Write an inequality for the situation. all real numbers at most –9.5 or at least 5.5A. –9.5 ≤ b ≤ 5.5

B. b ≥ –9.5 or b ≥ 5.5

C. b ≤ –9.5 or b ≤ 5.5

D. b ≤ –9.5 or b ≥ 5.5

Answers

Answer:

option (c) is correct.

The given expression all real numbers at most –9.5 or at least 5.5 is written as   b ≤ –9.5  or  b ≥ 5.5

Step-by-step explanation:

Given  expression all real numbers at most –9.5 or at least 5.5

We have to represent the given expression mathematically and choose the correct from given options.

Consider the given expression  all real numbers at most –9.5 or at least 5.5

Let the real number be represented by b

then the given expression contain two terms

1)  all real numbers at most –9.5  

Mathematically written as  b ≤ –9.5    .....(1)

2) all real numbers at least 5.5

Mathematically written as  b ≥ 5.5       ....(2)

Thus, the given expression   all real numbers at most –9.5 or at least 5.5 is written as   b ≤ –9.5  or  b ≥ 5.5

Thus, option (c) is correct.

A bag contains 8 red, 4 blue, and 4 yellow marbles. What is the probability of randomly choosing 2 blue marbles without replacement? Write the answer as a decimal. Round to the nearest hundredth if needed. And What is the probability of getting heads, tails, and heads, in that order when flipping a coin? are these events dependent or independent? A. 1/8 dependent B. 1/8 independent C. 1/6 dependent D. 1/6 independent. Please help me i really need it thank you so much for whoever helps me.

Answers

Answer: The probability of randomly choosing 2 blue marbles without replacement is 0.05.

B. The probability of getting heads, tails, and heads, in that order when flipping a coin is 1/8.

These events are independent.

Step-by-step explanation:

Given: The number of blue marbles in the bag = 4

The total number of marbles in the bag = 8+4+4=16

After choosing one marble, the total marbles remains in the bag = 16+1=15

If first marble is blue, then number of blue marbles in bag =

Now, the the probability of randomly choosing 2 blue marbles without replacement is given by :-

(4)/(16)*(3)/(15)=(1)/(20)=0.05

Hence, the probability of randomly choosing 2 blue marbles without replacement is 0.05.

In order when flipping a coin.

Total outcomes = 2

Then, the probability of getting heads, tails, and heads, in that order when flipping a coin is given by :-

(1)/(2)*(1)/(2)*(1)/(2)=(1)/(8)

These events are independent of each other because the next event is not affected by the previous event.
bags = 8+4+4=16
firs step
p1=4/16
second step
p2=3/15
P=4/16*3/15=1/4*1/5=1/20=0,05 - correct answer
