Answer:
Step-by-step explanation:
The total number of students is 350 + 50 + 225 + 375 = 1000.
There are 225 students in band only, as well as 50 students in both band and choir. So there are 275 students in band out of the total of 1000, or 27.5%.
There are 350 students in choir only, as well as 50 students in both choir and band. So there are 400 students in choir, 50 of whom are also in band. So the probability is 50/400, or 12.5%.
The probabilities are not the same.
Since the probabilities are not the same, the probability of being in band is affected by whether or not the student is in choir. So the events are not independent.
The formula for the area of a trapezoid is
A = (1/2)(b₁ +b₂)h
Substitute the given information and evaluate. (Make sure all dimensions have the same units.)
A = (1/2)(12 ft +5 ft)(8 ft)
A = 68 ft²
The area of the trapezoid is 68 square feet.
Answer:
6 + (15) : 3 x (2) = 6 + 5 x 2 = 16

sixteen with Jaywhyypeeeee
I think (2,3) but I’m not completely sure
If dividing fractions
Don't be shy...
Just flip the second
And MULTIPLY!!!
They taught us this at school so it should be easier if you do this.
