The answer is C
Start by making two equations with the given information
The first would just be their total cans:
E + A = 257
The second would be:
5E - A = 13
Then combine the equations to eliminate one variable.
6E = 270
E = 45
Now plug E back into one of the equations.
45 + A = 257
A = 212

Answer: The highest score is 66
Step-by-step explanation: First we need to set the problem up.
x - 39 = 27
Next solve the problem.
Get x by itself by getting rid of the negative 39
x - 39 + 39 = 27 + 39
Add/Subtract
x = 66
You don’t need to simplify anymore so leave the problem alone since you already have the answer.
Hope it helped you guys!
Answer: 0.0136
Step-by-step explanation:
Let events are:
A = alarm A will fail
B= alarm B will fail
We have given ,
P(A) = 0.004 , P(B)=0.01
Since both events are independent , so
P(A and B) = P(A) x P(B)
= 0.04 x 0.01 =0.0004
i.e. P(A and B) =0.0004
Now , P(A or B) = P(A)+P(B)-P(A and B)
= 0.004+ 0.01-0.0004=0.0136
Hence, the probability that at least one alarm fails in the event of a fire is 0.0136 .
There is typo error in the question. The correct question is:
Solve for .
A.
B. 1
C.
D. 4
Answer:
A.
Step-by-step explanation:
Given:
The equation in 't' is given as:
In order to solve for we need to isolate 't'.
Multiplying both sides by 4, we get:
Now, dividing both sides by 3, we get:
Therefore, the value of is
