To obtain a smaller margin of error, choose a smaller confidence level.

Margin of error is defined as the degree of the sampling errors in statistics. It can be calculated using the formula below.

MOE = z x (SD / √n)

where MOE = margin of error

z = found by using a z-score table

SD = sample standard deviation

n = sample size

Based on the formula, to reduce the margin of error, the z-score, z, must be small. In order to have a smaller value of z, the probability, p, should also be small. And to obtain a small probability, choose a smaller confidence level.

Hence, to reduce the margin of error, use a lower confidence level.

Two triangles are congruent if two angles and a non included side of one triangle are congruent to two angles and a non included side of another triangle.

The relationship between the triangles ΔAOI and ΔIEA is ΔAOI ≅ ΔIEA

Therefore; ∠IEA is congruent to ∠AOI, by Corresponding Parts of Congruent Triangles are Congruent, CPCTC

∠IEA ≅ ∠AOI

Therefore; ∠IEA = ∠AOI by the definition of congruency

(6·z + 8)° = (7·z - 12)°

7·z - 6·z = (8 + 12)° = 20°

z = 20°

∠AOI = (7·z - 12)°

Therefore;

∠AOI = (7 × 20 - 12)° = 128°

∠IEA = 128°

Similarly; AO ≅ EI by CPCTC

x = 20° ÷ 5 = 4°

x = 4°

∠EAI = 3·(4·x - 1)°

Answer:

£9.40

Step-by-step explanation:

Given variables:

Defined variables:

1 pound = 100 pence  ⇒  1 pence = 0.01 pounds

Therefore, the equation that models the given scenario is:

[tex]y = 0.01px +f[/tex]

Given:

Substitute the given information into the equation to create two equations:

[tex]\implies f+0.01(4)p=5.40[/tex]

[tex]\implies f+0.01(7)p=7.80[/tex]

Therefore:

[tex]\implies f+0.04p=5.40[/tex]

[tex]\implies f+0.07p=7.80[/tex]

Subtract the first equation from the second to eliminate f:

[tex]\implies 0.03p=2.40[/tex]

Solve for p:

[tex]\implies \dfrac{0.03p}{0.03}=\dfrac{2.40}{0.03}[/tex]

[tex]\implies p=80[/tex]

Substitute the found value of p into one of the equations and solve for f:

[tex]\implies f+0.04(80)=5.40[/tex]

[tex]\implies f+3.20=5.40[/tex]

[tex]\implies f=2.20[/tex]

Substitute the found values of p and f into the equation to create an equation for the cost of x miles:

Therefore, the cost of a 9-mile journey is £9.40.

Answer:

Step-by-step explanation:

To write a linear function for a given set of points, we can use the slope-intercept form of the equation, which has the form f(x) = mx + b. The coefficient m is the slope of the line and the constant b is the y-intercept, where the line crosses the y-axis.

To find the slope m of the line, we can use the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are any two points on the line. For example, we can use the points (-2, -6) and (-1, -2.5) to find the slope:

m = (y2 - y1) / (x2 - x1) = (-2.5 - (-6)) / (-1 - (-2)) = 3.5 / 1 = 3.5

Now that we know the slope, we can use any of the given points to find the y-intercept b. For example, we can use the point (0, 1):

f(x) = mx + b

1 = 3.5 * 0 + b

b = 1

Therefore, the linear function that passes through the given points is:
f(x) = 3.5x + 1

Note that we could also have used any of the other points to find the y-intercept, and we would have arrived at the same result.

The solution to the system of equation is x = -12 and y = 3.

System of equation can be solved using different method such as elimination method, graphical method and substitution method,

Therefore, let's solve the system of equation by using substitution method.

1 / 2 x + 6y = 12

y = x + 15

substitute the value of y in equation(i)

1 / 2 x + 6(x + 15) = 12

1 / 2 x + 6x + 90 = 12

6 1 / 2 x = 12 - 90

13 / 2 x  = - 78

cross multiply

13x = -78 × 2

13x = -156

divide both sides by 13

x = -156 / 13

x = - 12

Let's find the value of y.

y = -12 + 15

y = 3

Therefore,

x = -12

Exponential smoothing is a technique used to smooth out data to uncover trends and make predictions. When setting the weight (w) for exponential smoothing, a large w will result in a longer-term trend being captured by the smoothing. This is because a larger w will give more weight to the older data points, and thus the overall long-term tendency of the series will be more visible. Therefore, it is true that setting a large weight w in exponential smoothing will help to see the overall long-term tendency of the series.

