Two questions

melamori03 [73]

Use PEMDAS method to execute operations in the following order:

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

First equation:

12 + (38 - 18)2 = 12 + 20 × 2 = 52

Second equation:

(12)2 - 6(2 - 23) = 24 - 6(-21) = 24 + 126 = 150

Hope this helps.

Trying to help daughter solve problem. Where would you place the parentheses? 2x4+6-2+8/4=18

tiny-mole [99]

Here the order of operation is very important. I put few parenthesis to show you what is the correct result. First you have to multiply/divide, then u can add/subtract
$(2*4)+(6-2)+\frac{8}{4}=8-4+2=6$

3. Make a class frequency table using 2 rule of the following data. Find the Mean and make a Cumulative frequency Histogram [10]

sashaice [31]

Answer: Mean = 284

Step-by-step explanation:

Data:

125, 126, 127, 127, 137

201, 202, 207, 211, 215, 218, 224, 237, 261

301, 308, 310, 315, 330, 330, 360, 380, 393, 394

401, 401, 410, 421, 422, 424

Class Frequency Table:

$\boxed{\begin{array}{c|c|c}\underline{\text{Intervals}}&\underline{\text{\qquad Frequency\qquad}}&\underline{\text{Cumulative Frequency}}\\0-49&0&0\\50-99&0&0\\100-149&5&5\\150-199&0&5\\200-249&8&13\\250-299&1&14\\300-349&6&20\\350-399&4&24\\400-449&6&30\\450-499&0&30\end{array}}\\.\qquad \qquad \qquad \qquad \quad \ 30$

Mean:

The sum of the numbers divided by the quantity of numbers:

8518/30 = 283.933

Cumulative Frequency Histogram:

Create the graph based on the Interval and Cumulative Frequency of the class frequency table above. (see image)
