Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

B^2 + 8^2 = 15^2

B^2 + 64 + 225

B^2 = 225 - 64

B^2 = 161

B = $\sqrt{161}$ OR 12.7

strojnjashka [21]

Answer:

3/20 or 15%

Step-by-step explanation:

Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.

To find the probability you need to multiply the two probabilities together.

3/5 times 1/4 is 3/20.

So your answer is 3/20 or 15%.

Answer:

$Probability = 0.2975$

Step-by-step explanation:

Giving:

Swimming

$P(Win[Swim])= 65\%$

Running

$P(Win[Run])= 85\%$

Required

Determine the probability of winning at running and losing at swimming

First, we calculate the probability of losing at swimming using

$P(Win) + P(Lose) = 1$

Substitute 65% for P(Win)

$65\% + P(Lose[Swim]) = 1$

Collect Like Terms

$P(Lose[Swim]) = 1 - 65\%$

$P(Lose[Swim]) = 35\%$

The required probability is then calculated using:

$Probability = P(Win[Run]) * P(Lose[Swim])$

$Probability = 85\% * 35\%$

Convert to decimal

$Probability = 0.85 * 0.35$

$Probability = 0.2975$

Jaden deposited $9000 in a savings account with a simple interest .Two years later the account held up $10,440 what is the inter

Ber [7]

Answer:

Step-by-step explanation:

The simple interest formula is

I = Prt, where I is the interest earned, P is the initial investment, r is the interest rate in decimal form, and t is the time in years. We have that after 2 years, 9000 has turned into 10440. That means that the total interest earned was 10440 - 9000 = 1440

I = 1440

P = 9000

r = ?

t = 2

Filling in we have

1440 = 9000(r)(2) and

1440 = 18000r so

r = .08

As an interest rate, we multiply this by 100 to get 8%

Mila [183]

Answer:

We print -> 21m + 25 ≤ 500
Print so good -> 18m + 44 ≤ 500

Maximum mats from We Print : the integer part of (500-25)/21 = 22

Maximum mats from Print So Good: the integer part of (500-45)/18 = 25

#Note
We take the integer part of the division because a mat cannot be in portions
