Answer:
Option B) -9 is correct
The evaluated given expression when x=-3 is 2x+x=-9
Step-by-step explanation:
Given expression is 2x+x
Now to evalute the given expression when x=-3 as below :
2x+x when x=-3
That is put x=-3 in the given expression we get
2x+x=2(-3)+(-3)
=-6-3
=-9 ( adding the like terms here )
Therefore 2x+x=-9
The evaluated given expression when x=-3 is 2x+x=-9
Option B) -9 is correct
Answer:
Step-by-step explanation:
The unit circle has a hypotenuse of 1.
Answer:
a: about 66%
b: 25 minutes (24 minutes, 8.25 seconds, but we round up)
Step-by-step explanation:
Part a:
We will find the z-score if the situation.
µ = 19, σ = 2.5
x = 20.
The z-score is: z = (20 - 19)/2.5 = 0.40
P(z < 0.40) = 0.6554, so about 66% of customers would receive that discount
Part b:
We want to find the z-score that corresponds to 0.980, (top 2%). Looking of the chart we have to estimate since the exact value of 0.9800 isn't on the chart. z = 2.05 gives us 0.9798, and z = 2.06 gives us 0.9803. 0.9800 is just about in between them, so we average 2.05 and 2.06 giving us 2.055. We need to find the x-value that gives us a z-score of 2.055
2.055 = (x - 19)/2.5
5.1375 = x - 19 (multiply both sides by 2.5)
24.1375 = x (add 19 to both sides)
24.1375 minutes is 24 minutes 8.25 seconds. Rounding down to 24 minutes would make a little more than 2% get the discount, we need no more than 2%, so rounding up to 25 minutes would satisfy this requirement
