Answer:

x ≈ 45.6°

Step-by-step explanation:

using the Cosine rule in the triangle

cos x = [tex]\frac{8^2+15^2-11^2}{2(8)(15)}[/tex] = [tex]\frac{64+225-121}{240}[/tex] = [tex]\frac{168}{240}[/tex] , then

x = [tex]cos^{-1}[/tex] ( [tex]\frac{168}{240}[/tex] ) ≈ 45.6° ( to 1 dec. place )

The circumference of a circular garden is approximately 20 feet. What is the approximate area inside the circular garden?

Answers

Answer:

31.85 square feet

Step-by-step explanation:

Finding the radius :

C = 2πr20 = 2πrr = 20/2πr = 10/π

Substituting in the area formula :

A = πr²A = π × 10/π x 10/πA = 100/πA = 100/3.14A = 31.85 square feet

So

2πr=20πr=10r=10/π

Now

Area

πr²πr(r)10r10(10/π)100/π31.8ft²

Melody need 155 bags of 140 cu. inches to fill the vegetable garden.

What is Volume of Cuboid?

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.

Here, Length of vegetable garden = 48 inch

          breadth of garden = 30 inches

          height of garden = 15 inches

Volume of garden = Length X width X height

                              = 48 X 30 X 15

                              =  21600 cu. inches

Volume of each bag = 140 cu. inches

Number of Bags required = Volume of garden/Volume of each bag

                                            = 21600 / 140

                                            ≈ 155

Thus, Melody need 155 bags of 140 cu. inches to fill the vegetable garden.

A and B are independent events. If P(A) = 0.50 and P(A and B) = 0.20, find P(B).

Answers

The independent events are illustrations of probability, and the value of P(B) is 0.40

How to determine the value of P(B)?

The given parameters are:

P(A) = 0.50

P(A and B) = 0.20

Two events A and B are independent, if

P(A and B) = P(A) * P(B)

So, we have:

0.50 * P(B) = 0.20

Divide both sides by 0.50

P(B) = 0.40

Not only would I like the value of x, but also I wonder how I’d go about solving this problem?

Answers

Answer:

x = 58

Step-by-step explanation:

This question can be solved by using the exterior angle property, which states that the exterior angle of a triangle = the sum of the two opposite interior angles.

62 lies on a line, so the exterior angle is 180 - 62, or 118 degrees.

Using the EAP, we can conclude the following:

(x + 2) + (x) = 118

2x + 2 = 118

2x = 116

x = 58

Hope this helps

Answer:

X=58

Step-by-step explanation:

1.)  62+2+2x=180  

2)  64+2x=180    (add 62 and 2)

3) 2x=116  (subtract 64 from 180)

Answer: x + 4

Step-by-step explanation:

    If it is asking us for (f - g)x, then we will subtract the function g from function f. Why? The x distributes creating f(x) - g(x), so we use this to solve.

   Given:

g(x) = 2x - 2

f(x) = 3x + 2

   Set up:

f(x) - g(x)

(3x + 2) - (2x - 2)

   Distribute the negatie:

3x + 2 - 2x + 2

   Reorder to combine like terms:

Answer:

57

Step-by-step explanation:

This is because, in order to find the range you need to set the order from lowest to highest and subtract the lowest from the highest. So in this case the lowest would be 117 and the highest would be 174. So when you subtract them you get 57.

Answer:

1) Range = 57

2) Range = 12

3) Median = 88, First Quartile = 84,  Third Quartile = 92, Interquartile = 8

4) Median = 81.5, Median of lower half = 67, Median of upper half = 92,

Describe the spead of the data = ______

*We cannot see the drop-down answer choices for this part of the question, so we cannot give an answer. Sorry.

5) a. Range = 172 points, Interquartile Range = 42 points

b. Outlier = 193, Range without the Outlier = 101 points, Interquartile Range without the Outlier = 48.5 points

c. The outlier affected the __________ more.

*We cannot see the drop-down answer choices here, so we cannot answer this part of the question. Sorry.

Good Luck!  I hope this helps!

Step-by-step explanation:

1) Find the range of the data.

133, 117, 152, 127, 168, 146, 174.

First, put the numbers in ascending order:

117, 127, 133, 146, 152, 168, 174

To find the range, subtract the smallest number from the largest number.

