Find examples of decimals in a news paper or magazine,on television,or on the internet.write a real word problem in which multiplies decimals
Decimals can be found in various sources including the internet, and they are used in everyday activities like shopping online. The word problem involves a book sale where a discount is given in decimal form.
Explanation:Decimals are usually found in various sources such as newspapers, magazines, television, and predominantly on the internet. For example, when we read about the latest international currency exchange rates or the percentage rates in the stock market, we encounter decimals.
Let's create a real-world problem involving decimals: Sam is browsing a popular online bookstore. He found a book he wanted to buy for $5.49. However, there is a pop-up stating that for today only, all books are discounted by 0.15 (or 15%). How much would the book cost after the discount?
To find the solution, subtract the discount from the original price in decimal form i.e., $5.49 * 0.15 = $0.82 (approx). Then subtract this amount from the original price, $5.49 - $0.82 = $4.67. So, Sam will pay $4.67 for the book after discount.

If the manager at first city bank surveys a sample of 100 customers to determine how many miles they live from the bank, is the mean travel distance for this sample considered a parameter or a statistic? explain.
The mean travel distance for the sample of 100 customers surveyed by the manager at First City Bank is considered a statistic.
Explanation:The mean travel distance for the sample of 100 customers surveyed by the manager at First City Bank is considered a statistic.
In statistics, a parameter is a numerical characteristic of the whole population that can be estimated by a statistic. Since the manager is surveying only a sample of customers, the mean travel distance calculated from this sample is a statistic, not a parameter.
For example, if the manager had surveyed all customers of First City Bank, then the mean travel distance calculated from that data would be a parameter.

what interest rate is needed for $9,500 to earn $900 in 19 months?
Answer:
The interest rate is 5.98%.
Step-by-step explanation:
To find : What interest rate is needed for $9,500 to earn $900 in 19 months?
Solution :
The formula of interest is given by,
[tex]I=P\times R\times T[/tex]
Where,
I is the interest amount I=$900
P is the principle P=$9500
T is the time T=19 months= [tex]\frac{19}{12}[/tex] year.
R is the interest rate
Substitute the value in the formula,
[tex]900=9500\times R\times \frac{19}{12}[/tex]
[tex]R=\frac{900\times 12}{9500\times 19}[/tex]
[tex]R=\frac{10800}{180500}[/tex]
[tex]R=0.0598[/tex]
The rate of interest in percentage is [tex]R=0.0598\times 100=5.98\%[/tex]
Therefore, The interest rate is 5.98%.
To earn $900 from $9,500 in 19 months, an annual interest rate of approximately 5.97% is needed.
To determine the interest rate needed for $9,500 to earn $900 in 19 months, we can use the simple interest formula:
Simple Interest Formula: SI = P × R × T
SI: Simple Interest ($900)
P: Principal ($9,500)
R: Annual Interest Rate (as a decimal)
T: Time (in years)
Convert 19 months into years: 19 months / 12 months/year = 1.5833 years.Substitute the values into the formula: $900 = $9,500 × R × 1.5833.Isolate R: R = $900 / ($9,500 × 1.5833).R = 0.0597, which is approximately 5.97% per year.Nia has number cards for 2,3,8,9 and 5.

A certain plant grows 1 1/6 inches every week. How long will it take the plant to grow 6 1/6 inches
Answer:
5 weeks 2 days
Step-by-step explanation:
A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches
1 week = 7 days
Therefore in 1 day the plant grows = [tex]\frac{\frac{7}{6}}{7}[/tex]
= [tex]\frac{1}{6}[/tex] inch
Now we have to calculate number of days in which the plant grows [tex]6\frac{1}{6}[/tex] inches ≈ [tex]\frac{37}{6}[/tex] inch
Number of days = [tex]\frac{\text{Total growth}}{\text{Growth in one day}}[/tex]
= [tex]\frac{37}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex]
= [tex]\frac{37}{6}[/tex] × 6
= 37 days ≈ 5 weeks and 2 days
It will take the plant 5 weeks 2 days to grow [tex]6\frac{1}{6}[/tex] inches.

In 2012, the average donation to the help way was $225 with a standard deviation of $45. in 2013, the average donation was $400 with a standard deviation of $60. in which year did the donations show a more dispersed distribution?
Final answer:
The donations in 2012 had a more dispersed distribution than in 2013, as indicated by a higher coefficient of variation of 20% compared to 15% in 2013.
Explanation:
To determine which year had a more dispersed contribution distribution, we examine the coefficient of variation (CV), which is calculated by dividing the standard deviation by the mean and then multiplying by 100 to express it as a percentage. A higher CV indicates a more dispersed distribution.
For 2012:
Mean = $225Standard Deviation = $45CV = ($45 / $225) x 100 = 20%For 2013:
Mean = $400Standard Deviation = $60CV = ($60 / $400) x 100 = 15%Comparing the coefficients of variation, we can conclude that the donations in 2012 had a more dispersed distribution than in 2013 since the CV in 2012 was higher.

When jumping, a flea rapidly extends its legs, reaching a takeoff speed of 1.0 m/s over a distance of 0.50 mm . part a what is the flea's acceleration as it extends its legs?
The flea's acceleration is 1,000 m/s².
Further explanationThe problem we overlook this time is about uniformly accelerated motion.
The list of variables to be considered is as follows.
[tex]\boxed{u \ or \ v_i = initial \ velocity}[/tex]
[tex]\boxed{u \ or \ v_t \ or \ v_i = terminal \ or \ final \ velocity}[/tex]
[tex]\boxed{a = acceleration \ (constant)}[/tex]
[tex]\boxed{d = distance \ travelled}[/tex]
Given that a take-off speed of 1.0 m/s over a distance of 0.50 mm.
The initial speed was zero from rest. It was asked about flea's acceleration when she extends her legs.
The formula we follow for this problem are as follows:
[tex]\boxed{ \ v^2 = u^2 + 2ad \ }[/tex]
a = acceleration (in m/s²)u = initial velocity = 0 m/sv = take off speed = 1.0 m/sd = distance travelled = 0.50 mmConverted 0.50 mm to meters: [tex]\boxed{0.50 \ mm = 0.50 \times 10^{-3} \ m = 5.0 \times 10^{-4} \ m}[/tex]
Steps:
We set the formula so that the acceleration becomes the subject.
[tex]\boxed{ \ v^2 = u^2 + 2ad \ }[/tex]
[tex]\boxed{ \ v^2 - u^2 = 2ad \ }[/tex]
[tex]\boxed{ \ 2ad = v^2 - u^2 \ }[/tex]
[tex]\boxed{ \ a = \frac{v^2 - u^2}{2d} \ }[/tex]
Substitute all data into equations.
[tex]\boxed{ \ a = \frac{(1.0)^2 - (0)^2}{2(5.0 \times 10^{-4})} \ }[/tex]
[tex]\boxed{ \ a = \frac{1}{10 \times 10^{-4}} \ }[/tex]
[tex]\boxed{ \ a = \frac{1}{1 \times 10^{-3}} \ }[/tex]
[tex]\boxed{ \ a = 1 \times 10^{3}\ = 1,000 \ m/s^2 \ }[/tex]
We get the flea's acceleration, i.e., 1,000 m/s².

The Flea acceleration as it extends its leg is [tex]\fbox{\begin\\\ 1000\ m/s^{2}\\\end{minispace}}[/tex].
Further explanation:
Given:
The takeoff speed of the flea is [tex]1.0\ \text{m/s}[/tex].
The distance cover by flea is [tex]0.50\ \text{m/s}[/tex].
To find:
The acceleration of the flea as it extended it legs.
Formula used:
The acceleration of the flea can be obtained by the given formula.
[tex]\fbox{\begin\\\ \math v^{2}=u^{2}+2as\\\end{minisapce}}[/tex] ....(1)
Here, [tex]v[/tex] is the final velocity of flea, [tex]u[/tex] is the initial velocity of flea, [tex]a[/tex] is the acceleration of the flea, [tex]s[/tex] is the distance cover by the flea.
Calculation:
The initial velocity of flea is [tex]0[/tex].
The final velocity of flea is [tex]1.0\text{m/s}[/tex].
The distance cover by flea is in millimeter.
Convert millimeter into meter as follows.
[tex]\fbox{\begin\\\ \begin{aligned}0.50 \text{ mm}&=\dfrac{0.50}{1000}\text{ m}\\&=0.0005\text{ m}\end{aligned}\\\end{minispace}}[/tex]

True or false: the standard deviation is the square root of the variance.
Answer:
True. The standard deviation is indeed the square root of the variance.
Explanation:
The standard deviation measures the dispersion or spread of data points around the mean in a dataset. It quantifies the average distance of data points from the mean. Mathematically, it's the square root of the variance, which is the average of the squared differences between each data point and the mean. By taking the square root, we return to the original scale of the data, making the standard deviation more interpretable. A higher standard deviation indicates greater variability, while a lower standard deviation suggests that the data points are closer to the mean, signifying less variability within the dataset.
