During a quality assurance check, the actual contents (in grams) of six containers of protein powder were recorded as 1530, 1

Fofino [41]

Answer:

Step-by-step explanation:

Given the values of the actual content of protein powder recorded as shown:

1530, 1532, 1495, 1508, 1528, and 1511

a) We are to find the mean and median of the contents.

Mean is the average sum of the numbers. It is expressed mathematically as xbar = ΣXi/N

Xi are individual values

N is the total number of values present.

N = 6

xbar = (1,530+1,532+1,495 +1,508+1,528+1,511)/6

xbar = 9104/6

xbar = 1517.33

Median of the data is the value at the middle after rearrangement. On rearranging from lowest to highest:

1,495, 1508, 1511, 1528, 1530, 1532

The two values at the centre are 1511 and 1528.

Median = 1511+1528/2

Median = 1519.5

b) If the third value was incorrectly measured and is actually 1515, then our new data will become.

1530, 1532, 1515, 1508, 1528, and 1511

xbar = (1,530+1,532+1,515 +1,508+1,528+1,511)/6

xbar = 9124/6

xbar = 1520.67

For median:

We arrange first

1508, 1511, 1515, 1528, 1530, 1532

The two values at the centre are 1515 and 1528.

Median = 1515+1528/2

Median = 1521.5

c) To know the measure of central tendency that was most affected, we will look at the difference in the values gotten for both mean and median.

∆Mean = 1520.67-1517.33

∆Mean = 3.34

∆Median = 1521.5 - 1519.5

∆Median = 2.0

It can be seen that the measure of central tendency with greater deviation is the mean. Therefore, the mean is more affected by the data entry error.

A circle is drawn within a square as shown. What is the best approximation for the area of the shaded region? Use 3.14 to approx

puteri [66]

The answer is around 168.56

work :

the side of the square is 28 in

so the diameter of the circle is 28 in, too(look at the picture)

then the radius is 14 (28/2)

the area of the circle is
$(14 \times 14) \times 3.14 = 615.44$

the area of the square is
${28}^{2} = 784$

so the area of the shaded region will be around:
$784 - 615.44 = 168.56$

good luck
