Step-by-step explanation:
Answer:
Okay well first we right down what we already know:
- volume of 2,355 cubic inches
- the height is 10 inches
Now we write down the equation for the volume of a cone:
V = πr²
lets plug in what we know into the equation
2,355 = πr²
now we simplify to solve for r
2,355 / 10/3 = 706.5 = πr²
706.5/π = r²= 224.89
now since its r² we take the square root of 224.89
r = 15 inches
for diameter we multiply 15 by 2
diameter = 30 inches
2(3x - 1) ≥ 4x - 6 | Starting equation
6x - 2 ≥ 4x - 6 | Distribute the 2
2x - 2 ≥ -6 | Subtract 4x from each side
2x ≥ -4 | Add -2 to each side
x ≥ -2 | Divide both sides by 2
So, x must be greater or equal to -2 to be in the solution set.
Answer:
Option D, i.e., -0.7.
Step-by-step explanation:
Correlation describes the relation between two variables. It is defined by r and the value of correlation lies in the interval [-1,1].
If r=1, it represents strong positive correlation between two variables.
If r=0, it represents no correlation between two variables.
If r=-1, it represents strong negative correlation between two variables.
It is given that the value of a car decreases with age. The value of one variable decreases if the value of another variable increases. It means, the given problem has negative correlation.
If the data points lie about a straight negative line then coefficient is -1.
Since, the data set is not given, so the it represents moderate negative correlation, i.e, r=-0.7.
Therefore, the correct option is D.
