Answer:
In a histogram, the distribution of the data is symmetric if it has one prominent peak and equal tails to the left and the right. The Median and the Mean of a symmetric dataset are similar.
Step-by-step explanation:
“Y” is equal to 9 because you substitute the x which is 2 and then solve from there
Answer:
Step-by-step explanation:
(x - 8)*5 = 70
5x - 40 = 70
5x - 40 + 40 = 70 + 40
5x = 110
x = 110/5
x = 23
She started with 23
So You should have done
23 - 5 = 18
18 * 8 = 144
What you should have obtained was 144
Answer:
d
Step-by-step explanation:
Solution by substitution method
y=7x+8
∴y-7x=8
and y=x+20
∴y-x=20
Suppose,
-7x+y=8→(1)
and -x+y=20→(2)
Taking equation (1), we have
-7x+y=8
⇒y=7x+8→(3)
Putting y=7x+8 in equation (2), we get
-x + 7x + 8 = 20
6x = 20-8
6x = 12
x= 12 / 6
x = 2
substitute for x in equation (3)
y = 7(x) + 8
y = 7(2) + 8
y = 22
Let V = volume of the container.
Translate English to math (equation):
(1/4)V + 9 = (5/8)V
Multiply by 8
2v + 72 = 5V
Subtract 2V from each side
3V = 72
V = 24
The container can hold 24 gallons of water.
