Answer:
b ≤ -4
Step-by-step explanation:
4b−4≤−20
4b - 4 + 4 ≤ - 20 + 4
4b ≤ -16
Divide both sides by 4
b ≤ -4
Explanation:
For the purpose of filling in the table, the BINOMPDF function is more appropriate. The table is asking for p(x)--not p(n≤x), which is what the CDF function gives you.
If you want to use the binomcdf function, the lower and upper limits should probably be the same: 0,0 or 1,1 or 2,2 and so on up to 5,5.
The binomcdf function on my TI-84 calculator only has the upper limit, so I would need to subtract the previous value to find the table entry for p(x).
Area = Length x Height
Area = 5.4 x 5.4
Area = 29.16

4/9= 0.444 ==> never ending, repeating
1/5= 0.2 =====> terminating
19/50= 0.38 => terminating
5/8= 0.625 ==> terminating
All of the above are terminating decimals except for 4/9!!

For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a
f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1
the axis of symmetry is x=-1
