Answer:
7 ( b + 4 ) = 9
Step-by-step explanation:
Let the number be = b
It is given that the :
The number is added to 4.
And the value is equal to 9 when it is 7 times the sum of the number, b and 4.
Thus according to the question, the sentence can be translated in equation form as :
7 ( b + 4 ) = 9
Thus in other word, we can say that the addition of (b + 4) when it is multiplied for 7 times, we get the result as 9.
Basically, the higher the price an item is the more you will be taking off of it if it is 10 percent off. For example, at $50, 10 percent off is $5, but at $55, it’s $5.50. There is more to take away, making the final price less than the original. Hope that make sense!
Answer:
Step-by-step explanation:
Given that reading on thermometer is N (0,1)
7% of the thermometers are rejected because they have readings that are too low, but all other thermometers are acceptable
This implies that we have to find out the 7th percentile.
i.e. Z score = -1.475
Hence the temperature for cutoff is below -1.475 degrees.
the temperature reading corresponding to the given information.=-1.475 deg
