53 + 44 = 97
180 - 97 = 83
Angle of B is 83 degrees
Answer:
pift^2(or your third option) is the area of a circle with a radius of 1.
DE would be congruent to QR
Hope this helps! ;)
Answer:
The lowest time limit in which 95% of the bugs can be found is 11.22 hours.
Step-by-step explanation:
We are given that X is the time in hours required to find a bug in a software system. Assume that X is normally distributed with mean of 3 and standard deviation of 5.
<em>So, X = time in hours required to find a bug in a software system </em>
X ~ N()
The z score probability distribution is given by;
Z = ~ N(0,1)
where, = mean value
= standard deviation
<em>Let the lowest time limit in which 95% of the bugs can be found = </em><em />
Now, we have to find the lowest time limit in which 95% of the bugs can be found, i.e.;
P( < ) = 0.95
P(Z < ) = 0.95
Now, the critical value of in the z table which given an area of less than 95% is 1.6449, which means;
= 1.6449
= 3 + 8.22 = 11.22
Therefore, the lowest time limit in which 95% of the bugs can be found is 11.22 hours.
Answer:
18 Milk Chocolates: 24 dark chocolates
Step-by-step explanation:
The total number of chocolates are 42
So you have Milk: Dark, in the ratio 3:4
You do 3+4 which = 7
You then divide the total ratio outcome by the total number
So you do, 42/7 =6
You then do 6 and put this into the ratio
So you do, 3x6 and 4x6, which = 18 and 24
To check if your answers correct add the ratio outcomes
And If you add 18 and 24 together, you should get your beginning total of 42
