Write three different pairs of coordinate points that form a line segment with a slope greater than 2.

The number of sets to be printed to ascertain at least 4 identical subset is there on the list when a computer is printing out subsets of a 5 element set is 97.

The total number of subset for a n element set is 2^{n}. Therefore, for a 5 element set is 2^{5} = 32.

Thus to ensure there are at least 4 identical subset, the computer should print 3 times the total number of subsets possible plus 1 additional subset, i.e. 3×32 + 1 = 97.

-- The question is incomplete, the correct question is as follows --

The symbols p,x, and s represent sample statistics.

- p (pronounced "p-hat") is the sample proportion. It is used to estimate the population proportion. It is computed as the number of successes in the sample divided by the sample size.

-x (pronounced "x-bar") is the sample mean. It is used to estimate the population mean. It is computed as the sum of all the values in the sample divided by the sample size.

- s is the sample standard deviation. It is used to estimate the population standard deviation. It measures how spread out the data is in the sample. It is computed as the square root of the sum of the squared deviations from the sample mean divided by the sample size minus one.

These sample statistics are used to make inferences about the corresponding population parameters, which are denoted by Greek letters such as μ (mu) for the population mean and σ (sigma) for the population standard deviation.

Answer:

x = 2, y = 3

Step-by-step explanation:

x + y = 5

Shift y to the other side and change to (-y).

x = 5 - y  --- Equation 1

x - 2y = -4 --- Equation 2

Substitute x = 5 - y into Equation 2:

x - 2y = -4

5 - y - 2y = -4

Shift 5 to the other side and change to (-5).

-y - 2y = -4 - 5

Evaluate like terms.

-3y = -9

Divide both sides by -3.

y = -9 ÷ -3

y = 3

Substitute y = 3 into Equation 1:

In determining automobile-mileage ratings, the probability calculations for specific events regarding mpg (miles per gallon) of a certain model with a mean of 33 mpg and a standard deviation of 1.7 mpg will be determined using Excel.

a. P(X<30):

To calculate the probability that the mpg (X) is less than 30, we need to find the cumulative probability up to 30 using the normal distribution function in Excel. The formula in Excel would be "=NORM.DIST(30, 33, 1.7, TRUE)". Evaluating this formula will give the desired probability.

b. P(28<X<35):

To calculate the probability that the mpg (X) falls between 28 and 35, we need to find the cumulative probability up to 35 and subtract the cumulative probability up to 28. The formula in Excel would be

"=NORM.DIST(35, 33, 1.7, TRUE) - NORM.DIST(28, 33, 1.7, TRUE)".

d. P(X>31):

To calculate the probability that the mpg (X) is greater than 31, we need to find the cumulative probability starting from 31 using the complement of the normal distribution function in Excel. The formula in Excel would be

"=1 - NORM.DIST(31, 33, 1.7, TRUE)".

e. Mileage rating for upper 5%:

To find the mileage rating that the upper 5% of cars achieve, we need to find the value of mpg (X) for which the cumulative probability is 95%. Using the inverse of the normal distribution function in Excel, the formula would be

"=NORM.INV(0.95, 33, 1.7)".

By evaluating the respective formulas in Excel, the probabilities and the mileage rating can be calculated accurately.

Here is the complete question:

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs $3.25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most $30 before tax. The restaurant only sells pancakes in stacks of 4 pancakes for $5.50 . Let S represent the number of stacks of pancakes that Benjamin buys. What is the largest number of pancakes that Benjamin can afford?

Given:

Cost of chocolate milk = $3.25

Maximum bill that Benjamin wants before tax = $30

Cost of stack of 4 pancakes = $5.50

Let S be the number of stacks of pancakes that Benjamin buys

Solution:

Cost per stack of pancakes = $5.50  

Cost of S number of stacks of pancakes = S*5.50  = 5.50 S

So benjamin will spend money on 1 chocolate milk and S number of stacks of pancakes

Compute the total money spent by Benjamin:

Cost of chocolate milk + cost per stack of pancakes = 3.25 + 5.50 S

Maximum bill that Benjamin wants is $30 So,

The total money should be less than equal to the maximum bill that benjamin wants i.e. less than or equal to 30. So it is represented as:

3.25 + 5.50S ≤ 30  ----- (1)

Now using (1) we can find the largest number of pancakes that  Benjamin can afford :

3.25 + 5.50S ≤ 30

5.50S ≤ 30 - 3.25    

subtract 3.25 from 30

5.50S ≤ 26.75

Divide by 5.50

S ≤ 4.863636

S ≤ 4.86

S≤ 4 approx

Since the restaurant only sells pancakes in stacks of 4 pancakes so,

4 stacks = 4 *4 =  16

So the largest number of pancakes that Benjamin can afford are 16.

