Answer:
6 packages.
Step-by-step explanation:
If they are $3 each, and you only have $18, divide 18 by 3, which gives you 6.
Answer:
I'm pretty sure its b>2
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
3>−b+5
Step 2: Flip the equation.
−b+5<3
Step 3: Subtract 5 from both sides.
−b+5−5<3−5
−b<−2
Step 4: Divide both sides by -1.
-b/-1 < -2/-1
Answer:
b>2
Answer:
answer = 3
Step-by-step explanation:
same slope and different y-intercept would make the two lines parallel. hope this helps <3
Answer:
x^2+y^2=9^2
Step-by-step explanation:
The standard equation of a circle is:
Where the center of a circle is (h,k) and r is the radius of the circle. In this case because a circle is equidistant from the center and we have a point where it passes through 9 that means that the radius is 9. However, since the standard equation states that we must write r in the form of 
this means that 
. Therefore by plugging in the values we have:
You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
