The sample size required should be at least of size 30.
According to the Central limit theorem, if from an unknown population large samples of sizes n ≥ 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
\mu_{\hat p}=pμp^=p
The standard deviation of this sampling distribution of sample proportion is:
\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}σp^=np(1−p)
Here it is provided that manufactured items are selected from a large population in which 8% of the items are defective.
That is, the proportion of defective items is, p = 0.08.
For the sampling distribution of the sample proportion of defective items to be normally distributed the least sample size required is 30.
Thus, the sample size required should be at least of size 30.

Acids increase the concentration of hydronium ions in solution by donating hydrogen ions to water molecules. true false
The statement about Acids increasing the concentration of hydronium ions in solution is; True
What is the concentration of the solution?In pure water and in neutral solutions, we know that the Hydroxonium ions [H₃O⁺] and Hydroxyl Ions [OH⁻] are equal. Therefore, [H₃O⁺] = [OH⁻] = 1 * 10⁻⁷.
However, that concentration can be altered by the addition of an acid or abase. Thus, If an acid is added to pure water the concentration of hydronium ions in the solution will increase.

Give (in order) the correct coefficients to balance the following reaction: h2sncl6 + h2s → sns2 + hcl
Let a, b, c, and d be coefficients in the balanced reaction,
a H₂SnCl₆ + b H₂S → c SnS₂ + d HCl
Count the atoms on both sides and set the amounts equal to each other:
• H : 2a + 2b = d
• Sn : a = c
• Cl : 6a = d
• S : b = 2c
Suppose a = 1. Then
6a = d ⇒ d = 6
2a + 2b = d ⇒ b = (d - 2a)/2 = 2
b = 2c ⇒ c = b/2 = 1
So, the balanced reaction is
1 H₂SnCl₆ + 2 H₂S → 1 SnS₂ + 6 HCl
The correct coefficients in order to balance the reaction is 1, 2, 1, 6
How to determine the correct coefficients to balance the equation?To obtain the correct coefficients in order to balance the reaction, we shall obtain the balance equation. This is shown below:
H₂SnCl₆ + H₂S → SnS₂ + HCl
There are 2 atoms of S on the right side and 1 atom on the left side. It can be balanced by writing 2 before H₂S as shown below:
H₂SnCl₆ + 2H₂S → SnS₂ + HCl
There are 6 atoms of Cl on the left side and 1 atom on the right side. It can be balanced by writing 6 before HCl as shown below:
H₂SnCl₆ + 2H₂S → SnS₂ + 6HCl
Now, the equation is balanced. Thus, the correct coefficients needed to balance the reaction is 1, 2, 1, 6

Assume that louisa carried an average balance of $1,000 from her credit card purchases over the past year. the a.p.r. on her credit card for the past year was 19.99%. approximately how much interest would louisa have paid over the course of the year?
The approximate amount of interest that louisa would have paid over the course of the year is; $200.
How to Calculate Simple Interest?The amount of interest accrued in simple interest is given by the formula:
E = P*i*t
Where;
P is the balance.
i is the interest rate.
t is the time.
We are given;
Balance; P = $1,000, hence
APR of 19.99% and so i = 0.1999
time; t = 1 year.
Thus, the amount she will pay is:
E = 1000 * 0.1999 * 1
E = $199.9

This is from https://www.jiskha.com/questions/1578462/a-the-average-height-of-sunflowers-in-a-field-is-64-inches-with-a-standard-deviation-of
Answer:
a) The graph of a normal curve with a mean of 64" and a standard deviation of 3.5" is a bell-shaped curve with its
maximum value at x = 64.
Important points:
mean - 3 deviations: 64 - 3(3.5) = 64 - 10.5 = 53.5
mean - 2 deviations: 64 - 2(3.5) = 64 - 7 = 57
mean - 1 deviation: 64 - 3.5 = 60.5
mean: = 64
mean + 1 deviation: 64 + 3.5 = 67.5
mean + 2 deviations: 64 + 2(3.5) = 64 + 7 = 71
mean + 3 deviations: 64 + 3(3.5) = 64 + 10.5 = 74.5
b) If there are 3000 plants, approximately how many will be taller than 71"?
71" is 2 standard deviations above the mean. The region between two standard deviations below the mean and two standard deviations holds approximately 95% of the plants.
Therefore there will be approximately 5% of the plants divided equally between being taller than two standard
deviations above the mean and being shorter than two standard deviations below the mean. Thus, there will be
approximately 2.5% of the plants taller than 71": 0.025 x 3000 = 75 plants.

A laser beam is to be directed through a small hole in the center of a circle of radius feet. the origin of the beam is feet from the circle. at what angle of elevation should the beam be aimed to ensure that it goes through the hole?
Based on the radius of the circle and the origin of the beam, the angle of elevation to ensure that the beam goes through the hole is 15.95°.
What angle of velocity is needed for beam accuracy?The best operation to use would be the Tangent as the angle we are looking for is adjacent to the circle.
Solving gives:
tan (angle) = Radius of hole / Distance of beam
Angle = tan ⁻¹ (Radius of hole / Distance of beam)
