Answer:
7 ; 2 ; 8
Step-by-step explanation:
money for raffle= 350 pounds
money for quiz=14 multiplied by 4= 56
56+44= 100
money for membership fees= 20 multiplied by 20= 400
Ratio
Raffle :Quiz: Membership fees
350 : 100 : 400
35 : 10 : 40 (divided by 10)
7 : 2 : 8 (divided by 5)
it can not be simplified further
A+b=6.1 ---(1)
a-b=1.6 ---(2)
(1)+(2); 2a=7.7
then a=3.85
so b=a-1.6 = 3.85-1.6 = 2.25
so that the two numbers are 2.25 and 3.85
Using the regression formula with a slope = 2000 and intercept = 15000, what would the predicted income be for someone who has 16 years of education.
The answer is (D) or 1728 In³
The solutions of the equation are -12 and 16
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then
∵ 2Ix - 2I - 8 = 20
- At first add 8 to both sides
∴ 2Ix - 2I = 28
- Then divide both sides by 2
∴ Ix - 2I = 14
Now By using the notes above equate x - 2 by 14 and -14
∵ x - 2 = 14
- Add 2 to both sides
∴ x = 16
∵ x - 2 = -14
- Add 2 to both sides
∴ x = -12
The solutions of the equation are -12 and 16
