The minimum sample size is 11 needed to be 90% confident that the sample mean is within 1 point of the true population mean.

What is the mean?

Given:

Standard deviation, σ = 2points

Confidence level = 90%

Sample mean, ε = 1 point

At 90% confidence level

1 - α = 0.90

α = 1 -0.90

α = 0.10

α/2 = 0.05

Zα / 2 = Z₀.₀₅

= 1.645

To find n

n = (Zα / 2 )*(σ)²

= (1.645)² * (2)² / (1)²

= (2.706) * 4

= 10.8241

n = 11

Hence, the minimum sample size is 11 needed to be 90% confident that the sample mean is within 1 point of the true population mean.

In First Case Service fee is $0.95 , In Second Case The ticket price = $28 , In Third Case Ticket price = $45, Service Fee = $2.25

According to the given information

In First Case

We are given

The Ticket price is = $19

Service fee is 5% of ticket price

19 × 5% = 0.95

Service fee is $0.95

Total Cost including service fee is $19.95

In Second Case

We are given

Service fee = $1.4

The ticket price = 1.4 ÷ 5%

                          = $28

Total Cost including service fee is $29.4

In Third Case

Total Cost including service fee is $47.25

Ticket price = 47.25 ÷ ( 1 + 5% )

                    = $45

Service Fee = 45 × 5%

Given ▲ ABC and  ▲DEF are the examples of AAS congruence theorem.

According to the AAS, or Angle Angle Side congruence rule, two triangles are said to be congruent if two pairs of corresponding angles and the opposite or non-included sides are equal to one another.

The sides are not included between the angles but rather run in either direction of the angles, whereas the angles are sequential and corresponding in nature.

let's consider 2 triangles ▲ ABC ,  ▲DEF.

A at top B left C right . D at top E left F right side

∠B = ∠E

∠C = ∠F

AB = DE.

We can see that ∠B = E and ∠C = F if we superimpose the two triangles on top of one another. The lengths of the excluded sides, AB and DE, are also equal. As a result, we can state that ABC ≅ DEF.

Answer: 3.1, 1, -0.5, -2.85, -3.04

Step-by-step explanation:

Answer: 3.1, 1, -0.5, -2.85, -3.04

Step-by-step explanation:

The reason it is like this is because 3.1 is greater than the negative numbers and 1 so that would put it in first.

The second would be 1 because it is greater than all of the negative numbers.

The third would be -0.5 because it is greater than the other negative numbers.

The fourth would be -2.85 because it is greater than the last negative number.

So the fifth number would be -3.04 because it is the last number there is.

By solving the given equation x/7 - 6 = - x/6 + 5 we get x value = 462/13.

What is called the equation?

Given that :

     x/7 - 6 = - x/6 + 5

Multiply the denominators with numerator on both sides

                x / 7 - 6(7) = - x / 6 + 5(6)

                  x - 42 / 7 = - x + 30 / 6

Multiply both denominators with numerator on both sides

                  6 (x - 42) = 7 (- x + 30)

Multiply 6 and 7 inside the bracket

                   6x - 252 = - 7x + 210

Separate x terms and constant terms

                    6x + 7x = 210 + 252

                           13x = 462

                              x = 462 / 13

Therefore, x = 462 /13

The magnitude and direction of the resultant force are respectively; F = 44.954 N and θ = 36.47°.

We are given two forces as;

F₁ = 34 N

F₂ = 46 N

Angle between the two forces; θ =  42°

Now, the formula to find the resultant of the two forces is gotten by using the cosine rule as;

F = √[F₁² + F₂² + 2F₁F₂cos θ]

Where θ represents the angle between the two force vectors

Thus;

F = √[34² + 46² + 2(34 * 46 * cos 42]

F = 44.954 N

the direction will be;

θ = tan⁻¹(34/46)

Given the proportional relationship between the time  Whitney spends babysitting (in hours), x, and the amount of money she earns babysitting (in dollars), y, she needs to babysit for 2 hours to earn $12.

A proportional relationship refers to the relationship between two or more values with equal ratios.

