From the given frequency table,
Frequency represents the number of people who made the calls.
Total number of people who made the calls = 16 + 11 + 5 + 3 + 1
= 36
Number of people who made less than 13 calls = 16 + 11 + 5
= 32
Number of people who made at least 9 calls = 5 + 3 + 1
= 9
Percentage of people who made at least 9 calls = [tex]\frac{\text{Number of people who made at least 9 calls}}{\text{Number of people who made the calls}}\times 100[/tex]
= [tex]\frac{9}{36}\times 100[/tex]
= 25%
Difference in the number of people who made the calls between 5-8 calls than 13-16 calls = 11 - 3 = 8

Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answer:
(-4,9)
Step-by-step explanation:
substitute the given value for y into the first equation
x-5(-2x+1)=-49
distribute
x+10x-5=-49
add like terms
11x-5=-49
add 5 to both sides
11x=-44
divide both sides by 11
x=-4
now plug x into into the second equation
y=-2(-4)+1
y=8+1
add like terms

What single transformation was applied to triangle A to get triangle B?
Answer:
should be reflection
Step-by-step explanation:
bc a translation would just move it and rotation and dilation wouldn't work either
The single transformation was applied to triangle A to get triangle B is a reflection, in which A is reflected around the y-axis.
What is reflection?Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point.
Given:
The triangles A and B are shown in the given figure,
Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original,
Rotation is the process of going around a center.
A shape is translated when it is moved up, down, left, or right without turning. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes.
Thus, triangle A is reflected as B.

Two points in the (x, y) plane are a distance of 5 units apart. After a certain transformation is applied to both points, the two new points are 10 units apart. What was the transformation?
Answer:
translation
Step-by-step explanation:
Based on the information provided the type of transformation would have been a translation of one or both points. This means that either one or both points were moved. If only one point was moved it would have moved 5 units. If both were moved equally then they would have moved 2.5 units apart. Since we are not told the initial and end values of each point we cannot tell if the translation was a vertical or horizontal translation.

What is the complex conjugate of the root x = 3i
Answer:
For example, the conjugate of 0 + √3 is 0 - √3, the conjugate of -√3 is √3, and the conjugate of 2 - 5√3 is 2 + 5√3.
Step-by-step explanation:
The complex conjugate of the root x = 3i will be x = -3i.
What is complex conjugate?The complex conjugate of a complex number is the number that has equal real and imaginary parts that are opposite in sign but equal in magnitude.
A given complex function is x = 3i
As we know that the complex conjugate function is one in which the imaginary part of the function becomes negative.
The complex conjugate function will be:-
x = -3i
Therefore the complex conjugate of the root x = 3i will be x = -3i.

Step-by-step explanation:
Every autumn, the North American Monarch
butterfly migrates up to 3,000 miles to California and Mexico where it hibernates
until early spring. The butterfly travels on average 50 miles per day.
Part A
The equation is d = 50t
This is because the slope of 50 represents how many miles per day the butterflies cover (on average). The y intercept is 0 to indicate that 0 miles have been traveled initially.
You can think of this as the equation y = 50x
If t = 1, then d = 50t = 50*1 = 50 miles have been covered
If t = 2, then d = 50t = 50*2 = 100 miles have been covered
And so on.
==========================================================
Part B
You'll have these values in the bottom row (in the order presented): 50, 100, 150, 200, 250
You can plug in the values t = 1, t = 2, t = 3, t = 4 and t = 5 into d = 50t to find those answers in bold.
Or you could add on 50 each time to generate each new value. We start at 50 since t = 1 corresponds to d = 50.
==========================================================
Part C
You can keep the pattern of 50,100,150, ... going until you reach 2500. Then note the t value that pairs with d = 2500
In my opinion, that's the slower method.
The quicker method is to plug d = 2500 into the equation for part A, and then solve for t.
d = 50t
2500 = 50t
50t = 2500
50t/50 = 2500/50 ....... divide both sides by 50
t = 50
It will take 50 days for the average distance traveled to be 2500 miles.

HELP!! Identify the transformation from ABC to A'B'C'.
1. Reflection over the y-axis
2. 90 degree rotation
3. 270 degree rotation
4. Reflection over the x-axis
Answer:
Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.
Choice 1.
Step-by-step explanation:
Reflection over the x-axis
Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).
The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)
Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.
Choice 1.
Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 2, and the given zeros. -4,0,2,4
Answer:
A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;
f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x
Step-by-step explanation:
The given parameters of the polynomial are;
The leading coefficient of the polynomial = 2
The zeros of the polynomial = -4, 0, 2, 4
We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)
For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'
To have a leading coefficient of 2, we can add '2' as a factor of the polynomial
Therefore, we can have the factors of the polynomial as follows;
(x² - 4²)·2·x×(x - 2) = 0
From the above equation, using a graphing calculator, we get the following possible polynomial;
(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0
Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.

A cyclist rides a distance of 36 km at an average speed of 16 km/h.
Calculate the time taken to complete this ride. Give your answer in hours and minutes.
Please Help!
Answer:
2.25 hours, or 2 hours and 15 minutes.
Step-by-step explanation:
All we do is 36/16 which is 2.25. 0.25 or 1/4 of an hour is 15 minutes. So, your answer is 2 hours and 15 minutes.
It takes 2 hour and 12 minutes for the cyclist to complete the ride of 36km distance.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Total distance covered by cyclist= 36km
Average speed of the cyclist = 16km/hr
Therefore, using unitary method:
16 km distance takes time = 1hr
Therefore, 1 km distance takes time =(1/16)hr
Therefore, 36 km distance takes time = (1/16)×36 hr
=(1/4)×9 hr
=9/4 hr
=2.25 hr
=(2+0.25)hr
=2hr+0.25hr
=2hr+0.25×60minutes
=2hr and 15 minutes.
Hence, it takes 2hr and 15 minutes for the cyclist to complete 36 km rides.
