Step-by-step explanation:

Given Information:  

standard deviation = σ = 15 ft²

Confidence interval = 95%

Margin of error = 2.5 ft²

Required Information:  

Sample size = n = ?

Answer:

Sample size = n ≈ 139

Step-by-step explanation:  

The required number of observations can be found using ,

Me = z(σ/√n)

Where Me is the margin of error, z is the corresponding z-score of 95% confidence interval, σ is the standard deviation and n is the required sample size.

Rearrange the above equation to find the required number of sample size

√n = σz/Me

n = (σz/Me)²

For 95% confidence level, z-score = 1.96

n = (15*1.96/2.5)²

n = 138.29

since the sample size can't be in fraction so,

n ≈ 139

Therefore, a sample size of 139 would be needed.

The function [tex]k(x) = 2x^2[/tex] is which the average rate of change over the interval 1 < x < 5 greater than the average rate of change of g(x).

Given data:

The function is represented as [tex]g(x)=1.8x^2[/tex].

Now, the average rate of change of the function is S.

The value of [tex]S=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}[/tex].

The interval of the function is from 1 < x < 5.

So, for g(x), [tex]S=\frac{f(5)-f(1)}{5-1}[/tex].

The value of S = 10.8

For the function [tex]k(x) = 2x^2[/tex], the rate of change is:

[tex]S=\frac{k(5)-k(1)}{4}[/tex]

[tex]S=\frac{50-2}{4}[/tex]

So, the value of S = 12 and is greater than 10.8

Hence, the function is [tex]k(x) = 2x^2[/tex].

Answer:

30 fruits

Step-by-step explanation:

Let

x ----> number of plums on the plate

y ----> number of apples on the plate

we know that

The ratio of the number of plums to the number of apples was 3:2

so

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

[tex]x=1.5y[/tex] ----> equation A

After Ed took 6 plums from the plate, the number of plums remaining on the plate became the same as the number of apples

so

[tex]x-6=y[/tex] ----> equation B

substitute equation A in equation B

[tex]1.5y-6=y[/tex]

solve for y

[tex]1.5y-y=6\\0.5y=6\\y=12[/tex]

Find the value of x

Answer:

2 tan theta & sin2theta/cos^2theta

Step-by-step explanation:

Final answer:

The simplified forms of the expression sec^2(theta) sin(2theta) are 2 tan(theta) and sec^2(theta) - 1. These correspond to answer choices (c) and (d) respectively, by utilizing trigonometric identities to simplify the expression.

Explanation:

To find the simplified forms of the expression sec^2(theta) sin(2theta), we can use trigonometric identities. The identity for sin(2theta) is 2sin(theta)cos(theta). Since sec(theta) is the reciprocal of cos(theta), we can write sec^2(theta) as 1/cos^2(theta).

Therefore, the expression becomes:

sec^2(theta) sin(2theta) = (1/cos^2(theta)) * (2sin(theta)cos(theta))

We can simplify this further by canceling one cos(theta) from the numerator and denominator, which yields:

2sin(theta)/cos(theta)

Simplified, this is equal to 2 tan(theta), since tan(theta) = sin(theta)/cos(theta).

Using another trigonometric identity, sec^2(theta) = 1 + tan^2(theta), we can also express the original expression as:

sec^2(theta) - 1 which simplifies to tan^2(theta).

This means that the correct answers from the provided choices are (c) and (d).

Answer:

x=15.08 cm

y=7.54 cm

Step-by-step explanation:

We are given that

Volume of box=1715 cubic cm

Side length of base=x

l=b=x

Height of box=h=y

Volume of box=lbh=x^2y

[tex]1715=x^2y[/tex]

[tex]y=\frac{1715}{x^2}[/tex]

Surface area of box=Area of bottom+area of four faces=[tex]x^2+4xy[/tex]

[tex]S=x^2+4x(\frac{1715}{x^2}=x^2+\frac{6860}{x}[/tex]

Differentiate w.r.t x

[tex]S'(x)=2x-\frac{6860}{x^2}[/tex]

[tex]S'(x)=0[/tex]

[tex]2x-\frac{6860}{x^2}=0[/tex]

[tex]2x=\frac{6860}{x^2}[/tex]

[tex]x^3=\frac{6860}{2}=3430[/tex]

[tex]x=(3430)^{\frac{1}{3})=15.08[/tex]

Again differentiate w.r.t x

[tex]S''(x)=2+\frac{13720}{x^3}[/tex]

