The problem would be, 10+6x=4-4x. Then solve the problem by adding or subtracting the lowest variable to the other side and figure out the rest, if you can.
Answer:
<u>16.58€</u> considering the most favorable exchange rate to be 1$=0.91€ and the least favorable exchange rate to be 1$=0.91€. The answer cannot be any of the given options as usually there doesn't this much fluctuation occur on a specific day in exchange rate.
Explanation:
By converting the given amount of dollars (US) into Euros in both, most and least, exchange rate on a given day, we can find the saving in Euro for Sandy.
Step-by-step explanation:
Let on a specific day, the most favorable exchange rate was 1$=0.91€ and the least favorable exchange rate was 1$=0.91€. So,
Sandy exchanged the money on the most favorable time and got following amount in Euros:
829.04 * 0.91
=754.43
If Sandy would exchanged the money on the least favorable time on same day then she would have got following amount in Euros:
829.04 * 0.89
=737.85
Hence,
Sandy have 16.58 more euros. As,
754.43-737.85
=16.58€
Answer:
Consider lining up all the blue marbles and placing one red marble in between them. Let that arrangement be fixed. The remaining red marbles will be 5 red marbles. Note that the arrangement will be:
x BR x BR x BR x BR x BR x BR x BR x B x
Note that this is the same even if our arrangement is
x B x RB x RB x RB x RB x RB x RB x RB x
Note that there are 9 spots, denoted by x, where we can put the 5 remaining red marbles. To find the number of ways of putting the remaining 5 red marbles to x, it is similar in finding the number of non-negative solution for the equation
which is given by
= 1287
Hence, there are 1287 ways of arranging 8 blue marbles and 12 red marbles without placing 2 blue marbles next to each other.
Answer:
Claim :The proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%.
n = 170
x = 56
We will use one sample proportion test
The proportion, p, of full-term babies born in their hospital that weigh more than 7 pounds is 36%.
Formula of test statistic =
=−0.8311
Now refer the p value from the z table
P-Value is .202987 (Calculated by online calculator)
Level of significance α = 0.05
Since p value < α
So we reject the null hypothesis .
Hence the claim is true
