Answer:
Step-by-step explanation:
we know that
The standard form of the quadratic equation is equal to
we have
eliminate the parenthesis
group terms that contain the same variable
combine like terms
The stem-and-leaf plot for the distribution is given as follows:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
b) From the plot, the correct options are given as follows:
- A typical content is 32 calories per 100 ml.
- The distribution is roughly symmetric.
<h3>What is a stem-and-leaf plot?</h3>
The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:
4|5 = 45.
For this problem, the observations are given at the top in red, and using each <u>first digit as the key</u>, the stem and leaf plot is:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
The mean of these observations is:
(19 + 2 x 22 + 23 + 25 + 2 x 27 + 2 x 28 + 30 + 2 x 31 + 32 + 2 x 33 + 34 + 3 x 35 + 37 + 38 + 39 + 2 x 40 + 41 + 43)/26 = 32(approximately)
The correct statements from the plot are as follows:
- A typical content is 32 calories per 100 ml(due to the mean).
- The distribution is roughly symmetric(13 values below the mean, 13 at or above).

Answer:
7+2+2
Step-by-step explanation:
Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
The next term is double the previous term, so that the -th term is given recursively by
This rule tells us that
and so on, with the explicit rule
for .
If 512 is the -th term in the sequence, then
