Answer:

1.) very large sample size

2.) 0.11326

3.) np and n(1-p) should be ≥ 10

4.) 0.010809

Step-by-step explanation:

Given :

p = 0.65 ; n = 500

2.)

P(x ≤ 300)

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Using a binomial probability calculator :

P(x ≤ 300) = 0.11326

To justify why if it can be approximated using a normal distributon :

np and n(1-p) should be ≥ 10

np = 500 * 0.65 = 325

n(1-p) = 500(1 - 0.65) = 175

4.) probability using normal distribution estimate:

Mean, m = np = 500 * 0.65 = 325

Standard deviation, s = sqrt(n*p*(1-p)) = sqrt(500*0.65*(1 - 0.65)) = sqrt(113.75) = 10.665

x ≤ 300

Correction:

x = x + 0.5 = 300 - 0.5 = 300.5

P(x ≤ 300.5)

Zscore = (x - m) / s

Zscore = (300.5 - 325) / 10.665

Zscore = - 24.5 / 10.665

Zscore = - 2.297

P(Z ≤ - 2.297) = 0.010809

X can be modeled by a binomial distribution even though the sample was selected without replacement because the sample size is too large, and the probability that 300 or fewer high school students in the sample eat breakfast before going to school is 0.010809.

Given :

1) X can be modeled by a binomial distribution even though the sample was selected without replacement because the sample size is too large.

2) The formula for the binomial distribution is given by:

[tex]\rm P (x=x)= \; ^nC_x \times p^x \times (1-p)^{n-x}[/tex]

Now, substitute the known terms in the above formula.

[tex]\rm P (x\leq 300)= \; ^{500}C_x \times (0.65)^x \times (1-0.65)^{500-x}[/tex]

Simplify the above expression.

[tex]\rm P(x \leq 300)=0.11326[/tex]

3) Now, the value of np and n(1 - p) is given below:

np = 500 [tex]\times[/tex] 0.65 = 325

n(1 - p) = 500 [tex]\times[/tex] (1 - 0.65) = 175

X can be approximated by a Normal distribution because the value of np and n(1 - p) is greater than or equal to 10.

4)

First, determine the standard deviation.

[tex]\rm \sigma = \sqrt{np(1-p)}[/tex]

[tex]\rm \sigma = \sqrt{500\times 0.65 \times (1-0.65)}[/tex]

[tex]\rm \sigma = 10.665[/tex]

Now, the z-score can be calculated by using the formula:

[tex]\rm z =\dfrac{X-\mu}{\sigma}[/tex]

[tex]\rm z =\dfrac{300.5-325}{10.665}[/tex]

z = -2.297

So, the probability that 300 or fewer high school students in the sample eat breakfast before going to school is given by:

[tex]\rm P(Z\leq -2.297) = 0.010809[/tex]

Answer:

So the answer is A-The mean doesn't change

Step-by-step explanation:

With the outliers the mean is 25, how?

well if we put down the numbers 15,23,24,25,26,27,35 and add them together  15+23+24+25+26+27+35 we get 175 now we have to divide by how many numbers are there 175/7=25. That is the mean WITH the outliers.

Now, WITHOUT the outliers. The outliers are 15 and 35. We know this because, there is a huge gap between 15 and 23, and 27 and 35. We basically do the same thing but without the outliers. 23+24+25+26+27=125 we divide by how many numbers are there 125/5 then we get 25.

Hey love! <3

Answer:

The correct answer is A. The mean doesn't change

Step-by-step explanation:

Since this is a dot plot, first we have to count up the total x-axis amount from the dot plots, then divide it by the numeral amounts (y-axis), then repeat this after removing the outlier from the dot plot.

Thus, the mean remaining the same.

Answer:

  1 (dollar per subscription)

Step-by-step explanation:

a) The term "rate of change" refers to "slope" or "unit rate" on a graph. In a linear equation, it is the coefficient of the variable.

On the graph, it can be found by counting the vertical units that correspond to each horizontal unit. On this graph, a horizontal increase of 1 grid square (5 subscriptions) causes an increase of 1 grid square ($5) in earnings. The rate of change is ...

  m = rise/run = $5/(5 subscriptions) = $1 per subscription

__

c) As indicated above, this will translate to the coefficient of the variable in the equation.

Based on these calculations, Erica would have a higher total amount of savings than Darrell at the end of one year.

Multiplication is an arithmetic operation used to find the product of two or more numbers. It is a way of adding a number to itself a certain number of times. For example, the product of 2 and 3 is 6, which is obtained by adding 2 to itself three times (2 + 2 + 2). Multiplication can be represented using the multiplication sign "×" or the dot symbol ".", and the result is called the product. The numbers being multiplied are called factors.

To compare the total amount of savings Erica and Darrell have at the end of one year, we need to calculate their savings at the end of the year based on their initial savings and monthly deposits. For Erica, the total amount of savings after one year can be calculated as follows:

Total savings for Erica = 200 + (75 x 12) = 200 + 900 = 1100 dollars

For Darrell, the total amount of savings after one year can be calculated as follows:

Total savings for Darrell = 350 + (50 x 12) = 350 + 600 = 950 dollars

Therefore, based on these calculations, Erica would have a higher total amount of savings than Darrell at the end of one year.

Answer:

22.74 liters

Step-by-step explanation:

GIven data

Felix's washing machine uses 6 gallons of water

we are told that  A gallon is approximately 3.79 liters

Hence if  a gallon is approximately 3.79 liters

then 6 gallons of water will be x liters

cross multiply we have

x= 6*3.79

x= 22.74 liters

Hence 6 gallon will be 22.74 liters

Using it's formula, the distance between these two points is given by:

[tex]\sqrt{97}[/tex].

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For this problem, the points are:

(2,4) and (6,-5).

Hence the distance is given by:

[tex]D = \sqrt{(6 - 2)^2+(-5 - 4)^2} = \sqrt{97}[/tex]
