Answer:
Bc equals 17.
you must solve for BA and CA, because this is a isosceles triangle and isosceles have 2 equal sides.
BA = CA
then plug in what you find in for x
The answer is 60-5t<35-5t<_25t>5
Answer:
the answer is b
Step-by-step explanation:
got it right on the test
I believe this is D. The transitive property
To evaluate the given probability we proceed as follows:
The z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
from the question:
mean=272, sig=15
but the sample is n=36, thus we shall have:
√σ/n
=15/√36
=2.5
thus the z-score will be as follows:
x=272
z=(272-272)/2.5=0
x=274
z=(274-272)/2.5==0.8
thus
P(272<x<274)
=P(z<0.8)-P(z<0)
=0.7881-0.5
=0.2881
Hence the answer is 0.2881
