Answer:
The expected value of a fair game should be >0
Thus the answer is (c)
Answer:
The value of sine of angle XYZ is equal to 0.96.
Step-by-step explanation:
Given that,
Base, b = 4 cm
Height, h = 13 cm
We need to find the sinY.
Using Pythagoras theorem,
YZ² = XY² + XZ²
YZ² = 4² + 13²
YZ = 13.60 cm
Using trigonometry,
So, the value of sine of angle XYZ is equal to 0.96.
To concert a percentage into a fraction, first convert it into a decimal.
To change a percentage into a decimal, you have to take away the percentage sign and move the decimal point two places to the left.
Thus, 40% = 0.40 = 0.4
Now, to change the decimal into a fraction, you multiply both the numerator and the denominator (1) by 10.
0.4/1 = 4/10
However, in this case the fraction is in simplest form. To simplify a fraction, you have to divide the numerator and the denominator by the GCF, which in this case is 2.
4/10 = 2/5
Therefore, your answer is D. 2/5 off.
We have to choose two points of this graph:
A(5,0)
B(0,-4)
And we have to compute the slope:
Given two points A(x₁,y₁) and B(x₂,y₂) the slope between these points would be:
m= slope
m=(y₂-y₁)/(x₂-x₁)
In this case:
m=(-4-0)/(0-5)=-4/(-5)=4/5
Answer: the slope would be 4/5 and all of these answer would be wrong.
The relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.
<h3>What are complementary angles?</h3>
The angles when added give the sum of 90 degrees and are called complementary angles. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
In the given figure it is observed that the two angles ∠a and ∠b when added give 90 degrees.
Therefore, the relation between the two angles ∠a and ∠b is that they are complementary angles. The correct option is B.
