Answer:
Just put 4 basketballs and 5 baseballs in each one
Step-by-step explanation:
If you think about it you will know that each ratio there is the same. So, you do the same thing each time.
All you have to do now is read. It says put 4 basketballs and 5 baseballs.
I hope this helped ;)
The probability that student scored more than 850 we shall proceed as follows:
z=(x-μ)/σ
where:
x=850
μ=750
σ=50
thus
z=(850-750)/50
z=2
thus
P(x>850)=1-P(x<850)=1-P(z<2)=1-0.9772=0.0228
Answer: P(x>850)=0.0228
Step-by-step explanation:

Answer: Choice A

Explanation:
Recall that 
and 
. The connection between tangent and cotangent is simply involving the reciprocal
From this, we can say,
In the second to last step, a pair of sine terms cancel. In the last step, a pair of cosine terms cancel.
All of this shows why is identical to 
Therefore, 
is an identity. In mathematics, an identity is when both sides are the same thing for any allowed input in the domain.
You can visually confirm that is the same as by graphing each function (use x instead of alpha). You should note that both curves use the exact same set of points to form them. In other words, one curve is perfectly on top of the other. I recommend making the curves different colors so you can distinguish them a bit better.
Answer:
x=15º
Step-by-step explanation:
180=25+8x+5+2x
180=30+10x
180-30=10x
150=10x
15=x
