So first you have to do PEMDAS (Parenthesis, Exponent, Multiply, Divide, Add, Subtract). Now, when you do PEMDAS, you need to go from left to right in the order I just described to you.
So in this situation, first multiply 5 times 3 to get 15. Next is addition. 15+4=19.
PS sorry for taking so long.
Answer:
66.67% probability that all selected components function properly
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the components are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
Desired outcomes:
2 components which function properly, from a set of 5. So
Total outcomes:
2 components, from a set of 6. So
Probability:
66.67% probability that all selected components function properly
Ok, so what happend was 4 was added to every x, the whole thing was multiplied by -1 and -2 was added to the whole function
so
adding 4 to every x shifts the graph to the left 4 units
multiplying the whole function by -1 reflects it over the x axis
adding -2 to the whole function moves it down2 units
so that would be the first option
