Answer:
Nickel and penny.
Step-by-step explanation:
The given pattern is
half dollar, quarter, dime...
This is a part of the pattern of US coins.
The pattern of US coins in decreasing order is
Dollar, half dollar, quarter, dime, nickel, penny.
It is clear that the next 2 words in this pattern after dime are nickel and penny.
Therefore, the required 2 words are nickel and penny.
The correlation coefficient is -0.87; strong correlation
<h3>How to determine the correlation coefficient?</h3>
The given parameters are:
x = Time spent working out
y = lbs Overweight
Next, we enter the table of values in a graphing tool.
From the graphing tool, we have the following summary:
<u>X Values</u>
- ∑ = 27.1
- Mean = 2.71
- ∑(X - Mx)2 = SSx = 22.569
<u>Y Values</u>
- ∑ = 89
- Mean = 8.9
- ∑(Y - My)2 = SSy = 778.9
<u>X and Y Combined</u>
- N = 10
- ∑(X - Mx)(Y - My) = -114.19
<u>R Calculation</u>
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = -114.19 / √((22.569)(778.9))
r = -0.8613
Approximate
r = -0.87
This means that the correlation coefficient is -0.87
Also, the correlation coefficient is a strong correlation, because it is closer to -1 than it is to 0

Answer:
it could be -50.35 and 50.35 since the absolute value is just the positive value of the number
Answer:
1/3
Step-by-step explanation:
The total number of marbles is
6+12 = 18
P( red) = red/total
= 6/18
=1/3
