Using the mean of the data-set, it is found that the missing height in the stem-and-leaf plot is given by:
D. 65 in.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, following the key of the stem-and-left plot, there are 8 observations, given as follows:
54, 55, 56, 61, 63, 64, 70 and the missing value x.
The mean is of 61, hence:
423 + x = 61 x 8
x = 65.
Hence option D is correct.

The events are not independent.
The probability of selecting a football card and a basketball card is 0.16.
<h3>What is the probability?</h3>
Probability is the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of selecting a football card and a basketball card = (number of football cards / total number of cards) x (number of basketball cards / total number of cards)
2/10 x 8/10 = 0.16

Answer:
It's a rational number
Step-by-step explanation:
Hope this help have a good day and good luck plz vote best answer :)
Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
= 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
= 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
= 9138.44 dollars
<span>$9,138.44</span> is the correct option in regards to the question given.
Compound Interest Formula:
A = P(1 + r/n)^(nt)
A= Accumulated amount with interest P= principal= $1000
R= annual interest rate (decimal)= 0.05
N= # times compounded per year= 12
T= # of years= 10
A= 1000(1 + 0.05/12)^(12*10)
divide inside parentheses first
A= 1000(1 + 0.0041666667)^ (12*10)
add inside parentheses
A= 1000(1.0041666667)^ (12*10)
multiply exponents
A= 1000(1.0041666667)^120
multiply parentheses by exponents
A= 1000(1.6470095043)
multiply last two numbers
A= $1,647.01 amount after 10 years
ANSWER:
D) $1647.01 total after 10 years
Hope this helps! :)
