Let's name the number 'n'. Now write an equation. 7*n +n^2 =12Now you can form a quadratic. n^2 +7n-12=0. Now you can use a myriad of methods to solve it. If you still need help, just message me.
Answer:
Yes
Step-by-step explanation:
Unit prices come from dividing the price, $6.99, by the amount of product, 6,
6.99 ÷ 6 = 1.165
Now, because you cannot have more than two digits in the cents part, you would round that up to $1.17 which is over $1.05 dollars per bottle.
Step 1) simplify the constants, so basically you are doing the 3-4 part and turning the equation in -8x-1>-1
Step 2) isolate the variable, first you need to add 1 to both sides to cancel it off then the equation is -8x>0. Next you divide both sides by -8, don't forget that when you multiply or divide by a negative you need to flip the sign which makes the equation x<0 because when you divide 0 by any number it is still 0
Hope this helped!
Answer: x<0
Answer:
-0.74
Step-by-step explanation:
The computation of Z is shown below:
According to the question, data provided in the question is as follows
P(Z > Z) = 0.23
Based on the above information, the calculation for Z is
Use the table of the standard normal distribution for z
By using this the Z value comes is -0.74
hence, in case of the standard normal distribution, the value of z is -0.74 and the same is to be considered
