after collecting the historical data from a process of filling coca-cola bottles, it was found that the variance in the filling process is constant. however, clogs in the machine often affect the average volume. the historical standard deviation is 5 ml. in filling 250 ml bottles, a sample of 20 bottles found an average of volume of 246 ml. create a 95% confidence interval for the average volume of coca-cola in a bottle. can you conclude from your results that the manufacturer needs to adjust the equipment to meet the standard?

Answers

The manufacturer needs to adjust the equipment to meet the standard with the margin of error of 2.34.

Define the term margin of error?

The calculated number known as the margin of error is added to and removed from the mean value to get the resulting confidence interval. The confidence interval expands as the margin of error does.

Alpha value = 0.05Standard deviation = 5Sample size = 20Sample average = 246

Calculate the 95% confidence interval's margin of error based on the aforementioned data.

α = 0.05

n = 20

s = 5

The following is the formula to determine the margin of error:

E = T(n-1) ×s/√n

The t-distribution table is used to determine the value of tn-1 at 19 degrees of freedom.

Replace the values in the formula above.

E = 2.093 ×5/√20

Thus, its margin of error is 2.34 as a result.

The equation which has infinitely many solutions include the following: B. -6x + 35 = -6x + 35

What are infinitely many solutions?

In Mathematics, an equation is said to have an infinitely many solution when the left hand side and right hand side of the equation are the same or equal.

This ultimately implies that, an equation would have infinitely many solutions when both sides of the equal sign are the same, and both the slope and intercept for the two lines are the same.

In this scenario, we can reasonably and logically deduce that the following equations satisfy the condition for an equation which has infinitely many solutions:

-6x + 35 = -6x - 35 (False).

-6x + 35 = -6x + 35 (True).

6x + 35 = -6x + 35 (False).

6x + 35 = -6x - 35 (False).

The sum of the ages of pam,dion, and their three children, in years, is 5x - 99. where x is dion's age. pam is five years younger than dion. what is the usm of the ages of their children?

Answers

The sum of the ages of the children would be 3x - 94 years.

We have the total sum of the ages of pam ,dion and their children  

as 5x - 99

here , x is the age of Dion .

we see , pam is five years younger than Dion , so

age of Pam = x - 5

Now as the sum of all the ages = 5x - 99

therefore ,

Age of Dion + Age of Pan + Age of children = 5x - 99

x + x - 5 + Age of children = 5x - 99

2x - 5 + Age of children = 5x - 99

therefore ,

Age of children = 3x - 94

So  the age of their children would be 3x - 94 years

The general equation of a straight line is -

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

At [c] = 0 -

We have a directly proportional relation.

The general equation of a straight line is -

[y] = [m]x + [c]

At [c] = 0, y = mx

m = y/x

where [m] acts as a constant of proportionality.

So -

y = mx : represents direct proportionality between [y] and [x]. Its graph is a straight line.

a grocer stacks oranges in a pyramid-like stack whose rectangular base is 5 oranges by 8 oranges. each orange above the first level rests in a pocket formed by four oranges below. the stack is completed by a single row of oranges. how many oranges are in the stack?

Answers

The total number of oranges in the pyramidal stack is 78.

The oranges are stacked by the grocer in a pyramid like shape,

The base of the pyramid is rectangular with a size of 5 by 8 oranges,

So, total number of oranges in the base can be found as,

= 5 x 8

= 40 oranges.

One orange has four oranges below it. So, if there are 40 oranges in the base, the upper layer will have one row of oranges reduced from each side of the rectangular base.

So, every next level will have (L-1)(B-1) oranges, where L and B are the length and breadth of every preceding rectangle.

Hence, Oranges in level 1 = 4x8

Oranges in level 2 = 3x7

Oranges in level 3 = 2x6

Oranges in level 4 = 1x5

Hence, total oranges are, (40+21+12+5) oranges.

Total oranges stacked are 78 oranges.

The solution for x in the function when the function g(x) = 10 is 4

How to determine the solution for x in the function?

From the question, we have the following equation that can be used in our computation:

g(x)=x-4

To make the equation legible, we need to rewrite it

So, we have the following representation

g(x) = x - 4

Also from the question, we have

g(x) = 10

This means that we calculate x when g(x) = 10

Substitute the known values in the above equation, so, we have the following representation

10 = x - 4

So, we have the following equation

x - 4 = 10

Add 4 to both sides of the equation

So, we have the following representation

x - 4 + 4 = 10 + 4

Evaluate the equation

x = 14

What is test statistic?

A statistic used in statistical hypothesis testing is known as a test statistic. A test statistic, which can be thought of as a numerical summary of a data set that condenses the data into a single value that can be used to conduct the hypothesis test, is how a hypothesis test is typically expressed. A number derived from a statistical test of a hypothesis is the test statistic. It displays how closely your actual data match the distribution predicted by the statistical test's null hypothesis.

Here,

test statistic t is,

t = (x' - μ)/(σ/√n)

x'=8.12 hours

μ=8 hours

σ=0.72 hours

n=81 pilot

t=(8.12-8)/0.72/(√81)

=0.12/0.08

t=1.5

when a line intersects parallel lines, then the intersecting angles must be the same for each of the parallel lines.

so,

y = 139

and the angles y and x are supplementary (or a linear pair). that means together they have 180°.

that is simply because the sum of all angles around a single point on one side of a line must be 180° (because the line is like the diameter of a circle with the "rotation point" being the center, and one side of the line represents the half-circle).
