Step-by-step explanation:
When the graph of a relation is a straight line, the relation is said to be "linear." When the graph of the line goes through the origin (x, y) = (0, 0), then the relation is both "linear" and "proportional."
The "rate of change" of a line is the ratio of "rise" to "run". On a graph of a line, it is convenient to determine "rise" and "run" using points where the line crosses grid intersections. Of course, there is a crossing here at (0, 0). We notice another grid intersection crossing at the point corresponding to x=2 and y = -6. Then the "rise" (y-change) divided by the "run" (x-change) is ...
rate of change = rise/run = -6/2 = -3
__
The equation of a line representing a proportion is of the form ...
y = kx
for some constant k. That constant is the "rate of change" of the proportion. Here, we found that rate of change to be -3, so the equation of the line is ...
y = -3x

The compressive strengths of 40 concrete cylinders have an estimated mean of 60.14 MPa and standard deviation of 5.02 MPa. Assuming the strength to be Normally distributed, what is the probability that 10 cylinders will each have strengths between 45 and 75 MPa?
Answers
Answer: 0.9972
Step-by-step explanation:
Let x be a random variable that represents the strength of concrete cylinders.
Given: The compressive strengths of 40 concrete cylinders have an estimated mean[tex](\mu)[/tex] of 60.14 MPa and standard deviation[tex](\sigma)[/tex] of 5.02 MPa.
The probability that 10 cylinders will each have strengths between 45 and 75 MPa :
[tex]P(45<\overline{x}<75)=P(\dfrac{45-60.14}{5.02}<\dfrac{\overline{x}-\mu}{\sigma}<\dfrac{75-60.14}{5.02})\\\=P(-3.016<z<2.96)\\\\=P(z<2.96)-P(z<-3.016)\\\\=P(z<2.96)-(1-P(z<3.016))\\\\=0.9985-(1-0.9987)\ \ \ [\text{by p-value table}]\\\\= 0.9972[/tex]
Hence, The required probability = 0.9972

The measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Z is the centroid of triangle.
The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle.
WR=87 SY=39 and YT=48
We need to find WS,WY,WZ,ZR,ZT and YZ
WS=39
As WS=WR
WY=WS+SY
WY=39+39=78
WZ=58
ZR=WR-WZ
ZR=87-48=29
ZT=16
YZ=YT-ZT
=48-16=32
YZ=32
Hence, the measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

The sum of the ages of Peter and Paul is 24. Five years ago their respective ages were in the ratio 3:4. How old will they be in three years time?
Answers
Answer:
16 and 14 years old.
Step-by-step explanation:
Let their ages be x and y years, then
x + y = 24 .......... (1)
Also from the given information
(x - 5)/ (y - 5) = 3/4
3y - 15 = 4x - 20
3y - 4x = -5
Multiplying equation (1) by 3:
3y + 3x = 72
Subtracting these last 2 equations:
-7x = -77
x = 11.
So y = 24 - 11 = 13.
So in 3 years time they will be 16 and 14.
Answer:
Peter would be 14. Paul would be 16
Step-by-step explanation:
Variable labels:
Peter = m, Paul = n
m + n = 24
(m - 5) : (n- 5) = 3:4
The ratio 3:4 in fraction form is [tex]\frac{3}{4}[/tex]
The ration of (m - 5) : (n- 5) in fraction form is [tex]\frac{m - 5}{n - 5}[/tex]
[tex]\frac{m-5}{n-5} = \frac{3}{4}[/tex]
Cross multiply:
4(m - 5) = 3(n - 5)
4m - 20 = 3n - 15
4m = 3n + 5
Find the value of m first:
4m = 3n + 5
m = [tex]\frac{3n + 5}{4}[/tex]
Now going back to the equation m + n = 24, substitute m with [tex]\frac{3n + 5}{4}[/tex] :
m + n = 24
[tex]\frac{3n + 5}{4}[/tex] + n = 24
Solve for n:
[tex]\frac{3n + 5}{4}[/tex] + n = 24
[tex]\frac{3n}{4} + \frac{5}{4}[/tex] + n = 24
[tex]\frac{7n}{4} +\frac{5}{4}[/tex] = 24
[tex]\frac{7n}{4} = \frac{91}{4}[/tex]
n = 13 (Paul's age)
Solve for m:
m + n = 24
m + 13 = 24
m = 11 (Peter's age)
After three years, Peter would be 11 + 3 = 14 years old and Paul would be 13 + 3 = 16 years old.

Some of the steps in Liam solution to 3. 5 (1.25x + 0.5) = 10.5 are shown complete the boxes with reasons for lines 2 and 4 of Liam solution
Answers
Answer:
x = 2
Step-by-step explanation:
Given the equation;
3. 5 (1.25x + 0.5) = 10.5
Open the parenthesis
3.5(1.25x) + 3.5(0.5) =10.5
4.375x + 1.75 = 10.5
4.375x + 1.75 -1.75= 10.5-1.75
4.375x = 8.75
Divide both sides by 4.375
4.375x/4.375 = 8.75/4.375
x = 2
Hence the solution to the equation is 2
