Answer:

Y= 3X-7

Step-by-step explanation:

the equation of the line has the formular

Y-Y1= M (X-X1)

here, M= slope= 3

X1=2 Y1= -1

Y--1= 3(X-2)

Y+1= 3X-6

Y= 3X-6-1

Y= 3X-7

Answer:

y=3x-7

Step-by-step explanation:

1. Use The Slope Formula

y=mx+b

m=slope

b=y-intercept

2. Fill in the given values

y=3x+b

3. Use the given points to solve for b

-1=3*2+b

-1=6+b

-7=b

4. Final equation

y=3x-7

What is the product of (x+3) (3x -2)?

velikii [3]

Answer:

3x²+7x-6

Step-by-step explanation:

Original Equation;

(x+3)(3x-2)

Multiply the first term by the second term.

x(3x-2)+3(3x-2)

Multiply x by 3x and x by -2

3x²-2x+3(3x-2)

And then multiply 3 by 3x and 3 by -2

3x²-2x+9x-6

Group like terms

3x²-2x+9x-6

Simplify

3x²+7x-6

(x+3)(3x-2)

x(3x-2)+3(3x-2)

3x²-2x+9x-6

3x²+7x-6

Amanufacturer of potato chips would like to know whether its bag filling machine works correctly at the 433 gram setting. It is

ankoles [38]

Answer:

There is not enough evidence to support the claim that the bags are under filled.

Step-by-step explanation:

Given :

Population mean, μ = 433

Sample size, n = 26

xbar = 427

Variance, s² = 324 ; Standard deviation, s = √324 = 18

The hypothesis :

H0 : μ = 433

H0 : μ < 433

The test statistic :

(xbar - μ) ÷ (s/√(n))

(427 - 433) / (18 / √26)

-6 / 3.5300904

T = -1.70

The Pvalue :

df = 26-1 = 25 ; α = 0.05

Pvalue = 0.0508

Since Pvalue > α ; WE fail to reject the Null and conclude that there is not enough evidence to support the claim that the bags are underfilled
