your friend's score=x

twice your friend's score=2*x

then your score=6+2*x

Given that your score is=212

In other words, 6+2*x=212

2*x=212-6

2*x=206

x=206/3

x=103

I need help only on number 3

DochEvi [55]

Gaps have no data in them. So the range 1-2 is a gap.

Clusters are groups of data that are right next to each other.

So the range 3-6 on your dot plot is a cluster, because there is a group of data there with no gaps.

Peaks are the greatest amount of data in the dot plot. 0 and 5 are the peaks because they both have the most data, 4.

Given DEF : RST, find the scale factor.<br><br> PLEASE HELP!

Elena L [17]

Answer:

scale factor 3 : 4
x = 12

Step-by-step explanation:

To find the scale factor from ΔDEF to ΔRST, find a measure on ΔDEF and a corresponding measure on ΔRST, then write them in the form required for the scale factor.

Here, there are numbers on DE, RS, and ST. We see by the similarity statement ΔDEF ~ ΔRST that DE corresponds to RS, so the scale factor is ...

ΔDEF : ΔRST = DE : RS = 3 : 4 . . . scale factor

Using that scale factor, you can write a proportion to find the value of x.

3 : 4 = x : 16 ⇒ 3/4 = x/16

Multiplying the fraction equation by 16, we have ...

x = 16(3/4)

x = 12
