To boost the level of trust in the forecasted values, a balancing point must be attained.

The two phrases confidence interval and precision are intended to provide an accurate estimate of an object's measurability. We can compromise on the confidence level if the precision rises, but if the confidence level rises, the precision of the anticipated value likewise deteriorates.

Therefore, a balance point between these two variables must be reached in order to improve our confidence in the numbers being forecasted without compromising an accurate evaluation of accuracy. ensuring that accuracy and confidence are both upheld.

The slope intercept form of equation of required line is

[tex]y = \frac{3}{2}x + \frac{1}{2}[/tex]

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

Slope of the line = 1.5

The line passes through (21, 32)

Equation of required line =

[tex]y - 32 = 1.5(x - 21)\\y - 32 = \frac{3}{2}(x - 21)\\2y - 64 = 3x - 63\\2y = 3x - 63 + 64\\2y = 3x + 1\\y = \frac{3}{2}x + \frac{1}{2}[/tex]

Putting x = 1 on the line,

[tex]\frac{3}{2} \times 1 + \frac{1}{2}\\[/tex]

[tex]\frac{3 + 1}{2}\\\\\frac{4}{2}\\\\2[/tex]

(1, 2) is coordinate of another point on the line

Answer: B

Step-by-step explanation:

100/9

11.1

11 1/9

Using Simple Interest formula ,

The rate percent on amount of Rs.300 is 5.5 .

At same rate, R = 5.5 the principle 800 will be Rs1120 in next 7 years .

In first case we have given that ,

principle = Rs.350

time = 4 years

Amount = Rs 1120

simple interest = 1120-350 = Rs.770

let rate of interest be R% .

Using the formul of simple interest

S.I = P×R×t /100

=> 770 = 350×4×R/100

=> R = 5.5 %

In Second case , rate of interest is same as in first case. So,

Amount = Rs. 1120

Principle = Rs. 800

rate of interest (R)= 5.5

Again simple interest formula Used:

Simple Interest = (P × R × T)/100

Simple interest = 1120 - 800 = Rs. 320

Simple Interest = (P × R × T)/100

⇒ 320 = 800×5.5 ×T/100

=> T = 7.27 ~ 7

∴ In the given principle Rs 800 with same rate of interest will be 1120 in 7 next years .

The cost of a box of pasta is $2. 64, then what will you be charged for pasta this week is $1,125.

The average cost, or how much it generally costs to produce a unit, can be discovered using the cost function. The average cost function is defined as A(x)=C(x)x, where x > 0. The average cost per unit is calculated by dividing the total cost by the number of units produced.

Given,

Your ending inventories this week for pasta were 35, 41, 32, 19, and 47 boxes. You par value is 120 and a supplier comes each night.

Par level = [(120 - 35) + (120 - 41) + (120 - 32) + (120 - 19) + (120 - 47)]

Par level = [85 + 79 + 88 + 101 + 73]

Par level = 426 units.

Charges = par level × cost

Charges = 426 × 2.64

Charges = 1,124.64

Charges ≈ $1,125

She can see the horizon till 2.604 meters when the person is standing at a height of 5.76 meters above sea level.

Given that,

If a person can see d kilometers into the distance from her eye level, which is h meters above sea level, then d=3.57 √h. Let's say the person is standing at a height of 5.76 meters above sea level.

We have to find she can see the horizon, but how far.

The SI unit of length is the meter. In addition to meters, length can also be expressed in other units like centimeters, inches, feet, and yards.

So,

d=h

3.57 √h= 5.76 meters

Divide both sides by 3.57

√h= 5.76 meter/ 3.57

√h=1.614

30 cars of the delivery company use petrol.

According to the question,

We have the following information:

A delivery company has a total of 160 cars and vans.

The number of cars: the number of vans = 3:7

1/8 of the cars use electricity.

25% of the cars use diesel and rest use petrol.

Let's take the number of cars to be 3x and the number of vans to be 7x.

3x+7x = 160

10x = 160

x = 160/10

x = 16

Number of cars = 3*16

Number of cars = 48

Now, cars that use electricity:

1*48/8

6 cars

Cars that use diesel:

25*48/100

12 cars

Cars that use petrol:

Total number of cars-(number of cars that use electricity and diesel)

48-(6+12)

As given in the question,

Gross pay taken by Marquis is equal to $816

Items withheld from Marquis gross pay are as follow:

1. Federal tax = $92

2. Social security tax = 6.2% of gross pay

6.2% of 816

The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;

Pr(C & fewer than 3) = 0.1985

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Here, we are required to find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.

Let Pr(C) be the number of consumers who believe that cash will be obsolete in the next 20 years.

Therefore, since 39.7% believe so,

Pr(C) = 39.7/100 = 0.397

If 6 consumers are selected randomly, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years will be;

Probability of 2 out 6 to believe so or Probability of 1 out of 6 to believe so.

Pr(2/6) + Pr (1/6)

Therefore the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is;

Pr (fewer than 3) = (2/6) + (1/6)

Pr (fewer than 3) = 3/6

Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;

Pr(C) × Pr (fewer than 3)

i.e 0.397 × (3/6) = 0.1985

Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;

Pr(C & fewer than 3) = 0.1985

As given in the question,

Loan amount taken from the bank is equal to $35,000

Simple interest rate is 2%

Time period = 8 years

Total interest paid is equal to

= Loan amount × Interest rate × time period

= 35,000 × 2% × 8

= (35,000 × 2 × 8) / 100

Total amount to be paid

= Loan amount + Interest amount

= $35,000 + $ 5,600

= $ 40,600

Monthly payment done based on given interest and time period

= $40,600 / ( 8 × 12 )