If we do not round off the the value stacks then we get:

4.86 stacks = 4.86 *4 =  19.44 pancakes

So the largest number of pancakes that Benjamin can afford are 19

Answer:

Surface Area = 85.75 ft²

Step-by-step explanation:

Surface area of pyramid = ½(Perimeter of triangular base * slant height of pyramid) + Area of triangular base

Perimeter of triangular base = sum of all sides of the triangular base = 5+5+5 = 15 ft

Slant height of pyramid = 10 ft

Area of triangular base = ½*base of triangle*height of triangle = ½*5*4.3 = 10.75 ft²

Plug in the above values:

Surface Area = ½(15*10) + 10.75

= (15*5) + 10.75

= 75 + 10.75

Surface Area = 85.75 ft²

Step-by-step explanation:

first of all we need to understand the given information.

2 shapes are similar, when they have the same angles, AND when every pair of corresponding sides (or side lengths) or any other lines like heights or diagonals has the same scaling factor.

A B/X Y = 4 is the scaling factor.

it means that the large side A B is 4 times a long as the corresponding short side X Y in the pair A B, X Y.

and the same goes for e.g. B C/Y Z and all the other side or length pairs - every ratio is 4.

so, in fact, to get the measurements of the small shape we need to multiply the measurements of the large shape by 1/4.

it is not given information, but I assume it is a symmetric hexagon with A B = E D, A F = F E = B C = C D.

and as both hexagons are similar, the same applies to the corresponding sides in the small hexagon.

for the area of ABCDEF we can split the hexagon into 2 equal trapezoids ABCF and EDCF.

the area of such a symmetrical trapezoid is

(baseline + topline)/2 × height

baseline = C F = 10 cm

topline = A B = 5 cm

height = A E/2 = 12/2 = 6 cm

so, the area of the whole hexagon is

ABCDEF = 2×(10+5)/2 × 6 = 15 × 6 = 90 cm²

W Z = C F × 1/4 = 10/4 = 2.5 cm

U V = X Y = A B × 1/4 = 5/4 = 1.25 cm

U Y = A E × 1/4 = 12/4 = 3 cm

the height of a small trapezoid is then U Y/2 = 3/2 = 1.5 cm

to get the shaded area we need to calculate the area of the small hexagon and subtract it from the area of the large hexagon :

UVWXYZ = 2×(2.5 + 1.25)/2 × 1.5 = 3.75 × 1.5 = 5.625 cm²

so, the shaded area is

90 - 5.625 = 84.375 cm² ≈ 84.38 cm²

Step-by-step explanation:

During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.

12 hours = 9 inches of snow

1 hour = x

Cross Multiply

12 hours × x = 1 hour × 9 inches

x = 9/12

x = 0.75 inches

Therefore, 0.75 inches of snow fell at each hour.

The probability that a truck drives between 122 and 127 miles in a day is 0.0165, rounded to four decimal places.

To find the probability that a truck drives between 122 and 127 miles in a day, we'll use the z-score formula and standard normal distribution table. Follow these steps:

Step 1: Calculate the z-scores for 122 and 127 miles.
z = (X - μ) / σ

For 122 miles:
z1 = (122 - 90) / 18
z1 = 32 / 18
z1 ≈ 1.78

For 127 miles:
z2 = (127 - 90) / 18
z2 = 37 / 18
z2 ≈ 2.06

Step 2: Use the standard normal distribution table to find the probabilities for z1 and z2.
P(z1) ≈ 0.9625
P(z2) ≈ 0.9803

Step 3: Calculate the probability of a truck driving between 122 and 127 miles.
P(122 ≤ X ≤ 127) = P(z2) - P(z1)
P(122 ≤ X ≤ 127) = 0.9803 - 0.9625
P(122 ≤ X ≤ 127) ≈ 0.0178

So, the probability that a truck drives between 122 and 127 miles in a day is approximately 0.0178 or 1.78%.

For a card game with a pack of total 52 cards, where success is that drawn card is face card. The excepted value for this game is - 0.615.

In probability theory, Expected Value is the estimated gain or loss in partaking in an event many times. It is calculated by the formula written as \(E(X) = \sum P(X) × X \)

where, X is the number of trials and

In other words, sum of multiplication of probability of gain to gain amount and multiplication of probability of loss to loosing amount. We have a experiment card game. There is a total 52 card deck. Let's consider an event X that one card is drawn from 52.

Number of face cards in pack of 52 = 3× 4 = 12

Number of non- face cards in pack of 52 = 52 - 12 = 40

Probability that drawn card is face card or probability of success = 12/52 = \( \frac{ 3}{13}\)

Probability that drawn card is not face card or probability of loss = \( \frac{40}{52} = \frac{10}{13} \)

winning amount on probability of success= $4

So, excepted value = \(4 \times \frac{3}{13} - 2 \times \frac{10}{13} \)

= \( - \frac{8}{13} \) = - 0.615

Hence, required value is - 0.615.