Answer:

130 ft

Step-by-step explanation:

The distance across the canyon is 130 feet.

When Christian moved 100 feet from the tree on his side, the angle formed by the tree on his side and the tree on the other side was 70°. This means that the distance across the canyon is the length of the opposite side of the right triangle formed by Christian's position, the tree on his side, and the tree on the other side.

To find the length of the opposite side of the triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the hypotenuse is the distance across the canyon, and the other two sides are 100 feet and the length of the opposite side of the triangle.

We can write this as an equation: (distance across the canyon)^2 = (100 feet)^2 + (opposite side of the triangle)^2.

To solve for the distance across the canyon, we can take the square root of both sides of the equation: distance across the canyon = √((100 feet)^2 + (opposite side of the triangle)^2).

Since the length of the opposite side of the triangle is equal to the length of the adjacent side (100 feet) divided by the tangent of the angle formed by the tree on his side and the tree on the other side, we can substitute this value into the equation above: distance across the canyon = √((100 feet)^2 + (100 feet / tan 70°)^2).

To calculate the value of tan 70°, we can use a calculator or look up the value in a table of trigonometric functions. The value of tan 70° is approximately 1.73. We can substitute this value into the equation above to get: distance across the canyon = √((100 feet)^2 + (100 feet / 1.73)^2).

We can now use a calculator to evaluate this expression and find the distance across the canyon. When we do this, we get: distance across the canyon = √((100 feet)^2 + (100 feet / 1.73)^2) ≈ 130 feet.

Therefore, the distance across the canyon is approximately 130 feet.

Step-by-step explanation:

To find the value of K, we need to use the remainder theorem. The remainder theorem states that if a polynomial is divided by (x - a), where a is a number, the remainder of the division will be equal to the value of the polynomial when x is equal to a. In this case, the remainder of the division is 10, so we need to find the value of the polynomial when x is equal to 1.

To find this value, we need to plug 1 into the original polynomial and evaluate it. This gives us (- 5 * 1^3 + 4 * 1^2 – 3 * 1 + K) = (- 5 + 4 – 3 + K) = (- 4 + K). Since the remainder of the division is 10, we know that (- 4 + K) = 10. This means that K = 14.

Therefore, the value of K in the original polynomial is 14.

The value of K is 14.

If a polynomial function f(x) is divided by (x - c), the remainder R is given by: R = f(c)

According to the remainder theorem, if a polynomial f(x) is divided by (x - c), where c is a constant, the remainder is equal to f(c).

In this case, we know that the remainder is 10 when the expression is divided by (x - 1). So, we can substitute x = 1 into the expression and set it equal to 10 to find the value of K.

Substituting x = 1 into the expression, we get:

(-5 (1)³ + 4(1)² - 3(1) + k)= 0

-5 + 4 -3 + k = 0

k -4 = 0

k = 4

Hence the exponential function that gives the value of the book in t years after 2010 is of:

V(t) = 500(1.18)^t.

2017 is 7 years after 2010, hence the value is calculated as follows:

V(7) = 500 x (1.18)^7 = $1,592.74.

First we obtain the rate of change, dividing consecutive entries of the table, as follows:

b = 62.99/34.99 = 1.8.

Thus the function is defined as follows:

f(x) = a(1.8)^x.

When x = 3, f(x) = 34.99, hence the intercept a is calculated as follows:

34.99 = a(1.8)³

a = 34.99/(1.8)³

a = 6.

Then the function is:

f(x) = 6(1.8)^x.

Taking 2016 as the reference year, the initial value is of:

a = 80.

Then the growth rate is of:

b = 132/80.

b = 1.65.

Then the function for the amount in x years after 2016 is of:

f(x) = 80(1.65)^x.

2023 is 7 years after 2016, hence the estimate is given as follows:

f(7) = 80 x (1.65)^7 = 2664 people.
