Answer:

have you tried 2.04?

Step-by-step explanation:

5(9) + 2(6) / 3 + 5^{2}

45 + 12 / 3 + 25

57 / 28

≈ 2.04

you could also try this if that doesn't work:

5(9) + 2(6) / 3 + 5^{2}

45 + 12 / 3 + 25

45 + 4 + 25

74

hope this helps :)

What do they represent?
andrey2020 [161]

Answer:

A

Step-by-step explanation:

If you convert the first equation to y=mx+b form, it will be the same as the second equation.

6x - 15y = 15

-15y = -6x + 15

y = \frac{2}{5}x -1

Because the 2 equations are the same now, they are the same line.

TanA+tanB+tanAtanB=1 If A+B=45 degree​
djyliett [7]

Answer:

See below

Step-by-step explanation:

\tan A+\tan B + \tan A.\tan B = 1\\\\ \implies \: \tan A +  \tan B =  1 -  \tan A.\tan B  \\  \\ \implies \:  \frac{\tan A +  \tan B}{ 1 -  \tan A.\tan B } = 1\\  \\ \implies \:  \tan (A +  B) = 1 \\  \\ \implies \:  \tan (A +  B) =\tan 45 \degree \\  \\ \implies \:  A +  B = 45 \degree \\  \\  thus \: proved

Consider two events such that P(A) = 1/4 , P(B) = 2/3 , and P(A ∩ B) = 1/5 . Are events A and B independent events?
fredd [130]
P(A) = 1/4
p(B) = 2/3
p(A ∩ B) = 1/5
p(A).p(B) = 2/12 = 1/6 ≠p(A ∩ B )
thus no, they are dependent because P(A) ⋅ P(B) ≠ P(A ∩ B)
