Answer:

Percentage increase= 37.5%

Step-by-step explanation:

Giving the following information:

Sales on weekdays (Q0)= 240 units

Sales on weekends (Q1)= 330 units

To calculate the percentage increase, we need to use the following formula:

Percentage increase= [(Q1/Q0) - 1]*100

Percentage increase= [(330/240) - 1]*100

Percentage increase= 37.5%

Answer:

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:

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

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)

Answer: x=−1.226024

Step-by-step explanation: Let's solve your equation step-by-step.

8x+2=5

Solve Exponent.

8x+2=5

log(8x+2)=log(5)(Take log of both sides)

(x+2)*(log(8))=log(5)

x+2=

log(5)

log(8)

x+2=0.773976

x+2−2=0.773976−2(Subtract 2 from both sides)

x=−1.226024

Answer:

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.

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

[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]

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.

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%.

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: No because BC is not perpendicular to AB.

Step-by-step explanation:

Yes, rhombus ABCD is a square as all four angles of the rhombus are right angles.

A square is a special type of rhombus where all four sides have the same length and all four angles are right angles.

In this case, we can see that all four sides of the rhombus have the same length by calculating the distance between each pair of vertices. For example, the distance between A and B is:

distance = [tex]\sqrt{[/tex] [tex]((-8 - (-1))^2[/tex] + [tex](11 - (-13))^2[/tex])

distance = [tex]\sqrt{[/tex] ([tex]7^2[/tex] + [tex]24^2[/tex])

distance = [tex]\sqrt{[/tex] (625) = 25

The distance between each other pair of vertices is also 25, so all four sides of the rhombus have the same length.

We can also see that all four angles of the rhombus are right angles by calculating the angles between each pair of adjacent sides. For example, the angle between sides AB and BC is:

angle = arctan((13 - (-13))/(-8 - (-1)))

angle = arctan(26/7)

angle = 78.6°

The angle between each other pair of adjacent sides is also 78.6°, so all four angles of the rhombus are right angles.

Therefore, rhombus ABCD is a square.

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:

[tex]T_{10} = 0.05078125[/tex]

[tex]S_{18} = 51.9998016358[/tex]

Step-by-step explanation:

Given:

Sequence = 26, 13, 6.5 ....

Solving (a): The 10th term

The sequence is a geometric progression and the nth term will be solved using:

[tex]T_n = ar^{n-1}[/tex]

In this case:

[tex]n = 10[/tex]

[tex]r = \frac{T_2}{T_1}[/tex] --- Common Ratio

[tex]r = \frac{13}{26}[/tex]

[tex]r = 0.5[/tex]

[tex]a = 26[/tex] --- First term

So, [tex]T_n = ar^{n-1}[/tex] becomes

[tex]T_{10} = 26 * 0.5^{10-1}[/tex]

[tex]T_{10} = 26 * 0.5^{9}[/tex]

[tex]T_{10} = 26 * 0.001953125[/tex]

[tex]T_{10} = 0.05078125[/tex]

Solving (b): The sum of first 18 terms

This will be calculated using:

[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]

Substitute values for n, a and r

[tex]S_{18} = \frac{26 * (1 - 0.5^{18})}{1 - 0.5}[/tex]

[tex]S_{18} = \frac{25.9999008179}{0.5}[/tex]

[tex]S_{18} = 51.9998016358[/tex]

Hence, the sum of first 18 terms is 51.9998016358
