 write a quadratic function that is three units write four units down and five times narrower then y=x squared
Answers
Answer:
y = 5(x - 3)^2 - 4 + c
Step-by-step explanation:
The standard form of a quadratic function is y = ax^2 + bx + c, where a, b, and c are constants. To shift the graph three units to the right and four units down, we can modify the constant term c and the linear term bx:
y = a(x - 3)^2 - 4 + c
To make it five times narrower, we can modify the coefficient of the squared term a:
y = (1/5)a(x - 3)^2 - 4 + c
Since we want the shape to be the same as y = x^2, we can set a = 5:
y = 5(x - 3)^2 - 4 + c
The value of c will depend on the specific context of the problem or graph.
A recent random survey of 100 individuals in Michigan found that 78 drove to work alone. A similar survey of 120 commuters in New York found that 58 drivers drove alone to work. Find the 95% confidence interval for the difference in proportions
Answers
The 95% confidence interval for the difference in proportions is approximately 0.0957 to 0.4977.
To find the 95% confidence interval for the difference in proportions between Michigan and New York commuters who drove alone to work, we can use the formula:
CI = (p1 - p2) ± Z * sqrt((p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2))
Where:
p1 and p2 are the proportions of Michigan and New York commuters who drove alone to work, respectively.
n1 and n2 are the sample sizes of Michigan and New York commuters, respectively.
Z is the critical value corresponding to the desired confidence level (95% confidence level has Z ≈ 1.96).
Given:
Michigan: p1 = 78/100 = 0.78, n1 = 100
New York: p2 = 58/120 = 0.4833, n2 = 120
Plugging in the values:
CI = (0.78 - 0.4833) ± 1.96 * sqrt((0.78 * (1 - 0.78) / 100) + (0.4833 * (1 - 0.4833) / 120))
CI = 0.2967 ± 1.96 * sqrt(0.006456 + 0.004074)
CI = 0.2967 ± 1.96 * sqrt(0.01053)
CI ≈ 0.2967 ± 1.96 * 0.1026
CI ≈ 0.2967 ± 0.201
The 95% confidence interval for the difference in proportions is approximately 0.0957 to 0.4977.

Suppose a jar contains 15 red marbles and 32 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.
Answers
The probability of drawing 2 red marbles is 0.081 or 8.1%.
There are 15 red marbles and 32 blue marbles, so there are 15+32=47 marbles total.
The probability of pulling a red marble on the first draw is 15/47.
If the first marble drawn is red, then there are 14 red marbles and 32 blue marbles remaining.
So, the probability of pulling a second red marble is 14/46.
To find the probability of both events happening, we multiply the probabilities:
P(both red) = P(first red) × P(second red | first red)
P(both red) = (15/47) × (14/46)
P(both red) = 0.081 (rounded to 3 decimal places)
Therefore, the probability of drawing 2 red marbles is approximately 0.081 or 8.1%.

The area and circumference of the circle with a radius of 8 inches are 200.96 square inches and 50.24 inches respectively.
What is the area and circumference of the circle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The area of a circle is expressed mathematically as;
A = πr²
The circumference of a circle is expressed as:
C = 2πr
Where r is radius and π is constant pi ( π = 3.14 )
Given that the radius of the circle is 8 inches.
Substituting this value into the formula, we get:
A = πr²
A = 3.14 × ( 8 in )²
A = 3.14 × 64 in²
A = 200.96 in²
Next, we calculate the circumference:
C = 2πr
C = 2 × 3.14 × 8 in
C = 50.24 in

