Solve -3(-8b+7)=3(2b-1)

nekit [7.7K]

Answer: $b=1$

Step-by-step explanation:

Given the equation $-3(-8b+7)=3(2b-1)$ you need to solve for the variable "b".

You need to apply Distributive property on both sides of the equation:

$-3(-8b+7)=3(2b-1)\\\\24b-21=6b-3$

Now you need to add 21 to both sides of the equation:

$24b-21+21=6b-3+21\\\\24b=6b+18$

Subtract $6b$ from both sides:

$24b-6b=6b+18-6b\\\\18b=18$

And finally, you can divide both sides of the equation by 18:

$\frac{18b}{18}=\frac{18}{18}\\\\b=1$

The tallest living man at one time had a height of 262 cm. The shortest living man at that time had a height of 68.6 cm. Heights

AysviL [449]

Answer:

more the z-score more will be the extreme. therefore tallest man has high extreme

Step-by-step explanation:

Formula for z-score: $\frac{X-\mu }{\sigma}$

where

X is height of tallest man

μ mean height

σ is standard deviation

z score for tallest is

z-score = $\frac{ 262 - 175.32}{8.17} = 10.60$

similarly for shortest man

z-score = $\frac{68.6 - 175.32}{8.17} = - 13.06$

more the z-score more will be the extreme. therefore tallest man has high extreme
