Priya asked each of five friends to attempt to throw a ball in a trash can until they succeeded. She recorded the number of unsuccessful attempts made by each friend as: 1, 8, 6, 2, 4. Priya made a mistake: The 8 in the data set should have been 18. How would changing the 8 to 18 affect the mean and median of the data set
Answer: The mean will increase and the median would not change
Step-by-step explanation:
Recorded data by Priya :
Data: 1,8,6,2,4
Mean of data = (1+8+6+2+4)/5
=21/5 = 4.2
Median of data = 1,2,4,6,8
Median = 4
Correct data: 1,18,6,2,4
Mean of data = (1+18+6+2+4)/5
=31/5 = 6.2
Median of data = 1,2,4,6,18
Median = 4
Therefore ; according to the evaluation above, the median will remain unchanged, but the mean increased from 4.20 to 6.20.
A total of 70 tickets were sold for a concert and earn the organizers $804. If the cost of each ticket is either $10 or $12, how many tickets of each type were sold?
Answer:
X=18
Y=52
Step-by-step explanation:
Let X represent the first type of ticket sold at the concert
Let Y represent the second type of ticket sold at the concert-----equation 1
X + Y= 70 (Total number of tickets sold) ------equation 2
(X×10) + ( Y×12)=$804. ( Total money generated in the concert
Since,
X+Y= 70
X= 70-Y
Substitute (70-Y) for X in equation 2
(70-Y)×10 + Y×12=804
700-10Y+12Y= 804
Collect the like terms
700+2Y=804
2Y=804-700
2Y= 104
Divide both sides by the coefficient of Y which is 2
2Y/2= 104/2
Y=52
Substitute 52 for Y in equation 1
X+Y=70
X+ 52=70
collect the like terms
X= 70-52
X=18
Hence the first type of ticket sold is 18 tickets and the second type of ticket sold is 52 tickets.
suppose that the current canadian dollar to US dollar exchange rate is 0.80 CAD = $1 US and that the U.S. dollar price of an Apple iphone is $320 what is the Candian dollar price of iphone?
Answer: 256 CAD
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the price in US dollars of the iphone (320) and multiply it by 0.80 ( Canadian dollar to US dollar exchange rate)
Mathematically speaking:
Since:
$1 US = 0.80 CAD
$320 x0.80 = 256 CAD

Dorinda worked 2 part- time jobs and earned $234.50 for working a total of 30 hours at both jobs. She is paid $7.50 per hour at Job A and $8.00 per hour at Job B. How many hours did Dorinda work at Job A?
Answer:
Dorinda worked at Job A for 11 hours
Step-by-step explanation:
Step one
This is a word that leads to simultaneous.
Let us begin by modeling the system of equation from the problem
Let x and y be the number of hours worked in both jobs A and B respectively
Step two
x+y=30---------1
7.5x+8y=234.50----2
Solving the equations simultaneously we have
1. Multiplying equation 1 by 8 and equation 2 by 1 and subtracting from equation 2 to find y
8x+8y=240---------1
- 7.5x+8y=234.50----2
=0.5x=5.5
x=5.5/0.5
x= 11hrs
Substituting x=11 in equation 1 we can find y
11+y=30
y= 30-11
y= 19hrs

What is the value of X very easy
Answer:
x=36
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
Therefore,
x+65+79=180
Add 65 and 79
x+144=180
We want to solve for x. In order to do this, we have to get x by itself. 144 is being added to x (+144)The opposite of addition is subtraction, so subtract 144 from both sides(-144)The +144 and -144 will cancel out, and leave x by itself.
x+144-144=180-144
x=180-144
x=36
Let’s check our answer. Add all the angles together, and make sure they equal 180 degrees.
x+65+79
We know x is equal to 36, so we can substitute it in
36+65+79
180
The 3 angles add to 180, so we know that x=36

The data set below shows prices for concert tickets in 10 major cities. Find the interquartile range (IQR) of the set. How do the middle 50% of the prices vary?
Answer: IQR = 16
Step-by-step explanation:
Given the following data:
Cost of concert :
CITY : Q, R, S, T, U, V, W, X, Y, Z
Price : 35,36,42,38, 24,29,25, 44,49, 26
Interquartile range (IQR) = Q3 - Q1
Where,
Q3 = the upper quartile
Q1 = lower quartile
Rearranging the data:
24,25,26,29,35,36,38,42,44,49
Q3 = 42
Q1 = 26
IQR = (42 - 26) = 16

a is adjacent, bis opposite, c is the hypotenuse
Y
N
I don’t know the answer! Someone please tell me
Answer:
a is adjacent, b is opposite, c is the hypotenuse
Step-by-step explanation:
A right angled triangle must contain the opposite, the adjacent and the hypotenuse. The opposite is the side that directly faces the angle of interest. The adjacent is the side that is close to the angle of interest.
Given that the angle Y is positioned between X and Z, the point b becomes the opposite of Y. The point a becomes adjacent to angle Y while c remains the hypotenuse of the right angled triangle.
The image below typifies the explanation given above. It shows the relationship between the three sides of the right angled triangle in detail.

a is adjacent, b is opposite, c is the hypotenuse

What transformations would result in the image shown? (question for the first image)
a.Δ ABC is reflected over both axes.
b.Δ ABC is reflected over the y-axis and translated down 5 units.
c.Δ ABC is reflected over the x-axis and translated right 5 units.
d.Δ ABC is translated right 5 units and down 5 units.
Which transformations would result in the image shown?
a.ABCD is reflected over both axes.
b.ABCD is translated right 4 units and down 3 units.
c.ABCD is reflected over the x-axis and translated right 4 units.
d.ABCD is reflected over the y-axis and translated down 3 units.
Answer: For the first image, D will be the correct answer. For the second image, A will be the correct answer.
Step-by-step explanation:
The first image has a quite simple answer because translating the shape just means moving every point in the direction given according to some many units. In this case, we would be translating points A(-4,3), B(-3,1), and C(-1,2) 5 units right and 5 units down to get us the prime points of A'(1,-2), B'(2,-4), C'(4,-3).
In the second image, a reflection just describes a flip over some line, known as the line of reflection. We change the point's signs depending on the line of symmetry we are given when reflecting (in this case, the y axis). Reflecting the trapezoid over the y axis will result in a change of signs of the x values of the given points. Point A of the trapezoid is located on coordinate (-2,2), after the reflection, it will be located on point (2,2). Points B will reflect from point (-1,2) to point (1,2). Point C will reflect from (-1,1) to (1,1). Finally, point D will reflect from point (-3,1) to (3,1). After this reflection, we have to perform the same one except only the y values of our coordinates will change because we are reflecting over the x axis. After you graph the trapezoid from the previous reflection, do the same thing by just changing the y values of the coordinates to get your desired image.

You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.
Answer:
percentage error = 39.1%
Step-by-step explanation:
You estimate that there are 64 marbles in a jar. The actual amount is 46 marbles. Find the percent error. Round to the nearest tenth of a percent if necessary.
Given that You estimate that there are 64 marbles in a jar.
The actual amount is 46 marbles
Actual marbles = 46
Your estimate = 64
[tex]\% error =\frac{estimated - actual}{actual}[/tex]
% error = | estimate - actual | / actual × 100%
estimate amount - actual amount = 64 - 46 = 18
[tex]= \frac{18}{46} \times 100\\\\=0.391\times 100\\\\=39.1 \%[/tex]
Therefore, percentage error = 39.1%
