Answer:
P(number greater than 3) = 
Step-by-step explanation:
The Probability of getting a number greater than 3 means the possibility of getting 4 or 5 or 6
That is
P(number greater than 3) = P(getting 4) + P(getting 5) + P(getting 6)
On substituting the values from the table ,
we get
P(number greater than 3) = 
P(number greater than 3) =
Thus if the number cube is tossed once, P(number greater than 3) is
Answer:
3x^5 -2x^4 -x^2 +x -21
Step-by-step explanation:
We need to subtract g(x) from f(x)
f(x) = 3x^5 +6x^2 -5
g(x) = 2x^4 +7x^2 -x+16
f(x) -g(x) = 3x^5 +6x^2 -5 - (2x^4 +7x^2 -x+16)
Distribute the minus sign
3x^5 +6x^2 -5 - 2x^4 -7x^2 +x-16
I like to line them up vertically
3x^5 +6x^2 -5
- 2x^4 -7x^2 +x-16

Answer:
I think Leslie Is 20
Step-by-step explanation:
Answer:
3ft:1in
Step-by-step explanation:
Given the clay model of a new car = 7in
If the actual car is 21ft, first we will have to convert 21ft to inches
Ift = 12in
21ft = x
x = 21×12.
x = 252in
21ft = 252in
This means that the clay model (7in) has to be scaled up to 252in. This is known as enlargement.
To know the scale of the model, we will take the ratio of the actual car to the clay as shown
Scale = actual car model/clay car model
Scale = 252/7
Scale = 36/1
We can also use the exact units of both measurement used in question
Scale = 21ft/7in
Scale = 3ft/1in
Hence the scale of the model is 3ft:1in
Answer:
x = 10
Step-by-step explanation:
note that sin30° = 
Since the triangle is right use the sine ratio to find x
sin30° = 
= 
multiply both sides by x
x × = 5 ( multiply both sides by 2 )
x = 10
