In a certain industry, about 15 percent of the workers showed some signs of ill effects due to radiation. after management had claimed that improvements had been made, 140 workers were tested and 19 experienced some ill effects due to radiation. does this results support management's claim?

This results do not support management's claim.

Step-by-step explanation:

Before the improvements, about 15 percent of the workers showed some signs of ill effects due to radiation.

Aftter the improvements, 40 workers were tested and 19 experienced some ill effects due to radiation. 19/140 = 0.1357 = 13.57% of workers reported some ill effects from radiation. This is a very small decrease from 15%, so this results do not support management's claim.

x= 149. 24+7=31. 180-31=149

your welcome

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
