Addition: -1 + -3 = -4
Subtraction: (-4) - 5 = -10
Step-by-step explanation:
Since adding a positive makes a negative number stay negative, it equals -4.
Then by subtracting a negative with a positive (5), the number stays negative once again, which then equals -10.

A sample of a radioactive isotope had an initial mass of 690 mg in the
year 1997 and decays exponentially over time. A measurement in the
year 2001 found that the sample's mass had decayed to 390 mg. What
would be the expected mass of the sample in the year 2011, to the
nearest whole number?
Answers
Answer:
its 94 on deltamath just did it
Step-by-step explanation:
Let t=0 represent the year 1997
Starting Value: 690
Write function:
y=690(b)^t
Now find the b-value:
y=390 when t=4 (2001−1997)
390=690(b)^4
390/690=690(b)^4/690
0.56521739=b^4
(0.56521739)^1/4=(b^4)^1/4
0.86706944=b
Write Complete Function:
y=690(0.86706944)^t
Find value in 2011 (use t=14):
y=690(0.86706944)^14
y=93.67062063
y≈94

Jillian and Sammi sell 3 pillows for $3.20 each. Then they share the money equally. How much money does each girl get?
Answers
Answer:
$4.8
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Price of each pillow = $3.20
Total number of pillows = 3
So, total amount after selling = Price of each pillow × Total number of pillows
= $3.20 × 3
= $9.60
Total number of girls = 2
So, Money each girl gets = total amount after selling ÷ Total number of girls
= $9.60 ÷ 2
= $4.8

A sampling method where you determine randomly where you want to start selecting in the sampling frame and then follow a rule to select every xth element in the sampling frame list is called a ____ method.
Answers
Answer:
Systematic
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Every xth element, so systematic.
What is the strongest classification of the figure formed by the following points?

OA. Paralellogram
OB. Quadrilateral
OC. Rectangle
OD. Rhombus
Answers
Answer:
A. Parallelogram
Step-by-step explanation:
The given points are;
(-10, -4), (-7, -8), (-5, -4), (-2, -8)
Let 'A' represent the point (-10, -4), let 'B' represent the point (-7, -8), let 'C' represent the point (-5, -4), and let 'D' represent the point (-2, -8), we have;
The (horizontal) distance between points A and C = -5 - (-10) = 5
The (horizontal) distance between points B and D = -2 - (-7) = 5
Therefore;
The length of [tex]\overline {AC}[/tex] = The length of [tex]\overline {BD}[/tex]
The length of [tex]\overline {AB}[/tex] = √((-10 - (-7))² + (-4 - (-8))²)) = 5
The length of [tex]\overline {CD}[/tex] = √((-5 - (-2))² + (-4 - (-8))²)) = 5
∴ The length of [tex]\overline {AB}[/tex] = The length of [tex]\overline {CD}[/tex]
[tex]\overline {AC}[/tex] is parallel to the horizontal axis
[tex]\overline {BD}[/tex] is parallel to the horizontal axis
∴ [tex]\overline {AC}[/tex] ║ [tex]\overline {BD}[/tex]
Given that [tex]\overline {AB}[/tex] = [tex]\overline {CD}[/tex], then [tex]\overline {AB}[/tex] ║ [tex]\overline {CD}[/tex]
Therefore, the quadrilateral ABCD is a parallelogram
(The angle ∠ABD = 180 - arctan (4/3) ≈ 126.9 > 90, therefore, the parallelogram ABCD is not a rectangle.)

What is a statistical question and what is its purpose? Be sure to include the 3 characteristics that make it up.
What does it mean for data to have variability as it refers to statistical questions? Give an example
Explain the difference between a dot plot and histogram. When would you use each graph?
Explain the difference between center and shape of a data set.
What are outliers and how do they affect a data set? What effect do outliers have on the measures of central tendencies? Which measure would be the best to use?
Answers
Answer: A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer.
Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data.
A histogram is a chart that groups data into classes and displays the frequencies for those classes, while a dot plot illustrates each individual observation along a horizontal number line.
The center is the median and/or mean of the data. The spread is the range of the data. And, the shape describes the type of graph.
The average of set of data that is calculated by dividing the sum of the data by the number of items in the set. ... Measures of central tendency are mean, median and mode. Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
