Hello, there!
Matthew is 8 years older than his brother. Use b to represent how old Matthew's brother is.
This means that Matthew's brother is 8 years younger than Matthew.
We will let 'M' represent Matthew's age and 'B' represent Matthew's brother's age.
The equation to represent this situation would be:
B = M - 8
I hope I helped!

Answer:
Step-by-step explanation:
To Test :-
H0 :- P = 0.12
H1 :- P ≠ 0.12
P = X / n = 156/800 = 0.195
Test Statistic :-
Z = ( P - P0 ) / ( √((P0 * q0)/n)
Z = ( 0.195 - 0.12 ) / ( √(( 0.12 * 0.88) /800))
Z = 6.5279
Test Criteria :-
Reject null hypothesis if Z > Z(α/2)
Z(α/2) = Z(0.05/2) = 1.96
Z > Z(α/2) = 6.5279 > 1.96, hence we reject the null hypothesis
Conclusion :- We Reject H0
There is sufficient evidence to support the claim that there is a difference.
We will use the formula for finding the surface area of a rectangular prism.
Formula =
SA <span>= </span><span>2 </span><span>(</span><span>w</span><span>l</span><span>+</span><span>h</span><span>l</span><span>+</span><span>h</span><span>w</span><span>)</span>SA = 2 (8·14 + 4·14 + 4·8)
SA = 2 (112 + 56 + 32)
SA = 2 (200)
SA = 400

Answer: b.97
97+37+46=180
Let 70% of X = 98
70%.x = 98
(70/100).x = 98
0,7x = 98
x = 98/0,7
x = 140
Then, 90%x = 90%.140
= 0,9.(140)
= 126
The answer to this question is Letter D)
I hope this has helped.
