Answer:
a. £2,500
b. £3,125
Step-by-step explanation:
The computation is shown below:
a. The original monthly expenditure is
Let us assume the original monthly expenditure be x
Monthly expenditure = x -15% of x
£2,125 = x - 0.15x
£2125 = 0.85x
x = £2125 ÷ 0.85
= £2,500
b. Now the monthy income is
Let us assume the monthly income be y
£2,500 = 80% of monthly income
£2,500 = 80% of y
y = £2,500 ÷ 80%
= £3,125
Answer:
1) Angle AOC + Angle COB = Angle AOB
Angle AOC = X
Angle COB = Y
putting in equation, we get
X + Y = AOB
2) Angle X + Y = AOB (proved above)
AOB = 90° ( given)
Angle X + Angle y = 90°
Angle X is the complement of Y
More likely -You are more likely to commit a Type I error
According to statement
we have to find the type 1 error by using the significant levels.
we are commit a MORE LIKELY to find the error by rejecting a true null hypothesis using the 0.05 level of significance than using the 0.01 level of significance.
So, More likely -You are more likely to commit a Type I error

Answer: go out with their girlfriends
Step-by-step explanation:
you a king
1.25 + 0.75x = 5.45 <== ur equation
0.75x = 5.45 - 1.25
0.75x = 4.20
x = 4.20 / 0.75
x = 5.6.....the maximum number of snacks he can buy is 5 <==
