Answer:
Step-by-step explanation:
Given
The attached graph
Required
Determine the range of the graph
First, we list out the coordinate of each point on the graph:
The points are:
A function has the form: (x,y)
Where
y = range:
From the coordinate points above,
Order from least to greatest"
Hence, the range are:
Answer:
There will be 4 blue marbles
Step-by-step explanation:
Yellow to blue marbles is in a ratio of:
5:10
the representative sample is:
2:x
simplee cross multiplication can be aplied
5x = 2*10
5x = 20
divide both sides by 5
x = 4
there should be four blue marbles
Answer:
There are 9 boys in the choir
Step-by-step explanation:
To solve this, create two equivalent fractions with the information given
boys 3 x
------- = ------ = ------
girls 4 12
Then, cross-multiply
4x = 3(12)
4x = 36
x = 9
X - 13 < ( with a line under the symbol) 39
another term x - 13 < or = to 39
