For a normal distribution with a mean of 68 and a standard deviation of 9, the percentage of scores less than 50 is 2.28%.

It is given that scores on a psychology exam have a normal distribution with a mean of 68 and a standard deviation of 9. The percentage of scores less than 50 can be determined as follows.

1. Calculate the z-score for 50 using the formula:

z = (X - μ) / σ

where

X = 50 (the value we're comparing to)

μ = 68 (mean)

σ = 9 (standard deviation)

2. Plug in the values:

z = (50 - 68) / 9 = -18 / 9 = -2

3. Use a z-table or calculator to find the area to the left of z = -2. This represents the percentage of scores less than 50.

4. Based on the z-table or calculator, the area to the left of z = -2 is approximately 0.0228, which means that around 2.28% of scores were less than 50.

So, about 2.28% of scores on the psychology exam were less than 50.

Let's denote the cost of one apple as 'a' and the cost of one banana as 'b'. We can set up a system of two equations to represent the given information:

4a + 9b = 12.70   (equation 1)

8a + b = 17.70    (equation 2)

We can use either substitution or elimination method to solve for 'a' or 'b'. Let's use the elimination method by multiplying equation 2 by 9 and subtracting it from equation 1:

4a + 9b = 12.70

-(72a + 9b = 159.30)   (multiplying equation 2 by 9)

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

-68a = -146.60

The p-value for this hypothesis test is approximately 0.1317.

To calculate the p-value for the hypothesis test, we need to perform a one-sample proportion test using the sample data provided.

Let's define the null and alternative hypotheses:

Null hypothesis (H₀): The proportion of Marriott customers carrying two Wi-Fi devices is equal to or less than 0.60.

Alternative hypothesis (H₁): The proportion of Marriott customers carrying two Wi-Fi devices exceeds 0.60.

Sample size (n) = 120

Number of customers with two Wi-Fi devices (x) = 78

To test the hypothesis, we can use the normal approximation to the binomial distribution since the sample size is reasonably large.

First, calculate the sample proportion:

[tex]\hat{p}[/tex] = x / n = 78 / 120 = 0.65

Next, calculate the test statistic (z-score):

z = [tex]\frac{\hat{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }[/tex]

= (0.65 - 0.60) / √((0.60 * (1 - 0.60)) / 120)

= 0.05 / √(0.24 / 120)

= 1.1180

Now, we can find the p-value corresponding to the calculated test statistic using a standard normal distribution table or a statistical calculator.

In this case, the p-value for a one-sided test (since we are testing if the proportion exceeds 0.60) is approximately 0.1317.

Therefore, the p-value for this hypothesis test is approximately 0.1317.

p + q + 36 = 0 is the equation that is true. From this equation, we can say that p + q = -36.

If we substitute x = 1 in the given function, we get:

f(1) = [tex](1)^4 + 5(1)^3 + p(1)^2 + q(1) + 30[/tex]

= 1 + 5 + p + q + 30

= p + q + 36

We are given that f(1) = 0. Therefore, we have:

p + q + 36 = 0

This is the equation that is true. From this equation, we can say that p + q = -36.

Now, let's see why this is the case. When we substitute x = 1 in the given function and get f(1) = 0, it means that (1, 0) is a point on the graph of the function. This point lies on the x-axis, which means that the function intersects the x-axis at x = 1. Since the x-axis is the line y = 0, this means that f(x) = 0 when x = 1.

Using this information, we can write an equation in terms of p and q. If we substitute x = 1 in the given function and get f(1) = 0, it means that:

f(x) = [tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q))[/tex]

Therefore, we have:

[tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q)) = 0[/tex]

Since (1,0) is a point on the graph of the function, we know that x = 1 is a root of this equation. Therefore, we have:

[tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q)) = (x - 1)(x^2 + (7+p)x + (36-p-q))[/tex]

We know that (x - 1) is a factor of this equation, so we can use polynomial long division to divide the expression [tex](x^2 + (7+p)x + (36-p-q))[/tex] by (x - 1). The quotient will give us the other two roots of the equation. However, we do not need to find these roots to answer the question. All we need to know is that p + q = -36.

Based on experimental probability, Abdul should expect 10 tails in the next 40 flips.

The experimental probability of getting tails is calculated as the ratio of the number of tails obtained in the experiment to the total number of coin flips.

In this case, the experimental probability of getting tails is 16/64, which simplifies to 1/4 or 0.25.

This means that in the long run, we would expect approximately 25% of coin flips to result in tails.

To determine how many of the next 40 flips Abdul should expect to come up tails based on experimental probability,

we can multiply the experimental probability by the total number of flips.

Abdul should expect 0.25 × 40 = 10 tails in the next 40 flips.

Experimental probability of getting tails = Number of tails obtained / Total number of coin flips

Experimental probability of getting tails = 16/64

Experimental probability of getting tails = 0.25 or 25%

Step-by-step explanation:

The coordinates of point B: (0,6)

Coordinates of point C: (3,8)

A kite has 4 sides, of which we have 2 equal pairs, thus the coordinates of point D must be (6,6)

Answer:

(6,6)

Step-by-step explanation:

The question is asking us to complete the half figure, and make it a kite.  We can see that the 2 lines AB and BC are half of the shape.  In the attachment, I drew a line of symmetry down the middle of the shape.  

I also created a point, Y, down the red line, AC, to represent the perpendicular bisector of the 2 diagonals.  We can see that line segment BY is the radius of the entire line BD.  

This radius is 3 units, so we now know that the diameter horizontally is 6 units.  We can draw this on the other side to create point D.  

This means that point D is at (6,6).

The height of the given trapezoid-shaped tabletop is 75.5 centimeters.

