Answer:

The game system that Jim bought had the sale of $55 off.

Step-by-step explanation:

Jim sale price = $195

Kaylen price = $250

250 -195 = 55

Since it’s $55 off, it was on sale for 22% off because 22% of $250 is 55 and 250-55= 195

taurus [48]

Answer:

Median = 15.80

Mode = 15.20\ \&\ 15.25

IQR = 2.35

Step-by-step explanation:

Given

15.60,\ 18.75,\ 14.60,\ 15.80,\ 14.35,

13.90,\ 17.50,\ 17.55,\ 13.80,\ 14.20,

19.05,\ 15.35,\ 15.20,\ 19.45,\ 15.95,

16.50,\ 16.30,\ 15.25,\ 15.05,\ 19.10,

15.20,\ 16.22,\ 17.75,\ 18.40,\ 15.25.

Solving (a): The median and the mode

First, we sort the data.

13.80,\ 13.90,\  14.20,\ 14.35,\ 14.60,\ 15.05,\ 15.20,\ 15.20,\ 15.25,\ 15.25,

15.35,\ 15.60,\ 15.80,\  15.95,\ 16.22,\ 16.30,\ 16.50,\ 17.50,\  17.55,\ 17.75,

18.40,\ 18.75,\ 19.05,\ 19.10,\ 19.45.

The median position is:

Median = \frac{n + 1}{2}th

Median = \frac{25 + 1}{2}

Median = \frac{26}{2}

Median = 13th

The 13th item is: 15.80

Hence:

Median = 15.80

The modes are:

Mode = 15.20\ \&\ 15.25 --- they both have frequency of 2 while others occur once

Solving (b): The interquartile range

This is calculated as:

IQR = Q_3 - Q_1

Since the median is at the 13th position, Q1 is:

Q_1 = \frac{1 + 13}{2}th

Q_1 = \frac{14}{2}th

Q_1 = 7th

The 7th item is: 15.20

Q_1 = 15.20

Similarly, Q3 is:

Q_3 = \frac{13+n}{2}

Q_3 = \frac{13+25}{2}

Q_3 = \frac{38}{2}

Q_3 = 19th

The 7th item is: 17.55

So:

Q_3 = 17.55

Hence,

IQR = 17.55 - 15.20

IQR = 2.35

The measures of the angles in a triangle are x, 2x, and 3x. The triangle is
nordsb [41]

Step-by-step explanation:

x + 2x + 3x = 180°

6x = 180°

Therefore, x = 30°

2 x = 60°

3x = 90°

Hence, it is a right angled triangle.

PLEASE HELP WITH MIDDLE SCHOOL MATH 1 Q THATS MULTIPLE CHOICE I NEED HELP PLEASE FOR BRAINLIEST*(08.06 MC)
Bess [88]
All you have to do is try out both of the equations with each of the different choices.

200 = 45 (3) + 20
200 = 135 + 20
200 = 155

200 = 35 (3) + 60
200 = 105 + 60
200 = 165
So, this one does not work.
--------------------------------------------
180 = 45 (3) + 20
180 = 135 + 20
180 = 155

180 = 35 (3) + 60
180 = 105 + 60
180 = 165
So, this one does not work.
----------------------------------------------
200 = 45 (4) + 20
200 = 180 + 20
200 = 200

200 = 35 (4) + 60
200 = 140 + 60
200 = 200
So this one works.

The answer would be C.

I hope this helps and I'm sorry it took so long!

Angles A and B are complementary. What is the value of x? 34 56 68 79
Lelu [443]

Answer: x = 34°


Explanation:


As per definition, complementary angles add up 90°.


In the figure you see angle A measures x + 22° and angle B measures x.


Therefore, according to the definition, you can set this equation:

       

             x + 22° + x = 90°


Solve for x:


  • start: x + 22 + x = 90
  • combine like terms: 2x + 22 = 90
  • subraction property: 2x = 90 - 22
  • do the operation: 2x = 68
  • division propery: x = 68/2
  • do the operation: x = 34

Answer: x = 34°
