The scores of 12th-grade students on the National Assessment of Educational Progress year 2000 mathematics test have a distribution that is approximately Normal with mean μ = 300 and standard deviation σ = 35. (a) Choose one 12th-grader at random. What is the probability that his or her score is higher than 300? Higher than 335? Explain and show your work. (b) Now choose an SRS of four 12th-graders and calculate their mean score x. If you did this many times, what would be the mean and standard deviation of all the x-values? Explain and show your work. (c) What is the probability that the mean score for your SRS is higher than 300? Higher than 335? Explain and show your work.

a) To find the probability that the score is higher than 300 you have to find the Z-score for 300, by using the formula:

[tex]\begin{gathered} Z=\frac{x-\mu}{\sigma} \\ Z=\frac{300-300}{35}=\frac{0}{35}=0 \end{gathered}[/tex]The probability of x>300 P(z>0)=1-P(z<=0)

Using the Standard Normal Cumulative Probability Table, P(z<=0)=0.5

Then,

[tex]P(Z>0)=1-0.5=0.5[/tex]Now, you can do the same to find the probability that the score is higher than 335, let' see:

[tex]Z=\frac{335-300}{35}=\frac{35}{35}=1[/tex]The probability of x>335 is P(Z>1), then

[tex]P(Z>1)=1-P(Z\leq1)=1-0.8413=0.1587[/tex]These results mean that it is a 50% of probability that the score of the student chosen is greater than 300, and a 15.87% of probability that the score is greater than 335.

b) SRS=4, their mean score will be the same as the mean of the population = 300, the standard deviation of the sample is the standard deviation of the population divided by √n (n is the size of the sample=4).

[tex]\mu=300\text{ and }\sigma=\frac{35}{\sqrt[]{4}}=17.5[/tex]c) The probability that the mean score for the SRS is higher than 300 is:

[tex]\begin{gathered} Z=\frac{x-\mu}{\sigma} \\ Z=\frac{300-300}{17.5}=\frac{0}{17.5}=0 \end{gathered}[/tex][tex]P(Z>0)=1-P(Z\leq0)=1-0.5=0.5[/tex]The probability that the mean score for the SRS is higher than 335 is:

[tex]Z=\frac{335-300}{17.5}=2[/tex][tex]P(Z>2)=1-P(Z\leq2)=1-0.9772=0.0228[/tex]These results mean that it is a 50% of probability that the mean score of the SRS is greater than 300, and a 2.28% of probability that the mean score is greater than 335.

A fair die is rolled 4 times. What is the probability of having no 1 and no 3 among the rolls? Round your answer to three decimal places.

Answer:

66.667%

Step-by-step explanation:

In a fair die, there are 6 possible rolls. Out of the 6, 1 number is chosen each time. Since orde does not matter in this problem, we will be applying combination, so this would be written as 6C1 x 4. In order to exclude 3 and 4, from 6, the choices must be narrowed down to 4. Written out as an equation, this would be 4C1 x 4. To get the percentage, simply divide the two equations.

(4C1 x 4)/(6C1 x 4) = 0.66667 = 66.667%

riya won a LCD TV in amall raffle draw , the tv screen measures 16 inches in height and 12 inches in width. find the hypotenuse of the TV

Answer is 20” for the tv screen diagonal or hypotenuse

Step by step

Pythagorean theorem states

a^2 + b^2 = c^2

Solve for hypotenuse by substituting h & w for a and b and solve for c

16^2 + 12^2 = c^2

256 + 144 = c^2

400 = c^2

Take square root of both sides

20 = c

The tv screen diagonal = 20”

Step by step

Pythagorean theorem states

a^2 + b^2 = c^2

Solve for hypotenuse by substituting h & w for a and b and solve for c

16^2 + 12^2 = c^2

256 + 144 = c^2

400 = c^2

Take square root of both sides

20 = c

So far, Benny has run 3/2 miles, but that is only 2/5 of his total running distance. What is his total running

distance?

**Step-by-step explanation:**

this is 2/5 of his total.

4% of a number is what fraction of that number?

First, let's remember how we calculate a percentage:

If we call the number "x", 4% is calculated by dividing x by 100 and then multiplying by 4:

[tex]\frac{x}{100}\times4[/tex]This can also be represented as follows:

[tex]\frac{4}{100}\times x[/tex]Thus, 4% of a number is 4/100 of that number. We can still simplify this result as follows:

[tex]\frac{4}{100}=\frac{1}{25}[/tex]We divide 4 by 4 and get 1, and also divide 100 by 4 and get 25.

**Answer: 4% of a number is 1/25 of that number.**

If Angela spent $95 to buy 7 cakes for her office party, and she then cut each cake into **quarters** and each **quarter** into further 3 pieces, of which Kevin ate 5 pieces, then Angela had spent $5.65 on just the share of the cake that Kevin had.

As per the question statement, **Angela **spends $95 to buy 7 cakes for her office party, and she then cuts each cake into **quarters** and each **quarter** into further 3 pieces, of which Kevin ate 5 pieces.

We are required to calculate the **amount Angela **had spent on just the share of the cake that Kevin had.

To solve this question, first let us calculate the total number of pieces, did Angela cut all the 7 pieces of the cake into.

Considering one piece, that it was first cut into a **quarter** and then each **quarter** into further 3 pieces, one single piece out of original 7 pieces was cut into a total of [(4 * 3) = 12] pieces.

Therefore, all the 7 original pieces were altogether cut into a total of

[(7 * 12) = 84] pieces.

Now, since **Angela spent** $95 to buy the original 7 pieces,

Or, Angela actually spent $95 to buy 84 pieces of cake,

Then, 1 piece of the 84 costs $(95/84) = $1.13.

Now, since Kevin ate 5 such pieces of the 84, those 5 pieces cost

$(1.13 * 5) = $5.65.

Therefore, Angela had spent $5.65 on just the share of the cake that Kevin had.

**Total cost £5.**

**Step-by-step explanation:**

Let a hot dog cost £x and a portion of fry's cost £y.

Then:

8x + 12y = 48

Simplifying these 2 equations we get:
