Answer:
The answer for first one is,

sorry I don't know the answer for second one.
Answer:
Mode
Step-by-step explanation:
Mean:
Before replacing = 464/8 = 58
After replacing 42 with 98 = 520/8 = 65
Mode:
Before replacing = 42
After replacing 42 with 98 = 98
Median:
25, 42 , 42 , 47, 55 , 59, 96,98
Before replacing = 47+55/2 = 51
25, 42 , 47, 55 , 59, 96,98 , 98
After replacing 42 with 98 = 55+59/2 = 114/2 = 57
Answer:
option 2 I think sorry if its incorrect
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
Step-by-step explanation:
Let,
The longer leg = x
The shorter leg = x-7
Hypotenuse = x+7
Using Pythagoras theorem;

Either,
x= 0
Or,
x-28=0 =>x=28
As length cannot be zero, therefore,
Longer side = 28cm
Shorter side = x-7 = 28-7 = 21cm
Hypotenuse = x+7 = 28+7 = 35cm
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.

Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23
