Let's first find the mode of each data set.
Mode = the largest value - the smallest value.
A. 20 - 11 = 9
B. 31 - 5 = 26
C. 20 - 11 = 9
D. 15 - 6 = 9
B fails because its mode does not equal 9.
Let's find the mean of A, C, and D
The mean = the sum of all data values divided by the number of data values.
A. (11 + 11 + 13 + 15 + 20) / 5 = 14.2
C. (11 + 11 + 14 + 19 + 20) / 5 = 15
D. (6 + 10 + 14 + 15 + 15) / 5 = 12
Options A and D fail because their mean does not equal 15.
Let's find the median and mode of option C
Median = the value which falls into the middle of our data set
11, 11, 14, 19, 20 = 14
Mode = the value which appears most often
In option C, 11 appears twice and every other number appears once, therefore, 11 is the mode.
Answer:D) y = 2/3x
Step-by-step explanation: Sketching the triangles shows that ΔABC has a coordinate of C = (6, 4)
m =
change in y
change in x
=
4 − 2
6 − 3
=
2
3
therefore, y =
2
3
x
Answer:
<u>$1,159.69</u>
Step-by-step explanation:
Compound Interest Formula :
- A = amount
- P = principal
- r = rate (in decimals)
- n = number of times compounded
- t = number of years
Solving :
- A = (1,000)(1 + 0.05/2)²⁽³⁾
- A = (1,000)(1.025)⁶
- A = (1,000)(1.15969342)
- A = <u>$1,159.69</u>
I'll try to understand this but I don't really get it because I'm in middle school
