find the mean, median, and mode of the data set. round to the nearest tenth. 7,7,14,15,4,1,7,2,15,9,5
Arisa [49]
Here is the mean, median, and mode:
Mean: 1+2+4+5+7+7+7+9+14+15+15 = 86/11 ≈ 7.82
Median: 7
Mode: 7
To find the mean add up all the numbers and divide by the number of numbers
To find the median you just keep on crossing of numbers left to right until you get the middle number
To find the mode just look at which number is most commonly seen
Hope this helps!
I would choose the answer D
angle AOB = 132 and is also the sum of angles AOD and
DOB. Hence
angle AOD + angle DOB = 132° ---> 1
angle COD = 141 and is also the sum of angles COB and BOD. Hence
angle COB + angle DOB = 141° ---> 2
Now we add the left sides together and the right sides of equations 1 and 2
together to form a new equation.
angle AOD + angle DOB + angle COB + angle DOB = 132 + 141 ---> 3
We should also note that:
angle AOD + angle DOB + angle COB = 180°
Therefore substituting angle AOD + angle DOB + angle COB in equation 3 by 180
and solving for angle DOB:
180 + angle DOB = 132 + 141
angle DOB = 273 - 180 = 93°
Value of x is 2.
Step-by-step explanation:
- Step 1: Given that x+1/3 = x/2
Cross-multiply to find the value of x.
⇒ 2(x + 1) = 3x
⇒ 2x + 2 = 3x
⇒ x = 2
Subtract $7.08 from $166.30 = $159.22
