{2}^{2} \times 3

20 : 2 × 2 × 5. Also can be written as
{2}^{2} \times 5

30 : 2 × 3 × 5

56 : 2 × 2 × 2 ×7. Also can be written as
{2}^{3} \times 7

70 : 2 × 5 × 7

You can find all of them by using Factor Tree [ as shown in the picture] or Dividing by prime numbers.

Drag the simplified value into the box to match each expression.
Maru [420]

Answer:

The answers are as follows: 12 106 42

Step-by-step explanation:

Given: $ 18 - 4^2 + 5 \times 2 $  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate $ 18 - 4^2 $ separately and $ 5 \times 2 $ separately and add them. So we have $ 18 - 16 + 10 = 2 + 10 =12 $.

Now for the second question: $ 9^2 + 4 \times 7 - 3 $. we would get $ 81 + 28 - 3 = 106 $

Next, $ 5^2 - 4 + 7 \times 3 $. This could be written as:  $ 25 - 4 + 21 = 42 $. Hence the answers.

Data Set #1
Harman [31]

Answer:

The data table is attached below.

Step-by-step explanation:

The average of a set of data is the value that is a representative of the entire data set.

The formula to compute averages is:

\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}

Compute the average for drop 1 as follows:

\bar x_{1}=\frac{1}{3}\times[10+11+9]=10

Compute the average for drop 2 as follows:

\bar x_{2}=\frac{1}{3}\times[29+31+30]=30

Compute the average for drop 3 as follows:

\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33

Compute the average for drop 4 as follows:

\bar x_{4}=\frac{1}{3}\times[102+100+98]=100

Compute the average for drop 5 as follows:

\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67

The data table is attached below.
