Math:
This is an average that takes into account the frequency of

each value.

• median
• weighted mean

• mode
• mean

Math:
What is the mode in the following dataset?

6, 4, 7, 6, 2, 4, 7, 8, 6, 10, 7

• 4, 7

• 4

• 6, 7
• 6

Answer explanation

Math:

What helps you predict how likely an event is to occur?

• Median

• Chance
• Analyzing

• Probability

Math:

What type of chart is this?

• Bar Chart
• Pie Chart
• Line Graph
• Stenograph

Math:

How many 4 digit pin codes can be made using the numbers 0 to 9 if repetition of digits is

allowed?

• 9999
• 1000
• 5000
• 10000

Answer explanation

10 x 10 x 10 x 10 = 10000

(Repeating is allowed)

Math:

Simplify 10x + 5x + y + 9y

• 15x + 10y

• 10x + 7y
• 7x + 10y
• 8x + 10y

Answer explanation

If a variable is by itself (ex: y) it's always viewed with an imaginary 1 (ex: 1y)

Math:

Multiply 2x, 7x, and 10y

• 20x³y

• 140x²y

• 140xy
• 70x2y

Answer explanation

Multiply the coefficients (the numbers next to the variable) example, The 7 in "7x" is the coefficient.

If there is multiple of the same variable, add the exponents of the same variable.

(The variable is the letter in the problem)

(Ex: [x] [x²] becomes [x¹⁺²])

Math:

Kirk rolled a six-sided die 20 times, he got the number "4" 7 out of 20 times.

7/20 is what type of probability?

• Experimental probability

• Conditional probability
• Probably idk

• Theoretical probability

Answer explanation

hi kirk

Math:

Reese and Jaeden are arguing about the differences of primary sources and secondary sources,

what is the difference between primary and secondary sources?

• Primary sources are always digital; secondary sources are always print.
• Primary sources are summaries of events; secondary sources are firsthand accounts.
• Primary sources are less reliable than secondary sources.
• Primary sources are original materials; secondary sources analyze or interpret those materials.
