Answer:

C) supplementary angles

D) straight angle

Step-by-step explanation:

There is a straight line, and when an angle is a straight it means its 180 degrees which makes it a supplementary angle and a straight angle.

There are no angles that are 90 degrees so its not complementary or a right angle.

Answer:

The probability that can afford to spend between $800 and $900

P(800≤X≤900) = 0.6826

The percentage of that can afford to spend between $800 and $900

P(800≤X≤900) = 68 percentage

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the mean of the Normal distribution = $850

Given that the standard deviation of the Normal distribution =  $50

Let 'X' be a random variable in a normal distribution

Let x₁ = 800

z_{1} = \frac{x_{1}-mean }{S.D} = \frac{800-850}{50} = -1

Let x₂ =850

z_{2} = \frac{x_{2}-mean }{S.D} = \frac{900-850}{50} = 1

<u><em>Step(ii):-</em></u>

The probability that can afford to spend between $800 and $900

P(800≤X≤900) = P(-1≤Z≤1)

                         = P(Z≤1) - P(Z≤-1)

                        = 0.5 + A(1) - (0.5 - A(-1))

                        = A(1) +A(-1)

                       = 2× A(1)       (∵ A(-1) =A(1)

                      = 2 × 0.3413

                      = 0.6826

The percentage of that can afford to spend between $800 and $900

P(800≤X≤900) = 68 percentage

Which of the following exponential regression equation best fits the data shown below. Please help ASAP. ☺️
stepladder [879]

Answer:

Option D [y=6.61\,*\,1.55^x] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

y=A\,e^{k\, x}

with optimized parameters:

A \approx 6.6114\,\,\,and\,\,\, k=0.4378321

Notice as well that since:

e^{0.4378321} \approx 1.5490

the exponential best fit can also be written:

y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}

and this expression is very close to the last option shown in your list of possible answers

the value of a car when purchased in 2008 was $21,500. It loses 12% of its value every year. What is the value of the car in 201
shusha [124]

Answer: the value of the car in 2019 is $5269

Step-by-step explanation:

It loses 12% of its value every year. This means that the value of the car is decaying exponentially. We would apply the formula for exponential decay which is expressed as

A = P(1 - r)^t

Where

A represents the value of the car after t years.

t represents the number of years.

P represents the initial value of the car.

r represents rate of decay.

From the information given,

P = $21500

r = 12% = 12/100 = 0.12

t = 2019 - 2008 = 11 years

Therefore

A = 21500(1 - 0.12)^11

A = 21500(0.88)^11

A = 5269
