Answer:
My number will be 44.
Step-by-step explanation:
- My number will be divided by 2.
- I will get 22.
- Then I'll 2 to my 22.
- It will give me 24.
- <u>44 divided by 2 = 22</u>
- <u>22 + 2 = 24</u>
Answer:
The answer to your question is:
Step-by-step explanation:
1.-
Data
3.3 x 10 ⁴ pounds of paper
1.5 x 10³ pounds of aluminum
Amount of aluminum / amount of paper = 1.5 x 10³ / 3.3 x 10⁴
= 0.045 times
= 4.5 x 10 ⁻²
2.-
Data
1.2 x 10 ³ text messages in a month
text messages in a year = ?
1.2 x 10³ text messages ------------------- 1 month
x ------------------- 12 months
x = (12 x 1.2 x 10³) / 1
x = 14400 text messages
x = 1.44 x 10⁴ text messages
3.-
Data
distance = 4 x 10⁶ miles I am not sure if the power is 6 or 8
speed = 1.6 x 10³ mi/h
Formula
time = distance / speed
time = 4 x 10⁶ / 1.6 x 10³
time = 2500 h
time = 2.5 x 10 ³ h
Answer:
Strong positive correlation
Step-by-step explanation:
The given scatterplot, where the data points are sloping upward:
The stronger the association of the two variables, the closer the Pearson correlation coefficient, <em>r</em>, will be to either +1 or -1 depending on whether the relationship is <em>positive</em> or <em>negative</em>, respectively.
If the value of the correlation coefficient is 0 < <em>r</em> < 1 then there is a positive linear trend and the data points are scattered around the line of best fit; the smaller the absolute value of <em>r, </em>the less well the data can be visualized by a single linear relationship. The closer the value of r to 0 the greater the variation around the line of best fit.
In the attached screenshot, where I've drawn a line across the graph: it shows that the data points are clustered around the line. It is easier to estimate that the value of <em>r </em>is closer to 1, which implies a strong positive relationship between two variables. My estimate is that <em>r</em> = 0.8.
Therefore, the correct answer is Strong Positive association.

The value of y is 116 degrees
<h3>How to solve for y?</h3>
To solve for y, we make use of the following angle theorem.
The angle at the center is twice the angle at the circumference.
So, we have:
y = 2 * 58
Evaluate the product
y = 116
Hence, the value of y is 116 degrees
