The least number of significant digits we can trust in the solution is 2.
The relative approximate error (RAE) of 0.004% gives us an indication of the precision of the solution at the end of an iteration, but it does not directly indicate the number of significant digits that can be trusted in the solution.
In general, the number of significant digits that can be trusted in a solution depends on several factors, such as the accuracy of the initial guess, the choice of method for finding the root, and the behavior of the function being evaluated.
As a rough estimate, it is common to assume that the number of significant digits in the solution is equal to the number of significant digits in the RAE, minus one.
In this case, the RAE is 0.004%, which has three significant digits, so the least number of significant digits we can trust in the solution would be
three - 1 = 2 significant digits

In 14 days, Lin's sister will be paid $430 and will deposit it into her checking account. If there are no other transactions besides this deposit and the daily fee, will Lin continue to be charged $5.95 each day after this deposit is made? Explain or show your reasoning.
The equation, fine is $5*86 = 430so 430-430 = 0, Lin's account balance is much above zero (0), so she won't be charged $5.95 each day.
What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.
Lin's sister will be paid $430
here are no other transactions besides this deposit and the daily fee
since fine is $5*86 = 430
so 430-430 = 0
hence,
Lin's account balance is much above zero (0), so she won't be charged $5.95 each day. However, if her account balance were to drop below zero, she would be charged for any further daily deposits made.

The statement 'Based on her electric bills from last year, Mrs. smith expects she will be paying $75/month this year' is not an example of descriptive statistics.
What is Descriptive statistics:Descriptive statistics is a branch of statistics that are used to characterize the features of a sample by using quantitative techniques.
Descriptive statistics can help to provide simple descriptions of the observations by using measures of Central Tendency like mean, variance, median, charts, etc...
Data with one variable are described using univariate descriptive statistics. On the other hand, data with several variables are described using bivariate and multivariate descriptive statistics.
The two categories of descriptive statistics are Measures of central tendency and measures of dispersion, which are used to summarize the characteristics of grouped and ungrouped data.
Measures of central tendency are Mean, Median, and Mode, where Measures of Dispersion are Range, Variance, Standard Deviation, Mean Deviation, etc.
Here we have

Mr. Macdonald has 480 animals on his farm . 0.5 of the animals arecows 1/8 are goats The remainder of the Animals are chickens and ducks if 33 1/3% are chickens how many ducks are on the farm?
Answer:
120
Step-by-step explanation:
480 total
1/2 = 240 are cows
1/8 = 60 are goats
remaining = 480-240-60 = 180 are chickens & ducks
33.3333% of 180 = chickens =180/3 = 60 chickens
so ducks = 180-60 =120
Answer:
120
Step-by-step explanation:
given that out of 480 animals 0.5 of the animals are cows . So ,
no. of cows = 0.5*480 = 240
Again, we are given that 1/8 of the animals are goats , so the number of goats would be ,
no. of goats = 1/8*480 = 60
Total no. of goats and cows ,
= 240 + 60 = 300
No. of remaining animals= 480 -300 = 180
Now out of these 180 animals 33⅓ % animals are chickens and remaining are ducks.
Percentage of ducks = (100 - 33⅓ )% = 66.67%
So the number of ducks would be ,
180 * 66.67/100 = 120

During a single day at radio station WMZH, the probability that a particular song is played is 42%. What is the probability that this song will be played on at least 3 days out of 6 days? Round your answer to the nearest thousandth.
Answer:
0.543 or 54.3%
Step-by-step explanation:
This is an example of a binomial distribution, where the probability of success (playing the particular song) is 0.42, and the number of trials is 6.
To find the probability that the song will be played on at least 3 days out of 6, we need to calculate the probability of the song being played on 3, 4, 5, or 6 days.
Using a binomial probability calculator or formula, we can calculate these individual probabilities:
Probability of the song being played on 3 days out of 6: 0.308
Probability of the song being played on 4 days out of 6: 0.177
Probability of the song being played on 5 days out of 6: 0.052
Probability of the song being played on all 6 days: 0.006
To get the probability of the song being played on at least 3 days out of 6, we add these individual probabilities together:
0.308 + 0.177 + 0.052 + 0.006 = 0.543
Therefore, the probability that the song will be played on at least 3 days out of 6 is 0.543 or 54.3% (rounded to the nearest thousandth).

Richard can expect the population to be 4,100 people 4 years after he moved there.
How to calculate the functionTo model the population growth, we can use an exponential equation in the form y = a * b^x, where a is the starting population (3,650), b is the growth factor, and x is the number of years after Richard moved there.
To find the value of b, we can use the population growth between the first year (x = 1) and the second year (x = 2). Let's call the population at x = 2 as P.
P = a * b^2
P = 3,869
Substituting the values, we get:
3,869 = 3,650 * b^2
Dividing both sides by 3,650, we get:
b^2 = 1.06
Taking the square root of both sides, we get:
b = 1.03
So, the exponential equation that models the Clover Hills population is:
y = 3,650 * 1.03^x
To find the population 4 years after Richard moved there (x = 4), we can substitute x = 4 into the equation:
y = 3,650 * 1.03^4
y = 3,650 * 1.129
y = 4,123.738
Rounding to the nearest hundred people, we get:
y = 4,100 people

Wildlife conservationists want to estimate the deer population in a region. They place an identifying tag on 220 deer. Several months later, researchers investigate 8 samples of 50 deer and record how many have a tag. Based on these results, how many deer should they estimate live in the region?
The estimated deer population live in the region is calculated as:
N = (2 * 220 * 50) / x
Estimate Deer PopulationOne method to estimate the deer population is by using the Lincoln-Petersen index, which is calculated as:
N = (2 * tagged deer count * sample size) / (number of tagged deer in the sample).
Using the data you provided, the number of tagged deer in the 8 samples is the sum of all the tagged deer counted in each sample, let's call this sum "x". Then, the estimated deer population in the region is calculated as:
N = (2 * 220 * 50) / x
Since the actual value of x is unknown, we cannot calculate the exact population. But, this formula gives us a method to estimate the population based on the number of tagged deer found in future samples.

You pick a card at random. 1 2 3 4 What is P(1 or even)? Write your answer as a percentage.
The probability of drawing a 1 or an even number from the set {1, 2, 3, 4} is 75%.
There are four cards in the set {1, 2, 3, 4}, of which two are even (2 and 4) and one is odd (1). To find the probability of drawing a 1 or an even number, we can add the probabilities of each event occurring:
P(1 or even) = P(1) + P(even)
Since each card is equally likely to be drawn, each of these probabilities is equal to the number of cards that satisfy the condition divided by the total number of cards:
P(1) = 1/4 (there is one card with a 1)
P(even) = 2/4 = 1/2 (there are two cards with even numbers out of four)
Therefore,
P(1 or even) = P(1) + P(even)
= 1/4 + 1/2
= 3/4
To express the answer as a percentage, we can multiply by 100:
P(1 or even) = 3/4 * 100%

the probability of that there will be 2 defective items among them is 0.476 or 47.6%.
What is probability?
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1. Calculating the possibility of an event occurring is the focus of the math discipline of probability. Probability gauges the likelihood of an event occurring.
