You must earn 243 points to have earned 93% of all possible points.
We first multiply each percentage on the previous tests by 150:
0.88*150 = 132
0.94*150 = 141
0.9*150 = 135
The total number of points possible is given by adding up the possible points for the three previous tests and the 250 for the last test:
150+150+150+250 = 700
93% of the 700 points would be 0.93(700) = 651 points.
Now we have 132+141+135+x (last test) = 651
408 + x = 651
Subtract 408 from both sides:
408+x-408 = 651-408
x = 243
<u>OPTION C</u>
if any doubt leave a comment
130 * 3 equals 390 so 390 is your answer
Answer:
3.61
Step-by-step explanation:
We need to use the distance formula for this:
Basically, we find the different between the the x points: -2-(-4)
Thats 2
Next we square 2 to get 4
Now we find the different between the y points: -3-0
Thats -3
Next we square -3 to get 9
Now, we add 9 to 4 to get 13
Finally, we take to square root of 13 to get 3.61
Have a nice day!
