Answer:
should be 30
Step-by-step explanation:
triangles have 180°
if x is 30
2x is 60
the other angle is 90
add those all together and you get 180°
1)12 ÷ 3 = 4.
2) 4×2= 8.
3) 9× 8= 72.
4) 8² = 64
5) 64+ 72 = 136
6) 136 - 7 = 129.
If you just want to simplify the expression you get: 8² + 9(8) - 7
But when you simplify that you get the answer below.
ANSWER: 129

Answer:
It is a discrete variable
Step-by-step explanation:
Discrete data take particular values, while continuous data are not restricted to separate values.
Discrete variable contains a certain number or unique number(like a whole number), a discrete variable is countable and you can know the exact number.
So number of student reading statistics book is a unique number and countable. A continuous number can be a real number e.g(2.3, 5.678) etc
So the statistic student reading book can be 10, 34, 1000, 356, etc
But the statistic student reading the book can't be 1½, 56⅔, 7.6. We can't have two and a half people, it is either 2 or 3 people.
