So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8

Hope this helped
The stem and leaf diagram is shown below
There are a total of 48 data
Question a:
The frequency in the stem for 9 to 9.9 is 13 data
Question b:
The location of the first quartile is given by

, where 'n' is the number of data
We have n = 48
Location of the first quartile is at

rounded down to 12
The value of the lower quartile is on the

on the diagram which is 8.7
Answer:

Step-by-step explanation:
We will use the co-function identity for sine, where:

Since sin(21)=0.358=cos(x). This means that:

Solve for x. Add x to both sides:

Subtract 21 from both sides:

Hence:
