Answer:
.
Step-by-step explanation:
This triangle is a 30-60-90 triangle. That means that the hypotenuse is double the length of the smaller side.
Since the smaller side measures , the hypotenuse is .
Hope this helps!
Answer:
The product of a+3 and -2a2+15a+6b2. O-2a3+9a2+r5a+24b2
Answer:
y = 1/4x - 19/4
Step-by-step explanation:
Use the equation y = mx +b
x (x coordinate) = -1
y (y coordinate) = -5
slope (m) = 1/4
Plug in!
-5 = 1/4(-1) + b
-5 = -1/4 + b
-5 + 1/4 = b (Add 1/4 to both sides)
-20/4 + 1/4 = b
-19/4 = b
y = 1/4x - 19/4

The probability that a freshman student at this school plays either a sport or a musical instrument is 0.74
Step-by-step explanation:
The addition rules in probability are:
- P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)
- P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)
∵ The probability that a freshman plays a sport is 0.55
∴ P(sport) = 0.55
∵ The probability that a freshman plays a musical instrument is 0.34
∴ P(music) = 0.34
∵ The probability that a freshman plays both a sport and a musical
instrument is 0.15
∴ P(sport and music) = 0.15
To find the probability that freshman student at this school plays either a sport or a musical instrument use the second rule above because it is non-mutually exclusive
∵ P(sport or music) = P(sport) + P(music) - P(sport and music)
∴ P(sport or music) = 0.55 + 0.34 - 0.15
∴ P(sport or music) = 0.74
The probability that a freshman student at this school plays either a sport or a musical instrument is 0.74
