(ASAP 100 POINTS AND BRAINLIEST) The two dot plots below compare the forearm lengths of two groups of schoolchildren:

Two dot plots are shown one below the other. The title for the top dot plot is Forearm Length, Group A and the title for the bottom plot is Forearm Length, Group B. Below the line for each dot plot is written Length followed by inches in parentheses. There are markings from 11 to 14 on each line at intervals of one. For the top line there are 3 dots above the second mark, 4 dots above the third mark, and 3 dots above the fourth mark. For the bottom line there are 3 dots above the first mark, 5 dots above the second mark, and 2 dots above the third mark.

Based on visual inspection of the dot plots, which group appears to have the longer average forearm length?

Group B, because three children in the group have the least forearm length of 11 inches
Group A, because three children in the group have the least forearm length of 11 inches
Group A, because seven children have a forearm length longer than 12 inches
Group B, because two children have a forearm length longer than 12 inches

Answer:Me!" (stylized in all caps) is a song recorded by American singer-songwriter Taylor Swift featuring American singer Brendon Urie of Panic! at the Disco. It was released on April 26, 2019, through Republic Records, as Swift's first single after signing with the label. The song was revealed and released at the end of a thirteen-day countdown, as the lead single from her seventh studio album, Lover (2019). It was written by Swift, Joel Little and Urie, and produced by Swift and Little. The song was recorded at Electric Lady Studios, New York City and Golden Age West in Auckland, New Zealand in 2018. "Me!" is a cheery, campy bubblegum pop and synth-pop duet, driven by a marching band drumline. It is about embracing one's individuality, with lyrics on self-affirmation and self-love.

"Me!" debuted at number 100 on the US Billboard Hot 100, before surging up to number two the next week, breaking the record for the biggest single-week jump in the chart's history. The song reached the top five in several other countries. It broke several Amazon Music records, including the most first-day streams, most first-week streams and most on-demand voice requests with Alexa of a single debut on the platform. Upon release, the song received mixed reviews from music critics, who were favorable towards the bubbly production and the duo's vocal chemistry, but divided over the lyrics—some complimented the tongue-in-cheek songwriting, while others called it weak. "Me!" has since been certified double-platinum by Recording Industry As

Step-by-step explanation:

Answer:

D. Group A, because four children in the group have the least forearm length of 10 inches.

Step-by-step explanation:

It can be seen that more children in group B have forearm length more than 12 inches and there are no children who have forearm length greater than 12 inches in group A.

So, based on the visual inspection of the dot plots, group A, appears to have longer average forearm length.

In order to verify the claim let us find the mean

Mean of Group A

Mean of Group B

So, group A has shorter average forearm length.

what is the measure of angle y

Answers

Answer:

Step-by-step explanation:

You are given a right triangle. The square in the  corner of the triangle tells you that that angle = 90°.  Also the sum of all three angles in a triangle = 180°.

Sum of the angles in the triangle = 40° + 90° + y = 180°

                                                              130° + y = 180°

                                                                       y = 180° - 130°  

                                                                       y = 50°

Second way:

The acute angles of a right triangle = 90°. Therefore  40° + y =  90°

                                                                                                 y = 90° - 40°

                                                                                                 y = 50°
