Answer:
Mean = 4.8875
Median = 4.6
Mode = 4.5 and 7.7
Step-by-step explanation:
Mean is the sum of total of data divided by the sample size
Sum total = 1.5 + 4.7 + 6 + 7.7 + 7.7 + 4.5 + 2.5 + 4.5
Sum total = 39.1
Sample size = 8
Mean = 39.1/8
Mean = 4.8875
To get the median we need to first rearrange
1.5, 2.5, 4.5, 4.5, 4.7, 6, 7.7, 7.7
Median = 4.5 + 4.7/2
Median = 4.6
Hence the median is 4.6
Mode is the value occuring the most. Since 4.5 and 7.7 both occurs twice, hence the mode of the data is 4.5 and 7.7
Answer:
The answer is 17.
Step-by-step explanation:
The answer is 17 because 17-3 = 14 and 14 times 3 = 42
Step-by-step explanation:
13x_6=9x+14
13x_9x=14+6
5x=20
x=20÷5
x=4
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12
