A large beach ball has a diameter of 36 inches.what is the approximate volume of the beach ball?

2 answers:

8 0

Because a beach volleyball is a sphere, so the volume formula is V= 4pi r^3/r
so the answer would be <span>24,429.024 </span>

V=24416.64 would be the volume of the entire beach ball

Answer:

Prime.

Step-by-step explanation:

$x^2-7x+8\\$

First let's multiply our outer coefficients in this case 1 and 8, so we have 1x8=8. Now the point of this is to get the factors of 8 and see if we can get that middle term -7. Factors of 8 are 1x8, 2x4 and that's it. From there I notice that -8+1 = -7 and so:

$x^2-7x+8 = x^2-8x+x+8 = x(x-8)+(x+8)$

Notice that the (x-8) and (x+8) are not the same factors, therefore the factors are not any of those answer choices and so it's prime. You can calculate the factors by using the quadratic formula, however I think that is beyond the scope of this question.

Answer:

Option b, c and e are wonderful approaches to solve the problem.

Step-by-step explanation:

Option (b) is appropriate this is because the option is talking about Simple random sampling where random universities are chosen to remove bias.

Option (c) is correct because this is an example of Stratified sampling where two homogenous groups (private and public universities are considered) and samples are chosen at random to remove bias

Option (e) is correct because this again is an example of Simple random sampling where 60 random STEM majors are chosen at random.

A house appreciates (grows in value) about 6% each year. If the house is now worth 158,000, in about how many years will it be w

expeople1 [14]

200,000 = 158,000(1.06)^x
Divide both sides by 158,000
1.2658 = 1.06^x
Take the log of both sides and use the power rule to bring down the exponent (x) to the front.
log 1.2658 = x log 1.06
Divide both sides by log 1.06
log (1.2658)/log(1.06) = x
x = 4 years

CHECK
y = 158,000(1.06)^4
y = 199,471.36
