Renee is playing a game with marbles and a spinner. The spinner has four sections: orange, black, purple, and white. The marbles are kept in a bag and come in three colors: orange, black, and purple. Renee first spins the spinner and then picks a marble from the bag without looking. What is the probability that the color of the marble matches the color on which the spinner lands? brainly

Answers

Answer:

$(1)/(16)$ Is the chance of the colours matching.

Step-by-step explanation:

The possibility of the spinner landing on an orange side is $(1)/(4)$

and the possibility of the marble being orange is $(1)/(4)$ in this case you have to remember, in the fraction, you have 4 possibilities and 1 desirable outcome, when you have two dependant possibilities you have to multiply them:

$(1)/(4) * (1)/(4)$

And the result of that multipliction is $(1)/(16)$ which is the probability of the marble and the spiner colours matching.

The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports are obtained by subtracting total imports from total exports; a negative net export means the country imported more goods than it exported.What is the sum of net exports for Germany and China ?
a.
-80 billion dollars
c.
90 billion dollars
b.
180 billion dollars
d.
150 billion dollars

Answers

Answer:

d.) 150 billion dollars

Step-by-step explanation:

As per the given bar graph, we can draw the following conclusions:

Net exports for United States = ~ -110 Billion Dollars (It means import of 110 Billion Dollars)

Net exports for Denmark = ~ -30 Billion Dollars (It means import of 30 Billion Dollars)

Net exports for China = ~ 115 Billion Dollars

Net exports for Germany = ~ 35 Billion Dollars

We have to find the sum of net exports of Germany and China:

$\Rightarrow$ 35 + 115 = 150 Billion Dollars.

Hence, correct answer is d. 150 Billion Dollars.

Answer: d

Step-by-step explanation:

150 billion dollars

Answers

Answer:

1. One way to show that a statement is not a good definition is to find a counterexample. A counterexample refers to an exception to the rule, if we deduct that exception is true, then the proposition is completely false. In this case, we have to find an exception to the definition, if the exception is true, then the definition is not true.

2. The option that show a true conditional is the fourth: If it's raining, then the humidity level is 100%. This shows the correct logical conditional, other options are not logical. In this case, the hypothesis is "if it's raining", and the conclusion is "the humidity is 100%". This is the right order, because humidity derive from raining, not the opposite.

The true conditional with a correctly identified hypothesis is:

If it is raining, then the humidity level is 100%.

Hypothesis: It is raining.

Conclusion: The humidity level is 100%.

1. One way to show that a statement isn't a good description is to find a counterexample.

A counterexample refers to an exception to the rule, if we abate that exception is true, also the proposition is fully false. In this case, we've to find an exception to the description, if the exception is true, also the description isn't true.

2. The option that show a true tentative is the fourth If it's raining, also the moisture position is 100.

This shows the correct logical tentative, other options aren't logical. In this case, the thesis is" if it's raining", and the conclusion is" the moisture is 100". This is the right order, because moisture decide from raining, not the contrary.
