Answer:
∠1 + ∠2 + ∠3 = 180°
Step-by-step explanation:
Given : AB II XC
To Show : ∠1 + ∠2 + ∠3 = 180°
Proof: Here, given that AB is parallel to the line XC
⇒ ∠4 = ∠2 (Pair of Alternate angles as AB II XC) ......... (1)
and ∠5 = ∠3 (Pair of Alternate angles as AB II XC) ........... (2)
Now, ∠1 + ∠4 + ∠5 = 180° ( Straight Angle)
But, from above (1) and (2)
∠1 + ∠2 + ∠3 = 180° ( as ∠4 = ∠2, ∠5 = ∠3)
Hence, ∠1 + ∠2 + ∠3 = 180°
Hence Proved.
The MODE is the number or numbers that occur most often in a set.
Answer:
$6.88
Step-by-step explanation:
We are trying to compare two options: Buying a magazine for 12 months or for just 1 year.
To solve this, we can multiply the monthly rate by 12 because there are 12 months in a year.
5.99 x 12 = 71.88
The other option is to just pay $65 dollars for a whole year (12 months).
Comparing the two options, we see paying for the whole year is cheaper than paying for each month individually. Because of this, we can subtract $65, the cheaper option, from $71.88 to get $6.88
Chris will save $6.88 by paying for the whole year instead of purchasing for each month.
If you observe the 4 graphical representations you will see that except stem and leaf plot, the rest 3 represent the same information.
As the time is increasing, the frequency of students who listen to music is decreasing. The frequency is maximum for the first group 0 - 1 and least for the last group 6 - 7.
The ranges shown in both Frequency Table and Histogram are the same.
So, the following options are correct:
<span>B) One of the displays does not show the same information as the others.
C) The first three displays show that as time increases, frequency decreases.</span>
