Answer:
y = -12x - 77
Step-by-step explanation:
The standard form of the equation is expressed as y = mx+b
m is the slope
Given the coordinate (-7, 7) and (-6, -5).
m = -5-7/-6+7
m = -12/1
m = -12
Get the intercept b
Substitute m= -12 and (-7 7) into y = mx+b
7 = -12(-7) + b
7 = 84 + b
b = 7 - 84
b = -77
Get the required equation
y = mx+b
y = -12x +(-77)
y = -12x - 77
This gives the required equation
Answer:
486
Step-by-step explanation:
Hello!
To find the surface area of a cube we use the equation

S is the surface area
a is the side length
Put what we know into the equation

Solve
S = 6 * 81
S = 486
Hope this Helps!
Answer:
0.18431525 = 18.4%
Step-by-step explanation:
General Formula :
total trials Cn⋅p(success)^n⋅p(fail)^total−n
1198144* (.0218)^3 * (1-.0218)^191
Solution :
Given :
Sample mean, 
Sample size, n = 129
Sample standard deviation, s = 8.2
a. Since the population standard deviation is unknown, therefore, we use the t-distribution.
b. Now for 95% confidence level,
α = 0.05, α/2 = 0.025
From the t tables, T.INV.2T(α, degree of freedom), we find the t value as
t =T.INV.2T(0.05, 128) = 2.34
Taking the positive value of t, we get
Confidence interval is ,


(32.52, 35.8)
95% confidence interval is (32.52, 35.8)
So with
confidence of the population of the mean number of the pounds per person per week is between 32.52 pounds and 35.8 pounds.
c. About
of confidence intervals which contains the true population of mean number of the pounds of the trash that is generated per person per week and about
that doe not contain the true population of mean number of the pounds of trashes generated by per person per week.
