Answer: 45
Step-by-step explanation:
Given: The total number of lettered tiles in a board game =105
The number of tiles chosen (R, A, I, L, M, B, E) = 7
the number of vowels chosen (A,I,E)=3
Now, the fraction or probability of choosing of vowels out of 7 given letters is given by :-
Now, the number of vowels we can expect to be vowels out of 105 letters is given by :-
Hence, the number of vowels we can expect to be vowels out of 105 letters is 45.
Answer: 0
Step-by-step explanation: Two of the numbers are both negative you’re going to want to add those together first. -17 + (-3) = -20. What’s left is -20 + 20 when you add a positive (20) with a negative (-20) you’re going to need to ‘subtract’ so sort of like this : 20 - 20 and that equals 0

The required, any triangle that has two sides and the included angle between them given can have its area calculated using the trigonometricarea formula.
The triangle is a geometricshape that includes 3 sides and the sum of the interior angle should not be greater than 180°
The trigonometric area formula can be used to calculate the area of a triangle when we know the lengths of two sides and the included angle between them. The formula is:
Area = 1/2 * a * b * sin(C)
where a and b are the lengths of the two sides, and C is the angle between them.
Therefore, if we are given the lengths of two sides and the angle between them, we can use the trigonometric area formula to calculate the area of the triangle. This formula is particularly useful when we do not know the height of the triangle or cannot easily calculate it using other methods.
So, any triangle that has two sides and the included angle between them given can have its area calculated using the trigonometric area formula.
