10 X 5 = 50
(2x-5) • (2x+5) are the expressions equivalent to 4x^2-25
Hi there!
Answer:
<u><em>x=403 and 403=x</em></u>
Step-by-step explanation:
Because a student says the answer is 347 is not the right answer. The final answer should be x=403 and 403=x.
375=x-28
Switch sides.
x-28=375
add by 28 both sides of an equation.
x-28+28=375+28
simplify.
x=403 and 403=x
403-28=375
28+375=403
Hope this helps!

Answer:
He wont foul out with probability 0.9093
Step-by-step explanation:
The total number of fools he picked is a Binomial ditribution noted by X with parameters p = 0.05 and N = 48. The mean of this random variable is μ = np = 48*0.05 = 2.4 and the variance is σ² = np(1-p) = 2.4*0.95 = 2.28, hence its standard deviation is σ = √2.28 = 1.51.
Note that, if approximate probability is asked, we could just approximate X with a Normal random variable with mean 2.4 and standard deviation 1.51 (this can be done because of the central limit theorem). We will calculate the probability manually. He wont foul out if he picks 0,1,2,3 or 4 fouls, thus

As a consecuence, he wont foul out with probability 0.9093.
You jogged 3.7 total miles! 2.2 - 0/7 = 1.5 + 2.2 = 3.7! Hope I helped!
