Answer:
Name the rooms in basement, ground floor and the attic.
Step-by-step explanation:
The house has 3 levels: basement, ground floor and the attic.
In the basement there's basement study and a laundry room.
On the ground floor there's a kitchen, a dining room and a living room.
In the attic there is a bathroom and two bedrooms: one for children and the other one for the parents.
Answer:
3 weeks
Step-by-step explanation:
If St. Augustine grass can grow at a rate of 4 over 7 centimeters per week, then for 12 over 7 centimeters it will take :
12 / 7 centimeters ÷ 4 / 7 centimeters
= 3 weeks
Explanation in words :
If the grass can grow at a rate of 4/7 centimeters per week, and it grows 12/7 centimeters but we don't know how many weeks it took, we just have to divide <em>12</em><em>/</em><em>7</em><em> </em><em>from</em><em> </em><em>4</em><em>/</em><em>7</em><em> </em>to get a result of <em>3.</em><em>.</em><em>.</em>
1) Always be polite and professional.
2) Specifically address the points that you disagree with.
3) Provide Evidence.
4) Close with a brief summary of your rebuttal.
(a)
The binomial distribution can be used because the current situation satisfies all of the following:
1. The probability of success (p=85%) is known and remains constant during the whole experiment
2. The number of trials (n=40) is known and constant.
3. Each trial is a bernoulli trial (success or failure only)
4. All trials are (assumed) independent of each other.
The probability of x successes is therefore
P(X=x)=C(n,x)(p^x)(1-p)^(n-x)
(b) P(X=35) means the probability of 35 successes out of 40 trials at p=0.85
and
P(X=35)=C(40,35)*0.85^35*0.15^5=658008*0.003386*0.00007594
=0.16918
(c) P(X>=35)=∑ P(X=i) for i=35 to 40
=0.16918+0.13315+0.08157+0.03649+0.01060+0.00150
=0.4325
(d) P(X<20)=∑ P(X=i) for i=0 to 19
=0.00000003513 (individual probabilities are very small).
Let's say 2y < 18 - 2x
so
4x - 2y > 3
4x - 18 - 2x > 3
2x > 21
2x/2 > 21/2
x > 10.5
2y < 18 - 2(10.5)
2y < 18 - 21
2y < -3
y < 1.5
