Linear pairs = 180°!!!!!

1st angle is 2[x]-39 2nd angle is just x
soooo add the x. 3x-39=180

Find the upper quartile of the given data below:<br> <br> 11, 8, 5, 4, 7, 6, 9, 10, 12

JulijaS [17]

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

at a small school, one male and one female are selected to represent the student body at the PTSCA meetings. if there are 41 mal

I am Lyosha [343]

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 $^{41}C_1$

Likewise, the number of ways a female student can be chosen from 48 females is $^{48}C_1$ .

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:

$^{41}C_1\times ^{48}C_1=1968$

8. Solve X=Students & Y=Teachers<br> X+Y=24<br> X=3Y

Len [333]

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
