Answer:
(f - g)(-4) = 17
Step-by-step explanation:
To get (f - g)(x), you need to subtract f(x) with g(x).
f(x) = 2x² + 2
g(x) = -3x + 5
(f - g)(x) = (2x² + 2) - (-3x + 5)
(f - g)(x) = 2x² + 2 + 3x - 5
(f - g)(x) = 2x² + 3x - 3
Now, plug in -4 to find (f - g)(-4).
(f - g)(x) = 2x² + 3x - 3
(f - g)(-4) = 2(-4)² + 3(-4) - 3
(f - g)(-4) = 2(16) + 3(-4) - 3
(f - g)(4) = 32 - 12 - 3
(f - g)(-4) = 17
Answer:
xyz
Step-by-step explanation:
Answer:
2.64
Step-by-step explanation:
The z score is calculated as
z=(x-mean)/Sd
The mean of scores of statistics exam=μ=99
The standard deviation of scores of statistics exam=σ=11
Individual's score in statistics exam=x=128
z=128-99/11=29/11=2.64
Hence, the z score of individual score is 2.64.
If there is a solution, y=y so we can say:
1.5x-1=1 add 1 to both sides
1.5x=2 divide both sides by 1.5
x=2/1.5
x=4/3 (exact)
x=1 1/3 (exact)
x≈1.33 (to nearest hundredth of a unit)
