45 minutes * 6 days = 270 minutes at the gum

but we need to change minutes to hours

1 hours = 60 minutes

270 minutes * 1 hr/60 minutes =

270/60 hours

divide top and bottom by 10

27/6

divide top and bottom by 3

9/2

4.5 hours

Answer:

$2n^3-3n^2-7n+3$

Step-by-step explanation:

$(n^2 -3n +1)(2n + 3) =\\n^2(2n) - (3n)(2n) + (1)2n + (n^2)(3) + (-3n)(3) + (1)(3)=\\2n^3 - 6n^2 + 2n + 3n^2 -9n + 3 =\\$

Collecting like terms and simplifying yields

$2n^3-3n^2-7n+3$

Find z such that 6% of the standard normal curve lies to the right of z.

yulyashka [42]

P(Z ≥ z) = 1 - P(Z ≤ z) = 0.06

==> P(Z ≤ z) = 0.94

==> z ≈ 1.7507

So I am doing geometry in my math class, and I can't figure how how to do some of the problems.We have angles and you have to fi

Marianna [84]

Ok, so in the problem there are 5 angles given but you really only need to focus on <KNL and <MNL. these two angles are a linear pair, or supplementary, which means that they add up to 180˚. so, if <KNL is 38˚, then <MNL is 142˚. 180-38=142

hope this helped
