138 is the outlier since it is more than 1.5 * IQR past the third quartile of the data set.
With this upper outlier, the mean will be significantly higher. Without it, it will lower back down, so B is your answer
Answer:
16 : 28
Step-by-step explanation:
If 12 out of the 28 pupils are female, we can calculate the number of males by subtracting the number of females from the total number of pupils.
28 - 12 = 16
So, there are 16 males in the class. Now, we know that the ratio of males : total is 16 : 28.
I hope this helps! Have a lovely day!! :)

Answer:
1)
90g strawberry jelly
6 sponge fingers
315ml custard
135g tinned fruit
2) 260 cm²
Step-by-step explanation:
1) 120/4 × 3
90g strawberry jelly
8/4 × 3
6 sponge fingers
420/4 × 3
315ml custard
180/4 × 3
135g tinned fruit
2) area = base × height
= 20 × 13
= 260 cm²
The linear combination method involves multiplying, adding and subtracting in such a way that allows one variable to be eliminated in the addition or subtraction step. This leaves the other variable alone, allowing its value to be determined.
1. <span>5m+3n=41, 3m−6n=9
Multiply 1st equation by 2: 10m + 6n = 82
Add to 2nd equation: 13m = 91
Divide by 13: m = 7
Substitute back to 1st equation: n = 2
Therefore m = 7 and n = 2.
2. </span><span>6g+8h=40 −6g+2h=−20
Add both equations: 10h = 20
Divide by 10: h = 2
Substitute to 1st equation: g = 4
Therefore g = 4 and h = 2.
3. </span><span>9x+5y=35 2x+5y=0
Subtract 1st equation by the 2nd equation: 7x = 35
Divide by 7: x = 5
Substitute back to the 1st equation: y = -2
Therefore x = 5 and y = -2.
</span>
The slope is 3/1.
Hope this helped
