The statements that best describe the bowling scores data are:

- The MAD best describes the variability (C)

- The IQR best describes the spread (D)

Based on the given data in the table, the following statements can be made:

- There are no outliers in the data set, as all the scores fall within a reasonable range.

- The mean can be calculated as:

Mean = [tex]\frac{121 + 159 + 146 + 132 + 149}{5}[/tex]

          = 141.4,

but it may not be the best measure of central tendency due to the small size of the data set and the presence of outliers in larger data sets.

- The MAD (Median Absolute Deviation) can be calculated as the median of the absolute deviations from the median, which are:

|121 - 146| = 25,

|159 - 146| = 13,

|146 - 146| = 0,

|132 - 146| = 14,

|149 - 146| = 3.

The median of these values is 13, so the MAD is 13.

This describes the variability of the data well, as it takes into account the distance of each score from the median.

- The IQR (Interquartile Range) can be calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data set. To do this, we need to first find the median of the lower half of the data set (Q1) and the median of the upper half of the data set (Q3). Ordering the data set from lowest to highest, we have:

               121, 132, 146, 149, 159.

Q1 is the median of the lower half, which is:

Median = [tex]\frac{121 + 132}{2}[/tex]  = 126.5.

Q3 is the median of the upper half, which is

Median = [tex]\frac{149 + 159}{2}[/tex] = 154.

The IQR is then:

IQR = Q3 - Q1

       = 154 - 126.5

       = 27.5.

This describes the spread of the data well, as it captures the middle 50% of the data set.

An equation, in slope-intercept form, for the line of best fit for the table  above is y = 0.05x + 0.7.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (1.3 - 1.1)/(4 - 8)

Slope (m) = -0.2/4

Slope (m) = 0.05

At data point (8, 1.1) and a slope of 0.05, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1.1 = 0.05(x - 8)  

y = 0.05x - 0.4 + 1.1

y = 0.05x + 0.7

Answer: The digit in the following number is the one that determines its precision is 1.

Step-by-step explanation:

Precision is the ability to consistently produce outcomes with a high degree of accuracy. In general, precision can be thought of as the opposite of randomness or imprecision. It is also important for creating and maintaining machines, such as those in manufacturing, and for ensuring that the parts involved in a process fit together exactly as they should.

Since this number is 34.81, the precision is determined by the value at the 2nd decimal place which is 1 since it determines the how the value is performing at the second decimal place after the first decimal place. Hope this helps!

In the given diagram, given that the shapes have the same area, the value of y is 3.

From the question, we are to determine the value of y in the given diagram.

From the given information,

The yellow shapes have the same area.

The area of the shape is

Area = 8 × (3y + 1)

Area = 24y + 8

For the second shape,

Area = (15 × (y + 5)) - (4 × (7y - 11))

Area = (15y + 75) - (28y - 44)

Area = 15y + 75 - 28y + 44

Area = 119 - 13y

Since the shapes have the same area, we can write that

24y + 8 = 119 - 13y

24y + 13y = 119 - 8

37y = 111

y = 111/37

After following the steps of quadratic equation described below,

We can prove,

⇒ x =  -b±√(-4ac+  b²)/2a

Given that;

The quadratic equation is,

ax²+bx+c = 0,

As a result, the following steps must be taken to obtain the quadratic formula from the equation:

ax²+bx+c = 0

Take subtraction of c both sides.

ax²+bx+c-c = 0-c

ax²+bx = -c

Substitute a for both sides of the equation.

ax²/a + bx/a = -c/a

x² + bx/a = -c/a

Complete the square by adding  (b/2a)² times a squared to each sides.

x² + bx/a +  (b/2a)² = -c/a +  (b/2a)²

Square the quantity  b/2a on the right side of the equation

x² + bx/a +  (b/2a)² =  -c/a +  b²/4a²

Find the lowest common denominator on the right side of the equation. 4a²

x² + bx/a +  (b/2a)² =  -4ac/4a² +  b²/4a²

Add the fractions on the right side of the equation together.

x² + bx/a +  (b/2a)² =  (-4ac+  b²)/4a²

Because, as shown in the question, the fraction on the right-hand side of the equation is to be added together rather than multiplied.

As demonstrated, the equation on the left should be expressed as a perfect square.

(x+b/2a)² =  (-4ac+  b²)/4a²

Add the square roots of both sides together.

√(x+b/2a)² = √ (-4ac+  b²)/4a²

(x+b/2a) =  √(-4ac+  b²)/2a

Take b/2a off both sides.

x+b/2a - b/2a =  -b/2a + √(-4ac+  b²)/2a

x =  -b/2a + √(-4ac+  b²)/2a

Add the fractions on the right side together.

x =  -b±√(-4ac+  b²)/2a

First find the diameter of the small pizza.

