Answer:
x=20
y=10
Step-by-step explanation:
so as you can see this is a 30-60-90 triangle this means that y is opposite the 30 degree angle so it is 10 root three divided by root three so it is ten and x is 2y=20
Answer:
I’m hoping you mean ratio, 1:9
Step-by-step explanation:
2. Because it is being reflected across the X axis, the X coordinate would change signs, but the Y coordinate would remain the same sign.
A(-6,-4) would become A'(6,-4)
B(-3,5) would become B'(3,5)
C(1,-1) would become C'(-1,-1)
The answer would be the third choice.
3. Reflected across the Y axis, the X would stay the same sign and the Y would change signs.
P(-2,-4) would become P'(-2,4)
Q(2,-5) would become Q'(2,5)
R(-1,-8) would become R'(-1,8)
The answer would be the second choice.
Answer:

A. n and k are on plane A and s
C. p is the inteersection of n and g
D. those 3 lines are noncollinear
Answer:
Option A 0.312 is right
Step-by-step explanation:
Given that iN Maplewood a certain type of DVD player is sold at just two stores, 43% of the sales 13) are from store A and 57% of the sales are from store B. 2.4% of the DVD players sold at store A are defective while 4.0% of the DVD players sold at store B are defective.
Prob for any random item form store to be defective = Prob from A and defective +Prob from B and defective
=
Prob it came from A and defective = 0.
If Kate receives one of these DVD players as a gift and finds that it is defective, what is the probability that it came from store A
=
