To solve this problem, we must substitute in 1 for the variable x in the equation. This is because the function as written is f(x), meaning that the function is evaluated as x currently, but we want to evaluate it at 1. To do this, all we have to do is replace each variable x with a 1 and simplify.
f(x) = x^2 + 2x + 3
f(1) = (1)^2 + 2(1) + 3
To simplify, we first to compute the exponents. This is because of the order of operations, which says that we should solve parentheses first, exponents next, then multiplication/division, then addition/subtraction last.
f(1) = 1 + 2(1) + 3
Next, as outlined above, we should perform the multiplication.
f(1) = 1 + 2 + 3
Finally, we can finish solving by adding together the remaining terms.
f(1) = 6
Therefore, your answer is 6.
Hope this helps!
Answer:
A. Miguel has the greatest spread.
B. Considering the middle 50% of the training time, the person with the least spread is Adam.
C. Miguel is inconsistent with the time set for training compared to that of Adam.
Step-by-step explanation:
The spread of a data shows the range of the data.
Using the range to determine the spread of the given data:
A. The range of the two persons can be determined by:
Range = highest value - lowest value
So that:
Adam's range = 106 - 91
= 15
Miguel's range = 105 - 86
= 19
Comparing the range of the two, Miguel has the greatest spread.
B. Considering the middle 50% of the training time;
Adam - 103 105 104 106 100
Miguel - 88 86 89 93 105
Adam's 50% range = 106 - 100
= 6
Miguel's 50% range = 105 - 86
= 19
Considering the middle 50% of the training time, the person with the least spread is Adam.
C. The answers to parts 2(a) and 2(b) shows that; there is a wide variation (much inconsistency) in the time that Miguel spend during training, but a minimum variation in the time spent by Adam during training.
Well, if every item is divided into equal sets with no left over items I believe the correct answer is 60 children. Each set will contain 2 caps, 3 keychains and 4 bracelets with nothing left over. You can try other numbers but pretty sure you will still have things left over.
2x60 = 120
3x60 = 180
4x60 = 240
120/180/240
You would just add up all of the values and divide by six to get the average
