8 - 4(-x + 5)
As you already know, in order to find the equivalent expression to our already given one, we have to simplify it first :)
8 +4x - 20
**Remember that a negative times a negative is always a positive!!**
Add like terms.
4x + (8 - 20)
Simplify.
4x + (-12)
Get rid of parenthesis.
4x - 12
Look at our answer choices.
Our answer is a. 4x - 12
~Hope I helped!~
Answer:
step 1. y - y1 = m(x - x1). this is the equation given a point and a slope.
step 2. find the slope m. m = (y2 - y1)/(x2 - x1) = (4 - (-4))/(0 - 2) = 8/-2 = -4.
step 3. y - (-4) = -4(x - 2) ; y + 4 = -4x + 8.
step 4. y = -4x + 4.
Answer:
68 %
Step-by-step explanation:
Since we have our mean x = 250 and standard deviation σ = 20, we need to find how many standard deviations away the values 230 and 270 are.
Note x - σ = 250 - 20 = 230 and x + σ = 250 + 20 = 270
The values are one standard deviation away.
So, the values between 230 and 270 lie in the range x - σ to x + σ.
Since the batting averages are approximately normally distributed and for a normal distribution, 68 % of the values lie in the range x - σ to x + σ.
So, 68 % of Braves players fall between 230 and 270.
