how am i meant to know if i cant see?
The two-way table shows the number of people who have or have not graduated from college and who live or do not live in their hometown.
Among people who do not live in their hometown, what is the relative frequency of not graduating from college? Express your answer as a decimal, and round to the nearest hundredth if necessary.
Live in their hometown Do not live in their hometown
Graduated from college 8 10
Didn’t graduate from college 6 4
Answer: 0.29
Step-by-step explanation:
From the given table, the number of people who do not live in their hometown=10+4=14
The number of people who have not graduated from college and do not live in their hometown= 4
Now, among people who do not live in their hometown, the relative frequency of not graduating from college
The answer is 1.
4x + 3x - 1 = 6
7x - 1 = 6 -Add the like terms
7x - 1 + 1 = 6 + 1 -Add 1 to both sides to 7x by itself
7x = 7
7x / 7 = 7 / 7 -Divide both sides by 7
x = 1
Hope I helped!
To put this into words, the equation is saying that one less than 4x + 3x is equal to 6.
First simplify by combining like terms. We see there is a 4x and 3x, which means that they are compatible with each other. The equation will then look like . If one less than 7x is 6, then this can also mean one more than 6 is equal to 7x. So add 1 to both sides:
--> , which means that x = 1.
Checking your work:
Now that we know the value of x, substitute that for x in the equation like this:
-->
--->
So you know it's true that x = 1. Hope this was helpful.

Answer:
y = 2x - 23 is the equation of the graph.
Step-by-step explanation:
The slope = (-7 - (-9) / ( 8 - 7)
= 2 / 1
= 2.
General form is y = mx + b
m = slope = 2 and the point (7, -9) lies on the line so:
-9 = 2(7) + b
b = -9 - 14 = -23.
So the equation of the graph is y = 2x - 23.
The volume of the triangular pyramid is 1980 cubic yards.
To find the volume of a triangular pyramid, we need to multiply the area of the base by the height and divide the result by 3. In this case, the base has an area of 330 square yards and the height is 18 yards.
So, the volume of the pyramid is given by:
Volume = (Base Area * Height) / 3
Plugging in the values, we get:
Volume = (330 * 18) / 3 = 1980 cubic yards.
