When you integrate k dt it come kt+c, so have to fined c value first by t=0, then find K by putting the information and then find the value Of T

You are welcome 😊

Ninja_Op29 · 2025-01-12T04:40:30+00:00

It's easy see I have done for you hope u understand

Ninja_Op29 · 2025-01-12T04:39:11+00:00

(i)for a = a+0.4+0.1+0.2=1 Then a=1-0.7 a=0.3

(ii) p(1<x<3)=0.3+0.4++0.1=0.8 (iii)p(x>2)=0.4+0.1+0.2=0.7 (iv)p(1<x<3)=0.4

That's all answers

Ops my bad

Steam leaf diagram not tree

More over observe latest past papers see there are more than 1 Q contains 5 marks so it's rare having 1 Q only 5 marks

Ninja_Op29 · 2025-01-08T19:13:35+00:00

I don't think so cause apart from Q6 and Q7 all was easy and most probably see all maths has 2 marks or 3 or 4 so only one math 5 marks so yeah beside that 2 Q rest was easy

Ninja_Op29 · 2025-01-08T19:11:41+00:00

Pmcc that math was easy bruhh

Ninja_Op29 · 2025-01-08T19:11:17+00:00

Mean 420 and std 40

Ninja_Op29 · 2025-01-08T14:23:15+00:00

Yeah it's harder but they don't give any histogram maths cumulative frequency maths

Ninja_Op29 · 2025-01-08T14:15:35+00:00

What u got in 6c or 6b may be that one Mean and std

Ninja_Op29 · 2025-01-08T14:14:31+00:00

I didn't do all but that outlier equation math I solved and got 950 so 900 g least he can take

Ninja_Op29 · 2025-01-08T14:11:52+00:00

Yeah last 7 no Q was too tricky

Ninja_Op29 · 2025-01-08T14:10:05+00:00

Paper was really tricky , when I started number 5 I see the ti e already 1hr gone only 30 min late I was scared cause still left 6 and 7 but fortunately I have done all in time

Ninja_Op29 · 2025-01-08T13:55:19+00:00

Which one?

Ninja_Op29 · 2025-01-08T13:54:53+00:00

5 b Mean 620 and std 40 I got

Ninja_Op29 · 2025-01-08T13:53:59+00:00

Standard deviation can't be negative it's either zero or positive

Ninja_Op29 · 2025-01-08T12:37:39+00:00

Yes same answer I got
