Answer:
12.2 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
Here A = 20.74 and b = 3.4 , thus
× 3.4 × h = 20.74 ( multiply both sides by 2 to clear the fraction )
3.4h = 41.48 ( divide both sides by 3.4 )
h = 12.2 cm
Answer:
There is a 50.18% probability that they are of the same gender.
Step-by-step explanation:
We have these following percentages:
53% of the students are males.
47% of the students are females.
If two students from this college are selected at random, what is the probability that they are of the same gender?
The probability that each is male is 53%. So the probability of both being males is
The probability that each is female is 47%. So the probability of both being females is
The probabilty that both are the same gender is:
There is a 50.18% probability that they are of the same gender.
Answer:
hence cos ( 2 A ) = cos 2 A − ( 1 − cos 2 A ) = 2 cos 2 A − 1
Step-by-step explanation:Well we know that for two angles A , B
it holds that cos ( A + B ) = cos A cos B − sin A ⋅ sin B hence for A = B you get cos ( 2 A ) = cos 2 A − sin 2 A But sin 2 A = 1 − cos 2 A
a video game costs $3.50 a month. You're total cost is $31.50
Let video games = x
You're equation is:
31.50 = 3.50x
Solve for x. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Divide 3.50 from both sides
31.50/3.50 = 3.50x/3.50
x = 31.50/3.50
Divide
x = 9
9 is your answer
