Answer:
<em>75</em>
Step-by-step explanation:
Subtracting a number means adding the opposite.
The opposite of a number is the number you obtain by just changing the sign.
The opposite of 5 is -5. The opposite of 100 is -100. The opposite of -4.5 is 4.5. The opposite of 0 is 0. Zero is the only number that is equal to its opposite.
You need to subtract -45, so add the opposite of -45 which is 45.
30 - (-45) = 30 + 45 = 75

Answer:
D. $701.50
Step-by-step explanation:
Since we are rounding to the nearest tenth decimal, look in the hundredths place for the number to round up or down with. In this case, it is 9. That means the tenths place would round up to 5.
F(-4)= 9*3^(-4)=9/(3^4)=1/9
Answer:
Part A:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B: Brand Y has a longer battery life
Step-by-step explanation:
Part A:
Median value is depicted on a box plot by the vertical line that divides the rectangular box. Therefore:
Median value for Brand X = 13
Median value for Brand Y = 16
Part B:
Brand Y has a higher median value (16) than Brand X (13).
This implies that brand Y has a battery life that last longer than brand X.
