The number of bracelets and earrings sold is 10 and 16.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 7 is an equation.
We have,
Bracelets = x
Earings = y
Cost of bracelets = $5.00
Cost of the earrings = $3.00
Now,
One day she sold 6 more earrings than bracelets and her sales totaled $98.
We can make two equations as,
y = x + 6 _____(1)
5x + 3y = 98 ______(2)
Substituting (1) in (2)
5x + 3(x + 6) = 98
5x + 3x + 18 = 98
8x = 98 - 18
8x = 80
x = 10
And,
y = 10 + 6
y = 16
Thus,
Bracelets = 10
Earings = 16

a package of aluminum foil contains 50. ft2 of foil, which weighs approximately 9.0 oz . what is the approximate thickness of the foil in millimeters?
The approximate thickness of the package of aluminum foil with given density and weight is equal to 0.002 millimeters.
1 ft = 30.48 cm
Area of aluminum foil = 50 ft²
= 50 × ( 30.48 )² cm²
= 46451.52 cm²
1 oz = 28.3495 grams
Weight of the aluminum = 9.0 oz
= 255.1455 grams
Density = 2.70 g/cm³
Density = weight / ( area × thickness )
⇒ Thickness = weight / ( area × density )
⇒Thickness = 255.1455 grams / ( 46451.52 cm² × 2.70 g/cm³ )
⇒Thickness = 0.00203

Find the mean absolute deviation for the set below 108, 53, 47, 22, 56, 62
Answer: The mean absolute deviation for the given data set is 19.
Step-by-step explanation:
The mean absolute deviation (MAD) is a measure of the variability of a set of data and is defined as the average of the absolute deviations of each data point from the mean. To find the MAD, we first need to find the mean of the data set, and then subtract each data point from the mean and take the absolute value of the result.
Here is the step-by-step process for finding the MAD for the given data set:
Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56
Subtract the mean from each data point:
108 - 56 = 52
53 - 56 = -3
47 - 56 = -9
22 - 56 = -34
56 - 56 = 0
62 - 56 = 6
Take the absolute value of each result:
|52| = 52
|-3| = 3
|-9| = 9
|-34| = 34
|0| = 0
|6| = 6
Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 19
So the mean absolute deviation for the given data set is 19.

Answer:

what information can you gather from the standard deviation, particularly as it pertains to the percentage of normal distribution?
The standard deviation of a data set provides information about the spread or dispersion of the data around the mean.
It helps to determine the percentage of normal distribution in the data. If the standard deviation is small, it indicates that the data is tightly clustered around the mean and a high percentage of the data falls within a few standard deviations of the mean. On the other hand, if the standard deviation is large, it suggests that the data is more spread out and a smaller percentage of the data falls within a few standard deviations of the mean.
In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. So, the standard deviation provides insight into the proportion of data points that are close to the mean, and therefore, the shape of the distribution.

a circle is divided into 4 sectors, the ratio of whose areas is what is the central angle of the largest sector in degrees?
With the ratio of 1 : 2 : 3 : 6, the central angle of the largest sector of the circle is 180°.
A circle is a two-dimensional shape consisting of all points in a plane that are at a given distance from the center. Equivalently, we can define a circle to be the curve traced out by a point that moves in a plane so that its distance from the center (a given point) is constant.
A sector is defined to be a part of a circle that is made of the arc of the circle along with its two radii. The shape of a sector of a circle is identical to the shape of a slice of pie or pizza.
We're given a ratio of 1 : 2 : 3 : 6 of all the 4 sectors of a circle. The largest sector in degrees is indicated by 6 out of 12 (12 being the sum of numbers in the ratio). We know that a circle is divided into 360°. Therefore, the central angle θ of the largest sector is:
θ = 6/12 x 360°
θ = 1/2 x 360°

What is reflection?A sort of symmetry known as reflective symmetry occurs when one half of an object mirrors the other half. It also goes by the name "mirror symmetry."
For instance, both the left and right sides of a human face are typically the same. Most butterflies have identical wings on their left and right sides.
The given points of the triangle are R(3,-4), S(3,-7), and T(8,-7).
The reflected points of the triangle will be:-
R(3,-4) = R'( 3, 4)
S(3,-7) = R'(3,7)
T(8,-7) = R(8, 7)
The translated points by 2 units down will be:-
R'( 3, 4) = R''( 3, 2)
R'(3,7) = S''( 3, 5)

what is the correct solution for the arithmetic expression (2 8)/2*9/3 using the order of operations employed by oracle 12c when solving equations?
The correct solution to the arithmetic expression (2 8)/2*9/3 using the order of operations as employed by Oracle 12c when solving equations is 4.
According to the Order of Operations, the first step is to evaluate expressions inside parentheses, then perform any multiplications or divisions, and finally perform any additions or subtractions. In this expression, the first step would be to evaluate the expression inside the parentheses: (28)/2. This evaluates to 14.
Next, the expression becomes 14 * 9/3. According to the Order of Operations, we need to perform the multiplication first, so 14 * 9 = 126. Finally, we perform the division: 126/3 = 42.
So, the correct solution to the expression (2 8)/2 * 9/3 is 42.
Order of operations is a set of rules used to determine the sequence in which arithmetic operations should be performed in a mathematical expression to obtain the correct result. The rules ensure that operations are performed in a consistent and predictable manner.

when constructing a confidence interval for a population proportion, we check that the sample size is less than 10% of the population size. a. why is it necessary to check this condition? b. what happens to the capture rate if this condition is violated?
(a) A reasonable guideline for ensuring that the sample size is small enough to give credible findings is to confirm that the sample size is less than 10% of the population size.
(b) The confidence interval may not correctly reflect the genuine population proportion, resulting in incorrect inferences and actions based on the findings.
(a)
This condition must be checked since the sample size must be much less than the population size to ensure that the sample is representative of the population. A high sample size may not fully represent the population, resulting in biased results.
(b)
If the sample size exceeds 10% of the population size, the "10% criterion" is violated. When this requirement is broken, the capture rate may rise, but the accuracy of the confidence interval may fall. As a result, the confidence interval may grow broader and less reliable in capturing the genuine population percentage.

How to find the scale factorThe scale factor is calculated by checking the proportions of the sides
Let the scale factor be k
10k = 14
k = 14/10
k = 1.4
solving for x
15 * k = 5x
15 * 1.4 = 5x
5x = 21
x = 21 / 5
x = 4.2
solving for y
y + 50 = 180
y = 180 - 50
y = 130
