a study of nickels showed that the standard deviation of the weight of nickels is 300 milligrams. A coin counter manufacture wishes to find the 90% confidence interval for the average weight of a nickel. What is the minimum number of nickels he needs to weigh to obtain an average accurate to within 20 milligrams?
Using the z-distribution, a sample of 609 nickels has to be weighed.
What is a z-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]
The margin of error is:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.[tex]\sigma[/tex] is the standard deviation for the population.For this problem, the parameters are:
[tex]M = 20, \sigma = 300, z = 1.645[/tex]
We solve for n to find the sample size, then:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]20 = 1.645\frac{300}{\sqrt{n}}[/tex]
[tex]20\sqrt{n} = 1.645 \times 300[/tex]

On Sunday, a local hamburger shop sold a combined total of 320 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Sunday?
Answer:
80
Step-by-step explanation:
1) if the number of hamburgers is 'h', number of cheesburgers is 'c', then
2) the condition 'The number of cheeseburgers sold was three times the number of hamburgers' can be written as c=3h. Also
3) the condition 'combined total of 320' can be written as h+c=320, then
4) it is possible to make up the system of equations:
[tex]\left \{ {{c=3h} \atop {c+h=320}} \right. \ = > \ \left \{ {{c=240} \atop {h=80}} \right.[/tex]
5) finally, number of hamburgers is 80.
Last year, Kevin had 20,000 to invest. He invested some of it in an account that paid 6% simple interest per year, and he invested the rest in an account that paid 10% simple interest per year. After one year, he received a total of $1480 in interest. How much did he invest in each account?
$13,000 was invested at 6% whereas $7,000 was invested at 10% using simple interest approach
What is simple interest?
Simple interest is determined as the amount invested multiplied by the interest rate and the number of years that investment lasts.
I=PRT
I=interest
P=principal
R=rate of return
T=time
Let X be the amount invested at 6%
I at 6%=6%*X*1
I=0.06X
The amount invested at 10% is 20,000-X
total interest=0.06X+0.10*(20000-X)
total interest=1,480
1480=0.06X+0.10*(20000-X)
1480=0.06X+2000-0.10X
1480-2000=0.06X-0.10X
-520=-0.04X
X=-520/-0.04
X=13,000
13,000 was invested at 6%

The diameter of a pipe is normally distributed, with a mean of 0.8 inch and a variance of 0.0004. What is the probability that the diameter of a randomly selected pipe will exceed 0.84 inch? (You may need to use the standard normal distribution table. Round your answer to three decimal places.) . Hint: take the square root of the variance to find the standard deviation.
The probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977
What is probability?Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
How to determine the probability?The given parameters are:
Mean = 0.8
Variance = 0.0004
Calculate Standard deviation using
σ = √σ²
This gives
σ = √0.0004
Evaluate
σ = 0.2
Calculate the z-score at x = 0.84 using
z = (x - [tex]\bar x[/tex])/σ = √σ²
This gives
z = (0.84 - 0.8)/0.02
Evaluate
z = 2
The probability is then represented as:
P(x > 0.84) = P(z > 2)
Next, we look up the value of the z table of probabilities
From the z table of probabilities, we have:
P(x > 0.84) = 0.977
Hence, the probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977

The intensity at a distance of 14 feet is 18.29 ft
How to find the intensity of light?The intensity (I) of a light source is inversely proportional to the square of the distance (d) from the source.
Light intensity refers to the strength or amount of light produced by a specific lamp source
The light intensity is measured in terms of lumens per square foot or lumens per square meter.
Therefore,
I ∝ 1 / d²
Hence,
I = k / d²
where
I = intensity of lightd = distance form the sourceTherefore,
k = Id²
k = 16 × 16