Area = π r²

We have the area 201 in².

Let's subsitute into the formaula to find diameter of the small pizza.

201 in² = (3.14)π²

Divide both sides by π.

64.013 = r²

√64.013 = √r

8 = r (approximately) diameter is 2 times the radius.

So if the diameter of the small pizza is 8 × 2 = 16.

And the diameter of the large pizza is 16 × 2 = 32

Area of large pizza = π r²

radius would be half the diameter or 16

Area = 3.14 × 16²

We need to arrange the numbers in order to find the median

22, 24, 24, 25, 28, 29, 29, 34, a, b

The middle number when the numbers are arranged in order is the median

Since we have 10 numbers, the median is the average of the 5th and 6th numbers:

Median = (28 + 29)/2 = 27

The mode is the most occuring number.

Here, the number 29 appears twice, which is more than any other number.

Since a < b, we know that a must be one of the numbers that appears earlier in the list.

Since the mode is 29, we know that b must be 29.

Finding the smallest possible integer value of k requires analyzing the given equation and determining the conditions under which one root is less than 1 and the other is greater than 1.

The equation is:

2^(2x) - 2(k-1)^(2x) + k = 0

Let's break down the conditions step by step.

1. Square root less than 1:

To make the square root less than 1, we need to substitute x = 1 into the equation and get a positive value. So if x = 1, then

2^(2*1) - 2(k-1)^(2*1) + k > 0

4 - 2(k-1)^2 + k > 0

Extensions and simplifications:

4 - 2(k^2 - 2k + 1) + k > 0

4 - 2k^2 + 4k - 2 + k > 0

-2k^2 + 5k + 2 > 0

2k^2 - 5k - 2 < 0 xss=removed xss=removed xss=removed xss=removed > 0.

Now we can combine both conditions to find the smallest integer value of k.

2k^2 - 5k - 2 < 0 > 0 (Condition 2)

By solving these conditions simultaneously, we can find the range of values of k that satisfy both conditions and determine the smallest integer value of k. However, this process requires calculations and algebraic manipulations beyond the scope of simple text-based answers.

It is recommended to use an algebraic calculator or software to solve the equation and find the smallest integer value of k that satisfies the given conditions.

Lilly is describing a parallelogram, which is a quadrilateral with two pairs of parallel opposite sides.

A parallelogram has opposite sides that are congruent and parallel, and opposite angles that are congruent. Therefore, it has two pairs of equal opposite sides.

There are two types of parallelograms: a rectangle and a rhombus. A rectangle is a parallelogram with four right angles, while a rhombus is a parallelogram with four congruent sides.

Both shapes have two pairs of equal opposite sides and opposite sides that are parallel.

Therefore, Robin is correct that there are two possible shapes. Depending on whether all four angles are right angles or all four sides are congruent, the shape could be a rectangle or a rhombus. It is also possible for a shape to be both a rectangle and a rhombus, in which case it would be called a square.

Start with the expression: 3/5 × (-6 + 2 2/3) ÷ 1 1/2 - 1 1/8 - 5/2 + (1 4/5 ÷ 9/10).

Simplify the addition and subtraction within parentheses first:

-6 + 2 2/3 = -6 + 8/3 = -18/3 + 8/3 = -10/3

1 4/5 ÷ 9/10 = 9/5 ÷ 9/10 = 9/5 × 10/9 = 90/45 = 2

Now the expression becomes: 3/5 × (-10/3) ÷ 1 1/2 - 1 1/8 - 5/2 + 2.

Next, let's simplify the division:

-10/3 ÷ 1 1/2 = -10/3 ÷ 3/2 = -10/3 × 2/3 = -20/9

The expression now becomes: 3/5 × (-20/9) - 1 1/8 - 5/2 + 2.

Now let's simplify the subtraction:

1 1/8 = 8/8 + 1/8 = 9/8

The expression becomes: 3/5 × (-20/9) - 9/8 - 5/2 + 2.

Convert all fractions to a common denominator:

The common denominator for 5, 9, 8, and 2 is 360.

Perform the multiplications:

(3/5) × (-160/72) = -480/360 = -4/3

(9/8) × (45/45) = 405/360 = 9/8

(5/2) × (180/180) = 900/360 = 5/2

(2/1) × (180/180) = 360/360 = 1

A = $100 x [tex]e^{0.033 * 6}[/tex]

A = $100 x [tex]e^{(0.198)}[/tex]

A = $100 x [tex]2.71828^{(0.198)}[/tex]

A = $100 x 1.2182

A = $121.820

Therefore, the amount in the account after 6 years of continuous compounding at an interest rate of 3.3% per year is $121.820.
