Answer:
$3242
Step-by-step explanation:
If each room mates bank account loses $810.50 after paying rent, it means they are spending that on rent. Since there are 4 friends, just do $810.50 times 4 and that's the answer of how much rent costs in total.
Probability helps us to know the chances of an event occurring. The estimated number of left-handed persons in the school is 89.
<h3>What is Probability?</h3>
Probability helps us to know the chances of an event occurring.
Given the number of girls is 320, the probability that a girl is left-handed is 0.2. Therefore, the number of girls who are left-handed is,
Number of left-handed girls = (320×0.2) = 64
Given the number of boys is 250, the probability that a boy is left-handed is 0.1. Therefore, the number of boys who are left-handed is,
Number of left-handed boys= (250×0.1) = 25
Hence, the estimated number of left-handed persons in the school is 89.

Answer:
m<B = 62°
Step-by-step explanation:
Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:
m<B = m<U
m<B = (3y + 2)°
m<U = (4y - 18)°
Thus,
3y + 2 = 4y - 18
Collect like terms
18 + 2 = 4y - 3y
20 = y
y = 20
m<B = (3y + 2)°
Plug in the value of x
m<B = 3(20) + 2
m<B = 60 + 2
m<B = 62°