Substitute x=15.08

[tex]S''(x)=2+\frac{13720}{(15.08)^3}>0[/tex]

Hence, the surface area is minimum at x=15.08 cm

[tex]y=\frac{1715}{(15.08)^2}=7.54 cm[/tex]

The dimensions of the bin that will minimize the surface area are:

Base side (x): 7.5cm

Height (y): 36.13cm

Let's express the surface area and volume of the box in terms of x and y:

Surface area (A):

A = 2x^2 + 4xy

Volume (V)V = x^2y

We are given that the volume of the box must be 1715cm3:

1715cm3 = x^2y

Solving for y, we get:

y = 1715/x^2

Now, we want to minimize the surface area (A) subject to the constraint that the volume (V) is 1715cm3. We can use Lagrange multipliers to solve this optimization problem.

L(x, y, λ) = A - λ(V - 1715)

L(x, y, λ) = 2x^2 + 4xy - λ(x^2y - 1715)

Taking partial derivatives of L with respect to x, y, and λ, we get:

∂L/∂x = 4x + 4y - 2λxy = 0

∂L/∂y = 4x - λx^2 = 0

∂L/∂λ = -x^2y + 1715 = 0

Substituting V = x^2y into the third partial derivative, we get:

∂L/∂λ = -V + 1715 = 0

Solving these equations simultaneously, we get:

x = 7.5

y = 36.13

Answer:

It makes the solution of the equation easier

Step-by-step explanation:

Here we have the formula relating Celsius and Fahrenheit given as follows;

[tex]C = \frac{5\times (F - 32)}{9}[/tex]

From the above Celsius to Fahrenheit equation, we have that to solve for F we rearrange the formula as follows

[tex]C =\frac{5F}{9} - \frac{32\times 5}{9}[/tex]

Which is the same as

[tex]C =\frac{5F}{9} - 17\frac{7}{9}[/tex]

It is then seen that rearranging the equation between Celsius and Fahrenheit makes it easier to solve for either °C or °F.

Answer:

It’s easier to find the solution to a variable when that variable is by itself on one side of the equal sign. Rearranging formulas before substituting values for each variable makes calculations more straightforward. With this approach, we only need to perform operations such as multiplication, division, addition, and subtraction on one side of the equal sign, and we simplify instead of solving by using the properties of equality.

Equation     x² + 3x + 7 = 0

Let's solve this equation by two methods.

1) Completing the perfect square trinomial

                 x² + 3x      = -7

                 x² + 3x + (3/2)² = -7 + (3/2)²

                (x + 3/2)² = -7 + 9/4

                 (x + 3/2)² = -19/4

                 x + 3/2 = √-19/√4

                 x = -3/2 + √-19/2         It has imaginary solutions.

2.- Graph the equation

See the graph below.

In the graph we notice that the equation does not cross the x-axis so it does not have real solution.

Answer:

The total income after 29 days is $16,106,127.33

Step-by-step explanation:

This is a geometric progression with the first element being 0.03 and the ratio is 2. So if we want to know the total income after 29 days we can use the formula for the sum of elements in a series of that kind, this is given by:

sum(29 elements) = [(first element)*(1 - r^(29))]/(1 - r)

sum(29 elements) = [0.03*(1 - 2^(29))]/(-1)

sum(29 elements) =(0.03*(-536870911))/(-1)

sum(29 elements) = -16106127.33/(-1) = 16106127.33

The total income after 29 days is $16,106,127.33

Answer:

Yes

Step-by-step explanation:

For the equation to be equivalence then it must be

Reflexive, Symmetric and transitive

since |A|=|B|;  

Every element in A is in B then R is reflexive

If f(1) = g(1), then g(1) = f(1), so R is symmetric.

If f(1) = g(1) and g(1) = h(1), then f(1) = h(1), so R is transitive.

R is reflexive, symmetric, and transitive,

thus R is an equivalence relation.

Answer:

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

Step-by-step explanation:

To find a right angle we need to find the perpendicular line. The trick here is to do the flip of your slope and since there is no "that passes through the point (#, #) you're done after that. So the answer is

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

The dimensions of the tank that minimize the surface area are a square base of 24 ft × 24 ft and a height of 12 ft.

To minimize the surface area, we need to minimize the sum of the areas of the five sides of the tank. Let's denote the side length of the square base as x and the height of the tank as h.

