what is the lateral area of a regular pyramid with a square base which has a slant height of nine units and base side length of seven units?
Answers
Answer:
126 sq units.
Step-by-step explanation:
We want the side surface area only, we'll calculate both
For the sides, we have 4 triangles with a base of 7 and a height of 9 units.
The area of a triangle is calculated with A = (b * h)/2
So, each of the sides of the pyramid has an area of:
A = (7 * 9) / 2 = 31.5 sq units
There are four sides, so total lateral area: 4 * 31.5 = 126 sq units.
The total lateral area of that pyramid is 126 sq units.
solve for y in 3(2y-4)=8y+9-9y
Answers
3(2y - 4) = 8y + 9 - 9y
Distribute 3:
6y - 12 = 8y + 9 - 9y
Combine like terms:
6y - 12 = -y + 9
Add y to both sides:
7y - 12 = 9
Add 12 to both sides:
7y = 21
Divide both sides by 3:
y = 3

What are the coordinates of A’ after reflecting across the line x = 3? (2, 3) (3, 2) (3, 4) (3, –2)
Answers
Answer:
A(3,4), B(2,2), C(6,3), D(1,6)
Step-by-step explanation:
The coordinates you wrote out are different then what is shown on the graph, On the graph the points are A(3,2), B(2,4), C(6,3), D(1,0)
So when it comes to solving this first you need to know what you are going to reflect over, in this case its X=3 which would be a horizontal at point 3 and across.
Then you count how far away the points are from X=3 line and reflect.
Hard to explain but i hope it helps
The coordinates of A after reflecting across the line x=3 is (2,3).
We can find the coordinates of a given graph using the following :The first number or the number which is located to the left side of a comma in the point is the x coordinate of the ordered pair.It represents the amount of movement along the x-axis from the origin.The movement to the right side of the number is positive and to the left side of the origin of the number is negative.The reflection of the point(x,y) across the line y=x is (y,x).The reflection of the point (x,y) across the line y=-x is (-y, -x).Hence, the correct answer is (2,3) if it is reflected across the line x=3.

There are 9 rows of 28 chairs set up for a play. A ticket to play costs $4. How much money will be made on ticket sales if all the seats are sold for the play?
Answers
First we have to determine how many chairs there are total. To do this multiply 9 by 28
9*28 = 252
That means you have a total of 252 chairs. Since we can assume that every person who buys a $4 ticket will only sit in one chair, we can say that if all the seats are filled then 252 people bought a ticket
To find the total price multiply the total chairs by the cost per ticket (or chair, which ever way you want to think of it as)
252 * 4 = 1008
You would make $1008

What is the slope of a line that is perpendicular to the line y = 1/6 x + 4?
Answers
-6
To find the slope of the perpendicular line, start with the original slope, 1/6.
The slope of a perpendicular line is the opposite and inverse of the slope of the original line. So, start by finding the inverse. This is done by simply flipping the numerator and the denominator to get 6/1, which is simplified to 6.
Finally, find the opposite of 6. You can find the opposite of a number by multiplying or dividing it by -1. If it is a positive number, just add a negative sign, and if it is already a negative number, take away the negative sign. So, the opposite of 6 is -6, which is out final answer.

Answer:

If the two events are disjoint, then P(A or B)=P(A)+P(B).
We were given that:
[tex]P(A)=\frac{4}{11}[/tex]
and
[tex]P(B)=\frac{3}{11}[/tex]
This implies that:
[tex]P(A\:or\:B)=\frac{4}{11}+\frac{3}{11}[/tex]

[tex]P(A\:or\:B)=\frac{7}{11}[/tex]

For overlapping events, you would subtract P(A and B) from the sum of P(A) and P(B).
In this case, you would do 4/11 + 3/11, which equals 7/11 minus 2/11, which equals 5/11.

HELP!!!! FAST!!! Which graph represents a reflection of f(x) = 2(0.4)x across the y-axis?
Answers
Answer: The correct option is A.
Explanation:
The given function is,
To find the graph of this function after the reflecting across y-axis, first we have to find the graph of the equation.
The value of the function is 2 when x=0, so, the graph of given equation intersect the y-axis at 2.
In the equation . Since , so the given function is decreasing function
The value of f(x) is always positive, so the graph of f(x) is always above the x-axis. Thus, the graph must be above the x-axis after reflection across y-axis.
So, the option (2) and (4) and incorrect.
When we reflect the graph across the y-axis then,
It means when x approaches to large negative number the f(x) approaches to 0 and when x approaches to large positive number the f(x) approaches to infinite.
Therefore, the correct option is show in first graph.

What is the range if times that the middle 50% of sophomores spend on homework per night?

Step-by-step explanation:
Another way of stating this problem is find the Interquartile Range which is
Quartile 3 - Quartile 1.
The middle 50% of times that sophomores spend on homework per night refers to the interquartile range in statistics. This is found by ordering the data from least to greatest, splitting the data into 4 equal parts, then finding the values at the 1st and 3rd quartiles. The IQR is the range between these two values.
Explanation:The range of times that the middle 50% of sophomores spend on homework per night refers to the interquartile range (IQR) in statistics. This is because the middle 50% is equivalent to the data between the 1st quartile (25th percentile) and the 3rd quartile (75th percentile). To determine this IQR, you must first have the data you need- in this case, how long each sophomore spends on their homework. Then, you must order this data from least to greatest. Once ordered, you find the 1st and 3rd quartile values by splitting the data into 4 equal parts. Your IQR is then the range between these two values.

By simplifying the given equation y + 8 = 4(x - 5) to y = 4x - 28 and substituting the points' coordinates, it is determined that Point B (5, 0) is the correct point that lies on the line described by the equation.
Explanation:To determine which point lies on the line described by the equation y + 8 = 4(x - 5), we need to verify which of the given options, when substituted into the equation, will satisfy it. First, we will simplify the equation to its standard line equation form y = mx + b (where m is the slope and b is the y-intercept):
y + 8 = 4(x - 5)y = 4x - 20 - 8y = 4x - 28Now we can substitute the x and y values from each of the points into this equation and check which one holds true.
Point A (-5, -8): Substitute x = -5 and y = -8.-8 = 4(-5) - 28-8 = -20 - 28 (Does not hold true)Point B (5, 0): Substitute x = 5 and y = 0.0 = 4(5) - 280 = 20 - 28 (Does hold true)Thus, Point B (5, 0) is the point that lies on the line described by the equation.

1. A given binomial distribution has a mean of 153.1 and a standard deviation of 18.2. Would a value of 187 be considered usual or
unusual? Why?
A. Unusual, because the result is less than the maximum usual value.
B. Usual, because the result is less than the minimum usual value.
C. Unusual, because the result is greater than the maximum usual value.
D. Usual, because the result is between the minimum and maximum usual values.
Answers
Answer:
Usual, because the result is between the minimum and maximum usual values.
Step-by-step explanation:
To identify if the value is usual or unusual we're going to use the Range rule of thumbs which states that most values should lie within 2 standard deviations of the mean. If the value lies outside those limits, we can tell that it's an unusual value.
Therefore:
Maximum usual value: μ + 2σ
Minimum usual value: μ - 2σ
In this case:
μ = 153.1
σ = 18.2
Therefore:
Maximum usual value: 189.5
Minimum usual value: 116.7
Therefore, the value of 187 lies within the limits. Therefore, the correct option is D. Usual, because the result is between the minimum and maximum usual values.
