Mathematics
1 answer:
Mariana [72]3 years ago

Answer:

12

Step-by-step explanation:

We know that AD=BC and that AB=CD. We also know the perimeter of the rectangle ABCD to be 54 units.

From this, we can add up the sides which will be equal to 54 units.

AD+BC+AB+CD=54

2x+2x+3x-3+3x-3=54

10x=60

x=6

Since we are trying to find the length of side BC we substitute this value back into 2x.

BC=2x =2*6=12

Therefore, the length of BC is 12 units.

In a certain country, the true probability of a baby being a boy is 0.519. Among the next nine randomly selected births
yawa3891 [41]

Answer:

0.9973

Step-by-step explanation:

Given :

Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481

1 - p = 0.481

n = 9

Probability that atleast one is girl

Usingbthe binomial probability distribution :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

USing the binomial probability calculator :

p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)

p(x ≥ 1) = 0.9973 ( from calculator).

Upper Quartile,  = 40 (The middle value between 38 and 42)

Highest value = 42


Five summaries of Town B

Lowest value = 0

Lower Quartile,  = 4 (The middle value between 0 and 8)

Median,  = 9

Upper Quartile,  = 20 (The middle value between 19 and 21)