Given that the volume V = 6912 ft³, and for a rectangular tank, the volume is V = base area × height = x² × h.

So, we have x² × h = 6912.

To minimize the surface area, we differentiate the surface area formula with respect to x, set it equal to zero, and solve for x.

The surface area A = x² + 4xh.

Differentiating A with respect to x, we get [tex]\frac{dA}{dx}[/tex] = 2x + 4h.

Setting [tex]\frac{dA}{dx}[/tex] = 0 gives us 2x + 4h = 0, so x = -2h.

Since x cannot be negative, we ignore this solution.

Now, using x² × h = 6912, we can solve for h:

h = [tex]\frac{6912}{x^{2} }[/tex]

Substituting x = -2h:

[tex]\[ h = \frac{6912}{(-2h)^2} = \frac{6912}{4h^2} = \frac{1728}{h^2} \][/tex]

Solving for h:

[tex]h^3 = \frac{1728}{h^2}\\h^5 = 1728\\h = \sqrt[5]{1728} = 12[/tex]

Now, substituting h = 12 back into x² × h = 6912:

[tex]x^2 \times 12 = 6912\\x^2 = \frac{6912}{12} = 576\\x = \sqrt{576} = 24[/tex]

There are 25 red flowers in the garden.

Step-by-step explanation:

In this problem we have a common issue where the number is repeated 3 times in questions. So I'll sove it using the ratio 5 reds to 10 yellows and the data that there are 75 yellows and red flowers in the garden.

Since we know that for every 5 red flowers in a garden there are 10 yellow ones, then the ratio of yellow flowers to red flowers is

ratio = red/yellow = 5/10 = 1/2

yellow = 2*red

Since there are 75 yellow and red flowers in the garden we have:

yellow + red = 75

2*red + red = 75

3*red = 75

red = 75/3 = 25

There are 25 red flowers in the garden.

Answer:

0.28142

Explanation

First change 0.792 into standard form

To evaluate the square root of 0.792 using tables, you would typically refer to a set of pre-calculated square root values in the form of a table. These tables were commonly used before calculators and computers became widely available.

To begin the evaluation process, you would follow these steps:
**Step 1: Locate the closest square values**
First locate the two perfect square values that surround 0.792. If you have a comprehensive table, you may find an exact value, but often you'll need to interpolate between two values.
**Step 2: Interpolation**
If 0.792 is not a value directly found in the table, you use interpolation. Let's assume that your table shows that the square root of 0.784 (which is \( 0.28²  \)) is 0.28, and the square root of 0.81 (which is \( 0.9²  \)) is 0.9. Your value, 0.792, lies between these two.
**Step 3: Estimation**
Since \( 0.28² \) is 0.784 and \( 0.9² \) is 0.81, 0.792 is closer to 0.784 than 0.81. You would then estimate it to be closer to 0.28 than 0.9.
**Step 4: Fine-tuning**
Now, find the difference between the square roots and the differences between the squares:
- The difference between 0.28 and 0.9 is 0.62.
- The difference between 0.784 and 0.81 is 0.026.
Next, find out where 0.792 falls between 0.784 and 0.81 in proportion to the difference between the square roots.
- The difference between 0.792 and 0.784 is 0.008.
- To find the proportion of 0.008 to the total difference 0.026, you divide 0.008 by 0.026 to get approximately 0.308.
- Now, multiply this proportion by the difference between the square roots to refine your estimate: 0.62 * 0.308 ≈ 0.191.
**Step 5: Calculate your estimate**
Add this value to the lower square root to get an approximation of the square root of 0.792:
0.28 + 0.191 ≈ 0.471.
**Final Answer**
The square root of 0.792 is approximately 0.471 using interpolation with table values.

Final answer:

The best estimate for (6.3 x 10⁻²) (9.9 x 10⁻³) in scientific notation is approximately 6.237 x 10⁻⁵.

Explanation:

To find the best estimate for (6.3 x 10⁻²) (9.9 x 10⁻³) written in scientific notation, you need to multiply the coefficients and add the exponents.

The product of 6.3x 10⁻² and 9.9 x 10⁻³ can be calculated as (6.3 x 9.9) x (10⁻² x 10⁻³). The coefficients multiply to give 62.37 (approximately), and the exponents add to give -5.

Therefore, the best estimate for (6.3 x 10⁻²) (9.9 x 10⁻³) in scientific notation is approximately 6.237 x 10⁻⁵.
