X=1 and y=-2
In ordered pairs it would be (1,0) and (0,-2)
Mean = total score : frequency
mean x frequency = total score
so
83 = total score : 6
83 × 6 = total score
498 = total score
so the sum of the 6 test scores is 498
Answer:
43/100
Step-by-step explanation:
It would have to be 43/100 becuase 43 is a prime number, therefore it cannot be simplified.
<u>Solution</u><u> </u><u>:</u><u>-</u>
This triangle is a right angled triangle as we can see ∠POC, has a right angled sign. Now, we will assume the missing angle to be x, thus,
25° + 90° + x = 180° ( Angle sum property of a triangle )
115° + x = 180°
x = 180° - 115°
x = 65°
Thus, the measure of missing angle is 65°.
Hope that helps. :D
