Answer:

Angle B = 75 degrees

AC = 35.7

BC = 9.6

Step-by-step explanation:

Angle A = 15 degrees (given)

Angle C = 90 degrees (given)

c = 37 (given)

Angle B = 90-15 = 75 degrees

AC = AB cos(A) = 37 cos(15) = 35.7

BC = AB sin(A) = 37 sin(15) = 9.6

There is 0.62137119 miles to 1 kilometer so 8 kilometers = 4.971 or (5 miles rounding) multiply 0.6 x 8 = 4.971 but u can sensibly say 5 miles

The distribution of the animals in the coral reef is an illustration of probability

<h3>The most likely animal</h3>

The distribution of the animals is given as:

Blue fish = 3

Yellow fish = 7

Sea turtle = 1

Eels = 3

The animal with the highest frequency is the most likely animal.

Hence, the Yellow fish is the most likely animal.

<h3>Which is more likely?</h3>

From the question, we have:

Blue fish = 3

Eels = 3

Both animals have the same frequency.

This means that Riley has equal chance of seeing a blue fish and an eel.

<h3>The probability of seeing an animal with fins</h3>

The animal with fins are:

Blue fish = 3

Yellow fish = 7

So, the probability is:

$p = \frac{3 + 7}{3 + 7 + 1 + 3}$

$p = \frac{10}{14}$

Simplify

$p = \frac 57$

Hence, the probability of seeing an animal with fins is 5/7

<h3>The least likely animal</h3>

The animal with the least frequency is:

Sea turtle = 1

So, the likelihood is:

$p = \frac 1{14}$

Hence, the sea turtle has the least likelihood of 1/14

<h3>Animals with equal likelihood</h3>

The Blue fish and the Eels have the same frequency of 3

This means that animals have equal likelihood

<h3>The probability of seeing each animal</h3>

We have:

Blue fish = 3

Yellow fish = 7

Sea turtle = 1

Eels = 3

Express as probability

Blue fish = 3/14

Yellow fish = 7/14

Sea turtle = 1/14

Eels = 3/14

Express the fractions as decimals

Blue fish = 0.214

Yellow fish = 0.500

Sea turtle = 0.071

Eels = 0.214

So, their likelihoods are:

Blue fish = Equally likely

Yellow fish = Certainly likely

Sea turtle = Unlikely

Eels = Equally likely

If anna is 11 years older than Robert and robert is 2 years younger than sara david is 8 years older than Sara how old is everyo

grigory [225]

Answer:

The information given is not enough to determine their ages explicitly, so, here their ages are given in terms of Anna's age, which is the best that could be determined.

Anna's age = x years

Robert's age = (x - 11) years

Sara's age = (x - 9) years

David's age = (x - 1) years

Step-by-step explanation:

Let Anna be x years old.

Anna's age = x

Because Anna is 11 years older than Robert, we can say Robert's age is Anna's age minus 11.

Robert = x - 11

But Robert is 2 years younger than Sara, we can say Sara's age is Robert's age plus 2

Sara = (x - 11) + 2

= x - 9

David is 8 years older than Sara, we can say David's age is Sara's age plus 8.

David = (x - 9) + 8

= x - 1
