Answer:
2/10 or 1/5
Step-by-step explanation:
there are 10 equal 'slices'
then count those with a J
that would be 2
The mean, since it's the average of whatever your data is.
The mean is often the default measure of center because it includes every data point, ie its more representative. However, if you have outliers then the mean will be skewed toward the outlier. For example, with home prices, very expensive houses will make the mean larger than it should be if you focused on the main cluster of data. This is why the median home price is often measured and reported (rather than the mean home price).
Answer:
The 3rd choice: 2/3 tank - 1/6 tank = 1/2 tank
Step-by-step explanation:
I assume those numbers are fractions.
The gas tank of Wendy’s car was 2/3 full. She used 1/6 of a tank of gas when driving to and from work. Which equation shows how full the gas tank is now?
We subtract 1/6 from 2/3. We need to use the common denominator 6.
2/3 - 1/6 = 4/6 - 1/6 = 3/6
Now we reduce 3/6.
2/3 - 1/6 = 1/2
Answer: 2/3 tank - 1/6 tank = 1/2 tank
(4x + 7)² = 60
(4x + 7)(4x + 7) = 60
(4x² + 28x + 28x + 49) = 60
4x² + 56x + 49 = 60
<u> -49 -49</u>
4x² + 56x = 11
4x² + 56x - 11 = 11 - 11
4x² + 56x - 11 = 0
x = <u>-56 +/- √(56² - 4(4)(-11))</u>
2(4)
x = <u>-56 +/- √(3136 + 88)</u>
8
x = <u>-56 +/- √(3174)</u>
8
x = <u>-56 +/- 56.34</u>
8
x = -7 +/- 7.0425
x = -7 + 7.70425 x = -7 - 7.70425
x = 0.70425 x = -14.70425
