Answer:
13 inches
Step-by-step explanation:
length of side of cube: x
volume of cube = x³ = 2300
x = ∛2300 = 13.2
The arc length of a subtending arc on a circle has the formula:
s = r<span>θ
where is the arc length
r is the radius
</span><span>θ is the angle subtended
</span>
So,
θ = s/r = 8π / 4.5 = 16<span>π/9
We multiply it with 180/</span><span>π to convert it to degrees.
</span>(16π/90) (180/π) = 320<span>°</span>
Replace x with the x values of the choices and see if it solves to equal the y value:
Y=-7x + 2
A) (1,2)
Y = -7(1) + 2 = -7 + 2 = -5 not 2
A is wrong
B (8,-54)
Y = -7(8) + 2 = -56+ 2 = -54
This works out.
The answer is B
Answer:
4 + 2 + q - 1 + q = 15
Step-by-step explanation:
P = 4 + 2 + q - 1 + q = 15
Answer:
Step-by-step explanation:
A possible study is to compare the prices of items in a two different online auction platform: the Dutch auction and the first-priced sealed auction.
Independent variable = the two types of auction
• Condition A = Dutch auction
• Condition B = First-price sealed auction
The Dependent variable in my case study is the prices for each pair of identical items I place in each auction using a known pair sample. The depends variable is measured in the continuous scale because prices are in numbers and these numbers vary continuously, it is not fixed.
The null hypothesis for my study would be: there is no difference in the prices of identical items in the two different auction.
The alternative hypothesis for my study would be: there is a difference in the prices of identical items in the two different auction.
I would set it to the 0.05 level of significance because this is the standard level of significance normally set in a study although this varies.
