Answer:
x=5
Step-by-step explanation:
7x-17=18
7x=18+17
7x=35
x=35/7
x=5
Answer:
Let's say something costs 100 pounds. If the cost is increased by 10 percent then it goes to 110 pounds. 10 percent of 110 is 11 so 110-11 is 99 (less than earlier. There you go.
There is no asymptote
The Y-int is (0,-1)
Answer:
=NORM.INV(0.17,98,15)
Step-by-step explanation:
Consider X represents the IQs of sample participants.
Then X follows the Normal Distribution with mean 98 and standard deviation 15.
That is,

The probability value is 17th percentile (that is 0.17)
To find the value of X using Excel, the<em> Inverse Normal Distribution </em>is used.
The Excel function =NORM.INV(0.22,105,17) is used to find the IQs of sample participants.
y= -947/8
Just isolate the variables, even though this is a long, painstaking, agonizing process
