How do you solve this?
masha68 [24]
Here's what i found online:

<span>a/3+4=6

We simplify the equation to the form, which is simple to understand
<span>a/3+4=6

Simplifying:
<span> + 0.333333333333a+4=6

We move all terms containing a to the left and all other terms to the right.
<span> + 0.333333333333a=+6-4

We simplify left and right side of the equation.
<span> + 0.333333333333a=+2

We divide both sides of the equation by 0.333333333333 to get a.
<span>a=6

Hope this helped :-)</span></span></span></span></span></span>

The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds.Refer to
Dafna11 [192]

Given that

the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.

And we need to find What is the minimum weight of the middle 95% of the players?

Explanation -

Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.

Two standard deviations = 2 x 25 pounds = 50 pounds

So the minimum weight = 200 pounds - 50 pounds = 150 pounds

Hence the final answer is 150 pounds.
