If Joan uses no electricity, her total cost for the month is $12.D. Joan pays $12 for every kilowatt-hour of electricity that she uses.E. The initial value represents the maximum cost per month for electricity.F. A graph of the total cost for x ≥ 0 kilowatt-hours of energy used is a straight line.G. The slope of the function C(x) represents the increase in cost for each kilowatt hour used.

Remember that we can get the mean of a dataset by adding up each datum and dividing such sum by the number of data.

Now, let's call the number of puppets Marco made M

This way, we would have that:

Solving for M :

Therefore, we can conclude that Marco made 4 puppets.

Let x be a random variable representing the blood pressures of adults in the USA. Since it is normally distributed, we would apply the formula for determining z score which is expressed as

z = (mean - population mean)/standard deviation

From the information given,

population mean = 121

Standard deviation = 16

For stage 2 high blood pressure, the probability is

P(x greater than or equal to 160). It is also equal to 1 - P(x < 160)

Thus, for x = 160, we have

z = (160 - 121)/16 = 2.4375

From the standard normal distribution table, the probability value corresponding to a z score of 2.4375 is 0.9927

P(x < 160) = 0.9927

P(x greater than or equal to 160) = 1 - 0.9927 = 0.0073

Converting to percentage, it is 0.0073 * 100 = 0.73%

b) If 2000 peaople were sampled, the number of people with stage 2 high blood pressure would be

0.73/100 * 2000 14.6

To the nearest person, it is 15 people

c) For stage 1, the probability is

P(140 < x < 160)

For x = 140,

z = (140 - 121)/16 = 1.1875

From the standard normal distribution table, the probability value corresponding to a z score of 1.1875 is 0.883

Recall, for x = 160, the probaility is 0.9927

Thus,

P(140 < x < 160) = 0.9927 - 0.883 = 0.1097

Converting to percentage, it is

0.1097 * 100 = 10.97%

d) The 30th percentile refers to all values of blood pressure below k, where k is the 30th percentile. This means that we would find

P(x < k) = 0.3

The z score corresponding to a probability value of 0.3 is - 0.52

Thus,

(k - 121)/16 = - 0.52

k - 121 = - 0.52 * 16 = - 8.32

k = - 8.32 + 121

k = 112.68

The pressure for the 30th percentile is 112.68

The given information is the shape is a rectangle.

About the diagonals of rectangles, there are two known properties:

- The diagonals of a rectangle bisect each other

- Both diagonals have the same length

Then, the answer is option C. They have the same length

The side AB = BD

7x + 10 = 9x - 2

SImplify for x :

Subtract 7x from both side :

7x + 10 - 7x = 9x - 7x - 2

10 = 2x - 2

Add 2 on both side :

10 + 2 = 2x - 2 + 2

12 = 2x

divide both side by 2 :

2x/2 = 12/2

x = 6

You have the following fraction:

180000/120000

First of all you cancel zeros:

180000/120000 = 18/12

next, you can simplify

18/12 = 9/6 = 3/2

finally 3/2 is:

3/2 = 1.5

Hence: 180000/120000 = 1.5

Furthermore, for the following fraction:

0.11/0.08

Here, you can use a calculator. The result is:

0.11/0.08 = 1.375

that is approximately

1.375 ≈ 1.4

For other fractions:

350/10,000 = 35/1,000 = 0.035

which is approximately

0.035 ≈ 0.04

6.01/7.2 = 0.834 ≈ 0.83

Given a parallelogram as shown below:

The formula to calculate the area of the parallelogram is given to be:

From the question provided, we have the following parameters:

Therefore, we can use the formula to calculate the area as shown below:

The area of the parallelogram is 99 squared yards (99 yd²).

First, we are going to divide the figure and named new points X and Y as:

Now, we know that TS is the sum of TX and XS.

TS = TX + XS

Adittionally, TX has the same length of HJ, so:

TX = HJ = 14

Now, we want to know the length of YK, and we can calculate it using the following equation:

LK = LY + YK LY is also equal to HJ, so LY = 14

42 = 14 + YK

42 - 14 = YK

28 = YK

Finally, since T and S are midpoints, the length of XS is the half of the length of YK. It means that XS is:

XS = YK/2

XS = 28/2

XS = 14

Therefore, TS is equal to:

TS = TX + XS

TS = 14 + 14

TS = 28

Answer: TS = 28

To solve this problem we need to find the fraction of a fraction, for that we just have to multiply them. This is done below:

The section is 16/35 of a mile long.

