That the black lives matter. if a police officer kills a white man bc the white man is a threat then no one cares but if a police man kills a black man bc a black man is a threat everyone protests. I thought we were = but then black people are out there saying there lives matter. They do but white lives matter too so do blue lives and green lives and purple lives. Everyone matters but if you say that apparently you get in trouble. All lives matter but instead people had to make a program titled black lives matter.

Women's shoe size follow a normal distribution with a mean of size 7.5 and a standard deviation of 1.5 sizes. Using the 68-95-99
Alexus [3.1K]
Given:
μ = 7.5, the population mean
σ = 1.5, the population standard deviation

According to the 68 - 95 - 99.7 rule, 68% of the population data lies within one standard deviation of the population mean.
Therefore the range of sizes that fit 68% of women is
(7.5-1.5, 7.5+1.5) = (6.0, 9.0)

Answer: 6.0 to 9.0

5. Write an equation for at least one line perpendicular to the line with eachequation.c. 19x
tiny-mole [99]
The first thing you always do with equations like these is get the y alone by moving everything to the other side. Once this is done, you take the opposite reciprocal of the slope. For example, number a, when you have y alone, is y=-1x+2. So the opposite reciprocal of the slope would be just 1, so the resulting equations would be y=1x+2.
