The true statement about the bank survey is (e) The bank does not need to use an inference procedure to determine the participant proportion

The population and the sample size are given as:

N = 60

This is so because the bank surveyed all her staff.

Since all the bank staffs participated in the survey, it means that the proportion of the study is 1 or 100%.

So, the bank do not need to determine the proportion that participates

Hence, the true statement is (e)

The side of a larger cube is equal to 12 ft meanwhile the side of a small cube is equal to 4 ft.

A cube is a 3D- form of a square and its volume is found in the formula:

V=s³, where: s is the length of each side of a cube.

If the small cube has a volume ([tex]V_s[/tex]) of 64 ft³, you can apply the formula V=s³ for finding its the length of its sides. Thus

[tex]V_s[/tex]=64 ft³

[tex]s_v^3[/tex]=64

[tex]s_v=\sqrt[3]{64}\\ \\ s_v=4 ft[/tex]

A larger cube has sides ([tex]s_l[/tex]) that are three times as long as the small cube. Therefore, [tex]s_l=3s_v[/tex]. If [tex]s_v[/tex]=4 ft, the [tex]s_l[/tex] will be:

When x = x + 3, the value of 2x³ + x² - x is 2x³ + 19x² + 59x + 66.

When x = 3, the value of 2x³ + x² - x is 60.

Step-by-step explanation:

x = x + 3 solution:

It is given that:
f(x) = 2x³ + x² - x

We are trying to find this when x = x+3. Substitute this value in for every x in the function.

f(x + 3) = 2(x + 3)³ + (x + 3)² - (x + 3)

Expand the first part.

f(x + 3) = 2(x + 3)(x + 3)(x + 3) + (x + 3)² - (x + 3)

Multiply pairs together.

f(x + 3) = 2(x + 3)(x² + 6x + 9) + (x + 3)² - (x + 3)

Multiply the remaining pairs together.

f(x + 3) = 2(x³ + 9x² + 27x + 27) + (x + 3)² - (x + 3)

Distribute the two inside the parenthesis.

f(x + 3) = 2x³ + 18x² + 54x + 54 + (x + 3)² - (x + 3)

Evaluate (x + 3)².

f(x + 3) = 2x³ + 18x² + 54x + 54 + (x² + 6x + 9) - (x + 3)

Remove all parenthesis and start simplifying.

f(x + 3) = 2x³ + 18x² + 54x + 54 + x² + 6x + 9 - x - 3

Combine all terms ending in x².

f(x + 3) = 2x³ + (18x² + x²) + 54x + 54 + 6x + 9 - x - 3

f(x + 3) = 2x³ + 19x² + 54x + 54 + 6x + 9 - x - 3

Combine all terms ending in x.

f(x + 3) = 2x³ + 19x² + (54x + 6x - x) + 54 + 9 - 3

f(x + 3) = 2x³ + 19x² + 59x + 54 + 9 - 3

Last, combine the final numbers to get:

f(x + 3) = 2x³ + 19x² + 59x + 60

x = 3 solution:

It is given that:
f(x) = 2x³ + x² - x

Substitute 3 in for every value of the function.

f(3) = 2(3)³ + (3)² - 3

Evaluate 3 cubed and then multiply it by 2.

f(3) = 2(27) + 3² - 3

f(3) = 54 + 3² - 3

Evalute 3 squared.

f(3) = 54 + 9 - 3

Add 54 and 9.

f(3) = 63 - 3

Subtract 3 from 63 to get:

f(3) = 60

yes and you also have $1.06 as a remainder.

The perimeter of the rectangle of length (x₂ - x₁) and width (y₂ - y₁) will be 2(x₂ - x₁) + 2(y₂ - y₁). Then the correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

The length of the rectangle will be (x₂ - x₁) and the width of the rectangle will be (y₂ - y₁).

Then the perimeter of the rectangle will be

Perimeter = 2(x₂ - x₁) + 2(y₂ - y₁)

Answer:

Step-by-step explanation:

Part A, the system of equation is, presented here as follows;

(1) 2·y = 3·x + 2

(2) y = 2·x² - 3·x + 2

Part B; The graph of the system of equation is attached

The reason for the above answers is as follows;

Part A

A system of equations are a given number of equations from which a common solution of the system can be found

A linear equation is an algebraic equation in which the maximum exponent of the variables is one and the graph of the equation is a straight line which is of the form y = m·x + c

A maximum value of the exponents of the variable quadratic equation is 2, and the general form of the quadratic equation is y = a·x² + b·x + c, where a, b, and c are real numbers

Therefore, the system of equation that can be created is as follows;

(1) 2·y = 3·x + 2

(2) y = 2·x² - 3·x + 2

Method for solving;

Divide equation (1) by 2, and equate both values of y to find the common solution as follows;

2·y/2 = (3·x + 2)/2 = 1.5·x + 1

∴ y = 1.5·x + 1

Equating both values of y gives;

y = 1.5·x + 1

y = 2·x² - 3·x + 2

Therefore;

1.5·x + 1 = 2·x² - 3·x + 2

2·x² - 3·x - 1.5·x + 2 - 1 = 0

2·x² - 4.5·x + 1 = 0

Using the quadratic formula, we get;

x = (4.5 ± √((-4.5)² - 4×2×1))/(2 × 2)

x = 2, or x = 0.25

From which we get;

y = 1.5 × 2 + 1 = 4, or y = 1.5 × 0.25 + 1 = 1.375

The points where the line graph and the quadratic graph intersect are;

(2, 4), and (0.25, 1.375)

Part 2

Answer:

[tex]\sf Area\:of\:a\:triangle=\dfrac12 \times base \times height[/tex]

Given:

Substitute the given values into the equation and solve for h:

[tex]\sf \implies 18 = \sf \dfrac12 \times 6 \times (h+1)[/tex]

[tex]\sf \implies 18 = \sf \dfrac62 (h+1)[/tex]

[tex]\sf \implies 18 =3(h+1)[/tex]

expand using distributive property of addition [tex]a(b+c)=ab+ac[/tex]:

[tex]\sf \implies 18=3h+3[/tex]

subtract 3 from both sides:

[tex]\sf \implies 3h=15[/tex]

divide both sides by 3:

[tex]\sf \implies h=5[/tex]

To verify:

Half of the base is 3 cm.

If h=5, then the height of the triangle is 6 cm.

Multiplying 3 by 6 is 18.

This matches the given area, so we can verify that h = 5.

Answer:

Below!

Given:

Formula:

[tex]\text{Area of triangle} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]

Substitute the measures into the formula:

[tex]:\implies 18 \ \text{cm}^{2} = \dfrac{1}{2} \times 6 \times \text{(h} + 1\text{)}[/tex]

SImplify the R.H.S:

[tex]:\implies18 \ \text{cm}^{2} = 3 \times \text{(h} + 1\text{)}[/tex]

Divide both sides by 3:

[tex]:\implies \dfrac{18}{3} = \dfrac{3 \times \text{(h} + 1\text{)}}{3}[/tex]

Simplify both sides:

[tex]:\implies 6 = \text{(h} + 1\text{)}[/tex]

Subtract 1 both sides:

[tex]:\implies 6 - 1 = \text{h} + 1- 1[/tex]

Simplify both sides:

[tex]:\implies 5= \text{h}[/tex]

Reviewing on how to verify our answer:

We can verify our answer by substituting the value of "h" in (h + 1) to determine the height of the triangle. Then we can substitute the height and the base in the "area of triangle" formula (1/2 x Base x Height).

Verifying our answer through mental math:

Thus, the value of "h" is verified through mental math.

It is B.
