The answer is D. -15 because I am assuming that the vertical lines mean brackets, and we have to work out the brackets first (according to BIDMAS). Doing so, -6 + 2 = -4 and -4 + -11 = -15.
Answer:
the hypotenuse is the bigger one
Step-by-step explanation:
Right?
Let the total amount of pages be t
t=30+1/8t+2/8t
now simplify
t=30+3/8t
5/8t=30
divide 30 by 5
1/8=6
now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
Answer:
Probability = 0.275
Step-by-step explanation:
There are two possible ways for his design to be approved: Being a high-energy engine (H) and being approved or a low-energy energy (L) and being approved.
It is known that there is a 50-50 chance of the engine being high or low-energy.
The probability of approval for each type of engine (E) is given by:

Where A(E) is the approval rate for each engine.
Therefore, the probabilities of approval for each type of engine are:

The total probability of approval is the sum of both low and high-engine probabilities;

The answer to this problem is 6 11/40
