Answer:
i think its 1/10 or 1 over 10
Step-by-step explanation:
y is part of a right angle on line AB
a right angle = 90 degrees
90-47 = 43 degrees
y = 43 degrees
a straight line = 180 degrees
180-47 = 133 degrees
x = 133 degrees
Answer:
factorize form of the equation is
, where 
Step-by-step explanation:
Given Equation:
Adding the terms of 'x' and taking constants on the other side.

The sign of the constant will change on changing the side of it.



So, the value of 'x' is 1
The factorized form of the equation can be made by taking the common value from the equation i.e


They can not, there are only 2 sides and they probably flipped it different ways. They got 'lucky'.
Answer:
we reject H₀
Step-by-step explanation: Se annex
The test is one tail-test (greater than)
Using α = 0,05 (critical value ) from z- table we get
z(c) = 1,64
And Test hypothesis is:
H₀ Null hypothesis μ = μ₀
Hₐ Alternate hypothesis μ > μ₀
Which we need to compare with z(s) = 2,19 (from problem statement)
The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region
So base on our drawing we will reject H₀
