Ella must make a 93 to create a classroom mean test score of 90
Arrange the numbers in order from smallest to largest:
28, 35, 40, 40, 45, 52, 54, 58, 60
Median is the middle value = 45
Mode is the number that appears most = 40
Mean is the average. Add the numbers and divide:
412/9 = 45.77 = 45.78
Range is difference between highest and lowest = 60 - 28 = 32
The sentence sequence is "BDAC".
<u>Step-by-step explanation</u>:
- Derek is rolling a die many times and he is recording when he rolls a dice of three. So we have to identify from largest to smallest.
- The first largest is 30 times. Because of 3*10=30, so he rolls three ten times. So the first option is B.
- The second largest is 20 times. Derek rolled dice three-six times because of 3*6=18. So the second option is D.
- The third-largest is 10 times. In this, he rolls three times. Because of 3*3=9. So the option is A.
- The final option is C. Derek rolls five times. 3*1=3. In this, he rolled only one time. So the sequence is BDAC.
Twice the abscissa increased by three times the ordinate is 10.
x - the abscissa;
y - the ordinate.
Answers A and B represents: "Three times the abscissa increased by twice the ordinate is 10." Therefore A are B are wrong.
Answer:
C ) 2 x + 3 y = 10
