Answer:
The mean is: 85
Step-by-step explanation:
First you need to add everything up :
1 * 2 = 2
2 * 1 = 2
3 * 3 = 9
4 * 5 = 20
5 * 4 = 20
6 * 3 = 18
7 * 2 = 14
(I multiplyed them all first because i was fast than doing 4+4+4+4+4 because its the same as 4 * 5)
then add them all up 2+2+9+20+20+18+14=85
Answer:
The median is: 4
Step-by-step explanation:
Get the data in NUMERICAL ORDER (smallest to largest), then eliminate the extremes until we're at the middle. (basically chopping off the end till you get to the middle) Therfore The answer would be 4.
Answer:
The mode would be: 4
Step-by-step explanation:
The mode is Get the data in NUMERICAL ORDER, and see which value is the most frequent (we can have more than one mode).
Answer:
25%
Step-by-step explanation:
firs you do 5 divided by 20 because there are 20 x's. this will = 0.25
0.25 = 25%
I hope I get brainiest. Sorry for taking forever. Have a nice day!
Answer:
According to the first image, 1 cupcake costs $1.5.
So, we can use the rule of three to complete the table.
If 1 cupcake costs $1.5, 5 cupcakes would be $1.5(5)=$7.50
And 18 cupcakes would be $1.5(18)=$27.
However, $18 how many cupcakes represent?
Therefore, 12 cupcakes costs $18.
So, the table would be:
Cupcakes Prices
5 $7.50
12 $18
18 $27
Answer:
√a(√a + 2) a - 2√a
----------------- = -----------------
a - 4 a - 4
Step-by-step explanation:
I am assuming that by "sqrt(a)/sqrt(a)-2" you meant:
√a
----------
√a - 2
To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:
√a(√a + 2)
-----------------
a - 4
