Answer:
Heather sent 28, Pablo sent 19, and Shen sent 76.
Step-by-step explanation:
This will be your equation
123 = H (Heather) + P (Pablo) + S (Shen)
This is the extra stuff
P + 9 = H
4P = S
Substitute so there is only P then use that to solve for the rest
123 = P + 9 + P + 4P
Then solve
123 = 6P + 9
123 - 9 = 6P + 9 - 9
114 = 6P
19 = P
Then substitute for the extra equations
19 (P) + 9 = 28 (H)
19 (P) * 4 = 76

Answer:
2.5% chance of finding a defective headset
970
Step-by-step explanation:
3% of the headsets found defective.
If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects,
easy to find percent 273/280=0.975
multiply by 100
97.5 then get 100-97.5=2.5
2.5% chance of finding a defective headset
ok 1,000 units of empirical probability
so the good ones
1,000/100=1
10= 1 percent
10*97=970
970
Sinθ = x

cos θ = square root of (1−x2)
sin^2θ + cos^2θ <span>= 1
</span>cos θ = square root of (1- sin^2θ)
tan(sin−1 x + cos−1 y) = tan(θ + square root of (1- sin^2θ))
tan(sin−1 x + cos−1 y) = <span>tan(θ+α)
