Answer:
cos Θ
Step-by-step explanation:
I assume you mean
sec Θ − tan Θ sin Θ =
= 1 / cos Θ - sin Θ / cos Θ × sin Θ
= 1 / cos Θ - sin² Θ / cos Θ
= (1 - sin² Θ) / cos Θ Eq. 1
Recall the identity: sin² Θ + cos² Θ = 1
Subtract sin² Θ from both sides:
cos² Θ = 1 - sin² Θ
Substitute 1 - sin² Θ with cos² Θ in Eq. 1
= cos² Θ / cos Θ
= cos Θ
So first you would multiply $6.50 by 4.5 and you get 29.25, so that represents how much she would make in one day! Then multiply 5 days a week by 6 weeks and you get 30 then multiply $29.25 by 30 to get the total!
Balance - purchase
$200 - $350.25
= -$150.25
Your account would have -$150.25
ANSWER:
The probability is 0.25
STEP-BY-STEP EXPLANATION:
In this case, we must take into account the number of children who have brown eyes and black hair.
If we look at the table we can see that it is 0.25, that is, if there are 100 children, 25 have these characteristics, therefore
