Answer:

The cost of one unit of electricity is $0.185

Step-by-step explanation:

Amount charged = $120.99

Units of electricity used = 654

The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.

So that,

cost of one unit of electricity = [tex]\frac{120.99}{654}[/tex]

                                    = 0.185

cost of one unit of electricity = $0.185

This implies that the cost of electricity used is charged at $0.185 per unit.

Thus for 654 units of electricity used, the cost would be;

654 x $0.185 = $120.99

Answer:

54

Step-by-step explanation:

In a stem and leaf plot, the stems are typically increments of ten. Therefore, 5, or 50, is the largest stem. Now, in that row, we have to find the biggest leaf. Luckily for us, in stem and leaf plots, the leaves are organized in a least-to-greatest order. We go down to the end of the row and boom! 4. Put the stem and leaf together and we have 54.

Answer:

$21.73

Step-by-step explanation:

6% = 0.06

$20.50x0.06 = $1.23

$20.50 + $1.23 = $21.73

The graph is discrete and the coach can buy 9 basketballs with $117.

Continuous functions are those functions for which the value of function can take any number on a certain interval.

Discrete functions, on the other hand, takes separate and distinct values for the function.

The function here is,

a = 13 b

where a is the amount spending on the store and b is the number of basketball she buys.

(a) The table is shown below:

b : 0      1        2       3       4  

a : 0      13     26     39     52

The graph is discrete because the function values are discrete.

(b) If the coach spent $117,

a = 117

b = a / 13

b = 117 / 13

b = 9

Hence the graph of the function is discrete and the coach can buy 9 basketballs with the given amount.

Answer:a

Step-by-step explanation:

The function h(x) is increasing on the interval (5, ∞).

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

The function h(x) = |x − 5| + 2 is increasing on an interval where the derivative is positive.

If x < 5, then h(x) = -(x-5) + 2 = 7-x, and if x > 5, then h(x) = x - 5 + 2 = x - 3. Thus,

h'(x) =[tex]\left \{ {{ -1, for x < 5} \atop { 1, for x > 5}} \right.[/tex]

Since h'(x) is positive for all x > 5, the function h(x) is increasing on the interval (5, ∞).

Complete question:

On what interval is the function h(x) = |x − 5| + 2 increasing?

Answer:

Let's define:

C = number of children tickets bought

A = number of adult tickets bought.

We know that "On a certain day,  if 14 times as many children's tickets were bought as adult meal tickets"

Then we have:

C = 14*A

And we also know that:

"the total revenue  from selling all tickets was $2,584"

Then:

C*$4 + A*$9 = $2,584

Then we have a system of equations:

C = 14*A

C*$4 + A*$9 = $2,584

The first step to solve these is to isolate one of the variables in one of the equations, and then replacing it in the other equation. We can already see that C is already isolated in the first equation, then we can just replace it in the second one to get:

(14*A)*$4 + A*$9 = $2,584

A*$56 + A*$9 = $2,584

A*$65 = $2,584

A = $2,584/$65 = 39.75

Here we should have a whole number, (So one of the numbers given may be incorrect) This is because we can not have a 0.75 of a ticket sold.

In this case, we know that:

C = A*14

C = 39.75*14 = 546.5

We could round this up to get a whole number; 547

About 547 children tickets were sold.

Answer:

x = 120/29

Step-by-step explanation:

-1/6(x + 18) + 1/5(x + 5) = x - 6

-1/6x - 3 + 1/5x + 1 = x - 6

-1/6x + 1/5x + 1 - 3 = x - 6

-1/6x + 1/5x - 2 = x - 6

-5/30 + 6/30x = x - 6 + 2

1/30x = x - 4

1/30x - x = -4

-29/30x = -4

-29/30x • 30/29 = -4 • 30/29

-x = -4/1 • 30/29

-x = -120/29

-x/-1 = 120/29/-1

x = 120/29

Answer:

Selling price of each cap = £6.75 (Approx.)

Step-by-step explanation:

Given:

Number of caps = 500

Cost of caps = Rs. 200,000

Export tax = 5%

Profit = 150%

£ 1 = Rs. 155.63

Find:

Selling price of each cap

Computation:

Cost of 1 cap = 200,000 / 500

Cost of 1 cap = Rs 400

After Add export tax = 400 + 400(5%)

After Add export tax = Rs 420

After profit = 420 + 420(150%)

After profit = Rs 1050

Selling price of each cap = 1,050 / 155.63

Selling price of each cap = £6.75 (Approx.)

Answer:

41 + (D x 1) = L

Step-by-step explanation:

To determine the necessary equation to lengthen a road whose initial measure is 41 miles, knowing that a new mile is built every day, the following equation must be performed:

41 + (D x 1) = L

Thus, if 14 days had passed, the length of the journey would be determined as follows:

41 + (14 x 1) = L

41 + 14 = L

55 = L

Therefore, after 14 days, the road's length will be 55 miles.

Perimeter = 5x - 2

Step-by-step explanation:

Perimeter of the figure = sum of all its side lengths

Thus:

Perimeter = (x - 4) + (x + 3) + (x - 2) + x + (x + 1)

Perimeter = x - 4 + x + 3 + x - 2 + x + x + 1

Collect like terms

Perimeter = x + x + x + x + x - 4 + 3 - 2 + 1

Perimeter = 5x - 2

We reject H₀, we have enough evidence to support the claim that the porcentage of residents who favor construction is over 35%

Step-by-step explanation:

Sample size    n  = 1300

Sample  proportion   p = 38 %      =  0,38   then  q = 62%   q =  0,62

The size of the sample is enough to consider the binomial distribution can approximate to normal distribution

p*n  =  1300*0,38     q*n  =  1300*0,62  

p*n > 10    q*n> 10

Population proportion   35%        p₀  = 35 %    p₀  = 0,35

Hypothesis Test :

Null Hypothesis                                         H₀           p = p₀

Alternative Hypothesis                             Ha           p  > p₀

The hypothesis test is a one-tail test to the right

Significance Level   α  =  0,05  we go to z-table and find z(c)

z(c) =  1,64

To calculate  z(s)

z(s)  =  (  p  -  p₀ ) / √ p*q/ n

z(s)  =  0,38  -  0,35  / √ ( 0,38 * 0,62) / 1300

z(s)  =  0,03 / 0,013

z(s)  =  2,307

Comparing  z(c)  and  z(s)

z(s)  >  z(c)      2,307  >  1,64

z(s)  is in the rejection region for H₀, we must reject H₀

We have enough evidence to support the claim
