Answer:
30 cubic feet
Step-by-step explanation:
volume of a pyramid is (l*w*h)=3
assuming it is a pyrmaid where l=w=h, volume = x^3/3 = 10
x^3=30
x=30^(1/3)
volume of a cube is l*w*h, with our assumption, that translates to x*x*x
Volume = 30^(1/3)*3 = 30 cubic feet
1/2 = cos(2*t)sqrt(3) /2 = sin(-2*t)find tfind the time derivative of x(t), y(t)(-2sin(2*t) , -2cos(2*t) )plug in the t you found to find the velocity vector.
Easy the 3 is in the ten thousands place
Answer:
Area = 314.2 cm²
Step-by-step explanation:
Area of a circle = πr²
π = 3.142
r = 10 cm
Area of the circle = 3.142 × 10²
Area = 3.142 × 100
Area = 314.2 cm²
Answer:
a) Standard deviation: 3 bluberries
b) We assume, to apply this rule, that the distribution of blueberries per muffin has a bell-curve distribution, approximately normal.
Step-by-step explanation:
We know that the number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries.
a) If we use the Empirical Rule 68-95-99.7, specifically the last term, we have that:
- 99.7% of the data will fall between 3 standard deviations from the mean.
Then, if we consider the range of 20 to 40 containing 99.7%, we can calculate the standard deviation as:
