When it says 4x4 and 12x2 does that mean it’s squared or multiplied by those?
Answer:
y=4x+2
Step-by-step explanation:
To find the slope of a line, you would do y₂-y₁/x₂x₁
This would be 2-6/0-1...
So your answer would be -4/-1
After simplifying, your slope is 4.
To write this in slope-intercept form, that would be y=4x+2
Answer:
Step-by-step explanation:Sorry but I don't think any of those answers are correct its impossible to solve that
1. N added to six
N increased by six
2. w multiplied by four
w times four
3. Fifteen minus b
Fifteen decreased by b
4. Fourteen decreased by three times z
Fourteen minus three multiplied by z
Answer:
Step-by-step explanation:
Given the data table :
x : __ $2_ $14_ _$20 __ $100
P(x) : 0.40_ 0.20 _0.20 _0.20
The mean :
E(x) = Σ(x*p(x))
E(x) = (2*0.4) + (14*0.2) + (20*0.2) + (100*0.2)
E(x) = 27.6
The standard deviation :
SD(x) = sqrt(Σ(x² * p(x)) - E(x)²)
Σ(x² * p(x)) - E(x)² :
((2^2*0.4) + (14^2*0.2) + (20^2*0.2) + (100^2*0.2)) - 27.6^2
2120.8 - 761.76
= 1359.04
Sqrt(1359.04)
SD(x) = 36.865159
SD(x) = 36.87
