5. What is the probability that a number picked from the set {-4,-3,-2,-1,0,1,2,3,4,5) will be a

tatiyna

Answer:

70%.

Step-by-step explanation:

Rearrange the inequality to isolate $x$ . Start by subtracting $5$ from both sides of the inequality:

$2\,x + 5 - 5 > 1 - 5$ ,

$2\, x > -4$ .

Divide both sides by $2$ . (Keep in mind that if the multiplier or divisor is smaller than zero, it will flip the inequality sign.)

$x > -2$ .

There are ten numbers in this set. Only seven of them will satisfy this inequality. Note that the " $>$ " symbol means strictly greater than (while " $\ge$ " means greater than or equal to.) As a result, $x = -2$ will not count as a solution.

Assume that the number is picked randomly.

$\begin{aligned}&\text{Probability of Success} \cr = & \dfrac{\text{Number of Choices that lead to Success}}{\text{Number of all Choices}} \cr =& \dfrac{7}{10} \cr = &0.7 \cr =& 70\% \end{aligned}$ .

20 - 3(3x - 4) <br> Solve the equation

Pavlova-9 [17]

Answer:

32 - 9 x (don't know what you want simplify or solve for x) x = 32/9

Step-by-step explanation:

Simplify the following:

20 - 3 (3 x - 4)

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x

20 + 12 = 32:

Answer: 32 - 9 x

_________________________________

Solve for x:

20 - 3 (3 x - 4) = 0

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20 = 0

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x = 0

20 + 12 = 32:

32 - 9 x = 0

Subtract 32 from both sides:

(32 - 32) - 9 x = -32

32 - 32 = 0:

-9 x = -32

Divide both sides of -9 x = -32 by -9:

(-9 x)/(-9) = (-32)/(-9)

(-9)/(-9) = 1:

x = (-32)/(-9)

Multiply numerator and denominator of (-32)/(-9) by -1:

Answer: x = 32/9

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