Proportions are relative values or ratios, depicted in fractions, percentages, or decimals.

Equation, y = 6x

Where y = the amount of money Whitney earns babysitting (in dollars)

And x = the hours of babysitting

If y = $12, the number of hours that Whitney needs to babysit is 2 hours ($12/$6)

y = 6x

6x = y

x = y ÷ 6

x = 12 ÷ 6

x = 2

Check:

12 = 6x

12 = 6(2)

12 = 12

The missing side of the triangle is approximately 10.2 m. This solution assumes that the given sides form a right triangle.

To find the missing side of a triangle, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The formula for the Pythagorean theorem is:

a^2 + b^2 = c^2

where a and b are the lengths of the two sides of the triangle and c is the length of the hypotenuse.

The lengths of two sides of the triangle, 8.3 m and 5.9 m, and you need to find the length of the third side (the hypotenuse).

You can use the Pythagorean theorem to solve for the missing side as follows:

c^2 = a^2 + b^2

c^2 = 8.3^2 + 5.9^2

c = sqrt(8.3^2 + 5.9^2)

c = sqrt(69.29 + 34.81)

c = sqrt(104.1)

c = 10.2 m

Therefore, the missing side of the triangle is approximately 10.2 m.

This solution assumes that the given sides form a right triangle. If the triangle is not a right triangle, the Pythagorean theorem may not be applicable and a different method may be needed to find the missing side.

Answer:

Step-by-step explanation:

Use the slope formula to find the slope

Answer:

A

Step-by-step explanation:

16 / a = x (+ r)

16 is the dividend

a is the divisor

x is the quotient

(r is the remainder, if the division is an integer division)

the smaller the divisor, the larger the quotient, of course. and vice versa.

remember, a division is the calculation how often the divisor fits into the dividend.

therefore, the smaller the divisor, the more often it fits into the dividend.

the quotient must be greater than 4. so, 4 itself is not a valid quotient for this problem.

but let's start with it :

16 / 4 = 4.

so, a = 4 (B) is not a valid solution.

to make the quotient larger (than 4), a must be smaller than 4.

the only valid solution is

A a = 2

except for C all other answer options are larger than 4 making the quotient smaller than 4.

and C is negative, which would make the quotient negative and therefore smaller than 4.

so, A is the only remaining valid answer.

16/2 = 8

perfect. the quotient (8) is larger than 4.

Domain and range of a square root graph is  [0, ∞) and  [0, ∞) respectively.

Domain of a function:

The domain of a function is the set of input values (x) for which it produces an output value.

Range of a function:

The set of all output values of a function.

Like if we consider a function [tex]y = f(x)[/tex]

then input inside function that is x is know as domain of function

output of function that is y is known as range of function.

First we write square root function as y = [tex]\sqrt{x}[/tex]

So inside root negative numbers are not allowed so value of x should be positive numbers  means x>=0.

So domain of square root function [0, ∞).

Output of square root function is always positive so range of square root function is also [0,∞).

Given:

during the first leg of a backpacking trip, a group of hikers covered 10.4 miles in 3 hours and 1 minute.

he next day, the group hiked 8.6 miles in 3 hours and 47 minutes.

we are asked to find the group's average speed over the two days = ?

average speed = total distance / total time

total distance =  10.4 + 8.6 mi = 19 miles

total time =  ( 181 + 227 min ) = 408 min

hence average speed = ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr

The interval on which the graph is increasing and decreasing are ( -∞,3] and [3,∞) respectively.

There is no interval where the function is constant.

In order to solve this question we need to study the graph attached,

From the graph, we could see that the plotting of the graph is starting from the negative axes and we could observe an increasing slope in the function, and the increment stopped after reaching point B(3,0), we can also observe that the value of the y-axis increases with that of the x-axis.

The interval at B(0,3) must be wrote down as ( -∞,3]

Again we could see a sudden drop in the slope of the function of the graph as the slope of the graph this time starts decreasing and moves to infinity and again we could observe that the value of the x-axis starts decreasing with the decrease in the value of the y-axis.