The height of the trapezoid-shaped tabletop. To calculate the height, we can use the formula for the area of a trapezoid: A = (1/2)(b1 + b2)h, where A is the area, b1 and b2 are the lengths of the bases, and h is the height.

Given the area (A) is 7,701 square centimeters, the longer base (b1) measures 119 centimeters, and the shorter base (b2) is 85 centimeters, we can solve for the height (h) using the following steps:

1. Plug in the given values into the formula: 7,701 = (1/2)(119 + 85)h
2. Simplify the expression inside the parentheses: 7,701 = (1/2)(204)h
3. Multiply the two numbers inside the parentheses: 7,701 = 102h
4. Divide both sides of the equation by 102 to solve for h: h = 7,701 / 102
5. Calculate the value of h: h ≈ 75.5 centimeters

So, the height of the trapezoid-shaped tabletop is approximately 75.5 centimeters.

Answer: 9 x 10^4

Step-by-step explanation:

9 ten thousands in standard form is written like this: 90,000

To convert this into scientific notation, we simply count how many spaces we want to move the decimal point.

So far, our number looks like this with a decimal point: 90000.0

To make this number equal to 9, we have to move the decimal point 4 spaces to the left.

The 4 then becomes our exponent.

So now we have 9 by itself, and all we do is multiply it by 10 with an exponent of 4, to show you are multiplying 10 four times.

Therefore, 9 ten thousands written in scientific notation is 9 x 10^4

Step-by-step explanation:

Let's assume that the length of the rectangle is x and the width is y.

The perimeter of the rectangle is given by:

P = 2x + 2y

Substituting P = 62, we get:

62 = 2x + 2y

Simplifying the above equation, we get:

x + y = 31

The area of the rectangle is given by:

A = xy

To find the area, we need to solve for one of the variables, either x or y. We can use the equation x + y = 31 to solve for y in terms of x:

y = 31 - x

Substituting this expression for y in the equation for the area, we get:

A = x(31 - x)

Expanding the above expression, we get:

A = 31x - x^2

To find the maximum area, we need to find the value of x that maximizes A. We can do this by completing the square:

A = - (x^2 - 31x)

A = - [(x - 15.5)^2 - 240.25]

A = 240.25 - (x - 15.5)^2

The maximum area occurs when x = 15.5, so the dimensions of the rectangle are:

x = 15.5 mm

y = 31 - x = 15.5 mm

The area of the rectangle is:

A = xy = 15.5 mm × 15.5 mm = 240.25 mm^2

Therefore, the area of the rectangle is 240.25 square millimeters.

"The probability that the first freshman to arrive will be seated at a round table is (5/13)."

To calculate the probability, we need to determine the total number of seats and the number of seats at round tables.

There are 8 rectangular tables with 6 chairs each, so the total number of seats at rectangular tables is 8 * 6 = 48.

There are 5 round tables with 4 chairs each, so the total number of seats at round tables is 5 * 4 = 20.

The total number of seats in the community center is 48 + 20 = 68.

The probability of the first freshman being seated at a round table is the number of seats at round tables (20) divided by the total number of seats (68), which gives us 20/68 = 5/17.

Therefore, the correct answer is option C: 5/17.

The incorrect statement about the intersecting triangles is A. CG ≅ FG.

With intersecting triangles, it is not always guaranteed that segments like CG and FG will be congruent. The lengths of CG and FG will depend on the specific configuration of the chords and their intersection point G.

However, CE/EG = FD/DG statement is TRUE. This is a consequence of the Intersecting Chords Theorem. When two chords intersect inside a circle, the products of their segments are equal.

Since ∠CEG ≅ ∠FDG intersect inside a circle, the corresponding intercepted arcs create equal angles at the intersection point. Therefore the statement is true.

ΔCEG ~ ΔFDG is also true because we know that the triangles share an angle and have proportional sides.

Using Pythagorean theorem the distance between the school and the fire station is approximately 4.7 miles, while the distance between the school and the hospital is approximately 7.8 miles.

To solve this problem, we can use the Pythagorean theorem to find the distances and then add them up to get the total distance between the school and the fire station, and then between the school and the hospital.

Part A:

Let's call the middle school point A, Town Hall point B, and the fire station point C. We can draw a right triangle with AB as the base, BC as the height, and AC as the hypotenuse. Using the Pythagorean theorem, we have:

AC^2 = AB^2 + BC^2

AC^2 = 4.3^2 + 1.7^2

AC^2 = 18.98 + 2.89

AC^2 = 21.87

AC ≈ 4.7 miles (rounded to the nearest tenth)

Therefore, the length of the straight line between the school and the fire station is approximately 4.7 miles.

Part B:

Let's call the hospital point D. We can draw another right triangle with CD as the base, BC as the height, and BD as the hypotenuse. Using the Pythagorean theorem, we have:

BD^2 = BC^2 + CD^2

BD^2 = 1.7^2 + 3.1^2

BD^2 = 2.89 + 9.61

BD^2 = 12.5

BD ≈ 3.5 miles (rounded to the nearest tenth)

Now, we can add the distance between A and B (4.3 miles) to the distance between B and D (3.5 miles) to get the total distance between A and D:

AD ≈ 7.8 miles (rounded to the nearest tenth)

Therefore, the length of the straight line between the school and the hospital is approximately 7.8 miles.

3x + 5($6.70 - 2x) = $12.85

Now, solve for x:

3x + $33.50 - 10x = $12.85

Combine like terms:

-7x = -$20.65

Now, divide by -7:

x = $2.95

Now that we know the cost of a spiral notebook, we can plug this value back into the expression we found for y:

y = $6.70 - 2($2.95)

y = $6.70 - $5.90

y = $0.80

So, the cost of each folder is $0.80.
