Answer:
45 and 47
Step-by-step explanation:
Answer:
3/8
Step-by-step explanation:
Looking at the bottom row, there are 8 possible outcomes
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT
There are 3 that have exactly 2 heads HHT, HTH, THH,
That means the probability is
P( exactly 2 heads) = number outcomes with exactly 2 heads/total outcomes
=3/8
question 1=30
question 3 =1/20
Step-by-step explanation:
question 1
- 300/2×5
- 300/10
- 300\10 you will take by 0 0
- so the ans is 30/1
- answer is 30
question 2 am not sure
question 3
- it is 20/1
- so the reciprovol of 20/1 is 1/20
- that's all I know for no 2 I will some one. thanks
If a² + b² = c², then the triangle is <u>right</u>.
So we have (8)² + (11)² <u>?</u> (13)²
(8)² is 64, (11)² is 121, and (13)² is 169.
So we have 64 + 121 <u>?</u> 169
64 + 121 is 185 and we can see that 185 > 169.
This triangle would not be a right triangle.
In fact, it would be an acute triangle.
So no, it's not a right triangle.
