Mathematics

Answer:

19 sides

Step-by-step explanation:

Sum of angles of n-side polygon = 180 *(n - 2)

180 *(n -2) = 3060

Divide both sides by 180

n- 2 = 3060/180

n - 2 = 17

n = 17+2

n = 19

Answer:

19 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 3060° , then

180° (n - 2) = 3060° ( divide both sides by 180° )

n - 2 = 17 ( add 2 to both sides )

n = 19

The polygon has 19 sides

Is the system of equations consistent and independent, consistent and dependent, or inconsistent?
kobusy [5.1K]
Answer: (x,y)=(-22/69 , 2/23)

Y=6x+2
3x+12y=6x+2
Simplify the expression

-6x+y=2
-3x+12y=2
Multiply both sides of the equation by

-6x+y=2
6x-24y=-4
eliminate at least one variable by adding the equation

-23y=-2
Divide both sides

y=2/23
Substitute the value of y

-6x +2/23 =2
Solve the equation

x=-22/69
The possible solution of the system is the ordered pair

(x,y)=(-22/69, 2/23)
Check the solution

2/23=3x(-22/69)+12x 2/23=6x(-22/69)+2
Simplify

2/23=2/23=2/23
The ordered pair is a solution

Solution
(x,y)=(-22/69 , 2/23)

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 402 gram setting. It is
Mars2501 [29]

Answer:

Kindly check explanation

Step-by-step explanation:

H0 : μ ≥ 402

H1 : μ < 402

Test statistic :

n = 23

Sample Mean, x = 400

Variance = 900

σ = sqrt(900) = 30

Test statistic = (x - μ) ÷ σ/sqrt(n)

Test statistic = (400 - 402) ÷ 30/sqrt(23)

Test statistic = - 2 / 6.2554324

Test statistic = - 0.3197221

Test statistic = - 0.3197

Critical value :

Using the Tcritical value calculator

Tcrit; α = 0.025, df = n - 1 = 23 - 1 = 22

Tcritical = 2.074

Reject Null : if Test statistic ≤ Tcritical (left tail test)

Since ;

Test statistic ≤ Tcritical ; We reject the Null
