Answer:
Angle x=19°
Angle Y=53°
I might be wrong though.
Step-by-step explanation:
Since a right angle is 90° and a straight line is 180°,the other side(71+x)=90.Therefore,90-71=19,which is angle x.
There is another straight line,since angle x is 19°.All you have to do is subtract 71+37+19 from 180 to get Angle Y.The answer is 53°.
Angle X=90-71=19
Angle Y=180-37-71-19=53.
Answer: 482
Step-by-step explanation:
Formula to find the sample size is given by :-
(1)
, where z* = critical z-value (two tailed).
= Population standard deviation and E = Margin of error.
As per given , we have
Margin of error : E= 3
Confidence level = 90%
Significance level =
Using z-table , the critical value for 90% confidence=
Required minimum sample size = [Substitute the values in formula (1)]
[ Round to the next integer]
Hence, the number of observations required is closest to 482.
6.91, 7, 7 1/8, 15/2 OR 7 1/2
6.91 would be the least due to the whole number (6) being already less than 7. Next is 7 because of it being by itself with no fraction added. Next is 7 1/8 and 15/2. 15/2 is greater than 7 1/8 because when simplified you get 7 1/2 which can become 7 4/8, therefore greater than 7 1/8.

Example: f(x) = 2x+3 and g(x) = x2
"x" is just a placeholder. To avoid confusion let's just call it "input":
f(input) = 2(input)+3
g(input) = (input)2
Let's start:
(g º f)(x) = g(f(x))
First we apply f, then apply g to that result:
Function Composition
- (g º f)(x) = (2x+3)2
What if we reverse the order of f and g?
(f º g)(x) = f(g(x))
First we apply g, then apply f to that result:
Function Composition
- (f º g)(x) = 2x2+3
We get a different result! When we reverse the order the result is rarely the same. So be careful which function comes first.

1. P(getting all head)=
2. Event: getting all head can happen in only one way: HHH
3. n(Sample space) can be calculated by
a. counting, a good ways to organize counting is drawing a tree diagram, CHECK THE PICTURE
or
b. There are 2 possible outcomes each time we throw the dice so 2*2*2=8 is the total number of outcomes, that is the number of the sample space.
4. So finally P(getting all head)=
