Simplify 2(12-18\3+4)

Question

Simplify

[tex]2(12 - \frac{18}{3} + 4)[/tex]

Answer:-

ATQ->

[tex]2(12 - ( \frac{ \cancel{18}^{ \: \: \: 6} }{3} ) + 4 \\ 2(12 - 6 + 4) \\ 2(16 - 6) \\ 2(10) \\ 20 \: \: is \: your \: ans[/tex]

Answer:

Depends on how the 3 and the 18 are positioned in the fractions on the equation.

47/3

4

Step-by-step explanation:

Step 1. To simplify this, you need to know one of the most basic sayings in math which summarizes the Order of Operations: PEMDAS

Using PEMDAS:

P- Parenthesis

E- Exponents

M- Multiply

D- Divide

A- Add

S- Subtract

P- Parenthesis: We start off by preforming the parts of the equation within the parenthesis.

The 2 on the outside of the parenthesis, will not affect anything until we deal with what is inside the parenthesis.

The next part that we do, is to go through the rest of the steps, looking for either exponents, multiplication or division, skipping over the adding and subtracting until those are done.

The next part that we see, is Division.

D- Division

We find the point of division after the 18. The value we get has to be either:

a. 3/18

b. 18/3

depending on what you were asking for.

The equation, 2(12-18\3+4) at the bolded point, states that the division should be 1/6 because of the way of the division symbol.

Now the equation should either be one of the following:

a. 2(12-1/6+4)

b. 2(12-6+4)

A-Addition

Now, we can add the 4 to the number we got before, which should get us either

A. 1/6+4

B. 6+4

which added together gets us either

A. 25/6<=>4+1/6

B. 10

S-Subtraction

Now, we subtract both parts from the value of 12 getting us:

A. 12-(4+1/6)=12-4-1/6=8-1/6=7+5/6<=>47/6

B. 12-10=2

M-multiply:

Now we move on to the 2 we put aside earlier and multiply both of the answers:

A. 2(47/6)=47/3 or 15+2/3

B. 2(2)=4

Thus the answer is either 47/3 or 4

There are four different colored balls in a bag. There is equal probability of selecting the red, black, green, or blue ball.What is the expected value of getting a green ball out of 20 experiments with replacement?

Answers

Answer:

The expected value is of 5 green balls.

Step-by-step explanation:

For each experiment, there are only two possible outcomes. Either it is a green ball, or it is not. Since there is replacement, the probability of a green ball being taken in an experiment is independent of any other experiments, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

20 experiments

This means that [tex]n = 20[/tex]

There is equal probability of selecting the red, black, green, or blue ball.

This means that 1 in 4 are green, so [tex]p = \frac{1}{4} = 0.25[/tex]

What is the expected value of getting a green ball out of 20 experiments with replacement?

[tex]E(X) = np = 20*0.25 = 5[/tex]

The expected value is of 5 green balls.

The expected value of getting a green ball out of 20 experiments with replacement is 5.

What is a binomial distribution?

The binomial probability distribution of the number of successes in a sequence of n independent experiments is the binomial distribution with parameters n and p.

As it is given that the probability of all the balls coming out of the bag is equal. Therefore, the probability of a green ball coming can be written as,

[tex]\text{Probability of Green Ball} = 0.25[/tex]

Also, we can write the probability of not getting a green ball can also be written as,

[tex]\rm Probability(\text{Not coming Green Ball}) = P(Red\ ball)+P(Black\ ball)+P(Blue\ ball)[/tex]

                                                         [tex]=0.25+0.25+0.25\\\\=0.75[/tex]

Now, as there are only two outcomes possible, therefore, the distribution of the probability is a binomial distribution. And we know that the expected value of a binomial distribution is given as,

[tex]\rm Expected\ Value, E(x) = np[/tex]

where n is the number of trials while p represents the probability.

Now, substituting the values, we will get the expected value,

[tex]\rm Expected\ Value, E(Green\ ball) = 20 \times 0.25 = 5[/tex]

Hence, the expected value of getting a green ball out of 20 experiments with replacement is 5.

Answers

Answer: Either 2, 5, or 8

This means the number 426 is divisible by 6. So are 456 and 486

===============================================================

Explanation:

A number is divisible by 6 if both of the following are true

The number is divisible by 2The number is divisible by 3

This is simply because 6 = 2*3. So if 6 is a factor of a number, then 2 and 3 must be factors.

To have 2 be a factor, the units digit must be in the set {0,2,4,6,8} which is the case here (the units digit is 6 in this case). Therefore we know the number is a multiple of 2 regardless of what the other digits are. To have 3 be a factor, the digits must add up to a multiple of 3. Through trial and error, we see that 0 doesn't work because 4+0+6 = 10 which is not a multiple of 3. Same goes for 4+1+6 = 11, but 4+2+6 = 12 is a multiple of 3.

