Answer:
y=2 and x=1
Step-by-step explanation:
2y=7y-14+4
2y-7y=-14+4
-5y=-10/-5
y=2
4x=6-4+2x
4x-2x=6-4
2x=2/2
x=1
Answer:
gas = $0.23, electricity = $0.10
Step-by-step explanation:
Answer:
Probability of obtaining 6H and 4T = 0.2051
Step-by-step explanation:
Since for a fair coin,
Probability of obtaining Head = 0.5
p = 0.5
q = 1-p = 0.5
Probability of obtaining 6H and 4T = 10C6 (p)^6(q)^4 = 210*0.5^6*0.5^4
P(6H, 4T) = 0.2051
Answer: First option is correct.
Step-by-step explanation:
Since we have given that

We need to find the value of the function .
As we have given that x= - 1
so, we substitute the value of x in y :

So, the value of the function is -5.
Hence, First option is correct.