174 - 117 = 57

So, the range is 57.

2) Find the range of the data.

26, 21, 27, 33, 24, 29

First, put the numbers in ascending order.

21, 24, 26, 27, 29, 33

To find the range, subtract the smallest number from the largest number.

33 - 21 = 12

So, the range is 12.

3) Find the median, first quartie, third quartile, and interquartile range of the data. 84, 75, 90, 87, 99, 91, 85, 88, 76, 92, 94

First, put the numbers in ascending order.

75, 76, 84, 85, 87, 88, 90, 91, 92, 94, 99

The median is the value in the middle, so in this case, it is 88.

To find the first quartie, third quartile, and interquartile, we must split the numbers into quarters.

75  76      84      85  87       88     90  91      92      94  99

The first quartile is 84.

The third quartile 92.

The interquartile is the first quartile subtracted from the third quartile, so

92 - 84 = 8.

4) Use grid paper to find the median of the data. Then find the median of the lower half and the median of the upper half of the data.

82, 62, 95, 81, 89, 51, 72, 56, 97, 98, 79, 85

First, put the numbers in ascending order.

51, 56, 62, 72, 79, 81, 82, 85, 89, 95, 97, 98

Find the median which is the middle of the values.

51  56  62  72  79    81  82    85  89  95  97  98

In this case, it is between 81 and 82, so we find 81+82 / 2 = 81.5.

The median is 81.5.

The median of the lower half of the data is the value in the middle of the first 6 of the 12 numbers.  51  56    62  72    79  81

We need to find 62+72 / 2 = 134 /2 = 67, so the median of the lower half of the data is 67.

The median of the upper half of the data is the value in the middle of the last 6 of the 12 numbers.  82  85    89  95    97  98

We need to find 89+95 / 2 = 184 / 2 = 92, so the median of the upper half of the data is 92.

Describe the spread of the data.

The data are ___________ . (We cannot see the drop-down options, so cannot answer this part of the question. Sorry.)

5) The table shows the number of points scored by players on a basketball team.  21  53  74  82  84  93  103  108  116  122  193

a. Find the range and interquartile range of the data.

To find the range, subtract the smallest number from the largest number.

193 - 21 = 172

The range is 172 points.

To find the interquartile range, we must split the numbers into quarters.

21  53      74      82  84      93      103  108      116      122  193

The first quartile is 74. 

The third quartile 116.

The interquartile is the first quartile subtracted from the third quartile, so 

116 - 74 = 42.

The interquartile range is 42 points.

b. Use the interquartile range to identify the outlier(s) in the data set.

Find the range and the interquartile range of the data set without the outlier(s).

21  53  74  82  84  93  103  108  116  122  193

Per Wikipedia, "In statistics, an outlier is a data point that differs significantly from other observations."

Per statology.org, "One popular method is to declare an observation to be an outlier if it has a value 1.5 times greater than the interquartile (IQR) or 1.5 times less than the IQR."  

From statology. org:

(Note: Q1 = first quartile, Q3 = third quartile, IQR = interquartile)

The lower limit is calculated as:

Lower limit = Q1 – 1.5 * IQR = 74 – 1.5 * 42 = 74 - 63 = 9.

The lower limit of outliers is 9 points.

And the upper limited is calculated as:

Upper limit = Q3 + 1.5 * IQR = 116 + 1.5 * 42 = 116 + 63 = 179.

The upper limit of outliers is 179 points.

The outlier is 193 points.

To find the range without the outlier, subtract the smallest number from the largest number.

21  53  74  82  84  93  103  108  116  122

122 - 21 = 101 points

The range without the outlier is 101 points.

To find the interquartile range wthout the outlier, we must split the numbers into quarters.

21      53  74      82      84  93      103      108  116      122

The first quartile is 53+74 / 2 = 127 / 2 = 63.5. 

The third quartile 108+116 / 2 = 224 / 2 = 112.

The interquartile is the first quartile subtracted from the third quartile, so 

112 - 63.5 = 48.5.

The interquartile range without the outlier is 48.5 points.

c. Which measure did the outlier affect more?

The outlier affected __________ more. (We cannot see the drop-down options, so cannot answer this part of the question. Sorry.)
