I believe it would be (b) (-2,1)
Answer:
a) -0.5
Step-by-step explanation:
Correlation
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5
Answer:
Step-by-step explanation:
1. trapezoid
2. no not possible lol how do you even do that lol a square has only 90 degree angles and then an obtuse angle pops in no doesn't happen
3. yes just draw two random right angles and then make them intersect lol
4. rectangle, perimeter of 30
5. no
V=<span><span>π <span>r^2</span></span><span>h/<span>3
V = </span></span></span>π r 5^2 16/3
Raise 5<span> to the </span>power<span> of </span>2<span> to get </span><span>25.
</span><span>V=π*25*<span>16/3
</span></span>Move 25<span> to the left of the </span>expression <span><span>π⋅25</span>.
</span><span>V=25*π*<span>16/3
</span></span>Multiply 25<span> by </span>π<span> to get </span><span><span>25π</span>.
</span><span>V=25π*<span>16/3
</span></span>
Multiply <span>25π</span><span> by </span><span>163</span><span> to get </span><span><span>25π(<span>16/3</span>)</span>.
</span><span>V=25π(<span>16/3</span>)</span>
Simplify
Multiply 16<span> by </span>25<span> to get </span><span>400.</span>
<span>V=(<span>400/3</span>)π</span><span>
</span>
Combine <span>400/3</span><span> and </span><span>π/1</span><span> to get </span><span><span><span>400π/</span>3</span>.
</span><span>
V=<span><span>400π/</span>3</span></span>
V≈<span>418.8790</span>
The restrictions are:
1) x ≥ 0
2) number of lower bowl seats = 65% * 18500 = 12,025
=> x ≤ 12,025
3) y ≥ 0
4) number of upper bowl seats = 35% * 18500 = 6,475
=> y ≤ 6,475
It is not necessary to state that x + y ≤ 18,500 because it is included in the other restrictions.
