Step-by-step explanation:
Linear pairs = 180°!!!!!
- 1st angle is 2[x]-39 2nd angle is just x
- soooo add the x. 3x-39=180
- 3x=141 x=47
X is just the second angle!!!!!
lol. i toonk geo last year and i cant believe i still remember all this hopefully i got it right!
Answer:
9.5
Step-by-step explanation:
1. Arrange in ascending order
4 5 6 7 8 9 10 11 12
2. Upper Quartile formula:
3×(N+1)÷4
3. Number of terms (N) = 9
4. Apply:
3×(9+1)/4
=3×10/4
=30/4
=7.5th term
5. 7.5th term is the average of the 7th and the 8th term so
Take average
7th term is 9 and 8th term is 10
6. Find average of 9 and 10 = 9.5
7. ANSWER : THE UPPER QUARTILE IS 9.5 FOR THE GIVEN DATA
Answer:
Rational Numbers: 1.1625, 5.15603418923, and -11/151
Irrational Numbers: √256, √141, and ∛25
Step-by-step explanation:
Rational Numbers are numbers that are decimals, fractions, and whole numbers.
Irrational Numbers are numbers that have square roots and cube roots.
It is given that there are 41 males and 48 females in the small school.
So, the number of ways a male student can be chosen from 41 males is 
Likewise, the number of ways a female student can be chosen from 48 females is
.
Thus, the total number of ways in which 2-person combinations are possible to represent the student body at the PTSAC meetings will be given by:

Answer:
x=18, y= 6
Step-by-step explanation:
if x+y=24
x= 24- y
in second case
x= 3y
24_ y = 3y
24=4y
y= 6
hence x = 24 _6 = 18