B) Find the area of the plot land without the building and parking lot.
Answers
The perimeter of the plot land is 78.49 units and the area of the plot land without the building and parking lot is 210 square units
Finding the perimeter of the plot landFrom the graph, the vertices of the land are
A = (0, 20), B = (25, 19), C = (20, 2) and D = (5, 0)
Calculate the distance between adjacent vertices
So, we have
AB = √[(0 - 25)² + (20 - 19)²] = 25.02
BC = √[(20 - 25)² + (2 - 19)²] = 17.72
DC = √[(20 - 5)² + (2 - 0)²] = 15.13
AD = √[(0 - 5)² + (20 - 0)²] = 20.62
The perimeter of the plot land is
P = 25.02 + 17.72 + 15.13 + 20.62
P = 78.49 units
Finding the area of the plot landThis is calculated as
Area = Plot land - Building - Parking lot
Using the vertices, we have
Area = 1/2 * |0 * 19 + 25 * 2 + 20 * 0 + 5 * 20 - (20 * 25 + 19 * 20 + 2 * 5 + 0 * 0)| - [1/2 *(15 - 7 + 17 - 7) * (15 - 10)] - [(18 - 10) * (10 - 5)]

Answers
The trigonometric ratio in terms p are
cos 200 = -p
- sin 70 = -p.
To express each of the given trigonometric values in terms of p:
Since the cosine of 0° is equal to 1, we can say that cos 0° = p.
cos 200°: Using the identity
cos(180° + θ) = -cos(θ), we can rewrite
cos 200° = -cos(180° + 20°).
Since cos 20° = p, we can express cos 200° as -p.
sin(-70°): Using the identity
sin(-θ) = -sin(θ), we can rewrite
sin(-70°) as -sin(70°)
=- sin (90- 20)

Intelligence Iq scores are often reported to be normally distributed with u=100.0 and o=15.0. A random sample of 47 people is taken. What is the probability of a random person on the street having an IQ score of less than 96?
Answers
Given that the mean (μ) of IQ scores is 100 and the standard deviation (σ) is 15, we can convert the individual IQ scores into z-scores, which represent the number of standard deviations a particular IQ score is away from the mean.
The z-score can be calculated using the formula:
z = (x - μ) / σ
where x is the IQ score, μ is the mean, and σ is the standard deviation.
In this case, we want to find the probability of a random person having an IQ score less than 96. We need to find the z-score for an IQ score of 96 and then calculate the probability associated with that z-score using the standard normal distribution table.
First, calculate the z-score:
z = (96 - 100) / 15
z = -0.27
Next, we can use a standard normal distribution table or a calculator to find the probability associated with this z-score. The probability of a random person having an IQ score less than 96 is the area under the standard normal curve to the left of the z-score -0.27.
Using a standard normal distribution table or a calculator, the probability associated with a z-score of -0.27 is approximately 0.3944.
Therefore, the probability of a random person on the street having an IQ score of less than 96 is approximately 0.3944 or 39.44%.

The recursive formula of g(n) g(1) = -50 and g(n) = g(n-1) - 15
g(n) = g(n-1) - 15
Start with the given formula: G(n) = -50 - 15n
To find the recursive formula, we need to find the value of g(n) in terms of g(n-1).
To do this, we can subtract 15 from both sides of the equation:
G(n) - 15 = -50 - 15n - 15
Simplifying the equation, we get:
G(n) - 15 = -65 - 15n
Rearranging the equation, we get:
G(n) = -65 - 15n + 15
Now, we can substitute g(n-1) for -65 - 15n:
G(n) = g(n-1) - 15
Finally, we can find the value of g(1) by substituting n = 1 into the original equation:
G(1) = -50 - 15(1)
G(1) = -50 - 15
G(1) = -65

The volume of a triangular pyramid is 120 units cubed. If the base and height of the triangle that forms its base are 10 units and 6 units respectively, find the height of the pyramid.
Answers
The height of the pyramid is 12 units
To find the height of the pyramid, we need to use the formula for the volume of a pyramid,
V = (1/3) * B * h,
where V is the volume, B is the area of the base, and h is the height of the pyramid.
In this case, we know that the volume of the pyramid is 120 units cubed, and the base of the pyramid is a triangle with a base of 10 units and a height of 6 units.
Therefore, the area of the base is,
(1/2) * 10 * 6 = 30 square units.
Plugging these values into the formula for the volume of a pyramid, we get:
120 = (1/3) * 30 * h
Multiplying both sides by 3, we get:
360 = 30 * h
Dividing both sides by 30, we get:
h = 12
Therefore, the height of the pyramid is 12 units.

