Answer:
1/4
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations
= 5/20
To transform to the simplest form. divide both the numerator and the denominator by 5
= 1/4
Answer:
Step-by-step explanation:
The absolute difference is 77-(-8)=85. The only option that is equivalent is
|-8|+77
Answer:
Step-by-step explanation:
To solve an equation for one of its variables do that:
- Underline the variable
- Separate it one side and the other terms on the other side
- Make its coefficient equal to 1
Let us use these steps to solve our question
∵ V = πr²h
→ Underline r²
∴ V = π<u>r²</u>h
→ Take π and h to the other side by dividing both sides by πh
∵ 
∴ 
→ The coefficient of r² is 1, so switch the two sides
∴
A rotation transformation is where you turn a figure about a given point. The point about which the object is rotated can be inside the figure or anywhere outside it. There must be no change in shape or size of the object.
A reflection of an object is the 'flip' of that object over a line, called the line of reflection.
A translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized.
All these three transformations are rigid - preserve the figure sizes.
A dilation is a transformation that changes the size of a figure. It can become larger or smaller, but the shape of the figure does not change.
Answer: dilation maps the large triangle onto the small triangle
When you have f(3), that means X is equal to 3.
The problem states if x <-3 then f(x) would be -2.
If x is between -1 and -3, then f(x) would be 4x.
If x is greater than -1, f(x) would be x^2.
3 is greater then -1, so f(3) would be x^2, now replace x with 3 to get 3^2, which equals 9.
f(3) = 9
