Find and interpret the mean absolute deviation of the data.

Answers

Answer:

The mean absolute deviation is 4

Interpertation: The average distance between each data value and the mean is 4 which is the variation in the data set so you can understand how "spread out" each data point is from each other

Step-by-step explanation:

The mean absolute deviation is a measure of how much a data set varies.

Step 1: Compute the mean

mean = the sum of all the terms / number of terms

mean = 94 + 86 + 95 + 99 + 88 + 90 / 6

= 552 / 6

= 92

The mean is 92

Step 2: Finding the absolute deviation

You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values

= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|

= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|

= 2 + 6 + 3 + 7 + 4 + 2

= 24

To find the mean absolute deviation you divided the sum by total number of terms...

24/6 = 4

The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)

A pair of equations is shown below:

y = 7x − 8
y = 5x − 2

Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.

Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer

Answers

Answer:

x = 3

(3, 13)

Step-by-step explanation:

Given equations:

y = 7x − 8y = 5x − 2

Part A

Solve by substitution:

⇒ y = y

⇒ 7x - 8 = 5x - 2

Subtract 5x from both sides:

⇒ 7x - 8 - 5x = 5x - 2 - 5x

⇒ 2x - 8 = - 2

Add 8 to both sides:

⇒ 2x - 8 + 8 = - 2 + 8

⇒ 2x = 6

Divide both sides by 2:

⇒ 2x ÷ 2 = 6 ÷ 2

⇒ x = 3

Part B

To find the y-value of the point of intersection, substitute the found value of x (from part A) into one of the equations:

⇒ y = 7(3) - 8

⇒ y = 21 - 8

⇒ y = 13

Therefore, the point at which the lines intersect is (3, 13)

(3, 13) where x is 3 and y is 13

Find the area of the circle. Round your answer to the nearest hundredth.

Answers

Answer:

5.55

Step-by-step explanation:

area= πr^2

1.5/2=0.75

0.75x 3.14= 2.355

2.355^2=5.546025

=5.55

Answer:

Area of circle = 1.77 ft²

Step-by-step explanation:

Given that,

→ Diameter = 1.5 ft

→ Radius (r) = 1.5/2 = 0.75 ft

Formula we use,

→ Area of circle = πr²

Then the area of circle will be,

→ πr²

→ 3.14 × 0.75 × 0.75

→ 1.76625

→ 1.77 ft²

Hence, the solution is 1.77 ft².

Answers

Answer:

Step-by-step explanation:

To find the circumference of a circle, we use the formula:

Circumference = 2 * π * radius

Let's calculate the circumferences for the given options

1. Circumference = 2 * 3.14 * 53 ≈ 333.64 cm

2. Circumference = 2 * 3.14 * 227 ≈ 1428.28 cm

3. Circumference = 2 * 3.14 * 20 ≈ 125.6 cm

4. Circumference = 2 * 3.14 * 27 ≈ 169.56 cm

now, rounding each value to the nearest unit , we get

1. Circumference ≈ 334 cm

2. Circumference ≈ 1428 cm

3. Circumference ≈ 126 cm

4. Circumference ≈ 170 cm
