What times what equals 16

1 answer:

4 0

<span>We can find the factors of 16 to get answer to what time what is 16. Now, The factors of 16 are 1,2,4,8,16. Thsu, 16 can be written as: 16=1*16 ; `6 = 2*8 ; 16 = 4*4. Thus, we can say 4 times 4 is 16, 16 times 1 is 16, 2 times 8 is 16.</span>

I just need help finding h pleasww

SCORPION-xisa [38]

Answer:

h = (2/3)√3
b = 3√2

Step-by-step explanation:

It is useful to remember the ratios between the side lengths of these special triangles.

30°-60°-90° ⇒ 1 : √3 : 2

45°-45°-90° ⇒ 1 : 1 : √2

h is the shortest side, and the given length is the intermediate side. This means ...

h/1 = 2/√3

h = 2/√3 = (2/3)√3 . . . . . . simplify, rationalize the denominator

b is the longest side, and the given length is the short side. This means ...

b/√2 = 3/1

b = 3√2 . . . . . multiply by √2

On a particular game show, there are 8 covered buckets and 2 of them contain a ball.

kobusy [5.1K]

Answer:

0.2143 = 21.43% probability that a contestant wins the game if he/she gets to select 4 of the buckets.

Step-by-step explanation:

The buckets are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

8 covered buckets, so N = 8.

4 buckets are selected, so n = 4.

2 contain a ball, which means that k = 2.

Find the probability that a contestant wins the game if he/she gets to select 4 of the buckets.

This is P(X = 2). So

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,8,4,2) = \frac{C_{2,2}*C_{6,2}}{C_{8,2}} = 0.2143$

0.2143 = 21.43% probability that a contestant wins the game if he/she gets to select 4 of the buckets.

Number 6. I have no idea how to do this because the question doesn’t give enough information

Savatey [412]

${13}^{2} = {5}^{2} \times {b}^{2} \\ 169 = 25 \times {b}^{2} \\ 165 - 25 = {b}^{2} \\ 144 = {b}^{2} \\ \sqrt{ {b}^{2} } = \sqrt{144} \\ b = 12$

Jamie is helping out in the school library. He needs to figure out how many shelves the library staff should order for a new rea

Serhud [2]

Answer:

8 shelves

Step-by-step explanation:

First do 378 divided by 50 then you when you get your answer (with remaining numbers) you add one more book case so 378 divided by 50 is 7 then you have a remainder 28 so add another shelf which is now 8 shelves!
