you need 1661.06 ft squared of carpet to completely cover the floor or a round room. what is the diameter of the room.

Answers

Answer 1

Answer:

46 ft

Step-by-step explanation:

A = π×d²/4

d² = √4×A /π

= √4×1611.06 / 3.14

=√ 2116

= 46 ft

Answer 2

Answer:

46 feet squared

Step-by-step explanation:

A = π×d²/4

d² = √(4×A /π)

= √(4×1611.06 / 3.14)

= 2116

= 46 ft squared

Answers

Answer: The given expression (3x − 5) − (4x + 6) =  -x - 11.

Step-by-step explanation:

Given : Expression (3x − 5) − (4x + 6).

We have to simplify the given expression.

Consider the given expression (3x − 5) − (4x + 6).

Remove Parentheses ,

we have,

(3x − 5) − (4x + 6) = 3x - 5 - 4x -6

Combining like terms, we have,

A fair coin is flipped three times. Let X be the number of heads observed. (a) Give both the possible values and probability mass function of X. (b) Find P(X ≥ 1) and P(X > 1). (c) Compute E[X] and V ar(X).

Answers

Answer:

a)

The possible values are 0, 1, 2 and 3.

The probability mass function of X is:

P(X = 0) = 0.125

P(X = 1) = 0.375

P(X = 2) = 0.375

P(X = 3) = 0.125

b)

[tex]P(X \geq 1) = 0.875[/tex], [tex]P(X > 1) = 0.5[/tex]

c) E(X) = 1.5, Var(X) = 0.75

Step-by-step explanation:

For it time the coin is flipped, there are only two possible outcomes. Either it comes up heads, or it comes up tails. Each toss is independent of other tosses. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The variance of the binomial distribution is:

[tex]V(X) = np(1-p)[/tex]

A fair coin is flipped three times.

This means that [tex]n = 3[/tex]

Fair coin means that it is equally as likely to be heads or tails, so [tex]p = \frac{1}{2} = 0.5[/tex]

a) Give both the possible values and probability mass function of X.

The possible values are from 0 to n, so 0, 1, 2 and 3.

The probability mass function is the probability of each outcome. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125[/tex]

[tex]P(X = 1) = C_{3,1}.(0.5)^{1}.(0.5)^{2} = 0.375[/tex]

[tex]P(X = 2) = C_{3,2}.(0.5)^{2}.(0.5)^{1} = 0.375[/tex]

[tex]P(X = 3) = C_{3,0}.(0.5)^{3}.(0.5)^{0} = 0.125[/tex]

(b) Find P(X ≥ 1) and P(X > 1).

[tex]P(X \geq 1) = P(X = 1) + P(X = 2) + P(X = 3) = 0.375 + 0.375 + 0.125 = 0.875[/tex]

[tex]P(X > 1) = P(X = 2) + P(X = 3) = 0.375 + 0.125 = 0.5[/tex]

(c) Compute E[X] and Var(X).

[tex]E(X) = np = 3*0.5 = 1.5[/tex]

[tex]Var(X) = np(1-p) = 3*0.5*0.5 = 0.75[/tex]

3x + 1/3y=12
2y=18x+72

Show all work

A no solution
B one solution
C infinity solutions

Answers

Answer:

B one solution

Step-by-step explanation:

3x + 1/3y=12

2y=18x+72; y = 18x/2 +72/2; y =9x+36

3x + 1/3y=12

multiply all through by 3

9x + y = 36

9x + 9x+36 = 36

18x =36-36= 0

x= 0/18 = 0

y =9x+36

y = 9(0) +36 = 0+36= 36

12. What is P(x> 242)?
O A. 0.16
B. 0.475
C. 0.84
D. 0.975

Answers

0.975 is P(x ≥242) with a mean of 266 and standard deviation of 12

The required value of P(x> 242) = is 0.975 for normal distribution. Option D is correct.

The normal distribution has a mean of 266 and a standard deviation of

12. What is P(x> 242) is to determine.

Whata  is normal distribution?

Normal distributions can be altered to standard normal distributions by the formula:

Z = (X - μ)/σ

Where x is a value from the initial normal distribution, μ is the mean of the initial normal distribution, and σ is the standard deviation of the initial normal distribution. The standard normal distribution is periodically called the z distribution.

Now,
z = X - 266 /12
p(x > 242) = P [(X - 266)/12 ≥ (242 - 266)/12]
p(x > 242) = P [z ≥ -24/12]
p(x > 242) = P [z ≥ -2]
p(x > 242) = P [z ≤ 2]
p(x > 242) = 0.975  (from Z table).


Thus, the required value of P(x> 242) = is 0.975. Option D is correct.
