Answer:
In terms of probablity (A - appetizer oredered, B - desert ordered)
P(A)=63%
P(B)=40%
P(AorB)=76%.
Using the formula:
P(AorB)=P(A)+P(B)-P(A&B) we get P(A&B)=63%+40%-76%=27% (probability we were looking for).
When you are seeing which number is bigger first you look at the first digit
<u></u>0.<u>8</u>3 or 0.<u>8</u>02
^8 ^8
If they equal the same, look at the second digit
0.8<u>3</u> or 0.8<u>0</u>2
^3 ^0
3 is greater than 0
<u>0.83 is larger
</u>
you can also look at it this way:
0.83 = 0.830
What is bigger
0.802 or 0.830?
0.83 is bigger
The function that has a range limited to only negative numbers is Square Root.
<h3>Can one has the range of a function to be negative?</h3>
The function of this kind is known to be a kind of radical function that is said to have even index e.g. a square root. and thus, this radicand is one that can have a negative value for some or for the values of x.
Note therefore, that The function that has a range limited to only negative numbers is Square Root and thus it is correct.

<h3>
Answer: A = 43 degrees</h3>
Explanation:
The rule used here is
if sin(A) = cos(B), then A+B = 90.
In this case, B = 47, meaning that,
A+B = 90
A+47 = 90
A = 90-47
A = 43
Therefore,
sin(43) = cos(47)
Answer:
x = 15
Step-by-step explanation:
(2x + 20) + 130 = 180
2x + 150 = 180
- 150 - 150
2x = 30
/2 /2
x = 15
