What is the area of these

trasher [3.6K]

Answer:

5: 15in 6: 20in 7: 3in 8: 30in

Step-by-step explanation:

Area =1/2 BH so what you do is you multiply the base x the height, then divide by 2, and that is your answer. Hope this helps.

NOTE: Do not forget to add inches 2 after writing the answer. You will be marked wrong for it. Btw 2 = Squared.

Can you just write the answer for b please

pychu [463]

In question a. it supply us with the info needed. So if the water troughs capacity

is $160,000cm^2$

Then we will divide 160,000 by 5,000.

That would equal to 32.

Or 32 pigs per trough.

Hope I helped!

Sunny has a six-sided number cube labeled with the numbers 1 through 6 and a spinner, shown below. What is the probability that

Grace [21]

Answer:

$P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}$

Step-by-step explanation:

Given

$Cube = \{1,2,3,4,5,6\}$

$n(Cube) = 6$

$Spinner = \{A,B,C,D,E,F,G,H\}$

$n(Spinner) = 8$

See attachment for spinner

Required

$P(Cube \ge 5\ and\ Spin[A])$

On a number cube, we have:

$Cube \ge 5 = \{5,6\}$ ---- i.e. 2 outcomes

So, the probability is:

$P(Cube \ge 5) = \frac{n(Cube \ge 5)}{n(Cube)}$

$P(Cube \ge 5) = \frac{2}{6}$

$P(Cube \ge 5) = \frac{1}{3}$

On the spinner, we have:

$Spin [A] = \{A\}$ ---- i.e. 1 outcomes

So, the probability is:

$P(Spin[A]) = \frac{n(Spin[A])}{n(Spinner)}$

$P(Spin[A]) = \frac{1}{8}$

$P(Cube \ge 5\ and\ Spin[A])$ is calculated as thus:

$P(Cube \ge 5\ and\ Spin[A]) = P(Cube \ge 5) * P(Spin[A])$

$P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{3} * \frac{1}{8}$

$P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}$

In a large bag of marbles, 20% of them are red. A child chooses 4 marbles from this bag. If the child chooses the marbles at ran

lubasha [3.4K]

Answer:

0.0256

Step-by-step explanation:

Assuming a binomial model, with probability of success (getting a red marble) p = 0.20. The probability of obtaining 'k' successes in 'n' trials is:

$P(x=k)=\frac{n!}{(n-k)!k!}*p^k*(1-p)^{n-k}$

For k = 3 red marbles in n = 4 trials:

$P(x=3)=\frac{4!}{(4-3)!3!}*0.20^3*(1-p)^{4-3}\\P(x=3)=4*0.20^3*0.8\\P(x=3) = 0.0256$

The probability that the child gets exactly three red marbles is 0.0256.
