The second graph is correct
Q1.
Angle BAD is adjacent to angle CAD
which means they are equal
so angle BAD = 26 degrees
Q2.
Angel BAC = the sum of angles BAD and CAD
because they are adjacent angles
To find the angles we solve the equations
9x-5 = 3x+7
9x-3x = 7+5
6x = 12
x = 12/6
x = 6
<u>During the first hour</u> . . .
5% of the 1,000 bacteria die. At the end of the hour, 95% of them are left.
95% of 1,000 = 950
Then 100 are added : 950 + 100 = 1,050
<em>1,050</em> bacteria swimming around in the soup as the second hour begins.
<u>During the second hour</u> . . .
5% of the 1,050 bacteria die. At the end of the hour, 95% of them are left.
95% of 1,050 = 997.5
Then 100 are added : 997.5 + 100 = 1,097.5 . . . . . <em>1,098</em> rounded
===================================
<u>Playing with this some more</u>:
If the same process continues, and the result at the end of each hour
is rounded to the nearest whole number, then the number of bacteria
steadily increases, but only for 88 hours. At the end of the 88th hour,
there are 1991 of the little critters, and after that, the population stays
constant at 1991. That's because the 5% loss during each hour after
that is (5% of 1,991) = 99.55 , which rounds to 100, and those are
replaced by the 100 new ones.
Answer:

Step-by-step explanation:
Given

Required [This completes the question]
The probability of exactly 0 deaths
This probability follows a Poisson distribution, and it is given by:

For 0 deaths;

So, the expression becomes




Substitute 0.011 for 


<em>The probability of having exactly death is 0.9891</em>
Answer:
1. 2:5
2. 110 (the total degree of a triangle is 180 so it would be 40+30+x=180)
3. 37 (It's a right angle, 90 degrees so it would be 90-53=x)
