The amount that each person should pay is  $22.06   .

in the question ,

it is given that

total number of persons = 3 person + 1 = 4 persons

cost of the meal = $72.50

sales tax percent = 6.75%

tip percent = 15%

So , the amount of sales tax = 6.75% of cost = 0.0675 * 72.50 = $4.89

and , the amount of tip is = 15% of cost

= 0.15 * 72.50

= 10.87

So , the total amount payable is = cost + sales tax + tip

= 72.50 + 4.89 + 10.87

= 88.26

since the total number of persons is 4 ,

the amount per person is = 88.26/4 = 22.06

Therefore , The amount that each person should pay is  $22.06   .

Based on the given information, the researcher should not reject the null hypothesis if using an alpha level of 0.05.

In hypothesis testing, the null hypothesis is typically assumed to be true until there is sufficient evidence to reject it. To determine whether to reject the null hypothesis, researchers often compare the calculated F-value from an ANOVA test with the critical F-value. The critical F-value is based on the significance level (alpha) chosen for the test. In this case, the given F-value is 3.47 with degrees of freedom (3, 32), indicating that there are three groups and a total of 32 observations. To make a decision, the researcher needs to compare the calculated F-value to the critical F-value. If the calculated F-value is greater than the critical F-value, the null hypothesis is rejected. However, if the calculated F-value is less than or equal to the critical F-value, the null hypothesis is not rejected. Since the critical F-value corresponding to alpha = 0.05 is not provided in the question, we cannot determine whether the null hypothesis should be rejected.

The confidence interval for the given poll is; 51% to 57%

We are given that;

Sample proportion; p = 54% = 0.54

Margin of error; E = 3% = 0.03

Now, formula for confidence interval of proportions is;

p ± E

where;

p is sample proportion

E is margin of error

Thus;

CI = 0.54 ± 0.03

CI = (0.54 - 0.03), (0.54 + 0.03)

CI = (0.51, 0.57)

The absolute values of the three integer roots of the given polynomial are |a| = 0, |b| = 2011, and |c| = 2011.

The given polynomial is x³ - 2011xᵐ.

We are asked to find the absolute values of the three integer roots of this polynomial, denoted as a, b, and c.

To find the roots, we can set the polynomial equal to zero and solve for x:

x³ - 2011xᵐ = 0

Factoring out an x gives us:

x(x² - 2011xᵐ⁻¹) = 0

From this equation, we can see that one of the roots is x = 0.

Now let's focus on the second factor, x² - 2011xᵐ⁻¹ = 0.

This quadratic equation has two roots, which we can find using the quadratic formula:

x = (-b ± √(b² - 4ac))/(2a)

For this equation, a = 1, b = -2011, and c = 0. Substituting these values into the quadratic formula, we get:

x = (-(-2011) ± √((-2011)² - 4(1)(0)))/(2(1))
x = (2011 ± √(4044121))/(2)

Simplifying further, we have:

x = (2011 ± √(2011²))/(2)
x = (2011 ± 2011)/(2)

This gives us two possible values for x:

x = (2011 + 2011)/(2) = 2011
x = (2011 - 2011)/(2) = 0

Now we have three potential roots: x = 0, x = 2011, and x = 2011.

To find the absolute values of these roots, we take the absolute value of each:

|0| = 0
|2011| = 2011
|2011| = 2011

Therefore, the absolute values of the three integer roots of the given polynomial are |a| = 0, |b| = 2011, and |c| = 2011.

Answer:

\(\huge\boxed{\sf x = 83\°}\)

Step-by-step explanation:

So,

x + 53 + 44 = 180

x + 97 = 180

x = 180 - 97

\(\rule[225]{225}{2}\)

Answer:

x = 83

Step-by-step explanation:

You can apply the theory of euclidean triangle: all three measurements of a triangle sum up and equal to 180°.

Therefore, we sum three angles and set to 180°

\(\displaystyle{x^{\circ} + 44^{\circ} + 53^{\circ} = 180^{\circ}}\\\\\displaystyle{x^{\circ} + 97^{\circ} = 180^{\circ}}\)

Solve for x; subtract both sides by 97°:

\(\displaystyle{x^{\circ} + 97^{\circ}-97^{\circ}= 180^{\circ}-97^{\circ}}\\\\\displaystyle{x^{\circ} = 83^{\circ}}\)

Therefore, x = 83

Answer:

Step-by-step explanation:

a) sum of angle on the straight line TRW is 180.

Given <TRS = 2x+10

<SRW = x-10

<TRS+<SRW = 180

2x+10+x-10 = 180

3x = 180

x = 180/3

x = 60°

<TRV = 180°-(2x+10)

Substitute x = 60° into the expression

<TRV = 180-(2(60)+10)

<TRV = 180-(120+10)

<TRV = 180-130

<TRV = 50°

2) From the diagram attached <MHJ= <LHK (oppositely directed angle)

Given

<MHJ= x+15

<LHK = 2x-20

Substitute the given data into the formula to get x

x+15= 2x-20

x-2x = -15-20

-x = -35

x = 35°

Next is to get the measure of <MHJ

<MHJ = x+15

<MHJ = 35+15

<MHJ = 50°

We can determine the population in 1820 was 8.5753 using a linear equation.

A linear equation is one that has just a constant and a first order (linear) component, like y=mx+b, where m is the slope and b is the y-intercept.

When x and y are the variables, the aforementioned is sometimes referred to as a "linear equation of two variables."

dp/dt = \(1.37^{t}\)

Integrate both sides.

p[h] = ( \(1.37^{t}\))/In (1.37)   + c

1810 ⇒ t = 0

7.4 = 1/In (1.37) + C

C = 4.2235

p(H) = ( \(1.37^{t}\))/In (1.37) + 4.2235

P (1) =  \(1.37^{t}\)In (1.37) + 4.2235

In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.

Euro and Dollars:

The cost of the total fuel consumed can be determined by the conversion of the Euro into Dollars.

Given here,

Total distance = 5000 km

Average fuel consumption = 6 lit per 100 km = 0.06 lit / km

Average fuel cost = 1.063 EUR/lit

1 EUR  = 1.2 USD

So, Total fuel consumption,

⇒ 5000 km × 0.06 lit /km

⇒ 300 lit

Thus, Total fuel cost,

⇒ 300 lit × 1.063 EUR/lit

Step-by-step explanation:

The decay rate for the resale price of laser cutting tool will be -121000\(e^{-0.22t}\)

Let R is the resale value of a particular type of laser cutting tool after years

Where, R(t) = 550000\(e^{-0.22t}\)

Rate at which the resale value is changing will be dR/dt = 550000\(e^{-0.22t}\)(-0.22)= -121000\(e^{-0.22t}\)

Initial value of the laser cutting tool, at time ‘t’ =0 will be 550000\(e^{-0.22t}\)x0 = 550000

At time ‘t’ resale value is 550000 \(e^{-0.22t}\)

Therefore, the decay in resale price = 550000 - 550000 \(e^{-0.22t}\)

Therefore, the decay rate = (550000 - 550000 \(e^{-0.22t}\))/t = 550000(1-\(e^{-0.22t}\))/t

As we have dR/dt = R’ = -121000\(e^{-0.22t}\)

Therefore, R’(10) = -121000\(e^{-2.2}\) = -13407.18

Therefore, after 10 years the resale price will be -13407.18

R’(20) = -121000\(e^{-4.4}\)= -1485.55

Therefore, after 20 years the resale price will be -1485.55
