Answer:

a

[tex]P(X = 4 ) = 0.0677 [/tex]

b

[tex]P(X \ge 1  ) =   0.9424 [/tex]

Step-by-step explanation:

From the question we are told that

   The probability of a US household having an internet access in 2001 is  p = 0.51

   The sample size is  n = 4

Generally the distribution of the number of US household with internet access at 2001  follows a binomial distribution  

i.e  

         [tex]X  \~ \ \ \  B(n , p)[/tex]

and the probability distribution function for binomial  distribution is  

      [tex]P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

   Generally  the probability that all four had Internet access in 2001 is mathematically represented as

      [tex]P(X = 4 ) =  ^{4}C_4 *  (0.51)^4  (1- 0.51)^{4-4}[/tex]

=>  [tex]P(X = 4 ) = 0.0677 [/tex]

Generally  the probability that at least one of four randomly selected U.S. households had Internet access in 2001 is mathematically represented as

      [tex]P(X \ge 1  ) =  1 - P(X <  1 ) =  1-  P(X = 0 )[/tex]

=>   [tex]P(X \ge 1  ) =   1-  [^{4}C_0 *  (0.51 )^0 *  (1- 0.51 )^{4-0 } ][/tex]

=>   [tex]P(X \ge 1  ) =   1-  [1 *  1 *  (0.49 )^{4 } ][/tex]

=>   [tex]P(X \ge 1  ) =   0.9424 [/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = x^2 - x - 72

y = (x - 9)(x + 8)

53)

The altitude of a triangle is always perpendicular to the base, therefore:

5x° must equal 90°.

Solve for x:

5x = 90

5x / 5 = 90 / 5   ----> x = 18

KL is equal to  2x - 5, so plug the value of x into the equation:

KL = 2(18) - 5

KL = 36 - 5   ---> KL = 31

54)

A median bisects the base, therefore:

AD ≅ DC

Set both equations equal to each other:

3x = 2x + 1

Subtract 2x from both sides:

x = 1

Plug in the value of x into the equation for DC:

2(1) + 1 = 3.

DC = 3.

Answer:

x < 16

Step-by-step explanation:

4x < 64

To solve for x, we simply divide by 4 on both sides. This results us with:

x < 16

4x <64

Divide both sides by 4:

x < 16

The rate of flow of water through a pipe is gallons per day is 3.333%.

Given that, water flows through a pipe at a rate of 4 quarts per month.

We need to express this rate of flow in gallons per day.

4 quarts will make a gallon.

Now, according to the question, 1 gallon of water flows through a pipe per month.

We know that number of days in a month is equal to 30 days.

Per day=1 gallon of water/Number of days in a month

=1/30 gallons of water.

The rate of flow in gallons per day=1/30 × 100

=3.3333%≈3.333%

Therefore, the rate of flow of water through a pipe is gallons per day is 3.333%.

Step-by-step explanation:

The fraction 25/6 is approximately equal to 4.17 as a decimal.

We have,

To find the decimal equivalent of 25/6, we perform the division operation:

25 ÷ 6 = 4.166666...

The division result is a recurring decimal, which means it continues indefinitely without repeating.

However, to represent it in decimal form, we can round it to a certain number of decimal places.

Rounding to two decimal places,

The decimal equivalent of 25/6 is approximately 4.17.

Therefore,

Answer:

A) False

B) False

Step-by-step explanation:

A. Two angles whose measures add up to 90° are said to be complementary, while two angles are adjacent when formed beside each other. So, adjacent angles might be complementary or supplementary. Thus, the answer to the first part of the question is false.

B. When two angles share a side, they are said to be adjacent to each other. But supplementary angles add up to [tex]180^{o}[/tex]. Since adjacent angles might be complementary or supplementary, then the answer to the second part of the question is false.

Answer:  0.92 feet (choice B)

You're close but not quite there. To get the answer, you divide 29.44 over 32

If you had 32 feet of banner and 32 students, then each student would get 32/32 = 1 foot. Since the length of the banner is smaller than the number of students, this means each student only gets a fraction of a foot. This fraction value is fairly close to 1 because 29.44 is close to 32.

Answer:

The number of pizzas sold during A- lunch is 64

Step-by-step explanation:

Let us solve the question using the ratio method

∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3

∵ There were 48 nachos sold

→ By using the ratio method

→ Pizza  :  Nachos

→  4        :   3

→  x        :  48

→ use the cross multiplication

∵ x × 3 = 4 × 48

∴ 3x = 192

→ Divide both sides by 3

∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{192}{3}[/tex]

∴ x = 64

∴ The number of pizzas sold during A- lunch is 64

relation

Step-by-step explanation:

First of all, all functions are relations, but not all relations are functions.

A function is a relation where one element in the domain is paired exactly with one element of the range.

A relation assigns one element of the domain to one or more elements of the range.

The range is any set of ordered pairs, while the function is a set where the group of pairs do not share the same first coordinate.

Step-by-step explanation:

first we distribute the a to the 2x and -3

2ax -3a=bx+5

we move the -3a over by adding 3a

2ax=bx+5+3a

then we move the bx over

2ax-bx=5+3a

we can now group the left side like this

x(2a-b)=5+3a)

to find x all we must do is divide both sides by (2a-b)

x=(3a+5)/(2a-b)

Two vertical asymptotes exist. The leftmost one's equation is, x = -6, and the rightmost one's equation is, x = 6.

Domain: ,(-∞, -6) U (-6, 6) U (6, ∞)

There are two vertical asymptotes on the f(x) graph. The leftmost one's equation is:

x = -6

and the equation of the rightmost one is:

x = 6

Part B

The vertical asymptotes at x=-6 and x=6 define the domain of f as follows:

(-∞, -6) U (-6, 6) U (6, ∞)

Therefore, Two vertical asymptotes exist. The leftmost one's equation is x = -6, whereas the rightmost one's equation is x = 6.