The conclusion can be determined from the dot plot is
The median of the data set is 10.
1. The number of observations is 10:
There are total 15 observations.
2. The median of the data set is 10.
From the dot plot the data is
9, 9, 9, 9, 9, 10, 10, 10, 10, 10, 10, 10, 11, 11, 11, 12
Thus, the median is 10.
3. Mean = Sum of observation / Total Number of observation
Mean = (9+9+9+9+9+10+10+10+10+10+10+11+11+11+12) /15
Mean= 150/15=10
Thus, the Mean is 10.
4. Range = 12 - 9
Range = 3.

Monique and two friends want to zip line through the mountains in the national park. Each person must rent zip gear which includes a harness, gloves and a helmet. They must also pay one experienced trainer to zip with them. If the total bill is for $70.25, how many hours did they zip line for? About how much did each person pay?
Answers
To find out how many hours they zip lined for, we need to subtract the cost of the gear and trainer from the total bill and then divide the remaining amount by the hourly rate.
Cost of gear per person:
Shoes: $10
Helmet: $3
Gloves: $2.50
Harness: $5.00
Total gear cost per person: $10 + $3 + $2.50 + $5.00 = $20.50
Total cost of gear for 3 people: $20.50 x 3 = $61.50
Cost of trainer: $15.00
Total bill (including gear and trainer): $70.25
Remaining amount for zip lining:
= $70.25 - $61.50 - $15.00
= $-6.25
Since the remaining amount is negative, it seems there might be an error in the calculation or information provided. The total bill should not be lower than the cost of gear and trainer.
However, if we assume the total bill is correct and there was an error in the calculation, we can proceed with finding out how many hours they zip lined for and how much each person paid.
Approximate number of hours:
Number of hours = Remaining amount / Hourly rate = $6.25 / $4.75 ≈ 1.32 hours
Approximate amount each person paid:
Amount each person paid
= Total bill / 3
= $70.25 / 3
≈ $23.42

The coordinates of the triangle A'B'C' after rotating triangle ABC 90 degrees clockwise are A'(3, 6), B'(3, 2), and C'(7, 4).
To rotate the points of a triangle 90 degrees clockwise, we can use the following formula for a 2D rotation:
x' = x cos(θ) + y sin(θ)
y' = -x sin(θ) + y cos(θ)
Let's apply this formula to each point of the triangle ABC:
For point A(-6, 3):
x' = -6 cos(90°) + 3 sin(90°) = -6 (0) + 3(1) = 3
y' = -(-6) sin(90°) + 3 cos(90°) = 6 (1) + 3 (0) = 6
So, point A' is (3, 6).
For point B(-2, 3):
x' = -2 cos(90°) + 3 sin(90°) = -2 .0 + 3. 1 = 3
y' = -(-2) sin(90°) + 3 cos(90°) = 2 .1 + 3 .0 = 2
So, point B' is (3, 2).
For point C(-4, 7):
x' = -4 cos(90°) + 7 sin(90°) = -4 .0 + 7 . 1 = 7
y' = -(-4) sin(90°) + 7 cos(90°) = 4.1 + 7 .0 = 4
So, point C' is (7, 4).
Therefore, the coordinates of the triangle A'B'C' after rotating triangle ABC 90 degrees clockwise are A'(3, 6), B'(3, 2), and C'(7, 4).

you are given f(x) = x + 3 and g(x) = 2x + 1
find g[g(-3)
find f[g(x)]
find g[f(x)]
Answers
Answer:
Step-by-step explanation:
f(x) = x + 3
g(x) = 2x + 1
g(g(-3)) = g(-5) = -9
f(g(x) = f(2x + 1) = 2x + 1 + 3 = 2x + 4
g(f(x) = g(x + 3) = 2(x + 3) + 1 = 2x + 7
