Find the volume of each of the following cubes. a. s = 7 kilometers b. s = 11 yards

nadya68 [22]

Answer:

Part 1) $V=343\ km^{3}$

Part 2) $V=1,331\ yd^{3}$

Step-by-step explanation:

we know that

The volume of a cube is equal to

$V=s^{3}$

where

s is the length of the cube

Part 1)

we have

$s=7\ km$

substitute in the formula

$V=7^{3}$

$V=343\ km^{3}$

Part 2)

we have

$s=11\ yd$

substitute in the formula

$V=11^{3}$

$V=1,331\ yd^{3}$

A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tent

lisabon 2012 [21]

Hello!

We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.

To solve, we just multiply the two probabilities.

$\frac{170}{400}(1/2)$ =0.2125≈21.3

Therefore, we have about a 21.3% chance of this event occurring.

I hope this helps!
