Answer:

In the figure attached, the graph of the function is shown.

1. f(9) ≈ 6 means that at t = 9 (year 1977 + 9 = 1986) the cost to produce 1 watt of solar energy was $6

2. f(4) ≈ 25, which means at year 1981 (=1977 + 4) the cost was $25 per watt  

f(3.5) ≈ 28, which means at half of year 1980 (=1977 + 3.5) the cost was $28 per watt  

3. When f(t) = 45, t is equal to 2, which means that the year wass 1979 (= 1977 + 2)

4. From the graph we can compute the following table:

x  |  y

0  |  80

1   |  60

The general exponential decay formula is:

f(x) = a*b^x

where a is the initial value and b si the decay factor. Replacing with data from the table:

f(0) = a*b^0

80  = a

f(1) = a*b^1

60/80 = b

0.75 = b

Answer:

  1024 pi

Step-by-step explanation:

The area formula is ...

  A = πr^2

So, the radius is ...

  r = √(A/π)

For the given area, the radius of the cylinder is ...

  r = √(64π/π) = 8 . . . . cm

The height is said to be twice this value, so is 16 cm.

__

The volume of the cylinder is found from ...

  V = Bh

where B is the base area and h is the height. Our cylinder has a volume of ...

  V = (64π cm^2)(16 cm) = 1024π cm^3

Answer:

[tex]9^{2} -x^{2}[/tex]

Step-by-step explanation:

The figure is shown in the image attached.

Notice that the shaded light gray area can be calculated by the difference of the bigger square and the smaller square.

The area of the bigger square is: [tex]A_{big}=9^{2}[/tex]

The area of the smaller square is: [tex]A_{small}: x^{2}[/tex]

The difference between these areas is: [tex]A=9^{2} -x^{2}[/tex]

Therefore, the expression that can be used to find the light gray area is: [tex]9^{2} -x^{2}[/tex]

Additionally, the expression [tex]x(9-x)+9(9-x)[/tex] is also a right answer, because it's equivalent to the first answer.

[tex]x(9-x)+9(9-x)=9x-x^{2} +81-9x=81-x^{2} =9^{2} -x^{2}[/tex]

D ) the sum of the prices divided by seven

Step-by-step explanation:

The list below shows the prices of T-shirts at a clothing store.

{8, 10, 10, 12, 15, 15, 18}

( 8 + 10 + 10 + 12 + 15 + 15 + 18 ) ÷ 7

Which statement best describes the mean of this set?

D) the sum of the prices divided by 7

The statement best describes the mean of this set is the sum of the prices divided by 7.

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Mean of a set of data can be found by adding all the values of the data set and by dividing by the total number of values in the data set.

Given data set is the prices of T-shirts at a clothing store.

{8, 10, 10, 12, 15, 15, 18}

Mean of the data set = Sum of the prices/ Total number of values

Sum of the prices = 8 + 10 + 10 + 12 + 15 + 15 + 18 = 88

Total number of value in the set = 7

Mean = 88 / 7 = 12.574

Hence the mean can be found by adding up all the prices divided by 7.

Answer:

173.15 yards is the distance from tee to hole.

Step-by-step explanation:

Please refer to the image attached.

Let A is the position of tee and where the golfer is standing.

C is the position of hole.

CB is the vertical distance between greens and tee.

Angle of elevation, [tex]\angle BAC = 12^\circ[/tex]

To find: side AC.

Using trigonometric functions, we know that value of sine is:

[tex]sin\theta = \dfrac{\text{Perpendicular}}{\text{Hypotenuse}}[/tex]

Here [tex]\theta = \angle BAC = 12^\circ[/tex]

Perpendicular is side CB.

Hypotenuse is side AC.

[tex]sin12^\circ = \dfrac{\text{CB}}{\text{AC}}\\\Rightarrow \text{CB} = \dfrac{36}{sin12^\circ}\\\Rightarrow \text{CB} = 173.15\ yards[/tex]

Hence, 173.15 yards is the distance from tee to hole.

The probability is 21/32 or 65,625%

Step-by-step explanation:

You just add the number of girl students (including the ones that got an A) with the number of boys that got an A

Then you divide that number by the total of students (32)

The probability of choosing a girl or an A grade student is 19/32.

Probability is the chance or possibility to occur any selected event.

If the number of possible outcomes of an event is divided by the total number of outcomea of the event then it is called probability of that particular event.

In a maths class,

The total number of students = 32

No. of boys = 18 & no. of girls = 14

On an unit test, 5 boys made an A grade whereas 7 girls made an A grade.

The probability of choosing a girl = 14/32 = P(A) (say)

And, The probability of choosing an A grade student = 12/32 = P(B) (say)

Hence, the probability of choosing an A grade student who is a girl = P(A∩B) = 7/32

∴ The probability of choosing a girl or an A grade student =

P(A∪B) = P(A)+P(B)-P(A∩B)

            = 14/32+ 12/32-7/32

            = 26/32-7/32

            = 19/32

Hence, The required probability is 19/32.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Hello!

To arrange the data in a frequency table you have to determine the class intervals first. Normally you'd choose the number of intervals you want to work with and then calculate the class width by dividing the number ob observations, n, by the number of intervals, then, starting from the minimum value as the lower limit of the first interval, you add the width to calculate the upper interval. For the next interval, you use the upper limit from the previous one and add the width to determine the upper limit, and so on until you reach the desired number of intervals.

For this exercise the width was determined 0.50 and the lower limit for the first interval 0.00:

1st interval: 0.00+0.50= 0.50: [0.00; 0.50)

Then:

[0.50; 1.00)

[1.00; 1.50)

[1.50; 2.00)

[2.00; 2.50)

[2.50; 3.00)

Next is to arrange the data from least to greatest and count how many fit in each interval:

0 , 0,09, 0,18, 0,24, 0,31, 0,36, 0,39, 0,39, 0,41, 0,45, 0,55, 0,55, 0,63, 0,64, 0,64, 0,64, 0,64, 0,64, 0,69, 0,69, 0,71, 0,71, 0,73, 0,74, 0,78 ,0,79, 0,79, 0,79 ,0,83, 0,83, 0,83 , 0,85, 0,89, 0,91, 0,92, 0,92, 0,93,0,94, 0,98, 0,98 ,0,99, 0,99, 0,99,0,99, 1,01, 1,01, 1,01, 1,01, 1,22, 1,23,1,24, 1,24 , 1,24, 1,25 ,1,,25 , ,1,25,1,26 , 1,26, 1,27, 1,28 ,1,31 , 1,33 , 1,34 , 1,34 ,, 1,35, 1,35 , 1,38 , 1,39 , 1,41 , 1,42 , 1,42 , 1,43 , 1,44 , 1,44 , 1,45 , 1,46 , 1,49 , 1,49 , 1,56 , 1,56 , 1,62 , 1,63 , 1,65 , 1,65 , 1,75 , 1,77 , 1,78 , 1,78 , 1,82 , 1,85 , 1,96 , 1,98 , 2,19 , 2,21 , 2,23 , 2,24 , 2,47 , 2,49 , 2,95 , 2,97

See frequency table in attachment alongside with original data.

To check the distribution of the data I've made a QQ-plot with the Normal Quartiles (2nd attachment)

As you can see the Magnitude data is well-adjusted to the theoretical line for the normal distribution, this means that it is most likely that the data has a normal distribution.

Answer:

$390,900

Step-by-step explanation:

Given that.

Initial payment = $965

New rapayment = $925

In this case,

a 5/25 ballon mortgage simply means loan repayment for the first 5 years is at a fixed rate.

Which means the total amount she paid in the first five years was=

12 * 5 * $965

= $57,900

When she refinanced the payment with a 30 year mortgage, her total payment

= $925 * 12 * 30years
