Answer:
p = 43
Step-by-step explanation:
p + 7 + 3p + 1 = 180
4p + 8 = 180
4p = 172
p = 43

Step-by-step explanation:
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:
d
Step-by-step explanation:
f(x)-g(x)=2x²+4x-6-[2x²+2x+8]=2x²+4x-6-2x²-2x-8=2x-14
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- 4x + 8y = 20
- -4x + 2y = -30
<u>Adding</u><u> the</u><u> equations</u><u> </u><u>:</u><u>-</u><u> </u>
10y = -10
y = -1
<u>Put </u><u>it </u><u>(</u><u>i)</u><u> </u><u>:</u><u>-</u><u> </u>
4x - 8 = 20
4x = 20 + 8
4x = 28
x = 28/4
x = 7