Therefore, 426 is a multiple of 6

Increment that middle digit 2 by 3 and we jump from 426 to 456. Those three digits add to a multiple of 3 as well (4+5+6 = 15). Following that line of logic, we go from 456 to 486 as the last possible three digit number that has these conditions of having 4 first and 6 last, and the number is a multiple of 6.

-------------------------------

In short,

The numbers 426 and 456 and 486 are all multiples of 6 since they are multiples of 2 and 3 at the same time.

So we could replace that middle digit with either 2, 5 or 8.

At noon, ship A is 150 km west of ship B. Ship A is sailing east at 30 km/h and ship B is sailing north at 25 km/h. How fast is the distance between the ships changing at 4:00 PM?

Answers

Answer:

At 4:00 PM the distance between the two ships is 104.40 kilometers.

Step-by-step explanation:

Given that at noon, ship A is 150 km west of ship B, and ship A is sailing east at 30 km / h and ship B is sailing north at 25 km / h, to determine how fast is the distance between the ships changing at 4:00 PM the following calculation must be performed:

150 - (30 x 4) = 150 - 120 = 30

0 + (25 x 4) = 0 + 100 = 100

30 ^ 2 + 100 ^ 2 = X ^ 2

√ (900 + 10,000) = X

√10,900 = X

104.40 = X

Therefore, at 4:00 PM the distance between the two ships is 104.40 kilometers.

Which of the following is result of using the remainder theorem to find F(3) for the polynomial function F(x) = x^3 - 9x^2 + 5x - 2


A. -32

B. 11

C. -59

D. -41

Answers

Answer:

-41

Step-by-step explanation:

The remainder theorem states that when a polynomial F(x) is divided by (x - k) the remainder is F(k). In other words, the remainder when f(x) is divided by (x-k) is calculated by simply calculating F(k).

Given:

F(x) = x³ - 9x² + 5x - 2                   -----------------(i)

To calculate F(3), substitute x = 3 into equation (i) as follows;

F(3) = (3)³ - 9(3)² + 5(3) - 2

F(3) = 27 - 81 + 15 - 2

F(3) = -41

This means that if the polynomial F(x) = x³ - 9x² + 5x - 2 is divided by x - 3, the remainder will be -41.

y-2x-1=0 for -2 ≤ x ≤ 4 . can someone help me graph a straight line for this pls ?​

Answers

Answer: See the graph below.

It is a straight line segment with endpoints (-2,-3) and (4,9).

===============================================================

Explanation:

We're told that x is between -2 and 4, including both endpoints.

Let's see what y is when we plug in x = -2

y-2x-1 = 0

y-2(-2)-1 = 0

y+4-1 = 0

y+3 = 0

y = -3

So x = -2 pairs up with y = -3. The point (x,y) = (-2,-3) is on the line. This is the left most endpoint.

Repeat for x = 4 to find what y must be

y-2x-1 = 0

y-2(4)-1 = 0

y-8-1 = 0

y-9 = 0

y = 9

Therefore the point (x,y) = (4,9) is also on the line. It's the right most endpoint

Once we have the two points, we can form the straight line. Simply connect the endpoints mentioned as shown below. We don't extend the line infinitely outwards in both directions because [tex]-2 \le x \le 4[/tex] meaning x cannot be smaller than -2, and x cannot be greater than 4 either.

Side note: The given equation is the same as y = 2x+1. It has slope 2 and y intercept 1.

82 less than r is less than -164

Answers

Answer:

82<r<-164

Step-by-step explanation:

We need to form an inequality of the given statement.

82 less than r is less than -164

Less than is written as <.

82 less than r means, 82<r

r is less than -164, r<-164

Combining two statements,

82<r<-164

Hence, the expression for 82 less than r is less than -164 is 82<r<-164.

The ranges of g(x) and f(x) are the same, and their domains are also the same.
The domains of g(x) and f(x) are the not the same, and their ranges are also not the same.

Answers

Answer:

In general gf(x) is not equal to fg(x)

Some pairs of functions cannot be composed. Some pairs of functions can be composed only  for certain values of x.

Only with they can be composed some values of x are the ranges of g(x) and f(x) are the same, and their domains are also the same. Or else lies inside it.

Step-by-step explanation:

g(x) = 3x + 6 - 8, f(x) = √x.

The domain of a composed function is either the same as the domain of the first function, or  else lies inside it

The range of a composed function is either the same as the range of the second function, or else lies inside it.

Or vice versa

Now only positive numbers, or zero, have real square roots. So g is defined only for numbers

greater than or equal to zero. Therefore g(f(x)) can have a value only if f(x) is greater than or

equal to zero. You can work out that

f(x) ≥ 0 only when x ≥3/2

Phat ± Zα/2* [√Phat(1 - Phat) / n]

The 90% Z critical value is = 1.645

0.8492 ± 1.645*[√0.8492(1 - 0.8492) / 325)

0.8492 ± 1.645*[√0.8492(0.1508) / 325]

0.8492 ± 1.645*√0.0003940288

0.8492 ± 0.0326535

Lower boundary = 0.8492 - 0.0326535 = 0.8165
