If the 5 scores have a mean of 8, then their total sum would be 8*5 = 40
Now if one score if added (let's call this score x), there are 6 scores and the mean changes to 9, thus:
(40 + x)/6 = 9
40 + x = 54
x = 14
Step-by-step explanation:
K=12 if you want explanation i will
Answer:bh
345
Step-by-step explanation:
y is in direct proportion to x. x = 25, y = 5. Find the value of y, if x = 9.
3+5=8
1200 voters
1200/8 = 150
Female: 5 x 150 = 750 voters
Male: 3 x 150 = 450 voters
Answer: x = 156°
Step-by-step explanation:
So it is proven all triangles equal 180° and all straight angles are 180° so
85+71= 156
180-156=24°
but since you are trying to find x (to create the straight angle) and now know the other missing angle is 24°
180-24= 156
x=156°