In a rhombus the length sides are congruent

so

If mmIn the right triangle IFJ

mtan(30)=FJ/IJ

Remember that

FJ=4

substitute the given values

Find the length side IF

Applying Pythagorean Theorem

IF^2=4^2+IJ^2

IJ^2=48

IF^2=16+48

IF^2=64

IF=8 units

that means

side GH=8 units

side JG=side IJ=4√3 units

side FH=2*side FJ=2*4=8 units

The volume of the pyramid is 144 cm³

The volume of a prism is given by the formula:

V = BH

where B is the base area

and H is the height

The base of the the pyramid is the lateral triangle, and the area is given by the formula:

B = 0.5 x b x h

b = 8 cm

h = 6 cm

B = 0.5 x 8 x 6

B = 24 cm²

The volume is then:

V = BH, where H = 6 cm

V = 24 x 6

V = 144 cm³

Given the conditions in the question:

1. sin θ > 0, therefore, it must be positive. From that, we can conclude that y must be on the positive side, therefore, located at the top of the coordinate plane.

2. sec θ < 0, therefore, it must be negative. From that, we can conclude that x must be on the negative side, therefore, located at the left side of the coordinate plane.

Therefore, the quadrant that the θ belongs to is in the top and left of the coordinate plane and that is Quadrant II.

Step-by-step explanation:

I got it right on the test

As observed from the graph, the curve is a straight line from point (-2,-1) to (-5,2).

Consider that the equation of a straight line passing through two points is given by,

So the equation of the line passing through (-2,-1) and (-5,2) is given by,

Note that this function is only for the interval [-2, -5].

Now, the value of 'y' corresponding to the input x=-4 is calculated as,

Given

3 different waters: tap, bottled in glass, and bottled in plastic.

Find

probability that Adina's friend correctly identifies each of the 3 cups of water

Explanation

As we have given three different waters : tap , bottled in glass and bottled in plastic.

number of ways in which the person can make guesses about the 3 cups of water =

number of ways in which person identifies correctly the 3 cups of water = 1

so , probability that Adina's friend correctly identifies each of the 3 cups of water =

so , P = 1/6

Final Answer

Therefore , the probability that adina's friend correctly identifies each of the cup of water = 1/6

To solve this, we will need to convert all values to decimal.

First convert 1/4 to decimal:

Now convert 43% to decimal:

Simplify 5/9:

0.15 is already a decimal value.

Simplify 1/12:

1.4 is already a decimal.

After simplifying, we have the following values:

0.25

0.43

0.56

0.15

0.083

1.4

We can see the values greater than 0.25 are:

0

In a linear relationship, each step of x modifies the y value in the same way.

In the first table, when x = 1, y = 3 and when x = 2, y = 6. This is an increment of 3. If this is a linear relationship, we expect the next value of y to be the previous value plus 3, thus y = 9. But in the table shows x =3 and y = 12. We can rule out the first table.

With similar reasoning, in the second table, we see (1, 2) and (2, 5). This is an increase of the y value of 3. We expect the next value to be y = 8, but we see (3, 9). The second table is not a linear relationship.

In the third table, we see (1, -3) and (2, -5). This is a decrease of -2. We expect the next value of y to be y = -7, and we do see (3, -7). The next value should be y = -9, and the table shows (4, -9). Table 3 shows a linear relationship.

To be sure, let's see the 4th table. We see (1, -2) and (2, -4). This is a decrease of -2. The expected next value is y = -6, but the next point is (3, -2). Fourth table is not a linear relationship.

Thus, the correct answer is the top-right table.

The required Dimensions are 6'' x 8'' x 30'' , That is option A

Distributive property

In this property, multiplying the sum of two or more terms in that add up in a bracket by a number outside the bracket will be equal to multiplying each term in the bracket individually and then followed by sum of the product. In this question:
