To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps
We need to simplify this number. We begin by evaluating the numbers inside the equation. We can simplify this to:
Now, we evaluate this one step further. Because a negative exponent makes the number 1 over what it was, we can make this problem:
This becomes:
So, 1/4k is the answer. This is the same as C, so C is the right answer.
I'm going to rewrite the equation assuming this is the correct form:
Answer:
$95
Step-by-step explanation:
I you need to see how much you would save after 7 weeks, and you save $10 a week, that would be 7*$10 and if you start with $25 you add it.
$25 + 7*($10) =
$25 + $70 = $95
After 7 weeks you would have saved $95.
If you need to know your savings each week, start with $25, and add $10 to it each week.
$25
Week 1 - $25 + 10 = $35
Week 2 - $35 + 10 = $45
Week 3 - $45 + 10 = $55
Week 4 - $55 + 10 = $65
Week 5 - $65 + 10 = $75
Week 6 - $75 + 10 = $85
Week 7 - $85 + 10 = $95
