Answer:
Given: and
.
Prove:
Since , By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly
, it means angles 5, 6, 7 and 8 are 90 degree.
We can say that,
,
,
and
From figure it is noticed that the angle 1 and 5 are corresponding angles.
If two parallel lines are intersected by a transversal, then the corresponding angles are equal.
Since corresponding angles are congruent, therefore the line must be parallel to each other.
Hence proved that .
Answer:
A
The correct option is B
B
C
D
The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size is
The number that developed nausea is X = 50
The population proportion is p = 0.20
The null hypothesis is
The alternative hypothesis is
Generally the sample proportion is mathematically represented as
Generally the test statistics is mathematically represented as
=>
=>
=>
The p-value obtained from the z-table is
Given that the then we fail to reject the null hypothesis
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Which steps would you use to solve this equation? p+7=12
We can solve this equation in one step only, and this is the step:-
Subtract 7 from both sides
p=12-7
p=5
