Answer:

16+8g

Step-by-step explanation:

Just multiple everything by 8

Hope this helps (:

Answer:

8g+16

Step-by-step explanation:

I guess it can be kind of confusing when the number outside of the parentheses is on the right side of the equation? I don't know lol, but the same rules apply.

If it helps, rewrite it as: (2+g)8 --> 8(2+g)

Now multiply: (8*2)+(8*g)

Simplify: 16+8g or 8g+16 (however you want to write it)

Answer:

a) The mean is 225 and the standard deviation is 11.12.

b) It means that in samples of 500 adult Americans, the number of those who believe that the overall state of moral values in the United States is poor is expected to be around 225.

c) No, since 240 is less than 2.5 standard deviations from the mean.

Step-by-step explanation:

For each adult American, there are only two possible outcomes. Either they believe the overall state of moral values in the US is poor, or they do not. The adults are independent of other adults. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

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

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

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

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

In the binomial distribution, a value is considered to be unusual if it is more than 2.5 standard deviations from the mean.

45% of adult Americans believe that the overall state of moral values in the United States is poor.

This means that [tex]p = 0.45[/tex]

(a) Compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values in the United States is poor based on a random sample of 500 adult Americans.

Sample of 500 means that [tex]n = 500[/tex]

Mean:

[tex]E(X) = np = 500*0.45 = 225[/tex]

Standard deviation:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{500*0.45*0.55} = 11.12[/tex]

The mean is 225 and the standard deviation is 11.12.

(b) Interpret the mean.

It means that in samples of 500 adult Americans, the number of those who believe that the overall state of moral values in the United States is poor is expected to be around 225.

(c) Would it be unusual to identify 240 adult Americans who believe that the overall state of moral values in the United States is poor based on a random sample of 500 adult Americans

2.5 standard deviations above the mean is:

225 + 2.5*11.12 = 252.8

So 253 or more would be unusual, 240 no.

Step-by-step explanation:

A tech company bought a number of computers for its employees: 6 costing $1600 each, 4 costing $1200 each, and y costing $900 each, where y is a positive odd integer. what is the greatest possible value of y

Solution:

The median of a group of numbers is the middle number when the group of numbers have been arranged either in ascending of descending other. The median of an even group of numbers is the average of the two most middle most numbers while the median of an odd group of numbers is the middle number.

Since there are 6 computers costing $1600, 4 computers costing $1200 each and y computers costing $900 each. Since y is odd, hence y + 6 + 4 would be odd and the median would be the middle number.

Given that the median price = $1200, this means that the middle of the group of numbers is $1200

900, 900, ..., 1200, 1200, 1200, 1200, 1600, 1600, 1600, 1600, 1600, 1600

Since y is odd, for the median price to be $1200, y has to be 3 or 5.

If y = 3:

900, 900, 900, 1200, 1200, 1200, 1200, 1600, 1600, 1600, 1600, 1600, 1600

median = $1200

If y = 5:

900, 900, 900, 900, 900, 1200, 1200, 1200, 1200, 1600, 1600, 1600, 1600, 1600, 1600

Median = $1200

Therefore the greatest possible value of y is 5

By knowing that the median must be $1,200, we will see that the greatest possible value of y is y = 9.

We know that the company bought:

We know that y is a positive odd number.

We also know that the median is $1200, now we want to get the maximum value of y such that the median is $1200. (Remember that the median is the value of the middle element of the set).

Then we will have the distribution:

{ y elements,  $1200, the other 3 $1200 computers plus the 6 $1600 computers}

Notice that y (the number of elements at the left of the median) must be equal to the number at the right of the median.

At the right of the median, we have a total of 9 computers, then y must be equal to 9.

The greatest possible value of y is 9.

c. Matched-Pair Design

Step-by-step explanation:

The experimental research study showcased above exhibits two different treatments groups ; the new cholesterol lowering drug and the placebo. The allocation of observations or subjects into groups was based on pair selection which is based on whether subjects picked an even or odd number. Subjects who picked the odd are moved to the treatment group of the new drug while those who picked an even number are referred to the placebo treatment group. This type of research design which involves two pairs of treatment and allotment pattern is called a matched pair research design

Answer:

The work done is 3645.6 J or 3.6 kJ

Step-by-step explanation:

M1 = (0.5 kg/m)(12 - x m) = (6 - 0.5x) kg

At the height of x meters (0<=x<=12), the mass of the rope is,

M2 = (36kg/12m)(12 - x m) = (36 - 3x m) kg

At the height of x meters (0<=x<=12), the mass of the water is,

M3 = 10 kg

The mass of the bucket is 10 kg

Then, Total mass M is,

M = M1 + M2 + M3 = (6 - 0.5x) + (36 - 3x) + 10 = (52 - 3.5x) kg

From Force F = mass m * acceleration due to gravity g

Force = mass x gravity

F = 9.8(52 - 3.5x) Newtons

Answer:

They bought 40 shoes and 120 boots.

Step-by-step explanation:

So from the question itself we can make the following equation.

Let "x" be the number of shoes they bought, then...

20(x) + 60(3x) = 8000

20x + 180x = 8000

200x = 8000

x = 8000 / 200

x = 40

From here we know that..

# of shoes they bought = x = 40

# of boots they bough = 3x = (3)(40) = 120

Step-by-step explanation:

The value of C is -3 and the value of B is 5

Given the expression

(2x + 3)(4x − 1)

On expansion, ww will have:

(2x + 3)(4x − 1) = 8x^2 - 2x + 12x - 3

(2x + 3)(4x − 1) = 8x^2 + 10x - 3

Hence the value of C is -3

For the expression (x + 2)(2x^2 + x − 1)

Expnd

(x + 2)(2x^2 + x − 1)  = 2x^3 + x^2 - x + 4x^2 + 2x - 2

(x + 2)(2x^2 + x − 1) = 2x^3+ 5x^2 +x - 2

Hence the value of B is 5
