check the explanation.
Step-by-step explanation:
We know the equation
y = kx
k = y/x
where k is the proportionality constant
so,
First ratio can be calculated as
Miles = 45
Hours = 3/4
The ratio = 45 / (3/4)
= (45 × 4) / 3
= 180/3
= 60
Thus, the proportionality constant = 60
Thus, the remaining ratios can be calculated as:
The Pair (135, Hours)
135/Hours = 60
Hours = 135 / 60
= 27/12
= 9/4
= 2.25
Thus, the pair is (135, 2.25)
The Pair (Miles, 3)
Miles/3 = 60
Miles = 60×3
= 180
The Pair (90, Hours)
90/Hours = 60
Hours = 90 / 60
= 3/2
= 1.5
Thus, the complete table:
Miles 45 135 180 90
Hours 3/4 9/4 3 3/2
Verification:
Miles / Hour = 45/(3/4) = 60
Miles / Hour = 135 / 2.25 = 60
Miles / Hour = 180 / 3 = 60
Miles / Hour = 90 / 1.5 = 60
Answer:
9.50/ per hour
Step-by-step explanation:
adding the 8.5 x 3 (M/W/F)
plus the 6 x 2 (T/TH)
= 37.5 hours
356.75 divided by 37.5 = 9.5
Hope this helps
Answer with Step-by-step explanation:
We are given that two independent tosses of a fair coin.
Sample space={HH,HT,TH,TT}
We have to find that A, B and C are pairwise independent.
According to question
A={HH,HT}
B={HH,TH}
C={TT,HH}
{HH}
={HH}
={HH}
P(E)=
Using the formula
Then, we get
Total number of cases=4
Number of favorable cases to event A=2

Number of favorable cases to event B=2
Number of favorable cases to event C=2


If the two events A and B are independent then








Therefore, A and B are independent

Therefore, B and C are independent

Therefore, A and C are independent.
Hence, A, B and C are pairwise independent.
