"base 10" and base system -any number times 10,100,1000.... you multiply the first digit by that number then add those amount of zeros to the end of the number (ie. 375 x100=37500) -any number divided by 10,100,1000... you divide the first digit by that number then move the decimal to the left according to the amount of zeroes (ie. 375/1000= .375) --this is done with any cardinal numbers A cardinal number tells "how many." Cardinal numbers are also known as "counting numbers," b...

Six children have collected these amounts in their piggy banks: $10, $33, $45, $23, $1, and $68. What is the median of their savings? a. $28 b. $33 c. $23 d. $66 answer: a. $28 Rearrange the numbers in increasing order: 1, 10, 23, 33, 45, and 68. The median of a sequence of numbers is the middle value. Since there are six numbers, there are two values in the middle 23 and 33 and, therefore, the median is the average of these values. The median is 28. What do you call questions th...

Integers Positive and Negative Whole Numbers; Includes 0 Prime Number A whole number greater than 1 that only has two factors (itself and 1) Composite Number A whole number greater than 1 that has more than two different factors Rational Numbers All integers, decimals and fractions; any terminating or repeating decimal number Irrational Numbers Cannot be written as fractions or decimals because the number of decimal places is infinite and there is no recurring pattern of digits within ...

Which of the following expresses 3/16 3 16 as a percent? A. 0.1875% B. 1.875% C. 5.33% D. 18.75% - Correct Answer: D Option (D) is correct. The question requires an understanding of percent and percentages. To convert a fraction to a percent, it is necessary to multiply the fraction by 100 and add a percent symbol. Since 316×100=18.75 3 16 × 100 = 18.75, 3 16 is equivalent to 18.75%. Which of the following is equal to 4(5−2)^2 − 2^3 (^ means the digit after ^ is an expon...

MATH PRAXIS TEST QUESTIONS AND ANSWERS LATEST UPDATE 2024/2025 | GRADED. Which of the following is equal to 4(5−2)^2 − 2^3 (^ means the digit after ^ is an exponent) A. 16 B. 28 C. 76 D.136 - Option (B) is correct. The question requires an understanding of the order of operations. The first step to simplify the expression 4(5−2)^2 − 2^3 is the evaluation of the subtraction within the parentheses; the expression is equivalent to 4 × 3^2 − 2^3 The second step is the evaluati...
