Step-by-step explanation:
12n-17=0
12n=17
n=17/12
1, 1, 1, 1, 4, 7, 7
Median (middle) = 1
Mode (most common) = 1
Range (largest# minus smallest#) = 6
5, 10, 10, 15, 15, 15, 20
Median = 15
Mode = 15
Range = 15
Answer:
1200
Step-by-step explanation:
n = 0.08 r + 7400
n = 7496, r = ?
7496 = 0.08r + 7400
7496 - 7400 = 0.08r
96 = 0.08r
r = 96/0.08
r = 1200
Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The coins are in the ratio 2:5:7 respectively. If he has a R90 in R2 coins. If x represent the total coins, hence:
(5/14) * x = 90
x = 252
Number of R5 coins = (2/14) * 252 = 36
Number of R1 coins = (7/14) * 252 = 126
Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins,
