What is the following product

Answer: 10 books

Step-by-step explanation:

Let the number of books bought be represented by x.

Let the number of dvds bought be represented by y.

The information given in the question can be formed into an equation as:

x + y = 18 ........ i

0.50x + 0.75y = 11 ....... ii

Multiply equation i by 0.75

Multiply equation ii by 1

0.75x + 0.75y = 13.50 ........ iii

0.50x + 0.75y = 11 ........ iv

Subtract iv from iii

0.25x = 2.50

x = 2.50/0.25

x = 10

Answer:

First box is 50%

Second box is 60%

Step-by-step explanation:

Took the test and I got it right :)

The theoretical probability of picking a one-dollar coin from the piggy bank before the draw is 50%, But the experimental probability, based on the draw, is 60%

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

Jonathan's piggy bank contains 20 nickels, 30 quarters, and 50 one-dollar coins.

He picks 20 coins from the bank at random; 12 of these coins are one-dollar coins.

The total number of one-dollar coins = 50

Total number of coins the piggy bank contains = 100

The theoretical probability of picking a one-dollar coin from the piggy bank before the draw = 50/100

                           = 1/2

But the experimental probability, based on the draw, is 60%.

Answer:

7/19

Step-by-step explanation:

In order to find the probability that two events happen in a sequence you simply have to multiply the probability of each individual event together. Since the probability of the sequence is given to us as well as the probability of drawing the first green jelly bean, this means we need to divide the first probability by the probability of the sequence to get the probability of the second event. Basically, reversing the process. Dividing two fractions, we simply divide the numerators by each other and then the denominators by one another.

[tex]\frac{14 / 2}{95 / 5} = \frac{7}{19}[/tex]

Therefore, the probability of picking the second green jelly bean is 7/19

Answer:

(-2,-1)

Step-by-step explanation:

The point (-2, -1) lies on the graph of  y=x²-5

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given function is y=x²-5

A relation is a function if it has only one y-value for each x-value.

We have to find the points which lies on the graph of  y=x²-5

The graph is a parabola which has vertex of (0, -5)

Let us find few points of function

When x=-2, y=-1

When x=0, y=-5

when x=1, y=-4

when x=2, y=-1

when x=3, y=4

when x=4, y=11

when x=5, y=20

Hence, the point (-2, -1) lies on the graph of  y=x²-5

Answer:

the  probability that the two butterflies she spots will both be type A butterflies is 0.0044

Step-by-step explanation:

The computation of the  probability that the two butterflies she spots will both be type A butterflies is shown below:

= 1 ÷ Type A × 1 ÷ Type A

= 1 ÷ 15 × 1 ÷ 15

= 1 ÷ 225

= 0.0044

Hence, the  probability that the two butterflies she spots will both be type A butterflies is 0.0044

the ability to objectively analyze information and draw a rational conclusion

Step-by-step explanation:

The critical thinking skill that is based on logic and reason is "Logical reasoning" or "Logical thinking."

Critical thinking is the process of actively and skillfully analyzing, evaluating, and synthesizing information to make reasoned judgments and decisions.

Among the various critical thinking skills, "Logical reasoning" plays a fundamental role in the process.

Logical reasoning involves using principles of logic and reason to assess arguments, statements, and evidence.

It aims to identify the validity and soundness of claims and draw logical conclusions based on available information.

Hence, logical reasoning is the critical thinking which is based on logic and reason.

Step-by-step explanation:

The chance that round will be won, [tex]P (win) =0.8[/tex]

The likelihood of losing round by complementary law

[tex]P(loss) = 1 -P(win)\\\\[/tex]

            [tex]=1-0.8\\\\=0.2\\\\[/tex]

Let X be the number of rounds to the first loss played.

Here, [tex]X \sim Geometric (p=0.2)[/tex]

The PMF of X is the following:

[tex]P(X=x)=p(1-p)^x\\\\[/tex]

        [tex]=(0.2)(1-0.2)^x\\\\=(0.2)(0.8)^x, \ \ \ \ \ x=1,2,.....[/tex]

The mean of X is the geometric random variable property, [tex]E(X) =\frac{1}{P}= \frac{1}{0.2}=5\\\\[/tex]

Markov's Inequality:

Suppose X is any random variable that has no negatives. So,

[tex]P(X \geq s)\leq \frac{E(X)}{s} for s >0\\\\[/tex]

Find the upper bound of [tex]P (X \geq 10)[/tex]

[tex]P(X \geq 10) \leq \frac{E(X)}{10}[/tex]

                 [tex]=\frac{5}{10}\\\\=\frac{1}{2}\\\\=0.5\\\\[/tex]

 The highest probability is, therefore, that Markov's inequality will win at least ten rounds: 0.500

Step-by-step explanation:

A hockey game has 3 periods.

Now, it is halfway through two periods, which means that 2 + 0.5 = 2.5 periods have been played.

Amount remaining:

Total of 100% = 1, subtracted by the fraction played, which is 2.5 of 3 = 5 of 6. So

[tex]1 - \frac{2.5}{3} = 1 - \frac{5}{6} = \frac{6 - 5}{6} = \frac{1}{6}[/tex]
