Answer 1

Answer:

  9) 1/42

  10) 1/14

Step-by-step explanation:

The probability of the compound event is the product of the probabilities of the parts. Note that the first draw (without replacement) modifies the probability of associated with the second draw.

9.

5 is one of 7 tiles. After drawing 5, 6 is one of 6 tiles.

P(5 then 6) = P(5) × P(6 | 5) = 1/7 × 1/6 = 1/42

10.

There are 3 odd tiles among the 7. After drawing one of them, 20 is one of 6 tiles.

P(odd then 20) = P(odd) × P(20 | odd) = 3/7 × 1/6 = 3/42 = 1/14

_____

Alternatively, you can consider the number of permutations of 2 tiles out of 7. That is P(7, 2) = 7!/(7-2)! = 7·6 = 42. Then the trick is to count how many of them will be the sequence of interest.

5 then 6: Among the 42 ways 2 tiles can be drawn, there is only one that is the required sequence: P(5,6) = 1/42.

odd then 20: There are 3 odd numbers, so the possible sequences of interest are (5,20), (7,20), (9,20). That is, there are 3 of 42 sequential draws that match the criteria. P(odd,20) = 3/42 = 1/14.

Answer 2
Answer:
9) 1/42
10) 1/14

Find the acute angle between two diagonals of quadrilateral ABCD if it is known that AB=BC=CD and AC=BD=AD.

Answers

Answer:

45⁰

Step-by-step explanation:

The quadrilateral ABCD is a square.

Since the question stated that all the sides are equal. (AB=BC=CD)

It also stated that the diagnonals are equal. (AC=BD=AD)

I wish I could draw to explain this easily

A square has four right angles.

A right angle is a 90⁰ angle.

The diagonals divide each 90⁰ angle by 2

I hope you know what a diagonal is.

It is a line from a corner of the square to the opposite corner. This cuts the square into two equal sides.

After drawing the first diagonal two triangles of equal size will be seen.

After drawing the second diagonal the two triangles that appeared will each be cut into halves.

Now, you'll have four equal triangles.

think of it as a square pizza cut into four slices...

Answers

Answer:

Step-by-step explanation:

n(U)=100%

n(S)=70%

n(W)=15%

n(S union w compliment)=20%

n(s intersection W)=?

n(u)=n(s)+ n(w)+ n(s union w compliment)- n(s intersection w)

or 100%=70% +15%+ 20% - n( s intersection w)

or 100%= 95%- n(s intersection w)

or 100%-95%=n(s intersection w)

or 5%= n( s intersection w)

now;

n(only w)=n(w)- n(s intersection w)

              =15%- 5%

               =10%

10%of people only like winter season.

i think the question is to find people who only like winter season.

if not then ans is 15% according to question.

a) The illustration of the given information in a Venn diagram is attached.

b) The percentage of people who liked both seasons is 45%.

c) If 180 people liked the summer season only, proportionately, the number of people who liked the winter season only is 300.

How the Venn diagram is illustrated:

The Venn diagram, which shows similarities and contrasts, can be illustrated based on the given percentages.

Percentages are one of the ways to depict proportions, which are the equation of two ratios.

The percentage of survey people who liked the summer season = 60%

The percentage of survey people who liked the winter season = 70%

The percentage of survey people who liked none of the seasons = 15%

The percentage of participants who liked one of the seasons = 85% (100% - 15%)

The total percentage of survey people who liked either summer or winter = 130% (60% + 70%)

b) The percentage of survey people who liked both seasons = 45% (130% - 85%)

The percentage that liked only summer = 15% (60% - 45%)

The percentage that liked only winter = 25% (70% - 45%)

c) 180 people liked summer only

180 = 15%

Proportionately, if 180 = 15% of the people, the total number of people = 1,200 (180/15%)

The number of people who liked winter season only = 300 (1,200 x 25%)

well, it is supposed to be -3.

but you are right. something is wrong or missing here.

5x + 3 = 4x

x + 3 = 0

x = -3

maybe a "+ 1" is missing on the right side ?

5x + 3 = 4x + 1

gives us

x = -2

Answer:

[tex]4^{2} = 4 x 4 =16[/tex]

Step-by-step explanation:

First of all we need to understand what a perfect square is:

It is an integer which is the square of another integer integer; in other words, it is the product of some integer with itself.

For example: 9, this is a square number since itt equals [tex]3^{2}[/tex] and 3x3 = 9

4x4= 16 when a number is squared like, in this case, 4, you multiple it twice. for instance, 8 squared would be 8x8. it applies to all numbers.

How are the pieces of a step function related to the domain of the function? Justify your thinking.

Answers

Step-by-step explanation:

As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:

[-2.19] = -3

[3.67] = 3

[-0.83] = -1

The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.

This can be generalized as given below:

[x] = -2, -2 ≤ x < -1

[x] = -1, -1 ≤ x < 0

[x] = 0, 0 ≤ x < 1

[x] = 1, 1 ≤ x < 2

As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x.
For example:
1-2.191 =-3
13.671 = 3
[-0.831 = -1
The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on.
This explains the domain and range relations of a step function.

Answers

[]b = 6b - 12

we can start by seeing that b is being multiplied by 6 so we should do the same to 4.

6 * 4 = 24

Next we see that 12 is being subtracted from b so we should do the same to 4.

24 - 12 = 12

Therefore, 12 is your final answer.
The correct is B (12). So []b =6b-12 which means that the expression is just 6*the number -12. So, when you substitute 4 in for b it would turn into 6*4-12 which is 24-12 or 12.

One dozen students each drop a brass tack six times from a height of six inches onto a level hard surface. They record the number of times the tack lands point up. The table below lists their results.

What was the experimental probability that the tack lands point-up for student 7?

0.800

0.833

0.200

Answers

Answer:

0.833

Step-by-step explanation:

1. locate which vertical column of the graph we are referring to:

student 7

2. calculate the total number of trials student 7 did:

if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 65 + 1 = 6

3. refer back to the question:

the question states: "what is the experimental probability that the tack lands point-up"

4. interpret the graph:

of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up. therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)

5. converting from fraction to decimal:

all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form. to convert to decimal form, simply divide the top number by the bottom number5 ÷ 6 = 0.833

therefore, the experimental probability that the tack will land point-up, is 0.833

Step-by-step explanation:

This expression involves the distributive property. In the distributive property, there is a number followed by an equation in parenthesis.

To simplify it, you have to multiply the first number by each number in the parenthesis, separately:

3(n+6)

3n + 3(6) or 3xn + 3x6 (same thing)

3n+18

Finally, we can check the other 4 choices to double check.

A. 3n+6 (wrong)

2xn + 2x6 + n + 6

2n + 12 + n + 6

combine like terms, or all the terms that are the same. start with the Ns, then the numbers:

2n+n + 12+6

C. 2(n+6)+n= 2n+2(6) +n = 2n+12+n= 2n+n+12= 3n+12
