Answer:
0.875
Step-by-step explanation:
This is a binomial distribution because a child can be either a boy or a girl. We denote the probability of being a boy as p and being a girl as q. Both are mutually exclusive. The questions both are equally likely. Hence, p = q = 0.5.
The event of having at least a boy is the complement of the event of having no boy. Now the probability of having no boy is the the probability of all children being girls. This is given by
Then, the probability of at least 1 boy, by the law of complements, is
The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
Answer:
The answer is y is 0.05.
Explanation:
At cos(2x) and the left and right boundaries are at 400 pm.
At 0 pm = cos(2π × x ÷ ∧) = 1
So,
A has to be 0.075.
it looks like at 300 pm, y = 0.05.
0.05 = 0.075 × cos(2π × 300 pm ÷ ∧)
= 0.05.
Answer:
3.3
Step-by-step explanation:
7lb 3oz
3oz/16oz=.1875lb
7lb+.1875lb=7.1875lb
7.1875lb/2.2kg=3.27kg
