find the mean, range ,and median of these values 12,4,-2,0,9.-2,1,7,8,2 recall the range is calculated by finding the difference
Lubov Fominskaja [6]
Put numbers in order
-2,-2,0,1,2,4,7,8,9,12
Mean add all the numbers = 39 divide 39 by the number of of numbers on the list which is 10. 39/10 = 3.9
Mean = 3.9
Range is the number of spots between -2 and 12 = 14
Range =14
Median is the middle number in the list there are two middle numbers 2 and 4. Add these together to get 6. Divide 6 by the number 2 because that is how many numbers you had to add. 6/2=3. The is not on the list but it is the average of the two terms.
Median =3
Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x.
x+x+5+4x=137
Combine like terms
6x+5=137
Subtract 5 from both sides
6x=132
Divide by 6 on both sides
x=22
First:
22 calls
Second:
x+5
22+5
27 calls
Third:
4x
4*22
88 calls
Hope this helps!
Answer:
- 20
Step-by-step explanation:
Given that,
Flavors of tea = 5
Types of packaging = 2
So,
No. of possibilities = 5 * 2
= 10
A.T.Q.,
4 from 5 total flavors will be included in the variety pack, the number of available choices = 5C4
= 5 choices
Since 5 choices are probable for each form, The total in two forms would be 5 * 2 = 10.
Therefore,
Total no. of different packs can be possible = 10 + 10
= 20
We know that
<span>a) Paula’s recipe calls for 8 ounces of oil for every 3 ounces of vinegar
ratio </span><span>of vinegar to oil-----> 3 ounces/8 ounces-----> 0.375
</span>
b) <span>Carlo’s recipe has 1 ounce of vinegar for every 4 ounces of oil
</span>ratio of vinegar to oil-----> 1 ounces/4 ounces---> 0.25
1) <span>Whose recipe has a smaller ratio of vinegar to oil?
0.25< 0.375
so
</span>Carlo’s recipe < Paula’s recipe
<span>
the answer Part 1) is
</span>Carlo’s recipe has a smaller ratio of vinegar to oil--- > 0.25
Part 2) <span>Paula’s dressing ratio of vinegar to oil written as a fraction is 3/8
Part 3)</span><span>Carlo’s dressing ratio of vinegar to oil written as a fraction is 1/4 (is equal to 2/8)
</span>
Part 4) <span>A common denominator for these fractions is 8</span>
