A: The height of the street sign is obtained by indirect measurement method as 15 feet.

B: The two proportions Betsy can use is 5/1.5 = x/4.5 and 5/.x = 1.5/4.5

C: Using both the proportions height of the street sign is obtained as 15 feet.

What is indirect measurement?

A mathematical technique called as an indirect measurement is used to discover unknown measures of items that are challenging to measure. A direct measurement is something that can easily be measured, like a toddler's height.

The height of Betsy is h = 5 feet.

The shadow of Betsy is h' = 1.5 feet.

The height of the street sign is H = x feet.

The height of the shadow of street sign is H' = 4.5 feet.

The two proportions are -

h/h' = H/H' and h/H = h'/H'

These two can be used to find the measurement of the street sign.

To find the height of the street sign use the method of indirect measurement -

h/h' = H/H'     h/H = h'/H'

Substitute the values in the given equation -

5/1.5 = x/4.5            5/x = 1.5/4.5  

1.5 × x = 5 × 4.5      5 × 4.5 = 1.5 × x

1.5x = 22.5              22.5 = 1.5x

Simplify the equation further -

x = 22.5/1.5             x = 22.5/1.5

x = 15                       x = 15

Therefore, the value of the x is obtained as 15 feet.

To factor the expression 4x² - 8x + 4 completely, we can use the factoring method.
The expression 4x² - 8x + 4 can be factored as (2x - 2)(2x - 2).

Explanation:
1. First, we look for common factors, but in this case, there are none.
2. Next, we try to factor the quadratic trinomial. We can do this by finding two numbers that multiply to give the product of the coefficient of x² (which is 4) and the constant term (which is 4) and add up to the coefficient of x (which is -8).
  - In this case, the product of 4 and 4 is 16, and the sum of -4 and -4 is -8.
3. We rewrite the expression as 4x² - 4x - 4x + 4.
4. Now, we group the terms and factor by grouping:
  - Factor out 4x from the first two terms: 4x(x - 1).
  - Factor out -4 from the last two terms: -4(x - 1).
  - We can see that both terms have a common factor of (x - 1).
5. Factoring out (x - 1) from both terms, we get:
  - (x - 1)(4x - 4).
6. Finally, we can simplify further by factoring out 4 from the second term:
  - (x - 1)(4(x - 1)).
7. Combining like terms, we have:
  - (x - 1)(4x - 4) = (2x - 2)(2x - 2).

So, the expression 4x² - 8x + 4 can be factored completely as (2x - 2)(2x - 2).

a) The sum of m(arc AD) and m(arc BC) is 140°

b) The measurement of ∠ACD is 30°

The six trigonometric functions of an angle in a right-angled triangle are connected by a set of fundamental identities known as the "Circle identities" in trigonometry.

a) We know the circle identities;

In a circle an angle at center (O) always double the angle at its circumference.

then, ∠BOC = 2∠BAC = 2×40° = 80°

it also known as m(arc BC) = 80°

Similarly, for ΔAPB the sum of all angles are 180°

∠ABP + ∠APB + ∠BAP = 180°

∠ABP + 110° + 40° = 180°

∠ABP = 30°

Center angle always double the angle at its circumference,

then, ∠AOD = 2∠ABD = 2×30° = 60°

it also known as m(arc AD) = 60°

Therefore, the sum of m(arc AD) and m(arc BC) is,

m(arc AD) + m(arc BC) = 60° + 80° = 140°

b) Also we know that the angles on the same segment (AD) are always equal:

So, ∠ABD = ∠ACD = 30°

Because the segment AD is same for two angles.

After 10 days, the expected number of shoppers at the shopping mall is 163.

It is given that the number of shoppers increases daily by 5% from the number of shoppers the previous day.

As we can see that the increase in the number of shoppers is going to change every day, and the above case is compounded daily.

The formula of compound increase is

Amount = Base X (1 + r/n)ⁿˣ

where,

Base = original amount

r = rate of change

n = no. of times the change occurs in the time period

A 11.544 acre-feet of this ice field will melt from the beginning of day 1 (t = 0) to the beginning of day 4 (t = 3). So, correct option is C.

To solve the problem, we need to integrate the given rate of melting with respect to time over the interval [0,3] to find the total amount of ice that melts during this time.

First, we can simplify the given rate of melting by using the identity: sin³(t) = (3sin(t) - sin(3t))/4

So, M(t) = 4 - (3sin(t) - sin(3t))/4 = 16/4 - 3sin(t)/4 + sin(3t)/4 = 4 - 0.75sin(t) + 0.25sin(3t)

Integrating this expression with respect to t over the interval [0,3], we get:

\(\int\limits^3_0\) M(t) dt = \(\int\limits^3_0\) (4 - 0.75sin(t) + 0.25sin(3t)) dt

= [4t + 0.75cos(t) - (1/3)cos(3t)]|[0,3]

= (12 + 0.75cos(3) - (1/3)cos(9)) - (0 + 0.75cos(0) - (1/3)cos(0))

Number of voters who in favor of fire department bond measures = 248 ( no. of success)

Sample proportion is calculated by following formula, \(\hat p = \frac{x}{n} \)

where, X -->the number of successes

\( \hat p = \frac{258}{1000}= 0.258\)

Now, confidence interval, CI = 95%

Level of significance = 1 - 0.95 = 0.05

Margin of error helps the which percentage points results will differ from the real population value. Formula for margin of error is written as \(E = z_{\frac{\alpha}{2}} \sqrt{ \frac{\hat p ( 1 - \hat p)}{n}}\), where

Using the normal distribution table, the value of z-score for 95% of confidence interval is 1.96. Substitute all known values in above formula, \(E = 1.96 \sqrt{ \frac{0.258 ( 1 - 0.258)}{1000}}\)

The roots of a function are the x-values of the x-intercepts.

Therefore, if (-3, 0) is an x-intercept, then -3 is a root.

The zeros of the function are the x-values when y = 0.

(-3, 0) means x = -3 when y = 0.

Therefore, -3 is a zero.

According to the factor theorem, if f(x) is a polynomial, and f(a) = 0, then (x – a)  is a factor of f(x).

Step-by-step explanation:

The statement "An estimator is consistent if as the sample size decreases, the value of the estimator approaches the value of the parameter estimated" is False.

Consistency is an important property of estimators in statistics. An estimator is consistent if its value approaches the true value of the parameter being estimated as the sample size increases.

In other words, if we repeatedly take samples from the population and compute the estimator, the values we obtain will be close to the true parameter value.

This is an essential characteristic of a good estimator, as it ensures that as more data is collected, the estimation error decreases.

However, as the sample size decreases, the value of the estimator is more likely to deviate from the true value of the parameter. The reason for this is that a small sample size may not be representative of the population, and as a result, the estimation error may increase.

As a consequence, the statement is false. In conclusion, consistency is a property that an estimator possesses when its value converges to the true value of the parameter as the sample size grows.

As the sample size decreases, the estimator may become less reliable, leading to an increase in the estimation error.

Step-by-step explanation:

Since we know the triangles are similar, we can simply set up ratios to find the length of side length 'x'.

\(\frac{15.75}{x} = \frac{9}{15}\)

Cross multiply:

\(236.25 = 9x\)

Divide both sides by '9' to solve for 'x':

\(\frac{236.25}{9} = \frac{9x}{9}\)

\(x = 26.25\)

Therefore, side length 'x' equals 26.25 in.
