The management of a large hardware store is interested in estimating the difference between the mean dollar amount of purchases made by customers who use the store’s credit card and the mean dollar amount of purchases made by customers who use a different credit card. a random sample of 74 customers who used the store’s credit card showed a mean purchase of $107 with a standard deviation of $12. a separate random sample of 58 customers who used a different credit card showed a mean purchase of $132 with a standard deviation of $9. technology was used to calculate that the correct number of degrees of freedom is 129.78.
The margin of error for a confidence interval of 98% that should be used to estimate the difference in the mean purchase is given by [tex]2.355\sqrt{\frac{12^2}{74} +\frac{9^2}{58} }[/tex]
What is a confidence interval?In Statistics, a confidence interval refers to a range of estimated values that defines the probability that a population parameter will lie within it.
This ultimately implies that, a confidence interval is an estimate of a range of estimated values (lower bound and an upper bound) that may contain a population parameter.
For a confidence interval of 98%, we have;
[tex]\alpha =1-0.98\\\\\alpha =0.02[/tex]
Therefore, the margin of error for a confidence interval of 98% that should be used by the management to estimate the difference in the mean purchase amount for these credit cards is given by:

Identify the relative molar amounts of the species in 0. 10 m kno3(aq). If the species are present in equal amounts, place them in the same box
The relative molar amounts of the given species are;
KnO₃ = 0 M
K⁺ = NO₃⁻ = 0.1 M.
H₃O⁺ = OH⁻ = 1 × 10⁻⁷ M
H₂O = 55.56 M
What is the Relative Molar Amount?
KnO₃ → K⁺ + NO₃⁻
In this dissociation, we see that 1 mole of KnO₃ produces 1 mol of K⁺ and 1 mol of NO₃⁻.
Thus, concentration of KnO₃ is 0 M while the concentration of K⁺ and NO₃⁻ are both 0.1 M.
Now, concentrations of H₃O⁺ and OH⁻ depends solely on the autoionization of water.
Thus, concentration of H₃O⁺ is equal to concentration of OH⁻ = 1 × 10⁻⁷ M. Finally, concentration of H₂O is calculated from it's (1 g/mL) and molar mass of H₂O is 18 g/mol. Thus, concentration = (1/18) * 1000= 55.56 M

The population of a town after t years is represented by the function (t)=7248(0. 983)t. What does the value 0. 983 represent in the situation?
Answer:
Exponential function: A function is in the form of; where a is the initial value and b is a factor which decides the exponential function increases or decreases.
If
0<b <1 , then the exponential function decreases.
b> 1, then the exponential function increases.
Given the function:
Since this function f(t) represents the population of a town after t years.
Also, it is an exponential function.
here, b = 0.983 < 1
So, the function f(t) would be decreased by a factor of 0.983.
Therefore, the value 0.983 represents, the population of the town is 0.983 times the population of the town in the previous year.

Based on past results and behaviour, supal company found that demand for its product varies inversely with the price of the product. If in 2002, the demand was 1600 units when the price was rs. 5 per unit, what will the demand (to the nearest unit) be in 2012 when the price is rs. 25 per unit?
The demand (to the nearest unit) in 2012 when the price is rs. 25 per unit is 320 units
Inverse variationLet the demand be represented as "d
Let the price of the product be represented as 'p"
If the product varies inversely with the price of the product, this is expressed as:
d = k/p
k is the variation constant
If in 2002, the demand was 1600 units when the price was rs. 5 per unit, then;
1600 = k/5
k = 5(1600)
k = 8000
In order to get the demand (to the nearest unit) in 2012 when the price is rs. 25 per unit;
d = k/p
d = 8000/25
d = 320

The combined area of the triangle cutouts is square inches. The area of the parallelogram is square inches. The altitude of the parallelogram rounded to two decimals is square inches
Based on the calculations, we have the following:
The area of the sheet of paper is 96 square inches.The combined area of the triangle cutouts is equal to 36 square inches.The area of the parallelogram is equal to 60 square inches.The altitude of the parallelogram is equal to 6.51 square inches.Given the following data:
Dimension of paper = 12-inch by 8-inch.How to calculate the paper's area.Mathematically, the area of the paper is given by this formula:
