Answer:
506
Step-by-step explanation:
:. t6 = 46 ... [ Given ]
tn = a+(n-1) d ... [ Formula ]
:. t6 = a+(6-1) d
:. 46 = a+5d ... [1]
Sn = n/2 [2a+(n-1)d] ... [ Formula ]
:. S11 = 11/2 [2a+(11-1) d]
:. S11 = 11/2 [2a+10d]
:. S11 = 11/2x2 [a+5d]
:. S11 = 11[46] ... [ From (1)]
:. S11 = 506
You cant solve y but you can form an equation in terms of y
which is y=7-2x
if you were given another equation that has the term y and x than you can solve it.also that is a simultaneous equation.
Hope this helps,dont forget to put this as the brainliest answer if it does to help me out too. xD
Answer: 0.70
Step-by-step explanation the same as decreased by 30%" would be (1.00 - 0.30)(original cost), or 0.70(original cost)
Since there are two events happening simultaneously (windy and no sun), we can apply the concept of conditional probability here.
P(A|B) = P(A∩B)/P(B)
where it means that given B is happening, the probability that A is happening as well is the ratio of the chance for A and B to happen simultaneously over the chance of B to happen.
For our case, this can be interpreted as
P(A|B): it is the probability that it is windy (A) GIVEN that there is no sun (B)
P(A∩B) : chance of wind and no sun
P(B) : chance that there is no sun tomorrow
The chance of P(A∩B) is already given as 20% or 0.20. Since there is 10% or 0.10 chance of sun, then chances of having no sun tomorrow is (1-0.10) = 0.90.
Thus, we have P(A|B) = 0.2/0.9 ≈ 0.22 or 22%.
So, answer is B: 22%<span>.</span>
