Answer:
1/4
Step-by-step explanation:
Let x = number the spinner lands on
P(X = 1) = 1/4
P(X = 2) = 1/4
P(X = 3) = 1/4
P(X = 4) = 1/4
The spins are independent events as their probabilities are not affected by whether or not the other event happens
Therefore, the probability that you land on a number 2 given that your first spin landed on number 1 is still 1/4

From the diagram you can see that we have constructed a right triangle, with height A and base 15.
Length of shadow = 15 feet.
Height of flagpole = A.
We know the angle of elevation is
40
∘
. Using this angle and the tangent ratio, we can find A.

Answer:
Step-by-step explanation:
In order to find the values to factorize the equation, we need to find the factors the factors of 3 that sum to 4
The factors of 3 are
We can make 4 with 1 + 3
Since all the values are positive, both of the factors will have addition
