Step-by-step explanation:
Given: The mean score for a math test taken by Class A is 84, with the scores ranging from 78 to 94. The mean score for the same math test taken by Class B is 76, with the scores ranging from 68 to 88
a) Incorrect: The highest score was in Class A which is 94
b) Incorrect: The average of Class A is 84 which is higher than Class B is 76
c) Correct : The average of Class A is 84 which is higher than Class B is 76
d) Incorrect: The difference between highest and lowest scores in Class A is 16(94-78) whereas in Class B its 20(88-68)
Answer:
D
Step-by-step explanation:
-2 | -8
-1 | -24
0 | -10
1 | 2
2 | 3
Graph D:
point 1. -2 , -8
point 2. -1 , -24
point 3. 0 , -10
point 4. 1 , 2
point 5. 2 , 3
if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5
so, that means that 1.5(2x+6) = 4x+2
so, your equation becomes 3x+9 = 4x+2
if you subtract 2 from each side, you get 3x+7 = 4x
meaning that x = 7
i hope this helps, and i'm sorry if it's wrong!! :)
Answer:
There will be 200 000 bacteria after 8 hours
Step-by-step explanation:
The crop quadruples every hour.
x represents the number of hours that pass after preparing the crop
y represents the number of bacteria after x hours.
The equation for y in function of x 3 hours after observing the crop is:
We want to know after how long there will be 200 000 bacteria.
Then we make y = 200 000 and clear x.
Answer:
B is the answer
Step-by-step explanation: Ok so the problem we are working with is
8 2/9-4 2/3. We will eliminate all the negative answers. So we only have 2 options. When we actually think logically B is the only possible answer.
