A cross product is an equation which states that two ratios are equal. True False
Answers
It is true that a cross product is an equation that states that two ratios are equal. For example, if a player's batting average is 400 out of 1000, and you wanted to know how many times they will hit every 50 times batting, then you would set the equation up at 400/1000 and equal that to X/50, then you would use cross product to find the answer.
45% of the beads in a box are blue. if there are 36 blue beads in the box, how many beads are there altogether ?
Answers
Breaking down the numbers shows that if 45% is 36 beads, then 5% is 4 beads (divide by 9). Then multiply 5% by 20 (to get 100%) and 4 beads by 20 (distributive property) to have 80 beads.
36÷0.45=80 There are 80 beads altogether

Answers
To solve this question, you¨ll need to use a table of the standardized Normal distribution, or you could use a graphing calculator. The answer will be the cumulative property which will be a number with decimals. However, this represents the students who had a lower score then her, You´ll need to subtract this from 1 in order to get the opposite number, which will be the kids who scored higher. Be sure to multiply the result by 100 to get a percentage. Your answer should be 0.806 hope this helped!
